The dental community's awareness of implications of poor health within chronic renal failure patients should be elevated.

Endodontic and periodontal microsurgery has surpassed the success rates for traditional endodontic and periodontal surgical procedures. Excellent healing results are being attributed to both the techniques, when employed, for isolated endodontic or periodontal defects. Combined endodontic-periodontal lesions have been referred to as a true challenge, requiring not only endodontic microsurgical management but also concurrent bone grafting and membrane barriers techniques. The prevention of epithelial downgrowth and regeneration of periodontal cementum, fiber, and bone seals the fate of these cases. Achieving primary closure with submergence of grafts has a positive effect on GTR outcome. New techniques of periodontal microsurgery, such as minimally invasive papilla preserving flaps with passive internal mattress suturing, have managed to obtain 90% primary flap closure over grafted sites. Root surface treatment and conditioning has also shown to be beneficial for GTR. Endodontic microsurgery for the combined lesion has not integrated these advances yet. These advances, along with a recently suggested treatment strategy, are ushering in the level next in management of the combined lesions. This article offers an overview of the combined lesion, the disease, its classification, treatment strategy, regenerative tools, microsurgical recommendations, and outcome studies.

Background: Various conceptual hypotheses have been put forth to link association of COVID-19 with various chronic diseases such as periodontitis. Empirical evidence is still lacking to correlate the severity of COVID-19 with periodontal diseases. Objectives: This study was undertaken with an objective to correlate COVID severity in systemically healthy patients suffering from periodontal diseases. Materials and Methods: 44 systemically healthy patients of both genders with minimum of 20 teeth in their oral cavity in age range of 20 to 50 years suffering from periodontitis were recruited and categorised into four stages as per American Academy of Periodontology (AAP) 2017 classification for periodontitis. Serum C-reactive protein (CRP) levels and periodontal disease parameters of all the patients were measured. Because of COVID-19 and the nationwide lockdown, the dental practice was highly affected. With the help of self-designed online questionnaire information regarding COVID-19 infection and associated symptoms were recorded. Cases were categorized into five groups based on the World Health Organization clinical progression scale of COVID severity. Results: All the patients suffering from COVID disease in moderate and severe forms had increased probing pocket depth, clinical attachment level, and raised serum C-reactive protein levels as compared to patients who were uninfected or suffering from mild COVID disease and the results were statistically significant. Conclusion: Prioritisation and Implementation of periodontal treatment as a preventive measure for COVID-19 should be done. A positive correlation is observed between the severity of periodontitis and COVID-19.
