Fluorescent Imaging System as a Monitoring Tool for Dental Fluorosis
Objectives: 1.To evaluate the use of fluorescent imaging for the quantification of dental fluorosis in an epidemiological survey and to determine the level of association using a standard clinical index.
2.To quantify the amount of effected areas of fluorosed tooth with respect to severity of fluorosis and fluoride level in water using QLF software.
Methods: Subjects who fulfilled the following inclusion criteria were included in the novel monitoring standardisation study.
School children of age 8 to 13 years with good general health.Subjects with both maxillary incisors fully erupted.
Subjects parents who will give consent to participate in the study and Subjects who were lifelong residents of their particular locality & used drinking water from one of three major sources identified from birth.
With complete records on of History of residence,School and Age ,Source of water use from birth to age three and Current water use for both cooking and drinking.
Drinking water samples fluoride concentration analysis was carried out with Specific Ion Electrode method OAKTON Fluoride Ion Selective Electrode Equipment, USA
Two Clinical examiners trained and calibrated for Dean’s Index 1942 ,Thylstrup and Fejerskov Index 1978 examined
Left maxillary central incisor.
QLF and White light polarized light images of teeth were captured with Florescent Camera using
Inspektor Research System bv, Amsterdam, Netherlands QLF-D Research SuiteTM -BiluminatorTM 2+B fluorescent camera system.and subjected to analysis using Its software.
Results:
The prevalence of 62 %to 78% dental fluorosis was observed in children between 8 to 13 years among those drinking water with fluoride levels between 0.001 to 2 ppm.Of which 39% of children had EOF at 0.7ppm which increased further to 58% at 1 ppm
Similarly, the QLF images showed a similar trend for . Group I 0.000-0.199, Group II 0.200-0.599,Group III 0.600-0.899,Group IV 0.900-1.599,Group V 1.600-1.999 with the Delta F values ranging from -9.26 to -19 ,99 fluorescence loss..
Conclusions: Based on ambient temperature and diet pattern 0.5-0.7ppm would be maximum permissible limit for drinking water fluoride instead of present BIS recommendation of 1ppm.
