Determinación del pronóstico en pacientes que presentan caninos maxilares impactados de la Facultad de Odontología de la Universidad de Antioquia / Determination of the prognosis in patients who presenting impacted maxillary canines in the Faculty of Dentistry of the University of Antioquia

Introducción: la impactación de los caninos maxilares es una alteración poco frecuente en la vía de erupción quedebe ser diagnosticada y pronosticada a tiempo. Se hizo un análisis descriptivo en una muestra de dieciocho pacientes de la Facultad de Odontología de la Universidad de Antioquia en Medellín, Colombia, recolectando información epidemiológica y aplicando análisis radiográficos de impactación de caninos maxilares para verificar su asociación predictiva. Métodos: se hizo valoración clínica de los pacientes con impactación de caninos maxilares y se tomaron, escanearon y trazaron digitalmente unaradiografía panorámica y tres periapicales de cada diente objeto de estudio, en las cuales se aplicaron los análisis de Lindauer, Warford, Power y Short, y Clark. Resultados y conclusiones: se encontró prevalencia de impactación canina del 2,9%, mayoren pacientes de sexo femenino, en el primer cuadrante, en ubicación vestibular y con malposición asociada del incisivo lateral adyacente. Adicionalmente, se observó una fuerte concordancia y asociación positiva entre el análisis de Warford, y el de Powery Short, mas no de estos con el análisis de Lindauer. Se concluye que para predecir el pronóstico de caninos maxilares impactados es válido realizar tanto el análisis angular como el sectorial en radiografías panorámicas.

Introduction: maxillary canine impaction is a rare alteration in the eruption pathway that must be diagnosed andprognosticated on time. A descriptive analysis was performed in a sample of 18 patients of the School of Dentistry of the University of Antioquia in Medellín, Colombia, in order to collect epidemiological information and apply some radiographic maxillary canineimpaction analysis to verify its predictive association. Methods: a clinical evaluation of the patients with canine maxillary impactionwas carried out and a panoramic radiographs and three periapical of each studied tooth were taken, scanned, and digitally traced, then Lindauer, Warford, Power and Short, and Clark analysis were performed. Results and conclusions: a prevalence of canineimpaction of 2,9% was found, significantly higher in females, in the first quadrant, in a labial location and with an associated adjacent lateral incisor malposition. Additionally, a high concordance and a positive association between Warford and Power andShort analysis was noted, but not with the Lindauer analysis. It was concluded that to predict the prognosis of canine maxillary impaction it is valid to apply the angular as well as the sector analysis in panoramic radiographs.

Reverse smokers's and changes in oral mucosa. Department of Sucre, Colombia.

OBJECTIVES: This work is intended to establish the prevalence of reverse smokers at the villages of Hato Nuevo, San Francisco and Cayo de Palma, Department of Sucre, Colombia, characterizing their socio-culture conditions, clinical and histological changes in the oral mucosa. DESIGN OF STUDY: A descriptive study was done through a home to home inquiry to select the people with inclusion criteria for a posterior clinical test and a biopsy of the affected oral mucosa. RESULTS AND CONCLUSIONS: Reverse smokers's prevalence was from the 15%, mainly women (p<0.001) with an age average of 59.3 years. The lesions were classified clinically in mild, moderate and severe changes. Tongue moderate lesions presented the higher frequency (80%), followed by severe lesions on palate (74%). Oral cancer prevalence was 10.8% in the San Francisco village and 18.2% in Cayo de Palma village, no new cases were reported in Hato Nuevo village. This was the highest prevalence reported in comparison with other studies with similar population. The clinical and histological findings agree with the reported in literature, no relation was found between the degree of clinical severity and the dysplasia itself. Cases of oral submucous fibrosis-like lesions were found, which had never been reported in Latin America. Further studies are required in order to decrease the morbidity for this habit and to identify other related risk factors.
