Sažetak
The aim of this study was to fallow-up periapical healing of the metod of recurrent electronic measurements. During ten years of endodontic practice of the firs author, endodontal interventions were performed on approximately 4500 patients, aged 12-75 years. The study included only those patients for whom a preoperative radiograph existed and follow-up radiographs during the investigated period. Thus the success of therapy was fallowed-up in 257 teeth with diagnosis K04.0 to K04.5 (X international classification of diseses). Root canal preparation started with "Crown-down pressureless technique" in the cervical and medium third of the canal. Apical extend of preparation ("working lenght") was measured by the own electronic method (device EED 11. Zagreb, Struja. Croatia) and was called length d1. At the length d1 foramen was enlarged to the diameter 3-4 times grated than initial, and electronic measurement repeated length d2. From that length started step-back preparation of the apical third. If this length was not confirmed by digito-tactile method before obturation. It was measured fr third time &#8211 ; length d3. Canals were always obturated to the apical constriction which was planed at the level 2 mm shorter that length d2 (foramen anatomicum), or the length d3 in the case of third measurement. We used gutta-percha - eucapercha method. Obturation was done at the first visit if the H-file no. 25 at the foramen anatomicum has found material of the bright red color. The sign is known in the bone surgery. If this sign was missing, the obturation was postponed for 7-12 days and the tooth temporarily closed with drainage. The result of therapy success was approximately 95% (t &#8211 ; test ANOVA &#8211 ; analysis of variance). For the diagnosis K04.1 &#8211 ; 64%. For the K04.4 &#8211 ; 88%. For the K04.0 and K04.2 &#8211 ; 95%. For the K04.5 &#8211 ; 98%. And K04.3 &#8211 ; 100%. We can conclude that the method of recurrent measurements detected layer of immunologically and biochemically changed tissue. This zone is situated approximately 1, 5-2, 5 mm beyond root apex. Removing of this irreversibly changed zone during endodontic preparation gives acceptable success of therapeutic results.
