Abstract
At the present stage of development of therapeutic dentistry it is necessary to study the usage of temporary obturation, itsprolonged antiseptic effect on the periapical tissue and root canal. The effect of laser radiation in combination with its unique properties can be used for selective inhibition of pathogenic organisms, sensitized drugs that are activated by laser light at low power. This property of lasers underlying method photo-activated disinfection of root canals (PAD). Learning of opportunities of PAD and temporary root canal obturation influence to the clinical course of chronic periodontitis are urgent issues of modern endodontics.
Were examined and treated 70 people who were diagnosed with chronic chronic apical periodontitis. Depending on the chosen method of treatment was determined four groups of patients -three main and one control. The treatment was carried out at constant X-ray control.
The first group consisted of 18 patients. In addition to standard methods of dental treatment root canal was included stage of temporary obturation. The second major group consisted of 16 people. In addition endodontic treatment of root canal irrigation instead of the standard protocol to plan the treatment of chronic apical periodontitis was used PAD, after which permanent obturation performed in one visit. The third study group comprised 17 patients. Standard treatment protocol consisted of endodontic treatment, PAD with 10% povidone-iodine solution, the stage of temporary obturation with paste based on calcium hydroxide for 10 days, permanent obturation by lateral condensation of cold gutta-percha, applying sealers based on epoxy resins. The control group consisted of 19 people. Treatment protocol included the endodontic root canal treatment with standard protocol constant irrigation and permanent obturation in one visit.
According to the guidelines of the European Society endodontology (ESE, European Society of Endodontology, 1994) to assess the quality of treatment of chronic apical periodontitis used performance categories:
Category 1 — «Full recovery» or «success»: the absence of clinical symptoms (pain, swelling, occurrence of fistulas, pain with palpation or percussion), saving function and determined radiographically normal state periodontal gap (radiographic signs of bone regeneration);
Category 2 — «Partial recovery»: the absence of clinical symptoms and reduce X-ray revealed the source of destruction of bone periapical area;
Category 3 — «The failure»: lack of pronounced clinical symptoms in X-ray output intact apical periodontal pathology;
Category 4 — «The lack of recovery»: the presence of clinical symptoms of chronic periodontitis patient complaints, no radiographic evidence of periapical lesions or the formation of new periodontal riding.
Evaluation of clinical parameters was performed before treatment, after the permanent obturation, 6 and 12 months after treatment.
The higher number of complications at various stages has been noted in the second and the control group where the treatment of chronic apical periodontitis conducted with tools, drug treatment and permanent obturation of root canals in one visit.
The most successful clinical performance in all stages of treatment were observed in the third group, which was used in combination PAD and temporary root canal obturation. Tion in the group, none of the study participants did not have clinical complaints and 12 months after treatment in 88.2% of patients had marked the fourth category of treatment effectiveness periodontitis «Success».
None of the study participants were registered third and fourth category of treatment effectiveness «The failure» and «lack of recovery».
