Background: The study explores the impact of microleakage on bracket (metal/ceramic) debonding and the occurrence of white spot lesions during orthodontic treatment. Various curing techniques are employed to assess shear bond strength (SBS) and microleakage in both metal and ceramic brackets.
Materials And Methods: A total of 120 samples were divided into six groups, each consisting of 20 samples.
Introduction: The thermal changes during light curing of resin-based composites (RBCs) are recognized, but there is a lack of information about temperature changes in pulp tissue under different curing protocols, especially during bonding of orthodontic brackets onto the tooth surface. In the present study, pulpal temperature (PT) variation induced by the use of four different light cure intensities and different durations of cure among different classes of teeth was measured.
Materials And Methods: A total of 80 different classes of human extracted teeth (maxillary and mandibular central incisor, lateral incisor, canine, premolar, and molar) were irradiated at the same distances with four visible light curing intensities.
Background: Knowledge of bone density in maxilla and mandible will allow the clinician to plan the anchorage strategies and placement of implants with necessary precautions. The study aims to evaluate the deflection changes of titanium alloy self-drilling mini implants from the intended path that occurs during placement in varying bone densities.
Material And Methods: 63 titanium alloy self-drilling mini implants of the lengths 6mm, 8mm, and 10mm with diameter of 1.
Background: Laser etching addresses the disadvantages of conventional acid etching technique, such as enamel decalcification and formation of white spot lesions. The aim of the present study was to evaluate and compare the shear bond strength (SBS), adhesive remnant index (ARI), and the surface characteristics of the samples treated with conventional acid etching and Er, Cr: YSGG laser etching with variable output power and time durations.
Methodology: The study sample included 78 extracted teeth divided into six groups of 13 teeth each, and 3 samples from each group were utilized for analyzing etch patterns, and the remaining 10 teeth from each group were used for evaluating the shear bond strength.
Aim: To study the associations of dermatoglyphic pattern and the dental archform among the young adult population.
Materials And Methods: The sample consisted of 150 randomly selected patients, within the age ranging from 15 to 25 years. The fingerprint patterns of the study subjects were recorded with a rolling impression technique using blue printer ink and the archform was assessed from the cast prepared from the impression of their lower dental arches.
