Analise radiografica e histologica da evolução de lesões periapicais em cães normais e imunossuprimidos
[s.n.], 2018Co-Authors: Eneida Barros Santos De AraujoAbstract:Orientador: Francisco Jose de Souza FilhoDissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Odontologia de PiracicabaResumo: A influência da imunossupressão no desenvolvimento de lesões periapicais é pouco conhecida. Neste estudo, os canais radiculares de cães normais e imunossuprimidos foram expostos ao meio bucal para contaminação, após pulpectomia com e sem ampliação do forame apical, para promover o desenvolvimento de lesões periapicais. Foi observado através da análise radiográfica e histológica, que o esenvolvimento de lesões periapicais não apresentou alterações entre cães normais e imunossuprimidos, havendo um aumento linear no tamanho e aumento na intensidade do processo I inflamatório, de acordo com os períodos de 30, 60 e 90 dias. A ampliação do. forame apical exerceu influência na intensidade da reação inflamatória periapical, nos diversos períodos estudadosAbstract: The influence of the immunosuppresion on the development of periapical lesions is not well elucidated.

a morphometric study of Foramen ovale and Foramen spinosum of the human sphenoid bone in the southern nigerian population
Journal of Applied Biosciences, 2010Co-Authors: E A Osunwoke, C C Mbadugha, C N Orish, E L Oghenemavwe, C J UkahAbstract:Objective : Conduct a morphometric study of foramina ovale and spinosum of the human sphenoid bone. Methodology and results : The study was carried out using 87 dry adult human skulls obtained from cadavers in the laboratories of the Departments of Anatomy of the Universities of Port Harcourt, Nnamdi Azikiwe University, Nnewi Campus, Okofia, University of Nigeria, Enugu Campus, Niger Delta University, Amassoma, Abia State University, Uturu and University of Calabar, all in Southern Nigeria. Measurements were done using a pair of dividers to span across the anteroposterior (length) and transverse (width) margins of the foramina and then transferred to a meter rule for the readings to be taken. The lengths of right and left Foramen ovale were 5.0 – 9.5mm and 5.0 – 9.0mm, respectively. The mean of the lengths of the right Foramen ovale was 7.01±0.10mm while that of the lengths of the left Foramen ovale was 6.89± 0.09mm. The widths of both right and left Foramen ovale were 2.0 - 5.0mm. The mean of the widths of the right Foramen ovale was 3.37± 0.07mm while that of the left Foramen ovale was 3.33±0.07mm. There was no significant difference between the mean of the length and width of the right and left Foramen ovale. The length of right and left Foramen spinosum was 1.5 - 3.5mm and 1.0 - 4.0mm, respectively. The mean of the length of the right Foramen spinosum was 2.34 ±0.05mm while that of the left was 2.36±0.05mm.The width of both right and left Foramen spinosum was 1.0mm to 2.0mm. The mean of the widths of the right Foramen spinosum was 1.66±0.03mm while that of the left Foramen spinosum was 1.61±0.03mm. There was no significant difference between the mean of the length and width of the right and left Foramen spinosum. Conclusion and application : This study is of clinical and anatomical significance to medical practitioners in cases of trigeminal neuralgia and in diagnostic detection of tumors and abnormal bony outgrowths.

position and number of mental Foramen in dry human mandibles comparison with respect to sides and sexes
OA Anatomy, 2013Co-Authors: R Pokhrel, R BhatnagarAbstract:Abstract Introduction Mental Foramen of mandible has been found to vary in its position, number and distance from the surrounding bony landmarks. This variation occurs with populations as well as with factors like ethnicity, age, sex and sides. Knowledge of this variation is important for localisation of the mental nerve during surgeries in this region. This study was undertaken to document the variations in number and location of mental Foramen with sexes and sides in dry mandibles of Indian origin. Materials and methods The sample consisted of 83 dried mandibles of known sex, 53 males and 30 females. The position of mental Foramens was measured in relation to mandibular teeth and its distance from three bony landmarks—mental symphysis, alveolar border and lower border of mandible. Incidence of accessory mental Foramen was noted. Results The most common position of mental Foramen was at the apex of the second premolar (48.8%) and the next was between the apices of the first and second premolars (30.1%), this pattern being the same for both sides of both sexes with no statistical significance. Accessory mental Foramen was found in 7.22% sides, bilaterally in 4.81% and was more common in males and in the right side. Mean lower border, alveolar border and mental symphysis were 12.60 ± 1.63, 12.39 ± 2.32 and 26.47 ± 2.54 mm respectively, with all values being significantly higher for males; differences between the sides were statistically insignificant. Conclusion The current study provides insight into the location and number of mental Foramen in Indians and explains the discrepancy seen among findings of earlier studies.
