Morphological evaluation of dental diseases in Parion chamber tomb (OM 5) Roman people / Evaluación morfológica de enfermedades dentales en la tumba de la cámara de Parion (OM 5) del pueblo romano

SUMMARY: Most of the dental diseases occur due to tooth or jaw morphology or nutritional habits. Anatomical differences in the teeth and jaws of men and women can cause different dental diseases between the sexes. In this study, 33 skeletons obtained from the excavation of the ancient city of Parion, which are dated to the late Roman period, were examined. Dental diseases and possible causes were investigated on a total of 33 skeletons. In the evaluations, it was evaluated that some diseases were caused by the difference between the sexes, while some were classified as nutritional diseases. The rates of tooth decay are different between men and women with Parion. It has been determined that the most important reason for this is the different morphological structure of the jaws and teeth, but the nutritional differences also cause this. Other dental and jaw diseases were also evaluated in the Parion population.

RESUMEN: La mayoría de las enfermedades dentales se deben a la morfología de los dientes o la mandíbula o a los hábitos nutricionales. Las diferencias anatómicas en los dientes y las mandíbulas de hombres y mujeres pueden causar diferentes enfermedades dentales entre los sexos. En este estudio, se examinaron 33 esqueletos obtenidos de la excavación de la antigua ciudad de Parion, que datan del período romano tardío. Se investigaron las enfermedades dentales y las posibles causas en un total de 33 esqueletos. En las evaluaciones, se determinó que algunas enfermedades fueron causadas por la diferencia entre los sexos, mientras que otras fueron clasificadas como enfermedades nutricionales. Además se encontraron diferentes estimaciones de caries entre hombres y mujeres. Se analizó que la razón más importante de esto es la diferencia de la estructura morfológica de los maxilares y los dientes, sin embargo las diferencias nutricionales también es un factor que se debe considerar. Se evaluaron además, otras enfermedades dentales y de la mandíbula en la población de Parion.

Influence of photobiomodulation therapy on root development of rat molars with open apex and pulp necrosis

Abstract This study aimed to evaluate the role of photobiomodulation (PBM) in apexification and apexogenesis of necrotic rat molars with an open apex. Rat molars were exposed to the oral environment for 3 weeks. Canals were rinsed with 2.5% NaOCl and 17% EDTA, filled with antibiotic paste and sealed. After 7 days, canals were rinsed and divided into six groups (n=6): mineral trioxide aggregate (MTA); blood clot (BC); human dental pulp stem cells (hDPSC); MTA+PBM; BC+PBM; and hDPSC+PBM. In hDPSC groups, a 1% agarose gel scaffold was used. Two groups were not exposed: healthy tooth+PBM (n = 6), healthy tooth (n = 3); and one was exposed throughout the experiment: necrotic tooth (n = 3). In PBM groups, irradiation was performed with aluminum gallium indium phosphide (InGaAlP) diode laser for 30 days within 24-h intervals. After that, the specimens were processed for histological and immunohistochemical analyses. Necrotic tooth showed greater neutrophil infiltrate (p < 0.05). Necrotic tooth, healthy tooth, and healthy tooth+PBM groups showed absence of a thin layer of fibrous condensation in the periapical area. All the other groups stimulated the formation of a thicker layer of fibers (p < 0.05). All groups formed more mineralized tissue than necrotic tooth (p < 0.05). PBM associated with MTA, BC, or hDPSC formed more mineralized tissue (p < 0.05). MTA+PBM induced apexification (p < 0.05). Rabbit polyclonal anti-bone sialoprotein (BSP) antibody confirmed the histological findings of mineralized tissue formation, and hDPSC groups exhibited higher percentage of BSP-positive cells. It can be concluded that PBM improved apexification and favored apexogenesis in necrotic rat molars with an open apex.

