Due to constant changes in the process of working in the dental market, knowing the profile of the egress of a high education institution contributes to trace the profession changes, trends and needs, besides contributing on course decisions. The profile of the dental surgeon graduated from the State University of Piaui (UESPI), Campus Professor Alexandre Alves de Oliveira Parnaíba-PI, was studied to evaluate the professional trajectory of graduates from term 2 year 2004 to term 2 year 2014, through a survey with information on personal data, socioeconomic and demographic profile, field of action and academic training. It was observed that most of the graduates are female, in the age group between 20 and 30 years and works in the public sector. As for graduate courses, Orthodontics was the most cited specialization. Most of them act in Piauí, with the largest number of professionals acting in the interior of the state. They make 20 to 60 consultations per week on average and most do not work with covenants or accreditations. In addition, the average salary is up to 10 minimum Brazilian wages and the majority report being satisfied financially and with their academic background. However, they pointed out the discipline "Management, Administration and Marketing in Dentistry" necessary to improve the curricular matrix of the course. Descriptors: Dentistry. College Education.

This paper describes two cases of instrument fragment removal from the apical thirds of root canals using a customized extractor and a modified needle technique, respectively. In case 1, a customized extractor was manufactured to remove a bur fragment located in the apical root canal of a maxillary central incisor. The use of this extractor enabled successful and conservative removal of the instrument fragment. In case 2, a modified injection needle was used as a trepan to gain access around an instrument fragment located in the curved apical portion of the mesiobuccal canal of a mandibular molar. A segment of steel wire was inserted into the needle lumen to engage the metallic fragment, enabling its removal with counter-clockwise rotation and a simultaneous pull-out motion. Alternative and creative methods are useful for the management of intracanal metallic fragments during root canal treatment.

Introdução: As alterações que ocorrem no processo de odontogênese são denominadas anomalias dentárias e são classificadas quanto à forma, como geminação, fusão, concrescência, dilaceração, cúspide em garra, dens in dente, taurodontia, micro e macrodontia, quanto ao número: dentes ou raízes supranumerários e agenesias e quanto posição, como transmigrações ou ectopias. Objetivo: Determinar a prevalência das anomalias dentárias radiografias de prontuários de pacientes atendidos na clínica de uma Instituição de Ensino Particular. Material e Métodos: Análise de 300 radiografias panorâmicas em negatoscópio, iluminado por duas lâmpadas fluorescentes de 20 watts cada, recoberto com máscara preta, com uma abertura central medindo 15x30 cm onde o filme panorâmico foi fixado, realizadas em ambiente escuro e, com o auxílio de lupa (aumento 2X) e interpretadas conjuntamente por dois observadores calibrados. Os achados radiográficos foram registrados em tabela própria, constando número prontuário, gênero, presença de alterações e anomalias dentárias de forma, número e posição. A análise estatística descritiva foi realizada pelo cálculo da frequência e percentual de acometimento e relações entre gênero e alterações dentárias encontradas. Resultados: Ocorrência de dilacerações (3,32%), dentes cônicos (1%), taurodontia (0,66%), dens in dente (0,33%) e cúspide em garra (5,66%), em relação às anomalias de tamanho observaram-se microdontias (5,33%), nos distúrbios de posição ocorrência como erupção ectópica (0,33%) e em casos de alterações de número, dentes (4,32%) e raízes supranumerárias (0,66%), sem diferenças estatísticas entre os gêneros. Conclusão: A prevalência de variações anatômicas em dentes permanentes é baixa, porém não rara, sem distinção entre os gêneros, mas de significado clínico por induzir, em algumas situações, o comprometimento pulpar ou dificultar terapias odontológicas.

Introduction: Medication-related osteonecrosis of the jaw (MRONJ) occurs by the use of a drug that has osteonecrosis as one of its side effects. Case Report: We describe a case of a 48-year-old oncological patient who had brain and bone metastasis due to breast cancer and was medicated with bisphosphonates (BPs). She presented cavities, and after an incorrect exodontia, the lesion evolved into a jaw osteonecrosis. Then she did a sequestrectomy and was treated using laser therapy. Radiological and clinical features are also described. Conclusion:In a case like this, we notice how necessary is a complete evaluation of the oncological patient before some procedures and laser therapy as an effective ally in the management.

Objectives This study aimed to evaluate the effects on bone repair of different concentrations of mineral trioxide aggregate (MTA) added to AH Plus. Materials and Methods Bone tissue reactions were evaluated in 30 rats ( Rattus norvegicus ) after 7 and 30 days. In the AH + MTA10, AH + MTA20, and AH + MTA30 groups, defects in the tibiae were filled with AH Plus with MTA in proportions of 10%, 20% and 30%, respectively; in the MTA-FILL group, MTA Fillapex was used; and in the control group, no sealer was used. The samples were histologically analyzed to assess bone union and maturation. The Kruskal-Wallis and Mann-Whitney tests were performed for multiple pairwise comparisons ( p ≤ 0.05). Results At the 7-day time point, AH + MTA10 was superior to MTA-FILL with respect to bone union, and AH + MTA20 was superior to MTA-FILL with respect to bone maturity ( p < 0.05). At the 30-day time point, both the AH + MTA10 and AH + MTA20 experimental sealers were superior not only to MTA-FILL, but also to AH + MTA30 with respect to both parameters ( p < 0.05). The results of the AH + MTA10 and AH + MTA20 groups were superior to those of the control group for both parameters and experimental time points ( p < 0.05). Conclusions The results suggest the potential benefit of using a combination of these materials in situations requiring bone repair.
