Brief summary

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.

Detailed description

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.

Inclusion criteria

Inclusion criteria for part 1 of the study: * Patient age 18 and older * Patients that received periodontal regenerative surgical treatment at Barts RLDH from January 2017 to January 2019 with and without the use of any biomaterials, bone graft/substitute and membrane or combinations of those. * Available full periodontal examination records after non surgical therapy to serve as a baseline for the study and not beyond 12 months before surgery * Available radiographic examination of the tooth treated with surgical regenerative procedure at initial examination or after non surgical therapy to serve as a baseline for the study. Additional inclusion criteria for part 2: -Patient able and willing to give informed consent

Design outcomes

Primary

MeasureTime frameDescription
% of patients with pocket closure at worst site per mouth for intrabony defectsThrough study completion, an average of 2 yearsPocket closure is defined as PPD \< and = 4 mm with no bleeding on probing (BoP)

Secondary

MeasureTime frameDescription
% of patients with pocket closure at worst site per mouth for intrabony defectsMeasured at Timepoint 1 (from 6 months up to 1 year)Secondary outcome

Changes in clinical attachment level (CAL) for intrabony defects at site and patient level.Changes measured from baseline (Timepoint 0) to Timepoint 1( from 6 months up to 1 year) and Timepoint 2 (through study completion, an average of 2 years)Secondary outcome
Changes in horizontal furcation involvementChanges measured from baseline (Timepoint 0) to Timepoint 1( from 6 months up to 1 year) and Timepoint 2 (through study completion, an average of 2 years)Secondary outcome
Changes in vertical CAL for furcation defectsChanges measured from baseline (Timepoint 0) to Timepoint 1( from 6 months up to 1 year) and Timepoint 2 (through study completion, an average of 2 years)Secondary outcome
Change in diagnosis of periodontal diseaseChanges measured from baseline (Timepoint 0) to Timepoint 1( from 6 months up to 1 year) and Timepoint 2 (through study completion, an average of 2 years)Secondary outcome
Radiographic bone levels changes at site levelChanges measured from baseline (Timepoint 0) to Timepoint 1( from 6 months up to 1 year) and Timepoint 2 (through study completion, an average of 2 years)Secondary outcome
