ABSTRACT
A osteonecrose dos maxilares induzida por medicamentos (MRONJ) caracteriza-se por exposição óssea ou osso que pode ser sondado através de fístula intra ou extraoral, em região maxilofacial, e que não cicatriza dentro de oito semanas. A MRONJ é uma condição rara e debilitante que pode causar dor, disfagia e odor desagradável na cavidade oral, afetando pacientes com histórico ou sob uso contínuo de terapia antirreabsortiva, isolada ou associada a imunomoduladores ou drogas antiangiogênicas, mas sem histórico de radioterapia nos maxilares. O objetivo desta revisão narrativa de literatura é compilar os principais aspectos sobre a etiopatogenia da MRONJ e as opções terapêuticas disponíveis. A etiologia da MRONJ é multifatorial, complexa, e não está totalmente compreendida, não havendo um tratamento definitivo, mas diversas modalidades terapêuticas que visam o controle da dor e da progressão da osteonecrose. Conclui-se com essa revisão que o entendimento da etiopatogenia da MRONJ pelo cirurgião-dentista lhe permite adotar medidas preventivas, bem como o conhecimento das modalidades terapêuticas disponíveis lhe possibilita oferecer o manejo adequado para seu paciente, conforme o estágio da doença.
Medication-related osteonecrosis of the jaw (MRONJ) is characterized by exposed bone or bone that can be probed through an intra or extraoral fistula, in the maxillofacial region, which does not heal within eight weeks. MRONJ is a rare and debilitating condition that can cause pain, dysphagia and unpleasant odor in the oral cavity, affecting patients with a history or continuous use of antiresorptive therapy, alone or associated with immunomodulators or antiangiogenic drugs, but without a history of radiotherapy to the jaws. The aim of this narrative literature review is to compile the main aspects about the etiopathogenesis of MRONJ and the available therapeutic options. The etiology of MRONJ is multifactorial, complex, and is not fully understood, with no definitive treatment, but several therapeutic modalities that aim to control pain and the progression of osteonecrosis. It is concluded from this review that the understanding of the etiopathogenesis of MRONJ by the dental surgeon allows him to adopt preventive measures, as well as the knowledge of the therapeutic modalities available allows him to offer the appropriate management for his patient, depending on the stage of the disease.

Osteonecrosis of the jaw associated with bisphosphonate use is a matter of utmost importance in clinical practice for the safe treatment of patients using this medication. Objective: The aim of this study was to evaluate the level of knowledge of dentists who carry out clinical practice about bisphosphonate-associated jaw osteonecrosis. Material and Methods: The methodology used in the present research consisted of a non-probability sampling approach for the selection of participants. To conduct the study, a questionnaire created on the Google Forms platform was sent via Direct on Instagram to the professionals who agreed to participate. The data were sent for analysis, using the frequency for each response, and the professionals were divided into subcategories according to their time of professional practice. Results: Participants were familiar with the purpose of the medication (65%) or had heard of it (34%); regarding the professionals' opinion on their knowledge and practice about bisphosphonate-related osteonecrosis a significant percentage (93.24%) responded positively regarding the existence of side effects resulting from the therapeutic use of bisphosphonates and 48.65% self-evaluated their level of knowledge on the subject as insufficient. Conclusion: The study reveals that almost all participating dentists have good knowledge about the effects caused by bisphosphonates, but some of them still do not feel specifically confident about the management and knowledge of jaw osteonecrosis (AU)

Abstract Objective: To evaluate the utility of panoramic radiographs in pre-prosthetic screening of edentulous arches. Material and Methods: Panoramic radiographs taken for three years were retrospectively analyzed. Observations from the radiographs shall be categorized and classified into either of the two categories, namely: 'findings with minimal impact on denture fabrication' and 'findings which affect denture fabrication and require further evaluation.' Anatomic variations, jaw pathologies, and residual ridge resorption patterns were assessed. Results: This study included the initial screening of 23,020 panoramic radiographs, out of which 505 (showing either one or both edentulous arches) were included for the study purpose. The age range of the subjects was from 21 to 94 years. 52.6% of the radiographs showed positive findings. More than half of the radiographs belonged to the males (52.5%). Hyperpneumatization of the maxillary sinus, crestal position of the mental foramen, and retained root fragments were the most common entities noted in the radiographs. Changes in the mental foramen were significantly higher in males than females (p=0.002). Conclusion: Observations from this study showed that panoramic radiographs have high utility for screening edentulous arches, and they should be used in routine clinical practice before denture fabrication.

