One of the basic requirements for succesfull transplantation is an adequate size of recipient site with sufficientalveolar support. If the transplantation is performed into a fresh extraction site, the recipient site can easily beadjusted to the transplantation. However, the situation is different in patient with premolar aplasia or early molarloss with marked atrophy of the alveolar process, need additional surgical procedures like bone autograft orsplitting osteotomy of the alveolar process. This paper discussed the effect of bone autograft and splitting osteotomyon root development of transplanted immature third molars. The conclusion is these additional surgical prosedureshad a negative effect on the pulpal and periodontal condition of transplantated immature third molars. This may berelated to revascularization disturbances of pulp due to nutrient insufficiency of the recipient site.

Subject. The issues of indications, contraindications and the optimal timing for the removal of abnormally located lower third molars remain relevant in dentistry. Numerous evidence has been accumulated of their negative impact on the formation of the dentofacial system, however, X-ray patterns of patients with this pathology in the process of their formation, development and change in the angle of inclination, as well as the growing problems associated with the growth of these teeth in the dentition and bite have not been studied. The goal is to study the dynamics of the position of the rudiments of the abnormally located lower third molars in the process of their formation and growth and their influence on the state of the dentofacial system as a whole. Methodology. The study involved 28 patients with abnormally located impressive lower third molars, which were divided into 3 groups: in the first (8 people), the second molars were at the teething and growth stage, in the second (12 people) the second molar was in the occlusal plane at the stage closed apex, in the third (8 people) there was a multiple abnormal position of the mesially located teeth from the third molar. All measurements were performed using a virtual measuring device in the image mode of slices with Galileos Viewer software. Results. According to our results, a significant scatter was recorded in the timing of the formation of third molars from the period of mineralization of the crown of the teeth (12―15 years) to the end of growth and root formation (18―23 years). After 23 years, the roots of the abnormally located lower third molars in the patients examined by us had radiological signs of the end of formation (closed apex). Conclusion. Impact lower third molars continue their growth and have a negative effect on the condition of the teeth located mesial. This fact does not depend on concomitant orthodontic pathology, nor on the methods of orthodontic treatment (removable or non-removable equipment).

Abstract Objectives The aim was to evaluate the characteristics of the mandibular third molars, especially in relation to the inferior alveolar nerve. Further aims were to investigate incidental findings in panoramic radiographs in an adult population, and to investigate image quality related to patient positioning. Materials and Methods From a previous study with 451 randomly selected adult participants who lived in Sweden, 442 panoramic radiographs from four dental public health clinics were used. The third molars’ characteristics and relation to inferior alveolar nerve were evaluated. Incidental findings and patient positioning were recorded. Statistical Analysis Frequency analysis was used to investigate the occurrence of all findings and their possible interconnections. Whether the patients’ age or gender had an impact or not was also analyzed. Results The third molars were erupted in vertical position among 73% regardless of age. When retained or semi-retained, they were most commonly in mesioangular positions. The inferior alveolar nerve was located inferior to the roots in 52%, whereas an overlapped position was most common if the third molar was retained (90%), semi-retained (83%) or the age was less than 30 years (66%). Common incidental findings were apical radiolucencies, idiopathic osteosclerosis, and tooth fragments. Suboptimal patient positioning was found in one-third of the radiographs. Conclusions Panoramic radiography is a useful method to evaluate third molar prior to surgical removal and may be the only image required. Most incidental findings on panoramic radiographs does not seem to require any further odontological management.

The aim of the study was to assess the influence of flap designs (Envelope flap (EF) and Szmyd flap (SF)) for impacted mandibular third molar extraction, on periodontal pocket depth (PPD), clinical attachment loss (CAL) and bone levels (BL) of second molar. Sixty patients indicated for third molar extractions with healthy second molars were allocated into two groups: EF and SF (n = 30). Third molars were assessed for angulation, root patterns, depth of impactions and relation with ramus (Pell and Gregory classification). Extraction of third molars was performed and PPD, CAL and BL around second molars at 0, 3 and 6 month (mon) follow-ups (FU) were assessed clinically and radiographically. ANOVA, Chi-square and Fisher’s exact test were employed to compare periodontal factors between EF and SF groups, considering p ≤ 0.05 as significant. Sixty participants with a mean age of 23.22 ± 3.17 were included in the study. Based on angulation, the most common impaction in the EF and SF groups was mesio-angular (EF, 50%; SF, 36.7%). Buccal and distal PPD showed a significant increase (p < 0.001) in both EF and SF patients from baseline to 6 mon. EF patients showed significantly higher distal and buccal CAL (6.67 ± 0.18 mm; 6.91 ± 0.17 mm) and BL (7.64 ± 0.16 mm; 7.90 ± 0.15 mm) as compared to SF patients (CAL, 6.76 ± 0.26 mm; 6.91 ± 0.17 mm-BL, 7.42 ± 0.38 mm; 7.34 ± 0.34 mm) at 6 mon FU. SF showed better soft tissue attachment (PPD and CAL) and bone stability (less bone loss) around second molars compared to EF after third molar extractions regardless of the patient, tooth and operator factors.

