A systematic review of second molar distal surface caries incidence in the context of third molar absence and emergence

Objective: The aim of the study was to evaluate the frequency of distal caries in the second molar influenced by the angulation of the third molar adjacent on panoramic radiographs in a clinical dental radiology. Material and Methods: A descriptive and quantitative study that examined 750 panoramic radiographs, of this total, 120 were in accordance with the inclusion criteria of the study was conducted. Results: 157 seconds and third molars analyzed the prevalence of caries in the distal of the second molar was 25.5%. The most prevalent angle position of the third molar was 57.3% with the vertical, but the position with the highest percentage of decayed molar second distal mesioangular was 50% of the cases. The elements listed, males obtained 40% of second molar distal caries versus 17% for females. People aged 35 or older had the highest incidence with 50% distal caries while other bands obtained 16.21% in the group 18-24 years, and 23.52% in 25-34 years. Conclusion: It was possible to establish a sliding scale on the indication for prophylactic removal of mandibular third molar according to the angulation of Winter: horizontal, mesioangular, vertical and distoangular. One can also see a greater relevance to the indication of prophylactic removal of male individuals aged over 35 years.

Third Molar Eruption

A retrospective study, using panoramic radiographs, was conducted on 152 Taiwanese (72 males and 80 females) to investigate mandibular third molar eruption and impaction. The following measurements were made: inclinations and mesiodistal crown widths of the mandibular molars, vertical and horizontal spaces between the distal surface of the second molar and the anterior surface of the ramus, lengths and widths of the mandibular ramus and body, the ramus inclination, the mandibular plane angle, and the mandibular gonial angle. Differences between non-impaction and impaction groups were studied, and the variables were analyzed with multivariate discriminatory analysis. Significant differences between the two groups were found; variables describing spaces between the anterior of the ramus and the distal of the mandibular second molar and tooth size appeared to be the primary contributors to the differences observed.