Introduction: We report findings that allow us to observe the impacted maxillary canine as an entity of important prevalence. In the province of Ciego de Avila there is little research published on this eruptive alteration. Objectives: To describe epidemiological and clinical variables and to identify the local factors present in pediatric patients with retained maxillary canines in the municipality of Ciego de Avila between October 2019 and June 2020. Methods: An analytical observational research of cases and controls was carried out to determine the local factors associated to maxillary canine retention. The study population consisted of 388 schoolchildren between the ages of 11 and 17 years old, belonging to the health area of the Dr. Luis Páez Alfonso Stomatological Teaching Clinic in the municipality of Ciego de Avila, during the study period. Results: 56.9 percent of the participants belonged to the female sex; the group of 11 to 13 years old prevailed with 70.7 percent and the skin color was white (74.1 percent). A total of 56.9 percent of the patients had bilateral retention and the highest percentage (60.4 percent) was located in the vestibular region. Negative bone-tooth discrepancy, transverse micrognathism (OR of 6.3) and premature loss of primary teeth (OR was 6.1) showed significant statistical significance. Conclusions: Maxillary canine retention predominated in the female sex, in the 11 to 13 years age group, and in white-skinned pediatric patients. Bilateral retention and vestibular location of the canines occurred more frequently. The association between maxillary canine retention and the local factors negative bone-tooth discrepancy, transverse micrognathism and premature loss of primary teeth was found(AU)

The microscopical diagnosis of radicular cyst (RC) is straightforward; nonetheless, in some cases with unusual histopathological features, strict clinicopathological correlation is necessary to achieve the correct diagnosis. We report a case of a 5-year-old girl was referred presenting extensive carious lesion in the tooth #55, associated with vestibular sinus tract. Medical history revealed allergic asthma diagnosis. After clinical and imagi-nological exams, the deciduous tooth was extracted. Microscopically, the soft tissue lesion attached to the root showed typical RC features; however, in the cystic capsule, lymphoid follicles and vascular networks (lined by epithelioid endothelial cells) surrounded by nu-merous eosinophils, were observed. Immunohistochemistry, through CD3, CD20, CD34 and alpha-smooth muscle actin antibodies, highlighted these findings. Moreover, CD1a and CD207 were negative. To the best of our knowledge, this is the first report of RC showing angiolymphoid hyperplasia with eosinophilia (ALHE)-like features. (AU)

Introduction: Tapered implants have shown that thanks to their macro design they are capable of expanding the surgical bed performed by the surgeon, which in clinical practice gives a feeling of greater stability, however it is highly subjective and dependent on the operator. Aim: To analyze the influence of the implant macro design in the primary and secondary stability by means of analysis of resonance frequency and force of insertion. Methods: 38 Screw Type and Tapered Type implants were placed in 18 patients in the Bucomaxillofacial Implantology program of the University of Chile during 2006 and 2007 in type II or III bone jaws according to Leckholm and Zarb. Implant stability, implant stability coefficient (ISQ), was measured through Ostell® mentor at the time of installation (ISQ1) and then at connection (ISQ2) and the Insertion Torque through the Osseoset® machine: 17 Screw Type implants with an approximate average contact area of 237 mm2 (3.75/15 mm; 3.75/13 mm) and 17 Tapered Type implants with an approximate average contact area of 226 mm2 (4.3/13 mm; 4.3/16 mm). Results: The averages of ISQ1 and ISQ2 and Insertion Torque respectively for implants with an approximate contact area of 237 mm2 were 71.3 ISQ1, 66.6 ISQ2 and 44.52 Ncm; for 226 mm2 implants it was 75 ISQ1, 72.5 ISQ2 and 48.82 Ncm. Conclusion: Implants with an average contact area of approximately 226 mm2 (Tapered Type) present significantly higher primary and secondary stability than those with an average contact area of approximately 237 mm2 (Screw Type). (Average ISQ1: p = 0.0473; Insertion Torque: p = 0.0031 and Average ISQ2: p = 0.0039)(AU)
Introducción: Los implantes Cónicos han demostrado que gracias a su macro diseño son capaces de expandir el lecho quirúrgico realizado por el cirujano, lo que en la práctica clínica da una sensación de mayor estabilidad, sin embargo, ella es altamente subjetiva y dependiente del operador. Objetivo: Analizar la influencia del diseño del implante en la estabilidad primaria y secundaria mediante análisis de frecuencia de resonancia y Torque de Inserción. Métodos: 38 implantes Tipo Tornillo y Tipo Cónico fueron colocados en 18 pacientes en el programa de Implantología Bucomáxilofacial de la Universidad de Chile durante el año 2006 y 2007 en maxilares de hueso tipo II o III según Leckholm y Zarb.

