Filter by:This study will evaluate and compare the effect of the amount of toothpaste used and brushing time on enamel strengthening (percent of surface microhardness recovery, % SMHR) and enamel fluoride uptake (EFU).
The purpose of this study is to extend our knowledge concerning the clinical performance of two dental filling materials in molars. The study will compare two high-strength glass-ionomer filling materials. The investigators hypothesize that after two years (1) the clinical performance of both filling materials shows a similar survival rate, (2) the ChemFil Rock fillings show similar or higher incidence of fracture than Fuji IX GP fillings.
The proposed test is intended to enable dentists to differentiate between cavitated and non-cavitated tooth decay in the areas where teeth are in contact (interproximal surfaces). In these areas, dentists cannot visually inspect for caries, and currently bitewing X-rays (BWs) only correctly detect the presence of enamel decay 15-25% of the time. This low sensitivity can lead to late treatment resulting in unnecessarily large fillings, crowns, pain, root canals, and possible later loss of teeth. Hypothesis: Use of radiographic contrast on teeth will increase the accuracy of detection of early cavitation from 58% to 90%.
Objective: The aim of this study is to assess the effectiveness of an oral health educative intervention in preventing early childhood caries (ECC). Methods: The trial targets 0- to 12-month-old children and their mothers in Pelotas, Brazil. Twenty-four public health centres (clusters) were randomly selected and assigned to intervention or control group (12 clusters per intervention group). In each center, up to 30 children/mothers were selected and invited to participate in the trial. Each mother was interviewed in order to collect socio-economic and demographic variables. The intervention group received by means of a pamphlet the oral health instructions, which were emphasized with verbal instructions. Dental examination will be carried out after 1 year for all teeth surfaces to determine caries status.
Study will look at ability of fluoride varnish to remineralize white spot enamel lesions that can occur around the edge of fixed orthodontic brackets.
This study is investigating the efficacy of caries lesion infiltration therapy as compared to the current preventative approach for early caries lesions.
The Composites and Urinary Bisphenol-A Study (CUBS) is a clinical study of dental composite for its effects on urinary bisphenol-A levels. The study will enroll approximately 139 children recruited from study-affiliated clinical sites in New England.The primary aim of CUBS is to test the hypothesis that urinary bisphenol-A (BPA) concentrations increase after composite restoration placement. BPA is a chemical used in the synthesis of matrix monomers and has been shown to have harmful effects in toxicological studies in laboratory animals. Currently it is unknown whether dental composite restorative materials containing monomers that are derived from BPA result in chronic low-dose BPA exposure in children.
Aim: to determine the optimal Ca2+ concentration with 905 ppm F as NaF. Study design: Experimental study in 10 volunteers. Single blind mouth rinse with calcium lactate solution (150; 75; 0 mM Ca-lactate) is immediately followed by a standard fluoride rinse. Procedure: Rinses are performed in the evening. The rinse combinations are given in a random order, and the subjects are unaware of the sequence. At least 3 days separates the use of each rinse. Dosage: 20 mL and 1 minute rinse with each solution. Saliva samples: Twelve hours after rinsing, unstimulated saliva samples are collected by expectoration. Analysis: The fluoride concentration in saliva samples are analysed Statistics and data handling: Fluoride in saliva 12 hours after rinsing are examined by one-way ANOVA, repeated measures design.
Mutans streptococci (MS) and lactobacillus species (LB) are the two groups of infectious cariogenic (caries-causing) bacteria most strongly associated with dental caries (dental decay). Infants acquire cariogenic bacteria from their mothers early in development via saliva. There have been several studies that have demonstrated a significant reduction in dental caries associated with consumption of the food additive known as xylitol in children and adults. Xylitol is a non-toxic 5 carbon polyol, approved as a food additive by the FDA, that tastes like and behaves like sucrose in humans. Xylitol is used as a sugar substitute to reduce dental caries as it is not fermentable by the caries causing bacteria. In addition, an observed positive beneficial side effect of this sugar substitute is that xylitol has been shown to reduce mother to child bacterial transfer when used by the mother. It is commonly recommended to wipe infants' teeth and gums with a soft cloth to reduce the formation of dental bacterial plaque. Recently wipes have been marketed that contain xylitol to provide a safe sweet sensation for the infant during this cleaning procedure. However, no study has been conducted that assesses the biological effect of applying xylitol directly to the teeth and gums of infants. This study will be conducted to test whether xylitol applied by swab directly to the infant's teeth and gums will effectively reduce bacterial transfer from mother to child. Children age up to two years old whose mothers have high cariogenic bacterial counts will be recruited to use xylitol wipes 3-4 times daily in addition to their normal preventive regimen. This will be a randomized double blinded study where the control group will receive placebo wipes (with no xylitol) and the experimental group will receive the xylitol wipes. The mother-child pair MS and LB bacterial counts and caries score of the children will be measured at baseline, 3 months, 6 months and 1 year. We will contact all patients that were recruited into the study to inquire whether they are willing to return for further follow-up visits at 1, 2, 3, and 4 years post-wipe treatment completion. If successful, this study will support the use of a simple caries preventive measure that could be easily and safely implemented in young children. Ten MS isolates and unique LB colonies will be isolated from each saliva samples to study their genetic diversities and virulence factors. The investigators will also investigate whether specific MS genes relate to ECC prevention effect of daily xylitol-wipe application using genomic sequencing of MS isolated from current study when the active intervention was applied.
The aim of the present study are to determine whether there is an association between respiratory problems and dental caries in children who exhibit the habit of bruxism.
