ABSTRACT
Introduction: Impacted third molars are associated with various degrees of damage to the second molars. The possible complications also include distal cervical caries, root resorption of second molar, periodontal problems, odontogenic cysts, etc. Whether a particular impacted third molar is going to affect second molar depends upon its position and orientation in the bone. Materials and Method: This study was carried out in 418 cases. Three examiners evaluated the patient clinically and radiographically and only those cases were included in this study where at least two observers agreed. A total of 341 cases (163 males and 178 female), age range (15-40 years) with impacted mandibular third molars, were included. Clinically and radiographically, the impacted mandibular third and second molars were evaluated; simultaneously, the prevalence of various pathologies associated with mandibular second molar (dental caries, periodontal pockets, root resorption) due to impacted third molar was also evaluated and compared among various types and positions of impactions. Results: Statistical analysis was carried out using Pearson Chi-square and Asymp. Sig. (two-sided) test. Prevalence of mesioangular impactions was maximum (50.1%). Mesioangular impaction and position B (Pell and Gregory classification) were significantly associated with dental caries (32.20% and 33.90%, respectively), and periodontal pockets were seen higher with position B impactions (26.8%) {horizontal (14.7%), disto-angular (12.10%), vertical (14.5%) mesioangular (16.4%%)} in adjacent mandibular second molar. Root resorption was seen maximally in horizontal impaction (17.30%) with position c type (12.30%). The order of pathologies associated with second molar due to impacted third molar was dental caries (19.9%) > periodontal pockets (15.2%) > root resorption (8.5%). Discussion: Evidence regarding pathologies are associated with second molar due to impacted third molar aids in decision making for surgical removal of third molars. Different types of impaction and the prevalence of pathologies related to them would aid in treatment planning of the impacted tooth as certain types have high probability of pathologies associated.
ABSTRACT
Foreign body ingestion although unusual may be possible during dental treatment when placing any implants, prosthetic crowns, restoration, endodontic treatment, or orthodontic treatment. When the ingestion occurs, it is always crucial to locate the foreign body within the patient's body by taking bi-planar radiographs. Any features of airway distress or obstruction should be ruled out and if it is located in the gastrointestinal (GI) tract, the nature and size of the material will decide the protocol of retrieval of the ingested object. However, there is always a risk of intestinal perforations or obstructions secondary to the ingestion. Here is a case report wherein there was an accidental ingestion of the paralleling pin during the first stage of the implant placement with indications of various GI investigations and recommendations to avoid instrument ingestion.
ABSTRACT
BACKGROUND: Dimple is one of the special indentations in skin of the face, which is considered as a sign of beauty. Dimpleplasty/surgical creation of dimple is a cosmetic procedure done by surgeons. Determining accurate position of dimple to create maximum beauty is always challenging to surgeons. AIMS AND OBJECTIVES: This study aimed at evaluating the prevalence and morphology (position and size) of naturally occurring dimple among population of Sullia taluk. MATERIALS AND METHODS: In total, 1462 people were screened for the occurrence of natural dimples in face. Among them, 121 were found to have natural dimples. Prevalence of dimple, position of the dimple, and the variation in distance from the Khoo Boo-Chai's (KBC) point to the naturally occurring dimple was assessed. RESULTS: Among 121 patients with dimples, unilateral cheek dimples (72.88%) were more common than bilateral (27.11%). Ninety-one dimples (60.66%) were at KBC point and 59 dimples (39.33%) occurred anterior to KBC point at a mean distance of 9.86 mm. The mean size of dimple superoinferiorly on the right side was 8.29 mm and on the left side it was 8.96 mm. The mean size anteroposteriorly on the right side was 6.48 and on the left side it was 6.51 mm. CONCLUSION: The mean measurements in size and position of the dimple might help the surgeon in creating dimples resembling naturally occurring dimples.
