Filter by:The trial aimed to evaluate the sealant retention, patient's preference and chair time needed during pit and fissure sealant placement under two isolation techniques [Dryshield system (DS) and cotton roll isolation (CRI)] in a university setting.
comparing retention of CAD CAM metallic and Poly Ether Ether Ketone (PEEK) partial dentures in Kennedy class I casses
A randomized clinical trial is set out to compare the effectiveness of two types of fixed retainer (multistranded stainless steel and PEEK types) in maintaining the stability of lower anterior teeth with less failure rate.
To assess the effect of piezocision on post-orthodontic lower anterior teeth stability as compared to fiberotomy and conventional Hawley retainers.
The intervention program proof-of-concept was assessed as a single-arm, within-subjects clinical study with a target enrollment of 10 participants with possible or probable amnestic MCI. The protocol required participants to complete a pre-intervention assessment within two weeks of beginning the intervention, attend seven, one-hour intervention group sessions across six weeks, complete a post-assessment and interview in the final week of the intervention, and complete weekly surveys throughout the intervention.
Participants will be recruited for inclusion at a routine adjustment appointment prior to planned removal of the appliances. Following removal of the appliances, consenting participants will be randomly allocated to one of two groups by computer-generated random allocation. Allocation will be concealed from the treating clinician using of an opaque sealed envelope system. Standard stone model records will be available for all participants following removal of the appliances (T0). Participants in both groups will have follow-up scheduled for 3 (T1), 6 (T2) and 12 (T3) months following removal of the braces. All participants will be instructed to wear standard clear, plastic (Essix-type) retainers on a full-time basis for 6 months, followed by night-time wear for a further 6 months. A micro-electronic timer will be integrated within the upper Essix-type retainer. All participants will be given standard advice at each recall visit. Participants in the intervention group will receive tailored electronic reminders in the form of a mobile application. The frequency and content of the reminders will be informed by qualitative interviews involving participants from an allied trial, and from posts related to orthodontic retainers shared on social media. Instructions on the necessary duration of retention, maintenance of retainers, departmental details, allied to advice on appropriate management for appliance breakages, and delineation of the implication of suboptimal retainer wear will be included. Also, information related the debond visit and maintenance of optimal oral hygiene levels will be incorporated in the mobile application. Participants in the control group will not receive additional reminders. Treating clinicians will be kept blind to the study group. All patients failing an appointment will be sent another. Those wishing to withdraw from the trial may do so at any point without affecting continuing care with records taken at the point of withdrawal from the study with data analysis on an intention to treat basis. Thereafter, patient experiences with electronic reminders will be evaluated on a subset of participants using one-to-one interviews.
Conventional complete overdenture will be made to ectodermal dysplasia patients, a week after delivery and after 3 months Patient satisfaction, retention and periodontal condition will be assessed. the denture will be taken from the patient for 2 weeks.Acrylic telescopes will be replaced with soft liner and again Patient satisfaction, retention and periodontal condition will be assessed a week after delivery and 3 months later.
The purpose of this trial is to evaluate and compare stability after orthodontic treatment with an Essix retainer and a bonded cuspid-to-cuspid retainer (CTC), respectively in the mandibular arch and longitudinally follow these patients over time up to 5 years. The patients' perceptions of the two methods are also evaluated with questionnaires during the follow-up period. A further aim of this study is to analyze the relationship between diagnosis, treatment outcome, treatment time, age at start of treatment and stability with an Essix retainer in the maxilla. The null hypotheses are: - that there is no difference in retention capacity between Essix retainer and cuspid-to-cuspid retainer - that there is no difference in patients' perception between Essix retainer and cuspid-to-cuspid retainer - that there is no difference in retention capacity for Essix retainer in the maxilla concerning diagnosis before treatment, treatment outcomes, treatment time and age at start of treatment
Evaluation of the retention of upper removable partial denture constructed from two different flexible thermoplastic materials.(BRE-FLEX and PEEK).
It is a clinical trial which employs a split mouth design to assess the retention of a moisture tolerant resin based sealant and the ART(Atraumatic restorative treatment) sealants on a representative sample of 7- 12 year old school children of a district in Belgaum, Karnataka, India.
