ABSTRACT

Introduction: One of the challenges of maxillofacial surgery is the rehabilitation of patients with severe bone loss, using implant-supported prostheses. This challenge is based on the small remaining bone structure, and on the need to reconstruct the structure for the rehabilitation with autogenous or exogenous grafts. Case report: We report the case of a patient with severe maxillary atrophy, where a skullcap graft was performed associated with implant placement and prosthetic completion 14 months after the start of treatment. Final considerations: We demonstrate clinical safety for the use of extraoral grafts without complications, representing a good alternative treatment for this group of patients.


Introdução: um dos desafios da cirurgia bucomaxilofacial é a reabilitação de pacientes com perda óssea severa, utilizando próteses implantossuportadas. Este desafio baseia-se na pequena estrutura óssea remanescente e na necessidade de reconstrução da estrutura para a reabilitação com enxertos autógenos ou exógenos. Relato de caso: Relatamos o caso de um paciente com atrofia maxilar grave, onde foi realizado enxerto de calota craniana associado à instalação de implante, com finalização protética 14 meses após o início do tratamento. Consideracoes finais: Demonstramos segurança clínica para o uso de enxertos extrabucais sem complicações, representando uma boa alternativa de tratamento para este grupo de pacientes.

ABSTRACT

Aim: This study aimed to systematically review existing literature regarding the association between dental procedures­such as tooth extractions and periodontal therapy­and occurrence of medication-related osteonecrosis of the jaw (MRONJ) in individuals using bone-modifying drugs. Methods: Search strategies were performed in PubMed, Scopus, Web of Science and Cochrane Library for a timeframe ending in December 2021. Study selection, data extraction and risk of bias were analyzed independently by two researchers. Three meta-analyses were performed, estimating the crude risk ratio (RR), the adjusted odds ratio (OR) and the adjusted hazard ratio (HR) for the association between tooth extraction and MRONJ. Results: Of the 1,654 studies initially retrieved, 17 were ultimately included. The majority of patients with MRONJ in these studies were female, with a mean age of 64 years. Zoledronic acid was the most commonly used drug among patients with MRONJ, and cancer was the most frequent underlying health condition. Regarding the performed meta-analyses, crude and adjusted analyses demonstrated that tooth extraction increased the risk for MRONJ by 4.28 (95% confidence interval [95%CI]: 1.73­10.58), the OR for MRONJ by 26.94 (95%CI: 4.17­174.17), and the HR for MRONJ by 9.96 (95%CI: 4.04­24.55). Conclusion: It was concluded that performing dental procedures, especially tooth extraction, in patients using bone-modifying drugs increased the risk of MRONJ occurrence and, therefore, should be avoided. Further studies, using adjusted data, are warranted

ABSTRACT

O nervo mandibular V3 é a terceira divisão do nervo trigêmeo, apresenta fibras motoras e sensitivas, sendo a ramificação mista deste nervo. Seus ramos eferentes são responsáveis pela motricidade dos músculos mastigatórios, inerva os músculos milo-hióideo, ventre anterior do digástrico, tensor do véu palatino e tensor do tímpano. Suas fibras aferentes são responsáveis pela sensibilidade da região inferior da face e cavidade oral, dentes inferiores, parte da língua e propriocepção da cápsula da articulação temporomandibular ATM. O objetivo deste estudo é explanar as possíveis lesões no nervo mandibular, suas ramificações e estruturas adjacentes no caso de fraturas na mandíbula, colaborando com informações detalhadas para posterior estudo de acadêmicos e cirurgiões dentistas. Foi realizada uma pesquisa de campo, exploratória e descritiva, com abordagem quanti-qualitativa, para descrição e análise do trajeto do V3 até a sua chegada no osso mandibular, assim como de estruturas que compõem a topografia adjacente a mesma utilizando uma hemiface intacta de um cadáver do sexo masculino no Laboratório de Anatomia Humana das Faculdades Nova Esperança, na cidade de João Pessoa. Devido à proximidade do nervo mandibular com o processo coronoide, fraturas nesta parte do osso mandíbula, podem ocasionar lesões no V3, além de traumas no osso temporal, e consequentemente de todo o gânglio trigeminal. Além destas, estruturas adjacentes como a glândula parótida, artérias maxilar e facial, ATM, e os nervos alveolar inferior, mentual e lingual, podem ser lesionadas em uma fratura mandibular. As lesões nestes nervos, podem resultar em redução grave da qualidade de vida e dor crônica, gerando desconfortos para o paciente. Diante do exposto fica evidente a importância de conhecer a anatomia topográfica da mandíbula e suas estruturas vasculonervosas, seu trajeto e a localização. Houve dificuldade na discussão devido à escassez da literatura em relação à temática proposta. Dessa forma, é necessário motivar novos estudos sobre a temática a fim de ampliar o conhecimento dos profissionais de saúde e estimular novas técnicas para diagnóstico precoce e melhorar os resultados terapêuticos, impactando positivamente na sobrevida de pacientes com fraturas de mandibulares(AU)


