“…Musculoskeletal disorders are the most common and debilitating disorders associated with dental practice ( Dable et al, 2014 ; Plessas & Bernardes Delgado, 2018 ; Hayes et al, 2021 ; Pazos et al, 2022 ). They consist of injuries that occur in muscles, tendons, nerves, vessels, joints, and the entire musculoskeletal system ( Graça, Araújo & Silva, 2006 ), thereby causing severe pain and loss of efficiency and accuracy in clinical practice ( Hoerler et al, 2012 ). In extreme cases, due to the resulting level of disability, these disorders can cause abandonment of professional careers ( Garcia et al, 2012 ).…”

Objectives This study aimed to observe the effect of different finger rest positions on the muscular activity of the hand, forearm, arm, shoulder, thorax, and neck, as well as on the angular deviation from the neutral position of the neck, trunk, upper arm, and forearm on the working side during pre-clinical procedures. Methods An experimental laboratory study was performed. Response variables were muscle activation of the abductor pollicis, brachioradialis, biceps brachii, deltoid, pectoralis major, and right sternocleidomastoid muscles and angular deviation from the neutral position of the neck, trunk, arm, and forearm during simulated clinical procedures. Independent variable was finger-rest position during cavity preparation (no finger rest, usual rest, and ergonomic rest). Class I cavity preparations (N = 120) were performed on artificial first molars (16, 26, 36, and 46) (N = 120). Muscular activation was assessed by surface electromyography and angular deviations using Software for Postural Assessment (SAPO) version 0.69. One-way analysis of variance and Tukey’s or Games-Howell’s post-hoc tests were performed (α = 0.05). Results For the sternocleidomastoid muscle, there was no statistically significant difference between the different rest positions. For the deltoid muscle, work with no finger rest resulted in greater muscle activation (p < 0.001) during work on tooth 36. Regarding the pectoralis major and right brachioradialis muscles, we observed that for both teeth 16 and 26, working with ergonomic rest showed less muscle activation. Muscle activation of the right biceps brachii was higher for work with no rest in both the upper and lower arches, differing significantly only from the usual rest in tooth 16 (p < 0.001), usual rest and ergonomic rest in teeth 26 and 46 (p < 0.001), and only ergonomic rest in tooth 36 (p = 0.044). In the right abductor pollicis muscle, work with ergonomic rest resulted in less muscle activation for cavity preparation in teeth 16, 26, and 36, which was significantly different from work with no rest (p = 0.029, p < 0.001, and p = 0.013, respectively). Regarding angular deviation, it was observed that for tooth 16, there was a greater angular deviation of the arm when performing cavity preparations with no finger rest. For teeth 26 and 46, the ergonomic finger rest provided lower angular deviation from the neutral position of the right arm. For tooth 36, ergonomic rest provided less angular deviation from the neutral neck position. Conclusion In general, the use of non-active finger rest during simulated cavity preparations, regardless of the type of rest, provided less muscle activation and angular deviation from the neutral position of the body’s upper extremity when performing pre-clinical procedures.

“…As a result, their visualization of and access to oral structures are compromised ( Presoto & Garcia, 2016 ; Presoto, Wajngarten & Garcia, 2016 ). Because this visibility is of extreme importance for dental treatment ( Perrin, Jacky & Hotz, 2000 ), professionals often instinctively move closer to patients in an attempt to improve visualization of the anatomical structures of the oral cavity ( Graça, Araújo & SIlva, 2006 ; Keinan, Nuni & Slutzky-Goldberg, 2009 ; De Jesus Júnior & Campos, 2014 ). Because of this focus on the procedure, both dental students and professionals find themselves disregarding their working posture.…”

Objectives This study observed the effect of different magnification systems on working posture and neck angulation during cavity preparation procedures according to operator’s experience. Methods This was a laboratory study. The response variables were the neck angulation and the working posture adopted during Class I cavity preparations (N = 640) that were performed under four conditions (unaided visualization, simple loupe, Galilean loupe and Keplerian loupe). Working postures were recorded and evaluated by the Compliance Assessment of Dental Ergonomic Posture Requirements (CADEP). The two-factor ANOVA and Games-Howell post-hoc test were performed (α = 0.05). Results For all treated teeth it was observed higher posture scores and lowest neck angulations while using the Galilean and Keplerian loupes (p < 0.01). No correlations were found between operator’s experience and working posture (p = 0.71–0.88). Conclusion It can be concluded that Galilean and Keplerian loupes helped operators to maintain an ergonomic posture and lower neck angulations for all teeth and the operator’s experience provided better ergonomic posture for the mandibular teeth.

Disorders localized to the musculoskeletal system are a common problem among dental personnel. This study has the aim of surveying epidemiological studies reporting positive associations between dental practice and musculoskeletal disorders (MSKDs). The focus was to evaluate the size of reported risk increase and the extent to what alternative causal explanations were considered. Reports with significant links (p value <.05) were systematically selected from 2 electronic databases. Twenty-five studies were identified. Risk measures were reported in 8 studies, and all of them presented weak associations. The impact of at least 1 competing explanations was analyzed in 32% of studies, but adjustment was considered not adequate in half of them. The evidence on dentistry as a profession with potential risk for development of MSKDs remains questionable. Further research is needed to more carefully elucidate the risk and the impact of MSKDs in this particular occupational group.
