Radiographic Assessment of Impacted Mandibular Third Molar- An Ex-vivo study
Journal of Pharmaceutical Research International, 2021
Background: Mandibular third molars are the most commonly impacted teeth and frequently associated with various pathologies including infection, traumatic, inflammatory and cystic lesions necessitating their surgical removal. To avoid complications, clinical and radiographic evaluation of impacted teeth is essential to provide information about tooth anatomy, position and condition of the surrounding bone. Aim: To evaluate impacted mandibular third molars (IMTM) with the help of panoramic radiographs for the type of impaction, available third molar space, level of eruption, and relation to the inferior alveolar nerve (IAN). Materials and Methods: Total 600 patients were selected and were divided into three groups; group I (18-27 years), group II (28-37 years), and group III (>38 years). Digital OPG were traced and evaluated for angulations, third molar space, level of eruption, and relation of third molar roots to IAN canal. The observations were subjected to statistical analysis...

Aim To study the incidence of mandibular third molar impaction in relation to type and side of impaction, age and sex of patients and indications for its surgical removal through data collected from a single institute over a period of 3 and half years. Methods The records of 1198 patients who underwent the surgical removal of impacted mandibular third molars were reviewed retrospectively. Records were divided into groups according to sex, age, type and side of impaction. Radiographs were studied to determine angular position of impacted mandible third molar. Results We found that there was a high incidence of mesioangular lower third molar impaction (33.97 %), highest number of patients were found in 15-30 years of age group (48.33 %), a left side (56.93 %) was more commonly involved, female predominance (63.44 %) was observed and recurrent pericoronitis (33.81 %) was the most common indication. Conclusion Awareness of the indications for surgical removal of impacted mandibular third molar to the patients will help to avoid future risk of complications and morbidity associated with the same. This will not only help in saving time and money but also prevents the psychological trauma associated with delayed treatment. Removal of only symptomatic IMTM seems to be the logical choice in view of financial constraint in developing countries like India but at the same time early removal offers freedom from future complications in selected cases. So surgeons should apply a meticulous approach in selecting the patients for SRIMTM.

ISRN Dentistry, 2011
Objective. The study was to evaluate impacted mandibular third molars (IM3M) for their angulation, level of eruption, third molar space and relation of inferior alveolar canal with their roots. Methods. Total 988 IM3M were studied in 578 individuals of age 18 years and above, dividing them into three groups i.e. symptomatic, asymptomatic and radiographic only. Individuals were also divided according to age, sex and side of IM3M (right or left). Panoramic radiographs were obtained after written consent and traced. ℵ2-test was applied to check inter-group and intra-group significance. Result. Out of 578 individuals 307 (53.11%) were males and 271 (46.89%) females. Maximum number of IM3M were in 18-27 years age group (398 i.e. 68.89%). Out of 988 IM3M, 39.93% were vertically placed. 61.84% IM3M were found at level A. Class II (79.65%) was the most common relation for third molar space. Notching (12.55%) was most common true inferior alveolar canal and IM3M root relation whereas superim...

Aims and Objectives: This study was conducted to compare the clinical assessment of impacted third molars of mandible with panaromic radiograph (OPG) and intraoral periapical radiograph (IOPA) and to assess the efficacy of IOPA and. Moreover, we corroborated the OPG and IOPA findings of impacted mandiblar third molar root apex to inferior alveolar canal. Materials and Methods: A total of 200 patients with pericoronitis were examined who were indicated for surgical extraction, among which 50 patients were selected for the study. All the patients underwent a radiographic survey with a digital OPG and IOPA of impacted mandibular third molars, along with clinical survey for anatomic relationship, type of impaction, space available, position in relation to second molar, number of roots, root curvature, and proximity of nerve canal. The data was subjected to statistical analysis. The Statistical Package for Social Sciences version 4.0.1 software was used for analyzing the collected data. Results: The study revealed that IOPA was more accurate in determining a majority of the factors affecting the third molar surgery, including relationship of the external oblique ridge (IOPA vs OPG = 96%:90%), anteroposterior relation with ramus (IOPA vs OPG = 70%:66%), vertical depth of impaction (IOPA vs OPG = 72%:68%), number of roots (P = 0.013), morphology of roots (IOPA vs OPG = 96%:90%); however, OPG was found to be accurate in evaluating the type of impaction (IOPA vs OPG = 88%:94%), canal relation, along with root of impacted molar (IOPA vs OPG = 74%:86%). Conclusion: To conclude, although IOPA has a marginal angle over OPG in assessing various parameters, only the number of roots have a greater accuracy (P < 0.0013) in IOPA than with OPG. However, the OPG is the better choice to be considered when the patient is associated with trismus.