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.

ABSTRACT The search for means that enable a better quality of life for postoperative patients should be incessant. The surgical extraction of third molars can result in potential complications such as pain, swelling and trismus, along with discomfort in the recovery phase. Therefore, this narrative review was to analyze, from systematic reviews and randomized clinical trials, the use of low level laser therapy as influencer the clinical state after third molar surgery. Scientific articles were searched through PubMed and Science Direct database. In spite of the evaluated studies have cited the effectiveness of laser therapy such as tissue repair, anti-inflammatory and analgesic, variety of analysis models and diversity of dosimetry leaves a gap on their true efficacy. Based on the research conducted, we suggest the adjuvant use of diode laser GaAlAs with 810 nm (λ), 100 mW constant power and 4 J/cm2 of energy, intra and extra oral form at least three sections to minimize possible occurrences of third molar surgery.

The purpose of this study was to test the effect of the surgical removal of impacted mandibular third molars using piezosurgery versus the conventional surgical technique on postoperative sequelae and bone healing.Material and Methods.This study was carried out as a randomized controlled clinical trial: split mouth design. Twenty patients with bilateral mandibular third molar mesioangular impaction class II position B indicated for surgical extraction were treated randomly using either the piezosurgery or the conventional bur technique on each site. Duration of the procedure, postoperative edema, trismus, pain, healing, and bone density and quantity were evaluated up to 6 months postoperatively.Results.Test and control sites were compared using pairedt-test. There was statistical significance in reduction of pain and swelling in test sites, where the time of the procedure was statistically increased in test site. For bone quantity and quality, statistical difference was found where test site showed better results.Conclusion.Piezosurgery technique improves quality of patient’s life in form of decrease of postoperative pain, trismus, and swelling. Furthermore, it enhances bone quality within the extraction socket and bone quantity along the distal aspect of the mandibular second molar.

Introduction: Crowding in mandibular arch increases with increasing age and etiology of crowding is multifactorial in nature. Role of mandibular third molar in lower anterior crowding remains a topic of controvery over a period of century. The objective of this study was to assess whether there is any correlation between presence of mandibular third molar position and lower anterior crowding. Materials and Method: On the basis of third molar position one hundred and six sample of pretreatment orthodontic patients aged between 17 to 38 years were divided into erupted, erupting and agenesis group. The study was conducted in Peoples Dental College and Hospital from January 2020 to March 2020 after obtaining ethical approval from the institutional review committee. This cross-sectional study was done on dental casts and orthopantomogram; brass wire was used for measuring arch length and digital vernier caliper for measuring tooth material with modified segmental arch analysis method. Result: Among 106 samples collected 55 (51.88%) were female and 51(48.11%) were male and the mean age was 21.53 ± 3.91 years, Chi square and ANOVA test was used for Statistical analysis. This study showed no statistically significant differences between third molar position and lower anterior crowding on right (P= 0.68) and left side (P = 0.45). The study also showed that association between the third molar position and lower anterior crowding is more on left side compared to right side. Conclusion: Mandibular third molars have not statistically significant difference in lower anterior crowding so, extraction of third molars for relieving the anterior crowding is not justifiable

Ameloblastoma is an aggressive slow growing benign epithelial odontogenic tumor usually associated with an unerupted third molar. In this report, we present the case of a 71-year-old male with a large swelling on the left mandibular region causing a remarkable facial asymmetry. After clinical, radiological, and histopathological examinations the diagnosis of conventional ameloblastoma was made. To avoid probable recurrence our treatment choice was a segmental mandibular resection with the placement of a reconstructive titanium plate to maintain the space for subsequent bone graft.

Introduction: Diagnosis and management of impacted mandibular third molars call for a cogent appraisal and treatment choice both for the sick person and the dental practitioner. This academic work scrutinized the pattern as well as treatment of impacted mandibular third molars at the Teem Clinic and Dental Centre, Ekpan, Delta State, in Nigeria.Materials and Methods: This cross-sectional survey involved 131 cases who reported impacted mandibular third molars. The age, gender, impacted tooth, type of impaction, pathological conditions, and treatment proffered were recorded.Results: The male to female ratio was 0.8:1, with an age range of 10 to 40 years. Of the lower third molar impactions 58 (42.0%) were mesioangular, 5 (3.6%) horizontal, 18 (13.0%) vertical and 57 (41.3%) were distoangular. A total of 47 (34.1%) quested for dental attention following varying degrees of pain induced by pericoronitis. Teeth removal was accomplished for 76 (55.0%) owing to carious lesions on the impacted teeth, proximate tooth, or both. Surgical extraction was the option taken in 69 (50.0 %) with caries on the impacted teeth while 3 (2.2%) had to pull out of their teeth done owing to carious lesions on the bordering second molars. In 3 (2.2%) both the impacted third molar and the proximate second molar were decayed. Conclusions: The prevailing indication for pulling out impacted mandibular third molars was acute pericoronitis. Mesioangular sort of impaction was most recurrent and ought to be considered for theplausibility of frequentness of complications.
