Öğe 3D evaluation of tooth crown size in unilateral cleft lip and palate patients(Wolters Kluwer Medknow Publications, 2020) Kaplan, M.; Görgülü, Sinan; Cesur, Emre; Arslan, Can; Altuğ, Ayşe TubaAim: The aim of this retrospective study is to evaluate and compare the 3-dimensional (3D) crown sizes of the left and right sides of upper and lower dental arches in patients with unilateral cleft lip and palate (UCLP). Materials and Methods: Dental casts of 94 patients all in permanent dentition were included in this study. Dental casts were divided into three groups as 36 casts with unilateral left cleft lip and palate (ULCLP), 18 casts with unilateral right cleft lip and palate (URCLP), and 40 casts without cleft (control). Mesiodistal (MD), buccolingual (BL), and gingiva incisal (GI) values of each tooth were measured by scanning the dental models with a high-precision optical 3D scanner. Paired t-test and independent t-test were used for statistical analysis. Results: U1 MD, U6 MD (P = 0.001) and BL (P = 0.01), L3 GI (P = 0.05) were greater in UCLP patients on the non-cleft side while U1 GI, L1 BL, L5 MD (P = 0.001), L4 MD, and BL (P = 0.01) values were found to be greater on the cleft side. Comparison of the cleft-sides and the control group showed that MD, BL, and GI dimensions of teeth on the cleft sides were generally found to be smaller, excluding the UR7 GI values for URCLP group (P = 0.05). Conclusion: In the measurements of teeth size, reliable and repeatable results were acquired through 3D software. Tooth size asymmetries can occur non-syndromic UCLP patients in both jaws. MD, BL, and GI dimensions of teeth are mostly found to be smaller in patients with CLP.Öğe An algorithm of dental/dentofacial-based options for managing patients with obstructive sleep apnoea referred to a dentist/dental specialist by a physician(Nature Publishing Group, 2016) Kılınç, Delal Dara; Didinen, SerhanThere are so many documents in the literature discoursing the aetiology, nature, diagnosis and treatment planning of obstructive sleep apnoea (OSA). Almost all of them mention that OSA has to be evaluated and treated through the multidisciplinary teamwork of physicians and dentists. Due to a lack in the literature, this article focuses on dentists' and dental specialists' role in the treatment algorithm of OSA.Öğe Applications of contemporary imaging modalities in orthodontics(Ondokuz Mayıs Üniversitesi, 2021) Cesur, Emre; Orhan, KaanThe validity of orthodontic diagnosis and treatment planning depends on the accuracy of the photos, models and radiograps to be obtained from the patient. One of the most important parts of diagnosis and treatment planning is the use of appropriate imaging method. Although lateral cephalometric radiographs are still the most preferred imaging method, other methods such as hand-wrist radiographs, panoramic radiographs, cone beam computerized tomography (CBCT), magnetic resonance imaging (MRI), and ultrasound are also frequently used. For this reason, it is important to know the advantages and disadvantages of all imaging methods for orthodontists in order to select the most suitable method for the patient. Although 2D imaging modalities are still frequently preferred in terms of their accessibility, CBCT use may come to the fore when precise imaging of hard tissues is desired. In cases where TMJ region and soft tissues are to be imaged, the use of MRI and ultrasound should be considered. Orthodontists should follow up the up-to-date usage areas of the developing imaging methods.Öğe Assessment of curve of spee in different malocclusions(Istanbul University Press, 2018) Sayar, Gülşilay; Oktay, HüsamettinPurposeThe aim of this study was to compare the depth of curve of Spee (COS) in Angle Class I, Angle Class II and Angle Class III malocclusions.Materials and methodsThe Samples were chosen among the diagnostic materials in Istanbul Medipol University Department of Orthodontics. Ninety plaster models were chosen, and were divided into 3 groups (n=30) according to Angle dental malocclusion classification. The depth of curve of Spee was measured on left and right sides of mandibular dental models and mean values were used as depth of curve of Spee. ANOVA test was used to evaluate normally distributed data. Comparison of the sides were performed by using paired sample t test. Significance level was set to p<0.05.ResultsThe depth of COS was found as deepest in Class II malocclusion (2.9 +/- 0.8 mm) and was relative flat in Class III malocclusion (2.1 +/- 0.9 mm) and the difference was statistically significant (p<0.05). No significant difference was found between Angle Class I and Class III malocclusions.ConclusionSince the depth of curve of Spee is increased in Class II malocclusions, this factor should be considered in treatment planning.