Prevalencia y caracterización de complejidad según la escala de PEDERSEN del tercer molar inferior en pacientes de clínica-integral III.

Abstract

Introduction: Pedersen has developed a difficulty index for impacted mandibular third molars, considering aspects such as angulations, depth and relationship with the mandibular ramus. Objective: Determine the prevalence and characterization of complexity in the lower third molar using the PEDERSEN scale in patients of comprehensive dentistry clinic III – UCSG. Materials and Methods: Observational descriptive study. Universe of 161 folders excluding 56 folders that did not meet the research criteria, leaving a sample of 105 folders with panoramic x-rays. The behavior of the variables of interest of all patients treated at the Comprehensive Clinic III of the Catholic University of Santiago de Guayaquil was recorded Results: The prevalence of surgical complexity according to the Pedersen index was the least difficult with the highest proportion in males with 53.1% and in females with 38.4% for both molars (3.8 and 4.8).Conclusion: The highest frequency of impaction of the mandibular third molar occurred in the female sex in the age range of 40 years or more, the mesioangular position is the most prevalent in both genders as well as level A depth and class I available space. and most cases are considered low difficulty according to the Pedersen scale. Males presented a greater proportion of low difficulty cases compared to females, with a significant association between sex and the degree of difficulty.
