Clinical evaluation of impact of periodontal phenotype on the outcome of open flap debridement in patients with chronic periodontitis: A comparative interventional study

Abstract

Background

A number of studies have implicated the role of periodontal phenotype (PP) in the outcome of various periodontal interventions. However investigations have not been performed to estimate such impact on the outcome of open flap debridement (OFD) for the management of chronic periodontitis.

Methods

73 individuals with chronic periodontitis underwent scaling and root planing (SRP). 8 weeks following SRP, modified Widman flap (MWF) surgery was performed in 40 patients (20 of either PP) presenting with probing depth (PD) ≥4 mm and gingival index (GI) ≥1 at ≥4 sites distributed over ≥2 anterior teeth with radiographic evidence of horizontal bone loss. PD, clinical attachment level (CAL), gingival recession, plaque index, GI and bleeding on probing (BOP) were recorded at baseline, 3 and 6 months. PP was assessed using transparency of periodontal probe through the gingival margin at midfacial level.

Results

34 patients were re‐evaluated after intervention. All periodontal parameters improved in both groups after periodontal surgery. PD & PP were found to have positive correlation with CAL gain in ≥7 mm probing sites. Attachment gain of >2 mm was observed in more percentage of sites in thick PP than in thin PP.

Conclusion

PP can be an important factor influencing CAL gain in OFD.

  1. I was born epileptic and at the same time I was having gastro disorder, but I am now free and cured by Dr Itua Herbal Made Medicine. I was seventeen and sitting at my computer when I fell out of my chair. Only thing I remember is waking up with the worst headache I had ever had in my life. I had never taken medication and I hated swallowing pills but I had to start. I switched between all kinds of medication because I didn't take them like I was supposed to. One day I had just finished running errands and was at my sister's house when I fell to the floor again. I woke up with a bad headache and my 2 year old Niece leaning over my leg asking me if I was OK. By then I had just started college and was one the verge of losing my license. My school is an hour away from where I live so I really got set back because I wasn't allowed to drive until I got my seizures under control. I would love to know how others have handled their epilepsy! So My sister's friend Emma Told my sister about a herbal Doctor who resides in west Africa(Nigeria) Because Emma is from Africa as well, My sister told me about it then we decided to give it a try. My sister contacted him also tell him about my autism too.he assures my sister that his herbal medicine will cure my epilepsy and my autism, I paid for the herbal medicine then he delivered to Charleston Post office I was called to pick it up which i quickly did, I drank it for two weeks as prescribed happily I went for diagnose and find out my Epilepsy and Autism is gone and today making it 9 Months and I'm now free from Autism, Seizure and Epilepsy, I will continue to share Dr Itua Natural Herbal Medicine works.
