Objective: The main purpose of this study was to evaluate pain symptoms in patients after endodontic treatment performed in a single session in teeth with vitality or pulp necrosis, comparing two depths of insertion of the NaviTip irrigation needle.
Materials And Methods: One-hundred upper uniradicular teeth were selected and divided into four groups ( = 25), namely Bio group 1 (live pulp/1 mm from the foramen), Bio group 3 (live pulp/3 mm from the foramen), Necro group 1 (pulp necrosis/1 mm from the foramen), and Necro group 3 (pulp necrosis/3 mm from the foramen). All canals were instrumented with Wave One Gold System. Irrigation was performed using 2.5% NaOCl. The teeth were filled using the single-cone technique with AH Plus sealer using a McSpadden compactor. After treatment, patients answered a questionnaire with a visual analog scale scored from 0 to 10 at 1, 3, and 7 days after treatment.
Statistical Analysis: Data were analyzed using Mann-Whitney U, Wilcoxon, and Friedman tests.
Results: There was a decrease in average pain levels at the three time points for both vital and necrotic teeth ( < 0.05). There were no significant differences in postoperative pain levels comparing needle depth, or vitality and pulp necrosis ( > 0.05). The percentage of mild pain increased over time and moderate pain decreased, regardless of pulp condition. There was no incidence of acute pain at any time.
Conclusions: Post-treatment endodontic pain levels in upper uniradicular teeth with or without pulp vitality resulted in similar pain scores, regardless of the depth of insertion of the irrigation needle in relation to the apical foramen.

Purpose: We performed a pragmatic, cluster randomized controlled trial of a comprehensive practice-level, multistage practice transformation intervention aiming to increase behavioral health integration in primary care practices and improve patient outcomes. We examined associations between completion of intervention stages and patient outcomes across a heterogeneous national sample of primary care practices.
Methods: Forty-two primary care practices across the United States with colocated behavioral health and 2,945 patients with multiple chronic medical and behavioral health conditions completed surveys at baseline, midpoint, and 2-year follow-up.
