About

This is a surgical comparative clinical trial which aims to assess class II buccal furcation defects treated with Xenograft alone or preceded by antimicrobial photodynamic therapy.

Full description

To test the efficacy of photodynamic therapy (Indocyanine green) along with placement of xenograft (Cerabone®-Natural bovine bone grafting material, Botiss biomaterials) to treat a class II furcation defects. The topical study was designed as a randomized controlled, single blinded (patient), split mouth clinical trial with 14 participants. In the control group, the defects were filled with xenograft (Cerabone®) whereas the test group received photodynamic therapy (Indocyanine green) in addition to grafting. Radiovisiography technique was used to observe the possible changes in the furcation region at baseline and 9 months postoperatively.

Experimental group

Description:

After debridement photodynamic therapy was performed by applying indocyanine green photo sensitizer to furcation defect sites for 1 min. A diode laser with the wavelength of 810 nm and 100 mW 0f power output in the continuous mode was applied to this site. The indocyanine dye has high absorption in the infrared spectrum with an absorption peak near 810 nm, which is close to the emission of diode lasers. This dye has low toxicity, a rapid elimination time and is a good photo sensitizer. The furcation defects then received the graft hydrated with sterile saline. The graft material compacted into the bone defect was similar to the control site.

Treatment:

Procedure: Open flap debridement and photodynamic therapy
