Worldwide prevalence of carpal tunnel syndrome among dental health care personnel - A systematic review and meta-analysis.

Background: Carpal Tunnel Syndrome (CTS) is one such common disorder among dental health care personnel caused due to the entrapment neuropathy of the median nerve in the carpal tunnel. We aimed to evaluate the pooled estimates of the CTS among dental healthcare personnel. Methods: We systematically reviewed the existing literature from six databases till January 1 st, 2022. Studies reported in English along with the prevalence of CTS or where prevalence could be calculated were included. Independent screening of title and abstracts, and the full text was done by two examiners. Information collected was authors, year of publication, geographic location, type of dental healthcare personnel, sample size, distribution of age, sex, CTS, method of diagnosis, and risk of bias. The random effect model was used to estimate the pooled estimates. Results: Thirty-seven studies yielded 38 estimates. A total of 17,152 dental health care personnel were included of which 2717 had CTS. The overall pooled prevalence of CTS among the included studies was 15%, with a high heterogeneity. Meta-analysis showed no significant difference in the pooled estimates of CTS between male and female dental healthcare personnel (OR: 0.73; 95% CI: 0.52 -1.02; I 2= 69.71). The pooled estimates among the dentist and dental auxiliaries were 20% and 10%, respectively. The pooled prevalence of CTS with self-reported measures, clinical examination and NCS were 21%, 13% and 8% respectively. Meta-regression showed that the prevalence estimates were significantly associated with publication year (coefficient: 0.006; 95% CI= 0.002-0.01). Conclusion: One out of seven dental health care personnel may be affected by CTS. No significant difference was seen in the prevalence of CTS between male and female dental healthcare personnel.

Dental practitioners' knowledge, attitudes, and practices of ergonomics - a cross-sectional web-based survey.

BACKGROUND AND AIM: Dentistry is a profession known to have many occupational hazards, including biomechanical, ergonomic, and work factors. We aimed to evaluate dental practitioners' knowledge, attitudes, and practices of ergonomics and to evaluate the significant differences with age, sex, educational qualification and clinical experience. METHODS: We conducted a cross-sectional multi-centric web-based survey among dental practitioners of south India. Dentists who were involved in clinical practice in India with a minimum of 1-year experience were invited to participate in this study. Information on demographics (age, sex, education) and years of practice of the dental practitioners was collected. Knowledge attitude and practice questionnaire was adapted from El Salamy et al. Results: The mean age of the participants was 30.57 (SD=6.95). More than half of the respondents were female (60.1%). Dental practitioners who were less than 28 years old (OR: 0.57), graduates (OR: -0.47), and clinical experience less than three years (OR: -0.53) had a higher probability of having poor or fair knowledge scores. Dental practitioners who were more than 28 years old had a significantly higher probability of positive attitudes (OR: 0.6) and good practices (OR: 0.54). Practitioners with a master's degree had a higher probability of good practices (OR: 1.92). Practitioners with more than three years of clinical experience had a higher likelihood of good practices (OR: 1.72; 95% CI: 1.03 - 2.9). CONCLUSIONS: Overall, we could conclude that dental professionals had predominantly fair to good knowledge, positive attitudes and a high proportion of bad practices.

Perception of Indian Dental Students to Pursue Higher Education Abroad during COVID-19

ABSTRACT Objective: To evaluate Indian dental students' perception of seeking international dental higher education during COVID-19. Material and Methods: We conducted an online survey among the dental students. A self-administered questionnaire was prepared, which had information on country choice, reasons for the decision to study abroad, measures to be taken by the foreign universities because of COVID-19, the application's status, current plan, and opinions on exploring other possibilities. Results: Four hundred students constituted the final sample, out of which the majority were females (69.3%). Most of the students were not sure about their status in the application process (63%). The current plan to study abroad remained uncertain for almost half of the students (50.2%). Concerning the status of the application process, a significantly higher number of female students were "not sure" and are still "searching colleges" (p<0.001). Similarly, a higher number of females were "uncertain" or "postponed" or "canceled" when compared to the males concerning the current plan to study abroad (p=0.001). Also, a significantly higher proportion of female students cited the study budget as the main deterrent for pursuing a career abroad and opined that "flexible study options" will help them get admissions post-COVID-19 (p=0.001 and 0.035). Conclusion: A substantial impact was perceived by Indian dental students concerning higher education abroad, more among females.

Anti-plaque and anti-gingivitis effect of Papain, Bromelain, Miswak and Neem containing dentifrice: A randomized controlled trial.

BACKGROUND: Patients undergoing fixed orthodontic therapy may have difficulty in maintaining a good oral hygiene due to the difficulty posed by the appliances in accessing such areas. This study aimed to compare anti-plaque and anti-gingivitis efficacy of dentifrice containing Papain, Bromelain, Miswak and Neem with a standard dentifrice among patient's undergoing fixed orthodontic treatment. MATERIAL AND METHODS: Single center, single blind, parallel arm, randomized controlled clinical trial with an allocation ratio of 1:1 was conducted. Evaluation of plaque and gingivitis was done using Williams modification of Silness and Loe Plaque Index (PI) for use in orthodontic subjects and Loe and Silness's Gingival Index (GI) at baseline and one month. RESULTS: Inter-group comparison showed there was significantly lower mean plaque index in test (0.88 ±0.05) than in control group (1.17 ±0.05) after adjusting for the baseline plaque index (p<0.001). Similarly, there was significantly lower mean gingival index in test (0.87 ±0.04) than in control group (1.14 ±0.04) after adjusting for the baseline gingival index (p<0.001). CONCLUSIONS: The efficacy of the test dentifrice in limiting plaque and gingivitis suggests that it can be used as a home based adjunct to clinical therapy in orthodontic patients. Key words:Bromelain, gingivitis, miswak, neem, papain, plaque.
