Final answer:
The PTCE requires candidates to select a full quadrant plus two additional teeth with specific types of calculus on a required number of surfaces and demonstrate sufficient clinical attachment loss. Contact points between teeth are also assessed to evaluate the management of interproximal spaces.
Step-by-step explanation:
The requirements for case selection for the Practical Test of Clinical Excellence (PTCE) for teeth selection are specific and need to be carefully followed. Candidates are typically required to select one full quadrant of teeth within the oral cavity plus two additional individual teeth that demonstrate various aspects of periodontal conditions for examination and treatment. The teeth selected must exhibit specific types of calculus, both supra- and sub-gingival, with the requirement that the calculus covers a minimum number of tooth surfaces, which can vary depending on the examination's criteria.
Teeth eligibility is critical; they must have sufficient clinical attachment loss and periodontal pocket depths that allow for the demonstration of the candidate's skill in scaling and root planing. Additionally, the case selected should demonstrate contact points between the teeth to assess the student's ability to manage interproximal spaces as part of the comprehensive periodontal care.