El segundo conducto mesiovestibular en las raíces mesiovestibulares de los molares maxilares es un hallazgo frecuente en los tratamientos de conducto radicular. El segundo molar superior tiene el sistema de conductos radiculares más complejo de todos los molares. La falla en la ubicación de estos canales se asocia con una alta tasa de tratamientos fallidos de los molares maxilares y un alto porcentaje de fracasos del tratamiento se debe a la imposibilidad de localizar, instrumentar y obturar el segundo conducto mesiobucal (MB2). Si bien la anatomía de estos dientes está bien definida en los estudios de microtomografía computarizada, el manejo clínico es un gran desafío para el odontólogo. En general, los conductos faltantes son la segunda causa más importante de fracaso, siendo incluso más relevantes que las complejidades anatómicas. El MB2 comienza desde la cámara pulpar en una pendiente mesial empinada y luego se dobla hacia atrás distalmente, lo que hace que su detección y negociación sea un desafío. La incapacidad para detectar y tratar este canal es la razón de muchos fracasos endodónticos, ya que existe una alta incidencia de localización de estos canales en casos de retratamiento seguido de cicatrización sin complicaciones. Con el avance de los años la magnificación, los aditamentos ultrasónicos y los nuevos instrumentos mecanizados han ayudado a encontrar conductos accesorios mejorando el pronóstico y tratamiento.
The second mesiobuccal canal in the mesiobuccal roots of the maxillary molars is a frequent finding in root canal treatments. The upper second molar has the most complex root canal system of all molars. Failure to locate these canals is associated with a high rate of failed treatment of maxillary molars, and a high percentage of treatment failure is due to the impossibility of locating, instrumenting, and obturating the second mesiobuccal canal (MB2). Although the anatomy of these teeth is well defined in microcomputed tomography studies, clinical management is a great challenge for the dentist. In general, missing ducts arethe second most important cause of failure, being even more relevant than anatomical complexities. MB2 starts from the pulp chamber on a steep mesial slope and then bends back distally, making detection and negotiation challenging. The inability to detect and treat this canal is the reason for many endodontic failures, since there is a high incidence of localization of these canals in cases of retreatment followed by healing without complications. Over the years, magnification, ultrasonic attachments, and new mechanized instruments have helped to find accessory canals, improving prognosis and treatment.

As exostoses mais conhecidas são o Torus palatino e mandibular, que se desenvolvem a partir do crescimento benigno da cortical óssea, localizadas respectivamente na linha média palatina e superfície lingual de caninos e pré-molares, podendo ser unilaterais ou bilaterais. Esse trabalho tem como objetivo o estudo de um grupo familiar que apresentaram o Torus como característica em comum, buscando confirmar a presença e prevalência das características clínicas multifatoriais listadas na literatura, possibilitando o diagnóstico da etiologia e assim traçando um plano de tratamento individual, se necessário. Como metodologia, foi realizada uma triagem com cada membro familiar na clínica Odontológica da Faculdade Sete Lagoas - FACSETE, descartando a participação no estudo os membros que não apresentaram o Torus. Os indivíduos que apresentaram indicação da remoção cirúrgica foram encaminhados para clínica de cirurgia da própria instituição. Concluímos, portanto, com este estudo que fatores genéticos e ambientais colaboram como fator etiológico mais predominantes para surgimento do Torus no grupo familiar estudado... (AU)
The best known exostosis are the palatine and mandibular Torus, which develop from the benign growth of the cortical bone, located respectively in the midpalatal line and lingual surface of canines and premolars, and maybe unilateral or bilateral. This work aims to study a family group that had Torus as a common feature, confirming the presence and prevalence of multifactorial clinical features listed in the literature, enabling the diagnosis of etiology and thus outlining an in dividual treatment plan, if necessary. As a methodology, a screening was performed by each family member at the Dental Clinic of Facul dade Sete Lagoas - FACSETE, discarding the participation in the study for members who did not present Torus. Individuals who indicated surgical removal were referred to the institution's own surgery clinic. Therefore, we conclude with this study that genetic and environmental factors collaborate as the most predominant etiological factor for the emergence of Torus in the studied family group... (AU)