The mandibular nerve V3 is the third division of the trigeminal nerve, has motor and sensory fibers, being the mixed branch of this nerve. Its efferent branches are responsible for the motricity of the masticatory muscles, innervating the mylohyoid muscles, anterior belly of the digastric, soft palate tensor and tympanic tensor. Its afferent fibers are responsible for the sensitivity of the lower face and oral cavity, lower teeth, part of the tongue and proprioception of the capsule of the temporomandibular joint TMJ. The aim of this study is to explain the possible injuries to the mandibular nerve, its ramifications and adjacent structures in the case of mandible fractures, collaborating with detailed information for further study by academics and dentists. A field research, exploratory and descriptive, with a quantitative-qualitative approach, was carried out to describe and analyze the path of the V3 until its arrival in the mandibular bone, as well as structures that make up the topography adjacent to it using na intact hemiface of a male cadaver at the Human Anatomy Laboratory of Faculdades Nova Esperança, in João Pessoa city. Due to the proximity of the mandibular nerve with the coronoid process, fractures in this part of the mandible bone can cause injuries to the V3, in addition to trauma to the temporal bone, and consequently to the entire trigeminal ganglion. In addition to these, adjacent structures such as the parotid gland, maxillary and facial arteries, TMJ, and the inferior alveolar, mental and lingual nerves can be injured in a mandibular fracture. Damage to these nerves can result in severely reduced quality of life and chronic pain, causing discomfort for the patient. Given the above, the importance of knowing the topographic anatomy of the mandible and its vascular-nervous structures, its path and location is evident. There was difficulty in the discussion due to the scarcity of literature regarding the proposed theme. Thus, it is necessary to motivate further studies on the subject in order to expand the knowledge of health professionals and encourage new techniques for early diagnosis and improve therapeutic results, positively impacting the survival of patients with mandibular fractures(AU)

ABSTRACT

Abstract Introduction: Obstructive sleep apnea is characterized by a reduced airflow through the upper airways during sleep. Two forms of obstructive sleep apnea are described: the central form and the obstructive form. The obstructive form is related to many factors, such as the craniofacial morphology. Objective: To evaluate the correlation between the morphology of the cranial base, of the mandible and the maxilla, and obstructive sleep apnea severity. Methods: Eighty-four patients, mean age of 50.4 years old; 73 males and 11 females with obstructive sleep apnea were enrolled in the present study. Patients with high body mass index and comorbidities were excluded. Lateral cephalograms and polysomnography were collected for each patient to evaluate the correlation between craniofacial morphology and obstructive sleep apnea severity. A Spearman's rho correlation test between cephalometric measurements and obstructive sleep apnea indexes was computed. Statistical significance was set at p < 0.05. Results: Patients with a severe obstructive sleep apnea presented a reduction of sagittal growth of both effective mandibular length and cranio-basal length. The mandibular length was the only variable with a statistical correlation with apnea-hypopnea index. Vertical dimension showed a weak correlation with the severity of obstructive sleep apnea. No correlation with maxillary sagittal dimension was shown. Conclusion: Obstructive sleep apnea severity may be correlated to mandibular and cranial base growth. Facial vertical dimension had no correlation with obstructive sleep apnea severity.


