Summary
The International Caries Detection and Assessment System (ICDAS) and fluorescence camera (FC) accurately detect enamel and dentin caries in primary teeth. Other methods like DIAGNOdent (LF, LFpen) also showed good performance for dentin lesions.
Area of Science:
- Pediatric Dentistry
- Dental Diagnostics
- Caries Research
Background:
- Accurate detection of occlusal caries in primary teeth is crucial for timely intervention.
- Various diagnostic methods exist, but their comparative performance in primary dentition requires further evaluation.
Purpose of the Study:
- To compare the diagnostic performance of the International Caries Detection and Assessment System (ICDAS), bitewing radiography (BW), and fluorescence-based methods (DIAGNOdent, LFpen, VistaProof fluorescence camera) for detecting occlusal caries in primary teeth.
Main Methods:
- Seventy-nine primary molars were assessed by two examiners using ICDAS, BW, LF, LFpen, and FC.
- Histological analysis served as the gold standard for caries extent.
- Optimal cutoff limits were determined for fluorescence-based methods.
Main Results:
- ICDAS and FC showed higher sensitivity for enamel and dentin lesions (D1).
- For dentin lesions (D3), LFpen and FC demonstrated the highest sensitivity (1.00 and 0.91), while FC, ICDAS, BW, and LF had high specificity.
- The area under the ROC curve (Az) ranged from 0.780 (BW) to 0.941 (LF), indicating good diagnostic accuracy for all tested methods.
Conclusions:
- ICDAS and FC are accurate for detecting enamel and dentin occlusal caries in primary teeth.
- ICDAS, LF, LFpen, and FC are suitable for detecting dentin lesions on primary teeth occlusal surfaces.
- All evaluated methods demonstrated good to excellent reproducibility.

01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
