Periodontal disease is the most common oral disease in adults. Traditional nonsurgical periodontal therapy involves subgingival removal of hard and soft deposits on the root surface, along with maintenance of good oral hygiene. Nonsurgical periodontal therapy can either be definitive or part of the initial phase before surgical therapy. Mechanical therapy, either with hand or ultrasonic instrumentation, is the keystone of nonsurgical periodontal therapy. This requires considerable amounts of time and a high level of operator skill. The use of appropriate instruments greatly increases clinical efficiency. This article discusses the use of ultrasonic and hand instrumentation, along with recent advances, and the benefits of adjunctive therapy during nonsurgical periodontal therapy.

Diabetes and periodontitis are chronic inflammatory disorders that contribute to each others’ severity and worsen each others’ prognosis. Studies have shown that patients with diabetes are at increased risk of developing periodontitis, and that diabetics with untreated periodontitis have more difficulty controlling serum glucose. Periodontal treatment that reduces gingival inflammation aids in the control of hyperglycemia. Periodontitis is accompanied by gingival bleeding and the production of an inflammatory exudate termed gingival crevicular fluid (GCF) that arises from the inflamed gingival tissues surrounding the teeth. GCF contains byproducts of connective tissue degradation, enzymes from host and bacterial cells, cytokines and other inflammatory mediators, and has been studied for screening blood glucose and for biomarkers of both diabetes and periodontitis. This review focuses on the inter-relationship between diabetes and periodontitis and the biomarkers common to both these diseases that may enable earlier detection, targeted preventive measures and individualized therapeutic intervention of these chronic conditions.

Aim:The present study's aim was to assess the pattern of palatine ridges/rugae to identify gender. Materials and methods:This study consists of a total of 50 participants (25 males and 25 females). Participants of the age range of 20 to 50 years were selected from the outpatient department. According to the shape and size of the patient's arches, maxillary impression trays were selected using alginate, and casts were poured subsequently. With the help of a sharp graphite pencil, the palatine ridges were delineated to make it prominent, and on either side of the midline, the number of rugae was counted and the length measured. Using these parameters, the pattern of rugae was determined. Data were analyzed using independent sample t-test. The level of significance was set at 5%. Results:Males had more number of palatal rugae (mean 5.96 ± 0.88) compared with females (5.24 ± 0.77), and there was a statistically significant association between them. The mean length of palatal rugae was more in males (6.25 ± 1.15 mm) than females (5.16 ± 1.40 mm), and it was found to be a statistically significant association. The straight pattern was more common in both males and females (2.56 ± 1.08, 2.32 ± 0.85 respectively) than other patterns.
