Evaluation of Comfort Levels of Patient and Ergonomics of the Dental Surgeon during Manual Scaling under Both Proprioceptive Derivative Concept and Conventional Approach: A Cross-sectional Study

Introduction: The important components that contribute to successful dental care are maximum accessibility, visibility, comfort, and control over clinical processes. Dental practitioners are more prone to developing musculoskeletal disorders due to awkward working postures. To minimise all these risk factors, a new concept called Proprioceptive Derivative (PD) has come into existence. Aim: The main aim of this study was to evaluate the comfort levels of the patient and ergonomics of the dental professional in the PD approach and conventional approach. Materials and Methods: A cross-sectional study was conducted in which manual scaling was performed by 20 dentists on 120 patients using the PD concept and conventional concept. A 13-item questionnaire was distributed among the patients and clinicians to record their perceptions of comfort levels, clinicians’ treatment satisfaction levels, and the time needed to complete the procedure after mastering the PD concept. In indepedent sample t-test was use to compare the responses among the two groups. p≤0.05 was considered statistically significant. Results: The comfort levels of the clinician (q1) during treatment in the conventional approach, with a mean value of 2.96±0.69, were significantly lower than in the PD approach, with a mean value of 3.46±0.85 (p<0.001). However, from the perspective of the patients, the mean comfort levels using the conventional strategy were 2.61±1.03, while using the PD approach, it was 2.85±1.11, which was not statistically significant (p>0.05). Conclusion: The clinicians had more ergonomic benefits and improved time factors under the PD concept. By following the work postures according to the PD concept, clinicians can avoid musculoskeletal discomfort, which is beneficial to all clinicians and can increase the longevity of their clinical practice
