Clinical Trial Summary

The purpose of this randomized controlled clinical trial was to evaluate two dimensionally and 3-dimensionally the effect of resorbable collagen-based bone filling material on periapical healing following endodontic microsurgery (EMS) on endodontic lesions presenting four-wall defect.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	2D Radiographic Healing at 12 Months Follow up (Overall Cases)	Periapical healing was assessed by qualitatively evaluating bone regeneration through PA radiographs using well-established criteria. Molven's criteria categorize healing using periapical films into four categories: complete healing, incomplete healing, uncertain and unsatisfactory healing.	12 months
Primary	3D Radiographic Healing at 12 Months Follow up (Overall Cases)	Periapical healing was assessed by qualitatively evaluating bone regeneration through CBCT scans using Penn 3D criteria. Cases were classified into complete, limited, or unsatisfactory healing.	12 months
Primary	2D Radiographic Healing at 12 Months Follow up (Asymptomatic Cases Only)	Periapical healing was assessed by qualitatively evaluating bone regeneration through PA radiographs using well-established criteria. Molven's criteria categorize healing using periapical films into four categories: complete healing, incomplete healing, uncertain and unsatisfactory healing.	12 months
Primary	3D Radiographic Healing at 12 Months Follow up (Asymptomatic Cases Only)	Periapical healing was assessed by qualitatively evaluating bone regeneration through CBCT scans using Penn 3D criteria. Cases were classified into complete, limited, or unsatisfactory healing	12 months
Secondary	C Score (Overall Cases)	Cortical plate healing using RAC/B index as evaluated on CBCT scans.; Score 0: Cortical plate not re-established (Nonhealed). Score 1: Cortical plate is partially re-established (Partially healed). Score 2: Cortical plate is re-established (Completely healed).	12 months
Secondary	C Score (Asymptomatic Cases Only)	Cortical plate healing using RAC/B index as evaluated on CBCT scans.; Score 0: Cortical plate not re-established (Nonhealed). Score 1: Cortical plate is partially re-established (Partially healed). Score 2: Cortical plate is re-established (Completely healed).	12 months
