001). Of the subjects, 96.6% showed a decrease in the count of bacteria in GCF after using a charcoal toothbrush. Only 3.3% of the subjects had the similar counts of bacteria in GCF after using the charcoal toothbrush.
 
  The study demonstrates that charcoal toothbrushes reduce bacterial contamination and the poor effects on oral health after 1 week of use.

The risk outweighs the benefits in these unprecedented times if proper screening and inactivation of blood products are not performed. Pathogen reduction technologies incorporate various modalities for the inactivation of blood products mainly related to blood transfusion. Oral surgical procedures and periodontal surgeries use platelet-rich fibrin for various regenerative procedures that amplify the prognosis positively. The use of blood products for various treatments could result in contamination, a factor which should be significant attention. The objective of this study was to review the role of pathogen reduction technology in inactivating pathogens in blood products and its use in oral and periodontal surgical procedures. The literature presented in the study is from original studies from a period of 2000 to 2020 which was sourced from Medline, PubMed, and Cochrane central databases. Relevant published papers and in-press papers that provided information were identified and selected. The studies presented have shown data related to implementation of pathogen reduction technologies in relation to the severe acute respiratory syndrome, Middle East respiratory syndrome, and its possible implementation in coronavirus disease-2019 (COVID-19). The paper reviews the various technologies offered and the possibility to eradicate pathogens found in routine blood products, used in oral and periodontal surgical procedures. In all probability, the use of pathogen reduction technology might offer a ray of light to contain the spread among dental treatment procedures.
  Dental implants are considered the best treatment option for replacement of missing teeth due to high survival rates and diverse applications. However, not all dental implant therapies are successful and some fail due to various biological and or/mechanical factors. The objective of this study was to systematically review primary studies that focus on the biomechanical properties of dental implants in order to determine which biomechanical properties are most important for success of dental implant therapy.
 
  An electronic database search was performed using MEDLINE (PubMed), EMBASE, Google Scholar, and CAB Abstracts. Six principal biomechanical properties were considered to prepare the search strategy for each database using key words and Boolean operators. Human and animal studies (observational studies, trials, and 
  studies) were included in this review. Human studies that were considered eligible needed to have subjects above 18 years who received permanent restorations after implant surgery and follormed better than the internal hex design.  https://www.selleckchem.com/btk.html  Higher rate of complications (porcelain chipping, de-cementation) was observed in the cantilever groups in studies.
 
  Biomechanical properties of implants like preload, torque, cantilever design, implant abutment design have profound effects on the survival rates of dental implants. With limiations, this review provides some important parameters to consider for successful implant therapy.

  The aim of this study was to comprehensively review the various biomaterials used as scaffolds, rates of biodegradability of natural, artificial and composite hybrid scaffolds, and the role of controlled biodegradability in tissue engineering.
 
  An electronic search for systematic review was conducted in PubMed/MEDLINE (www.ncbi.nlm.nih.gov), Cochrane (www.cochrane.org), Scopus (www.scopus.com) databases, and dental journals related to endodontics and pediatric dentistry to identify the research investigations associated with the degradation profiles, factors relating to degradation, rates of biodegradability and the role of controlled biodegradability of natural, artificial and composite scaffolds. A sample of 17 relevant studies and case reports were identified in our search of 100 using simple random sampling.
 
  Naturally derived scaffolds degrade at a much higher rate than artificial and composite scaffolds. The degradation profiles of composite scaffolds can be much better controlled than naturally derived scaffolds.
 
  Composite scaffolds are more favorable as compared to natural or artificial scaffolds, as it has superior mechanical properties, minimal immune response, and a controlled rate of degradation and consequent tissue regeneration.

Randomized controlled trials evaluating the efficacy of use of lignocaine with buprenorphine versus lignocaine for intra-oral procedures were included by searching multiple databases. Outcomes assessed were onset of the time of anesthesia in seconds, duration of postoperative analgesia, postoperative pain (maximal follow-up), the number of rescue analgesics required, and adverse events. The search strategy yielded 167 publications for the title and abstract screening out of which only two trials were included for full-text screening. There was considerable heterogeneity among the included studies with regards to the outcomes assessed. The need for rescue analgesics was the only outcome that was included for meta-analyses. Forest plot showed that lignocaine with buprenorphine compared to lignocaine showed a significantly lower requirement of rescue analgesics (-0.
