This study compared patterns of oral care provided by predoctoral dental students for patients seeking treatment at the University of Washington (UW) with patterns reported for general dental offices by the Washington Dental Service (WDS). Dental care included about 5 million services provided to 880,317 patients by 2,803 WDS general dentists and about 45,600 dental services provided to 9,488 patients by 155 UW dental students during 1999. There was high fidelity between databases and randomly surveyed patient records for treatment provided in both UW (95 percent) and WDS (97 percent) populations. While patient age patterns were generally similar, UW students completed more procedures for young children and for adults older than seventy-four years but completed fewer procedures for age groups of from thirteen to eighteen and from forty-five to fifty-four than general dental offices. The relative mix of all services completed by UW and WDS providers was similar (ANOVA, P=0.82). Within categories of service, the percentage of total services completed by students compared to those submitted by community dentists to WDS was about the same for examinations, radiographs, fluoride and sealants, amalgams, composites, single crowns, and endodontics. The percentage of total procedures completed showed a greater emphasis by UW students on inlays/onlays, dentures, extractions, and periodontal maintenance, and lesser experience with implants, orthodontics, sedation, and emergency procedures than general dental offices. We conclude that the relative distribution of clinical services provided by UW dental students is comparable to those procedures reported to WDS by dental offices in the adjacent community.

Aim: This study aimed to evaluate and compare the results of combination therapy involving bone grafting and two different resorbable collagen membranes in 1-, 2- and 3-wall infrabony defects.
Methods: A total of 174 patients with infrabony defects (≥ 7 mm periodontal probing depth) were randomized to receive deproteinized bovine bone mineral (DBBM) with either a native porcine non-crosslinked collagen membrane (N-CM, control, n = 87) or a novel porcine crosslinked collagen membrane (C-CM, test, n = 87). Clinical parameters, including periodontal probing depth (PPD), clinical attachment level (CAL), and gingival recession (GR), were recorded at baseline, 12 weeks, and 24 weeks.

Background: A large number of older people depend on others for help with their daily personal care, including oral health care. Nursing home and elder-care staff often face challenges identifying older people, who are exposed to or at an increased risk of oral diseases. Thus, the aim of this study was to identify risk factors that non-dental care staff can use to identify older people at risk of oral diseases and poor oral hygiene.

Background: This study aims to compare design, phase transformation behavior, and torsional resistance of the ProGlider (PG) and ProTaper ultimate slider (PUS) and to compare the performance of two files in the glide-path preparation of a double-curved artificial canal.
Methods: Scanning electron microscopy, micro-computed tomography, and differential scanning calorimetry were used to characterize the samples. A torsional resistance test was performed to obtain ultimate strength and distortion angle.

Background: There is a paucity of data on oral health problems among the residents of Fanteakwa districts (South and North) in the Eastern region of Ghana. Therefore, this study assessed the prevalence and factors associated with self-reported oral health problems in the Fanteakwa districts of Ghana.
Methods: This community-based cross-sectional study targeted residents of the towns of the Fanteakwa districts, who have not had any dental care visit in the past six months preceding the study.

Karnofsky Performance Status (KPS) is a widely used scale to assess performance status. KPS ≥ 50% implies that patients can live at home. Therefore, maintaining KPS ≥ 50% is important to improve the quality of life of patients with glioblastoma, whose median survival is less than 2 years.
