Clinical Trial Summary
Evalaution of clinical success of secondary treatment for total 40 permanent incisors with
failed root canal treatment with apical radiolucency.
Twenty of of these permanent incisors will be treated with regenerative endodontic
treatment(RET) with platelets rich fibrin PRF as intervention group vs. 20 incisors control
group secondary treated with (RET) with induced blood clot (BC).
Description:
A preliminary randomized parallel controlled trial will be conducted. Forty teeth of 36
patients were randomly assigned into two groups: group "PRF", treated with RET with PRF
platelets rich fibrin (intervention), and group "BC", treated with RET with induced blood
clot(control). Upon clinical examination, the presence of pain on biting or percussion,
swelling or sinus tract, or abnormal tooth mobility will be considered a failure. To monitor
the changes in periapical radiolucency, a periapical index (PAI) will be used. The primary
outcome of the current study will be to assess the effectiveness of RET using PRF platelets
rich fibrin of mature permanent incisors with periapical radiolucency compared to RET using
induced BC formation in the root canal space.
Eligibility criteria:
Healthy adolescents below the age of 18 years who need endodontic retreatment of previously
obturated mature single-rooted incisors with gutta-percha will be recruited.
Patients with a positive history of allergic reactions, systemic diseases, and severe
emotional or behavioral problems will be precluded. Only teeth diagnosed with asymptomatic
apical periodontitis or chronic apical abscess (i.e. little discomfort with intermittent
episodes of pus discharge through the sinus tract) were included. To confirm the clinical
status, only teeth with a periapical index (PAI) score ≥3 based on Ørstavik et al
classification were considered. Teeth with previous attempts for endodontic retreatment
including pulpotomy or pulpectomy, non-restorable crowns or need post placement, or
periodontal problems were excluded. A tooth must not be a candidate for endodontic surgery
according to Glickman et al. indications and the updates of the European Society of
Endodontology (e.g. obtaining biopsy, removal of intracanal broken files, persistent
periapical lesions standing for a long period, radicular perforation, root fracture, or
obstructed root canals, or the inability of complete removal of old gutta-percha or extruded
material beyond the apex with persistent apical lesion for long duration).
Interventions:
According to the latest RET operating guidelines issued by the American Academy of
Endodontics (AAE) and the European Society of Endodontics (ESE), the standardised operating
procedure of RET requires two treatment visits. During the first appointment, infection is
controlled and inflammation is relieved with complete removal of failed obturation material.
Pulp regeneration and revascularization is accomplished during the second appointment.
