Dental decay

Manuja Sharma, Matthew D Carson, Jasmine Y Graham, Leonard Y Nelson, Shwetak Patel, J Eric Seibel
Undetected caries can lead to painful cavities and surgical restorations. Lack of proper detection tools makes caries prevention dependent on dentist's expertise and presents obstacles in oral health monitoring. To overcome this problem, we have developed a new approach to predict early stages of enamel demineralization caused by oral bacteria. These bacteria metabolize sugars in our food and produce organic acids that lead to cavities. Measuring the acidity level can help predict early stages of tooth decay...

The prevalence of dissatisfaction with dental services and its association with normative and subjective oral health conditions among adult Brazilians was evaluated. This cross-sectional study used data from the last Brazilian National Oral Health Survey (SBBrasil), conducted in 2010. It was considered a representative sample of the adult Brazilian population. Data were analyzed by descriptive, univariate and multiple statistics (OR / 95% CI), with correction by the design effect. Among the 4539 adults included in the study, 614 (13...

The aim of this study was to evaluate the relationship between the perception of dental care services and oral health conditions in a hypertensive and diabetic population subscribed to the Family Health Strategy in the city of Alfenas, Minas Gerais, Brazil. This was a domiciliary, descriptive-analytical study with random and stratified sample, consisting of 186 individuals. The following indexes were applied: Decayed, Missing and Filled Teeth (DMFT); Filled and Sound Teeth (FS-T); Dental Care Index (DCI); Evaluation of the use and need of dentures; Oral health for primary care assessment questionnaire (OHPCA)...

OBJECTIVE: Dental caries is an important public health issue worldwide. In developing countries preventive dentistry is not common; hence, oral and dental health problems continue to generate serious economic and social issues. The aim of this study was to assess oral health and the incidence of dental caries in systemically healthy children aged 3-14 years, provide education on oral hygiene motivation, conduct the necessary preventive and restorative procedures, and reassess caries development at the 6-, 12-, and 18-month post-treatment follow-up...

Background: Successful management of dental fear in children prevents its progression into adulthood. This study aimed to assess the level of dental fear among school children and to determine its relationship with dental caries. The study design was a cross-sectional analytical study. Materials and Methods: A sample of 1,546 primary school children were randomly selected. The Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) was completed in class to assess child dental fear...

Objectives Elite athletes are at high risk for poor oral health. A screening program to assess oral health and create dental awareness can improve oral health among elite athletes but has not been performed in the Netherlands before. We summarize the first results from such a screening conducted in Dutch elite athletes of the Nederlands Olympisch Committee*Nederlandse Sport Federatie (NOC*NSF, Dutch Olympic Committee). Methods In this cross-sectional study, 800 Dutch athletes eligible for the Olympic and Paralympic Games in Rio de Janeiro 2016 were invited to a costless and voluntary oral examination...

The analysis of the distribution of stress in dental organs is a poorly studied area. That is why computational mechanobiological analysis at the tissue level using the finite element method is very useful to achieve a better understanding of the biomechanics and the behaviour of dental tissues in various pathologies. This knowledge will allow better diagnoses, customize treatment plans, and establish the basis for the development of better restoration materials. In the present work, through the use of high-fidelity biomodels, computational mechanobiological analyses were performed on four molar models affected with four different degrees of caries, which are subjected to masticatory forces...

BACKGROUND: In Vietnam, research is required to provide a clearer understanding of the factors associated with dental caries. This will allow paediatric dentists and physicians to provide appropriate care to children. AIM: To determine the factors related to dental caries and to evaluate the association between dental caries and nutritional status in 10-year-old schoolchildren. METHOD: In 2015, 1,079 10-year-old children were randomly selected from 16 public schools in Ho Chi Minh City...

Fluoride is one of the most abundant elements found in nature. Water is the major dietary source of fluoride. The only known association with low fluoride intake is the risk of dental caries. Initially, fluoride was considered beneficial when given systemically during tooth development, but later research has shown the importance and the advantages of its topical effects in the prevention or treatment of dental caries and tooth decay. Water fluoridation was once heralded as one of the best public health achievements in the twentieth century...

More than two-thirds of the global population suffers from tooth decay, which results in cavities with various levels of lesion severity. Clinical interventions to treat tooth decay range from simple coronal fillings to invasive root canal treatment. Pulp capping is the only available clinical option to maintain the pulp vitality in deep lesions, but irreversible pulp inflammation and re-infection are frequent outcomes for this treatment. When affected pulp involvement is beyond repair, the dentist has to perform endodontic therapy leaving the tooth non-vital and brittle...

INTRODUCTION: Oral health, the mirror of general well being, is altered by many mediators like infection, chronic inflammation, and genetic predisposition. Apart from these mediators, nutrition has been postulated as an alternative mediator. The present dietary pattern among children is contributing to childhood overweight as well as increasing the risk for developing dental caries. The food habits contributing to dental caries as well as obesity are similar. Undernutrition has also shown to be associated with the dental caries...

Thailand has a comparatively high prevalence of severe early childhood caries (S-ECC). S-ECC adversely affects the quality of life for children and their caregivers and represents a considerable economic burden. We have assessed the bacteriological composition of unstimulated saliva, dental plaque, and degraded dentine in a Thai cohort, including children with S-ECC and children without cavities; their siblings, and their primary caregivers. Samples were collected during a dental examination and patients were scored for plaque accumulation and their decayed, missing, and filled teeth (dmft) index...

BACKGROUND: Socioeconomic inequalities are associated with oral health status, either subjectively (self-rated oral health) or objectively (clinically-diagnosed dental diseases). The aim of this study is to compare the magnitude of socioeconomic inequality in oral health and dental disease among adults in Australia, Canada, New Zealand and the United States (US). METHODS: Nationally-representative survey examination data were used to calculate adjusted absolute differences (AD) in prevalence of untreated decay and fair/poor self-rated oral health (SROH) in income and education...

Resin-based composite has overtaken dental amalgam as the most popular material for direct restorative dentistry. In spite of this popularity the clinical lifetime of composite restorations is threatened by recurrent decay. Degradation of the adhesive leads to gaps at the composite/tooth interface-bacteria, bacterial by-products and fluids infiltrate the gaps leading to recurrent decay and composite restoration failure. The durability of resin-dentin bonds is a major problem. We address this problem by synthesizing silyl-functionalized BisGMA (e...

BACKGROUND: Health literacy has been found to be a strong predictor of an individuals' health, health behavior and health outcomes. Lower literacy has been linked to problems with the use of preventive services, delayed diagnoses of medical conditions, poor adherence to medical instructions, poor self-management skills, increased mortality risks, poor health outcomes, and higher health care costs. The aim of this study is to determine the relationship between oral health literacy (OHL) and oral health status among patients attending a University-affiliated dental clinic...
