Objective: To assess the allele rs 1143634 in IL-1β and rs1800587 in IL-1α in patients for orthodontically induced external apical root resorption (EARR).
Material And Methods: Intra-oral periapical radiograph (IOPA) of maxillary incisors of 142 Patients were evaluated for resorption at two time points; before the start of fixed mechanotherapy (T1) and after one year of treatment (T2). The individuals with root resorption<2mm were categorized as a control group (group 1; n=90), and resorption>2mm were categorized as case group (group 2; n=52).
Article Synopsis
- The study aimed to explore the levels of Matrix metalloproteinases-9 (MMP-9) and Tumor necrosis factor-alpha (TNF-α) in the pulp of teeth with different stages of inflammation among diabetic and non-diabetic patients.
- A total of 77 patients were divided into two main groups based on their diabetes status and further categorized into subgroups depending on their pulpitis type (symptomatic reversible or irreversible).
- Results showed that both MMP-9 and TNF-α levels were significantly higher in cases of symptomatic irreversible pulpitis compared to reversible pulpitis, highlighting a possible link between these biomarkers and the severity of pulp inflammation.
Objective: To compare demineralization around orthodontic brackets cured by conventional method and transillumination method.
Materials And Method: Sixty freshly extracted human premolar teeth were divided into four groups. Group 1: Brackets bonded with conventional method of bonding by curing labially for 40 sec.
Introduction: Oxidative stress has been implicated in tumourigenesis by affecting the actions of various protein kinases and transcription factors, and resulting in damage to DNA structure by the deamination of nucleotides and the generation of free radicals. Derangements in the antioxidant defence mechanism have been considered in the pathogenesis of oral cancer.
Aim: To evaluate and compare the serum levels of nitric oxide and vitamin C in cases of Oral Potentially Malignant Disorders (OPMDs) and Oral Squamous Cell Carcinoma (OSCC) and healthy controls.

Objective: To assess inter and intra observer variability in grading oral epithelial dysplasia (OED) using Smith and Pindborg grading system, WHO classification system and Brothwell DJ et al. classification system.
Study Design: In the study 45 histological tissues of dysplasia, 15 each of mild, moderate and severe dysplasia were coded and blindly graded by three observers in three grading systems.
