Development of Oral Bio-banks Past, Present and Future; Challenges and Opportunities.

Biobank involves collecting, processing, storing, and organizing biosamples, along with relevant personal and health information such as medical history, family records, genetics data, and lifestyle details, for medical research and clinical care. Oral biobanking is a recently evolved field alongside the rising of precision medicine due to recent research findings in oral oncology and other oral complaints, namely caries and periodontal disease. The common samples in oral biobanks are matured and primary teeth, dental pulp cells, oral biopsies, oral rinses, saliva, and swabs from the buccal region. Moreover, biobank should not conceive of as a static collection of samples and data but as a dynamic resource for developing novel techniques that meet current scientific demands through international networking. However, the major bottlenecks associated with oral biobanks are privacy, processing of samples, normalization of data, extended durability of interest markers of banked samples, and financial sustainability of biobanks. Thus in this correspondence, we argue that an alternative approach is urgently needed to protect the interests of many stakeholders.

Approaches for Implant Stage II Surgical Exposure: A Retrospective Analysis.

OBJECTIVES: The objective of the present study was to evaluate the various approaches used for implant stage II surgery before the restorative phase. MATERIALS AND METHODS: A retrospective study was carried out using data from 486 patients who had undergone stage II implant surgery at Saveetha Dental College and Hospitals, Chennai. The age, gender, technique of implant recovery, and site of recovery were noted. The data were collected and statistical analysis was done using IBM SPSS version 24.0. RESULTS: The mean age of the patients was 39.9 ± 12.9.The most common approach used in stage II implant surgery was found to be a full thickness flap accounting for about 76.75%. Chi-square test for association between the site of implant and the technique used for recovery was statistically not significant (p value % 0.187). CONCLUSION: Given that there is some loss of keratinized tissue during a flapless tissue punch technique, the full thickness flap provides an opportunity to preserve the keratinized gingiva and to form a healthy marginal attachment mucosa around the implants.
