Radiographic Evaluation of Impacted Third Molars and Their Complications in a Group of Iranian Population

Journal of Research and Practice in Dentistry, 2014

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.

Evaluation of the Impact of Impacted Mandibular Third Molars on Surrounding Structures: A Clinical and Radiographic Analysis in Students of Tagore Dental College and Hospital

Biomedical and Pharmacology Journal, 2015

Useful purpose for third molars has become more difficult, especially when one considers that people experience pain and disease when third molars are not extracted, and many other people experience pain and morbidity when they are extracted. Whether there is a need for these teeth in the dentition is a question worth asking? This study aims to present data about the prevalence and distribution of mandibular third molars students of Tagore Dental College & Hospital. The sample of 200 students was selected by Simple Random Sampling Method in the age group between 21 to 25 years. Intraoral periapical radiographs of right and left mandibular third molars were taken and clinical examination was done to assess the presence of pericoronitis, periodontal pocket, proximal caries, root resorption in distal surface of second. On clinical examination, 23% of pericoronitis was present, 12% of periodontal pockets, 8% proximal caries and no resorption were observed. Within the limitations of this study, it was concluded that significantrelatively less impact of mandibular third molar on second molars. Further studies are recommended with increased sample size.

Prevalence and Patterns of Impacted Maxillary third Molar in a Private Dental Institution

SciDoc Publishers, 2021

Tooth impaction can be defined as that failure of the tooth to erupt into its normal physiological position and oftentimes, it is associated with a third molar. Third molar is also known as wisdom tooth, meaning it is the last tooth to erupt into the oral cavity even in the age of adolescent or adulthood. Although third molar impaction remains indefinitely asymptomatic, some individuals may be presented with tenderness and swollen gums. Impacted teeth are commonly treated with tooth removal. Conservative approach is recommended in asymptomatic cases and when the risks of the procedure outweigh the expected benefit. The aim of this study was to investigate the prevalence and pattern of maxillary third molar impaction, angulation and level of eruption among patients treated in Saveetha Dental College. Data collection was done in a university setting. Data regarding patients having impacted teeth were retrieved after analyzing 86000 case sheets. The following parameters were evaluated based on the dental records; age, gender, level of eruption and angulation pattern. Radiographs and intraoral photographs were used to assess the patterns of maxillary third molar impaction. Excel tabulation and SPSS version 23 was used for data analysis. The statistical test used for the demographics was frequency, percentage and for tests of association between categorical variables was Chi-square test. P value less than 0.05 was considered as statistically significant. Women had more prevalence (58.5%) of impaction than men and was seen most in the age group of 21-40 years. 64.6% and 35.4% of the total teeth were 18 and 28, respectively. The most common angulation of impaction in maxilla was vertical (55.4%). Position C impaction had greater occurrence (61.5%) compared to other two levels of impaction. No significant difference was found between right and left sides in maxilla, (p=0.447). There was no significance of angulation and level of impaction with respect to age and gender. Within the limits of the study, impacted maxillary third molars were more prevalent in female and younger patients. Vertical angulation and level C position were more frequently seen in impacted maxillary third molars.

Journal of Medical Science And clinical Research, 2019

The aim of this cross sectional study was to assess the prevalence and pattern of impacted mandibular third molars on digital panoramic radiographs. Methods: In the study we reviewed 745 digital panoramic radiographs of patients treated in our institution from 2017 June to 2018 June. The radiographs were retrieved from the archives of Department of Radiology and were evaluated for the prevalence of impacted mandibular third molars, their pattern of distribution and associated pathological conditions. The study also evaluated presence of other impacted teeth as well as partially impacted mandibular third molars. Results: From the total of 745 radiographs reviewed, a total of 293 impacted teeth were observed. Mandibular third molars (198) were the most commonly encountered impactions, followed by maxillary third molars (69), maxillary canines (11) and supernumerary teeth (15). 135 subjects (18.1%) presented with at least one impacted mandibular third molar. 105 (14.1%) subjects presented with impacted mandibular left third molar and 93(12.5%) presented with impacted mandibular right molar, 22 (3%) and 21(2.8%) subjects presented with partially impacted mandibular right and left molars respectively. The analysis of the pattern of the impacted mandibular teeth showed that majority were in the mesioangular (47%) position, followed by horizontal (32.32%), vertical (15.15%) and distoangular (5.56%) positions. Conclusion: The study revealed that 18% cases showed impacted mandibular third molar, with mesioangular (47%) pattern was more frequent.

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.
