The Effect of Light-emitting Diode Light Intensities and Duration of Cure on Pulpal Wall Temperature among Different Classes of Teeth.

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.

Exploring Genetic Link of Residual Ridge Resorption in Completely Edentulous Individuals: A Prospective Case-Control Clinical Study.

Background: Residual ridge resorption presents obstacles in prosthodontic treatment, affecting denture stability and the success of dental implants. Genetic elements, specifically the single nucleotide polymorphism (SNP) 1772C>T variant within the hypoxia-inducible factor 1 subunit alpha (HIF-1α) gene, are hypothesized to contribute to residual ridge resorption progression. Nevertheless, its impact remains insufficiently investigated, especially within the context of South Indian populations.

Matrix metalloproteinase inhibitors in restorative dentistry.

Matrix metalloproteinases (MMPs) have been identified as agents that disintegrate the collagen structures of dental hybrid layers, resulting in reduced restorative bond strength. Multiple MMP inhibitors (MMPIs) are known to counteract this degenerative mechanism, thereby preserving bond strength and promoting the longevity of resin-based restorations. Additionally, literature suggests that certain MMPI materials possess antimicrobial/anticariogenic properties, potentially reducing the risk of secondary caries development.

A Systemic Review and Meta-analysis on Natural Resistance-associated Macrophage Protein 1 (3'-Untranslated Region) and Nucleotide-binding Oligomerization Domain-2 (rs8057341) Polymorphisms and Leprosy Susceptibility in Asian and Caucasian Populations.

Enhancing the Adaptation of Single Non-compression Miniplate in the Management of Angle Fractures of the Mandible for Better Surgical Outcome-A Technique Modification.

The anatomical characteristics and the cortico-cancellous nature of bone disrupted by the presence of teeth make the mandible more vulnerable to fractures during traumatic injuries of the face. Fractures of the angle region constitute about 30% of mandibular fractures due to the change in dentate bone to the lateral flare of ramus, change in grain pattern of the bone, and presence of third molars all weakening the region making it fragile and thus fracture. Several studies corroborated the effectiveness of Champy's technique as to have the lowest complication rate when compared to the other techniques.
