Brief Summary

The endodontic periodontal-disease is characterized by the involvement of the pulp and periodontal disease in the same tooth. The anatomic connections between the dental pulp and the periodontium provide a pathway for perio-endo communication via apical foramina, lateral canals, exposed dentinal tubules, and developmental grooves. These pathways provide an egress for pulpal disease to affect the periodontium and conversely, an ingress for periodontal disease to affect the pulp. Teeth with endo-perio disease, which are deemed salvageable might require root canal (endodontic) treatment, followed by staged periodontal treatment. Compared to conventional sealers used for endodontic treatment, the hydraulic calcium silicate based sealers (HCSB)s have excellent sealing ability, biocompatibility, regeneration ability, and antimicrobial characteristics. However little is known about its clinical benefits when used to treat endo-perio disease. The gold standard treatment for periodontitis affected teeth associated with intrabony lesions is guided tissue regeneration (GTR) which has significant improved clinical outcomes over open flap debridement (Cochrane systematic review 2005). However, the success the of this regenerative technique requires careful case and defect selection. We propose the use of an autologous bioactive scaffold, leukocyte platelet rich fibrin (L-PRF) to achieve regeneration of periodontal soft and hard tissues, resulting in faster healing, greater bone infill and improved predictability of clinical outcomes

Masking Details
Operators for endodontic - periodontal treatment will be different from the assessors for the initial assessments and subsequent review appointments. The Treatment will be masked for the patient and assessor. As the blood samples will be collected from the patients at T6 for biomarker analysis, therefore the patient can be masked about the treatment as these blood can be used for the LPRF treatment for those patient who are randomised in the LPRF group. The statistician will also be blinded to the allocations and will only conduct the analysis in a semi-blinded way (group 1 vs group 2 vs group 3 vs group 4) without knowing the corresponding groups until the analysis is complete.
