Objective: To evaluate the potentiating effect of different substances in antimicrobial action of calcium hydroxide.Methods: The agar diffusion method, was used with well technique, to analyze seven substances associated to calcium hydroxide to make some pastes, they are: chlorexidine, saline, anesthetic, malvatricin, propolis, hypochlorite, paramonochlorophenol.Results: The pastes with malvatricin and paramonochlorophenol presented greater inhibition zones against Enterococcus faecalis.Conclusion: There was potentialization in antimicrobial effect of calcium hydroxide when associated to paramonochlorophenol and to malvatricin especially against Enterococcus faecalis. Low increase of the antimicrobial capacity was observed when using chlorexidine as vehicle to calcium hydroxine paste.
This study aimed to estimate the prevalence of external and internal numerical root variations of mandibular canines and premolars in southern Bahia. 384 Panoramic Radiography (PAN) and 384 Cone Beam Computed Tomography (CBCT) of patients over 14 years old who had all mandibular canines and premolars were evaluated for internal and external numerical variation. Gender predilection of morphological configurations was assessed using the x 2 test (p <0.05). For the PAN, 0.5% of the patients had a canine with two roots, while 2.1% and 3% had first premolar and second premolar with two roots, respectively. Regarding internal variation, 2.9% had a canine with two canals, while 15.9% and 6.5% had a first premolar and second premolar with two canals, respectively. For the CBCT, 2.7% of the patients had a canine with two roots, while 16.4% and 2.1% had first premolar and second premolar with two roots, respectively. Three rooted first and second premolar accounted for 0.3%. Regarding the internal variation, 3.4% had a canine with two canals, while 24% and 6.5% had a first premolar and second premolar with two canals, respectively. Three or four canals accounted for 0,7% for first premolars and 0.3% for second premolars. Despite many variants, the most prevalent root configuration for these groups in Bahia´s southern region is one root with one canal. This finding may serve as a guide in clinical endodontic therapy.
Resumo. Dentre as áreas de competência de atuação do perito odontolegal está a identificação humana. A estimativa de idade é uma das pesquisas mais utilizadas para identificação dos indivíduos, podendo ser realizada tanto em vivos, quanto em mortos. Os dentes são considerados excelentes meios a fim de se estimar idade, uma vez que possuem maior resistência a alterações químicas, físicas, além de apresentar características morfológicas exclusivas em cada indivíduo. O objetivo desse trabalho é verificar, por meio de um estudo piloto, a aplicabilidade da metodologia de estimativa da idade proposta por Nicodemo, Moraes e Médici (1974) com base na mineralização dos dentes em população do Sul da Bahia. Foram analisadas 40 radiografias panorâmicas de acordo com o método proposto, 20 do sexo masculino e 20 do sexo feminino, de idades variando entre 72 e 119 meses, sendo posteriormente realizada uma análise comparativa referente aos parâmetros de sexo e faixa etária, assim como a análise comparativa da diferença relativa entre as estimativas produzidas em diferentes etapas do estudo. As amostras obtiveram um alto índice de correlação, com acerto em 80% da amostra masculina e 70% da amostra feminina, sendo um método considerado efetivo na população estudada, não havendo diferenças significativas entre as análises realizadas em períodos distintos pelo examinador. Observa-se, portanto, ser uma metodologia acessível uma vez que pode ser aplicada por cirurgiões-dentistas sem experiência prévia do método e de baixo custo, sendo necessário o 22 Brazilian Journal of Forensic Sciences, Medical Law and Bioethics 8(1):21-35 (2018) V. A. O. Furtunato et al. aumento da amostra e a inclusão de outras características populacionais, bem como uma maior amplificação etária para verificação dos limites de relevância do estudo. Palavras-chave: Odontologia; Radiografia panorâmica; Odontologia legal; Antropologia forense.Abstract. Within the field of competence of foresinc dentistry expertise is the human identification. The age estimate is one of the most used researches for individual identification, being able to be used in the living and in the dead. Te ethare considered excellent to be studied in order to estimate the age, since they have greater resistance to chemical and pshysical changes, besides showing the pecualirity of each individual when presenting unique morphological characteristics. The objective of this study is to verify the applicability of the methodology of age estimation proposed by Nicodemo, Moraes and Médici (1974) based on tooth mineralization in the population of southern Bahia. A total of 40 panoramic radiograph exams were analyzed according to the proposed method, of which 20were male and 20 female, ranging in age from 72 to 119 months, and a comparative analysis was performed regarding the parameters of gender and age group and to the comparative analysis of the relative difference between the estimates produced in different stages of the study. The samples obtained a high correlation index, with 80% of the male s...
