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.

COMPLICATIONS AFTER EXTRACTION OF IMPACTED THIRD MOLARS-LITERATURE REVIEW
Third molar surgery is the most common procedure performed by oral and maxillofacial surgeons worldwide. This article addresses the incidence of specific complications and, where possible, offers a preventive or management strategy. Complications, such as pain, dry socket, swelling, paresthesia of the lingual or inferior alveolar nerve, bleeding , and infection are most common. Factors thought to influence the incidence of complications after third molar removal include age, gender, medical history, oral contraceptives , presence of pericoronitis, poor oral hygiene, smoking, type of impaction, relationship of third molar to the inferior alveolar nerve, surgical time, surgical technique, surgeon experience, use of perioperative antibiotics, use of topical antiseptics, use of intra-socket medications, and anaesthetic technique. For the general dental practitioner, as well as the oral and maxillofacial surgeon, it is important to be familiar with all the possible complications after this procedure. This improves patient education and leads to prevention, early recognition and management.
Indications for surgical extraction of third molars: a hospital-base study in Accra, Ghana
International Journal of Medicine and Biomedical Research, 2014
Background: Third molar extraction is one of the most frequent procedures in oral surgery practice. Aim: To investigate the indications for this procedure in patients referred to a private and the oral surgery clinic of the Korle Bu Teaching Hospital, (KBTH), both in Accra, Ghana. Methods: This is a retrospective study of 402 patients treated between January 2007 and June 2009. Age and sex, indication for extraction; tooth extracted, type of impaction were analyzed. Results: 192 (47.8%) were male and 210 (52.2%) female; with male: female ratio of 1:1.1. Their age ranged between 15 and 70 years with a mean of 24.8 years. 243 (60.5%) were between 21-30 years, 87 (21.6%) between 31-40 years and 48 (11.9%) were over 40 years old. The commonest indication for surgery was pericoronitis (49.25%) followed by dental caries (26.1%). 94.8% involved the mandible and 5.2% the maxilla. 47.8% were in mesioangular, 26.1% in vertical, 22.4% horizontal and 3.7% in distoangular positions. Alveolitis sicca dolorosa and prolonged numbness of the lower lip were two main associated complications seen in six patients. Conclusion: The main reason for surgical extraction of impacted third molars was recurrent pericoronitis, occurring mostly in a relatively younger age group; followed by dental caries then prophylactic surgical extraction.

Background: There are controversies and debates over the risks associated with the retention of asymptomatic impacted mandibular third molars when compared with the need for their extraction. Objective: To determine the incidence and types of complications after the surgical extraction of asymptomatic impacted mandibular third molars. Patients and methods: This was a four-year prospective, single blinded, clinical study, carried out at the Dental and Maxillofacial Surgery Clinic of our institution. The variables analyzed were patients' age, gender, types and site of impaction, and complaints during reviews. Results: Overall, 115 patients with asymptomatic impacted mandibular third molars were seen, and 63/115 (54.8%) were treated. The age of the patients ranged from 26-65 years with a mean age of 42.3 ± 3.4 years. Majority (n=47, 74.6%) of the patients were in the age category of 31-50 years. The male: female ratio was 1: 1.3. Mesioangular (n=33, 52.4%) impaction was the most common. Complication rate was 4.8%, comprising two (3.2%) females and one (1.6%) male who had numbness of the ipsilateral lower lip. The numbness resolved by the 4th post-operative week, and the extraction sockets clinically healed uneventfully. Conclusion: This study shows that the complications associated with the surgical extractions of the asymptomatic impacted mandibular third molars were acute, neurological and without a permanent sequel.

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.
