“…However, in the Amsterdam population, DSC was observed more often in third molars that were impacted horizontally than in those angled mesially. However, horizontal impaction was the second most frequent angulation that was associated with the presence of DSC in the Manchester group; these findings were in line with previous reports and studies [ 18 , 19 ]. In the Bucharest population, the second most frequent third molar angulation associated with the presence of DSC was vertical impaction, which was not in line with the Manchester or Amsterdam results.…”

“…The literature describes a strong association between DSC development and mesially impacted third molars that are adjacent to mandibular second molars [ 18 ]. This strong association was also found in our study, and in the Manchester and Bucharest populations, third molars with mesial angulation were indeed associated with the greatest rate of DSC in the second molar.…”

Background: Distal surface caries (DSC) has been associated with partially erupted impacted third molars. The purpose of this study was to compare the rates of DSC between populations that had undergone different third molar management strategies. Methods: Radiographs that had been taken during routine examinations of 1012, 251 and 250 patients in Manchester, Bucharest and Amsterdam, respectively, were evaluated. The following parameters were assessed: the state of the distal surface in the second mandibular molar, loss of periodontal support, impaction type of the third molar, contact point localization, and patients’ genders, ages and their cumulative history of dental health. Results: The rate of DSC in the second mandibular molar was 63.9%, 19.9% and 26.0% in the Manchester, Bucharest and Amsterdam populations, respectively. A loss of lamina dura of ≥2 mm, increased percentages of decayed, missing or filled teeth and male gender were risk factors in all three populations. All assessed parameters apart from the site of the mandible reached statistical significance in the Manchester sample (p < 0.001). The DSC rate was cumulative with increasing age in the Manchester population, in which third molars were strategically retained. Conclusions: The UK population, treated according to strict guidelines that limit the removal of third molars, had a statistically significant higher DSC prevalence rate (p < 0.001) than the Romanian or Dutch populations. The active surgical management of mandibular third molars seems to have the potential to reduce the DSC rate in the adjacent second molar.

“…In 2019, McArdle and McDonald reported lower DMFT scores of patients with DSC than those of a surveyed population [30]. In the present study, the mean modified mDMFT-R was used, which was significantly higher in patients with rDSC in comparison to rDSCfree patients.…”

Background To determine the risk factors for the development of radiographic distal surface caries (rDSC) in patients who attend routine dental check-ups during an era of National Institute for Health Care Excellence third molar surgery guidelines. Methods Radiographs taken during routine dental examinations involving 1012 patients from Manchester, UK were accessed. Clinical parameters, oral health, patient demographics, and socioeconomic factors were assessed. Risk factors were identified by multivariate logistic regression analysis. Results The detected rate of rDSC was 63.9% and rDSC was distributed homogenously across all five socioeconomic groups (p = 0.425). Risk factors associated with rDSC (p < 0.001) were identified as partially erupted mesio-angularly impacted mandibular third molars, third molars with compromised molar to molar contact points, loss of lamina dura of ≥ 2 mm, male gender, increasing age, and a higher modified Decayed Missing Filled Tooth score. Conclusion rDSC was significantly associated with the angulation of third molars, the compromised contact position of the adjacent third molar, the periodontal status of the distal aspect of the second molar and the cumulative history of oral health in a population governed by specific third molar guidelines. An active approach to third molar surgical management could reduce rDSC and serve this population, irrespective of patients’ socioeconomic or deprivation status.

“…Impaction and semi-impaction account for the remaining quarter. [15][16][17] Dental procedures for tooth treatment or removal require a lot of time, which may cause some inconvenience to both doctors and patients. 18 The tooth autotransplantation, for instance, may be complicated by root resorption.…”

The Retromolar Space and Wisdom Teeth in Humans: Reasons for Surgical Tooth Extraction

Objective This article explores the problem of developing pathologies in the retromolar region. Findings can serve a framework for disease prevention and for the improvement of the quality of life of patients. The present study aims to justify the possibility of utilizing morphometric methods to foresee problems in the eruption of third molars. Materials and Methods A comprehensive morphometric study of the lower jaw and facial skeleton involves 100 skulls of Homo sapiens to identify the anatomical causes of problems with wisdom teeth eruption. All said skulls are divided in two groups: I: skulls with intact dentition; II: skulls with impacted third molars. Results This work allows detecting abnormalities in the eruption of the third molar with high probability of success. The abnormalities in point are considered not only those associated with the generally accepted parameters but also those that occur in the leptoprosopic face cases. Conclusions Face type and the structural features of the facial skeleton play a significant role in the abnormal eruption of the lower third molar.