Resumo Introdução: A apneia obstrutiva do sono é caracterizada por um fluxo de ar reduzido nas vias aéreas superiores durante o sono. Duas formas de apneia são descritas: a forma central e a forma obstrutiva. A forma obstrutiva tem sido relacionada a vários fatores, como a morfologia craniofacial. Objetivo: Avaliar a correlação entre a morfologia da base do crânio, da mandíbula e da maxila e a gravidade da apneia obstrutiva do sono. Método: Foram incluídos no presente estudo 84 pacientes com apneia obstrutiva do sono, com média de 50,4 anos; 73 homens e 11 mulheres. Pacientes com alto índice de massa corpórea e comorbidades foram excluídos. Foram coletados cefalogramas laterais e polissonografia para cada paciente para avaliar a correlação entre a morfologia craniofacial e a gravidade da apneia. Foi computado o coeficiente de correlação de postos de Spearman (rho) entre medidas cefalométricas e índices de apneia obstrutiva do sono. A significância estatística foi estabelecida em p < 0,05. Resultados: Pacientes com apneia obstrutiva do sono grave apresentaram redução do crescimento sagital do comprimento mandibular efetivo e do comprimento crânio-basal. O comprimento mandibular foi a única variável que apresentou correlação estatística com o índice de apneia-hipopneia. A dimensão vertical mostrou uma fraca correlação com a gravidade da apneia. Não foi demonstrada correlação com a dimensão maxilar sagital. Conclusão: A gravidade da apneia obstrutiva do sono pode estar correlacionada ao crescimento da base mandibular e craniana. A dimensão facial vertical não apresentou correlação com a gravidade da apneia.

ABSTRACT

PURPOSE@#The main aim is to provide clinical reference for the application of mini suture anchor in the reduction and fixation of displaced temporomandibular joint (TMJ) disc with intracapsular condylar fracture.@*METHODS@#From October 2018 to October 2019, 21 patients (31 sides) with intracapsular condylar fractures and articular disc displacement from West China Hospital of Stomatology, Sichuan University were included. The selection criteria were: (1) mandibular condylar fractures accompanied by displacement of the TMJ disc, confirmed by clinical examination, CT scan and other auxiliary examinations; (2) indication for surgical treatment; (3) no surgical contraindications; (4) no previous history of surgery in the operative area; (5) no facial nerve injury before the surgery; (6) informed consent to participate in the research program and (7) complete data. Patients without surgical treatment were excluded. The employed patients were followed up at 1, 3, 6 and 12 months after operation. Outcomes were assessed by success rate of operation, TMJ function and radiological examination results at 3 months after operation. Data were expressed as number and percent and analyzed using SPSS 19.0.@*RESULTS@#All the surgical procedures were completed successfully and all the articular discs were firmly attached to the condyles. The articular disc sufficiently covered the condylar head after the fixation. The fixation remained stable when the mandible was moved in each direction by the surgeons. No complications occurred. The functions of the TMJ were well-recovered postoperatively in most cases. CT scan revealed that the screws were completely embedded in the bone without loosening or displacement.@*CONCLUSION@#Mini suture anchor can provide satisfactory stabilization for the reduced articular disc and also promote the recovery of TMJ functions.

