COVID Infections Breakthrough Post-Vaccination: Systematic Review.

Introduction: Many new variants of the coronavirus are infecting the already vaccinated people. There have been reports of deaths also among the already vaccinated subjects. Hence, we conducted a systematic review and meta-analysis of the infection breakthrough after COVID vaccination. Materials and Methods: We piloted a review of the healthcare workers who completed the vaccination for COVID. The data were collected from the online resources for the breakthrough infections after vaccination. We then enumerated those subjects who had a breakthrough infection post-vaccination. The data collected were meta-analyzed for the incidence of the infection among the vaccinated individuals. Results: We observed that among nearly 2.3 lakh subjects, less than 3% were infected with the various new strains of the virus. The ratio of the breakthrough infection was different for the vaccinated (1.2%) and the partially vaccinated (3.2%) individuals with greater infection among the partially infected individuals. Discussion: The breakthrough infections are very low among vaccinated individuals and even lower among fully vaccinated individuals. Hence, vaccination is highly recommended to prevent the loss of life.

Evaluation of Soft-Tissue Grafting in Peri-implantitis - An Original Research.

Introduction: With the increased application of the implants for the restoration of the lost teeth, the peri-implantitis cases are seen on a rise. Hence, we conducted a study retrospectively to evaluate, among the peri-implantitis cases, the success of the soft-tissue grafting. Material and Methods: We piloted a retrospective study among 50 subjects of both genders who underwent the soft-tissue grafting for the treatment of the peri-implantitis of a total of 69 implants. The clinical parameters noted were at the baseline and at various years of follow-ups. The data of the clinical parameters were noted, and the data thus noted were compared deliberating P < 0.05 as significant. Results: Thin soft-tissue biotype was noted among all the subjects, with the increased width of the keratinized mucosa. Significant lowering of the probing depth, bleeding on probing, and the mobility of the tissue were noted. Conclusions: We can conclude that soft-tissue grafting Is a benificial method for the peri-implantitis treatment.
