Evaluation of Liquorice Nanogel Versus Diode Laser as an Adjunctive Treatment for Patients With Periodontitis Stage Ⅲ. (Periodontology)

May 19, 2026 updated by: Alaa Yousri Mohamed, Al-Azhar University
Evaluation of the effect of liquorice nanogel versus diode laser on periodontitis stage Ⅲ clinically and microbiologically by molecular analysis of porphyromonas gingivalis using real time PCR.

Study Overview

Detailed Description

Quantitative analysis technique using real time pcr (polymerase chain reaction) was done to detect presence of porphyromonas gingivalis. Pocket depth (PD), Plaque index (PI), gingival index (GI) and Clinical attachment level (CAL) were measured before work and after 3 months postoperatively.

Analysis was made from gingival crevicular fluid samples of the patients using gutta percha paper points.
