The association between restorative pre-clinical activities and musculoskeletal disorders

Objective: To evaluate the risk of development of musculoskeletal disorders in the upper limbs of undergraduate dentistry students during the execution of pre-clinical laboratory activities based on gender, type of dental procedure and area of the mouth under treatment.Methods: Male and female undergraduate students in the second year of the Araraquara Dental School, UNESP, were enrolled in this study. Digital photographs were obtained whilst the subjects performed laboratory activities. The working postures adopted by each student were evaluated using the Rapid Upper Limb Assessment (RULA). The photos were analysed by a calibrated researcher (k = 0.89), and a final risk score was attributed to each analysed procedure (n = 354). Descriptive statistical analyses were performed, and the associations of interest were analysed by the chisquare test (P = 0.05).Results: During most of the laboratory procedures performed, the risk of developing musculoskeletal disorders was high (64.7%; - IC95%: 59.7-69.7%), with no significant association between the RULA final score and gender (chi(2) = 1.100; P = 0.577), type of dental procedure (chi(2) = 5.447, P = 0.244) and mouth area treated (chi(2) = 4.150; P = 0.126).Conclusions: The risk of developing musculoskeletal disorders was high in undergraduate dentistry students; this risk was not related to gender, type of dental procedure and region of the mouth being treated.

A survey of the management of patients with temporomandibular disorders by general dental practitioners in southern Brazil

Purpose: Temporomandibular disorders (TMD) are recognized as one of the mostcontroversial topics in dentistry, despite the fact that both basic science and clinicalresearchers have currently reached some degree of consensus. This study aimed toconduct a questionnaire-based survey about the management of TMD patients bygeneral dental practitioners (GDPs).Materials and Methods: One hundred fifty-one GDPs with a private practice in a cityof southern Brazil were included, independent of school of origin, gender, graduationyear, and curriculum content. All participants were administered a questionnaire aboutthe management of patients with TMD, and the responses were analyzed by binomialand chi-square tests (α = 0.05).Results: Of the GDPs, 88.7% received TMD patients, who were primarily diagnosedon the basis of medical history (36.6%) or physical examination (30.4%). Of these,65.4% referred the patients elsewhere, primarily to specialists in occlusion (36.1%) ororthodontics (29.7%). Occlusal splinting was the most commonly used managementmodality (20.8%), followed by occlusal adjustment (18.1%) and pharmacotherapy(16.6%). Splints were fabricated in maximum habitual intercuspation or centric re-lation depending on individual patient (54.8%). The hard stabilization form was themost common type of appliance used (35.0%). Moreover, 73.8% of the GDPs didnot employ semi-adjustable articulators, and 69.5% adjusted the appliances at thetime of fixing. The duration of splint use and the frequency of follow-up were con-sidered patient dependent by 62.1% and 72.8%, respectively. GDPs considered thetwo major TMD etiologic categories as multifactorial (20.8%) and occlusion (19.9%).Multidisciplinary medical and dental treatment was considered necessary by 97.9%.Conclusions: The evaluated general dental practitioners manage TMD patients ac-cording to international guidelines.

Musculoskeletal disorders in upper limbs in dental students: exposure level to risk factors

Aim: This study assessed the risk factors of undergraduate students to develop musculoskeletal disorders (MSD) in the upper limbs, regarding gender, type of dental clinical procedure, mouth region treated, and the four-handed dentistry practice. Methods: Dental students enrolled in the 8th semester in the Araraquara School of Dentistry, UNESP, Brazil, were photographed while practicing 283 dental procedures. The Rapid Upper Limb Assessment (RULA) method was used to evaluate the working postures of each student. The photographs were evaluated and a final risk score was attributed to each analyzed procedure. The prevalence of risk factors of developing MSD was estimated by point and by 95% confidence interval. The association between the risk factor of developing disorders and variables of interest were assessed by the chi-square test with a significance level of 5%. Results: The risk factors of developing MSD were high, regarding most dental procedures performed by the undergraduate students (score 5: 7.07%, CI95%: 4.08- 10.06%; score 6: 62.54%, CI95%: 56.90-68.18%). There was no significant association between the RULA final score and gender (p=0.559), and type of dental procedure (p=0.205), and mouth regions by arch (p=0.110) or hemi-arch (p=0.560), and the use of four-handed dentistry (p=0.366). Conclusions: It can be concluded that gender, type of dental clinical procedure, mouth region treated, and practice of four-handed dentistry did not influence the risk of developing MSD in the upper limbs among the dental students evaluated; however, they are at a high risk of developing such disorders.

