The aim of this study was to evaluate the prevalence of posterior crossbite among children whose pacifier-sucking habit persisted until different ages. Children aged 3 to 6 years were randomly selected from public preschools in São Paulo, SP, Brazil. Their mothers were asked to complete a questionnaire on non-nutritive sucking behaviors. The sample consisted of 366 children assigned to 2 groups: control (n = 96) and pacifier users (n = 270). Pacifier users were further assigned to 3 subgroups, according to the age of habit persistence: P1 - until 2 years of age; P2 - between 2 and 4 years of age; and P3 - between 4 and 6 years of age. One dentist assessed the children for occlusal relationships through clinical examination. Associations between the age interval of habit discontinuation and the prevalence of posterior crossbite were analyzed using the chi-square test (p < 0.05). The prevalence of posterior crossbite was significantly higher among pacifier users (20.4%), compared to control children (5.2%), p < 0.01. Unilateral posterior crossbite was more prevalent than bilateral crossbite among pacifier users (9.8% versus 3.6%). Functional posterior crossbites were diagnosed in 3.1% of the control children and 7% of the pacifier users. The frequencies of posterior crossbite were notably high for children in the 3 pacifier subgroups, P1, P2, and P3, corresponding to 17.2%, 16.9%, and 27.3%, respectively. The high prevalence of posterior crossbite may be associated with pacifier-sucking habits that persisted after 2 years of age.

OBJECTIVE: To assess the occurrence of bruxism in deciduous dentition and a potential association between the habit and the presence or absence of posterior crossbite. METHODS: A total of 940 patient files were assessed. They were gathered from the archives of University of São Paulo City - UNICID; however, 67 patient files were dismissed for not meeting the inclusion criteria. Therefore, 873 children, males and females, comprised the study sample. They were aged between 2-6 years old and came from six different public primary schools from the east of the city of São Paulo. Data were collected through questionnaires answered by parents/guardians and by clinical examinations carried out in the school environment in order to obtain the occlusal characteristics in the transverse direction. First, a descriptive statistical analysis of all variables was performed (age, sex, race, posterior crossbite, bruxism, headache and restless sleep); then, the samples were tested by means of chi-square test with significance level set at 0.05%. A logistic regression model was applied to identify the presence of bruxism. RESULTS: The prevalence of this parafunctional habit was of 28.8%, with 84.5% of patients showing no posterior crossbite. Regarding the association of bruxism with crossbite, significant results were not found. Children with restless sleep have 2.1 times more chances of developing bruxism, whereas children with headache have 1.5 more chances. CONCLUSION: Transverse plane of occlusion was not associated with the habit of bruxism.

Introduction: The prevalence of occlusal traits varies among various populations. Ethnic, genetic and environmental factors are the major contributors, with a role in the specific cause of malocclusion. The aim of this epidemiological study was to assess the prevalence of occlusal traits in the deciduous dentition of children of Kaski District,Nepal. Methods: A total of 506 children (251 girls, 255 boys), aged 3-5 years, were assessed. The occlusion examination was carried out by three examiners, in the school camps,community dental care centre and general health camps, utilizing a mouih mirror and probe. Intra investigator error was calculated using kappa statistics. The data were analyzed by the statistical program SPSS version 17 using the Chi-square test. Results: The present study studied occlusal traits of 506 children (251 girls, 255 boys), aged 3-5 years. The study result showed that bilateral mesial step seen in 40.3%,bilateral flush terminal plane in 33.5%, bilateral distal steps in 8.5%,mesial step one side and flush terminal other side in 12.7%,mesial step one side and distal step other side in 2.6%,flush terminal one side and distal step other side in 2.4%,anterior crossbite in 3%,posterior crossbite in 0.4% and non-spaced dentition in 20% children. Conclusions: Mesial step was the most prevalent followed by straight terminal plane and the distal terminal plane showed least prevalence. There were diverse traits for malocclusion. There was no significant difference(p>0.05) in occlusal traits between male and female children.  Keywords: crossbite; distal step; flush terminal plane; mesial step; occlusion.

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.

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.

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.

This study aimed to understand the epidemiology of the main gastrointestinal endoparasites affecting sheep raised in the municipality of Sena Madureira, Acre, Brazil. A total of 178 fecal samples were collected from sheep raised in an extensive system of 10 farms. The samples were grouped into lambs, ewe lambs, lambing ewes, ewes, and rams for laboratory analysis by the flotation technique for counting eggs per gram of feces (EGF), oocysts of Eimeria sp., and presence of eggs of Moniezia sp. The analyzed variables consisted of the prevalence of nematodes, cestodes, and coccidia and intensity of strongylid and coccidium infection by quantification (mean ± SE) of eggs and oocysts. Prevalence data were compared by the chi-square test and intensity of infection (mean ± SE) by the Scott-Knott test (SAEG 9.1), both with P < 0.05. The overall prevalence was 77.6%, reaching 64.15% for strongylids, 36.2% for coccidia, and 8.81% for cestodes (Moniezia sp.). Ewes had the lowest prevalence (52.5%), while lambs had a prevalence of 95.5%, not differing from the others (P < 0.05). The intensity of infection by nematodes showed that lambs had the highest EGF compared to ewes, with values of 1297±270 and 232±79, respectively. The categories lambing ewes, ewes, and rams presented an average EGF below what is indicated for treatment with drugs. The highest intensity of infection was observed for ewe lambs (5859±3648), exceeding acceptable rates. Sheep raised in Sena Madureira has a high prevalence for verminosis by strongylids and a low prevalence for coccidiosis and cestodiasis. Young animal categories present a high health risk for endoparasitoses, and management measures that collaborate with the prophylaxis and control of these diseases should be adopted.

Abstract Background: The high prevalence of early childhood caries (ECC) is widespread around the world, and oral health education (OHE) plays a vital role in preventing ECC. Numerous studies on ECC risk factor assessment have assisted us in enriching the content of OHE. The objective of this study was to further assess independent risk factors for ECC at different ages to provide evidence and insights for OHE.Methods: Children aged 3-5 years old (N=1301) in Shandong Province were enrolled in this cross-sectional study. Data about oral health status and caregivers’ oral health knowledge, attitude, and practice (KAP) were extracted from the 4th National Oral Health Survey of China. The associations between ECC prevalence and various KAP variables were tested with chi-square tests, bivariate analysis and multivariable logistic regression analyses.Results: The ECC prevalence in Shandong Province was 64.6%, and the dmft mean was 3.15. The independent variables with an increased risk for ECC were age, feeding method within 6 months of birth, bedtime sugar frequency, experience of toothache over the past year and dental visits (P<0.05, chi-square tests). Complete breastfeeding within 6 months of birth primarily contributed to the high ECC risk of the 3-year-old group (OR: 3.39, 95% CI: 1.41-8.17), while high frequency bedtime sweet consumption mainly contributed to that of the 5-year-old group (OR: 3.22, 95% CI: 1.03-10.06; logistic regression analysis). Tooth brushing was not associated with ECC in this study, and some positive knowledge and attitude variables were positively correlated with a high risk of ECC.Conclusion: These data provide evidence to suggest that the ECC-related risk factors at different ages are inconsistent, which provides some insights for OHE. We should highlight the effects of feeding methods in the early stages of deciduous dentition and sugar habits in the late stages of deciduous dentition on ECC, as well as encourage preventive dental visit and supplemental training for oral health practices.
