Efficacy of Adjunctives in Periodontal Surgeries: An Evidenced-Based Summary.

Periodontal surgery is required to access the root surfaces in order to debride them of dental plaque and calculus, promote pocket reduction, create healthy bone architecture, and provide patients greater access to out-of-reach areas to maintain oral hygiene. The use of adjunctive agents and materials-enamel matrix derivatives, low-laser treatment, ozone, locally administered minocycline HCL, doxycycline gels, tetracycline fibers, chlorhexidine chips, granular beta-tricalcium phosphate, and hyaluronic acid, and the like-have been reported to improve pocket depth reduction, periodontal ligament healing, bone defect filling, and mechanical debridement during guided tissue regeneration/flap surgeries. However, the efficacy and benefits of these adjuvants compared to periodontal surgery alone is still widely debated. This evidence-based review critically evaluates and summarizes the efficacy of adjuvants used in periodontal surgery that have been reported in the literature.

Measurement of the open apices of mandibular first and second premolars to test the chronological age over 14 years: Study on a sample of south Indian children.

Age estimation is an integral part of forensic medical and dental practice. In many countries, the age threshold of 14 years is set to determine the minimum age for criminal responsibility. In the present study, the authors studied the final maturation of the first (IPM1) and second mandibular premolars (IPM2) by Cameriere maturity index and determined cut-offs at the age threshold of 14 years, and validate on the test sample. Orthopantomograms of 960 healthy south Indian children and sub-adults (480 boys and 480 girls) aged between 10 and 18 were analysed, 640 as training sample and 320 as a test sample. The results of logistic regression analysis with age (
