Summary The purpose of this study was to evaluate enamel wear caused by monolithic zirconia crowns and compare with contralateral natural antagonists. Twenty were placed in 20 patients requiring full molar crowns. For measurement wear, impressions both jaws made at baseline after crown cementation 6‐month follow‐up. Mean maximum the occlusal contact areas crowns, their antagonists two measured use plaster replicas 3 D laser scanning methods. Wear differences investigated two‐sided paired...

The purpose of this study was to prospectively evaluate the short-term clinical performance and esthetics monolithic partially (i.e., facially) veneered zirconia single crowns (MZC PZC, respectively).Between September 2011 June 2013, 68 participants received 90 MZCs 72 PZCs. Clinical documentation performed at crown cementation (baseline), 6-month follow-up, then yearly thereafter using standardized report forms. Eight with 14 (eight six PZCs) dropped out during follow-up. Thus, 60 (28 male,...

Previous studies on the prevalence of signs temporomandibular disorders (TMD) in elderly people have used non-standardized and invalidated examination protocols. The different TMD this group is therefore still unclear. aim study was to evaluate subjects advanced aged, using a standardized validated protocol. Additionally, young were examined as control group. Fifty-eight old peoples' home inhabitants 44 Differences between groups assessed Mann-Whitney U-test or t-test. Geriatric more often...

The purpose of this prospective cohort study was to assess the performance tooth-supported, extended zirconia, fixed dental prostheses (FDPs). Thirty FDPs with span-lengths between 36 and 46 mm (mean: 40.33 mm), four seven units connector dimensions approximately 9 mm(2) were inserted (19 in posterior region, 11 including anterior teeth) using glass-ionomer cement assessed (aesthetic evaluation, failures, hypersensitivity/tooth vitality, secondary caries, pocket depth, decementation...

Summary The purpose of this prospective cohort study was to assess the performance tooth‐supported, long‐span, zirconia fixed dental prostheses (FDPs). Thirty FDPs with span lengths from 36 46 mm (mean 40·33 mm), 4–7 units and connector dimensions ∼9 2 were inserted (19 in posterior region, 11 including anterior teeth) using glass–ionomer cement. assessed (aesthetic evaluation, failures, hypersensitivity/tooth vitality, secondary caries, pocket depth, decementation, chipping) at baseline...

The objective of this cross-sectional study was to evaluate the effect prosthetic status on oral health-related quality life (OHRQoL) nursing home residents with or without dementia.The performed in 14 homes across federal state Baden-Württemberg, Germany. All eligible participants were included, and general medical information about their dental statuses collected. Geriatric Oral Health Assessment Index (GOHAI) administered OHRQoL. Mini-Mental State Examination (MMSE) served classify into...

To investigate the color stability of hybrid ceramics and to compare it composite lithium disilicate ceramics.One hundred eighty samples were fabricated processed with a semiautomatic grinding polishing device (final step: 1200 grit). After thermocycling, immersed in staining solution (five subgroups: water, red wine, curry, black tea, cola) for 4 weeks. A spectroradiometer was used determine CIE L*a*b*. Color measurements performed before (baseline, initial color), after 2 week storage each...

The aim of this study was to identify correlations between sleep bruxism (SB) and temporomandibular disorders (TMD) as diagnosed by means the research diagnostic criteria for (RDC/TMD). Sleep on basis I) validated questionnaires, II) clinical symptoms, III) electromyographic/electrocardiographic data. A total 110 subjects were included in study. Fifty-eight patients identified bruxers 52 nonbruxers. psychosocial assessment also performed. An RDC/TMD group-I diagnosis (myofascial pain) made...

Abstract Objectives To compare the strength and reliability of 3D-printed 3Y-TZP zirconia manufactured with various printing orientations staining. Materials methods A total one-hundred cylindrical specimens were designed fabricated using 3D processed according to ISO 6872 standards. Of these specimens, 80 printed new ZIPRO-D (ZD) ceramic printer. In this ZD group, 60 in a vertical orientation either stained after debinding (ZD1, x-orientation, n = 20) or not (ZD2, 20; ZD3, y-orientation,...

Objective: The purpose of this study was to identify which categories chronic stress increase during medical and dental education.Methods: 96 140 students were included. Chronic assessed before the beginning an undergraduate course after end same course. Wilcoxon signed-rank test for matched pairs used find differences between pre-course post-course situation. Differences using non-parametric tests.Results: For both value variables 'work overload' 'overextended at work' increased...

Abstract – Objectives: Translation, reliability analysis and validation of a German version the Geriatric/General Oral Health Assessment Index (GOHAI) was aim this study. Methods: Translation performed by forward–backward process. Validity assessed as convergent validity in comparison with another self‐perceived assessment oral health (OHIP‐14) group ( n = 218; mean age 73 years). Reliability proved terms internal consistency, inter‐item item‐scale correlations, stability (test–retest...

Objectives: The aim was to assess the prevalence of osteoarthrosis (OA) in temporomandibular joint (TMJ) a sample older people by use contrast agent-enhanced MRI. Methods: 30 patients (73–75 years old) were drawn from representative and examined clinically. shape condyle assessed using gadolinium-enhanced MR images, which evaluated two independent raters. Statistical assessment performed descriptive statistics, χ2 test kappa statistics. Results: Agreement between raters excellent with...

ABSTRACT Purpose: The objective of this retrospective study was to compare the incidence chipping implant‐supported, all‐ceramic, and metal–ceramic single crowns. Material Methods: One hundred fifty‐three patients (51.7% male, mean age 55.0 years) received 232 cemented implant‐supported seventy‐nine crowns had a metal framework (gold alloy) 53 were all‐ceramic (zirconia glass–ceramic veneer material). Age, gender, kind cementation, location restorations assessed as possible factors affecting...

Oral hygiene and health of the institutionalized elderly are frequently described as inadequate.This randomized single-blinded (outcome evaluation) study compared three types intervention for improving oral with a control. The purpose was to investigate whether there were any significant differences between control groups.One hundred six participants living in long-term care homes South-West Germany recruited randomly divided into four groups-three therapy groups one group. For all groups,...
