Filter by:The aim of the present study is to provide a new domiciliary oral care treatment for enamel remineralization in rugby players patients using mouthguards. Patients selected for the study will be randomly divided and allocated in two groups according to the treatment: - Group 1: scaling and root planing (SRP) + Biorepair Total Protective Repair toothpaste for home oral hygiene twice a day - Group 2: scaling and root planing (SRP) + Biorepair Total Protective Repair toothpaste + Biorepair mouthwash (3 in 1) for home oral hygiene twice a day Patients will be given instructions for the cleaning of their mouthguards. The periodontal evaluation will be conducted before SRP, after 15, 30 and 90 days. The periodontal indices collected will be: PI, BoP, Schiff Air Index, BEWE index and dental sensitivity (VAS scale).
Study to determine if whether or not exist an association between the tissue loss (ETW progression) and the frequency of an acidic diet. To accomplish the aim, a quantitative analysis of intraoral scans of study models will be performed to identify erosive tooth wear progression in a group of Chilean adolescents. First, participants with different intake of dietary acids will be compared in terms of their baseline sociodemographic and clinical characteristics. Second, the association between baseline frequency of dietary acids and changes in volume loss over time will be evaluated using linear mixed models to account for the data structure (repeated assessments nested within teeth and teeth nested within children). Models will be adjusted for demographic factors, family socioeconomic position, health behaviours and chronic conditions.
The aim of this study is to investigate whether smoking is associated with changes in salivary composition and/or predisposition to erosion. Healthy volunteers are observationally wearing an intraoral device with both bovine tooth specimens (enamel and dentin) and resin specimens twice for two hours each. Afterwards, specimens are eroded extraorally and calcium release into the acid is measured. Total protein concentration and protein composition of the salivary pellicles on the resin samples are measured. Additionally, salivary parameters (unstimulated and stimulated saliva flow rate, pH, buffer capacity, total protein content and protein composition as well as concentration of inorganic calcium, phosphate, and fluoride) are measured.
Non-carious cervical lesions are defined as loss of pathological material not associated with caries in the enamel-cement junction of the tooth. The etiology of these lesions has been defined as brush abrasion, acid-induced erosion and abstraction due to microstructure losses due to stress concentration in a particular region of the tooth. These lesions should be restored using minimally invasive techniques. The necessity of restorative treatment is directly related to the size of the lesion, sensitivity and aesthetic requirements. However, restorative procedures are often challenging because the cavity preparation does not provide adequate retention, and often the cervical end margin is positioned under the gingiva. This leads to contamination of the operation site with blood, saliva and gingival fluid. Several restorative options have been proposed for the treatment of cervical caries-free lesions. However, due to their high aesthetic properties, improved adhesive capacity and mechanical properties, composites have been accepted as the most suitable choice. Clinical studies have demonstrated that marginal adaptation, marginal discoloration, and roughening methods for retention are the most important factors in the clinical performances of composite restorations in cervical lesions. Therefore, injectable composites with wettability and better adaptability to cavity margins have been introduced. However, the low filler contents of fluid composites and their weak mechanical properties compared to conventional composites have led researchers to doubt their use in caries-free cervical lesions. As a result of the developed material technology, injectable composites with high filler which have reduced polymerization shrinkage have been developed with simplified filler procedure. However, investigators have not encountered any studies investigating which etching technique this material will exhibit better clinical performance and comparing it with traditional pasty composites. The aim of this study is to evaluate the clinical performance of traditional paste type and injectable composites which will be made by using two different etching techniques.
40 specimens were prepared from fresh-extracted human molars and further embedded using the acrylic resin. Specimens were randomly divided into 2 groups according to the treatment before in vivo erosion (n=20): CPP-ACP for 3 min (CPP-ACP group) and deionized water for 3 min (control group). 10 healthy volunteers were recruited and customized maxillary appliance containing 4 specimens (2 from CPP-ACP group and 2 from control group) was fabricated for each volunteer. Participants were instructed to drink 150 ml cola in 5 min using the gargling method after placing appliances intraorally for 2 h. The in vivo attacks were performed 4 X 5 min with 1-h interval daily over 7 d. The surface microhardness and surface microstructure of the specimens were evaluated at the baseline and after the treatment. The data were statistically analyzed using three-way ANOVA and post hoc tests. Data were considered statistically significant at a level of P <0.05.
Background: Children with congenital heart defects (CHD) are reported to have poorer oral health compared with healthy children. The aim of the present study was to evaluate the effect of an intensive oral health care program among children with CHD followed from infancy to the age of five years, by comparing their oral health status at five years with a control group of children with CHD who had not received the program. Methods: In this longitudinal study, children in western Norway with a need for lifelong follow-up due to congenital heart defects were invited to participate (n=119). Children born in 2008-2011 were offered a promotive oral health intervention program from infancy to the age of five years. The outcome measures for evaluating the intervention were dental caries prevalence, dental erosion, plaque index and gingival bleeding index. The data of the intervention group were compared with cross sectional oral health data of five year old controls with CHD born 2005-2007 (already published).
Healthy volunteers are observationally wearing an intraoral device with bovine tooth samples once for two hours. Afterwards, Calcium release from the bovine enamel and dentin samples is measured after extraoral erosion. Total protein concentration within the formed salivary pellicles on the bovine samples is determined. Further Salivary parameters (unstimulated and stimulated saliva flow rate, pH, buffer capacity, albumin and total protein content as well as concentration of inorganic calcium, phosphate and fluoride) are being measured. The aim of this study is to investigate whether gender differences in the salivary composition correlate with predisposition to erosion.
The purpose of this study is to compare and evaluate the ability of two European Union (EU) regulated gel to foam toothpaste formulations versus a non-fluoride toothpaste using a modified in-situ model of dental erosion and remineralization. A positive control i.e fluoride containing toothpaste marketed in EU will also be compared to non-fluoride toothpaste.
This study investigates the prevalence and pathophysiology of dental and periodontal involvement in pediatric patients with symptomatic or asymptomatic gastroesophageal reflux (GER) or gastroesophageal reflux disease (GERD). Primary objectives are to compare the prevalence of oral disease in children with and without a diagnosis or symptoms/signs of GERD in a cross-sectional study. Secondary objectives are to examine factors that might lead to the pathogenesis of the dental and periodontal lesions observed in this group of subjects. The primary hypothesis is to prove that children aged 10-18 years diagnosed with or having symptoms or signs of GERD have a significantly higher amount of dental erosions in comparison to a matched control group. Secondary hypotheses are that children aged 10 - 18 years diagnosed with or having signs of GER have higher DMFS (Decayed, Missing, Filled permanent tooth Surfaces) rates, higher SBI (Sulcus Bleeding Index) rates, worse Periodontal status, and lower saliva buffering capacity.
The purpose of this study is to determine whether an experimental fluoridated dentifrice is effective in the treatment of dental caries
