These results indicate an important role for the serotonergic system in the anxiolytic-like effect of lavender essential oil.

BackgroundThe prevalence of signs and symptoms of temporomandibular disorders (TMD) increases during adolescence and adulthood. Few studies have examined TMD prevalence in Brazilian adolescents.AimTo investigate the prevalence of TMD in Brazilian adolescents.MethodsA 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).ResultsThe 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).ConclusionTMD 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.

Objective: To provide information with the purpose of helping pediatricians to recognize the risk factors for the onset of severe early childhood caries, allowing for early intervention and thus avoiding this preventable disease and its consequences. Sources:Information was collected from scientific articles published on the databases SciELO, MEDLINE and PUBMED in last 25 years, as well as technical books and guidelines of international committees. The keywords used were: early childhood caries, severe early childhood caries, dental caries, and children. Summary of the findings:Severe early childhood caries affects infants and children. It is infectious, has a multifactor etiology and fast development, starting soon after dental eruption. Due to the presence of local sociocultural risk factors, it must be regarded as a symptom of alteration in the child's health and lack of adequate care. Its manifestations include pain, abscesses and chewing difficulty, affecting the child's feeding and sleep. Furthermore, it also affects the child's general health, speech, and self-esteem. Conclusions:Preventive methods to avoid severe early childhood caries have been developed and they should be used as early as possible by means of prevention programs carried out in the community and with families. Professionals responsible for providing care to babies and children should be aware of cases at risk for caries and interfere in order to improve their patients' health.J Pediatr (Rio J). 2009;85(4):295-300: Dental caries, children, severe early dental caries. ResumoObjetivo: Fornecer informações para auxiliar o médico pediatra a reconhecer os fatores de risco para o início da cárie precoce na infância e da cárie severa na infância (CSI), possibilitando a intervenção precoce de tais fatores, e, assim, evitar a instalação dessa doença prevenível e as suas consequências. Fontes dos dados:As informações foram coletadas a partir de artigos científicos publicados nas bases de dados SciELO, MEDLINE e PUBMED nos últimos 25 anos, livros técnicos e publicações de consenso de organismos internacionais. As palavras-chave utilizadas foram: early childhood caries, severe early childhood caries, dental caries e children. Síntese dos dados:A CSI é uma forma de cárie dentária que afeta bebês e crianças. É infecciosa, de etiologia multifatorial e de desenvolvimento rápido, iniciando logo após a erupção dos dentes. Por apresentar fatores de risco local e sociocultural, deve ser considerada como sintoma de uma alteração na criança e de falta de cuidados adequados. Suas manifestações incluem dor, abscessos e dificuldades mastigatórias, afetando a alimentação e o sono da criança. Além disso, afeta também sua saúde geral, fala e autoestima. Conclusões:A CSI é uma doença com métodos preventivos estabelecidos, que devem ser introduzidos o mais precocemente possível, por meio de programas preventivos na comunidade e no núcleo familiar. Os profissionais que atendem bebês e crianças devem estar atentos aos casos com risco para o desenvolvimento da d...
