Outcomes of Periodontal Regenerative Treatment

Short & Medium Term Outcomes of Periodontal Regenerative Procedures. A Two-part Study With a) Analysis of Periodontal Records of a Cohort of Periodontitis Patients and b) a Single Visit Recall and Comprehensive Periodontal Re-evaluation

The aim of this recall study is to evaluate outcomes of surgical regenerative treatment of periodontal defects in a cohort of patient previously treated for gum disease at the Royal London Hospital as part of their periodontal care.

This study will be divided in two parts:

Part 1: a retrospective analysis of short-term outcomes of periodontal regenerative procedures undertaken at the Barts Royal London Dental Hospital (RLDH); Part 2: a single recall visit study in which patients identified through part 1 and willing to consent for the study will be reassessed for medium-term outcomes of the regenerative procedures previously undertaken.

For part 1 historic data will be collected from available dental records at RLDH and divided in:

• Timepoint 0: the latest available full mouth periodontal assessment before surgery and x-ray of site/s needing surgical intervention
• Timepoint 1: the latest available full mouth periodontal assessment after surgery and x-ray of same site/s at Timepoint 0

For part 2 data will be collected from patients identified through part 1 and willing to give consent for a single study recall visit:

•Timepoint 2: single study outcome recall visit (full mouth periodontal assessment and x-ray of same site/s at Timepoint 0).

Due to the nature of the study, the time elapsed between Timepoint 0 and Timepoint 2 can vary between 1 and 4 years.
