Objective: To assess the oral health status of public school students of São Francisco do Conde, Bahia. Material and Methods: Cross-sectional, descriptive and analytical-comparative study with 350 children aged 7-12 years of both sexes. Oral health was analyzed using indicators recommended by WHO: soft tissue condition, DMFT, dmft, CPI, dental fluorosis, and DAI, and analysis of dental care, salivary examinations, chronology of eruption of permanent teeth, frequency of tooth brushing and visits to the dentist. The results were analyzed using descriptive statistics and statistical tests-t-Student, χ2, Fisher exact test, ANOVA, Tamhane and F Levene. Results: dmft and DMFT values of 1.45 and 0.53 were found, respectively. Among black (49.4%) and brown students (49.1%), 72.5 % had mixed dentition, 0.3% deciduous, and expected chronology of eruption of permanent teeth in 70.6 %, 56.3 % reported experiencing caries, 38.3% of children had fluorosis, 96.9% of individuals with normal saliva buffer capacity, while 23.2% had reduced salivary flow. CPI in children aged 12 years found that 79 % had healthy periodontium, no bleeding or presence of calculus. In relation to DAI, 21.1 % of children had normal or slightly altered occlusion and 71.5 % had some degree of malocclusion. Only 14.6 % of the sample reported not having had any contact with dentist and 38.6 % reported brushing their teeth three times a day or more. Conclusion: The oral health pattern of schoolchildren is satisfactory, requiring particular care with occlusion. The effectiveness of the results of this epidemiological survey allowed the adequacy of public policy actions on oral health in the municipality in which orthodontics service in the public network will be established.
Conflict of interest: non-existent stimulation of supporting structures, such as bones and teeth and for favoring that the harmonious craniofacial growth occurs³ .The chewing pattern can be influenced by several factors, such as occlusal interferences, dental and/ or periodontal problems, tooth loss, muscle and/or temporomandibular joints problems².It is known that in a unilateral mastication, the chewing muscles are mainly characterized by increased muscle strength on the working side, in other words, where chewing is occurring. The muscles of the balancing side, opposite side to the working side, is generally more elongated and with NTRODUCTIONChewing is considered by many authors as one of the most important and most studied functions of the stomatognathic system¹,². When performed in a alternating bilateral way, there is synchrony of masticatory muscles, which in turn are crucial for the ABSTRACT Purpose: to investigate the relationship of the masticatory preference side in the electrical activity of masseter and temporalis muscles. Methods: the sample was composed by 115 children aged between 7 and 12 years. The acquisition of the electrical activity of the masticatory muscles was recorded during 5 seconds of isometric contraction in maximal intercuspal position. The children were divided into four groups according to masticatory preference observed: Chewing Preferential Right, Left, Bilateral Alternating, and Bilateral Simultaneous. The electromyographicdata were analyzed using the SPSS 17.0 software, and for determination of statistical difference between the electrical activity of the right and left masseter and temporalis muscles was performed by Paired Student t-test (p <0.05). Results: from the total of 115 children, 76 (63.4%) had a preferred side during mastication, whereas 44 (36.7%) children had masticatory right and 32 (26.7%) preferred chewing left. Of the individuals without a preferred side, it was found 25.8% (n = 31) alternating with bilateral chewing and 10.8% (n = 13) with simultaneous bilateral chewing. After comparing the electrical activity of the masseter and temporal, right and left, according to the group chewing, it was found that the average electrical activity of the muscles on the left side showed no statistically significant differences when compared with the average of its peers right side. Conclusion: for the study sample, there was no relationship between the habitual chewing side and electrical activity of the muscles masseter and temporal.
A elevação da expectativa de vida de uma população resulta da interaçãode diversos fatores, como a descoberta dos antibióticos; dos imunobiológicosou vacinas, efetivação de políticas públicas para redução dapobreza e desigualdades como: ações de saneamento básico; habitaçãodigna e maior tempo de permanência na escola. Contudo, o processode envelhecimento acarreta maior incidência e prevalência de doençascrônicas não transmissíveis (DCNT), a exemplo das neurodegenerativas,especificamente a doença de Alzheimer (DA). A doença apresenta evoluçãogradual, com deterioração da memória, aprendizado, orientação,estabilidade emocional, capacidade de comunicação, pensamentos abstratos(paranoias e alucinações) tendo como consequência a incapacidadee exclusão social. Inicia-se com redução motora e cognitiva chegandoà perda da autonomia pessoal, inviabilizando a realização das atividadesda vida diária (AVDs) como nutrição e cuidados básicos de higiene oral.É condição essencial que os cirurgiões-dentistas conheçam característicasclinicas da DA para que os cuidados odontológicos sejam planejadosprevendo as etapas evolutivas da doença e a percepção dos pacientes eseus cuidadores. The increase in the life expectancy of a population results from the interactionof several factors, such as the discovery of antibiotics; immunobiológicosor vaccines, effective public policies to reduce poverty andinequalities such as: basic sanitation actions; housing and longer time inschool. However, the aging process leads to a higher incidence and prevalenceof chronic non-communicable diseases (NCDs), such as neurodegenerative diseases, specifically Alzheimer’s disease (AD). The diseasepresents gradual evolution, with deterioration of memory, learning, orientation,emotional stability, communication capacity, abstract thoughts(paranoias and hallucinations), resulting in incapacity and social exclusion.It begins with a motor and cognitive reduction, leading to the lossof personal autonomy, making it impossible to carry out activities of dailyliving (ADLs) such as nutrition and basic oral hygiene care. It is essentialthat dental surgeons know the clinical characteristics of AD so that dentalcare is planned by predicting the evolutionary stages of the disease andthe perception of patients and their caregivers.
