“…This higher incidence of impaction in females can be as a consequence of the stopping growth of both jaws before the third molar erupts, unlike in men, where the jawbones continue to grow even during the molar eruption, thus creating the space required to align the tooth on the arch. However, there are also many authors who believe that there is no gender predilection regarding these impactions (6,7). As a result of this present study, we conclude that impactions were more frequent on the inferior arch compared to the upper arch, which is in agreement with a similar study that showed an increased incidence of impacted wisdom molar in lower arch compared to the upper one (8).…”

Objective: The aim of this study is to determine the incidence of inclusion of lower and upper third molar in the population of Mures county.Materials and Methods: For this study, we examined the orthopantomograms (OPGs) of 243 patients (including 138 women and 105 men , aged 19-57 years old) who had impacted third molars and who presented to three Orthodontic Clinics in Tîrgu Mureș between 2015-2017. All impacted third molars were taken into consideration but which at the same time presented fully developed roots. We excluded from the study patients with pathological condition or craniofacial syndromes such as cleidocranial dysostosis and Down syndrome.Results: In both women and men, the most common cases were of one impacted molar (61,72%), then two (27,16%) and three (11,12%) impacted molars. Based on the evaluation of all radiographs, 363 impacted teeth were observed, with a higher proportion in women (54,27%) compared to men (45,73%). With regard to the location of the impacted teeth in the mandible or the maxilla, in both female and male patients, the incidence of mandibular impactions was higher (62,25%) than in the maxilla (37,75%). Regarding the link between the position on the arch (right and left side) and the localization of the impacted teeth, in female patients we can assert that while the mandible had the largest number of impacted teeth on the right side ( 69,35%), the impacted teeth in the maxilla were more numerous on the left side (60,27%) (p=0,00004). In male patients, regardless of whether the impactions were in the mandible or in the maxilla, they were more frequent on the right side ( 70,58% in mandible and 76,56% in maxilla) than on the left one.Conclusions 1. The incidence of impacted wisdom teeth is higher in females compared to males. 2. Impacted wisdom teeth are more common on lower arch than on upper arch. 3. In female patients, the prevalence of impaction is higher on the right side in the mandible and on the left side in the maxilla 4. In male patients, the prevalence of impaction on the right side is higher in both mandible and maxilla

“…19 Kumar et al too did not find predilection towards any of the genders in third molar impaction cases in Eritrean population. 20 However, there are studies with findings showing impacted third molars are more common in one of the two sexes. Ayaz and Rehman while studying the third molar impaction in the population of Peshawar, Pakistan found out that males were affected more than females.…”

Background: Few studies have been reported so far on the frequency of lower third molar impactions in patients with different morphological characteristics. Our aim in this study was to find out the frequency of impacted lower third molars in orthodontic patients with different antegonial notch depths. Material and Methods: This cross-sectional research was conducted at Orthodontics Department of Dental Section, Faisalabad Medical University, Faisalabad, and de’Montmorency College of Dentistry, Lahore, Pakistan from June 2017 to June 2019. A total of 60 orthopantomograms (OPGs) of patients with impacted lower third molars were included. The depth of antegonial notch was calculated on all the selected OPGs by measuring distance between the deepest area of the notch cavity and the tangent on the inferior border of the mandible. The patients with depth of antegonial notch of 1 mm or less were labeled as having shallow antegonial notch, while those with 3 mm or more were considered as having deep antegonial notch. Percentages and mean + SD were calculated for different variables. Depth of antegonial notching was compared between genders using ANOVA with P-value <0.5 considered as significant. Results: Of 60 orthodontic patients, there was an equal number of male and female patients (n=30). The average age of the patients was 25.5±4 years. Overall frequency of impactions was similar in both the genders and frequency of impacted lower third molars was found to be greater in patients with deeper antegonial notches. Conclusion: Mandibular third molar impactions were most frequent in orthodontic patients with deep antegonial notches

“…1 Peterson later characterized impacted teeth as tooth that neglects to eject into the arch in the normal time. 2 Agarwal characterized affected tooth as a 'tooth which is kept from eruption on account of anatomical boundary in the eruption pathway. 3 Frequently impaction has been accounted for the mandibular and maxillary third molar, trailed by maxillary canines and the mandibular pre-molars.…”

Objectives: To evaluate the severity of post-operative pain after surgical extraction of impacted mandibular third molar using two different techniques i.e. comma incision and standard Wards incision. Study Design: Interventional study. Setting: Department of Oral surgery, Isra Dental College Hospital. Period: From January 2016 to June 2016. Material & Methods: A sample of 50 patients of impacted third molar was selected by non-probability purposive sampling for tooth extraction either by conventional technique or by coma shaped incision. Post-operative amount of pain was measured on 1st, 3rd and 7th day respectively. Results: Mean ± SD age in group A and B was noted as 28.5 ± 4.32 and 27.2 ± 4.39 years respectively. Male and female in groups A and B were noted as 16 (64%) and 9 (36%), & 14 (56%) and 11 (44%) respectively. Right and left lower mandibular teeth extraction in groups A and B were noted 11 and 14, & 10 and 15 respectively. Pain was measured after extraction at day 1, day 3 and day 7. Conclusion: The Coma incision was preferable over the conventional method- the standard Ward`s incision because of lesser degree of post-operative pain.
