Objectives: Musculoskeletal disorders (MSDs) compose a large part of occupational diseases in dental professionals, prevention of which is dependent on assessment and improvement of job postures by means of ergonomic interventions. This study was aimed at evaluation of ergonomic conditions of the profession of dentists and also at assessing the relationship between MSDs and conditions of work. Materials and Methods: This cross-sectional study was performed among 65 dentists using the method of Rapid Entire Body Assessment (REBA). The prevalence of MSDs was obtained by the use of the Nordic Musculoskeletal Questionnaire (NMQ). Results: In this investigation, the prevalence of MSDs for different body parts was: 75.9% for the neck, 58.6% for the shoulders, 56.9% for the upper back, 48.3% for the lower back and 44.8% for the wrist. Job analysis by the use of REBA showed that 89.6% of limbs in group A and 79.3% of limbs in group B had a score > 4. Only neck and lower back pain have significant relationship with the risk levels obtained using the REBA method. Conclusions: It can be concluded that work postures of dentists need to be improved. In addition to education, work station design, rest period during work and regular physical activities should be taken into account.

Objectives Health care workers, including dentists, are at the front line for acquiring blood-borne virus infections. This study aimed to investigate the prevalence of hepatitis B, hepatitis C and human immunodeficiency viruses among Iranian dentists. Material and Methods The survey included 1628 dental health care workers who attended the 51st annual Congress of the Iranian Dental Association. Data on the risk of blood-borne virus transmission during health care and infection control practices were gathered from self-administered questionnaires. Sera were screened serologically by enzyme-linked immunosorbent assay (ELISA). The positive samples were examined by polymerase chain reaction (PRC) followed by direct sequencing. Results Six (0.36%) and 81 (5.0%) were positive for hepatitis B surface antigen (HBsAg) and (anti-hepatitis B virus core antigen (anti-HBc), respectively. Only 1 (0.061%) was positive for anti-hepatitis C virus (anti-HCV). No case was positive for anti-human immunodeficiency virus (anti-HIV). One case was diagnosed as being occult hepatitis B virus (HBV) infection. One thousand five hundred thirty-five (94.3%) of participants had received at least 1 dose of HBV vaccine. One thousand three hundred fifty-nine (88.5%) contained hepatitis B surface antibody (anti-HBs) > 10 IU/ml, of whom 55 (4.0%) were anti-HBc positive, suggesting that they had been infected with HBV in the past. Anti-HBc positive cases had past histories of hepatitis, either their own or their spouses’. Individuals with inadequate anti-HBs levels (< 10 IU/ml) were significantly more prevalent among anti-HBc positive cases (p < 0.001). Conclusions The prevalence of blood-borne viruses among dental HCWs found in this study was lower than past reports from Iranian dentists and general population. The implementation of HBV vaccination together with improvement in infection control procedures has reduced the potential for risk infection among Iranian dentists.

Objectives To investigate the prevalence of work-related musculoskeletal disorders amongst dentists who work in public clinics in São Paulo, Brazil, to investigate their awareness of the presence of risk factors in the workplace, disability due to pain, and the influence of pain on this awareness and disability. Material and Methods A cross-sectional study was conducted among 204 dentists who work in public health clinics in the northwest of São Paulo, Brazil. The data was collected through interviews, using the Nordic Questionnaire and the Work-Related Activities that May Contribute to Job-Related Pain Questionnaire. In the case of workers who reported pain, the Pain Disability Questionnaire (PDQ) and the Numeric Pain Scale were also administered. Statistical analyses were performed using SPSS 21.0. Results Most dentists (81.4%) had musculoskeletal disorders, especially in the neck, shoulders and lower back. We found that the presence of symptoms in the neck (15.7%), shoulders (12.7%) and lower back (15.7%) were the major causes of absenteeism over the past 12 months. Occupational risk factors perceived as the most problematic ones were: bending or twisting the back in an awkward way, continuing to work when injured or hurt and working in the same position for long periods. Comparison between the symptomatic and asymptomatic dentists showed a statistically significant difference (p < 0.05) in the perception of occupational risk factors. The analysis of the intensity of pain and disability with PDQ in the symptomatic dentists showed an average pain intensity of 3.8. Mean scores of the PDQ total (11.46) and its dimensions – functional condition (7.1) and psychosocial condition (4.4) – suggest a moderate disability in the dental surgeons. There was a strong t correlation (r = 0.697) between pain intensity and the total score of disability caused by pain. Conclusions Pain and work-related musculoskeletal disorders interfere significantly with the dentists’ lives. In the case of dental surgeons there is a significant correlation between pain intensity and disability. Int J Occup Med Environ Health 2017;30(3):367–377

Objectives Local anesthetics are some of the most common drugs used in dentistry and about 6 million people daily around the world are subjected to their effect in procedures performed by a similar number of dentists who, in turn, are usually not aware of the fact of being allergic to this group of medications. Assuming that dentists are also patients, and that in their daily practice the contact with the allergen is very frequent, it is essential to assess the incidence of allergy to lidocaine in general dental practitioners. Material and Methods The authors evaluated a group of 100 general dental practitioners in whom adverse reactions similar to anaphylaxis occurred after local anesthesia. The study included individuals who, in their thorough medical history, had experienced episodes of such reactions regarding the skin, airways, gastrointestinal tract and other areas. Results The relations between type I hypersensitivity and certain symptoms, time from exposure to their appearance, as well as time from the last episode were investigated. Allergy to lidocaine was detected in 17 subjects – type I hypersensitivity was diagnosed in 13 cases (skin prick test – 7; intradermic test – 6) and 4 subjects had IgE-independent allergy (patch test). In the group where type I hypersensitivity was detected, urticaria, angioedema and rhinitis were indicated as inclusion criteria more often than among other subjects. According to the results, the occurrence of angioedema increased the risk of detection of type I hypersensitivity 68.8 times, and 1 year longer period from the last episode decreased this risk by circa 55%. Conclusions The most important, from the clinical practice point of view, was to show the relation between the medical history indicating the anaphylactic nature of the lidocaine intolerance, and an allergy confirmed by skin tests.
