Active clinical trials for "Tooth Wear"

The study will examine the extent to which a group motivational intervention (ME) impacts retention, treatment compliance, and long-term outcomes in families with a history of, or high risk for, child maltreatment.

The study is designed as a pilot study. The primary objective of the current study is to collect data on the expression and progression of tooth structure loss in dental students under stressful conditions and different dietary habits using intraoral scanners (IOS). Stress levels will be evaluated using Percived Stress Scale (PSS-10). Eating habits will be queried using reflux and dietary questionnaires. The data obtained will later be used in the case-control design of a multicenter study on the same topic. Conducting the pilot study will allow for a critical evaluation of the study's design, participant retention rate, and recruitment process.

A randomized, controlled clinical trial is designed to analyze the wear of enamel by opposing polished monolithic zirconia crowns and by the polished veneer surfaces of metal-ceramic crowns. This single-blind pilot study will involve a total of 30 teeth that require full coverage crowns that oppose natural antagonist teeth. The objectives of this research are to test the following hypotheses: (1) differences between mean wear of antagonist enamel by polished monolithic zirconia crowns and by the polished veneer surface of metal-ceramic crowns are statistically significant; (2) differences between mean wear of antagonist enamel by opposing polished monolithic zirconia crowns and enamel by opposing enamel are statistically significant; and (3) differences between mean antagonist wear of enamel by opposing polished veneer surfaces of metal-ceramic crowns and enamel by opposing enamel are statistically significant.

To evaluate the change in patient Oral Health-related Quality of Life (OHRQoL) from wearing a cobalt chrome (CoCr) removable partial denture (RPD) to wearing the Solvay Dental 360TM polymer Removable Partial Denture (RPD) for 8 weeks.

Visit 1: Clinical examination and investigations will be carried out for the eligible patients including TMJ examination and intraoral examination for oral mucosa. Diagnostic charts will be prepared with full medical and dental history as well as radiographic records. Primary impression will be performed with irreversible hydro-colloid impression material (alginate), The impressions will be poured with type IV dental stone to obtain diagnostic casts, special tray will be constructed. Visit 2: Maxillary Face-bow will be recorded to mount the upper cast. The diagnostic casts will be mounted on semi adjustable articulator in centric occluding relation to evaluate the inter-arch distance. Visit 3: Secondary impression will be performed in special trays by elastomeric impression material. The impression will be poured into typeIV dental stone in order to obtain master cast. Visit 4: Trial denture base will be constructed and tried in patient's mouth for obtaining maxilla-mandibular relation using face bow record and centric relation record, then mounting of the casts on semi adjustable articulator will be done. The teeth will be set according to the randomization group. Visit 5: The denture bases will be tried in with acrylic teeth in patient's mouth. Visit 6: The denture will be delivered to the patient and occlusal adjustments will be done. Visit 7: Recall visit after one week, further adjustments will be done. The denture will be sent to the scanning center and given to the patient again. Visit 8: At 3 months follow up, the denture will be inspected for calculus and will be immersed in ultrasonic cleaner for 15 seconds to remove calculus and then scanned. Visit 9: At 6 months follow up, the denture will be inspected for calculus and will be immersed in ultrasonic cleaner for 15 seconds to remove calculus and then scanned. Visit 10: At 9 months follow up, the denture will be inspected for calculus and will be immersed in ultrasonic cleaner for 15 seconds to remove calculus and then scanned. The optical methods tend to fulfill the need for quantitative characterization of surface topography. Specimens will be photographed using USB Digital microscope with a built-in camera (Scope Capture Digital Microscope, Guangdong, China) connected with an IBM compatible personal computer using a fixed magnification of 120X.The images will be recorded with a resolution of 1280 × 1024 pixels per image. Digital microscope images will be cropped using Microsoft office picture manager to specify/standardize area of roughness measurement. The cropped images will be analyzed using WSxM software.

The cropped images will be analyzed using WSxM software.

This study compares the survival rates of both direct and indirect resin-based composite restorations in the treatment of severe tooth wear.

The aim of this randomized, controlled, prospective clinical trial is to evaluate the performances of two different universal adhesives and an etch&rinse adhesive in restoration of non-caries cervical lesions. Twenty patients will receive restorations. Lesions will be divided into 7 groups according to adhesive systems and application modes: GSE: Gluma Universal- self etch, GSL: Gluma Universal-selective etching, GER: Gluma Universal-etch&rinse, ASE: All Bond Universal- self etch, ASL: All Bond Universal- selective etching, AER: All Bond Universal- etch&rinse, SB (Control): Single Bond2+etch&rinse. Restorations (nano-hybrid composite) will be scored with regard to retention, marginal discoloration, marginal adaptation, recurrent caries and post operative sensitivity using modified USPHS criteria after 48 months. Two examiners who is not involved in the placement of restorations will conduct the evaluations. Descriptive statistics will be performed using Chi-square tests.

The purpose of this study is to examine the efficacy of techniques to enhance participation in parenting programs.

This study compares the associated risk factors between adults with tooth wear and age- and sex-matched controls without tooth wear.

The NHS is experiencing a significant workforce crisis across the service; with currently >130, 000 vacancies, therefore, national efforts to improve recruitment and retention are a priority. In maternity services, there are currently 2,500 WTE midwife vacancies and over three-quarters of Heads of Midwifery cite it is 'increasingly difficult' to fill these vacancies (RCM, 2022a; RCM, 2022b). A vital component of a sustainable workforce and safe maternity care is retaining newly qualified midwives (where attrition is currently high) and experienced midwives already working within the service. However, data repeatedly demonstrate dissatisfaction and intentions to leave the midwifery profession (RCM, 2022; RCM, 2022). Recognising the importance of retention, NSHEI allocated a one-off lump sum of £50,000 to each hospital Trust to specifically employ midwives to support retention efforts (NHSEI, 2022). However, to date, research has not captured contemporary midwifery attrition and retention insights with this role in place. Therefore, the purpose of this study is to capture, analyse and disseminate localised data from one NHS Trust to inform future local, regional and national retention projects. Specifically, this study aims to explore the views of midwives and student midwives at Torbay and South Devon NHS Foundation Trust regarding intentions to stay or leave either their current workplace and/or the profession. These subtle but salient differences are important as some may prefer to work elsewhere but remain in midwifery, conversely, others may be satisfied with their workplace but intend to leave the profession. We will also gather insights regarding the retention midwife role, their work to date and potential impact. We will gather the data via documentary review, a survey aimed at midwives and student midwives and 10-15 individual interviews. Using these insights, we will identify recommendations for the local, regional and national workstreams to inform future retention work.
