Filter by:Objectives: To evaluate the 36-month clinical performance of Single Bond Universal Adhesive (SBU; 3M ESPE, Germany) in non-carious cervical lesions (NCCLs) using different modes adhesion approaches according to the FDI criteria. Material and methods: SBU Adhesive was applied in 252 NCCLs of 25 patients using different modes adhesion approaches: Self-etch (SE), selective-enamel-etching (SLE), total-etch (TE). All lesions were restored with nanohybrid resin composite. Restorations were evaluated at baseline, 6th, 12th, 18th, and 36th month using the FDI criteria. IBM SPSS Statistics for Windows, Version 24.0. program was used in the analysis. Differences between SE, SLE and TE groups were tested using Kruskal Wallis test. A value of p<0.05 was accepted as a criterion for statistical significance.
The overall objective was to evaluate the monitoring of tooth wear using the intraoral scanner. Forty-six participants were selected according to the established inclusion and exclusion criteria. Monitoring of tooth wear, evaluation of possible aetiological factors, as well as patient satisfaction with the use of the intraoral scanner were carried out.
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 . 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. 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. 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.
Objectives To compare oral health (dental caries, periodontal status, and erosive tooth wear (ETW)), diet and oral hygiene habits between obese and normal weight adolescents, and to explore possible risk associations. Materials and Methods In this case-control study, a convenient sample of 81 obese adolescents (age range 11-18) from a rehabilitation centre, and 81 age-sex-matched normal weight adolescents were selected. Groups were defined using the Body Mass Index and growth curves for Flemish. Oral health was measured using DMFT, gingival, plaque and BEWE index. A validated questionnaire was utilized to assess diet and oral hygiene habits.
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.

This study is a Randomized Controlled Trial (RCT). The aim of the study is to evaluate the necessity to test the desired increased Vertical Dimension of Occlusion (VDO) prior to restorative treatment of generalized tooth wear. Tooth wear is a physiological phenomenon, that when becoming pathological, can result in functional problems such as pain, reduced quality of life and esthetic impairment. Restorative treatment should be discussed with patients with severe or pathological tooth wear. The restorative treatment of generalized tooth wear includes restoration of teeth, separately, in increased VDO. The increment of VDO is based upon clinical parameters such as the amount of natural tooth tissue, the possibility to lengthen the anterior teeth in regard to an acceptable esthetics outcome, and the Free Way Space (FWS). The FWS is the intermaxillary space when the masticatory-muscles-complex is relaxed. Traditionally, it is believed that adapting to a new VDO results in clinical difficulties such as different speech, pain of the Temporo Mandibular Joint (TMJ), masticatory muscle pain, and increased masticatory muscles activity. The latter could result in an increased bite force and (possibly) an increased failure rate of restorations. Some operators, then, prefer to test the increment of VDO prior to restorative treatment to check if patients can adjust to the new VDO. This raises the question if the needed increment of VDO to restore worn dentitions should be checked prior to restorative treatment. The hypothesis in this study is that testing the needed increment of VDO prior to restorative treatment does not improve the restorative treatment. Patients with generalized severe tooth wear were included and restoratively treated with composite restorations. Prior to restorative treatment, patients were randomized to either receiving an acrylic Removable Appliance (RA) or no RA. The RA was worn for 3 weeks prior to restorative treatment and included the intended increment of VDO. These patients were asked to wear the RA during the whole day, except when eating. After restorative treatment, patients revisited our dental clinic after 1 month and after 1 year. Quality of life was assessed with questionnaires. FWS was assessed clinically. Restorations were checked for clinical acceptability, including small materials fractures.
Prospective observational study with 7-year follow up. 55 patients are included with moderate to severe tooth wear, whereby through informed consent the decision was taking to monitor the patients. At the baseline and 1, 3 5, and the 7-year recall digital 3D scans will be made, which will be compared and subtracted.
This study aimed to investigate the relationship between gastroesophageal reflux disease (GERD) and dental erosion and the alterations in oral tissues. This was a case-control study. The GERD group consisted of 50 individuals with endoscopic esophagitis who had gastroesophageal reflux symptoms, and the control group consisted of 50 healthy individuals. The prevalence of teeth wear and caries was evaluated using the Smith and Knight tooth wear index (TWI) and the decayed, missing, and filled teeth index (DMFT), respectively. Inflammatory mouth sensitivity, tongue sensitivity, nonspecific itching and burning, halitosis, dry mouth, teeth sensitivity, and the erythema of the soft and hard palatal mucosa and uvula were also evaluated. Stimulated saliva samples were collected, and the salivary flow rate, pH, and buffering capacity values were measured.
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.
This study compares the survival rates of both direct and indirect resin-based composite restorations in the treatment of severe tooth wear.