Öğe Assessment of reliability of YouTube videos on orthodontics(AVES, 2019) Kılınç, Delal Dara; Sayar, GülşilayObjective: In addition to being an entertainment channel, YouTube is also one of the most popular visual information sources today. People search YouTube to consult also on orthodontics, as well as on many other topics. The objective of the present study was to analyze the quality and reliability of information of the videos on YouTube about orthodontics. Methods: YouTube was searched systematically by two researchers on orthodontics by using the keywords "Orthodontics,""Orthodontist" and "Orthodontic Treatment!Videos on the first three pages (60 videos) for each keyword were assessed. Researchers evaluated the reliability of the videos by using the Reliability Score (adapted from DISCERN) and the quality of the videos by using the Global Quality Score (GQS). Results: The mean GQS results were 2.6 +/- 1.3 for videos in the"Orthodontist" group, 3.2 +/- 13 for videos in the"Orthodontics" group, and 2.3 +/- 1.2 for videos in the "Orthodontic Treatment" group on a 5-point scale. The Reliability Score results were 2, 2, and 1.5 for videos in the "Orthodontist,""Orthodontics," and "Orthodontic Treatment" groups, respectively, on a 5-point scale. The Intraclass Correlation Coefficient results presented a positive relationship between the researchers. Conclusion: Owing to the lack of peer-review process and pre-upload scientific evaluation process, videos on YouTube can lead the public to misinformation.Öğe Assessment of the change in the nasal septum and nasal profile after le fort I with cone beam computed tomography(2024) Canbaz, Barış; Yılancı, HilalObjective: This study aimed to determine the relationship between nasal changes and the amount of advancement, impaction, and downward movement of the maxilla after Le Fort I osteotomy. Methods: The study included 48 patients who underwent Le Fort I surgery and had pre- and postoperative cone-beam computed tomography records. Changes in the nasal septum were evaluated by measuring septal deviation angles and volumes. In addition, nasolabial angle and width of nasal and alar base were examined. Groups were determined according to the movement of point A (the deepest point on the curvature of the maxillary alveolar process), using a threshold of 1.5 mm for vertical movements and 4 mm for sagittal movements. This resulted in the comparison of 6 groups of 8 people each. Results are presented as mean and standard deviation or median and range depending on the data distribution. Significance level was accepted as P < 0.05. Result: There were no significant differences for each group on its own septal deviation volume or angle values pre/postoperatively. Groups 3 and 5, which both had at least 1.5 mm of impaction, showed significant changes in both deviation angle and volume between the preoperative and postoperative measurements. Nasolabial angle did not show significant changes between groups. Alar base width and nasal width increase was significantly highest in Group 1, which has more than 4 mm sagittal movement and less than 1.5 mm vertical movement. Conclusions: Le Fort I osteotomy may lead to undesirable changes in the spatial positioning of the nasal septum. The results of this study suggest that maxillary advancement does not significantly impact septal deviation, whereas maxillary impaction increases the amount of deviation. In addition, nasal width and alar base width tended to increase, and the nasolabial angle tended to decrease slightly, regardless of the direction of movement of the maxilla after orthognathic surgery. Clinical Relevance: Surgeons should consider increased nasal septal deviation risks when planning impaction of the maxilla. The soft tissue changes in the nose vary according to different directions and amounts of Le Fort I surgery.Öğe Assessment of weight loss in the first three months of fixed orthodontic treatment(2019) Kılınç, Delal Dara; Sayar, GülşilayBackground: To asses weight changes in patients in the first three months of fixed orthodontic treatment. Materials and Methods: 53 patients (12 males, 41 females) in test group who needed fixed orthodontic treatment were selected. 50 subjects (14 males and 36 females) with similar conditions were selected as control. The mean age was for treatment group was 17.44±0.75 and was 17.67±0.85 for control group. Weight values of patients recorded immediately before bonding of brackets at beginning of treatment, 1 week after bonding and in orderly 1, 2 and 3 months after bonding. The same values were recorded also for the control group. Results: According to the results of Repeated Variance Analysis: time dependent changes were statistically significant (p:0.015) but, Time-Group interaction results were not statistically significant (p: 0.051). There was a statistically significant difference between the weight values according to the time intervals between the baseline values and 1.week and 1.month values; while there was not a statistically significant difference between the other time intervals. There was a statistically significant decrease in the mean weight values of treatment group according to the mean baseline values. Conclusion: Remarkable weight loss was observed in all patients in the first month of the treatment. Patients started to recover weight loss after second month of treatment.