Asymptomatic chronic rhinosinusitis and osteitis in patients treated with multiple zygomatic implants: a long-term radiographic follow-up.

Purpose: The aim of this study was to investigate implant survival and the reactions of the bone and mucosa of the maxillary sinuses in patients treated with fixed dental prostheses supported by multiple zygomatic implants.

Materials And Methods: Between 2001 and 2007, patients with extensive resorption of the basal bone of the maxilla received multiple zygomatic implants without grafts. In 2012, the maxillary sinuses were examined with cone beam computed tomography.

Comparison of standard and task-specific enhancement of Digora storage phosphor images for approximal caries diagnosis.

Objectives: To compare approximal caries detection on Digora storage phosphor images pre-enhanced with the automatic "caries-specific Oslo enhancement procedure" ("Oslo-enhanced" method) and storage phosphor images individually enhanced by observers particularly experienced in digital imaging using standard brightness and contrast functions of the Digora system ("Digora-enhanced" method).

Methods: Seven staff members from four oral radiology departments rated 240 approximal surfaces for caries with regard to lesion depth in the inner and outer half of the enamel and dentine, using a 5-point confidence scale. The observations were validated histologically.

Comparison of ready-to-use EMDOGAIN-gel and EMDOGAIN in patients with chronic adult periodontitis.

Objectives: The aim of this multicenter trial was to compare the clinical and radiographical outcome of a ready-to-use Emdogain-gel (test) with the marketed Emdogain (control).

Methods: Subjects with bilateral infrabony defects > or =4 mm deep and > or =2 mm wide according to radiographs were selected. 88 subjects with probing pocket depth (PPD) > or =6 mm > or =1 month after supervised oral hygiene and scaling participated.

Guided tissue regeneration in the treatment of human infrabony defects. Clinical, radiographical and microbiological results: a pilot study.

The aim of the study was to evaluate the clinical, radiographical and microbiological outcome after using guided tissue regeneration (GTR) with a bioabsorbable membrane, Resolut. Subjects with bilateral infrabony defects at single rooted teeth were selected. A total of 22 teeth, 2 in each 1 of 7 patients and 4 in 2 patients, with probing pocket depth > or =5 mm, 3 months after scaling, participated.

Guided tissue regeneration for the treatment of intraosseous defects using a biabsorbable membrane. A controlled clinical study.

The aim of this controlled, clinical study was to evaluate guided tissue regeneration using a bioabsorbable membrane in periodontal intraosseous defects. Forty patients, each contributing one defect > or =4 mm in depth participated. The control group (18 individuals) received conventional flap therapy, while the test group (22 individuals) was treated using the bioabsorbable membrane, Guidor.
