Abstract 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.

A 37 years, the old male patient reported the chief complaint of inability to open mouth since 10-11 months and recently pain and swelling resulting from wisdom teeth of both sides limited the mouth opening severely (<9mm, less than one finger opening) that he could not take solid food properly. After partial relief and mouth opening (12mm) with antibiotic therapy, the patient was examined and diagnosed with oral submucous fibrosis (osmf) along with impacted molars on both sides. Treatment was planned with a conservative approach consisted of pharmacotherapy and physiotherapy for osmf and surgical removal of impacted third molars of both sides. Mouth opening was improved gradually (>15mm after 3 weeks, >22mm after 6 weeks,>27 mm after 9 weeks).

Disease Free

In 2000 the National Institute for Health and Care Excellence (NICE) published clinical guidance that advised against the removal of disease-free wisdom teeth (prophylactic removal).1 This was mainly driven by the perception in the UK that up to 44% of all removed third molars were disease free and consequently had no clinical indication for removal.1,2 But does the NICE guidance, which has become akin to scripture on this issue, have everything right?.

Mandibular Third Molars

A supernumerary tooth is that which is present additionally to the normal series and can be found in any region of the dental arch. An impacted tooth is defined as the one which is embedded in the alveolus, so that its eruption is prevented, or the tooth is locked in position by bone or the adjacent teeth. The occurrence of multiple supernumerary teeth in only one patient in the absence of an associated systemic condition or syndrome is considered as a rare phenomenon. The occurrence of supernumerary teeth in the lower molar region is rare. A prevalence of less than 2% of cases occurring in this region has been estimated. Their occurrence presents a clinical problem for orthodontists and oral surgeons. The cause, frequency, complications, and surgical operation of impacted teeth are always interesting subjects for study and research. An impacted tooth can result in caries, pulp disease, periapical and periodontal disease, temporomandibular joint disorder, infection of the fascial space, root resorption of the adjacent tooth, and even oral and maxillofacial tumours. The management of impacted wisdom teeth has changed over the past 20 years from removal of nonsymptomatic third molars to simple observation. The aim of this paper is to present a rare case of bilateral multiple impacted supernumerary mandibular third molars.

Abstract 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

Background. Coronectomy of the wisdom teeth is an alternative surgical procedure to tooth extraction, which aims to preserve the roots of the wisdom teeth in the dental socket after surgical separation of the crown, in order to avoid the injury of the inferior alveolar vascular-nervous bundle. Purpose. Minimizing the damage to the inferior alveolar nerve when extracting lower third molars caused by the intimate relationship between the nerve and the roots of the teeth, by using the technique of coronectomy, or intentional root retention. Material and Methods. Patients who reported to University Dental clinic during the period 2020–2021 for surgical removal of impacted L3M were screened for nerve–root relationship with OPG or CBCT. 15 patients underwent coronectomy as a procedure to remove the crown and upper third of the roots of a lower third molar to reduce the risk of damage to the inferior alveolar nerve. Results. 15 patients were enrolled in this study, with a total of 17 lower third molars. Sixteen sites healed primarily, but in 1 case the sockets on both sides opened and failed to close secondarily. In this case, the root fragments were later removed and found to be mobile. Conclusion. Coronectomies are safer to perform than complete extractions in situations in which the third molar is in close proximity to the mandibular canal. The technique appears to be associated with a low incidence of complications and the removal of remaining roots is required in around 6-7% of cases due to the mesial migration of the fragment and not any symptoms or reinfection.

Distal Cervical Caries (DCC) of the mandibular second molar has become a more frequent complication of third molar impaction as a direct consequence of the introduction of NICE's guidance on the management of wisdom teeth. NICE's tenet that disease free impacted third molars can be retained is contradicted by the development of DCC on the second molar as its diagnosis asks the simple question of why the impacted third molar was not removed before DCC occurred. This paper aims to address the features of DCC associated with the second molar and outlines how dentists should address its diagnosis but, more importantly, how to recognize those at risk and how patients should be managed. CPD/Clinical Relevance: Clinical management of impacted third molar teeth.

Abstract Objective: To test the null hypothesis that agenesis of wisdom teeth is not related with any particular craniofacial morphology. Materials and Methods: Ninety-seven patients (aged 13–19 years) were selected and divided into three groups: (1) bilateral agenesis of maxillary third molars, (2) bilateral agenesis of mandibular third molars, and (3) control group without agenesis. Presence or absence of third molars was determined using ortopantomographs. Cephalometric analysis was carried out from lateral teleradiographs, which included linear, angular, and proportional measurements. When data obtained were distributed normally it was analyzed by means of single-factor variance analysis and the Scheffé test (P &lt; .05). When data did not show normality, the Kruskal-Wallis test (P &lt; .05) and the Mann-Whitney test were applied using Bonferroni correction (P &lt; .017). Multivariance discrimination analysis was also carried out. Results: Values obtained for the mandibular plain of Groups 1 and 2 were significantly lower than those of the Control Group (P =.00 and P =.00, respectively). For Group 2 lower face height was significantly less than for the control group (P =.01), whilst the mandibular arch and the articular angle were significantly greater than in the Control Group (P =.000 and P = .02, respectively). Multivariance discrimination analysis obtained a correct classification in 58.8% of cases. Conclusion: The hypothesis is rejected. Agenesis of the maxillary third molars was related to a reduced mandibular plane angle. Patients with agenesis of the mandibular third molars showed a diminished lower third and a mandibular morphology characteristic of the brachyfacial pattern.

Controversial Topic

Whether to extract or retain wisdom teeth present in a fracture line is a controversial topic. This study reviewed the records of all patients who had mandibular wisdom teeth at the time of the injury, and had an open reduction and internal fixation procedure between January 2009 and January 2012. The cohort of patients who concomitantly had their wisdom tooth extracted at the time of fixation had a greater complication rate (24.3%) compared with patients who did not (14.9%). This suggests that if third molars in the line of a fracture have caries, are fractured, show signs of pericoronitis, are periodontally involved, or are interfering with the occlusion are extracted at the time of fixation, this will increase the incidence of complications.

The Individual

The article presents a theoretical synthesis and a new solution of the scientific problem, which consists in determining the sexual and individual polymorphism of third molars through the age aspect. The review of the relevant literature, the results obtained by analysing orthopantograms of people at the first period of adulthood, and studying randomly selected third molars removed for various clinical reasons (more than 140 samples) are presented. It has been shown that erupted third molars considerably vary in size and shape that is due to different combinations of configurational relationship between the crown and root parts. This depends on the location of opposing teeth in the dentition and sex as well, but does not correlate with age. Moreover, the entire range of individual and sexual variability of the third molars is limited by two extreme forms: very large teeth with long divided roots or with a quadratubercular crown, which are not significantly different from typical molars, and very small analogues with one fused root section, the crowns of which resemble small permanent teeth. Between these forms all other are distributed and most numerous types we called as intermediate. The data analyzed indicate that the individual variability of the size of the teeth in length depends entirely on the length of their root sections. It has been established that, relative to the crown-root index, there are three forms distinguished among the third molars: long-root; medium root and short root. At the same time, long-root forms are found mainly among male teeth, mid-root forms are more characteristic of female wisdom teeth, and short-root forms of third molars do not show a sex difference. The results obtained demonstrate that the orthopantogram of the dentofacial system in humans (aged 22 to 35 years) reliably reveals an inverse relationship between the longitudinal size and the term of eruption of the third molars. The systematic approach used in the work made it possible to bring the varied polymorphism of the third molars into a certain order, highlighting the most indicative features for their classification.
