Key result
Supportive periodontal therapy is linked to ~50% lower probing depth at 1 year post-flap surgery.
Why the study?
Supportive periodontal therapy (SPT) is used after active periodontal treatment to reduce re-infection and disease progression, but its long-term effectiveness after flap surgery requires assessment.
Cohort (n=100)
No
Absolute Event Rate: 1.01% vs 2%
p-value: p=0.001
May support maintenance after flap surgery; hypothesis-generating and requires RCTs before practice change.
Background: Periodontitis is a bacterially-induced, chronic inflammatory disease that destroys the connective tissues and bone that support teeth.Active periodontal thearapy aims to reduce the inflammatory response, primarily through eradication of bacterial deposits.Following completion of treatment and arrest of inflammation, supportive periodontal therapy (SPT) is employed to reduce the probability of re-infection and progression of the disease; to maintain teeth without pain, excessive mobility or persistent infection in the long term, and to prevent related oral diseases.Aim: The aim of the study is to assess the periodontal stability during maintenance period; effectiveness of SPT in long term follow up after flap surgery. Materials And Methods:A total of 100 subjects were included in this study.50 females and 50 males were included, divided into 2 groups.Group 1: Non-Maintenance Phase (n=50); Group 2: Maintenance Phase (n=50).The Clinical parameters assessed were : GI (Gingival Index), PI(Plaque Index), PD(Probing depth), CAL(Clinical attachment loss), Gingival Bleeding index,Tooth mobility, Tooth loss.The Parameters were assessed at Baseline, 1 month, 3 months, 6 months and 1 year.Statistical analysis were carried out by using SPSS software 23.0 Results: The present study discussed Group 1: Non-Maintenance Phase (n=50); Group 2: Maintenance Phase (n=50).The Clinical parameters assessed were : GI (Gingival Index), PI(Plaque Index), PD(Probing depth), CAL(Clinical attachment loss), Gingival Bleeding index,Tooth mobility, Tooth loss.The Parameters were assessed at Baseline, 1 month, 3 months, 6 months and 1 year.For Gingival index, Plaque index, Probing depth, Clinical attachment loss, Gingival bleeding index, Tooth mobility, Tooth loss: Group 1: Non-Maintenance Phase; Group 2: Maintenance Phase are not significant at baseline and 1 month follow up p>0.05; are significant at 3 months, 6 months and 1 year follow up.e93 Effectiveness of SPT in Long term follow up after flap surgery -1 year follow up study

A 2023 study conducted a cohort in Generalized chronic periodontitis (n=100). Supportive Periodontal Therapy (SPT) vs. Non-Maintenance Phase was evaluated on Probing depth at 1 year (p=0.001). Supportive periodontal therapy significantly reduced mean probing depth at 1 year compared to non-maintenance (1.01 mm vs 2.0 mm, p=0.001) following flap surgery.
