Effects of Local and Systemic Metronidazole as Adjunctive Treatment in Chronic Periodontitis Patients.

Objectives: This study aimed to compare the effects of local and systemic metronidazole in patients with chronic periodontitis.

Materials And Methods: In this randomized clinical study, 30 patients (3 teeth per patient) were treated in three groups: scaling and root planing (SRP) treatment alone, metronidazole tablet as adjunctive treatment, and metronidazole gel as adjunctive treatment. BOP (bleeding on probing), PPD (pocket probing depth), and CAL (clinical attachment level) data were collected at the beginning and 3 months later.

Development of a full-scale wastewater treatment plant for licorice root processing factories: A hybrid biodegradation-lime-alum-ozonation process.

Liquorice is a perennial legume that grows principally in Asia, the Middle East and some parts of Europe. The sweet root extract is mainly used in the pharmaceutical, food and confectionary industries. It contains 400 compounds, including triterpene saponins and flavonoids, which are responsible for liquorice's bioactivities.

Comparing the effect of preparation of the implant sites with piezosurgery and conventional drilling on the stability of implants at 5-months follow-up.

The objective of this study was to compare the effects of preparing for implant site osteotomy with conventional drilling or piezosurgery on the stability of oral implants after a 5 month follow-up period. Thirty patients participated in this randomized clinical trial and received two implants in posterior mandible in bone of the same quality. All surgical procedures were performed by the same surgeon.

Efficacy of Application of Platelet-Rich Fibrin for Improvement of Implant Stability: A Clinical Trial.

Use of platelet concentrates to increase implant stability, due to their regenerative potential, has recently attracted the attention of researchers. This study aimed to assess the effect of platelet-rich fibrin (PRF) on dental implant stability. This clinical trial evaluated 10 patients who received 50 dental implants.

Sonochemical synthesis and characterization of new seven coordinated zinc, cadmium and mercury nitrate complexes: New precursors for nanostructure metal oxides.

The nitrate complexes of group 12 elements with a tridentate Schiff base ligand (L = (E)-N1-((E)-3- phenylallylidene)-N2-(2-((E)-((E)-3-phenylallylidene) amino)ethyl) ethane-1,2-diamine) were synthesized via sonochemical process and characterized by various physical and chemical methods. The structural analysis of the zinc nitrate complex by single crystal X-ray diffraction analysis shows that the central atom is seven-coordinated by three nitrogen atoms from the Schiff base ligand as well as four oxygen atoms from two different nitrate anions. The geometry around the metal center can be described as a distorted pentagonal bipyramid.
