Context: Human leukocyte antigens (HLAs) have an important role in the determination of susceptibility and resistance to periodontal diseases in humans, which may vary from population to population.
Aims: The aim of this study was to find out the association of HLA Classes I and II genes with chronic periodontitis in East Indian population.
Materials And Methods: In a cross-sectional study design, a total of sixty participants of chronic periodontitis (CP) (mean age: 44.12 ± 5.85) and sixty subjects of periodontal disease-free controls (NP) Periodontitis free controls (mean age 41.85 ± 7.71) were analyzed for their various HLA combinations using serologic (microlymphocytotoxicity test) method. The results are further compared with the HLA profile of 100 samples of blood donors for which periodontal status was unknown. All the data were statistically analyzed by applying Chi-square test.
Results: HLA-B7 ( = 0.003), DR7 ( = 0.001), DR53 ( = 0.001), and DQ3 ( = 0.001) were identified as susceptible phenotypes to CP, whereas HLA-A1 ( = 0.010), A3 ( = 0.001), and Cw4 ( = 0.001) phenotypes were identified to be associated with disease resistance.
Conclusion: The HLA-B7, DR7, DR53, and DQ3 alleles may represent as risk factors for CP in Eastern Population of India, whereas HLA-A1, A3, and Cw4 may indicate to protective factors for CP of the same.

Dental implants are now a standard solution for replacing missing teeth, even in patients with a history of chronic periodontitis. India is often referred to as the "diabetic capital of the world," a title that reflects the country's alarming rates of diabetes prevalence. However, the risk of complications, such as peri-implantitis and implant failure, remains a concern for these patients.

Periodontitis is a chronic inflammatory disease that destroys tooth-supporting structures and poses significant public health challenges due to its high prevalence and links to systemic health conditions. Traditional treatments are effective in reducing the inflammatory response and improving the clinical symptoms of periodontitis. However, these methods are challenging to achieve an ideal treatment effect in alveolar bone repair.

Aim: This study aimed to evaluate the effects of chronic consumption of two sugar-sweetened carbonated soft drinks - one containing caffeine (Coca-Cola®) and one without (Sprite®) - on the progression of periapical lesions and the levels of pro-inflammatory cytokines in rats.
Methodology: Twelve Wistar rats were divided into three groups (n = 4): Control group, Coca-Cola group and Sprite group. The rats in Coca-Cola and Sprite groups were given ad libitum access to their respective soft drinks for 3 months, while the Control group received filtered water.
