“…Quadrant III presented greater complications and longer surgical time. Villafuerte (25) observed that the size of the follicular sac is 0.25 mm, in such a way that, the smaller this follicle, the more complicated the extraction will be due to the risk of ankylosis, which entails a higher frequency of complications. Thus, in this study, 6 of the complications occurred in teeth that had a follicular size of 0.…”

“…For the analysis of root morphology, a radiographic inspection was also carried out in which the presence of fusions, separations, or multiplicity of the roots of the retained lower third molar was observed (14,24). For the size of the follicular sac, the radiolucent space on the crown of the tooth was measured with a millimeter ruler (14,25). Likewise, the letters D and I were placed on the vegetable paper to determine if the third molar was located on the right (D) or left (I) (Figure 3).…”

Background: Third molar eruption occurs in a very limited space. Several difficulty scales have been used to determine the complexity when extracting retained molars, which are key for surgical planning and prediction. A scale including indicators such as quality of mucosa and bone, as well as shape and number of roots is introduced. Purpose: Evaluate the difficulty in extracting retained lower third molars, using the scale proposed by Romero-Ruiz, and thus estimate the presence of intraoperative complications and surgical time. Methods: An observational descriptive cross-sectional study was carried out, with a sample of 100 extractions of retained lower third molars in patients between 16 and 40 years of age. The following variables were evaluated: spatial relationship, depth, relationship with mandible ramus/space, integrity of bone and mucosa, roots, dental follicle, and surgical time. The data were summarized in absolute frequency tables and analyzed with Pearson's Chi2 test (p < 0.05). Results: 71 % of third molars were classified as “difficult” on the scale. There were significant differences in terms of surgical time-age (p = 0.002), presence of complications-location of the third molar (p = 0.015), presence of complications-follicle size (p = 0.022), difficulty-sex (p = 0.011 ), difficulty-age (p = 0.068). Conclusions: This scale can be used to plan extraction treatments for retained lower third molars to reduce surgical times and anticipate complications.
