“…A mixture of different fluorescent chromophores is present in human calculus, as has already been suggested [17,20]. Supragingival calculus may have porphyrin derivatives noticeable by the Soret bands at approximately 405 nm and by less intense Q bands at higher wavelengths [17,20,21].…”

Fluorescence results from a process that occurs under certain conditions in molecules known as fluorophores, fluorochromes or fluorescent dyes when they absorb light. The molecule is excited to a higher energy state and emits fluorescent light. The emission wavelength is always higher than the excitation wavelength. Optical diagnoses by fluorescence can be used in medicine and dentistry. It does not cause injury to tissues because it is a noninvasive method and can add benefits to clinical treatments. The aim of this case report was to apply an optical fluorescence system for wide-field image viewing and visual monitoring of the management of plaque and dental calculus before and after periodontal scaling to improve the diagnoses and follow-up of patients with periodontal disease. The results suggest that it is possible to observe, with a fluorescence system, residual plaque and calculus that were not easily seen by the naked eye during oral inspection. Thus, the optical technique can potentially improve periodontal screening efforts, especially in patients undergoing periodontal maintenance.

“…13 Results of one in vitro evaluation have been published; 13 however, the examination method used neither involved mounted teeth with replication of soft tissues nor there was a comparison with a conventional periodontal probe undertaken. 13 One small clinical study involving the examination of teeth from a total of eight patients has been undertaken; 14 however, this neither reported sensitivity or specificity values nor were data presented on the types of teeth examined and the extent of pocketing present at the time of the examination. A recent review of calculus detection methods 15 concluded that the utility of this spectro-optical approach had yet to be examined thoroughly.…”

Differential reflectometry versus tactile sense detection of subgingival calculus in dentistry

Abstract. Detecting dental calculus is clinically challenging in dentistry. This study used typodonts with extracted premolar and molar teeth and simulated gingival tissue to compare the performance of differential reflectometry and periodontal probing. A total of 30 extracted teeth were set in an anatomical configuration in stone to create three typodonts. Clear polyvinyl siloxane impression material was placed to replicate the periodontal soft tissues. Pocket depths ranged from 10 to 15 mm. The three models were placed in a phantom head, and an experienced dentist assessed the presence of subgingival calculus first using the DetecTar (differential reflectometry) and then a periodontal probe. Scores from these two different methods were compared to the gold standard (direct examination of the root surface using 20× magnification) to determine the accuracy and reproducibility. Differential reflectometry was more accurate than tactile assessment (79% versus 60%), and its reproducibility was also higher (Cohen kappa 0.54 versus 0.39). Both methods performed better on single rooted premolar teeth than on multirooted teeth. These laboratory results indicate that differential reflectometry allows more accurate and reproducible detection of subgingival calculus than conventional probing, and supports its use for supplementing traditional periodontal examination methods in dental practice.

Improved detection of subgingival calculus by laser fluorescence over differential reflectometry

Laser fluorescence (LF) and differential reflectometry (DR) are two new optical methods which have been used to help diagnose subgingival deposits of dental calculus. This study compared the performance of LF using the KEY3 laser system versus DR using the DetecTar system under controlled laboratory conditions designed to simulate clinical conditions as much as possible. A total of 30 extracted human posterior teeth were set in an anatomical configuration in stone typodonts with impression material replicating the periodontal soft tissues. LF was more accurate than DR (76.2% vs. 68.2%) and gave higher reproducibility (Bangdiwala's B statistic 0.71 vs. 0.54). The better performance of LF makes it the preferred option of the two methods for detection of subgingival dental calculus.

The effectiveness of a novel optical probe in subgingival calculus detection

Abstract: It was shown that the optical detection system identifies subgingival calculus with a high efficacy and therefore, may be a support for the operator to determine the endpoint of root surface instrumentation.
