Dental Caries Prevalence and Experience (ICDAS II Criteria) of 5-, 12- and 15-Year-Old Children and Adolescents with an Immigrant Background in Greece, Compared with the Host Population: A Cross-Sectional Study.

Evidence regarding disparities in oral health among native and immigrant child and adolescent populations in Europe is scarce. The present study aimed to determine the caries status of 5-, 12-, and 15-year-olds with an immigrant background in Greece in relation to their sociodemographic characteristics and compare their caries levels with those of their native Greek peers. A sample of 707 immigrants underwent clinical examination for caries (ICDAS II criteria), followed by a calculation of caries prevalence and experience estimates (2013-2014).

Socio-behavioral factors, oral hygiene level and periodontitis prevalence in a 35-44-year-old Greek adult population: A cross-sectional survey.

Background: Sub-optimal oral hygiene is considered as a primary risk factor for periodontitis occurrence. Various socio-behavioral determinants may contribute either independently or by influencing adversely the oral hygiene (OH) level. The aim of the present study was to examine the periodontal status of 35-44-year-old Greek adults and determine the contribution of risk indicators, including the socio-behavioral aspects and the population's oral hygiene level, on disease prevalence.

Caries prevalence and caries experience (ICDAS II criteria) of 5-, 12- and 15-year-old Greek children in relation to socio-demographic risk indicators. Trends at the national level in a period of a decade.

Purpose: To study the caries status of 5, 12 and 15-year-old Greek children, assess how disease parameters are related to socio-demographic indicators and identify relevant trends at the national level.

Methods: A stratified cluster sample of 3702 children in total was randomly selected and examined clinically for caries (ICDAS II criteria). Caries experience was outlined by adapting ICDAS criteria to the d/D component of the WHO dmf/DMF index configuration.

Effect of toothpastes containing different NaF concentrations or a SnF2/NaF combination on root dentine erosive lesions, .

Background: Fluoride toothpastes presumably offer some protection against acid erosion. However, uncertainty exists towards fluoride's efficacy relatively to the concentration and the type of chemical compound used. This study evaluated the relative efficacy of toothpastes containing sodium fluoride in different concentrations or a stabilized stannous fluoride/sodium fluoride system on root dentine erosion.

An in vitro study of the effect of aluminum and the combined effect of strontium, aluminum, and fluoride elements on early enamel carious lesions.

The purpose of this in vitro study was to evaluate the effect of aluminum and of combined strontium, aluminum, and fluoride treatments on enamel demineralization and remineralization. During a 6-day pH-cycling protocol, pre-softened bovine enamel slabs were immersed twice daily for 1 min in the following experimental solutions: (a) distilled water [W] (negative control); (b) 1,000 ppm F [F] (positive control); (c) 1,000 ppm Al [Al]; (d) 1,000 ppm Al,1,000 ppm F applied interchangeably [Al-F]; (e) 1,000 ppm Al, 1,000 ppm F, applied in sequential order [Al+F]; (f) combined 1,000 ppm Al and 150 ppm Sr [Al+Sr]; and (g) combined 150 ppm Sr and 1,000 ppm F [Sr+F]. Subsequently, the specimens were subjected to a 5-day acid resistance test.

In vitro evaluation of fluoride and calcium sodium phosphosilicate toothpastes, on root dentine caries lesions.

Objectives: The aim of this in vitro study was to assess the effect of toothpastes containing three different sodium fluoride concentrations and a calcium sodium phosphosilicate system, on root dentine demineralization and remineralization.

Methods: During a fourteen-day pH-cycling protocol, pre-softened bovine root dentine specimens were immersed twice daily, before and after the demineralization periods, for 2 min, in the following toothpaste slurries: (a) non-fluoridated (control), (b) 7.5% calcium sodium phosphosilicate, (c) 1450 ppm F, (d) 2800 ppm F, and (e) 5000 ppm F.