Introdução: O linfoma de Burkitt é um linfoma altamente agressivo do tipo não-hodgkin originado a partir de mutação nos linfócitos B. Clinicamente demonstra características de malignidade como evolução rápida, destruição das corticais ósseas e mobilidade dentária, além de aumento de volume facial adjacente aos ossos maxilares. Esse tumor é de difícil diagnóstico devido às características clínicas inespecíficas, o que pode muitas vezes levar a um diagnóstico e tratamento tardio, piorando o prognóstico e a taxa de sobrevida do paciente. Relato de Caso: O caso clínico se trata de uma paciente, sexo feminino, 21 anos de idade, com história de aumento de volume em hemiface esquerda de evolução repentina, associada a dor, febre e relato de exodontia recente. A história clínica e os achados clínicos inespecíficos simularam uma infecção odontogênica, a qual atrasou o diagnóstico e o tratamento correto. Após exames imaginológicos específicos, exploração cirúrgica e exame histopatológico foi possível chegar a um diagnóstico definitivo de linfoma de Burkitt e manejo adequado dessa patologia.

Introduction: Burkitt's lymphoma is a highly aggressive non-Hodgkin type lymphoma originated from a mutation in B lymphocytes. It clinically demonstrates malignant characteristics such as rapid evolution, destruction of bone corticals and tooth mobility, in addition to increased facial volume adjacent to the maxillary bones. This tumor is difficult to diagnose due to its nonspecific clinical characteristics, which can often lead to a late diagnosis and treatment, worsening the patient's prognosis and survival rate. Case Report: The clinical case is a female patient, 21 years old, with a history of swelling in the left hemiface of sudden evolution, associated with pain, fever and a report of recent extraction. Clinical history and nonspecific clinical findings simulated an odontogenic infection, which delayed diagnosis and correct treatment. After specific imaging exams, surgical exploration and histopathological examination, it was possible to reach a definitive diagnosis of Burkitt's lymphoma and adequate management of this pathology. Conclusion: The role of dentists in the early detection of this pathology with involvement of the jaws is extremely important, since remission and/or cure depends on the extent of the disease, its biological behavior and the time of diagnosis...

