This study evaluated the ability of clinicians to detect residual calculus following subgingival scaling and root planing and compared the clinical detection to the microscopic presence and surface area occupied by calculus found on teeth extracted after instrumentation. Interexaminer and intraexaminer reproducibility in clinically detecting subgingival(More)
The healing response of non-molar sites, molar flat surface sites, and molar furcation sites was investigated in 19 adult periodontitis patients following a periodontal therapy of plaque control and root debridement. A total of 2472 sites were monitored by recordings of dental plaque, bleeding on probing, probing depth, and probing attachment levels every(More)
19 adult periodontitis patients were treated with plaque control and a single episode of root debridement. Results of this treatment were monitored in non-molar sites, molar flat surface sites, and molar furcation sites by probing attachment level measurements every 3rd month for 24 months. After 24 months, sites with probing attachment loss were identified(More)
1. Vital roots associated with periodontal osseous defects can be clinically submerged beneath a soft tissue flap. 2. Connective tissue fibers filled the submerged osseous defects and were oriented parallel to the root surfaces in the majority of cases. 3. New cementum lined the root surface at the base of two successfully submerged defects, but was not(More)
Clinical responses of facial grade II molar furcations to closed (C) versus open (O) debridement were evaluated. 25 teeth were treated at baseline (BL) with scaling/root planning (S/RP) and evaluated at 4 months. 12 of the teeth were then treated with open flap debridement and the remaining teeth were treated with further S/RP. Clinical parameters of(More)
Histatins, histidine-rich proteins found within parotid and submandibular secretions, are a novel class of endogenous peptides with antimicrobial properties. This masked, randomized, placebo-controlled preclinical investigation examined the effect of 3 topical histatins on the development of plaque and gingivitis in beagle dogs. 16, female, 1-year-old(More)
This study related 3-month clinical changes following scaling and root planning to the presence or absence of calculus on the root surfaces detected after extraction. Seven patients provided 646 sites evaluated for plaque, bleeding upon probing (BOP), probing pocket depth (PPD), and probing attachment level (PAL) at baseline and monthly following(More)
This study evaluated the diagnostic accuracy of periapical, tomographic, and cross-sectional occlusal radiographic techniques in the assessment of facial and lingual bone loss at implant obscured sites. An edentulous dry human mandible was prepared with implants in the incisor, premolar, and molar regions. Successive round bur sizes (No. 1 to 6) were used(More)
This study evaluated the use of tricalcium phosphate (TCP) ceramic implant material in periodontal osseous defects. Thirteen defects in two patients were treated with mucoperiosteal flaps and placement of TCP. The defects were evaluated clinically and radiographically utilizing standardized probe placement and radiographic technique. Clinically, there was a(More)
