Clinical subgingival calculus detection with a smart ultrasonic device: a pilot study.
(2,10,12,14) The need for absolute subgingival calculus removal came into question with reports of improved periodontal tissues in spite of remaining deposit.
Baseline data was then collected, which included gingival indices, full mouth periodontal probing, clinical attachment levels, bleeding upon probing, tactile detection of subgingival calculus with an 11/12 explorer and visual detection of subgingival calculus using the periodontal endoscope in the randomly assigned endoscope quadrant.
The results of this exam showed generalized inflammation, supra- and subgingival calculus, recession of 1 mm to 2 mm on #6 and #11 due to occlusal trauma, and horizontal bone loss in the molar and premolar areas of 2 mm to 5 mm (figures 1 and 2).
(11,12) Subgingival calculus is a frequent finding in patients with chronic periodontitis and it has been demonstrated that in the presence of poor oral hygiene, teeth with calculus demonstrate a higher rate of tissue attachment loss than teeth without calculus.
(5,33-36) When compared to the magnetostrictive unit, the piezoelectric was found to be more efficient in subgingival calculus removal and provided a smoother root surface.
In spite of the fact that calculus can serve as a reservoir for pathogenic microbes, the role of subgingival calculus, as an etiologic agent in chronic periodontitis, was relegated to secondary status once microbial biofilm was declared the primary, extrinsic etiologic factor.
* A clinical condition of either Case Type II Early Periodontitis, according to the American Dental Association (ADA) classification system, (24) and supragingival calculus covering the lingual surfaces of the mandibular anterior teeth and the buccal surfaces of the maxillary first molars with subgingival calculus ledges or rings
The new perio probe, available for both the DIAGNOdent Classic and pen versions, uses laser fluorescence of subgingival calculus to determine quantification of calculus left behind by standard root planing and scaling.
Results from multiple linear regression showed BOP and subgingival calculus are significant predictors of total treatment (p<05, R2 = .28).
Over half of the patients 16-years-old and younger in my chair had black subgingival calculus, heavy biofilm accumulation and moderate-to-severe inflammation.
Much of the clinical curriculum includes process and product evaluations that monitor and assess dental hygiene students' clinical abilities, especially related to the detection and removal of subgingival calculus. The purpose of this study was to determine if dental hygiene faculty were consistent in detecting "clickable" subgingival calculus that remained after the administration of a mock clinical board (MCB).
