Prevalence of caries among preschool-aged children in a central Anatolian population.

Objective: Early childhood caries (ECC) is a particularly destructive form of tooth decay that afflicts young children. The etiology and associated factors of ECC should be studied adequately to overcome this health hazard. The aim of this study was to determine caries prevalence and its consequences in toddlers in an Anatolian city, Kırıkkale.

One-year clinical evaluation of Quixfil and Gradia Direct composite restorative materials in posterior teeth.

Objective: The purpose of this study was to evaluate and compare the 12 month clinical performances of two different posterior composites in Class I and Class II restorations.

Methods: Class I and class II cavities of 62 patients, 74 Quixfil (Dentsply/ Xeno V) and 68 Gradia Direct (GC America/G bond) composite restorations were placed by two dentists. Only small and medium-sized cavities were included in the study.

Taurodontism in a central anatolian population.

The aim of this retrospective study was to evaluate the frequency of the occurrence of taurodontism in a Turkish population with using panoromic radiographs. A retrospective study was performed using full-mouth periapical and panoramic radiographs of 6912 patients (3860 females and 3052 males) ranging in age from 15 to 50. A total of 97362 posterior (including third molars) were evaluated.

Human immunodeficiency virus/acquired immunodeficiency syndrome knowledge among high school students in Kırıkkale province of Turkey.

Background: The purpose of the present study was to assess the existing level of knowledge of high school children about human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and the sources of their information.

Materials And Methods: A cross-sectional survey was conducted in two high schools in Kirikkale, Turkey and data were collected by a self-administered questionnaire. Multi-stage sampling technique was used to obtain a representative sample.

Early childhood caries update: A review of causes, diagnoses, and treatments.

Dental caries (decay) is an international public health challenge, especially amongst young children. Early childhood caries (ECC) is a serious public health problem in both developing and industrialized countries.
