Abstract Objectives The aim of the present randomized, controlled clinical multicenter trial was to compare a polyethylenglycol (PEG) and a native collagen membrane (BG) for simultaneous guided bone regeneration (GBR) at bony dehiscence‐type defects around bone level titanium implants. Material and methods The study enrolled 117 patients requiring implant treatment in the posterior maxilla or mandible with expected buccal bony dehiscence‐type defects at the placed titanium implants. According...

Abstract Objectives The aim of the present prospective study was to assess the risk for disease recurrence following surgical therapy of peri‐implantitis. Material & Methods 73 patients (130 implants) treated surgically for peri‐implantitis were examined at 1 and 5 years after therapy. The primary outcome was recurrence/progression of disease defined as any of the following events: (i) bone loss >1.0 mm, (ii) surgical retreatment, (iii) implant removal/loss after year 1. Patient‐...

Abstract Objectives The aim of this study was to examine the microbial composition of early (after 3 days, D3) and mature biofilms (after 31 days, D31) on materials typically used in implant‐abutment build‐ups. Implant/abutment materials with different surface roughness values (Ra) were compared to detect differences in the quantity and quality of bacterial composition. Material and Methods Four different materials were investigated: rough implant surface (sand‐blasted acid‐etched titanium;...

Abstract Objectives To evaluate implant survival rate, any complications, and changes of residual alveolar bone height (RABH) using saline or platelet‐rich fibrin (PRF) filling after hydraulic transcrestal sinus lifting. Methods Dental implants were placed after hydraulic transcrestal sinus lifting and the filling of saline (20 patients) or PRF (20 patients). Outcome measurements were implant survival, any complications, and RABH changes. Cone‐beam computed tomography (CBCT) scans were...

Abstract Objectives This study investigated biofilm formation on discs of metal alloys, zirconia, and polyetherketoneketone in vivo. Material and Methods Sixteen healthy volunteers conducted two runs of 24 hours each wearing an intraoral splint with 15 discs representing five different materials (gold‐based [EL] and silver‐based [PA] noble metal alloys; zirconia [ZR]; polyetherketoneketone [PEKK]; titanium zirconium alloy [TiZr]). Safranin staining assays and colony forming unit (CFU) counts...

Abstract Objective To study the influence of peritoneal dialysis (PD) on the salivary metabolite profile of children and adolescents with renal failure. Materials and methods Healthy children/adolescents (n = 31; mean age: 12.18 ± 3.76) and children/adolescents subjected to PD (n = 12; mean age: 10.10 ± 4.25) were recruited. Oral health status assessed by...

Abstract Objectives SARS-CoV-2 is mainly transmitted by inhalation of droplets and aerosols. This puts healthcare professionals from specialties with close patient contact at high risk of nosocomial infections with SARS-CoV-2. In this context, preprocedural mouthrinses with hydrogen peroxide have been recommended before conducting intraoral procedures. Therefore, the aim of this study was to investigate the effects of a 1% hydrogen peroxide...

Abstract Objectives To investigate the prevalence of molar-incisor hypomineralization (MIH) in children aged 12 to 15 years in Beijing, China. Materials and methods A cross-sectional study was performed to recruit children aged 12 to 15 years old based on the method of multi-stage cluster random sampling during the Fourth National Oral Health Survey in Beijing,...

This study aimed to: (i) evaluate short‐term changes in dental fear during a 9‐month period among women and men, and (ii) evaluate whether the course and magnitude of changes in dental fear were associated with changes in depression and anxiety. The longitudinal data of the FinnBrain Birth Cohort Study were used. Out of 3808 women and 2623 men, 1984 women and 1082 men filled in the Modified Dental Anxiety Scale (MDAS) at gestational weeks 14 and 34, and 3 months after childbirth. Other questionnaires...

Abstract Purpose During orthodontic treatment with fixed appliances, demineralization around brackets often occurs. The aim of this in vitro study was to investigate the effect of the caries-protective self-assembling peptide P11‑4 (SAP P11-4) on the shear bond strength of metal brackets. Methods In all, 45 extracted human wisdom teeth were available...

Measuring quality of life (QOL) after head and neck cancer (HNC), is rapidly becoming the standard of care. The Head and Neck Database Listing Evidence on QOL (Handle-On-QOL) is a dedicated QOL resource that includes articles published from 1982 onwards. The aim of this study was to assess the completeness of Handle-On-QOL, when compared with other non-specific search engines. Six years were selected at random; 1982, 1990, 1998, 2003, 2006, 2016. Four search engines were used (Medline, EMBASE, CINAHL,...

Abstract Objective This study aimed to determine the expression of distinct matrix metalloproteinases, cytokines, and bone‐resorptive factors in temporomandibular joint osteoarthritis (TMJ‐OA) patients and their association with joint pain, mouth opening, and subchondral bone degeneration. Materials and methods Twelve patients affected with TMJ‐OA (n=5), disk displacement without reduction (DDWoR) (n=3), or disk displacement with reduction (DDWR) (n=4) were selected. Joint pain was quantified...