Öğe Clinical comparisons of different fixed orthodontic retainers(Dental Press International, 2022) Güneş, Recep Onur; Sayar, Gülşilay; Toygar, HilalObjective: The aim of this prospective clinical study was to compare the clinical outcomes of three different fixed lingual retainers, in terms of effects on periodontal health and success rate. Methods: Forty five patients aged 13 to 25 years were randomly assigned into three groups, using bonded upper and lower lingual retainers. The study groups were as follows: Group 1-BondA-Braid®, Group 2-everStick® ORTHO, Group 3-Super-Splint. The follow-up appointments were performed two weeks (Baseline=T0), one month (T1), three months (T2), and six months (T3) after the application of retainers. Plaque Index (PI), Gingival Index (GI), Probing Depth (PD), Bleeding in Probing (BOP) and Retainer Failure were assessed at each appointment. Results: The everStick Ortho group showed significantly lower PI values on the upper-lower lingual side after three (p=0.008) and six (p=0.001) months. The everStick Ortho group had significantly lower upper lingual (GI) levels after six months, and lower lingual side levels after one month. The Super-Splint group showed significantly lower PD values on the upper lingual side after six months. The everStick Ortho group presented significantly lower BOP levels after six months on the upper lingual side. No significant differences between the groups (p>0.05) in terms of retainer failure were found. Conclusions: The everStick Ortho group presented better results in terms of periodontal health. The failure rates of the retainers were similar.Öğe Comparison of laser and piezo incisions to accelerate orthodontic tooth movement - A pilot rat model study(2021) Yılancı, Hilal; Kara, Burçak; Ramoğlu, Sabri İlhanAim: The aim of this study was to determine changes in bone structure after laser and piezo incisions evaluated with micro-computed tomography (micro-CT). Materials and Methods: Forty-eight adult male Sprague Dawley rats were randomly divided into 4 groups: no additional intervention to accelerate tooth movement (n=15), laser incision (n=15), piezocision (n=15), and control (n=3). These groups were divided into subgroups based on duration of applied force: 0, 3, 7, 14, 21, and 28 days. Piezo and laser incisions were made vertically on the mesial palatal side of the left maxillary molar without flap elevation. Tooth movement, bone volume, and bone mineral density were evaluated with micro-CT. P values less than 0.05 were considered statistically significant. Results: There were no significant differences in bone mineral density, bone volume, or amount of tooth movement between time points in any of the groups. The amount of tooth movement was significantly different between the groups at day 21. Conclusion: These findings provide some initial basic understanding of changes in the bone following tooth movement alone and with piezocision and laser incisions. Larger sample sizes are needed to better elucidate their effects.Öğe Comparison of shear bond strength of three different adhesives used as temporary bite raiser in daily orthodontic practice(Elsevier Masson Sas Editeur, 2018) Kılınç, Delal Dara; Sayar, GülşılayObjective: The aim of this study was to evaluate the shear bond strength of three different adhesives (Transbond XT, Light Cure Adhesive, 3M Unitek; Transbond Plus, Light Cure Band Adhesive, 3M Unitek; Transbond Supreme LV, Low Viscosity Light Cure Adhesive, 3M Unitek), which were applied to the etched enamel of occlusal faces of mandibular molar teeth to gain bite opening. The null hypothesis was that there is no statistically significant difference between shear bond strength of these three adhesives. Materials and methods: Forty-eight human molar teeth were equally divided into three groups (n = 16). Teeth were embedded in self-curing acrylic resin and were polished and etched. Adhesives were applied on the teeth and all adhesives were light cured for 20 seconds. Universal Testing Machine was used for shear bond strength tests with a crosshead blade loaded at a crosshead speed of 1 mm/min. Evaluating the type of failure was done by using Adhesive Remnant Index (ARI) was used to evaluate the remaining adhesive on the tooth. Results: One-way analysis of variance (ANOVA) was used to determine the significant differences between the three different orthodontic adhesives. There was no significant difference (P = 0.774) between the groups according to ANOVA test. According to Kruskal-Wallis test there was no statistically significant differences in ARI scores among groups (P <0.01). Conclusion: The null hypothesis was accepted. There was no statistically significant difference among their bond strength values. All of three materials can be used as temporary bite openers.Öğe Comparison of shear bond strength of threedifferent adhesives used as temporary biteraiser in daily orthodontic practice(Elsevier Masson, 2018) Kılınç, Delal Dara; Sayar, GülşilayObjective: The aim of this study was to evaluate the shear bondstrength of three different adhesives (Transbond XT, Light CureAdhesive, 3M Unitek; Transbond Plus, Light Cure BandAdhesive, 3M Unitek; Transbond Supreme LV, Low ViscosityLight Cure Adhesive, 3M Unitek), which were applied to theetched enamel of occlusal faces of mandibular molar teeth togain bite opening.

