This study suggests that a routine preprocedural mouthrinse could eliminate the majority of bacterial aerosols generated by the use of an ultrasonic unit, and that 0.2% chlorhexidine gluconate is more effective than herbal mouthwash.

Successful implant treatment requires prosthetically driven placement of an implant, primary stability at placement, and careful living bone management. The resorptive changes of alveolar bone are an inevitable process following tooth loss, periodontal disease or trauma which causes bone defects. This results in various aesthetic and functional complications such as soft tissue recession, infection and inflammation. Various methods have been tried and advocated for augmenting these bone deficiencies. Guided Bone Regeneration (GBR) is a successful modality for bone augmentation with a wide range of indications and helps restore the alveolar ridge dimensions. It utilises the principle of Guided Tissue Regeneration (GTR) for space maintenance within a bony defect. Different types of barrier membranes are being utilised along with various bone grafts in GBR. Thorough knowledge regarding the biology of bone is required before the initiation of any bone augmentation procedure. A combination of Collagen Membrane (CM) and graft material was found successful for GBR. Hence, this review focuses on presentation of best available evidence for various aspects of GBR.

Objective The aim of the study is to assess the knowledge, awareness, attitude, and opinion concerning dental stem cells among faculty, postgraduates, and interns in a dental school. Materials and Methods A questionnaire consisting of 12 questions was circulated among the 150 participants (50 faculty, 50 postgraduate students, and 50 interns). A questionnaire was prepared that could assess the basic knowledge on stem cells (dental) based on similar previous studies. The questionnaire data were entered by the investigator in Microsoft Excel 2010 on a corresponding day. Using Predictive Analytics Tools (Version 18), the analysis was done. Probability ratios by Pearson were used to analyze the application of knowledge, perception regarding stem cells. Results The survey participants consisted of ~73% of females and 27% of males. Most of the participants have come across the term stem cells and thought that only pulp stem cells signified the only source of dental stem cells. The majority of the participants pointed out the anticipated high cost to be the biggest obstacle to a patient accepting regenerative dental treatment by stem cells. Conclusion This study reveals a good level of knowledge among dental professionals, and it also showed the need to develop more awareness about the advancements in applications and banking.