Risk muskuloskeletal disorders in upper limbs in dental students: concordance of different methods for estimation of body angle

The purpose of this paper was to evaluate the agreement among different methods used to estimate angular deviation of the body to determine the risk for development of upper limb musculoskeletal disorders in dentistry undergraduates. Materials and Methods: Students (n = 79) enrolled in the final year undergraduate course of the Araraquara School of Dentistry-Sγo Paulo State University-UNESP were evaluated. Photographs were taken of students performing clinical procedures. The work postures adopted by each student were evaluated by means of rapid upper limb assessment (RULA). The basis used to obtain the individual's final risk score is the measurement of the angular deviations in the neutral positions of the regions evaluated. Two methods were used to estimate the angular deviation of the body: Visual exam and Image Tool software. A RULA final risk score was attributed to each procedure the student performed (n = 333). Study of the agreement between the methods about risk of musculoskeletal disorders was conducted by means of Kappa (κ) statistics. The level of significance adopted was 5%. Results: Fair agreement (κ = 0.32) between the evaluated methods was verified. Conclusion: The risk for development of upper limb musculoskeletal disorders by dentistry undergraduates evaluated by using RULA was not in agreement with the results obtained by use of visual exam and Image Tool.

Perception of Risk of Musculoskeletal Disorders Among Brazilian Dental Students

The aim of this study was to compare the mean scores of perceived risk factors for the development of musculoskeletal disorders in dental students presently pursuing work/study, according to gender, course series, and the presence of pain/discomfort. The participants were 348 students from the undergraduate course in dentistry at a Brazilian public university. The instrument on work-related factors that could contribute to osteomuscular symptoms and part of the Nordic questionnaire were used. The psychometric properties of the first instrument were estimated. A multivariate analysis of variance (MANOVA) revealed that the instrument had a tri-factorial structure (s2 retained: 62.72 percent). The retained factors were repetitiveness, work posture, and external factors. The internal consistency and reproducibility were adequate (α=0.746 to 0.873; p=0.729 to 0.940). Lower mean scores of perceived external factors were observed for the male participants, as well as lower scores in the three dimensions of the instrument for first-year students of the course and for those who did not report pain/discomfort in the neck, feet, and ankles. The authors concluded that the perception of risk factors for musculoskeletal disorders reported in the work/study environment of dental students was significantly related to gender, the course series, and the presence of pain/discomfort.

A perspective on the proposal for neurocognitive disorder criteria in DSM-5 as applied to HIV-associated neurocognitive disorders

HIV-associated neurocognitive disorders remain common in the current era of effective antiretroviral therapy. However, the severity at presentation of these disorders has been reduced, and the typical manifestations have changed. A revision of the American Academy of Neurology (AAN) criteria has been made on this basis, and a revision of the analogous criteria by the American Psychiatric Association will be forthcoming in the Diagnostic and Statistical Manual of Mental Disorders (DSM)-5. This article compares the relevant sets of diagnostic criteria that will be employed. It is concluded that a greater degree of integration of the revised, HIV-specific AAN criteria for HIV-associated neurocognitive disorders with the criteria proposed for the DSM-5 would prove advantageous for research, clinical, educational and administrative purposes.