RESUMEN: La osteonecrosis también conocida como una necrosis avascular del hueso, es una condición degenerativa producida por la pérdida en la irrigación sanguínea, debido a la toxicidad directa en los tejidos óseos provocadas por quimioterapia, radioterapia, daño térmico, fumar y en la última década con la aparición de medicamentos como los bifosfonatos (BF), denosumab y medicamentos antigiogénicos, con los cuales hemos ido conociendo más sobre esta patología. La principal hipótesis de la fisiopatología de esta enfermedad es la inhibición de la angiogénesis, pero también se considera como hipótesis la toxicidad de los tejidos blandos o la disfunción adquirida de la inmunidad. En el año 2003 fue relatada por primera vez la relación entre BF y osteonecrosis maxilar (ONM). Ese mismo año fue descrito que pacientes con mieloma múltiple que recibían pamidronato podrían desarrollar necrosis avascular de los maxilares. Otras publicaciones informaban sobre pacientes que requerían tratamiento para necrosis ósea intra-oral de ocurrencia espontánea después de extracciones dentales o trauma oral. La primera denominación a esta patología fue (BRONJ) por sus siglas en inglés, se refería a ONM relacionada a BF. En 2014 la Asociación Americana de Cirujanos Orales y Maxilofaciales (AAOMS) publicó una nueva definición (position paper) renombrándolo como MRONJ (osteonecrosis de los maxilares relacionada a medicamentos) ONMRM. El rol en la identificación de pacientes con riesgo de ONMRM es fundamental. Los estudios han demostrado que el riesgo de desarrollar la afección se puede reducir sustancialmente si los pacientes son evaluados por un profesional dental y se toman medidas preventivas. La presente revisión narrativa realiza un recorrido desde la historia, los medicamentos involucrados, y diferentes estrategias de tratamientos propuestos, haciendo hincapié en la conducta que debemos seguir los cirujanos dentistas para enfrentar estos casos de forma temprana y prevenir su evolución.
ABSTRACT: Osteonecrosis is also known as avascular necrosis of the bone, it is a degenerative condition produced by the loss of blood flow, due to direct toxicity in the bone tissues caused by chemotherapy, radiotherapy, thermal damage, smoking and in the last decade with the arrival of drugs such as bisphosphonates (BP), denosumab and antigiogenic drugs we have been learning more about this pathology. The main hypothesis of the pathophysiology of this disease is the inhibition of angiogenesis, but soft tissue toxicity or acquired immunity dysfunction are also considered as hypotheses. In 2003, the relationship between BP and osteonecrosis of the jaws (ONJ) was reported for the first time. In the same year it was described that multiple myeloma patients receiving pamidronate could develop avascular necrosis of the jaws. Other publications reported about patients requiring treatment for spontaneously intra-oral bone necrosis after dental extractions or oral trauma. The first name for this pathology was (BRONJ) for its English acronym, it referred to ONJ related to BF. In 2014 the American Association of Oral and Maxillofacial Surgeons (AAOMS) published a new definition (position paper) renaming it MRONJ (drug-related osteonecrosis of the jaws) ONMRM. The role of identifying patients at risk of ONMRM is fundamental. Studies have shown that the risk of developing the condition can be substantially reduced if patients are evaluated by a dental professional and preventive measures are taken Exposure of bone or fistula that can be probed down to the bone in the maxillofacial region that persists for more than 8 weeks, with these conditions it is considered that there is a diagnosis of ONMRM This narrative review takes a journey from history, the drugs involved, and different proposed treatment strategies, emphasizing the behavior that dental surgeons must follow to face these cases early and prevent their evolution.

Medication-related osteonecrosis of the jaw (MRONJ) is a serious adverse event related to administration of antiresorptive or antiangiogenic medications. With the increasing usage of bone-modifying agents in cancer therapy, the incidence of MRONJ enhanced gradually, which affects the life quality of patients and interferes with cancer therapy. In 2019, Multinational Association of Supportive Care in Cancer (MASCC), International Society of Oral Oncology (ISOO) and American Society of Clinical Oncology (ASCO) convened a multidisciplinary Expert Panel to evaluate the evidence and formulate recommendations on practices in the prevention and management of MRONJ in patients with cancer. The present article made an interpretation of Medication-Related Osteonecrosis of the Jaw: MASCC/ISOO/ASCO Clinical Practice Guideline so as to provide clinicians with diagnostic and therapeutic approaches for cancer patients with MRONJ.

