Classification of carious lesions of teeth refers to the categorization of tooth decay based on various factors such as location, severity, and progression. This classification system helps dentists and dental professionals in diagnosing and treating dental caries effectively.

One commonly used classification system is the International Caries Detection and Assessment System (ICDAS), which provides a standardized approach to classify carious lesions. According to ICDAS, carious lesions are classified into six main categories:

  1. Sound tooth surface: This category represents a healthy tooth surface with no signs of caries or demineralization.

  2. Initial caries: This category includes non-cavitated lesions where the enamel surface shows signs of demineralization, such as white spots or discoloration. These lesions can be reversed with proper oral hygiene and remineralization techniques.

  3. Moderate caries: In this category, the carious lesion progresses beyond the enamel and reaches the dentin. The lesion may appear as a cavitated area with visible signs of decay, such as brown or black discoloration.

  4. Advanced caries: This category represents extensive decay that involves the dentin and may reach the pulp chamber. The lesion appears as a deep cavity with potential symptoms like tooth sensitivity, pain, or infection.

  5. Severe caries: This category indicates severe decay that has extensively damaged the tooth structure, including the pulp chamber. The tooth may exhibit symptoms like severe pain, abscess formation, or tooth loss.

  6. Arrested caries: This category refers to carious lesions that have stopped progressing due to remineralization or dental treatment. The lesion may appear as a dark, hard, or discolored area on the tooth surface.

Apart from the ICDAS classification, carious lesions can also be classified based on their location, such as occlusal caries (on the biting surface), proximal caries (between teeth), or root caries (on the root surface).

Understanding the classification of carious lesions is crucial for dentists to determine the appropriate treatment plan. Early detection and intervention of caries can help prevent further damage to the tooth structure and maintain optimal oral health. Regular dental check-ups and good oral hygiene practices are essential in preventing and managing carious lesions effectively.
