Classify each tooth into a PDL group: Tooth 1 (HBSS,…
Dental trauma questions test protocol-level decisions — splint type, duration, follow-up timing — where one wrong detail means a wrong answer. This high-difficulty vignette tests your ability to work through clinical details and arrive at the correct management.
Three teeth arrive at the emergency clinic simultaneously from different patients: Tooth 1 was in HBSS (Save-a-Tooth kit) for 55 minutes after 3 minutes dry. Tooth 2 was in the patient's saliva (spit into cup) for 20 minutes after 25 minutes dry. Tooth 3 was wrapped in a wet paper towel for 65 minutes. All are closed apex. Classify each tooth into a PDL group: Tooth 1 (HBSS, 3min dry), Tooth 2 (saliva, 25min dry), Tooth 3 (wet towel, 65min).
- A. All three are Group 2 — any tooth stored in any medium with total time under 90 minutes qualifies
- B. Tooth 1 = Group 2, Tooth 2 = Group 2, Tooth 3 = Group 3 — wet towel is not a recognized storage medium and dry time exceeds 60 minutes
- C. Tooth 1 = Group 1 (HBSS is equivalent to replantation), Tooth 2 = Group 2, Tooth 3 = Group 2 (wet towel counts as storage)
- D. Tooth 1 = Group 2, Tooth 2 = Group 3 (25 minutes dry exceeds 30-minute viability), Tooth 3 = Group 3

Integration: (1) Group 2 = stored in medium + total dry <60min: Tooth 1 (HBSS, 3min dry ✓) and Tooth 2 (saliva, 25min dry ✓). (2) Group 3 = >60min dry regardless of medium: Tooth 3 (65min in wet towel — not a recognized medium, and total time >60). (3) 30-min PDL viability threshold ≠ 60-min group classification threshold.
