“…In the present study, the incidence of mandibular third molar impaction in females was higher than that in males (3:2), which was in agreement with the results of previous studies [1,3,20,21]. Higher frequency in females can be due to differences in growth patterns of males and females.…”

To assess the patterns of mandibular third molar impaction in an Iranian subpopulation. Material and Methods: This retrospective descriptive study evaluated 1000 panoramic radiographs retrieved from the archives of a private radiology clinic in Kermanshah city, Iran. Depth of impaction, position of impacted mandibular third molar relative to the mandibular ramus according to Pell and Gregory's classification and angle of impacted tooth according to Winter's classification were determined. Data were analyzed using the Chi-square and Wilcoxon tests. Results: Of 1000 radiographs, 230 (23%) showed an impaction of at least one mandibular third molar. Mandibular third molar impaction was more common in females (60%). Mesioangular (35.9%) and vertical (34.8%) impactions were the most common angles of impaction in the right and left sides, respectively. Level C (40.3%) and Class I (63.7%) were the most common types of impaction in terms of depth of impaction and position relative to ramus, respectively. No significant difference was observed between the right and left sides of the mandible in terms of patterns of mandibular third molar impaction (p>0.05). Conclusion: Mandibular third molar impaction was relatively common in the studied population. The mesioangular, level C and Class I impaction patterns were the most frequent.

“…The factors that influence the surgical complexity of the extraction of impacted mandibular third molars can be divided into three main groups: related to tooth shape and position, operative variables (surgical technique and operator experience) [10][11][12] and demographic variables (age, sex, ethnicity) [10][11][12][13] .…”

“…Due to the efficacy of anesthesia, hemostasis and transoperative bone perfusion 20 articaine was the most prevalent anesthetic base for inferior alveolar nerve block and lingual and buccal nerves. It is established that -in erupted teeth -the surgical technique to be used is the closed or simple technique, which has as characteristics the use of elevators and forceps to extract the dental element 10,11,18,19 .…”

Introduction: establish an association between the radiographic classification and the surgical technique related to the lower third molars. Materials and method: a retrospective study was carried out, with the descriptive analysis of the data. The sample consisted of 100 patients (n = 100) from the spontaneous demand who sought out the Dental Clinic of UFC (Ceará's Federal University) -Campus Sobral, between december 2017 to july 2018, and who followed the inclusion criteria: patient with panoramic radiography, free of active periodontal disease and tooth with at least two thirds of root formation; and as exclusion criteria: patients with associated bone pathologies, teeth with less than two thirds of root formation and patients who did not wish to participate in the study. Results: patients included in the study were from 18 to 25 years of age, most of them male, with complaints of pain. Using the radiographic classification of Pell & Gregory, the most found positions were 1A (35%), 2B (28%) and 2A (17%). The most prevalent surgical techniques were the open ones. Could be done the extraction by closed surgical technique (forceps or lever) (n = 27), with flap preparation plus osteotomy (OST) (n = 25) and flap plus osteotomy plus odontostomy (ODS) (n = 48). Conclusion: teeth with radiographic classification, grade of inclusion and different preoperative plans had the same protocol (flap + OST + ODS) in the surgical act. It is evident that radiographic classification stills an effective method to aid in operative planning, but it can be complemented by other diagnostic standards, such as a specific classification of the root anatomy.

“…The most common oral surgery is extraction or surgical removal of the third molar [1, 2]. The important consideration that is necessary in the mandibular third molar removal procedure is avoidance of inferior alveolar nerve injury.…”

Background The aim of this study was to determine the distance between the impacted mandibular third molar (IMTM) and the inferior alveolar canal (IAC) at different reference points through panoramic radiographs and cone beam computed tomography (CBCT). Methods A total of 45 male and 45 female patients with bilateral IMTM at a mean age of 27 years were recruited for this study. With the aid of panaromic radiographs and CBCT, the mandible width, the buccal bone width, IAC width, the lingual bone width, IAC height, the alveolar bone height, and the distance from the lowest part of the IMTM to the superior border of the canal were measured. Statistical analysis was done with independent samples t -test and Mann-Whitney U test for finding the difference between genders. Paired t -test and Wilcoxon signed-rank test were used for comparing both sides at P value = 0.05. Results The mandible width, IAC width, and IAC height were different between male and female patients. The IMTM roots displayed intimate contact with the IAC in 96.67% of the cases. The location of the IAC was mostly lingual in both genders. The diameter of the IAC was significant larger in men compared to in the women in terms of width and height. Conclusions This study is useful for the dental surgeon to avoid or prevent postoperative numbness or pain, because the awareness of the common location of the IAC and its approximation with the IMTM roots could allow a more cautious and precise approach during IMTM intervention.
