Effectiveness of fissure sealants on initial caries lesions (ICDAS 1-3) of permanent molars: A 4-year follow-up.

Aim: The aim of the present prospective study was to evaluate the retention and effectiveness of two types of sealants (clear vs. opaque) on early pit and fissure occlusal non-cavitated ICDAS II #1-3, caries lesions of permanent posterior teeth of children.

Materials And Methods: Study Design: 6986 pit and fissure occlusal surfaces were randomly sealed with clear or opaque sealants out of which, 5828 sealants were placed on sound and 1158 on questionable surfaces, while 3508 were clear and 3478 opaque sealants.

Caries prevalence of 5, 12 and 15-year-old Greek children: a national pathfinder survey.

Aim: To study the caries prevalence and caries experience of 5, 12 and 15-year-old children in Greece and evaluate how the disease pattern is related to their sociodemographic parameters.

Methods: A stratified cluster sample of 1209, 1224 and 1257 of five, twelve and fifteen-year-old Greek children were randomly selected according to WHO guidelines for national pathfinder surveys and examined for dental caries, according to the BASCD criteria and standards. d3mft, D3MFT and their components, as well as d3mfs, D3MFS, Care Index (CI) and SiC were recorded and related to the demographic data collected concerning age, gender, counties, urban/rural areas and parents' educational status.

Oral hygiene and periodontal status of 12 and 15-year-old Greek adolescents. A national pathfinder survey.

Aim: To investigate oral hygiene and periodontal status of 12- and 15-year old Greek adolescents, in relation to sociodemographic and behavioural parameters.

Methods: A stratified cluster sample of 1,224 12-year old and 1,257 15-year old adolescents of Greek nationality were selected and examined by calibrated examiners. Periodontal and oral hygiene status were assessed using the Community Periodontal Index (CPI) and the simplified Debris Index (DIs) respectively.

Socio-behavioural factors influencing oral health of 12 and 15 year old Greek adolescents. A national pathfinder survey.

Aim: To estimate the frequency in use of oral health services, oral health self-assessment, oral hygiene practices of 12- and 15-year-old Greek children and adolescents, to investigate possible influences of these factors and other socio-demographic parameters on oral health.

Methods: A stratified cluster sample of 1224 12 year old and 1257 15 year old children and adolescents of Greek nationality were selected and examined by calibrated examiners. Clinical examination included recording of caries according to the British association for the study of community dentistry diagnostic criteria, while oral hygiene and periodontal status were assessed by means of the simplified debris and the community periodontal index.

Cytokines in gingival crevicular fluid of adolescents and young adults.

Background/aim: The purpose of this study was to compare the levels of the cytokines interleukin-1beta (IL-1beta), IL-4, and IL-8 in the gingival crevicular fluid (GCF) of adolescents and young adults.

Methods: Twenty-five adolescents aged between 14 and 16 years (Group A) and 20 periodontally healthy young adults aged between 25 and 35 years (Group B) were selected from two private dental clinics limited to pedodontics and periodontics respectively in Piraeus Greece.
