Early Postoperative Masticatory Efficiency After Surgical Extraction of a Partially Impacted Mandibular Third Molar

Abstract The extraction of mandibular third molars is a traumatic procedure accompanied by marked clinical symptoms in the postoperative period. The aim of the present study was to determine the effects of the removal of a partially impacted mandibular third molar on the masticatory efficiency in patients in the early postoperative period. Material and methods. A total of 47 participants, divided into two groups, took part in this pilot study. The first group included 33 patients with a mean age of 18.3 years (SD = 0.9 years), defined as the Control group; the second group involved patients with a mean age of 33.3 years (SD = 1.86), referred to as the Clinical group. The masticatory efficiency of the Clinical group patients was objectively double-checked using a Protab® test bite: once during the preliminary examination (prior to extraction of the wisdom tooth) and again 7 days after the surgical removal of the wisdom tooth. A sieve analysis was applied to determine the artificial test bite particle size and size distribution following mastication. Feedback on the Clinical group patients’ assessment of any subjective complaints was obtained through a questionnaire containing two questions considered relevant to patients’ masticatory efficiency. The data from the sieve analysis of each fraction were analyzed using the Statistics Software Package for Epidemiological and Clinical Research (IBM SPSS V.20.00). Results. The data processing of all parameters tested prior to and after extraction of the wisdom tooth revealed statistically significant differences. Only the duration of chewing after the third molar extraction matched the chewing duration in the healthy control subjects (p = 0.198). The analysis of the feedback on the self-assessment of patients from the Clinical group demonstrated that prior to extraction all subjects (100%) experienced pain to a varying degree, whereas in half of the patients (50%) the pain disappeared following extraction. The Spearman’s test for correlation between mean particle sizes as well as the questionnaire feedback indicated a strong positive relationship with food trapping. Accordingly, the larger mean particle size was linked to the self-assessment of food trapping around the wisdom tooth prior to extraction (Spear-man’s Rho = 0.57, p = 0.032). There was also a correlation between the chewing time and the sensation of pain in the teeth adjacent to the extraction wound. The results suggested that the shorter duration of chewing was associated with a greater sensation of pain (Spear-man’s Rho = -0.61, p = 0.026). Conclusion. The eruption of mandibular third molars causes difficulties in the masticatory process. A positive trend was observed towards normalizing of the chewing duration following extraction (t = -1.356, p = 0.198).

ABSTRACT The purpose of this study is to analyze the incidence of complications in a group of 171 patients in whom extractions of impacted mandibular third molar have been performed by two oral surgeons between the period April 2010 and March 2012. This retrospective study comprises evaluation of 270 impacted mandibular third molars which were classified into two groups A and B on the basis of procedure of osteotomy only and osteotomy and odontotomy both respectively. Total no of complications reported were 40 (14.81%). Maximum no of cases reported alveolar osteitis (AO) (11.11%) while other complications reported root tip fractures (2.22%), lingual nerve parasthesia and TMJ problems (each 0.74%) in descending frequency. Conclusion drawn is that the risk of complications in extractions of impacted mandibular third molars always exists, and extractions associated with both osteotomy and odontotomy are associated with higher risk of complications.

Abstract Objective: To test the hypothesis that there is a relationship between forward mandibular third molar migration and root curvature of the mandibular third molars. Materials and Methods: The study is comprised of 64 patients who had a history of unilateral mandibular first molar extraction before 16 years of age with no other missing teeth or prosthetic restorations in the mandible. The extraction space was fully or partly closed. The mean remaining space was 1.1 ± 0.41 mm. The root angles for the mesial and distal roots of the mandibular third molars were measured on the panoramic radiographs by calculating the differences between the angle formed by the long axis drawn perpendicular to the occlusal plane of the crown of mandibular third molar and the central line of the lower one ninth of the root through the root apex. The differences between the extracted and nonextracted sides for mesial and distal roots were analyzed using a paired sample t-test. Results: Both mesial and distal roots were approximately 8° more vertical on the extraction sides than on the nonextraction sides. The differences were statistically significant. Conclusion: Mesial tooth migration of mandibular third molars reduces the amount of root curvature developing on this tooth.

