Results (Study Ill)
Excavation trial
314 patients were randomized. The stepwise excavation group had a significantly
higher success rate (74.1%) at 1-year follow-up (median 476.5 days) compared with
the direct complete excavation group (62.4%) (P = 0.044). The pulp was exposed in
25 teeth (17.5%) after stepwise excavation and in 43 teeth (28.9%) after direct
complete excavation (Table 2).

Prognostic factors
Patients with pretreatment pain were significantly less likely to show a successful
treatment result at follow-up compared to those without pain, when adjusting for the
effect of treatment, age, and centre. Treatment of patients younger than 50 years
(median for the group: 28 years) was more likely to result in sustained pulp vitality
without apical radiolucency than following treatment of older patients (median age of
the group: 58 years); however, only borderline significance was noted. The odds
ratios of pulp exposure differed among the centres, with centres 1 and 2 significantly
more often avoiding pulp exposure (adjusted for the effect of treatment, age and
pain).
