“…On the other hand, the use of a sharp probe along with the visual method does not appear to improve the diagnostic accuracy 16,21 . It may contaminate other sound sites 14 , damage the fissure 3 as well as facilitate the lesion's progression 29 . The main drawbacks of the conventional methods are that they still rely on the dentist's subjective interpretation, that it is difficult to evaluate a lesion's progression and that some clinicians decide on an unwarranted invasive intervention.…”

ABSTRACT:The reduction in caries prevalence has not occurred uniformly for all dental surfaces. As the occlusal surfaces are still the most likely sites for the development of lesions, new methods of diagnosis are still being evaluated. This study compared a laser fluorescence (LF) system (DIAGNOdent) with the Ekstrand's visual system for in vitro detection of occlusal caries. A total of 57 extracted molars with macroscopically intact occlusal surfaces were selected. Two-examiners assessed 110 sites by visual inspection (VI) and LF. After ten days from the first measurement, all teeth were re-evaluated through the same methods by each examiner. Caries extension was histologically assessed (X 40). The methods were compared by means of sensitivity, specificity, intra-and inter-examiner reproducibility and area under the ROC curve. The kappa's test showed good intra-and inter-examiner reproducibility for both methods. VI and LF showed similar sensitivities for both examiners, however, VI showed higher specificities than LF. The overall analysis, as demonstrated by the area under the ROC curve, showed that VI had a better performance than the LF device. It was concluded that the Ekstrand's visual system is more reliable than the LF device. LF should be considered only as an adjuvant for occlusal caries diagnosis.

Como as superfícies oclusais ainda são as mais susceptíveis ao desenvolvimento de lesões, novos métodos de diagnóstico ainda estão sendo avaliados. Este estudo comparou um sistema de fluorescência a laser (DIAGNOdent -DD) com o método visual de Ekstrand na detecção de cárie oclusal. Um total de 57 terceiros molares com superfícies oclusais macroscopicamente intactas foram selecionados. Dois examinadores examinaram 110 sítios por inspecção visual (IV) e DD. Após dez dias da primeira mensuração, todos os dentes foram novamente avaliados pelos mesmos métodos. A extensão de cárie foi validada por exame histológico (40 X). Os dados foram analisados quanto a sensibilidade, especificidade, reprodutibilidade intra e interexaminador e área sob a curva ROC. O teste kappa demonstrou boa reprodutibilidade intra e interexaminadores para ambos os métodos. A IV e o DD apresentaram sensibilidade semelhante para ambos os examinadores, entretanto, a IV apresentou maior especificidade que o DD. A análise geral, através da área sob a curva ROC, mostrou que a IV teve um melhor desempenho que o DD. Concluiu-se que o critério visual proposto por Ekstrand é mais confiável para o diagnóstico de cáries oclusais. O DD deve ser considerado apenas como um coadjuvante no exame de cárie em superfícies oclusais.

Purpose: Full-mouth disinfection enables to reduce the probability of cross contamination from untreated pockets to treated ones, for completing the entire SRP under local anesthesia with chlorhexidine as a mouth wash in two visits within 24 hours. This study aimed to compare the clinical effects of modified full-mouth disinfection (Fdis) after 6 months with those of conventional SRP (cSRP). Methods: Thirty non-smoking chronic periodontitis subjects were randomly allocated two groups. The Fdis group underwent the entire SRP under local anesthesia in two visits within 24 hours, a week after receiving supragingival scaling. A chlorhexidine (0.1%) solution was used for rinsing and subgingival irrigation for Fdis. The cSRP group received SRP per quadrant under local anesthesia at one-week intervals, one week after they had received scaling. Clinical parameters were recorded at baseline, after 1, 3 and 6 months. Results: There are significant (P < 0.05) decreases in the sulcus bleeding index, and plaque index, and the increases in gingival recession were significantly smaller with Fdis after six months compared with cSRP. There was significant improvement in the probing depth and clinical attachment level for initially medium-deep pockets (4-6mm) after Fdis compared with cSRP. Multi-rooted teeth showed significantly larger attachment gain up to six months after Fdis. Single-rooted teeth showed significantly more attachment gain, 1 and 6 months after Fdis.

“…As a result, the use of such instruments has been the subject of debate for years. Likewise, CP can transmit Streptococcus mutans from a contaminated fissure to a healthy fissure (Loesche et al, 1979). On the other hand, CP in combination with visual inspection (VI) does not improve the overall diagnostic performance of the exploration in application to caries of pits and fissures (Lussi, 1991;Lussi, 1993;McComb & Tam, 2001).…”

“…Enamel is a poor electrical conductor though caried enamel shows increased conductance versus intact enamel (Loesche et al, 1979). Demineralized enamel becomes more porous, fills with ion-containing fluid and minerals from saliva, and therefore exhibits increased electrical conductance (McComb & Tam, 2001).…”