Background and aim: An impacted tooth is a tooth that did not grow on its expected time because of an incorrect position or lack of space. The impacted third molar is the most common impacted tooth. In the present study, the presence of the impacted third molar teeth and their complications in the panoramic radiography of patients were evaluated. Methods and materials: The frequency of impacted third molars, in two jaws and two genders, their position (impaction depth and angulations), their influence on adjacent teeth and their relations to inferior alveolar canal were evaluated in 2000 panoramic radiography of patients who were over 20 years old. Results: 333(16.65%) patients [161(48.3%) men and 172(51.7%) women] with mean age of 30.32 ± 7.22 years (between 20-68 years old) had impacted teeth. 313 cases only had impacted third molars, 16 cases had other impacted teeth and 4 patients had both impacted third molar and other impacted teeth. Prevalence of impacted wisdom teeth is in mandible more than maxilla and in women more than men. The mesioangular angulation in mandible and upright angulation in the maxilla were the most common angular position. Type B in the mandible and type C in the maxilla were the most common types of impaction's depth. Most of the mandibular and maxillary impacted third molars showed complete root development. Higher frequency of distal caries or defects of the adjacent second molars was found in the mandible. Conclusion: Frequency of impacted third molars in mandible was more than maxilla. Also impacted third molars were found in women more than men. With regard to mandibular third molars, mesioangular and type IB were the common pattern.The relationship between the position of the tooth and distal caries of second molar will be an interesting finding and has clinical importance.
Cause and Effect Relationship Between Mandibular Third Molar Impactions and Associated Pathologies
To determine and evaluate the possible causes for the development of pathological conditions associated with impacted mandibular third molars. Methods: Sample comprised of 2292 impacted mandibular third molars reported to the Oral Diagnostics and Oral and Maxillofacial Surgery unit from December 2012 to June 2014. Radiographs were analysed for the presence along with type of impactions and associated radiolucencies. Excised lesions underwent histopathological examination. Chief complaints were recorded as pain, swelling, trismus and sensitivity in area of impaction. Results: Male to female ratio was 1:1.7 with leading age range of 25-34 years. Prime chief complaint was pain (65.4%) with mesioangular (54.7%) as commonest type of impaction. Foremost associated pathology was pericoronitis (70.9%) followed by cysts (16.7%), facial space infection (9.9%) and tumors (2.2%) respectively. Maximum cysts (n=267) were associated with mesioangular impactions with periapical cyst in mainstream (87.9%). Majority of tumors (33.9%) were related to mesioangular impactions among which squamous cell carcinoma was maximum (n=12). Conclusion: The early recognition of causes and monitoring of mandibular third molar impactions is imperative from a therapeutic point of view. To avoid prospective development of pathologies, we recommend regular screening of these teeth for appropriate clinical assessment and treatment planning.
Impacted mandibular third molars among patients attending Hospital Universiti Sains Malaysia
2009
The aim of this study was to identify the position of impacted mandibular third molars based on the classifications of Pell & Gregory and Winter, the indications for extraction, and the relation of post-operative complications and position. Records of patients who attended Hospital Universiti Sains Malaysia between January and December 2007 for surgical removal of mandibular third molars were reviewed. The angulation type, width and depth of impaction were determined by reviewing the orthopantomograms. The indications of extraction and occurrence of any post-operative complications were recorded. A total of 238 impacted teeth were surgically extracted from 194 patients (97 males, 97 females). The reasons for extraction include recurrent pericoronitis (43.1%) followed by prophylactic purposes (33.5%). Mesioangular impactions accounted for 52.3% and Class IIA position of impaction accounted for 45.7% of extractions. The most common post-operative complication was persistent pain and swelling (14.7%) followed by trismus (4.1%) and dry socket (3.0%). There was no significant relationship between the angulation, width and depth of impaction and the occurrence of complication. Mesioangular type and Class IIA position of impaction were the most common impaction. Although the association was not significant, high frequency of post-operative complications was observed in mesioangular, horizontal, IIA and IIC positions.