The null hypothesis was that there was no difference between the SBS of the treated and untreated rebonded brackets on treated and untreated enamel surfaces. Materials and Methods: Fifty extracted premolars were bonded by the same conventional bonding method and then debonded, and the SBS of each tooth was recorded. The debonded brackets and teeth were divided into two equal groups. In the first group, the debonded brackets were recycled by direct flaming followed by alumina oxide sandblasting, and the teeth were treated with a tungsten carbide bur applied with a low-speed hand piece. In the second group, neither the teeth surfaces nor the bracket bases were treated. Rebonding was performed followed by debonding, and the SBS of each tooth was recorded again. Results: Both rebonded bracket groups showed lower SBS results than that of the first debonding tests. A statistically significant difference was found within the untreated bracket groups between the first and second debonding test (P <0.001). Conclusion: The rebonding of treated enamel surfaces and treated bracket bases showed higher SBS values compared to the untreated ones. The null hypothesis was rejected.Öğe Comparison of the soft and hard tissue effects of two different protraction mechanisms in class III patients: A randomized clinical trial(Springer Heidelberg, 2015) Çeliko?lu, Mevlüt; Yavuz, İbrahim; Unal, Tuba; Oktay, Hüsamettin; Erdem, AbdulvahitObjective The objective of the present study is to test the null hypotheses that there were no significant differences for hard and soft tissue changes induced by mini maxillary protractor (MMP) and face mask and rapid maxillary expansion (FM/RME). Materials and methods Thirty-two patients who met the criteria were randomly divided into two groups: 16 patients (males/females 7/9) in the MMP group and 16 patients (males/females 6/10) in the FM/RME group. The patients in both groups were instructed to wear the appliances for at least 20 h per day until a 2-mm positive overjet was achieved. Hard and soft tissue profile changes observed by MMP and FM/RME were compared using paired and Student's t tests. Results Class III malocclusion and negative overjet were improved by means of skeletal changes in conjunction with upper incisor proclination and lower incisor retroclination in both groups. Maxilla and surrounding soft tissues (SNA, Ls-E, and Ls-PMV) were significantly moved anteriorly with less rotation of the palatal plane in the MMP group. Mandibular incisors were found to be more retrusive in the FM/RME group (p = 0.024). Conclusions Both groups showed similar effects except more anterior movement of the maxilla and surrounding soft tissues with less rotation of the palatal plane and retrusion of lower incisors in the MMP group.Öğe Comparison of youtube and youtube shorts videos about clear aligners(2024) Yılancı, Hilal; Canbaz, BarışObjectives: The aim of this study was to compare the quality and characteristics of information about clear aligners between YouTube and YouTube Short videos. Material and Methods: YouTube video was searched using the keyword “aligner.” After ranking the results according to relevance, 100 of the first 157 YouTube videos and 100 of the first 140 YouTube Shorts were evaluated. Videos were classified into five groups as dentist/specialist, hospital/clinic/university, commercial, layperson, and other. The video information and quality index (VIQI) and DISCERN index were used to evaluate the quality and usefulness of the videos. Data were analyzed using International Business Machines(Ibm) Statistical Package for the Social Sciences (SPSS) statistics version 23. Level of significance was accepted as P < 0.05. Results: Only 9% of YouTube videos, content quality was found to be good. As DISCERN scores decreased, a significant decrease was present in the number of views, comments, likes and dislikes, total video length, VIQI, viewer interaction, and viewing rate. The United States of America (USA) was the leading country by producing 54% of YouTube videos. However, India was the predominant source of YouTube Shorts videos, with 83%. Invisalign was the most frequently mentioned brand of aligner in both YouTube and YouTube Shorts videos. Conclusion: Orthodontists should be aware that the data available on the internet is incorrect or insufficient and should guide their patients correctly with additional data. Likewise, they should guide them on how to access up-to-date and accurate data.