Filter by:Decay is a multifactorial infective degenerative disease of hard dental tissues, caused by Streptococcus mutans and Lactobacillus forming the bacterial biofilm of teeth surfaces. Decays generally evolve in fissures and pits of secondary molars. Pits and fissure sealants prevent decays if performed in two years from eruption. Ozone has bactericidal effect and remineralizing capacity on enamel. The aim of this study is to assess the effectiveness of ozone application before sealants in increasing their duration in time.
The School of Dentistry is seeking to determine whether viable microorganisms remain within tooth structure after conventional, mechanical removal of areas of tooth decay, prior to placement or replacement of tooth restorations (fillings). The long-term goal of the work is to decrease the failure rate, and therefore increase the longevity, of tooth restorations (fillings) in human patients and populations.
The LENTO study sample includes the caregivers and their clients living in eastern Finland. The aims of this study are 1. to study the nutritional status, oral health, coping, functional capacity and quality of life 2. to find out how individual nutrition and oral health counseling received for caregivers affect on the nutritional status and oral health of caregivers and their clients 3. develop an operating model to maintain good nutrition and oral health.
The aim of the study was to compare dental caries treatment and follow-up based on an elaborate and individualized assessment of caries risk in children, to a simpler risk assessment strategy by means of a double-blind randomized clinical trial of two years monitoring. Participants will be children from 7 to 11 years old, who pass through the screening of the Children's Clinic of the Faculty of Dentistry of the Federal University of Pelotas and fulfill the inclusion criteria. A randomized, stratified sample of approximately 250 children will be included in the study, one group will be composed of children undergoing dental caries-related treatment and maintenance, guided by an individualized and multivariate risk assessment, and another group of children treated based on dental caries experience alone in the deciduous and / or permanent dentition. Recruitment will begin at the beginning of 2019, and participants will be followed up for 24 months. Parents will respond to an anamnesis, 24-hour dietary recall, food frequency questionnaire, and oral and general health-related quality of life questionnaire, children will undergo a clinical examination to assess caries, according to the International Caries Detection and Assessment System (ICDAS) in its simplified form and evaluation of caries activity. Dental treatments and return intervals will be designated according to the individual risk of the patient detected in the initial approach according to the group. The study evaluations consist of baseline, 12 months and 24 months, data will be transferred to spreadsheets after the different phases of the study. Primary outcomes (number of dental surfaces requiring operative intervention) and secondary outcomes will be analyzed by Student's t test, quality of life and quality of life related to oral health, will be assessed at the beginning of the study and at the end of treatment, and compared between the groups.
The primary goal of the study is to compare the success rates of pulpal anesthesia (defined as ability to complete the intended dental procedure without the need for rescue anesthesia) between Kovanaze nasal mist and Articaine needle anesthesia.
This study is comparing the effectiveness of two different dental crown fillings (resin crowns and zirconia crowns) for primary front teeth (incisors). Both dental crown fillings are currently used by community pediatric dentists. Resin crowns are currently the standard treatment for primary incisors at The Hospital for Sick Children (SickKids). Zirconia crowns are not presently used at SickKids. It is unknown if one type of crown is better than the other type. If the zirconia crowns produce similar or better results in fixing the primary front teeth, then the zirconia crowns may become the new standard of care at SickKids.
The purpose of this study is to evaluate and compare the clinical performance of Giomer and GIC restorations with and without SDF on caries sealing of primary molar teeth
Background There is little information regarding the longevity of the restored tooth, considering the health of the pulp-dentine complex, in children who do not sufficiently cooperate with dental treatment. Aim To evaluate the longevity of primary molar teeth with an occluso-proximal cavity that was treated with the selective removal of carious tissue. Design A total of 150 children were allocated to two parallel groups: group 1 (G1, n = 70, control, Ketac Molar Easymix®, 3M/ESPE, Seefeld, GE) and group 2 (G2, n = 80, test, Maxxion®, FGM, Joinville, BR). The study was double-blinded, and an operator specialized in paediatric dentistry performed the selective removal of soft dentine and the restoration of the cavity with GIC. During the follow-up periods, the teeth were evaluated via periapical radiography by two trained examiners specialized in radiology. Statistical analysis was performed using Stata 11.2 software (StataCorp, Texas, USA) and a survival curve (Kaplan-Meier).
This study will be conducted to evaluate the performance; in terms of retention and caries inhibition; of the newly introduced bioactive resin based pits and fissure sealant versus conventional resin based pits and fissure sealant in caries susceptible fissures in posterior molars in patients at risk of caries. Evaluation will be done by visual tactile examination & VistaCAM.
This research aimed to evaluate the risk of dental fluorosis by using an experimental fluoridated acidulated dentifrice compared to conventional dentifrices in two-to-four-year-old children residing in a non fluoridated area by the concentration of fluoride incorporated in childrens' nails, as well as the incorporation of F into the biofilm. Two hundred and ten children participated on this study. They were randomly allocated into three groups differing according to the type of dentifrice used over 12 months: G1:1100 ppm F, pH 4.5; G2:750 ppm F, pH 4.5; G3:1100 ppm F, pH 7.0. The dentifrice was placed on the toothbrush using the "drop" technique. The toenails of the biggest toe were collected in three moments, corresponding to the experimental period of use of the dentifrices (T1, T2 and T3), as well as the biofilm which was collected twice, 5 and 60 minutes after brushing. The nails and biofilm fluoride concentration were analyzed on a specific electrode using the HMDS diffusion facilitated technique.
