Prevalencia de periodontitis apical en dientes del maxilar superior presentes en CBCT tomadas en la universidad Santo Tomas durante los años 2016 y 2017

Abstract

The Apical Periodontitis is a condition multifactorial originated principally from a necrotic pulp infected or for the failure of a treatment endodontic. In most cases it is of asymptomatic course and when his detection is early the forecast is favorable. Multiple investigations worldwide recount the prevalence of the Apical Periodontitis, which might be in 30 to 50 % of the individuals. The presence of treatments endodontics, trauma dentoalveolar, frontal inadequate restorations and cavities has been a partner to these percentages; nevertheless in Colombia the literature on the topic is scanty. The Tomography computarized Cone Beam (CBCT) projects a three-dimensional image of the teeth and his adjacent fabrics, minimizing the overlapping structure and allowing a more precise diagnosis. During the capture it uses a bundle of X-rays in the shape of centred cone which generates a rotation of 180 ° to 360 ° about the head of the patient and later he will acquire a volume in 3D of maxillary both or of a specific zone of the mouth. Objective: Determine the prevalence of Apical Periodontitis in teeth of the upper jaw found in tomographies of conical bundle taken in the center of Diagnostic Images of the Saint Thomas University during the year 2016 and 2017. Type of study: Observacional descriptively of transverse court. Materials and methods: there will be evaluated 60 CBCT of the upper jaw taken in the Center of Diagnostic Images of the Saint Thomas University during the year 2016 and 2017. Results: There were interpreted 60 tomographies, the total of examined teeth was of 692. 63,3 % (38) of the tomografías concerned to women. The average age was 46,5 years (range from 20 to 82 years. The tooth with the highest prevalence of Apical Periodontitis was 26 and 24 with a proportion of 34,9 % and 32,6 % respectively. Conclusion: A very low percentage of the studied population was possessing the totality of the present teeth in the upper jaw. The tooth with the highest Apical Periodontitis was 26. The prevalence of Apical Periodontitis was 21,6 %, in case of teeth with endodontics treatment 12,4 % and teeth without endodontics treatment 9,2 %