Öğe Conductive hearing loss associated with dentofacial deformities and orthodontic treatment modalities(Nova Science Publishers, Inc., 2011) Oktay, Hüsamettin; Kılıç, NihatThe stomatognathic system consists of mouth, teeth, upper respiratory tract, pharynx, and other structures related with mastication, deglutition, respiration and speech. This system consists of 27 bones including maxilla and mandible which constitute two main skeletal parts of face. Congenital and/or developmental disorders in any hard and/or soft tissues of stomatognathic system and/or functional aberrations will affect the other components of this system. The stabilization of various parts of the stomatognathic system together with its functional and anatomic integrity has been the center of interest among orthodontists for years. It has been documented in clinical and experimental studies that a close relationship exists between respiratory disturbances and dentofacial growth and development. Mouth breathing leads to develop some pathologic adaptations in postural and morphological characteristics of the stomatognathic system, and these abnormal habits cause serious negative effects on the normal development of nasomaxillary and dentofacial structures during the growth period. Maxillary deficiency or constriction of the maxillary dental arch, concomitant with a high palatal vault, is one of the most common orthodontic problems seen in the maxillofacial region. Main orthodontic manifestations of this skeletal development syndrome are palatal constriction and deficiency, deep palatal vault, narrowed maxillary arch, and posterior crossbite. Simultaneous presence of this syndrome and abnormal breathing pattern can lead to serious problems such as obstructive sleep apnea, recurrent otitis media, and conductive hearing loss related with Eustachian tube dysfunctions. Congenital deformities such as cleft lip and palate are also serious problems seen in dentofacial region. The cleft patients generally have posterior crossbite, narrowed maxillary arch, deep palatal vault, abnormal breathing pattern, increased nasopharyngeal and middle ear infections as well as Eustachian tube dysfunctions, which cause conductive hearing loss. This chapter aims to evaluate conductive hearing loss associated with dentofacial deformities including the skeletal development syndrome and cleft lip and palate. The present chapter will also assess the effects of dentofacial orthodontic/orthopedic treatment procedures such as semi-rapid or rapid maxillary expansions on conductive.Öğe Crouzon syndrome with multiple supernumerary teeth(Medknow Publications & Media Pvt Ltd, 2017) Torun Sayar, Gülşiyar; Akbulut, AslıhanCrouzon syndrome (CS) is an autosomal dominant disorder characterized by craniofacial deformities caused by the early closure of cranial sutures. It is diagnosed by the presence of a flat sphenoid bone, protrusion of eyeballs (exophthalmos), and midfacial hypoplasia. Although hypodontia is usually present in cases with CS, supernumerary teeth are rarely seen. A 16-year-old male patient with CS was referred to our clinic. He had a high forehead, beaked nose, hypertelorism, palpebral ptosis, and asymmetrical orbits. Bilateral multiple supernumerary teeth were observed in his upper and lower jaws. Early diagnosis of CS is helpful in dental and craniofacial treatment. Because of multiple facial and oral problems, this patient required a multidisciplinary treatment approach.Öğe Determination of the thickness of the safe enamel for laminate veneer preparation and orthodontic stripping by CBCT(Wolters Kluwer Medknow Publications, 2021) Yağcı, Filiz; Türker, Gökhan; Yılancı, HilalAim: The purpose of this study is to determine the thickness and limitation of the safe enamel for laminate veneers and orthodontic stripping applications. Enamel thickness (ET) was determined in detail for each tooth and also it was examined whether there was a relationship between the mesiodistal crown width of the teeth and the thickness of the enamel and whether there was a sexual dimorphism. Subjects and Methods: CBCT records of 101 subjects (mean age: 20.88 ± 2.48 years) were examined. ET was measured both mesial and distal region of maxillary and mandibular incisors, canines, and premolars in different levels as cervical, middle, and incisal (occlusal) 1/3. Paired t-test, student t-test, Mann-Whitney U-test and Pearson correlation coefficients a simple linear regression analysis used for statistical analysis. Results: ET of mandibular first premolars and canines was thicker at right side. Mesial enamel of maxillary first premolars, canines, lateral incisors and mandibular premolars and canines were significantly thicker than distal enamel. The mesial enamel of mandibular first premolars was significantly thicker in females. Also, males' maxillary laterals were significantly larger. All premolars had a correlation between mesio-distal crown widths and ET. Conclusions: Mesial and distal ET was unique for each one tooth at different levels. The relationship between ET and crown dimensions of all premolar teeth was also determined.