Dental health and odontogenic infections among 6- to 16-year-old German students with special health care needs (SHCN).

Objectives: This cross-sectional study aimed to assess dental health and odontogenic infections in students with special health care needs (SHCN) in the Free State of Thuringia, Germany.

Methods: From 1283 students with SHCN aged 6-16 years, 66.0 % (n = 848 of whom are 35.

In vivo detection of non-cavitated caries lesions on occlusal surfaces by visual inspection and quantitative light-induced fluorescence.

Objective: The aim of this clinical caries detection study was to compare the outcome of quantitative light-induced fluorescence (QLF) and meticulous visual inspection (VI) in detecting non-cavitated caries lesions on occlusal surfaces in young adolescents. It was hypothesized that the respective diagnostic performances of meticulous VI and QLF are similar.

Material And Methods: The subjects were 34 fifteen-year-old students.

Establishing quantitative light-induced fluorescence cut-offs for the detection of occlusal dentine lesions.

The aims of this in vitro study were, first, to define suitable cut-off values for the detection of occlusal dentine lesions by means of quantitative light-induced fluorescence (QLF), and, second, to compare the validity of light microscopy (LM) and microradiography (MR) as reference standards. Fifty-four third molar occlusal fissures with sound sites or non-cavitated lesions were examined. Standard QLF equipment was used to capture, display, store, and analyze fluorescence images.

Detection of initial caries lesions on smooth surfaces by quantitative light-induced fluorescence and visual examination: an in vivo comparison.

The aim of this clinical study was to compare the outcome of quantitative laser/light-induced fluorescence (QLF) and visual inspection (VI) for the detection of initial caries lesions on all maxillary and mandibular smooth surfaces in caries-risk adolescents. The subjects were 34 students, mean age 15 yr. A total of 879 buccal and 882 lingual surfaces were air-dried and visually examined at a magnification of x3.
