RATIONALE Dental caries is a global public health problem, especially in children. Most caries in developing countries remains untreated. Only limited data are available on the clinical consequences of untreated dental caries because there is no measure to quantify the prevalence and severity of oral conditions resulting from untreated dental caries.

This study tested recently recommended cut-off limits for the laser fluorescence based device DIAGNOdent (KaVo) for detection of occlusal caries. Two hundred and forty-eight permanent molars from 94 patients (mean age 19.2 years) of a general dental practice were included. After professional tooth cleaning, the teeth were examined visually and by the laser(More)
The aim of this clinical study was to test cut-offs for occlusal caries detection by the laser fluorescence device DIAGNOdent (DD) in comparison to visual-ranked inspection (VI) and bitewing radiographs (BW) under condition of a general dental practice. 281 occlusal surfaces of permanent molars from 97 patients were examined with VI, DD and BW. Caries(More)
BACKGROUND Dental decay is the most common childhood disease worldwide and most of the decay remains untreated. In the Philippines caries levels are among the highest in the South East Asian region. Elementary school children suffer from high prevalence of stunting and underweight.The present study aimed to investigate the association between untreated(More)
OBJECTIVE This meta-analysis investigates the clinical retention of pit and fissure sealants in relation to observation time and material type. DATA, SOURCES AND STUDY SELECTION A search in the MEDLINE, EMBASE and CENTRAL databases identified 2944 abstracts (published prior to 9/30/2011), of which 485 clinical publications were analyzed in detail. A total(More)
OBJECTIVE This epidemiological study aimed to assess the proportion and extent of manifestation of enamel hypomineralization, including molar-incisor-hypomineralization (MIH), in the permanent and primary dentition. METHODS A total of 693 children enrolled in an ongoing birth cohort study (GINIplus-10) were examined at their 10-year follow-up. Enamel(More)
The aim of this clinical-morphological study was to investigate the effects of dental probing on occlusal surfaces by scanning electron microscopy (SEM). Twenty sound occlusal surfaces of third molars and 20 teeth with initial carious lesions of 17- to 26-year-old patients (n = 18) were involved. Ten molars of each group were probed with a sharp dental(More)
Given the limitations of adjunct caries detection and diagnostic tools, e.g., imperfect validity and reproducibility, as well as the difficulties in controlling all possible confounding factors, the need for an objective visual caries detection and diagnosis system has become evident. Our work has therefore aimed at systematizing caries lesions with the(More)
Because of different measurement techniques and the easier design of the CRM prototype, this in vitro study aimed to compare the diagnostic performance and reproducibility of two electrical methods (Electronic Caries Monitor III, ECM and Cariometer 800, CRM) for occlusal caries detection, and to evaluate the effect of staining/discoloration of fissures on(More)
This paper on quantitative light-induced fluorescence (QLF) covers the main developments, physical principles, and current application areas of this noninvasive optical method for caries detection. Until now, QLF has mainly been used to detect and monitor initial carious lesions on smooth surfaces, whereas few studies have tried to assess its performance on(More)