Introdução: A osteorradionecrose dos maxilares (ORN) é uma conhecida complicação relacionada à radioterapia, tendo grande impacto e podendo acometer indivíduos submetidos a radioterapia para tratamento de câncer da cavidade oral associado a uma condição dental desfavorável. Objetivo: Este estudo teve como objetivo avaliar e determinar a influência de fatores sociodemográficos e clínicos associados à ORN em indivíduos com câncer de cavidade oral e orofaringe submetidos a radioterapia atendidos no Departamento de Odontologia do Hospital de Câncer de Barretos entre os anos de 2007-2017. Material e método: Trata-se de um estudo caso-controle com coleta de dados retrospectivos em prontuários. Resultado: Os dados coletados correspodem a 83 prontuários selecionados, sendo 31 correspondentes ao grupo caso e 52 correspondentes ao grupo controle. Evidenciou-se uma média (desvio padrão) de idade para indivíduos dos grupos caso e controle de 65,44 (7,49) e 65,02 (10,08), respectivamente. Em ambos os grupos houve predominância do sexo masculino. A média (desvio padrão) do intervalo entre a última sessão de radioterapia e a data do diagnóstico de ORN foi de 26,42 (27,51) meses. A presença de doença periodontal no diagnóstico [OR=6,253; (IC95%1,25-31,12; p=0,025)] e exodontia [OR = 6,148; (IC95%) 1,14-26,23; p= 0,014) após radioterapia resultou em uma maior chance de desenvolver a ORN. Conclusão: A partir dos resultados obtidos, conclui-se que os principais fatores de risco para desenvolvimento da ORN em indivíduos com câncer de cavidade oral e orofaringe são exodontia após radioterapia e presença de periodontite no diagnóstico.
Introduction: Osteoradionecrosis of the mandible (ORNM) is a well-known complication related to radiotherapy that can affect patients undergoing radiotherapy to treat oral cavity cancer associated with an unfavorable dental condition. Objective: This study aimed to assess and determine the influence of sociodemographic and clinical factors associated with osteoradionecrosis on patients with cancer of oral cavity and oropharynx undergoing radiotherapy treated at the Department of Dentistry of the Barretos Cancer Hospital between 2007- 2017. Materials and method: This is a case-control study with retrospective data collection from medical records. Result: The data were collected from 83 medical records, 31 corresponding to the case group and 52 corresponding to the control group. The patients in the case and control groups were aged in average (standard deviation) 65.44 (7.49) and 65.02 (10.08) years, respectively. Both groups had a predominance of male individuals. The mean (standard deviation) interval between the last radiotherapy session and the date of osteoradionecrosis diagnosis was 26.42 (27.51) months. The presence of periodontal disease at diagnosis [OR = 6,253; (95% CI 1.25-31.12; p = 0.025)] and tooth extraction [OR = 6.148; (95% CI) 1.14-26.23; p = 0.014] after radiotherapy resulted in greater chances of developing osteoradionecrosis. Conclusion: Based on our results, extraction after radiotherapy and the presence of periodontitis in the diagnosis of patients with cancer of oral cavity and oropharynx are the main risk factors for the development of osteoradionecrosis.

SUMMARY: The maxillary first premolar (MFP) presents a highly variable and complex root morphology; it is also one of the teeth most likely to suffer vertical root fractures. The aim of this study was to describe the morphology of the root and root canal system of the MFP in a Chilean population using Cone-Beam Computed Tomography (CBCT). One hundred and twenty-one MFP were evaluated (60 left and 61 right), belonging to subjects of both sexes. Descriptive and statiscal analysis of the data was carried out, with a value of P < 0.05 being statistically significant. One root was observed in 71 % of teeth and two roots in 29 %; statistically significant differences were observed in the number of roots by sex (p<0.05). Two root canals were found in 69.5 % of teeth and one canal in 30.5 %. In terms of morphological classification, 41.3 % of cases were Vertucci Type IV. The proximal cementodentinal walls were the thinnest. The MFP presented a high degree of morphological variation in a Chilean subpopulation.

Chewing is the first step in the digestion process in mammals. It is a highly coordinated process with a complex sensorimotor activity, the aim of which is to prepare foods for the formation of the alimentary bolus and then swallowing. It is a process with defined stages and patterns of movement that adapt to changes derived from the environment or the individual. Here, we review the main characteristics of chewing, including aspects of the physiology and characteristics of the mechanics of mandibular movement. We highlight the latest advances reported and the new methodologies used for a chewing analysis, which has made it possible to collect more precise and reliable data. Thus, we will see how the new technologies have provided a better understanding of this function and its relation to aspects of an individual's general healt h such as nutrition or the appearance of neurodegenerative diseases. Also, in this review we emphasize the close relation that exists between chewing and a person's quality of life.

