Filter by:In geriatric patients, will the clinical performance of nano hydroxyapatite reinforced glass ionomer be better than conventional glass ionomer cement in treatment of root caries lesions over one year follow up?
The purpose of this double-blind, randomized trial is to compare the clinical performance of a composite restorations in root surface carious lesions with or without resin modified glass ionomer lining.
This is a split-mouth, randomized clinical study that evaluating the 36-month performance of different restorative materials in the treatment of root caries lesions. A total of 110 restorations were randomly placed, half using resin composite (Spectrum TPH3) and the other half using the resin-modified glass ionomer cement (Riva Light Cure). Restorations were evaluated at the baseline, 6, 12, 18,24 and 36 months according to the USPHS criteria.
The main objective of this study is to compare the effectiveness and cost-effectiveness of 4-monthly application of 10% povidone iodine solution followed by 5% sodium fluoride varnish with those of annual application of 38% silver diammine fluoride solution on the prevention of new dental root caries in elders. A secondary objective is to compare the effectiveness of the two interventions mentioned above on arresting (halting the progression) active root surface caries in the elders, thus avoiding the need for placing dental restorations. This proposed study is a randomized double-blind controlled clinical trial with 24-month follow-up. A total of 353 elders aged 60 years or above living in residential homes or attending long-term care facilities in different districts in Hong Kong were recruited. Baseline clinical examination will be conducted by two calibrated examiners in the homes using an intra-oral LED light, dental mirrors and probes. Subjects were randomly allocated to one of the two study groups: 1) positive control - received annual application of 38% silver diammine fluoride solution; and 2) test - received application of 10% povidone iodine solution followed by application of 5% sodium fluoride varnish every 4 months. Follow-up examinations will be carried out after 12 and 24 months by the same blinded examiners to assess the clinical outcomes, i.e. whether new dental caries has developed and whether the active root surface caries lesions found at baseline have become arrested (hardened).
This study measures and compares the effect of silver diamine fluoride (SDF) on caries increment in removable partial denture wearers. Half of the participants will SDF and while the other half will receive placebo.
This study will involve filling teeth which have decay on their roots with three different filling materials. Patients will attend Cork University Dental School and hospital for a clinical examination and to complete a questionnaire describing how they feel about the comfort and appearance of their teeth. Patients will be asked to provide a sample of saliva by spitting into a tube. This saliva will be tested to see what levels of bacteria are present and how well their saliva neutralises acid in their diet. This is used to assess how high or low the patient's risk of dental decay is. They will also complete a questionnaire about the amount of sugar in their diet and how often they clean their teeth. If the exam shows that any teeth are so decayed that they cannot be filled, the patient will then be offered extraction of these teeth. All treatment will be discussed with the patient. Patients will be randomly assigned one of the three materials and this material will be used for their fillings. Patients will not know which of the three materials they received but all three materials are already in use in dentistry and all of the elements of each treatment plan are well recognised, routine dental procedures. After all the treatment has been completed, each patient will be shown how best to take care of their teeth and how to manage their sugar intake to reduce their risk of further decay. Patients will be given appointments to return for review at 6 months, 12 months, 18 months and 24 months after treatment. This will include a dental examination and dental impressions will be taken. These are used to measure how the restorative materials wear over time. Patients will also be asked to complete again the two questionnaires that they completed at their first visit to see if any of their answers have changed.
