The scope of the investigation was a comparative study between the classical surgical techniques applied in the treatment of chronic periodontitis and the adjuvant laser therapy.
Materials and method. The study was performed on a batch of 20 patients diagnosed with progressive chronic periodontitis, subjected to the classical surgical treatment – namely flap intervention in an operative field – versus a group of 18 patients with the same diagnosis, in whose case the surgical intervention was combined with ND-YAG laser phototherapy.
Results and discussion. Chronic periodontites appear as morbid entities with plurifactorial, both local and general, usually complex causes. As all patients under analysis suffered from an advanced stage of the disease, flap intervention was practised. However, utilization of laser as an additional technique of periodontal surgery gave better results. In advanced stages of the disease, the only viable alternative remains the surgical removal of the granulation and osteitic tissue from the periodontal pockets, elimination of the abnormal gingival proliferations, in parallels with a harmonious reinsertion of the gingival festoon.
Conclusions. Clinical investigations demonstrated that, in spite of the similar results registered in certain cases, a more rapid healing was noticed through laser utilization, as due to the vasodilatation produced at the level of microvascularization and to stimulation of neovascularization, and reduction of oedema in the affected zone.
