PURPOSE The purpose of this study was to evaluate the presence of signs and symptoms of temporomandibular disorders (TMD) in children with headaches in a neuropediatric ambulatory. METHOD Fifty patients between 4 and 18 years of age were examined: 31 had headaches (24 migraine, 4 tension type and 3 unspecific headache) and 19 formed the control group. The data collection was comprised of a structured questionnaire answered by the childrens parents, and a subjective evaluation about the childrens emotional state. A specific questionnaire for TMD was applied, followed by a clinical dental examination of the children. As signs of TMD, mouth opening limitation, mandibular trajectory deviation in opening mouth, and joint noise were considered. As symptoms, pain on palpation of masseter and temporal muscles and on the poromandibular joint. RESULTS A significant increase in signs and symptoms of TMD was found in patients with headaches when compared to the control group. There was also a significant difference in signs and symptoms of TMD according to age (increased with age) and emotional state (tense>calm). CONCLUSION There is a higher frequency of TMD in pediatric patients with headaches; thus, it is important to look for TMD signs and symptoms in this population.

Case Report. An 8-year-old girl with amelogenesis imperfecta (AI) reported unsatisfactory aesthetics, difficulty in mastication, and dental hypersensitivity. The intraoral examination observed mixed dentition, malocclusion in anteroposterior relationships, anterior open bite, and dental asymmetry. A hypoplastic form of AI was diagnosed in the permanent dentition. A multidisciplinary planning was performed and divided into preventive, orthopedic, and rehabilitation stages. Initially, preventive treatment was implemented, with fluoride varnish applications, in order to protect the fragile enamel and reduce the dental sensitivity. In the second stage, the patient received an interceptive orthopedic treatment to improve cross-relationship of the arches during six months. Finally, the rehabilitation treatment was executed to establish the vertical dimension. In the posterior teeth, indirect composite resin crowns were performed with minimally invasive dental preparation. Direct composite resin restorations were used to improve the appearance of anterior teeth. Follow-Up. The follow-up was carried out after 3, 6, 12, and 18 months. After 18 months of follow-up, The restoration of integrity, oral hygiene, and patient satisfaction were observed . Conclusion. Successful reduction of the dental hypersensitivity and improvement of the aesthetic and functional aspects as well as quality of life were observed.

Violence against children and adolescents is a public health issue worldwide that threatens physical and mental wellbeing and causes irreparable harm. Reports on this violence are an essential way to prevent it and to protect the children and adolescents. Thus, the objective of the present study was to evaluate the prevalence of physical injuries that occur in domestic environments and reported to the Child and Adolescent Protection Network. This retrospective study was conducted at the Epidemiology Center of the Municipality of Curitiba. A total of 10,483 reports for the years 2010 (5,112) and 2011 (5,371) were analyzed and from them were selected reports of physical injuries that occurred in the family environment. The children and adolescents were 0-17 years old, comprising 322 cases of physical abuse within the family in 2010. Out of these, 57.1% were male and 42.9% were female, and 58% (187) presented head and neck injuries. There were 342 reports in 2011, 49% were male and 51% were female; head and neck injuries corresponded to 65% (222) of the reported cases. The prevalence of injuries increased by 6% and head and neck injury increased by 19% between 2010 and 2011. It may be concluded that physical abuse is associated with a high prevalence of head and neck injury, which is easily observed by the health and education professionals. Notification organs should be created in Brazilian hospitals and health centers, which is essential to conduct epidemiological surveillance and appropriate policies.

Background The prevalence of signs and symptoms of temporomandibular disorders (TMD) increases during adolescence and adulthood. Few studies have examined TMD prevalence in Brazilian adolescents. Aim To investigate the prevalence of TMD in Brazilian adolescents. Methods A representative population-based sample of 934 adolescents (10–14-years-old) was examined. TMD screening was performed using a questionnaire by the American Academy of Orofacial Pain. TMD diagnoses used research diagnostic criteria for temporomandibular disorders (RDC/TMD—Axis-I). Examinations were performed by a single calibrated examiner (kappa > 0.80). Results The prevalence of TMD symptoms was 34.9%; the most frequently reported symptoms were headache and neck ache (20.9%), followed by joint sounds (18.5%). Myofascial pain was the most prevalent type (10.3%), followed by disc displacement with reduction (8.0%) and arthralgia (3.5%). There was a significant association between sex and TMD symptoms; prevalence was significantly higher in girls (RP = 1.37; 95% CI = 1.14–1.65; p = 0.001). Myofascial pain of TMD and displacement with reduction were more prevalent in girls (RP = 1.76; p = 0.007 and RP = 2.06; p = 0.004, respectively). Conclusion TMD symptoms were present in 34.9% of adolescents, with myofascial pain being the most prevalent type (10.3%). TMD was significantly more common in girls. Routine pediatric dental care should include a TMD screening.

