Abstract

Svrha ovog istraživanja bila je procijeniti stanje endodontski liječenih zuba koji su opskrbljeni fiksno-protetskim radom ili su bili pripremljeni za protetsku terapiju. Ispitanici i postupci: Analizirano je 300 ortopantomograma iz arhive Zavoda za fiksnu protetiku Stomatološkog fakulteta. Korišteni su ortopantomogrami pacijenata čiji su zubi nosači fiksno-protetskih radova već bili endodontski liječeni te ortopantomogrami pacijenata čiji su zubi bili endodontski pripremljeni za protetsku opskrbu. Prilikom analize ortopantomograma bilježena je udaljenost radiološkog apeksa zuba i završetka punila korijenskog kanala u milimetrima. Ovisno o izmjerenoj udaljenosti u milimetrima, punjenje je označeno kao prekratko, normalno ili kao prepunjenje. Također je određena i kvaliteta endodontskog punjenja te prisutnost periapikalnog procesa. Rezultati: Dužina endodontskog punjenja najčešće je bila prekratka kod donjih i gornjih kutnjaka. Endodontsko punjenje najčešće je bilo normalne dužine kod donjih sjekutića i donjih očnjaka. Prepunjenje korijenskih kanala uočeno je kod najviše donjih kutnjaka. Periapikalni proces najčešće je uočen kod endodontski liječenih donjih sjekutića i donjih kutnjaka, a najrjeđe je bio prisutan kod gornjih očnjaka te gornjih sjekutića. Uočeno je da su zubi koji su bili prekratko punjeni ujedno pokazivali i lošiju kvalitetu endodontskog punjenja. Nije uočena veza između nezadovoljavajuće dužine i kvalitete endodontskog punjenja te pojave periapikalnog procesa. Zaključak: Prekratka dužina endodontskog punjenja te lošija kvaliteta endodontskog punjenja češće su uočeni kod pretkutnjaka i kutnjaka negoli kod sjekutića i očnjaka. S obzirom na rezultate ovoga istraživanja, još uvijek je velik broj zuba koji nisu dobro endodontski izliječeni i time nisu kvalitetno pripremljeni za protetsku opskrbu.

Abstract (english)

The purpose of this research was to evaluate the condition of endodontically treated abutment teeth of fixed prosthodontics restauration or the ones which were prepared for fixed prosthodontics therapy. Methods: A total of 300 orthopantomograms from the archives of the Department of Fixed Prosthodontics of School of Dental Medicine were analyzed. The used orthopantomograms belong to the patients whose teeth had undergone endodontic treatment and already had a fixed prosthodontics restauration or were prepared for fixed prosthodontics therapy. During the analysis, the length of the root canal filling from the radiographic apex in millimeters was noted. Depending on the length in millimeters, the filling was labeled as too short, normal or overfilled. The quality of root canal filling and the presence of periapical lesions were also determined. Results: Too short length of the root canal filling was most commonly associated with maxillary and mandibular molars. Most often, from all the endodontically treated teeth, mandibular incisors and canines had a normal root canal filling length. Overfilling was most frequently detected in mandibular molars. Periapical lesion was most commonly detected in endodontically treated mandibular incisors and molars, but it was the rarest in maxillary canines and incisors. It was noticed that the teeth with too short root canal filling showed lower quality of the filling at the same time. The correlation between inadequate length and quality of the root canal filling and appearance of periapical lesion was not detected. Conclusion: Too short and poor-quality root canal fillings were found more often in premolars and molars, rather than incisors and canines. The results of this research show that there is still a large number of inadequately endodontically treated teeth that are not well prepared for fixed prosthodontics therapy.
