Histopathologic Changes in Dental Follicle Associated With Radiographically Normal Impacted Lower Third Molars

Pathology Clinical Trial

Official title: Histopathologic Changes in Dental Follicle Associated With Radiographically Normal Impacted Lower Third Molars

Status Completed

Clinical Trial Summary

This study aimed to evaluate the incidence of histopathologic changes in dental follicles associated with radiographically normal impacted lower third molar and to determine the relationship between cystic changes in follicle tissues and age, gender, and the angular position of the impacted tooth.

Clinical Trial Description

Patients One hundred one healthy patients whose ILTM were extracted for various reasons in Tokat Gaziosmanpaşa University, Faculty of Dentistry, Department of Oral and Maxillofacial Surgery were included in the study. All participants included in the study signed an informed consent form. The study was conducted in accordance with the Declaration of Helsinki, and the protocol was approved by Tokat Gaziosmanpaşa University Clinical Research Ethics Committee for the study (Project number: 19-KAEK-081). The patients' panoramic radiographs were examined, and the impacted teeth were divided into four groups as vertical, horizontal, mesioangular, and distoangular according to their angular positions. The radiographically found that patients with a follicular width of less than 2.5 mm were included in the study. The follicular tissues were also excised after tooth extraction. Soft tissue samples taken during surgical removal of ILTM were evaluated in the department of pathology. Histopathological evaluation The excision materials obtained for the study were subjected to routine tissue follow-up procedures in Tokat Gaziosmanpaşa University, Faculty of Medicine, Pathology Department. The samples were fixed in 10% formalin solution for 24 hours for light microscope examination and blocked using the routine paraffin blocking method. The preparations were prepared by obtaining sections with microtome from the blocks. These preparations were stained with Hematoxylin Eosin and evaluated under a light microscope. In the histopathological examination, squamous epithelium, keratinization, odontogenic epithelial residue, and fibrosis were evaluated as either present or absent, and inflammation was scored as 0-absent, 1-mild, 2-moderate, or 3-severe. During the microscopic evaluation of follicular tissues, soft tissue samples with stratified squamous epithelium were identified as cystic. The relationship between histopathological changes observed in the radiographically normal dental follicles and gender and the teeth' angular positions was statistically evaluated. ;