Frecuencia de Lesiones y Condiciones Orales en Pacientes Mayores de 18 Años en una Clínica de Atención Primaria en México / Frequency of Lesions and Oral Conditions in Patients Older than 18 Years in a Primary Care Clinic in Mexico

RESUMEN: La patología oral es el área de la odontología que se especializa en el diagnóstico y tratamiento de enfermedades orales. Se realizó un estudio transversal, en el cual fueron incluidos pacientes mayores de 18 años que acudieron a una clínica de atención primaria del departamento de estomatología de la universidad Autónoma de Ciudad Juárez, en México y a los cuales independientemente del motivo de consulta se les realizo historia clínica y exploración intraoral detallada. Fueron examinados 650 pacientes (424 mujeres y 226 hombres) con un rango de edad de 18 a 89 años (media=42.27). Las lesiones más frecuentes fueron la queratosis friccional (30,46 %) e hiperplasia fibrosa (6,92 %), la melanosis fisiológica (42,92 %) y los gránulos de Fordyce (36,46 %) fueron las condiciones más identificadas. En las lesiones de la mucosa oral que identificamos estuvo presente el factor traumático de manera crónica, es importante que el odontólogo este familiarizado con las lesiones más frecuentes, con su etiología, características clínicas y tratamiento de cada una de ellas.

ABSTRACT: Oral pathology it's the branch of medicine that focuses on the diagnosis and treatment of oral diseases. A cross-sectional study was carried out in which patients older than 18 years was included, that were attended in the primary care clinic at the stomatology department of the Autonomous University of Ciudad Juárez, in Mexico, and regardless of the reason for consultation the clinical history and intraoral examination was done We examined 650 patients (424 women and 226 men) with an age range of 18 to 89 years (mean=42.27). The most frequent oral lesion was the frictional keratosis (30.46 %), fibrous hyperplasia (6.92 %), physiological melanosis (42.92 %), and fordyce granules (36.46 %). In the oral mucosal lesions identified was present a chronic traumatic factor, it is important that the dental staff knows about the most frequent injuries, their etiology, clinical characteristics and treatment of each one.

Floor of the nose mucosa lysis and labial abscess caused by a bee sting

Hymenoptera order includes bees, which have a stinging apparatus at the tail capable of delivering venom to the affected tissues. Myocardial infarction, acute renal failure, Necrotizing fasciitis, fatal infection and hemifacial asymmetry, are some of the unusual reactions reported following hymenoptera stings. This paper reports a case of bee sting in the right floor of the nose that mimicked an odontogenic infection affecting the upper lip, canine space and nasal cavity such as in cases of infection secondary to pulpal or periodontal pathology of the anterior teeth. After a thorough clinical and radiographic examination, odontogenic infection was discarded and the diagnosis of floor of the nose mucosal lysis and lip abscess secondary to a bee sting was made. This case was successfully managed with adequate incision, drainage and antibiotics without any further complication. There are several reports of unusual reactions following hymenoptera stings. However, just a few of them referred to infections of local reactions and none of them related to the anatomic location affected in the patient of the present case. Early diagnosis and treatment prevented infection dissemination and the likelihood of tissue necrosis as in previously reported cases of Necrotizing fasciitis.

A ordem das himenópteras inclui abelhas, que possuem um ferrão na cauda capaz de de injetar veneno nos tecidos afetados. Fasciite necrosante, infecção fatal e assimetria hemifacial são algumas das reações incomuns relatadas após picada de himenópteras. Este estudo relata um caso de picada de abelha no assoalho da narina direita que simulou uma infecção odontogênica atingindo o lábio superior, o espaço canino e a cavidade nasal, como observado nos casos de infecção secundária após patologia pulpar ou periodontal dos dentes anteriores. Após completo exame clínico e radiográfico, foi descartada a hipótese de infecção odontogênica e foi estabelecido o diagnóstico de lise da mucosa do assoalho da narina e abscesso do lábio, após picada de abelha. Este caso foi tratado com sucesso com adequada incisão, drenagem e administração de antibióticos, sem outras complicações. Há vários relatos de reações incomuns resultantes de picada de himenópteras, porém poucos são relativos a infecções locais e nenhum se refere à localização anatômica afetada no paciente do caso aqui relatado. Diagnóstico e tratamento precoces preveniram a disseminação da infecção e a possibilidade de necrose tecidual, como já relatado em casos de fasciite necrosante.
