Summary of Changes for the Class of 2026 CRDTS Dental Simulated Patient Examination outlines amendments across multiple exam parts. Part II updates Posterior Endodontics grading criteria, including integrity measures, pulp tissue debridement, and pulp horn removal, plus penalty-point triggers such as rubber dam remnants and pencil marks. Part III specifies Acadental Prime Layer bilayer teeth usage and reduces lingual wall height thresholds for anterior lithium disilicate crowns, with additional penalty areas. It further covers new periodontal measurement reporting and restorative criteria changes, including Class II prohibition of slot preparation, penalty points, and Class III gingival contact breaking rules. The document also details retake timing, scoring thresholds, attempt limits, fees guidance, and required forms, concluding with occlusal opening limiting rod insertion before procedure checks.

Summary of Changes Class of 2026 CRDTS Dental Simulated Patient Examination Part 1 DCTP – Time allotment 1 hour. Part II Endodontics: Three grading criteria in the Posterior Endodontics portion of the examination have been amended, as shown below: • Integrity of Oblique Ridge-Measure from the distal-oblique groove o SAT-Greater or equal to 3.0mm o ACC-Greater than 2.0mm but less than 3.0mm o SUB-Greater than 1.0mm but less than 2.0mm o DEF-Less than or equal to 1.00mm • Pulp Tissue Debridement o SAT-All Pulp Tissue is removed. o ACC-Pulp tissue remains but is not on the floor or covering the orifice of the canals. o SUB-Pulp tissue remains on the floor and covers 1 or more of the canal orifices. o DEF-All Pulp tissue remains. • Pulp Horn Removal o SAT-All Pulp Horns are removed through the access opening. o ACC-One or two of the pulp horns are not removed through the access opening. o SUB-All pulp horns have not been fully removed. • Penalty points will be assessed for: o Rubber Dam remnants o Pencil marks on teeth o Uncleanliness of models when turned in that would impede visual assessment of the procedure Part III Fixed Prosthodontics: CRDTS will be utilizing Acadental Prime Layer bilayer teeth, similar in enamel hardness to teeth \#3, 5 and 9, adjacent to the examination teeth for the fixed prosthodontic examination. Criteria of the Anterior Lithium Disilicate Ceramic Crown Preparation – Lingual Wall Height ranges have been reduced by 0.5 mm to accommodate for the OS3 M300 teeth, as follows: • Lingual Wall Height o SAT-The lingual wall height is optimally 1.0 mm or more. o ACC-The lingual wall height is 0.5-1.0mm. o SUB-The lingual wall height is less than .5mm. o DEF-There is no lingual wall. • Penalty points will be assessed for: o Marks on teeth o Uncleanliness of models when turned in that would impede visual assessment of the procedure Part IV Periodontal: Gingival recession measurements on the buccal and lingual of two teeth in the quadrant selected for periodontal treatment will be added to the periodontal progress sheet. Part V Restorative: CRDTS will be utilizing Acadental Prime Layer bilayer teeth, similar in enamel hardness to teeth \#3, 8 and 13, adjacent to the examination teeth for the Class II and Class III preparation procedures on the restorative examination. It continues to be emphasized that the Class II preparation CANNOT be a slot preparation. Criteria changes are noted in the restorative criteria shown below: • Outline Shape/Continuity/Extension o SAT-The outline form is smooth, rounded and flowing with no sharp curves or angles. o SUB-The outline form is inappropriately overextended so that it compromises the remaining marginal ridge/oblique ridge, and/or cusp(s) . The outline form is underextended and does not incorporate occlusal pits and grooves. o DEF-The outline form is inappropriately overextended so that it compromises, undermines and leaves unsupported the remaining marginal ridge/oblique ridge to the extent that thecavosurface margin is unsupported by dentin or the width of the marginal ridge/oblique ridge, is less than 1mm. • Penalty points will be assessed for: o Bonding agent o Rubber Dam remnants o Marks on teeth o Uncleanliness of models when turned in that would impede visual assessment of the procedure • Class III Prep: Gingival Contact Broken o SAT-The gingival contact must be broken, with gingival clearance up to 1mm. The incisal contact need not be broken, unless indicated by the location of the caries. If a lingual approach is initiated, facial contact may or may not be broken as long as the margin terminates in sound tooth structure. Fees: See website. Retakes: See CRDTS Retake Policy below If a candidate does not achieve a score at or above a 75% on a procedure, a 2nd Attempt retake option is available on-site after the dental examination has been completed at most examin

What scoring threshold triggers a retake option in this exam?

If a candidate does not achieve a score at or above 75% on a procedure, a 2nd Attempt retake option is available on-site after completion of the dental examination at most sites.

Which Part includes an important exception to which procedures must be retaken?

Part III (Prosthodontics) includes an exception: if the Bridge Factor has a sub-75% score, both posterior crown preparations on teeth #3 and #5 must be retaken.

What happens if a candidate has more than 5 hours of retake time available on-site?

They must finish remaining retake procedures at another date after exceeding the 5-hour on-site retake limit.