ABSTRACT

ABSTRACT Introduction: Orthodontic mini-implants (MI) are a reliable alternative to provide temporary orthodontic anchorage. Prior to miniscrew insertion, the best approach would be to evaluate each possible insertion site and measure the cortical bone thickness, and verify whether it would provide adequate primary stability. Objective: This study aimed to evaluate the difference in cortical bone thickness in areas of mini-implants insertion in patients of different ages, by means of cone beam computed tomography (CBCT). Methods: The sample of this retrospective study was composed of 123 CBCT scans, which were used to measure cortical bone thickness in the buccal and palatal inter-radicular space in the mesial region of the first permanent molars. These measures were compared by using the Student's t-test, ANOVA/Tukey tests, and Linear regression between male and female subjects, from 12 to 30 years old. Results: No significant difference was found in cortical bone thickness between sex, race and sagittal facial patterns. Significantly higher measurement values were observed in patients older than 12 years of age at all sites evaluated. The coefficient β at the adjusted linear regression analysis showed that at each increment in age, mean cortical thickness values increased by 0.06mm in the mandible, 0.03mm in the buccal region and 0.02mm in the palatal region of the maxilla. Conclusions: The increase in cortical bone thickness was positively associated with age; that is, the more advanced the patient's age was, the less chance there was of failure due to primary stability.


RESUMO Introdução: Os mini-implantes ortodônticos (MI) são uma alternativa confiável para fornecer ancoragem esquelética temporária. Antes da inserção do mini-implante, a melhor abordagem seria avaliar cada local de inserção possível, medir a espessura do osso cortical e verificar se proporcionaria uma adequada estabilidade primária. Objetivo: O presente estudo teve como objetivo avaliar a diferença na espessura do osso cortical em áreas de inserção dos mini-implantes em pacientes de diferentes idades, por meio da tomografia computadorizada de feixe cônico. Métodos: A amostra desse estudo retrospectivo foi composta por 123 tomografias computadorizadas de feixe cônico, que foram utilizadas para medir a espessura do osso cortical nos espaços inter-radiculares vestibular e palatino na região mesial dos primeiros molares permanentes. Essas medidas foram comparadas por meio dos testes t de Student, ANOVA/Tukey e regressão linear entre os sexos masculino e feminino, de 12 a 30 anos. Resultados: Não houve diferença estatisticamente significativa na espessura cortical, quando comparados sexo, cor da pele e padrão facial sagital. Foram verificadas medidas significativamente maiores em pacientes com idade superior a 12 anos em todos os sítios avaliados. O coeficiente β da análise de regressão linear ajustada mostrou que, a cada incremento da idade, os valores médios da espessura cortical aumentaram 0,06 mm na mandíbula, 0,03 mm na região vestibular e 0,02 mm na região palatina da maxila. Conclusão: O aumento da espessura do osso cortical teve associação positiva com a idade, ou seja, quanto mais avançada a idade do paciente, menor a chance de falha, devido à estabilidade primária.

ABSTRACT

Mandibular aggressive central giant cell granuloma is a rare non-neoplastic giant cell tumour characterised by pain, bone destruction, tooth root resorption, jawbone cortical perforation, and high recurrence rate. This is a case of a 10-year-old boy who presented to the Dental Surgical outpatient clinic of University of Uyo Teaching Hospital with a three-year history of left jaw swelling. The clinical diagnosis was fibrous dysplasia of the left hemi-mandible. Consequently, left hemi-mandibulectomy was performed, and subsequent histopathological diagnosis was aggressive central giant cell granuloma of the mandible. This article presents this rare diagnosis and explores its classification, aetiopathogenesis, clinico-pathological features and management.

