Select the false principal for DMF score
1) Last permanent molars are included in scoring
2) Naturally exfoliated teeth should not be taken into consideration
3) Both A and B
4) Endodontically treated tooth should be considered

📝 Explanation:

DMF (Decayed, Missing, Filled) scores are used to measure past and present dental caries experience in permanent teeth. The principles for DMF scoring are:

All permanent teeth are included, which means last permanent molars are included in scoring .

Teeth lost due to reasons other than caries (e.g., trauma, naturally exfoliated primary teeth) are not counted as 'missing' .

An endodontically treated tooth is typically considered 'filled' because the treatment is a consequence of deep decay, so it should be included in the score . Therefore, the statement that they should be considered is a true principal, making it the false option among the choices provided (which asks for the false principal).
