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)

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.

Facial Profile Characteristics Evaluation in a Population of Central Romania Region

Abstract

Objectives: The aim of the study was to evaluate the variables that define the facial profile of a sample of the population in the centre of Romania, and to compare male’s and female’s soft tissue profile. These values could be useful in elaborating the aesthetic objectives for treating the population in this area.

Material and methods: Fifty subjects were included in the study - patients and students of the University of Medicine and Pharmacy of Tîrgu Mureș (29 females and 21 males) between 18 to 28 years of age, having dental class I and a balanced profile. The photographs were taken in the natural head position (NHP). The anthropometric points were recorded and four of the angles that characterize a harmonious profile were traced and measured: the nasofrontal angle (G-N-Nd), the nasolabial angle (Cm-Sn-Ls), the mentolabial angle (Li-Sm-Pg), and the facial angle (G-Sn-Pg).

Results: The values obtained for the two sexes were compared using the t-student test. All angles had values that were larger for females (nasofrontal: females 137.1 degrees, males 135.79 degrees, p = 0.0019; nasolabial: females 105.3 degrees, males 102.19 degrees, p = 0.00002; mentolabial angle: females 126.07 degrees, males 118.27 degrees, p = 0.000009; facial angle: females 170.32 degrees, males 168.85 degrees, p = 0.0033).

Conclusions: Differences between the two sexes were obtained, all angles were statistically significant larger in females. These results show that for the population in the centre of Romania the treatment objectives are different for females and for males. The angular values range between those that characterize the Caucasian population.

Asymptomatic Double Aortic Arch Accidentally Diagnosed for a Child with T-Cell Lymphoma - Case Report

Abstract

Introduction. Double aortic arch (DAA) represents a vascular malformation generated by the persistence of the right dorsal aorta from the intrauterine life. An aortic ring is formed, that surrounds the trachea and esophagus, resulting in difficulty in breathing and swallowing.

Case report. We report the case of a 13 years old male child who was admitted to the pediatric surgery department accusing the presence of a paravertebral subcutaneous lesions. Histopathological result of the excised lesion revealed the presence of peripheral T-cell lymphoma. Examination of computer tomography angiography (Angio-CT) revealed the presence of a complete arterial chain (aortic double arch - DAA) around the trachea and esophagus, without signs of compression.

Most cases are diagnosed in the first year of life, the literature reports a few cases of DAA diagnosed late, to the adolescent or adult. Clinically most of the anatomical variants are usually symptomatic especially that are associated with congenital heart defects, including also Fallot tetralogy.

Conclusions. Angio-CT is a very useful method in diagnosing arterial or venous malformations, symptomatic or asymptomatic.
