The novel coronavirus causing severe acute respiratory syndrome (SARS-CoV-2) induced a pandemic influencing several countries worldwide; it has also caused serious concerns in dentistry due to its routes of transmission. As compared to the beginning of dental operations, the total microbial load suspended in the air rises more than three times during dental procedures due to the aerosols contained in the saliva, blood, organic tooth particles, bacteria, or viruses. Various types of dental lasers are recognized to be already produced and used in the treatment of hard and soft dental and oral tissues. One of the benefits of the dental laser is its ability to decontaminate surfaces and destroy germs. Dental lasers produce substantially less aerosols and droplets in comparison to high-speed dental headpieces and ultrasonic devices. Therefore, it is beneficial to indicate its influence in reducing the COVID-19 contamination risk, especially in dentistry.

Recent studies have reported the connection between increased risk of cardiovascular diseases and diabetes with the presence of chronic periodontitis. The aim of this study was to determine the relationship between chronic periodontitis and triglyceride, high-and low-density lipoprotein (HDL and LDL), and glucose levels. Materials and methods: A total of 102 individuals participated in this comparative case-control study and were divided into a test group (51 people with chronic periodontitis with at least two periodontal pockets of >5 mm depth) and a control group (individuals with healthy periodontium or gingivitis). Plasma lipid levels and blood glucose were measured, and the data were statistically analyzed using chi-square and t-tests at p < 0.05 with SPSS version 21. Results: A significant increase in serum triglyceride, cholesterol, and glucose (p < 0.0001) was observed in the test group (group I), whereas serum HDL and LDL showed no significant increase in the test group (group I) compared to the control group (group II) (p = 0.244 and p = 0.127, respectively). Conclusion: This study suggested a connection between hyperglycemia and hyperlipidemia with chronic periodontitis, however, the etiology could not be precisely determined.
