Filter by:Management of deep carious lesions in permanent mature molars with reversible pulpitis represents a challenge for clinicians. Vital pulp therapy includes indirect and direct pulp capping, partial pulpotomy and full pulpotomy. Indirect pulp capping is a procedure in which a material is placed on a thin layer of remaining soft dentin that, if removed, might expose the pulp. The objective is dentin bridge formation and pulp vitality preservation. The aim of this randomized clinical trial is to evaluate the success rate of indirect pulp capping with Biodentine and TheraCal LC in mature permanent molars with deep carious lesions at one-year follow-up examination. The null hypothesis tested will be that there is no statistically significant difference in success rate between both materials in indirect pulp capping of permanent mature molars with deep carious lesions.
The aim of this 2-arm parallel trial was to evaluate enamel demineralization after an indirect bonding technique in comparison to a direct bonding technique group using the quantitative light-induced fluorescence method. Thirty-six patients who needed fixed orthodontic treatment were randomly separated into either the direct bonding group or the indirect bonding group. Eligibility criteria included moderate crowding in the maxillary and mandibular dental arch, good oral hygiene, absence of craniofacial anomalies, no previous orthodontic treatment and no deciduous, congenitally missing or extracted teeth. Randomization was made at the start of the study with a statistical analysis program (SAS Institute Inc., Cary, NC, USA.). For the patients in the indirect bonding group, bonding was performed with a flowable composite adhesive, while the patients in the direct bonding group received a bonding procedure with a conventional composite adhesive. Records were taken using quantitative light-induced fluorescence (QLF) with a Digital Biluminator (Inspektor Research Systems, Amsterdam, the Netherlands) in the pretreatment and posttreatment examination phases. The presence and extent of lesions on the buccal surfaces of all teeth, except the molar teeth, were assessed. The fluorescence loss, lesion area and percentage of fluorescence loss were determined using the system's software. The primary outcome of this study was evaluation of the effects of bonding techniques on white spot lesion formation by using the QLF method. Random sequence generation was performed with a computerized random 1:1 allocation using block sizes of 4. It was not possible for the clinicians and their interventions to be blocked. The patients and the specialists were blinded to the treatment groups when their treatment groups were aware.
Vital pulp therapy (VPT) is a general term for multiple procedures (indirect pulp cap, direct pulp cap and pulpotomy) all directed toward preserving pulp vitality and enable complete root development in immature teeth. The aim of this study is to evaluate the clinical, radiographic and histologic (if any teeth later are doomed for extraction for orthodontic or other reasons) success rate of VPT on treating cariously exposed permanent teeth with developmental defects of enamel. This will be a a prospective case series study including children between 6-16 years old having tooth with enamel hypomineralization defect with deep caries, restorable teeth , and no signs of infection. The teeth will be followed up both clinically and radiographically for 1 year after treatment. It is expected that the teeth will maintain vitality with resolution of symptoms (if present) and completion of root development in immature teeth after vital pulp therapy.
The aim of this study was to evaluate the survival of direct composite resin restorations in primary molars using different methods of isolation of the operative field: absolute isolation (local anesthesia, use of dental clamp and rubber dam) and relative isolation (cotton rollers and saliva ejector) by a randomized clinical trial. All composite restorations will be performed on children aged 4 to 10 years who present at least one dentin caries lesion or restoration needing replacement, without pulp involvement in a primary tooth. The treatments will be performed in the dental clinic of the University of São Paulo (FOUSP) by trained operators. The teeth will be randomized between the groups: Absolute Isolation (AI) and Relative Isolation (IR) and restored with composite resin (Scotchbond Universal Adhesive adhesive system and Filtek BulkFill composite resin - 3M ESPE) stratified by surface (single or multi surface). Restoration evaluation will be performed after 6, 12, 18, and 24 months by a blind, trained and calibrated examiner. As a primary outcome, the survival of the restorations will be evaluated. The secondary outcomes involve the procedure time (in minutes), professional and material cost (in Brazilian reais), as well as the cost-effectiveness of the restorations and the discomfort reported by the patient (measured using the Wong-Baker scale). The Kaplan-Meier survival analysis and log-rank test will be applied to the survival of the restoration. All variables will be modeled and compared with a Cox regression model of shared fragility. The discomfort reported by the patient will be analyzed by Ordinal Logistic Regression (α = 5%).
Objectives: Aim of the study The objective is to conduct an RCT to evaluate the effectiveness of miswak in comparison with standard caries preventive measures for the prevention of new carious lesions in high caries risk patients. -Research hypothesis (alternative hypothesis): This study will be designed to test the alternative hypothesis that using miswak in addition to standard preventive measures will show significant difference over using standard preventive measures alone in preventing incidence of new carious lesions in high caries risk patients.
Basic standard of care emphasis only tooth brushing and flossing without addressing individual pathological factors. For this reason, randomized controlled clinical trials on personalized caries management are needed to be able to compare the effectiveness of personalized caries management to basic standard of care. This is especially true in high caries risk populations and more so for young adults who stand to benefit the most from working towards a caries free adulthood.
Remineralization effect of CPP-ACP and Fluoride (MI varnish) versus Fluoride varnish on white spot lesions in maxillary primary incisors
This double-blind RCT aimed to evaluate the effect of sugar-free snacks on caries risk in 6-9 years-old schoolchildren. Considering a 20% difference among groups, the number of subjects needed per group was set in 87. Two-hundred-seventy-one children at risk for caries measured through Cariogram were selected and randomly assigned to three groups consuming twice a day snacks containing Stevia or Maltitol or sugar for 42 days. Parents filled out a standardized questionnaire regarding personal, medical and oral behavioural information. Bleeding on probing, plaque pH and cariogenic microflora were assessed at baseline (t0), after 21 (t1) and 42 days of snacks' use (t2) and 120 days after the end of use (t3). Cariogram was also repeated at t2.
The objective is to conduct an randomized controlled clinical trial to evaluate the effectiveness of grape seeds extract mouth wash in comparison with standard caries preventive measures for the prevention of new carious lesions in high caries risk patients. This study will be designed to test the alternative hypothesis that using grape seed extract mouth wash in addition to standard preventive measures will show significant difference over using standard preventive measures alone in preventing incidence of new carious lesions in high caries risk patients
Fluoride is very effective in preventing dental decay (cavities) when applied in the form of a varnish on tooth surfaces. The purpose of this study is to verify if fluoride-releasing primer (OpalSeal) offers more protection against early dental decay (cavity) compared to conventional primer (Transbond XT) during treatment with braces.
