Hallazgos incidentales en ortopantomografías maxilomandibulares de pacientes adultos jóvenes / Incidental findings on panoramic radiographs of the maxilla and mandible of young adult patients

Introducción: la valoración radiográfica rutinaria en la práctica odontológicaes esencial para un adecuado diagnóstico y plan de tratamiento. Laortopantomografía o radiografía panorámica es una técnica simple, rápida, de bajo costo y a una baja dosis de radiación. Objetivos: Caracterizarlos hallazgos incidentales más comunes en radiografías panorámicas de pacientes adultos jóvenes de una clínica dental universitaria. Materialy métodos: Se realizó un estudio descriptivo, retrospectivo, de cortetransversal de radiografías panorámicas digitales, tomadas e interpretadas de manera ciega, explorando alteraciones óseas y anomalías dentales. Se realizó la caracterización de su presentación por género de los participantes. Para el análisis de datos se utilizaron pruebas no paramétricas (la prueba χ2, exacta de Fisher y binomial). Resultados: Se tomaron 98 radiografías del mismo número de pacientes, con edad promedio de 19.45 años, predominando las mujeres (69/70.40 por ciento), solteros (94/95.91 por ciento) y de zona urbana (77/78.57 por ciento). Existieron 387 alteraciones, 268 (69.25 por ciento) enmujeres, y 119 (30.74 por ciento) en hombres, con un promedio de 3.88 y 4.10 alteraciones por paciente, respectivamente. La distribución mostró en total 122 (31.52 por ciento) lesiones a nivel de senos maxilares, 124 (32.04 por ciento) en fosasnasales, 16 (4.13 por ciento) lesiones radiolúcidas u opacas, y 125 (32.29 por ciento) anomalías asociadas a retención dental. La comparación de acuerdo al género mostró diferencia (p ≤ 0.001) en la frecuencia de alteraciones, en todos los casos determinada por las mujeres, para cada sitio y tipo de lesión presentada. Conclusiones: El valor de la radiografía panorámica para detectar anomalías de estructuras orofaciales demostró en este estudio su utilidad en la práctica asistencial desde una perspectiva epidemiológica.

Background: doutine dental X-Ray assessment in dental practice isessential for proper diagnosis and treatment. Orthopantomographyor panoramic radiography is a quick, simple, low-cost, and low-doseradiation technique. Objective: To describe the most common incidentalfi ndings on the panoramic radiographs of young adult patients ata university dental clinic. Material and methods: A descriptive,retrospective, cross-sectional study was carried out, in which digitalpanoramic radiographs were taken and interpreted blindly to examinebone disorders, and dental anomalies, and the prevalence of theseaccording to the gender of the participants. Nonparametric statistics(Chi-square χ2, Fisher’s exact, and binomial tests) were used for dataanalysis. Results: 98 radiographs were taken of the same number ofpatients with a mean age of 19.45 years, most of whom were women(69/70.40%), single (94/95.91%), and from urban areas (77/78.57%). 387alterations were found, 268 (69.25%) in women and 119 (30.74%) in men,with an average of 3.88 and 4.10 alterations per patient, respectively. Thedistribution presented a total of 122 (31.52 %) lesions in the maxillarysinus, 124 (32.04 %) in the nostrils, 16 (4.13 %) radiolucent or opaquelesions, and 125 (32.29%) anomalies associated with tooth retention. Acomparison by sex revealed a diff erence (p < 0.001) in the frequency ofalterations, which was greater in women for all sites and types of lesion.Conclusions: The study showed the usefulness of panoramic radiographyin clinical practice to detect anomalies of the orofacial structure from anepidemiological perspective.

Dental Pathologies in the Three Kingdoms Period Population from Imdang Site, Gyeongsan, Korea / 체질인류학회지

Dental pathology has the potential to provide insight into the interpretation of the health and life style of past population. In particular, dental pathologies are strongly correlated to subsistence pattern, diet habits and food-preparation techniques. For this reason, my studies have focused on analyses of dental diseases (e.g., caries, abscesses, ante-mortem tooth loss, enamel hypoplasia, dental attrition, and periodontal diseases). The purpose of this study is to investigate the prevalence of dental pathologies of the Imdang population dating to between A.D. 3rd and A.D. 7th centuries (Three Kingdoms Period). In this study, through a macroscopic observation of dental remains from 138 individuals of the Imdang site, the prevalence of caries, abscess and ante-mortem tooth loss was examined. The association between sex, age and the frequencies of pathology was analyzed by the Chi-square tests. The results showed that the frequency of dental pathologies was consistently low level in Imdang population. Caries prevalence in the Imdang population was higher in females (6.15%) that in males (4.89). Among dental pathologies, abscess prevalence (0.7%) was lowest in Imdang population. Meanwhile, AMTL prevalence was 10.81% in males and 3.8% in females. There is a statistically significant difference between the anterior teeth of males and females (p<0.05). This study revealed that the rate of dental caries, abscess and AMTL in the Three Kingdoms Period population was relatively low level. This study is the first report of the patterns of dental pathologies in the Three Kingdoms Period population. It is necessary to investigate more number of pathologic markers that needed for deeper understanding of the multi-faceted nature of dental pathologies of ancient populations.
