Abstract The study of dental development in individuals born with cleft lip and palate (CLP) serves to determine when orthodontic intervention should start. Objective To evaluate the permanent second molar development in children born with cleft lip and palate according to Demirjian’s and Nolla’s methods. Methodology Out of a total of 513 digital panoramic radiographs, 113 pairs of children aged 3 to 16 years were selected. The exams were from children born with or without cleft lip and palate, of the same sex, with an age difference of up to 30 days. The images were analyzed by three examiners and reliability was checked through intra-examiner agreement by the Kappa test. The data were analyzed by Wilcoxon's and Mann-Whitney tests according to each dataset. Results The findings indicated delayed development of the permanent second molars in children with CLP (P<0.001). The development of the right permanent second molar was delayed compared to the left molar in children with CLP. Moreover, mandibular teeth showed significantly earlier development than maxillary teeth in both the case and control groups. There was no significant difference in the development of permanent second molars between sexes. Conclusion Children with CLP presented delay in the development of permanent second molars.

RESUMO Objetivo: Determinar o perfil das crianças de 6 a 12 anos de idade, com relação à ansiedade frente ao tratamento odontológico e avaliar os principais fatores desencadeadores de ansiedade nesta população. Métodos: A amostra foi composta por 200 crianças com idade média de 8,5 anos que frequentaram a Clínica-Escola de Odontologia da Universidade Federal de Campina Grande e as Unidades Básicas de Saúde da Família do município de Patos-PB entre junho de 2015 e maio de 2016. A ansiedade foi avaliada utilizando a Dental Anxiety Scale e o Venham Picture Test. O teste Qui-Quadrado e Exato de Fisher foram usados para explorar o nível de significância das associações entre as variáveis. Resultados: A ansiedade foi observada na maioria das crianças (Dental Anxiety Scale - 89% e Venham Picture Test - 70,5%) e os níveis predominantes foram baixo e moderado. A faixa etária da criança foi associada significativamente à ansiedade (p=0,014) através do teste Venham Picture Test, ao passo que o gênero não apresentou essa correlação. A ansiedade sofreu influência de todos os fatores estudados: marcação da consulta, sala de espera, caneta odontológica e raspagem periodontal. Conclusão: A maioria das crianças apresentou ansiedade e os fatores desencadeadores marcação da consulta, sala de espera, caneta odontológica e raspagem periodontal atuaram consideravelmente para o seu desenvolvimento.

ABSTRACT Objective: To determine the profile of children from 6 to 12 years of age, in relation to anxiety towards dental treatment and evaluate the main factors that trigger anxiety in this population. Methods: The sample was composed of 200 children with an average age of 8.5 years who attended the Clinic of the School of Dentistry of the Federal University of Campina Grande and the Basic Healthcare Units of the municipality of Patos, Paraíba, Brazil between June 2015 and May 2016. Anxiety was assessed using the Dental Anxiety Scale and the Venham Picture Test. The Chi-Square test and Fisher’s exact test were used to explore the level of significance of the associations between the variables Results: Anxiety was observed in the majority of children (Dental Anxiety Scale - 89% and Venham Picture Test - 70.5%) and the predominant levels were low to moderate. The child´s age group was significantly associated with anxiety (p=0.014) by the Venham Picture Test, while gender did not present this correlation. Anxiety was influenced by all the factors studied: making the appointment, waiting room, rotary instrument and periodontal scaling. Conclusion: The majority of children presented anxiety and the trigger factors: making the appointment, waiting room, rotary instrument and periodontal scaling contributed considerably to its development.

RESUMO Objetivo: estudar os dados epidemiológicos de pacientes vítimas de traumas bucomaxilofaciais atendidos em um hospital de referência da Paraíba. Métodos: estudo transversal de abordagem indutiva com procedimento estatístico comparativo e técnica de pesquisa por documentação direta em campo. O universo foi constituído dos prontuários hospitalares obtidos de janeiro de 2016 a dezembro de 2017 de pacientes atendidos pelo Serviço de Cirurgia e Traumatologia Bucomaxilofacial desse hospital. A amostra foi composta por 332 pacientes de acordo com os critérios de elegibilidade do estudo. A coleta de dados foi realizada por dois examinadores previamente calibrados e os dados foram analisados descritiva e inferencialmente. Resultados: os pacientes do sexo masculino foram mais acometidos por trauma facial (83,1%), principalmente na terceira década de vida (32,2%). Acidentes motociclísticos foram a etiologia mais comum de trauma para ambos os sexos. Em relação à estatística inferencial com margem de erro fixada em 5%, não foi observada associação significativa (p>0,05) entre os sexos e os fatores etiológicos do trauma. Os ossos do nariz (38,2%) foram os ossos mais afetados e a lesão mais frequente de partes moles foi o edema, em 50,9% dos casos. Apenas 20,8% dos pacientes com fraturas ósseas foram politraumatizados. Conclusão: as vítimas de traumatismo bucomaxilofacial atendidas em nosso hospital são predominantemente homens na terceira década de vida, envolvidos em acidentes motociclísticos e com lesões em ossos do nariz.

ABSTRACT Objective: to study the epidemiological data of patients suffering from buccomaxillofacial trauma treated at a referral hospital in the State of Paraíba. Methods: we conducted a cross-sectional study of inductive approach, with a comparative statistical procedure and research technique by field direct documentation. The sample comprised hospital records obtained from January 2016 to December 2017 of patients attended by the Service of Buccomaxillofacial Surgery and Traumatology of this hospital, and consisted of 332 patients according to the study’s eligibility criteria. Two previously calibrated examiners collected and analyzed the data, both descriptively and inferentially. Results: males sustained the majority of facial trauma (83.1%), mainly in the third decade of life (32.2%). Motorcycle accidents were the most common etiology of trauma for both genders. In relation to inferential statistics with a margin of error of 5%, there was no significant association (p>0.05) between the genders and the trauma etiological factors. The bones of the nose (38.2%) were the most affected bones and the most frequent soft tissue injury was edema, in 50.9% of cases. Only 20.8% of the patients with bone fractures were polytraumatized. Conclusion: the victims of oral and maxillofacial trauma attended at our hospital are predominantly men in the third decade of life, involved in motorcycle accidents and sustaining lesions in the nose bones nose.
