Brief summary

AIM: This prospective clinical study aimed to evaluate the efficacy of two distinct non-surgical periodontal therapy modalities in patients diagnosed with Stage 1 and Stage 2 periodontitis. METHOD: The study comprised 80 nonsmoking, systemically healthy volunteers. Patients were divided into two groups at random: the Guided Biofilm Therapy (GBT) group and the convetional therapy group, which included Gracey curette and an ultrasonic device. All patients were assessed before and one and three months after therapy for clinical characteristics like pocket depth, Gingival Index (GI), Plaque Index (PI), Bleeding on Probing Index (BOP), and the levels of IL-1β, IL-10, TNF-α, and MMP-8 in gingival crevicular fluid (GCF). RESULTS: ... CONCLUSION:...

Design outcomes

Primary

MeasureTime frameDescription
Gingival indexbaselineAll teeth are evaluated on 4 surfaces (distal, buccal, mesial, lingual) and the average is calculated. 0= Normal gingiva 1. Mild inflammation - minor color change, minor edema. No bleeding after probing. 2. Moderate inflammation - redness, edema and shine. Bleeding after probing. 3. Severe inflammation - significant redness and edema. Ulceration. Spontaneous bleeding tendency.
IL-1βbaselineA single specialist physician took GCF measurements at baseline, one month, and three months from the tooth with the deepest pocket identified at baseline before treatment in patients with periodontitis. In short, the region was isolated using cotton pads, and the plaque was removed using cotton pellets. After that, 20 cm of mild air drying was applied. Strips of absorbent paper (Periopaper®, Proflow Inc., Amityville, NY, USA) were used to obtain GCF samples. The strips were positioned for 30 seconds after being carefully inserted into the gingival sulcus/periodontal pocket until a small amount of resistance was felt. Strips tainted with blood were thrown away. Before being used for laboratory testing, each subject's strips were gathered, combined, and kept at -80 °C (Ultra Low-Temperature Freezer, New Brunswick Scientific). As directed by the manufacturer, enzyme-linked immunosorbent assay (ELISA) kits were used to measure the levels of IL-1β, TNF-alpha, IL-10, and MMP-8 in GCF