ABSTRACT

Forensic physical anthropometry allows the determination of animal species and estimates sex, ancestry, age and height. Aim: To analyze the effectiveness of a cranioscopic/ morphological evaluation for sex estimation with a sample of the Brazilian mixed-race population by conducting a qualitative visual assessment without prior knowledge of sex. Methods: This is a blind cross-sectional study that evaluated 30 cranial characteristics of 192 skulls with mandible, 108 male and 84 female individuals, aged 22 to 97 years, from the Osteological and Tomographic Biobank. The qualitative characteristics were classified and compared to the actual sex information of the Biobank database. The statistical analysis was used to calculate de Cohen's kappa coefficient, total percentage of agreement, sensitivity and specificity of visual sex classification. Results: Of the 30 cranial variables analyzed, 15 presented moderate degree of agreement, achieving value of Kappa test between 0.41­0.60: Glabella (Gl), Angle and lines (At), Mental eminence (Em), Mandible size (Tm), Cranial base (Bc), Mouth depth (Pb), Nasal aperture (Anl), Supraorbital region (Rs), Orbits (Orb), Mastoid processes (Pm), Alveolar arches (Aa), Zygomatic arch (Az), Orbital edge (Bo), Supraorbital protuberances (Pts), and Supramastoid crests and rugosity (Crsm). The Facial physiognomy (Ff) presented substantial reliability (0.61-0.80) with 89.8% sensitivity for male sex and 70.2% specificity. Conclusions: Cranial morphological characteristics present sexual dimorphism; however, in this study only 15 variables showed moderate degree of agreement and can be used in sex estimation. Only one variable (Ff) 81.2% total agreement with substantial reliability. Quantitative methods can be associated for safe sex estimation

ABSTRACT

Objetivos: Demostrar la utilidad y la facilidad técnica del injerto tibial en defectos óseos orales y maxilofaciales, para tenerlo como un recurso alternativo en la práctica general del cirujano oral y maxilofacial. Caso clínico: Se presenta un caso clínico con el uso de injerto óseo autólogo de tibia para el relleno de un defecto óseo a raíz de una lesión quística. Se realizó la exéresis de la patología quística por medio de un abordaje oral y posteriormente se recolectó hueso medular tibial a través de un abordaje medio al tubérculo anterior de la tibia, para poder colocarlo en el defecto óseo. Conclusión: El injerto de hueso medular de epífisis tibial representa un sitio de recolección de fácil acceso, del que se puede obtener una cantidad de hueso ideal para defectos de pequeño y mediano tamaño de la región maxilofacial, de baja morbilidad y con muy pocas complicaciones post-operatorias, lo que lo convierte en una alternativa para rellenos de cavidades óseas de gran utilidad (AU)


Objective: To demonstrate the utility and technical ease of the tibial graft in oral and maxillofacial bone defects so as to have it as an alternative resource in the general practice of the oral and maxillofacial surgeon. Case report: A clinical case is shown with the use of an autologous tibial bone graft to fill a bone defect as a result of a cystic lesion. The cyst was excised by an oral approach and the medial tibial bone was collected through a middle approach to the anterior tubercle of the tibia, to place it in the bone defect. Conclusion: The tibial epiphysis medullary bone graft represents an easily accessible collection site, from which an ideal amount of bone can be obtained for small and mediumsized defects of the maxillofacial region, with low morbidity and very few post-operative complications, which makes it a useful option for bone cavity filling (AU)

ABSTRACT

Este trabajo de investigación tiene como finalidad comparar la inclinación del incisivo inferior pre y post-tratamiento en pacientes tratados ortodóncicamente con técnicas Roth y técnica Damon a los cuales no se les realizó exodoncias. El grupo de estudio estuvo conformado por 150 pacientes adultos con dentición permanente completa que han sido atendidos en el Círculo Argentino de Odontología. Para medir la inclinación se utilizó la fórmula de Tweed: ángulo IMPA, eje axial del incisivo inferior con el plano mandibular. Los valores tomados de los trazados pre y post-tratamiento fueron sometidos a un test de Student apareado utilizando el programa Infostat v 2010. Se encontró una diferencia significativa en la inclinación axial del incisivo inferior post tratamiento cualquiera sea la técnica utilizada, aumenta en ambos casos. No se realizó discriminación de torques (Roth ­ 1°, Damon torque estándar ­ 3°, Damon bajo torque - 11°) (AU)


This research work aims to compare the inclination of the lower incisor before and after treatment in patients treated orthodontically with Roth techniques and Damon technique to which no exodontics were performed. The study group consisted of 150 adult patients with complete permanent dentition who have been treated in Circulo Argentino de Odontología. To measure the inclination the Tweed formula was used: IMPA angle, axial axis of the lower incisor with the mandibular plane. The values taken from the pre and post-treatment plots were subjected to a Student test paired using the Infostat v 2010 program. A significant difference was found in the axial inclination of the lower incisor post treatment whatever the technique used, it increases in both cases. No torques discrimination was performed (Roth - 1 °, Damon standard torque - 3 °, Damon under torque - 11 °) (AU)

