OBJECTIVE: This study was conducted to observe the relationship of mesio-angular impacted third molars to the development of distal caries in adjacent second molars. METHODOLOGY: This cross-sectional study was conducted at Nishtar Institute of Dentistry, Multan. Nine hundred and eighty nine periapical, bitewing and Panoramic radiographs were recorded and examined for distally carious second molars and impacted mandibular third molars. SPSS version 23.0 was used for data entry and analysis. RESULTS: Almost 40.8% of the target population reported with distal caries due to third molar impactions. A total of 53.30% of these impactions were of the mesio-angular variety. No distal caries was detected in transverse type of impactions. CONCLUSION: The current study concluded that the prevalence of distal caries in mandibular second molars and the positioning of adjacent impacted mandibular third molars in the dental arch were interlinked. Consequently, extraction of mandibular third molars should be considered to prevent caries and premature loss of second molar teeth.

INTRODUCTION: Impaction may be defined as the failure of complete eruption into a normal functional position of one tooth within normal time due to lack of space in the dental arch, caused by obstruction by another tooth or development in an abnormal position.MATERIAL AND METHODS: A cross sectional descriptive study was conducted on 945 patients (males=591, females=354) aged between 18- 50 years of age who had mandibular third molars impacted. The difficulty index for mandibular third molar for angulation and depth was based on Winter’s classification (1926).RESULTS: The most common type of impaction seen was Mesio- angular with (32%) followed by horizontal 264 (27.8%), then followed by other types. Data was analyzed using Statistical Package for Social Sciences (SPSS) version 23.0CONCLUSION: Impacted third molars are a common observation in routine dental practice. The impaction rate of third molars is higher as compared to other teeth in the dentition. The high prevalence found in the present study, with more than half of these Nepalese adult patients having at least one impacted third molar.

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.

The aim of this study was to compare the post-operative sequelae of removal of impacted third molars in participants treated with conventional flap elevation technique or with a minimally invasive flapless technique. Participants with bilaterally impacted mandibular third molars were included. They were divided into two sites constituting 2 groups. One group was operated by using conventional flap design and elevation and other with flapless technique. Objective clinical parameters were recorded and compared in the post-operative period like mouth opening, swelling, surgical time, and pocket depth. Subjective parameters including pain were also assessed and statistically analyzed. The sites operated in Group II (Flapless technique) had better results (p≤0.05) in terms of pain, swelling, trismus, and pocket depth distal to second molar when compared to Group I (Flap). The flapless technique gives better surgical results and improved healing process after third molar removal and so should be recommended in routine clinical practice.

Introduction: The purpose of this study was to assess the various indications of impacted mandibular third molar removal and pathologies associated with it. Methods: A retrospective cross-sectional study was conducted in the Department of Oral Surgery, Gandaki Medical College. The clinical case records from September 2016 to August 2019 were retrieved, reviewed, and analyzed. Surgically removed impacted mandibular third molars for which orthopantomogram were available and the lesions verified histologically were included in the study. Orthopantomograms were studied to determine the angular position of the impacted mandibular third molars and associated pathology. The data was entered in SPSS 20 and descriptive statistics was applied. Results: A total of 1344 impacted mandibular third molars (Male-709, 52.8%; Female - 635, 47.2%) were surgically extracted during the three-year period. The majority of patients (36.5%) were in the age groups of 25 - 34 years with a higher incidence of mesioangular impaction (33%). Recurrent pericoronitis (62.9%) was the most common indication followed by caries (11.7%). The radiographically detectable lesion was seen in 471 (35%) cases out of which 304 (64.5%) were symptomatic at the time of extraction. Among137 histopathologically diagnosed cases, chronic inflammatory lesion (76, 55.9%) was the most common finding. Conclusion: Awareness of the indications for removal of impacted mandibular third molars helps in proper management and prevention of future complications associated with retention and delayed extraction of such teeth. So, regular and periodic clinical and radiographic examination is required for patients with impacted mandibular third molars.

ABSTRACT Objectives: To investigate factors associated with spontaneous mesialization of impacted third molars after second molar protraction to close the space caused by a missing mandibular first molar (L-6) or retained deciduous mandibular second molars with a missing succedaneous premolar (L-E). Materials and Methods: Panoramic radiographs of patients treated with mandibular second molar protraction to close the space due to missing L-6 or L-E (14 males, 36 females, mean age = 18.6 ± 4.4 years) were analyzed before treatment (T1) and after second molar protraction (T2). Factors associated with the amount of third molar mesialization were investigated using regression analyses. Results: Mandibular second molars were protracted by 5.1 ± 2.1 mm and 5.8 ± 2.7 mm, measured at the crown and root furcation, respectively. After second molar protraction, third molars showed spontaneous mesialization by 4.3 ± 1.6 mm and 3.8 ± 2.6 mm, measured at the crown and root furcation, respectively. Nolla's stage of the third molar at T1 (B = 0.20, P = .026) and second molar protraction time (B = 0.04, P = .042) were significantly associated with the amount of third molar mesialization. Conclusions: Greater third molar mesialization was observed when Nolla's stage of the third molar was higher before treatment and when the second molar protraction time was longer.

