Current scoring systems for dental caries do not consider the dynamic nature of the disease. The aims of the present study were to describe a new set of clinical caries diagnostic criteria which differentiate between active and inactive caries lesions at both the cavitated and non-cavitated levels and to evaluate the reliability of this criteria system in a(More)
OBJECTIVES The aim of this 3-year community intervention trial was to determine the caries preventive effect of sugar-substituted chewing gum among Lithuanian school children, and to assess compliance with the instructions for gum use. METHODS A total of 602 children, aged 9-14 years, from 28 school classes in five secondary schools in Kaunas, Lithuania,(More)
It is now well-established that a linear relationship exists between fluoride dose and enamel fluorosis in human populations. With increasing severity, the subsurface enamel all along the tooth becomes increasingly porous (hypomineralized), and the lesion extends toward the inner enamel. In dentin, hypomineralization results in an enhancement of the(More)
This study reports the results of implant therapy involving a sinus membrane lift and of conventional implant therapy in 68 periodontally compromised patients treated between June 1990 and June 2002. Patients had at least two implants inserted, one of which was placed in the maxillary sinus region following fenestration of the lateral sinus wall and lifting(More)
The "checkerboard" Dna-Dna hybridization technology was used to study the epidemiology of 18 microbial species associated with various states of periodontal health and disease, in a sample of 148 Chinese subjects never exposed to systematic dental therapeutic intervention, aged 30 to 39 and 50 to 59 years. Our aims were to: 1) describe the prevalence of(More)
OBJECTIVES To investigate the association between periodontal disease parameters and coronary ischemic disease among 30-50-year-old Chileans. MATERIAL AND METHODS Cases were 30-50-year-olds who were hospitalized in one of four Cardiologic Units in Santiago, Chile, for acute myocardial infarction, unstable angina or angina pectoris. Controls had undergone(More)
BACKGROUND The systemic inflammation in both metabolic syndrome (MetS) and periodontitis is a common denominator of the association of these conditions with higher risk of atherosclerosis. The current study investigates whether periodontal therapy may reduce systemic inflammation in patients with MetS and reduce cardiovascular risk. METHODS A(More)
BACKGROUND Relatively little is known about the prevalence, severity, and determinants of clinical attachment loss among adolescents. METHODS A multi-stage random sampling procedure was used to obtain a sample of 9,203 high school students aged 12 to 21 years from the Province of Santiago, Chile. All but 41 students were examined for clinical attachment(More)
OBJECTIVE To demonstrate the usefulness of a survival-time regression model for the analysis of data from two 3-year trials of the caries-preventive effect of sugar-substituted chewing gums and fluoride toothpaste, carried out among 892 Lithuanian children. METHODS A caries onset was defined as a transition from sound to carious and a caries recovery was(More)
The need for treatment of destructive periodontal diseases is based on observations made by oral health professionals, who, prompted by clinical findings, recommend treatment. We hypothesized that clinical signs of periodontal destruction have an impact on the oral-health-related quality of life of adolescents. We conducted a cross-sectional study among(More)
