ABSTRACT Aim The aim of this study was to define the prevalence and severity of temporomandibular disorders (TMD) among Iranian dental and nondental students who attended Shiraz University of Medical Sciences. Materials and methods The samples consisted of 200 subjects, 100 dental and 100 nondental students (equal distribution between males and females). Subjects ages ranged from 18 to 30 years (24.07 ± 2.93). A functional evaluation was performed using the Helkimo dysfunction index (Di). Data were evaluated by the Chi-square test. Results Among the total study population, 71% showed some degree of dysfunction. Prevalence ratio in dental students was 80%, while in nondental students was 62% (p < 0.05, odds ratio = 0.679). With respect to gender, women (80%) were more affected than men (62%). A significant relationship was found between gender and the occurrence of TMD (p < 0.05). Conclusion A high prevalence of signs of TMD in Iranian university students was seen which was greater in dental students and women. Clinical significance The results of this study showed that the prevalence of TMD among dental students and women was significantly higher than nondental students and men. These findings might be due to poor postural style or emotional stress during dental practice. How to cite this article Bahrani F, Ghadiri P, Vojdani M.

The scope of this study was to correlate toothache with social and economic conditions, access to oral health facilities and the lifestyle of adolescents in Sobral in the state of Ceará. It was conducted as a cross-sectional analytical study with a sample composed of 688 adolescents. The prevalence of toothache in the study group was 31.8%. A chi-square test of association was performed to measure the relationship between independent variables and toothache, estimating the prevalence ratio by Poisson regression. The factors that demonstrated the closest relationship with toothache were cavity severity, the reason for dental treatment being related to urgency, frequency of dental appointments and the distribution of toothbrushes at school. It was observed that the high prevalence of dental pain in adolescents is directly linked to the access conditions, as well as the characteristics of the actions developed by the health services. Just as there is a need for the deployment of services related to health promotion, based on equity and integration, it is necessary to introduce emergency services to intervene not just to curtail crippling pain, but also as a mechanism to stimulate the development of procedures for the prevention of oral diseases.

Abstract Objective: To estimate the prevalence of back pain in adolescent girls, and determine whether this pain is associated with socioeconomic, demographic, anthropometric, and behavioral factors. Methods: This was an epidemiological survey with a representative sample of 495 female high school students, aged 14 to 18 years, in the municipality of São Leopoldo in the southern Brazilian state of Rio Grande do Sul. Data were collected through a self-administered questionnaire with closed, standardized, coded, and tested questions. Bivariate analysis included the chi-square test (x2) and calculation of prevalence ratios (α<0.05). Results: The prevalence of back pain was 75.2%. The thoracic-lumbar (30.4%) and lumbar (27.7%) regions of the spine were most affected. Among the students with pain, 60.5% reported the severity of their pain to be moderate to severe, and 21.2% reported that the pain prevented them from performing activities of daily living. Regarding associated factors, the pain was more prevalent in overweight/obese students (RP = 1.246, 95% CI: 1.137 to 1.366), who reported carrying a heavy school backpack/bag (PR = 1.187, 95% CI: 1.073 to 1.314) and those who had incorrect posture when picking up objects from the floor (PR = 1.138, 95% CI: 1.031 to 1.256). Conclusions: There was a high prevalence of back pain associated with body mass index, reported weight of the student's school backpack/bag, and posture when picking up objects from the floor.

The Difference

: An emergency can be encountered anytime and anywhere. Minimal knowledge about medical emergency and their etiology, primary protocol for management must be known to avoid potential consequences. Hence, the present study was undertaken to compare the knowledge, and ability to handle the medical emergencies among the dental students. A cross-sectional survey was conducted among 100 randomly selected dental students (post-graduate students and interns) comprising of two groups of students those who had underwent training and those who did not. The data obtained was analyzed using the SPSS for windows version 22.0 released 2013. Independent chi square test was used for comparison of responses and independent student t-test was used for the comparison of mean scores. The significance level was set at p&#60;0.001. : The average mean knowledge and ability score was 68% & 61.4% respectively among the participants. On further comparison of mean knowledge & ability scores between the participants with & without basic life support training, participants with BLS training showed better knowledge than those without training and the difference was statistically significant between the two groups (p&#60;0.001%). The study found deficiencies in the knowledge and ability of untrained graduates to deal with medical emergencies as compared to trained.