ABSTRACT Objective:  To investigate (1) whether vertical eruption of impacted third molars improves after mesialization of second molars and (2) what factors affect the vertical eruption of impacted third molars when space caused by missing molars is successfully closed by mesialization of the second molar using miniscrews. Materials and Methods:  The treatment group (Group 1) included 52 patients who had (1) missing mandibular first molars (ML-6) or missing deciduous mandibular second molars (ML-E), (2) initially impacted mandibular third molars, and (3) successful space closure of the edentulous area with orthodontics. Panoramic radiographs at start of treatment (T1) and at time of space closure (T2) were collected. The control group (Group 2) included 46 nonedentulous patients with impacted mandibular third molars without molar protraction treatment. Panoramic radiographs with similar T1/T2 treatment times were selected. Nine measurements were obtained regarding horizontal available space, vertical eruption, and third molar angulation. Results:  Third molars erupted vertically an average of 2.54 mm in Group 1 compared with 0.41 mm in Group 2. Age, gender, Nolla stage, and angle of the third molars did not show significant correlations with the vertical change of the impacted third molars, whereas the depth of third molar impaction and available space showed significant correlations. Conclusions:  Impacted mandibular third molars vertically erupt as a result of uprighting with mesialization of the second molar, and vertical eruption is affected by the initial vertical location of impacted third molars and available space.

Aim: To analyse early recognition of the distal cervical caries of mandibular second molar caused by impacted mandibular third molar, to correlate oral health and caries status and to find out the average age groups and gender affected by impacted third molar Methods: A cross-sectional survey of 300 participants was conducted over a 15-month period at Rehmat Memorial Hospital, Abbottabad. 300 participants having impacted third molar having distal cervical caries in mandibular second molar were analyzed clinically and radiographically. Data was analyzed using SPSS version 23.0 Results: the demographic data of 300 patients with impacted mandibular third molars were analyzed. 64% were male and 36% female that have extractions due to impaction. Caries caused in more than half of participants by mesioangular impaction, which was 52%, 3% due to distoangular, 26% due to distal, and 18% due to horizontal impaction. In 63.25% of cases, teeth were lost due to caries, periodontitis caused 20.25% of tooth loss, pericoronitis 7.75%, orthodontics 3.75%, prosthodontics 1.2%, trauma 1%, and other factors were 2.5%. study reveals that 30.5 % of the extractions were done from 21 and 30 years and 23 %of extractions were performed. 40% of those who took part in the study did not brush their teeth. Socioeconomic status also has a great impact on tooth extractions. Conclusion: After conducting this study, it was concluded that there was a relationship between the prevalence of distal cervical caries in mandibular second molars and the placement of neighbouring impacted mandibular third molars. As a result, the extraction of mandibular third molars should be done to avoid cavities and premature tooth loss in the neighboring molar.

Introduction: The third molar is undoubtedly the most variable tooth in the human dentition, and also the most common tooth to become impacted due to it being the last tooth to erupt into the dental arch The aim of research is to obtain the prevalence of the mandibular third molar (M3) impaction among the patients attending the Radiology Clinic. Methods: The type of research conducted was a descriptive research. The sampling was purposive, drawn from a population of 1451 digital panoramic radiographs taken from January – December in the year 2010, of which 392 samples were included in the survey, with patient ages ranging between 18 – 59 years at time of exposure. The position of the M3’s was assessed using the Pell and Gregory and, Winter’s impaction classification. Results: The prevalence of impacted mandibular M3’s in this study is 76.8% overall. Of the impacted mandibular M3’s present, 76.1% were bilateral impactions and of these bilateral impactions 50.7% are similar in impaction classification. Of the mandibular M3’s examined, 40.1% are in a vertical angulation, 33.3% mesioangular, 23.5% horizontal and 3.1% distoangular. The three most common types of impaction according to the Pell and Gregory classification are IIB at 38.5%, IA at 36.8% and IIA at 18.8%. Conclusion: Prevalence of  mandibular third molar of the patients attending the Radiology Clinic is 76.8%.

Introduction: Impaction may be defined as the failure of complete eruption into a normal functional position of one tooth within normal time due to lack of space in the dental arch, caused by obstruction byanother tooth or development in an abnormal position. The mandibular third molar is the most frequently impacted tooth. The incidence varies from 9.5% to 68% in different populations.Methods: The study was conducted in Department of Oral Surgery, Faculty of Dentistry, University in Sarajevo. Study represents retrospective analysis of panoramic radiographs (orthopantomograms) of patientsreferred to Department of Oral Surgery from January 2010 to February 2013 with indication for surgical removal of impacted third molars.Results: Of the 2000 radiographs, 761 presented with at least one impacted third molar (38%). A total of 1034 impacted mandibular third molars were present (51.7%). The most common age group was thirddecade (61.2%). Signifi cant statistical difference in incidence of third molar impaction was found between females and males (p<0.05), but there was no statistical difference in incidence in urban and suburbanpopulation (p=0.374). Vertical angulation was the most common pattern of impaction (65%). Frequency of third molars erupted into their normal position (class IA) was 42%. Impacted mandibular molars wereassociated with periodontal pockets in 134 (6.5%) cases and with dentigerous cysts in 5 cases (0.2%).Conclusion: The present study provides useful data regarding the clinical status of third molars in population of Bosnia and Herzegovina.
