Clinical and Statistical Study on Canine Impaction

Abstract

Aim: The aim of this study was to perform a clinical and statistical research on permanent impacted canine patients among those with dental impaction referred to and treated at the Oral and Maxillo-Facial Surgery Clinic of Tîrgu Mureș, over a four years period (2009-2012). Materials and methods: The study included 858 patients having dental impaction, and upon clinical records, different parameters, like frequency, gender, age, quadrant involvement, patient residence, associated complications, referring specialist and type of treatment, related to canine impaction, were assessed. Results: The study revealed: about 10% frequency of canine impaction among dental impactions; more frequent in women, in the first quadrant (tooth 13); most cases diagnosed between the age of 10-19 years; patients under 20 were referred by an orthodontist, those over 20 by a dentist; surgical exposure was more often performed than odontectomy. Conclusions: Canine impaction is the second-most frequent dental impaction in dental arch after third molars; it occurs especially in women. Due to its important role, canine recovery within dental arch is a goal to be achieved, whenever possible. Therefore, diagnose and treatment of canine impaction requires an interdisciplinary approach (surgical and orthodontic)

Immunoexpression of Ki67 and p53 in the Dental Follicles of Impacted Teeth

Abstract

Aim. The purpose of this study was to evaluate the morphological aspects of dental follicles associated with impacted teeth and the immunoexpression of Ki 67 and p53, in the remaining epithelium from impacted third molars and canines. Another aspect was to identify the transformation of the remaining epithelium within the odontogenic lesions.

Material and method. We included in the study a number of 100 dental follicles, of which only 62 met the inclusion criteria. The immunohistochemical reactions were carried out in the Immunohistochemistry Lab at the Department of Histology of the University of Medicine and Pharmacy of Târgu Mureş. We counted 100 cells from the remaining epithelial islands from which we determined the percentage of labeled cells for both markers. After this all data were subjected to a statistical analysis.

Results. Out of the 62 specimens 44 were from females and 28 from males. Positive results were obtained for the two markers but not for all cases. We have also found a positive correlation regarding the immunolabeling of the two markers (p=0.002 in canines, p=0.0001 in molars). Median values for ki67 were statistically significantly higher than the values for p53 for both types of dental follicles.

Conclusions. Both markers were expressed in the remaining epithelial islands. The stronger expression of Ki67 in the follicles of impacted molars can demonstrate the higher frequency of odontogenic cysts in this area.

A Retrospective Longitudinal Study Regarding The Dental Anomalies Of Position With Eruptive Etiology

Abstract

Objective: Given the high frequency of dental anomalies of position and the lack of preventive measures of surveillance and monitoring of the eruption of permanent teeth, the aim of this study is to evaluate the frequency of dental anomalies of position in children.

Material and methods: We conducted a retrospective longitudinal study in the 2006-2012 period. Data were collected from the medical records and orthopantomography x-rays of 408 patients (230 female and 178 male) who presented to the Pedodontics-Orthodontics Clinic in Tîrgu Mureș. After applying the exclusion criteria, 77 patients remained in the study.

Results: From the 77 patients, 57 had dental inclusions, 15 presented ectopic teeth, dental rotations have been observed in 2 patients, and midline diastema in 5 patients. Regarding sex distribution, there was a higher frequency of dental inclusions in women (39) than men (38). The frequency of dental inclusions, regarding dental groups, in a descending order was: maxillary canine, mandibular second premolar, mandibular canine, maxillary second premolar, mandibular first premolar, maxillary first premolar, maxillary lateral incisor, maxillary central incisor and maxillary and mandibular first molars. The frequency of dental inclusions in the dental support area had the highest rate in the 12-14 years age group.

Conclusions: From all the studied dental anomalies, dental inclusions presented the highest frequency. Regarding the dental support area, most cases of dental inclusion were observed in the 12-14 years age group.
