The prevalence of root dilacerations in a Turkish population

Objectives: The aim of this study was to determine the prevalence of root dilaceration in a Turkish dental patient population with respect to sexes and dental localization in relation between sex and this anomaly. Study Design: A retrospective study was performed using periapical radiography of 2,124 patients ranging in age from 15 to 65. All data (age, sex and systemic disease or syndrome) was obtained from the files. These patients were analyzed for root dilaceration. Descriptive characteristics of sexes, jaws, and dental localization were recorded. The Pearson chi-squared test was used. Results: Of 2,251 patients, 214 (9.5%) had root dilaceration. Root dilacerations were determined in 276 (4.3%) of 6386 teeth belong to 2251 patients. Anomalies were found in 9.8% of males compared with 9.3% of females. However, this difference was not statistically significant (p>0.05). Root dilacerations were similarly distributed between maxilla and mandible. The most frequently root dilacerated teeth were found to be mandibular third molars (12.8%), followed by maxillary third molars (7.4%), maxillary first molars (6.7%). Root dilaceration was not detected in maxillary central incisors, mandibular central incisors and mandibular lateral incisors. Conclusion: According to our results, root dilaceration is an uncommon developmental anomaly which mostly occurs in the posterior teeth that is not also possible to have trauma. The radiographic diagnosis of this anomaly is important before surgery and orthodontics treatment, but firstly endodontic treatment

Construction of new chaotic dynamical systems on a 2D Cantor set

In this paper, we construct new discrete chaotic dynamical systems on a 2D Cantor set by using the shift map, a 0-preadded map and a 2-preadded map. We also obtain a collection of chaotic dynamical systems using the elements of the symmetry group of the square

Bilateral bifid mandibular canal: a case report

The objective of this case report is to help clinicians identify bifid mandibular canals on panoramic radiographs and subsequently use the information in the modification of dental treatment planning. A 45-year old man was referred to the service of Oral Diagnosis and Radiology. Routine panoramic radiography, suggested the presence of bilateral bifid mandibular canals (BMC). Mandibular computed tomography revealed a clear view of bilateral mandibular canals. BMC can be detected on a panoramic radiograph

Morphology of spermathecae of some pentatomids (Hemiptera: Heteroptera: Pentatomidae) from Turkey

WOS: 000352096800004PubMed ID: 25947482The spermathecal morphology of nine species belonging to the Pentatomidae (Insecta: Heteroptera) were compared by optical and scanning electron microscopy (SEM). Among the examined species [Rhaphigaster nebulosa (Poda 1761), Palomena prasina (Linnaeus 1761), Piezodorus lituratus (Fabricius 1794), Graphosoma lineatum (Linnaeus 1758), Graphosoma semipunctatum (Fabricius 1775), Aelia albovittata (Fieber 1868), Codophila varia (Fabricius 1787), Ancyrosoma leucogrammes (Gmelin 1790), Nezara viridula (Linnaeus 1758)], all spermathecae contained a spermathecal bulb (reservoir), a pumping region, distal and proximal flanges, proximal and distal spermathecal ducts, dilation of spermathecal duct and a genital chamber containing two ring sclerites, but each species had a different spermathecal morphology.Gazi University (Turkey)Gazi University [05/2006-24]We wish to acknowledge Dr. Robert Lavigne (Professor Emeritus, University of Wyoming, Laramie, Wyoming, U.S.A.) for linguistic improvement and for the incisive review of the manuscript.

Correlation between oral health-related quality of life (OHQoL) and oral disorders in a Turkish patient population

Objectives: The purpose of the present study is to determine the nature of the complaints that bring patients to our clinic and to what degree these complaints affect their quality of life (QoL). We also aimed to determine any associations between gender, education or harmful habits and each patient?s oral health-related quality of life (OHQoL). Methods: A total of 1090 patients, consisting of 651 females (59.7 %) and 439 males (40.3 %), were included in this study. Of these patients, 220 constituted healthy controls. Two patient-centered outcome measures, the 14 item OHIP-14 and the 16 item OHQoL-UK measures were used. Results: Most of the patients presented with toothache and caries (50.1 %), 11.2 % had suffered tooth loss and had denture needs, 9.2 % had periodontal problems, 1.8 % had temporomandibular joint (TMJ) disorders, 3.8 % had buried third molars, 2.4 % had orthodontic and aesthetic disorders, 1.3 % had suffered injury due to trauma, and 20.2 % came only for control checkups. OHQoL was best in the control group and the worst in patients who had suffered trauma. In addition, we noted correlations between gender, education and harmful habits, and that of the patient?s oral health-related quality of life. Conclusion: According to our results, OHQoL is associated with the oral complaints of patients. Furthermore, OHQoL may not only be associated with the oral health status of patients, but factors such as gender, education and harmful habits may also play a role
