8) Pilot research of this technology has indicated that clinicians could accurately detect subgingival calculus
and caries on 95% of all root surfaces.
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.
For calibration purposes, a convenience sample of 6 subjects with periodontitis and subgingival calculus
were recruited from the University of Minnesota School of Dentistry clinics.
Participants exhibited light to moderate amounts of non-tenacious subgingival calculus
on buccal, mesial, distal and lingual surfaces of selected test teeth and surfaces.
Case Type III Moderate Periodontitis or Case Type IV Advanced Periodontitis 24 and supragingival calculus on the line angles or covering some of the lingual surfaces of the mandibular anterior teeth and maxillary buccal surfaces of the fist molars with subgingival calculus
spicules or ledges
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 = .
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.
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).
This could allow for increased elimination of subgingival calculus
In pockets with subgingival calculus
, ultrasonic debridement may constitute the first approach to treatment, but because of difficulty in observing subgingival hard deposits and lack of tactile sensation when using ultrasonnic scalers, hand instruments are often used for final root preparation.
There was no evidence of subgingival calculus
or local irritants.
