Gingival Depigmentation by Application of Diode Laser at 810 nm (Denlase) and 470 nm (Bluelase) Wavelengths: A Split-mouth Randomised Clinical Trial

Introduction: Gingival hyperpigmentation is a common aesthetic concern that often requires treatment to achieve a pleasing smile. While various methods for depigmentation have been described in the literature, the scalpel method is widely advocated. Laser technology, particularly diode lasers, has emerged as a preferred treatment option due to their unique properties. Aim: To compare the efficacy of two different diode wavelengths, namely Denlase and Bluelase lasers, in terms of pain intensity, aesthetic appraisal, and the rate of repigmentation. Materials and Methods: This split-mouth randomised clinical trial was conducted in the Department of Periodontics at Vishnu Dental College, Bhimavarm, Andhra Pradesh, India. over a period of one year with follow-up. A total of 16 patients were included, and the right and left quadrants (both maxilla and mandible) were randomly assigned to either the Denlase or Bluelase group using the coin toss method. Depigmentation using diode lasers at 810 nm and 470 nm wavelengths was carried out in the respective groups. Pain perception, aesthetic appraisal, and recurrence of pigmentation were evaluated at 1, 3, 6, 9 months, and one year. The data were analysed using Friedman’s analysis and the Mann-Whitney U-test. Results: A total of 16 subjects, with a mean age of 27.64±7.64 years and of both genders, were included in the study. Statistically significant differences (p=0.001) were reported in pain perception, aesthetic appraisal, and the rate of repigmentation at 1, 3, 6, 9 months, and one year, respectively. Intergroup comparison revealed an increase in the mean amount of repigmentation at three months in the Denlase group, indicating a recurrence of pigmentation after three months. Conclusion: The Bluelase diode laser (470 nm) demonstrated superior results compared to the Denlase diode laser (810 nm) in terms of pain intensity, aesthetic appraisal, and repigmentation

Knowledge, attitude, and practice of teledentistry in periodontal diagnosis: Is it the required upgrade to conventional periodontics?

Background: Teledentistry which is similar to telemedicine has emerged as a new tool for various dental disciplines. Teleperiodontics is a branch of telehealth which focuses on the application of digital communication technology into the field of periodontics without demanding a specialist presence. An early detection and diagnosis of periodontal conditions can not only treat the disease in its early stage but also prolong the health of the periodontium, thereby improving the overall quality of life of an individual. However, teledentistry has not penetrated into the field of periodontics to a level it has to in providing periodontal care. Hence, the aim of this questionnaire study was to assess the knowledge, attitude, and application of teleperiodontics into everyday practice among the dental surgeons at various levels. Materials and Methods: An electronic questionnaire consisting of 29 close-ended questions including sections assessing the knowledge, attitude, and practice of teledentistry and teleperiodontics was sent to dental colleges present in East and West Godavari districts of Andhra Pradesh. Results: A total of 350 responses were received and 80.57% dental surgeons were aware about teledentistry, and a total of 74% dental surgeons were likely to prescribe oral hygiene aids and medication for temporary management of periodontal conditions. Conclusion: Teleperiodontics is an emerging science whose knowledge, attitude, and application are yet to be explored

Treatment of Dentinal Hypersensitivity with Diode Laser of Two Different Wavelengths- A Randomised Clinical Trial

Introduction: Dentinal Hypersensitivity (DH) is one of the most prevalent dental issues that is treated by both periodontists and endodontists. Hypersensitive dentin is a sensitive or painful response that is one of the most prevalent and poorly treated chronic dental disorders. Due to the difficulty in treating cervical DH, a great range of approaches and therapeutic procedures for pain relief in have developed. Treatments with desensitising drugs have been combined with laser treatment in recent decades. The most often utilised lasers in the treatment of DH are Diode Lasers (DL). DL act on DH provoking a melting effect with crystallisation of dentine inorganic component and the coagulation of fluids contained into the dentinal tubules. Aim: To compare the effectiveness of DL of two different wavelengths in managing DH. Materials and Methods: This split-mouth randomised clinical trial conducted in the Department of Periodontology at Vishnu Dental College, Bhimavaram, Andhra Pradesh, India. The duration of the study was, from October 2021 to December 2021. A total of 12 patients with DH were selected and assigned to two groups. All the patients were subjected to desensitisation using DL of two different wavelengths 475 nm Bluelase system and 810 nm. Denlase system and parameters were evaluated 15 minutes after treatment, 7 days, 15 days and 30 days after treatment. Data were entered in Microsoft Excel and analysed using Statitical Package for Social Sciences (SPSS) version 10.5 software. Results: The mean age of the study participants was 45±3 years. There was a significant difference (p-value <0.001) in tooth sensitivity values measured at baseline, and at different time intervals in both groups. Among the two groups, Denlase group showed the greatest reduction in Visual Analogue Scale (VAS) scores from baseline to one month recall compared to Bluelase laser group. Highly significant difference was found when mean VAS scores were compared between baseline and all the other time points (p-value <0.001). Conclusion: The present study concluded that, based on the results obtained, DL of 810 nm Denlase system was effective than DL of 475 nm Bluelase system in reducing the DH. Desensitisation treatment with laser irradiation has shown to be effective in the present study

Knowledge, attitude, and practice of oral hygiene aids and its role in the prevention of COVID-19 transmission: A hospital-based questionnaire study

Introduction: The novel coronavirus disease has brought to the forefront the importance of oral hygiene aids and its role in the prevention of COVID-19 transmission. Objectives: The objective is to assess knowledge, attitude, and practice of oral hygiene aids and its role in COVID-19 transmission. Materials and Methods: This was a cross-sectional study conducted on 385 patients visiting Vishnu dental college. The questionnaire included demographic data, history of COVID, and vaccination status. The second part included questions regarding knowledge, attitude, and practice of oral hygiene aids and its role in COVID-19 transmission. Results: Mean age of the population was 40.11 years, and had almost equal proportions of males and females. About 22.6% of the population had suffered from COVID-19 and 92.7% of men got fully vaccinated. Knowledge of COVID-19 transmission through oral hygiene aids was found in 57.4% of the population. No difference in knowledge of occupational health advisor (OHA) and its role in COVID transmission was found between gender, COVID, and vaccination status (P > 0.05). About 22.9% of graduates had higher knowledge than others (P = 0.00). Conclusions: The use of appropriate oral hygiene aids and practices could prevent the transmission of COVID-19