OBJECTIVE: To determine the frequency of mandibular third molar impaction in different vertical skeletal facial types. METHODOLOGY: Data was collected using pre-treatment records including orthodontic files, pre-treatment lateral cephalograms and OPGs of 90 orthodontic patients. Patients from both genders were included. The age group of selected patients was 18-30 years. Vertical skeletal malocclusion was measured using facial angle and mandibular plane angle on cephalogram to group the subjects into Mesiofacial, Brachyfacial and Dolichofacial patients. Third molar eruption status was assessed using OPG. RESULTS: Results showed that erupted third molars were mostly found in brachyfacial patients. Among 32 erupted mandibular third molars, 16 belong to brachyfacial, 11 belonged to mesiofacial and 5 belonged to dolichofacial group. Complete impaction of mandibular third molar was most common among dolichofacial patients. Among 29 completely impacted mandibular third molars, 14 belong to dolichofacial, 9 belonged to mesiofacial and 6 belonged to brachyfacial group. No significant difference was found for partially impacted third molars among the three groups of facial types. There was higher prevalence of mandibular third molar impaction in females as compared to males. CONCLUSION: Frequency of third molar impaction was found to be highest in dolichofacial patients and lowest in brachyfacial patients due to forward direction of mandibular growth contributing to greater resorption of the anterior border of ramus and the additional space required for third molar eruption.

Two cases of calcifying cystic odontogenic tumor (CCOT) of the dental follicle in an impacted third molar without clinical and radiological evidence are reported during routine histopathological examination. In both the cases left mandibular third molar was mesioangularly impacted with pericoronal radiolucency of less than 2.5 mm, which was not indicative of any pathology. As a routine protocol (which is not practiced widely) of our institution, dental follicles associated with extracted molars were sent for histopathological examination. Histopathological features were consistent with CCOT with pathognomonic ghost cell transformation of odontogenic epithelium. The patients were followed for one year with no recurrence. This paper emphasizes the importance of routine histopathological examination of dental follicles associated with asymptomatic impacted teeth without any clinical or radiographic evidence of follicular lesion.

Abstract Background To evaluate the associations of impaction patterns of mandibular third molars (M3Ms) with pathologies caused by them. Methods In this study, 262 patients with 432 impacted M3Ms were included. The pathologies include pericoronitis, mandibular second molar (M2M) caries, and M2M distal periodontal pathology. The impaction patterns of M3Ms and the pathologies were examined, and the M2Ms outcomes after the surgeries were evaluated. χ2 test was used to analyze the data and a P value of <0.05 was considered statistically significant. Results Pericoronitis was the major symptom in all patients, whereas the propensities of M2M distal caries and periodontal pathologies increased in older patients. Soft tissue impacted and vertically angulated teeth were more associated with the pericoronitis (p <0.05); Mesio-angular impacted teeth in less deep positions had greater risks of M2Ms distal caries (p <0.05); Mesio-angular and horizontal impacted teeth in relative deep positions were more likely to cause M2Ms distal periodontal pathologies (p <0.05). Conclusions Extractions of soft tissue impacted teeth in vertical angulations should be considered. While removals of mesially and horizontally angulated or bony impacted teeth could be delayed.