The aim of this study was to evaluate the shear bond strength of rebonded ceramic brackets after subjecting the bracket base to different treatments. Seventy-five premolars were selected and randomly distributed into five groups (n=15), according to the type of the bracket surface treatment: I, no treatment, first bonding (control); II, sandblasting with aluminum oxide; III, sandblasting + silane; IV, silica coating + silane; and V, silicatization performed in a laboratory (Rocatec system). The brackets were fixed on an enamel surface with Transbond XT resin without acid etching. The brackets were then removed and their bases were subjected to different treatments. Thereafter, the brackets were fixed again to the enamel surface and the specimens were subjected to shear bond strength (SBS) test. The adhesive remnant index (ARI) was then evaluated for each specimen. Data were subjected to ANOVA and Tukeys tests (α=0.05). A statistically significant difference was observed only between Rocatec and the other groups; the Rocatec group showed the lowest SBS values. The highest SBS values were observed for group 1, without any significant difference from the values for groups II, III and IV. Most groups had a higher percentage of failures at the enamel-resin interface (score 1). It was concluded that the surface treatments of rebonded ceramic brackets were effective, with SBS values similar to that of the control group, except Rocatec group.

The objective of this study was to present a classification of the root development stage of female rat molar teeth and to evaluate the variation in the lactate dehydrogenase (LDH) activity and electrophoretic isoenzyme profile according to the stage of root development of the molar teeth. We also studied the LDH activity and isoenzymes of the pulp of incisor teeth. The stage of development of the rat first molar at the age of 15 days and that of the second molar at the age of 18 days was classified as the beginning of root formation. At the age of 15 days, the electrophoretic profile of the isoenzymes for the first molar showed a prevalence of LDH-1 followed by LDH-2. However, for the maxillary second molar there was a prevalence of LDH-4 followed by LDH-1, while for the mandibular second molar LDH-1 predominated followed by LDH-2 and LDH-4. From 18 days of age, the prevalence was always of LDH-1. The electrophoretic profile of LDH isoenzymes from the pulp of the incisor teeth at the ages studied (25 and 60 days) showed the following order of prevalence: LDH-1 > LDH-2 > LDH-3 > LDH-4 > LDH-5. These results suggest that there are variations in the prevalence of the various forms of LDH isoenzymes in the dental pulp of rats according to the developmental stage of the root.

BACKGROUND Few studies have evaluated the oral health status of children with a history of maltreatment. AIM This case-control study evaluated oral health in children who were victims of abuse and in child protective services in Curitiba, Brazil. DESIGN One hundred twenty-two children who were victims of abuse and 240 children with no history of abuse (mean ages, 8.56 and 8.24 years, respectively) were included in the study. Dental caries were assessed according to the Decayed, Missing, or Filled Teeth index (dmft index and DMFT index) by two calibrated examiners. The presence of anterior open bite and posterior crossbite was recorded. Data were analyzed using bivariate and adjusted odds ratios using a multivariate logistic regression model analyses. RESULTS In the case group, we found a higher DMFT index (P < 0.001) and a significantly higher prevalence of missing primary teeth (P = 0.04), untreated decayed permanent teeth (P < 0.001), filled permanent teeth (P < 0.001), and anterior open bite (P = 0.04). Children who were victims of abuse presented an odds ratio of 6.48 (95% CI: 3.52-11.95) for caries in permanent teeth and an odds ratio of 2.28 (95% CI: 1.04-4.99) for open bite. CONCLUSION Victims of child abuse had a worse oral health status, demonstrating the need to establish special policies for oral healthcare for this population.

PurposeThe purpose of this study is to evaluate general anxiety using the State-Trait Anxiety Inventory (STAI) and dental anxiety using the Corah Dental Anxiety Scale (Corah-DAS) in patients who underwent surgical procedures for dental implants.MethodsThe study was performed with 55 patients who underwent implant surgery, of whom 37 were treated at a university and 18 were treated at a private office. General anxiety (STAI) and dental anxiety (Corah-DAS) were assessed at three different time points: appointment prior to clinical procedures (T1), day of procedures (just before the procedures; T2), and first post-procedure appointment (T3). The data were analyzed using analysis of variance followed by the Duncan test or Student’s t-test.ResultsState anxiety increased on the day of surgery (T2), whereas trait anxiety was higher at T1 (both p < 0.05). Women (n = 41) presented higher state anxiety at T2 than men (n = 14). Patients who were treated at the university (n = 37) exhibited higher state anxiety at both T1 and T3 than patients who were treated in a private practice (n = 18). Individuals with lower dental anxiety at T1 were those who reported having good experiences with dental treatment.ConclusionsAn increase in state anxiety was observed immediately before surgical procedures, and this increase was more pronounced in females. Although the Corah-DAS has been used as an indicator of dental anxiety, the STAI appears to be more sensitive for the measurement of anxiety. The application of appropriate methods is essential for ascertaining anxiety in patients, which should be considered in oral surgeries.

The aim of this study was to evaluate whether the theme child abuse is addressed in the undergraduate dentistry in Brazil. This is a cross-sectional exploratory study, in which all universities in the country with the course of dentistry were questioned. Questionnaires were forwarded to all 201 coordinators of education of dentistry in Brazil, which consist in all existing courses at the time of the research. 174 questionnaires were received by the coordinators; however, only 28 were answered (response rate of 16.09%). Of these, 19 (67.8%) were private institutions, 06 (21.4%) public and 03 (10.7%) were joint management. The theme is approached by 21 institutions (75%), mainly in the disciplines of Dentistry, Forensic Dentistry and Public Health. Regarding the amount of hours designated for this theme, 16 institutions (21.19%) mentioned to reserve 08 hours or less during the course, on the other hand, 14 institutions (66.66%) stated that they were required to approach this issue within the course. Due to the importance of the theme child abuse and compared to the results of this study, it seems reasonable to conclude that this matter has been worked very incipient in Dental Courses in Brazil.
