This prospective clinical study aims to evaluate the diagnostic accuracy of intraoral scans (IOS) for the detection of dental plaque and caries. The diagnostic performance of IOS will be compared with current clinical reference standards. For plaque assessment, IOS-based evaluation will be compared with plaque detection using disclosing agents. For caries detection, IOS (including white-light imaging and caries detection features) will be compared with conventional visual inspection and bitewing radiography. Adult patients aged 18 to 70 years will be included.

Inclusion Criteria:

• Adults aged 18 to 70 years
• Not pregnant and not planning pregnant
• At least 20 teeth present
• Ability to provide informed consent

Exclusion Criteria:

• Conditions that prevent proper intraoral examination (e.g., severe gag reflex, limited mouth opening)
• patient unable to provide informed consent

Adult patients aged 18 to 70 years undergoing intraoral examination in a clinical setting, with at least 20 teeth, who are not pregnant and able to provide informed consent.
