A laser fluorescence spectroscopy is convenient equipment of mutans streptococci detection

Abstract

We verified a laser fluorescence spectroscopy (DIAGNOdent) was an effective and simple equipment to measure mutans streptococci (MS). DIAGNOdent provides was developed by KaVo Dental and it was launched as a tactile detection device. Since the reflected light excited by the laser light is also generated from healthy tooth material and altered by certainty of postprandial brushing, this wavelength was considered to be a reaction related to MS in dental plaque and biofilm. In the patientʼs mouth irradiation of DIAGNOdent to all tooth surfaces to evaluate the reaction was measured using OralCare Dentocult^® SM. By measurement and examing the correlation between the DIAGNOdent measurement values and them, the possibility of using DIAGNOdent was examined. Results showed that 22 of 37 patientʼs with positive Dentocult^® SM values in plaque on teeth was positive DIAGNOdent values. Twenty-five out of 29 Dentocult^® SM negatives had DIAGNOdent values it was negatives. Plaque in In saliva 21out of 31 people who were positive the Dentocult^® values were positive the DIAGNOdent values. Seventeen out of 23 who were negative the Dentocult^® SM values had negative DIAGNOdent varues. DIAGNOdentʼs reaction and Dentocult^® SM values are significantly correlated. We found the DIAGNOdent was useful as an inspection device for convenient screening of MS in mouse. In daily clinical practice this device intends to facilitate the treatment of causal therapy.
