Genetic polymorphisms influence shear bond resistance of orthodontic brackets
(Elsevier, 2020)
Objectives: The purpose of this study was to determine if shear bond resistance of orthodontic brackets bonded to enamel is associated with genes implicated in the enamel mineralization process.Methods: Ninety-two permanent, ...
Alteration of exon definition causes amelogenesis imperfecta
(SAGE Publications Inc., 2020)
Amelogenesis imperfecta (AI) is a collection of genetic disorders affecting the quality and/or quantity of tooth enamel. More than 20 genes are, so far, known to be responsible for this condition. In this study, we recruited ...
Prevalence of postoperative secondary bleeding and its relationship with intraoperative massive bleeding in patients undergoing orthognathic surgery
(Elsevier, 2021)
Introduction: Postoperative bleeding after orthognathic surgery is a rare but life-threatening complication. Maxillary surgery is the main cause of bleeding, after which excessive epistaxis can occur until the 10th ...
Stability of dental implants with sandblasted and acid-etched (SLA) and modified (SLActive) surfaces during the osseointegration period
(Tabriz University of Medical Sciences, 2021)
Background. The surface properties of implants are effective factors for increasing the osseointegration and activity of osteoprogenitor cells. This study compared the stability of dental implants with sandblasted and ...
Preventive and therapeutic effects of relaxin on bisphosphonate-related osteonecrosis of the jaw: An experimental study in rats
(Universidade Estadual Paulista, Institute of Science and Technology of Sao Jose dos Campos, 2020)
Objective: Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a challenging complication of chronic bisphosphonate (BP) use. The hormone relaxin is able to induce the multistep differentiation process of human ...
Effect of fluoride releasing bonding materials on shear bond strength of orthodontic brackets
(AVES, 2020)
Objective: The aim of the present study was to compare the shear bond strength (SBS) of three different fluoride-releasing bonding agents with a conventional adhesive system.Methods: Eighty-four extracted human premolar ...
Activation of matrix-bound endogenous proteases by self-etch adhesives
(NLM (Medline), 2020)
The study evaluated changes in total enzymatic activity and degradation of demineralized dentin following the application of universal or self-etch adhesives. The universal adhesives -Scotchbond Universal (SU) and All-Bond ...
Cleaning efficacy of poly-ether-ether-ketone tips in eliminating cement remnants around implants with different abutment heights
(Allen Press Inc, 2020)
The excess cement not removed after the cementation of fixed implant-supported restorations may cause loss of peri-implant attachment or adjacent bone. The aims of this study were to evaluate the amount of residual cement ...
The effect of different final irrigation regimens on the dentinal tubule penetration of three different root canal sealers: A confocal laser scanning microscopy study in vitro
(Hindawi Limited, 2021)
This study evaluated the effects of different final irrigation regimens on the dentin tubule penetration of three different root canal sealers using confocal laser scanning microscopy (CLSM). A total of 160 single-rooted ...
Use of resonance frequency analysis to evaluate the effects of surface properties on the stability of different implants
(Wiley, 2020)
Objectives We performed a randomized clinical study evaluating the stability of implants with different surfaces (alkali-modified or sandblasted) via resonance frequency analysis (RFA). Materials and Methods Fourteen ...
