Detailed Description
Periapical surgery is a viable treatment option in teeth with persistent apical periodontitis, especially in cases which fail to heal by non surgical treatment. Kim and Kratchman classified periradicular lesions into categories A-F. Lesions A-C are of endodontic origin without any periodontal pockets and vary with respect to the size of periapical radiolucency while D-F are combined endodontic - periodontal origin and are ranked accoding to the magnitude of periodontal breakdown. Type F defects are commonly referred to as apicomarginal defects and have worst prognosis among all. The lower success rate is attributed to the apical migration of junctional epithelium and intrusion of non osteogenic connective tissue into the periapical region.
Various resorbable and non resorbable collagen membrane with or without xenograft, allograft and alloplastic materials have been used in different studies. Although animal studies have reported high success rates with the use of bone graft materials and membranes over the controls but no human study till date has evaluated or compared the effect of using an allograft and membrane versus Control.
Thus, the aim of the present study is to investigate to two hypothesis. The first null hypothesis stated that there would be no difference between quality of life and healing outcome of periapical defects with periodontal communications following surgery using membrane with allograft and the conventional control group utilizing no GTR technique. The second null hypothesis stated that there would be no difference in outcome derived from the assessment of 2D periapical radiographs and 3D CBCT imaging.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
|---|---|
|
Experimental: Periapical surgery with placement of an allograft and a membrane
Patients will undergo periapical surgery and an allograft and a membrane will be placed inside the bony crypt and over the denuded root surface respectively before closure of the flap.
|
Periapical surgery will be done followed by placement of an allograft into the defect and a membrane over the defect before closure of the flap.
|
|
No Intervention: Periapical surgery with no placement of any graft or membrane
Patients will undergo periapical surgery with no placement of any graft or membrane in the control group.

Primary Outcome Measures

Measure Description |
Time Frame |
|---|---|---|
|
Healing of apicomarginal defects.
Time Frame: Baseline to 12 months
|
Patients will be checked clinically for absence of signs and symptoms. Radiographic 2D assessment will be done by Rud and Molven criteria as follows:- Complete healing- defined by re-establishment of the lamina dura Incomplete healing (scar tissue) Uncertain healing Unsatisfactory healing (failure). 3D healing will be assessed by modified PENN 3D criteria(Schloss et al) as- Complete healing Limited healing Uncertain healing Unsatisfactory healing. |
Baseline to 12 months

|
All patients will be given a questionnaire (Igor Tsesis et al) with 15 questions to evaluate their quality of life for 7 days postsurgery.
