A Cross-Sectional Survey on Reasons for Initial Placement and Replacement of Single Crowns.

This cross-sectional survey investigated the reasons for placement and replacement of single crowns, the type of materials selected for initial placement and evaluated their longevity. Information was collected over 19 months period using a questionnaire focusing on the principal reasons for the placement and replacement of crowns, selected material type and the age of the crowns at the time of replacement. A total of 842 single crowns were evaluated in 476 patients.

A Survey on Prevalence, Causes and Prevention of Postcementation Hypersensitivity.

This study evaluated the prevalence and causes of post-cementation sensitivity and possible prevention measures according to the experience of dentists through an internet survey. A questionnaire was prepared with 25 items based on a survey introduced by Rosenstiel and Rashid. An online site was created for the participation to the survey.

Analysis of Endodontic Complications Following Fixed Prosthodontic Rehabilitation.

Purpose: The aim of this study was to determine endodontic treatment needs and types of endodontic disease following fixed prosthodontic treatment 24 hours after tooth preparation, 1 week after tooth preparation, 1 month after placement, and 6 months after placement.

Materials And Methods: Study groups consisted of patients who attended a university dental hospital department of prosthodontics for fixed prosthodontic treatment from January 2011 to December 2013. All teeth were clinically and radiographically evaluated according to American Association of Endodontists evaluation criteria before preparation.

Cement Thickness of Inlay Restorations Made of Lithium Disilicate, Polymer-Infiltrated Ceramic and Nano-Ceramic CAD/CAM Materials Evaluated Using 3D X-Ray Micro-Computed Tomography.

Purpose: To evaluate the marginal and internal cement thicknesses of inlay restorations made of various CAD/CAM materials using 3D X-ray micro-computed tomography (micro-CT) technique.

Materials And Methods: Caries-free extracted mandibular molars (N = 30) with similar size were randomly assigned to three groups (N = 10 per group). Mesio-occlusal-distal (MOD) cavities were prepared, and inlay restorations were obtained by milling out CAD/CAM materials namely, (a) IPS: monolithic lithium disilicate (control), (b) VE: polymer-infiltrated ceramic, and (c) CS: nano-ceramic using a CAM unit.

The effect of different adhesives and setting times on bond strength between Biodentine and composite.

Background: The aim of this study was to evaluate the effects of 3 different adhesives with different functional monomers, on the shear bond strength (SBS) of Biodentine®.

Methods: Acrylic blocks (n = 90) were prepared and a 2-mm height x 4-mm diameter hole was opened in each block. Every hole was completely restored with Biodentine®.

Radiographic evaluation of the prevalence of enamel pearls in a sample adult dental population.

Aim: Enamel pearls are a tooth anomaly that can act as contributing factors in the development of periodontal disease. Studies that have addressed the prevalence of enamel pearls in populations were scarce. The purpose of this study was to evaluate the prevalence of enamel pearls in the permanent dentition of Turkish dental patients by means of panoramic radiographs.

Incidence and distribution of pulp stones found in radiographic dental examination of adult Turkish dental patients.

Background: Pulp stones (PS) are discrete calcified masses found in the dental pulp, in the pulp tissue or become attached to or embedded into the dentine. The formation of pulp stones is still something of an enigma, leading to existence of some epidemiological gaps.

Aim: To determine the prevalence and distribution of pulp stones in posterior tooth group by using panoramic radiograph.

Investigation of prevalence and characteristics of mesiodens in a non-syndromic 11256 dental outpatients.

Aim: To investigate the prevalence of mesiodens in a sample of Turkish dental patients and their distribution among genders.

Patients And Methods: A retrospective study was performed using panoramic radiography of 11256 patients, who ranged in age from 15 to 55 years old. All data (age, sex and or syndrome) were obtained from the patient files and analyzed for mesiodens.

Unilateral fusion of mandibular permanent lateral incisor with canine: A report of a rare case.

Fusion is a developmental anomaly which occurs due to a union of one or more adjacent teeth during morpho-differentiation of the dental germs. Early diagnosis of this condition is important because it may cause clinical problems, such as esthetic concerns and arch asymmetry. These anomalies may be unilateral or bilateral and may affect either dentition, although the deciduous teeth are more commonly affected.

Prevalence of dentine hypersensitivity among university students in Turkey.

Background And Objective: Dentine hypersensitivity (DH) is a common clinical finding with a wide variation in prevalence values. There is lack of data on the prevalence of dentinal sensitivity in Turkish population. The aim of this study was to establish the prevalence of DH and to examine some associated factors such as initiating stimuli among university students in Kırıkkale, Turkey.

Prevalence of dentine hypersensitivity among adult patients attending a dental hospital clinic in Turkey.

Objectives: The aim of this study is to determine the prevalence of dentine hypersensitivity (DH) and to examine some associated factors such as the initiating stimuli among adult patients attending the Restorative Clinic of the Kirikkale University Dental Faculty, Turkey.

Methods: Questionnaires for 1169 patients, 678 men and 491 women, were completed and necessary clinical examinations performed during a one-year period and patients who were diagnosed with DH were questioned further about their occupation and smoking habits. Patients with at least two different quadrants which had sensitive teeth with sound exposed cervical dentine on the facial surface, were included in the study.

Radiographic study of the prevalence of dens invaginatus in a sample set of Turkish dental patients.

Aim: The aim of this study was to determine the prevalence of dens invaginatus in a sample of Turkish dental patients.

Materials And Methods: The sample included 6, 912 panoramic radiographs from different Turkish dental patients. The ages of the patients ranged from 18 to 50 years.

An analysis of the aetiology, prevalence and clinical features of dentine hypersensitivity in a general dental population.

Aim: Dentine hypersensitivity may be defined as pain arising from exposed dentine typically in response to chemical, thermal or osmotic stimuli that cannot be explained as a rising from any other form of dental defect or pathology. The aim to this cross-sectional study was to determine prevalence of dentine hypersensitivity (DH) and to examine some associated etiological factors in a study of patients visiting general dental practitioners in Turkey.

Patients And Methods: A total of 1368 patients were examined for the presence of cervical dentine hypersensitivity by means of a questionnaire and intraoral tests by (air and probe stimuli).

Assessment of the prevalence of pulp stones in a sample of Turkish Central Anatolian population.

Objective: The aim of this study was to determine the prevalence of pulp stones (PS) in a Turkish dental patient population with respect to sexes and dental localization in relation between sex and this anomaly.

Materials Methods: A retrospective study was performed using bitewing radiographs of 814 patients ranging in age from 15 to 65. All data (age, sex, and location) was obtained from the files.