Öğe Distinguishing hard and soft tissue facial morphology among class I and class III children: A cephalometric assessment(2018) Kılıç, Nihat; Çatal, Gülhan; Oktay, Hüsamettin; Çelikoğlu, MevlütAim: To assess the sagittal soft and hard soft tissue morphology of growing Class III patients in comparison with a Class I control subjects. Materials and Methods: Forty-one female children with Class III malocclusion and 30 Class I female children were included in the study. Eight linear and 6 angular measurements were made on lateral cephalograms to evaluate soft tissue and skeletal characteristics. Results: The subjects with Class III malocclusion showed a retrusive maxilla (A-y distance, 48.52±2.53) and upper lip (Ss-y distance, 64.14±3.26), a protrusive mandible (B-y distance, 56.15±5.49) a prominent chin (Pog’-y distance, 70.65±6.87), retroclined lower incisors (IMPA, 87.14±5.68), and increased vertical dimensions (SN-GoMe, 36.49±5.29) compared to control subjects. Conclusions: Our findings indicated that soft and hard tissue characteristics of Class III subjects are distinct from Class I subjects in the middle region and lower third of the face. Orthopedic traction of mid-face arguably started earlier as a first treatment protocol to obtain balanced facial profile in Class III subjects.Öğe Do children with Wilson's disease have distinct craniofacial morphology? A cephalometric study(Elsevier Ireland Ltd, 2013) Kılıç, Nihat; Sümbüllü, Muhammed Akif; Ertekin, Vildan; Çatal, Gülhan; Çakur, Binali; Oktay, Hüsamettin; Selimoğlu, Mukadder AyşeObjectives: Patients with Wilson's disease (WD) develop osseous changes such as osteoporosis, spontaneous fractures, areas of sclerosis and demineralization of maxillary and mandibular bones, and neurologic symptoms including swallowing dysfunctions, which may affect dento-facial growth. However, dento-maxillo-facial structures of these patients have never been investigated. The present study aimed to discover if subjects with WD have different dentofacial structures. Methods: Lateral cephalometric films of 13 children (5 males and 8 females) with WD and of 15 normal subjects (6 males and 9 females) were evaluated. Mean ages of the patients and controls were 12.62 +/- 3.09 years and 12.01 +/- 1.38 years, respectively. Lateral cephalometric cranial films of all subjects were taken in the same cephalostat in a habitual and unstrained body posture. Thirteen linear and 11 angular parameters were measured to describe the craniofacial characteristics of the subjects. Results: Statistical analysis showed that there is no statistically significant difference between parameters of normal children and children with WD, with the exception of palatal plane inclination. The inclination of palatal plane was higher in children with WD than in normal subjects. Conclusions: Children with WD and healthy children have approximately the same dento-maxillo-facial structures. However, increased palatal plane inclination may be a finding of WD.Öğe Does audiovisual information affect anxiety and perceived pain levels in miniscrew application? - A within-person randomized controlled trial(Springer, 2019) Çalık Koseler, Berra; Yılancı, Hilal; Ramoğlu, Sabri İlhanBackground: Anxiety can cause difficulties during surgical procedures. The main objective of this study was to evaluate changes in patients’ anxiety and perceived pain levels after receiving audiovisual and verbal information about miniscrew application. Materials and methods: Eighty-eight patients (30 males and 58 females) with a mean age of 18.18 ± 5.39 years who had fixed orthodontic treatment and required miniscrew anchorage took part in this questionnaire-based randomized controlled trial. The participants were randomly allocated to two groups and either watched a video depicting miniscrew application (study group, 44 patients) or were informed verbally about the procedure (control group, 44 patients) before miniscrew placement. The audiovisual information was given via a video containing footage of local anesthesia injection, topical antiseptic application, and miniscrew insertion. The Spielberger State-Trait Anxiety Inventory (STAI) was used to measure anxiety immediately before miniscrew application. Self-drilling miniscrews (8 mm length, 1.5 mm diameter; Aarhus System Miniscrews, American Orthodontics, Washington, USA) were placed in posterior buccal interdental region. Each patient received only one miniscrew. Postoperative pain (PP) was determined using a 100-mm horizontal visual analog scale (VAS). Results: State and total anxiety scores were significantly higher in the study group than in the control group (p = 0.009 and p = 0.011 respectively). The mean PP scores (SD) for control and study groups were 12.86 (14.22) and 12.8 (16.22), respectively. The results of Mann–Whitney U test showed no significant difference (p> 0.05). Participants’ PP scores did not have a significant effect on state, trait, or total anxiety scores. There was a weak but significant positive correlation between trait anxiety and state anxiety scores in both groups. Conclusion: Using an audiovisual method to inform patients about miniscrew placement increased anxiety levels but did not affect pain perception.