Abstract OBJECTIVE: To investigate the relationship between the presence and dynamics of mandibular third molar development and the occurrence and amount of late mandibular incisor crowding. MATERIALS AND METHODS: Dental plaster casts and panoramic radiographs of 72 orthodontically untreated subjects from the Nittedal growth study, Norway were analysed. The subjects were recalled for check-up at 12, 15, 18 and 21 years of age. Mandibular incisor crowding was assessed using the Little’s irregularity index and dental maturation of the third molars by the Cameriere’s index.RESULTS: The majority of the subjects (64%) had ≥1mm increase in irregularity; 22% experienced increase of 0.1-0.9mm and 14% had unchanged or decreased irregularity. Incisor irregularity increased with age, regardless of absence or presence of third molars. The amount of change in incisor irregularity from 12 to 21 years did not differ significantly between subjects with hypodontia of third molars, extraction and those with third molars present. No differences were observed between erupted, unerupted or impacted third molars. No correlation was found between the amount of change in irregularity and maturation of the third molars.CONCLUSIONS: Occurrence and amount of mandibular late incisor crowding is not significantly influenced by presence or development dynamics of mandibular third molars.

Extraction of mandibular third molars is a common procedure in oral and maxillofacial surgery. There are studies that simultaneously predict the extraction difficulty of mandibular third molar and the complications that may occur. Thus, we propose a method of automatically detecting mandibular third molars in the panoramic radiographic images and predicting the extraction difficulty and likelihood of inferior alveolar nerve (IAN) injury. Our dataset consists of 4903 panoramic radiographic images acquired from various dental hospitals. Seven dentists annotated detection and classification labels. The detection model determines the mandibular third molar in the panoramic radiographic image. The region of interest (ROI) includes the detected mandibular third molar, adjacent teeth, and IAN, which is cropped in the panoramic radiographic image. The classification models use ROI as input to predict the extraction difficulty and likelihood of IAN injury. The achieved detection performance was 99.0% mAP over the intersection of union (IOU) 0.5. In addition, we achieved an 83.5% accuracy for the prediction of extraction difficulty and an 81.1% accuracy for the prediction of the likelihood of IAN injury. We demonstrated that a deep learning method can support the diagnosis for extracting the mandibular third molar.

Background: Mandibular third molar is the most commonly impacted tooth, and its removal is a frequently performed dentoalveolar procedure. It is important to know the prevalence rate in a particular community.Objective: This article aims at evaluation of angulation, ramus relationship and depth of impacted mandibular third molars among patients visiting a private dental clinic in Sultanpur Lodhi.Methodology: 150 patients presenting with 228 cases of lower third molar impaction were included within this study. IOPAR and where necessary, OPG was used for radiographic assessment. Age, sex and tooth number were recorded in each patient on a specially designed performa. Angulation was determined using winter’s method whereas assessment of ramus relationship and depth was done using Pell and Gregory's method.Results and Conclusion: The age of patients ranged from 21-43 years with mean age of 26.6 years. Males showed preponderance to mandibular M3 impaction (54%) in our study, and right side was found more frequently involved (53%). Radiographic assessment revealed that mesioangular impaction (45.2%) was the most prevalent angular pattern followed by vertical, distoangular and horizontal types, and Class 2 Position A (29.4%) most common and Class 1 Position C the least common type of impaction depth and ramus relationship.

Mandibular Third Molars

Dentigerous cysts are one of the most prevalent types of odontogenic cysts and are associated with the crown of an unerupted tooth, especially of the mandibular third molar. In this study, the characteristics of a dentigerous cyst developed around a mandibular third molar on panoramic radiographs were investigated. The panoramic images of 257 consecutive dentigerous cyst cases associated with a mandibular third molar were analyzed. The mean age of the patients was 45.9 ± 13.3 years. The size of the cyst did not significantly correlate to the age of the patient. The unilocular type (89.1%) and the crown side type (68.5%) were significant. The associated mandibular third molars had a high frequency of class III (64.6%) and position B (48.3%) in Pell and Gregory classification and of horizontal position (36.3%) in angulation. Dentigerous cysts were thought to originate and grow commonly around deeply impacted third molars. The associated third molar with dentigerous cyst tends to have a mesial inclination. Dentigerous cysts do not appear to develop gradually after the crown formation has finished, but arise at various periods randomly.
