Predicción del grado de dificultad para la extracción de terceros molares mandibulares en el centro imagenológico de la Universidad Católca de Cuenca sede Azogues

Abstract

The objective of this research was to determine the degree of difficulty with the highest prevalence for the extraction of mandibular third molars using the Kharma scale in panoramic radiographs from patients attending the dental specialty center of the Universidad Católica de Cuenca Sede-Azogues, in a time lapse between January 2018 to January 2020. The methods and materials were descriptive, observational, retrospective cross-sectional study, where 616 retained mandibular third molars were analyzed, included and impacted in 379 digital panoramic radiographs. Results show the degree of difficulty with the highest prevalence was slightly difficult with a percentage of 55.8% (344), the female gender showed a higher prevalence of retained, impacted and included third molars, reaching 59% (364), 59.7% (368) of all cases were between the ages of 17 to 20 years, according to the location of the third molar it was evidenced that 51% (314) were on the left side, the mesioangular position was observed in 57.3% (353) of all in the cases, according to the depth, level A corresponded to 55% (336), according to the relationship with the ascending branch, 81% (501) of all cases was class II and according to the root form 57% (350) it was convergent. CONCLUSION: According to the Kharma scale, the third molar extraction difficulty index established that the vast majority of all cases presented a slightly difficult degree of difficulty.