ABSTRACT

Abstract This study aimed to estimate cost and compatibility with public financial incentives of two technologies for treating the edentulous mandible: lower complete dentures (CD) and overdentures retained by two dental implants (OD). This study consisted of a partial economic evaluation, with a micro-costing bottom-up approach for the calculation of direct costs. The estimates involved the number of consultations, proportion of materials, equipment, instruments' lifetime, and human resources, described in the price panel website of the Ministry of Economy in Brazil. Complementary information was obtained from a panel of experts. A sensitivity analysis was based on 20% variation. The estimated cost of a CD was R$ 189.89 (base scenario), and this varied between R$ 151.91 and R$ 227.89 according to sensibility analysis. The cost of an OD was R$ 663.05 (ranging from R$ 795.66 to R$ 530.44 - 1US=R$ 3.80/July 2019). The Ministry of Health covers appropriately the costs of the CD and OD. Both technologies showed costs that are within the limits of financial public incentives obtained by municipalities. The technologies are economically viable and should be induced through public policies due to their positive impacts on several functional domains of health.


Resumo Estimar os custos e a compatibilidade dos incentivos públicos de duas tecnologias para o tratamento da mandíbula edêntula: prótese total convencional (PTC) e overdenture retida por dois implantes (OD). Este estudo consistiu em uma avaliação econômica parcial, com abordagem "bottom-up" para o cálculo dos custos diretos. As estimativas levaram em consideração o número de consultas, proporção de materiais, equipamentos, vida útil dos instrumentais e recursos humanos. Os custos foram baseados no painel de preços do Ministério da Economia do Brasil e informações complementares foram obtidas de um painel de especialistas. Uma análise de sensibilidade foi baseada na variação de 20% dos custos. Os custos da PTC foram estimados em R$ 189,89 (cenário base) com variação entre R$ 151,91 e R$ 227,89 na análise de sensibilidade. Os custos da OD foram R$ 663,05 (variando de R$ 795,66 a R$ 530,44). O Ministério da Saúde cobre apropriadamente os custos de ambas as tecnologias nos cenários base e mais otimista. Ambas as tecnologias apresentaram custos dentro dos limites dos incentivos públicos recebidos. As tecnologias são economicamente viáveis e devem ser induzidas por políticas públicas diante do impacto positivo em vários domínios funcionais da saúde.

ABSTRACT

Introducción: El crecimiento de los tejidos esqueléticos constituye una respuesta secundaria, compensatoria y mecánicamente obligada a cambiar las matrices funcionales. Cuando por alguna razón las matrices funcionales se ven afectadas en su crecimiento, los tejidos esqueléticos responden también con un grado de afectación dependiendo del momento en que esta se produzca. Entonces la mandíbula como parte del viscerocráneo debe presentar esa relación con el hueso hioides de forma directa. Objetivos: Asociar el comportamiento morfológico del hueso hioides con variables morfológicas de la mandíbula y verificar sí la morfología de los huesos pertenecientes a los esqueletos estudiados está determinada por el conjunto de tejidos blandos que los rodea y marcan el ritmo del proceso de remodelación de crecimiento. Material y Métodos: Se realizó la continuación del estudio osteológico en una muestra ósea de 82 esqueletos con mediciones morfométricas del hueso hioides y la mandíbula. Para evaluar la relación de la morfología del hueso hioides con respecto a la mandíbula, se utilizaron matrices de coeficiente de correlación lineal de Pearson en SPSS versión 22 de Window. Resultados: Se corrobora la relación de la morfología del hueso hioides con el crecimiento del viscerocráneo, debido a la correlación positiva y significativa entre varias variables morfológicas del hioides que se obtuvo, -tanto a nivel de su cuerpo como sus astas o cuernos mayores-, con la mandíbula. Conclusiones: Existe una asociación de la morfología del hueso hioides con respecto a la morfología de la mandíbula(AU)


