Needlestick and sharp instrument injuries are common in dental practice and present the risk of direct exposure to blood-borne pathogens, including hepatitis B virus. This cross-sectional study was carried out to determine the risk factors of injury and infection in three types of dental clinic in Riyadh, Saudi Arabia. A total of 274 male and 241 female dentists completed a structured questionnaire on demographic factors, compliance with infection control practices, and past exposure to injury and infection hazards. Dentists with more years of professional experience were significantly less likely to report having had an injury in the past (unadjusted odds ratios (ORs) and 95% confidence intervals (CIs) were 0.48, 0.27-0.87 and 0.38, 0.16-0.89 for dentists with 10-20 years and for those with over 20 years of experience, respectively). Greater compliance with infection control procedures was associated with significantly fewer reports of previous infection (OR 0.31, 95% CI 0.12-0.84). Experience of occupational safety training was not associated with a lower rate of injury or infection. Greater occupational safety knowledge and compliance with infection control management practices contribute to a reduced risk of injury and infection among dentists. More focused and specialized training on infection control and occupational safety is needed for all practicing dentists and dental students.

Objectives Behaviour management strategies involving pharmacological or non-pharmacological interventions during dental procedures should be considered to attain safe and successful treatment outcomes. This study compared the frequencies of use and the completeness of treatment with these interventions. Methods A total of 1725 dental records of patients up to 18 years old, who were treated in the King Abdulaziz Medical City in Jeddah City from October 2018 to June 2019, were used in this retrospective, cross-sectional study. Inferential analysis, Chi-square test, Kruskal–Wallis test, and regression model were used in the data analysis. Results About two-thirds of the patients were treated with attendant non-pharmacological interventions, while one-third, with pharmacological interventions. The application of General Anesthesia (GA) was the most frequently used intervention. Restorative procedures and extractions were done in higher frequencies with pharmacological interventions. Treatments with space maintainers and orthodontic appliances were carried out in higher frequencies with non-pharmacological strategies. The choice of intervention was significantly influenced by the systemic conditions of the patients. Patients treated with non-pharmacological intervention comprised the dominant type of patients, because they required treatments with less pain. Those treated with GA needed restorative treatments and extractions, or treatments that involve pain, but these treatments had higher frequencies of being completed. Conclusions The treatments with pharmacological intervention through GA have higher frequencies of being completed, compared to those with non-pharmacological interventions. Factors, such as age, potential to complete the treatment, and the type of dental treatment applied, influence the choice of treatment intervention.

This study assessed the nature, prevalence, and risk factors of musculoskeletal symptoms (MS) in dental clinics. A self-administered questionnaire was completed by 515 dental students and dentists about nature of work and prevalence and frequency of MS symptoms. Chi-square and logistic regression were used to determine the association of MS with a number of important variables. Pain in the lower back (64%) and neck (60%) were the most prevalent MS. Working in the dental colleges' clinics was associated with increased risk of MS (adjusted OR 2.30, 95% CI [1.27, 4.18]). A stronger association was observed for dentists working in the private clinics (adjusted OR 2.58, 95% CI [1.28, 5.17]). Female dentists were at more risk of MS than male participants (OR 1.63, 95% CI [1.02, 2.59]). The higher risk of reported MS symptoms in women and for those working in the dental colleges and private clinics underscores the importance of recognition and prevention of MS symptoms even early in the dental profession.