BACKGROUND: Ephelides are small hyperpigmented macules common in the skin, presenting as areas with increased melanin production. Ephelides are observed in genetically predisposed individuals, particularly fair-skinned people highly susceptible to sunburn. OBJECTIVES: This study aimed to determine the prevalence of lip and perioral ephelides in 362 beach workers in the city of Natal (Rio Grande do Norte) and to investigate potential associations with sociodemographic, occupational and general health. METHODS: For this purpose clinical tests were performed by calibrated examiners in the epidemiological area around the lips and the area bounded laterally by the nasolabial groove and at the bottom by the chin. A questionnaire was completed and assessed. The possible associations between sociodemographic variables, occupational and general health with the presence of lip and perioral ephelides were evaluated by chi-square test for a significance level of 5%. RESULTS: Approximately one third of the workers were affected by perioral ephelides (33.7%) and around a quarter of them by lip ephelides (24.0%). Gender was the only variable significantly associated with the presence of perioral ephelides (p = 0.002), unlike lip ephelides which proved to be significantly associated with habits (p = 0.036) and alcoholism (0.030). CONCLUSIONS: The prevalence of ephelides in lip and perioral region was high in the study population, with gender and certain habits associated with its occurrence.

Objective: To examine the prevalence of five oral streptococci species of severe early childhood caries (S-ECC) and caries-free (CF) groups. Study design: Supra gingival plaque samples were obtained from 198 Thai children with ages ranging from one to six years old. Eighty-seven subjects had no caries (dmft=0), and 111 had S-ECC. After DNA extraction, S. mutans, S. sobrinus, S. sanguinis, S. oralis, and S. gordonii were identified by standard PCR using species-specific primers. Statistical analysis determined the differences among prevalence rates of each species using Pearson chi-square test. The relationship among dmft score, age, sex and caries status within each group was analyzed by logistical regression (p ≤ 0.05). Results: Sex was not correlated with any of the species detected in both groups (mean age =3.09, mean±SD of dmft=11.04±7.89). S. mutans was found at greatest prevalence in both groups followed by S. oralis. S. gordonii was detected at a high prevalence, but S. sobrinus and S. sanguinis were lower in S-ECC when compared with those from the CF group. Conclusion: S. mutans was associated significantly with S-ECC (p ≤ 0.05). Caries prevalence was highest (56.5%) in subjects infected by S. mutans alone. S. sanguinis prevalence was higher in the CF group, but not statiscally different. Infection with MS did not show higher caries prevalence.

This study aimed to identify types and sites of body injury, location of injury occurrence, and the mechanism and severity of injuries in novice and advanced Brazilian jiu-jitsu (BJJ) athletes. One hundred and eight BJJ athletes took part in this study separated in two groups: advanced (n = 53) and novice (n = 55). Athletes answered a questionnaire concerning regions of injury, locality of occurrence, injury severity and mechanism. Chi square test and a logistic regression analysis were used with the level of significance set at p < 0.05. The main results showed that shoulders and knees were the most injury location reported by novice and advanced athletes. Novice athletes demonstrated higher prevalence of injuries during training sessions (54.5%), whereas advanced athletes reported more injuries during competitions (66.1%). Significant associations between novice and advanced athletes were observed for major joints (p < 0.05). The odds ratio of having injury was 70-87% less for novice versus advanced athletes for the major joints cited. We concluded that BJJ athletes demonstrate high prevalence of injury mainly at knee and shoulder. While risk of injury appeared less in novice, the advanced demonstrated higher number of injuries during competitions as a consequence of injured joint keys. By contrast, novice athletes reported higher number of injuries associated with training sessions as a consequence of overuse.

Background: Due to limitations in provision of prosthetic care in South Africa, a screening tool to select transfemoral prosthetic candidates has been implemented. Objective: To describe prosthetic services, use and mobility of people with transfemoral amputation, identified as prosthetic candidates through the Guidelines for Screening of Prosthetic Candidates: Lower Limb, and to identify variables that might influence prosthetic use and mobility. Design: Cross-sectional survey. Methods: The study population included all adults who received their first prosthesis from the Orthotic and Prosthetic Centre in the Western Cape between 1 June 2011 and 31 December 2014. Data were collected, with an adapted version of the Prosthetic Profile of the Amputee, from 43 participants, through telephonic interviews. Descriptive and inferential analysis, with the chi-square test, was done. Results: The majority of participants were older than 50 years (77%). Most participants (35; 81%) used their prosthesis; however, only 42% (18) used it daily. A significant association ( p = 0.000) was found between prosthetic rehabilitation and self-reported prosthetic walking distance. Less than half of participants received prosthetic rehabilitation and only 10 (30%) could walk 500 steps and more without resting. Conclusion: Participants used their prosthetic leg, but experienced limitations in frequency of wear and mobility. Clinical relevance Current findings showed that participants’ prosthetic mobility was curtailed. In less-resourced settings, carefully selecting prosthetic candidates may be necessary to provide access to services. Prosthetic provision is advised to be followed up with prosthetic rehabilitation for favourable mobility outcomes.