SUMMARY: The aim of this study was to survey oral exostoses in human populations that belonged to the same region encompassing five periods over 6000 years, to determine the prevalence and its changing trend over time. A total of 306 human jaws belonging to the modern Xi'an region and four archeological sites, Banpo (6700-5600 years BP), Shaolingyuan (3000 years BP), Shanren (2200 years BP) and Chang'an (1000-1300 years BP), were investigated. The degree of buccal exostosis (BE), torus mandibularis (TM) and torus palatinus (TP) and the TP shape were recorded. The prevalence of BE, TM, and TP in the five groups was 20.8 %-62.5 %, 17.5 %-71.5 %, and 31.7 %-74.2 %, respectively. The differences in the three types of exostoses among the five groups were all statistically significant, but only TM and TP showed a decreasing trend over time. A high and quite diverse prevalence of oral exostoses was found in the five groups of samples. Decreasing trends in relation to time for TM and TP were detected.
RESUMEN: El objetivo de este estudio fue sondear las exostosis orales en poblaciones humanas que pertenecían a la misma región abarcando cinco períodos durante 6000 años, para determinar la prevalencia y su tendencia cambiante a lo largo del tiempo. Un total de 306 mandíbulas humanas pertenecientes a la moderna región de Xi'an y cuatro sitios arqueológicos, Banpo (6700-5600 años AP), Shaolingyuan (3000 años AP), Shanren (2200 años AP) y Chang'an (1000-1300 años AP) BP), fueron investigados. Se registró el grado de exostosis bucal (EO), torus mandibular (TM) y torus palatino (TP) y la forma de TP. La prevalencia de EO, TM y TP en los cinco grupos fue 20,8 % -62,5 %, 17,5 % -71,5 % y 31,7 % -74,2 %, respectivamente. Las diferencias en los tres tipos de exostosis entre los cinco grupos fueron todas estadísticamente significativas, pero solo TM y TP mostraron una tendencia decreciente con el tiempo. Se encontró una prevalencia alta y bastante diversa de exostosis oral en los cinco grupos de muestras. Se detectaron tendencias decrecientes en relación al tiempo para TM y TP.

SUMMARY: The aim of this study was to examine the localization of the landmarks in the maxillofacial region and their relations with each other and to evaluate them morphologically and clinically. Our study included 41 dry adult human skulls of unknown age and sex of Anatolian population. Statistical analysis of the data obtained in our study was performed with SPSS v.20.0 software (IBM Corp., Armonk, NY, USA). Statistical significance was accepted as P ? 0.05. Whereas the mean right supraorbital depth (SOD) value was significantly greater than the mean left SOD value (p 0.05). Correlation values in our study varied between -0.156 and 0.612. The highest correlation value was obtained in the positive direction between the orbital height (OH) and supraorbital foramen-infraorbital foramen (SOF-IOF) measurements (r = 0.612, p < 0.001). We believe that measurements of the orbit, SOF, and IOF and our data on their localizations, along with the relationships that we observed in our study will allow surgeons to avoid damaging the neurovascular bundles during surgical interventions and local anesthesia procedures in the frontal, periorbital, and maxillofacial regions.
RESUMEN: El objetivo de este estudio fue examinar la localización de los hitos en la región maxilofacial y sus relaciones entre sí y evaluarlos morfológica y clínicamente. Nuestro estudio incluyó 41 cráneos humanos adultos secos de edad y sexo desconocidos de la población de Anatolia. El análisis estadístico de los datos obtenidos en nuestro estudio se realizó con el software SPSS v.20.0 (IBM Corp., Armonk, NY, EE. UU.). La significación estadística se aceptó como P ? 0,05. Mientras que el valor medio de la profundidad supraorbitaria derecha (SOD) fue significativamente mayor que el valor medio de la SOD izquierda (p 0,05). Los valores de correlación en nuestro estudio variaron entre -0,156 y 0,612. El mayor valor de correlación se obtuvo en la dirección positiva entre las medidas de altura orbitaria (OH) y foramen supraorbitario-foramen infraorbitario (SOF-IOF) (r = 0,612, p <0,001). Creemos que las mediciones de la órbita, SOF e IOF y nuestros datos sobre sus localizaciones, junto con las relaciones que observamos en nuestro estudio, permitirán a los cirujanos evitar dañar los haces neurovasculares durante las intervenciones quirúrgicas y los procedimientos de anestesia local en la zona frontal, periorbitaria. y regiones maxilofaciales.
