Abstract
The caries prevalence detected through photographic assessments ranged from 30 percent to 39 percent in a sample of 138 children.
- Caries prevalence using photographic assessments was not significantly different from the 42 percent found in visual examinations.
- Sensitivity of the photographic method for caries detection was between 58-80 percent, while specificity ranged from 99.7-99.9 percent.
- Sensitivity was notably higher for primary teeth, ranging from 63-82 percent, and for children aged 7 and younger, between 67-78 percent.
- Inter-rater reliability for the photographic assessment showed substantial to almost perfect agreement, with Kappa values between 0.72 and 0.87.
