Aim: To assess whether guided bone regeneration (GBR) treatment of peri-implantitis-related bony defects could improve healing compared to open flap debridement (OFD) at 36 months.
Materials And Methods: In a multi-centre, randomized clinical trial, 32 individuals received OFD (control group [CG]) and 34 GBR treatment (test group [TG]). Radiographic defect fill (RDF), probing pocket depth (PPD), bleeding on probing (BOP) suppuration (SUP), mucosal recession (MREC) and patient-reported outcomes (PROs) were evaluated at 36 months.
This case report describes the chairside fabrication of a monolithic posterior crown using a multilayer super-translucent zirconia material. According to the manufacturer's information, the newly introduced multilayer zirconia (4-YTZP) offers a unique combination of fracture strength (>850 MPa with speed-sintering) and improved optical properties, thus allowing a reduced minimum material thickness and optional temporary luting. By using up-to-date components of the CEREC system, including superfast dry-milling and a speed-sintering process, the fabrication of a monolithic zirconia crown is possible within an acceptable timeframe for the chairside workflow (60-75 min).

Radiographic defect fill (RDF), probing pocket depth (PPD), bleeding on probing (BOP), suppuration (SUP), recession (REC), cytokines (IL-1β, IL-1RA, IL-6, IL-8, IL-12, IP10, PDGF-BB, TNF-α, VEGF), and patient-reported outcomes (PROs) were evaluated at 3, 6, 9, and 12 months.
Background: The present cross-sectional study assessed oral health, nutritional condition, and oral health-related quality of life (OHRQoL) in older German people in need of care.
Methods: The participants were recruited from eight nursing homes (including three nursing homes with assisted living) and one mobile nursing service. Oral health, including dental status (decayed, missing and filled teeth (DMF-T), root caries), periodontal treatment needs, and prosthetic conditions, was recorded.
Purpose: A retrospective evaluation of extended anterior ceramic laminate veneers (EACVs) after a mean observational period of 10 years.
Methods: Thirty-one patients (20 females/11 males) underwent restoration with 101 adhesively luted, heat-pressed EACVs (maxilla, n = 65; mandible, n = 36).
Results: The 10 year survival rate was 91.
Objectives: Prospective practice-based clinical evaluation of chairside fabricated monolithic partial crowns composed of zirconia-containing lithium silicate (ZLS) ceramic material.
Materials And Methods: Between October 2013 and September 2014, 71 patients were restored with 92 partial crowns on vital or sufficiently endodontically treated teeth. The monolithic restorations were fabricated chairside (Cerec SW 4.
Aim of this cross-sectional study was to investigate the prevalence of selected potentially periodontal pathogenic bacteria in different sites of patients with tongue piercing (TP) in comparison to a control group (C). Fifty participants in each group were recruited. Samples from the biofilm originating from the piercing surface (TP group), periodontal pocket, tongue as well as cheek surface were examined regarding presence of 11 selected potentially periodontal pathogenic bacteria based on polymerase-chain reaction (PCR).

Furthermore, different piercing related factors and the presence of habits should be considered regarding their potential association to piercing-related complications.
Material And Methods: Participants with tongue piercing (n = 50) and a matched control (n = 50) were included.

Purpose: This dental practice-based pilot study aimed to investigate the efficacy of diabetes mellitus (DM) screening based on questionnaire replies.
Materials And Methods: 116 patients were screened in a private dental practice when visiting the dentist for a regular check-up. The Find-Risk (FR) questionnaire was used for diabetes screening.
Objective: Retrospective evaluation of the clinical performance of tooth-supported overdentures retained by resilient telescopic crowns with occlusal clearance fit (ODRTC) in severely reduced dentition (1-3 remaining teeth).
Materials And Methods: A total of 313 ODRTCs were inserted in an undergraduate prosthodontic program (University Medical Center, Goettingen, Germany) between 2000 und 2012. Data regarding 263 ODRTCs in 221 patients were reevaluated (observational period: 64.
Purpose: The aim of this retrospective cross-sectional study was to evaluate whether salivary findings of active matrix-metalloproteinase 8 (aMMP-8) chairside (point of care; POC) tests were associated with periodontal risk assessment parameters in patients receiving supportive periodontal therapy (SPT).
Methods: A total of 125 patients receiving regular SPT were included, and their records were examined. The following inclusion criteria were used: a diagnosis of chronic periodontitis, at least 1 non-surgical periodontal treatment (scaling and root planning) with following regular SPT (minimum once a year), at least 6 remaining teeth, and clinical and aMMP-8 findings that were obtained at the same appointment.
This in vitro study evaluated the effects of different abutment axial heights on the retentiveness of adhesively and self-adhesively luted zirconia copings. Ankylos implants were embedded in resin blocks. Two groups of titanium abutments ("long", height: 6.