Introduction: The growth of skeletal tissues constitutes a secondary, compensatory and mechanically obliged response to change the functional matrixes. When the growth of functional matrixes is affected for any reason, the skeletal tissues also respond with a degree of affectation depending on the moment in which it occurs. Then the mandible, as part of the viscerocranium, must present that relationship with the hyoid bone directly. Objective: To associate the morphological behavior of the hyoid bone with the morphological variables of the mandible and verify if the morphology of the bones belonging to the skeletons studied is determined by the set of soft tissues that surround them and set the pace of the growth remodeling process. Material and Methods: The continuation of the osteological study was carried out in a bone sample of 82 skulls by performing morphometric measurements of the hyoid bone and the mandible. Pearson's linear correlation coefficient matrices in SPSS Version 22 were used to evaluate the relationship between the morphology of the hyoid bone and the bones of the mandible. Results: The relationship between the morphology of the hyoid bone and the growth of the viscerocranium is corroborated by the positive and significant correlation between several morphological variables of the hyoid bone obtained - both at the level of its body and its greater horns -, and the mandible. Conclusions: These findings corroborate the association between the morphology of the hyoid bone and the growth of the mandible(AU)

ABSTRACT

Background: It is essential that the dentist understand the positional variations of the mental foramen to perform different types of dental procedures. This study was conducted to identify the position of the mental foramen among the Saudi population of Al Hasa. Material and Methods: According to the selection criteria of 200 CBCT images, 101 images were selected. The selected images were categorized into five groups with respect to patient age. Each image was evaluated from both sides of the mandible and then recorded in six classes (position I-VI) according to the horizontal position and three classes in the vertical position. Results: In the Saudi Al Hasa population, Type 4 (at the level of 2ndpremolar) was the most common location for mental foramen in the horizontal direction, on the right side (n= 41; 40.6%) and on the left side (n=44; 43.6%). Mental foramen was found in the vertical location, Type 3 (below the apex of 1st and 2nd premolars) was found in the right side (n= 54; 53.5%) and left side (n=56; 55.4%). The position of mental foramen is not constant and changes according to gender and ethnicity. This warrants dentists to evaluate patients individually. Conclusion: Even though the present study was done with a small sample of patients it provides a picture about approximate location of mental foramen among the target group of a population.


Antecedentes: Es esencial que el dentista comprenda las variaciones posicionales del agujero mentoniano para realizar diferentes tipos de procedimientos dentales. Este estudio se realizó para identificar la posición del foramen mental entre la población saudita de Alhasa. Material y Métodos: De acuerdo con los criterios de selección de 200 imágenes CBCT, se seleccionaron 101 imágenes. Las imágenes seleccionadas se categorizaron en cinco grupos con respecto a la edad del paciente. Cada imagen se evaluó desde ambos lados de la mandíbula y luego se registró en seis clases (posición I-VI) según la posición horizontal y tres clases en la posición vertical. Resultados: En la población saudita de Al Hasa, el tipo 4 (al nivel del segundo premolar) fue la ubicación más común para el foramen mental en la dirección horizontal, en el lado derecho (n = 41; 40,6%) y en el lado izquierdo (n = 44; 43,6%). El foramen mental se encontró en la ubicación vertical, el Tipo 3 (debajo del ápice del 1er y 2do premolares) se encontró en el lado derecho (n = 54; 53,5%) y el lado izquierdo (n = 56; 55,4%). La posición del foramen mental no es constante y cambia según el género y la etnia. Esto justifica que los dentistas evalúen a los pacientes individualmente. Conclusión: Aunque el presente estudio se realizó con una pequeña muestra de pacientes, proporciona una imagen sobre la ubicación aproximada del foramen mental entre el grupo objetivo de una población.
