“…The results of the present study were consistent with those of a previous study that used conventional radiographic imaging to investigate the anatomic relationship of the MC with surrounding structures in mature mandibles (15). Moreover, the present findings are also in agreement with another study showing similar distances and overall shorter distances in women compared with men (16). Clinically, this indicates that the potential risk of iatrogenic nerve damage may be more common in females (3,17).…”

“…To the best of our knowledge, there is no other study including such a large number of patients (N = 627) with a comparable number of teeth (N = 1974) and roots (N = 3127). Previous cadaveric studies and even CBCT studies are based on a smaller number of patients and teeth (9,10,(14)(15)(16).…”

Context:Better understanding of the anatomical location and course of the mandibular canal is necessary to avoid damaging inferior alveolar nerve.Aims:The aim of this study was to investigate the buccolingual course of the inferior alveolar canal (IAC) in different mental foramen locations, using cone beam computed tomography.Materials and Methods:Three hundred and twelve hemimandibular images were evaluated in this study. The location of mental foramen in relation to the apices of mandibular premolar and molar teeth were recorded. Nine measurements (in millimeters) were taken at the level of the IAC and posterior mandibular premolar and molar root apices. Relative distances of IAC to buccal and lingual mandibular cortex were calculated for different mental foramen types.Statistical Analysis Used:Data were analyzed by one-way analysis of variance and P < 0.05 was considered to be statistically significant.Results:The distribution of subjects according to the type of mental foramen includes: Type 1 = 50.3% (at the level of second premolar apex), Type 2 = 33% (between the apices of first and second premolars), and Type 3 = 16.7% (between the apices of second premolars and first molars). The buccolingual ratio of the IAC position was statistically significant in different mental foramen types (P = 0.00).Conclusion:The position of IAC was affected by the location of the mental foramen. The direction of IAC gradually changed from lingual to buccal and from posterior to anterior.

“…Cone-Beam computerized tomography, in addition to its low cost and lower dose of radiation in relation to the spiral (Fan-Beam) computerized tomography, gives better visualization of the anatomical references. This contributes to the reduction of damage to the nerves and blood vessels, and the improved efficiency of anesthetic blocks [9][10][11][12] .…”

ResumoIntrodução: O conhecimento das estruturas anatômicas localizadas na região entre os forames mentuais é de importância crucial nos planejamento pré-operatórios. Objetivo: Avaliar a posição do forame mentual relacionado aos ápices dos dentes, sua distância aos bordos da mandíbula com uso da tomografia computadorizada de feixe cônico. Material e método: Foram avaliadas 100 tomografias computadorizadas de feixe cônico da mandíbula realizada num único aparelho de tomografia. Cada imagem escolhida foi avaliada de forma repetida para ambos os lados da mandíbula, a posição do forame mentual, indicando a região em que o forame se encontrava e as medidas do forame mentual a cortical lingual e base da mandíbula. Os dados foram analisados inicialmente de forma descritiva. Um valor de p<0,05 foi escolhido como o nível de significância. Resultado: 42% dos forames mentuais estavam localizados no ápice do segundo pré-molar. A margem lingual do forame mentual localizou-se em média de 3,1 mm a partir da cortical lingual. A margem inferior do forame mentual foi localizada 7,25 mm acima da borda inferior da mandíbula. Conclusão: O forame mentual localizou-se com maior frequência em nível dos ápices dos segundos pré-molares, com distância à cortical lingual, em média, de 3,1 mm e base da mandíbula, em média, de 7,25 mm.Descritores: Nervo mandibular; mandíbula; tomografia computadorizada de feixe cônico. AbstractIntroduction: Knowledge of the anatomical structures located in the region between the mental foramina is of critical importance in pre-operative planning. Objective: To evaluate the position of the mental foramen relative to the apices of the teeth and the distance to the edges of the mandible, using cone beam computerized tomography. Material and method: One hundred cone beam computerized tomographs of the mandible were evaluated; the tomographs were taken using a single tomographic device. Each image chosen was evaluated repeatedly from both sides of the mandible, the position of the mental foramen, indicating the region in which the foramen was found and the measures of the mental foramen, the lingual cortex and the mandibular base. Initially, the data were analyzed descriptively. A value of p<0.05 was chosen as the level of significance. Result: Forty-two percent of the mental foramina were located in the apex of the second pre-molar. The lingual margin of the mental foramen was located, on average, 3.1mm from the lingual cortex. The lower margin of the mental foramen was located 7.25 mm above the lower edge of the mandible. Conclusion: The mental foramen was located more frequently at a level of the apices of the second pre-molars, with a distance to the lingual cortex, on average, of 3.1mm and to the base of the mandible, on average, of 7.25 mm.
