“…The mean patient age in our study is high, probably because of an increasing incidence of distal caries in elderly patients, which is consistent with the findings of previous studies [18,19]. Because it is directly related to increasing age, Toedtling et al [20] argue that dental caries is significantly linked to the length of time a wisdom tooth is in a partially erupted state; consequently, these patients are older. A previous study revealed that the contact point between M2 and M3 had significant effects on caries formation [17].…”

The objective of this study was to verify whether caries and periodontal diseases, when present on the distal surface of the second molars (M2s), are associated with the eruption of the third molars (M3s). In this split-mouth study, we evaluated 70 elderly patients with unilateral maxillary or mandibular M3s who presented to the outpatient clinics of two hospitals. Patients underwent comprehensive oral examinations and radiographical measurements, and we assessed the outcomes of periodontal disease and caries. Periodontal measurements included plaque index, bleeding on probing, and periodontal probing pocket depth (PD). Moreover, caries were assessed through visual-tactile examination and radiography. We performed the χ test to determine factors associated with M3 and non-M3 outcomes. Eighty-one unilateral erupted M3s were observed in the study patients. Both the distobuccal region (p<0.0001) and the distolingual region (p=0.006) had a higher PD on the nonextraction side than the extraction side, and the caries rate was significantly higher on the nonextraction side than on the extraction side (p <0.0001 on M2 with caries and p=0.003 on M2 with distal caries). M3 eruption, at the same or different occlusal plane levels of M2, is a risk factor for periodontal diseases and caries in M2s in elderly patients. M3s may continue to negatively impact dental health well into later life.

“…The findings of this study showed that there was no statistically significant association between gender and number of impacted mandibular third molar as well as whether the mandibular third molar was located on the right or left quadrant, similar to reports of a previous study [4] and differs from other studies [9,17] that observed association between gender and number of impacted mandibular third molar Studies [24,25] have reported distal caries on the adjacent second molar associated with impacted third molar.

tion system was adapted to classify occupation into five (5) socioeconomic groups: Professionals and managerial officers and retirees of this type (e.g. doctors, lawyers), skilled workers (e.g. teachers, nurses), semi-skilled workers (e.g. artisans), unskilled workers (e.g. traders) and dependants (students and other unemployed individuals).Inclusion criteria were all consenting patients with at least one impacted mandibular third indicated for extraction. Informed consent was obtained from all the participants. Ethical approval was obtained from the Ethics and Research Committee of the College of Medical Sciences, University of Benin before commencement of the study.Periapical radiographs of the impacted mandibular third molars were exposed using the long cone paralleling technique and a digital probe to enable classification of the type of impaction and any other radiographic findings. The long cone paralleling technique was used for this study due to the fact that it is regarded as the technique of choice following its reduced radiation dose; less magnification and demonstration of the true relationship between the bone height and adjacent teeth [10].The impacted mandibular third molars were classified using the winter's classification based on the inclination of the long axis of the impacted third molar to the long axis of the second molar. The tooth was classified as mesio-angular when the impacted third molar is tilted towards the second molar in a mesial direction; disto-angular when the long axis of the impacted third molar is angled distally / posteriorly away from the second molar; horizontal when the long axis of the impacted third molar is horizontal and vertical when the long axis of the impacted third molar is parallel to the long axis of the second molar [11].The impacted mandibular third molars were also classified as partial impaction when the superficial portion of the tooth was covered only by soft tissue but the height of the tooth's contour was below the level of the surrounding alveolar bone and complete impaction when the tooth was completely encased in bone so that when the gingival is cut and reflected back, the tooth is not seen [12]. MethodologyThis was a prospective cross sectional study involving patients presenting with impacted mandibular third molars to the Dental Centre of the University of Benin Teaching Hospital.The data collection instrument was a pre-tested interviewer administered questionnaire. The questionnaire elicited information on demographic characteristics, number and type of impacted mandibular third molar, caries and cervical resorption status of the adjacent second molar and symptoms associated with the impacted mandibular third molar.

“…A recent study has shown that second molars adjacent to absent third molars are at the lowest risk of developing caries and periodontal disease; whereas, second molars adjacent to soft tissue impacted third molars are at the greatest risk [66]. Thus, when a partially erupted mandibular third molar is not removed, good oral hygiene becomes essential to avoid caries [67]. The most important variables when considering caries risk in the second mandibular molar due to a partially erupted third molar are eruption status, type of angulation, and the nature of tooth contact between the molars.…”

“…The most important variables when considering caries risk in the second mandibular molar due to a partially erupted third molar are eruption status, type of angulation, and the nature of tooth contact between the molars. Such factors can be used as predictors to indicate the likelihood of developing caries on the second mandibular molar [67]. Otherwise, if recurrent dental caries occur on the second molar, the third molar must be prophylactically removed [68] (Figure 8).…”

Dental caries is a multifactor disease affecting a significant number of people throughout the world. However, in recent decades the widespread availability of fluoride and other preventive measures have resulted in a decline in the prevalence of caries among children and young adults. Currently, it is accepted that most carious dental lesions are restricted to specific anatomical sites. The aim of this chapter is to review the influence of dental anatomy on dental caries development while taking into account recent findings in cariology. Occlusal fissures in the first permanent molar are generally the first sites in the permanent dentition to develop caries. An increased risk of caries is also found in proximal contacting surfaces between two adjacent teeth. Moreover, a partially erupted tooth, which does not participate in mastication, is also at risk for caries since it may provide a more favorable environment for bacterial accumulation than a fully erupted tooth. Bacterial biofilm on the tooth is frequently a high risk caries environment. Understanding anatomical dental features is of great importance for guiding oral health hygiene and preventive measures. Finally, the development of dental disorders plays an important role in dental caries risk.
