Abstract
Trepanacijski otvor (pristupni kavitet) izrađuje se na površini krune zuba, a njime se prikazuje unutrašnjost, tj. endodontski prostor zuba. Slijedeći koncept minimalno invazivne endodoncije, trepanacijski otvor nastoji se izraditi s težnjom maksimalnog očuvanja tvrdog zubnog tkiva. Glavna pretpostavka je da će očuvanjem većeg volumena zubne strukture, endodontski liječeni zub biti otporniji da žvačne sile te se smanjiti mogućnost frakture. Ne postoji jedinstvena klasifikacija minimalno invazivnih trepanacijskih kaviteta. Američko endodontsko udruženje (engl. American Association of Endodontology) i Europsko endodontsko društvo (engl. European Society of Endodontology) predložili su dvije slične podjele, a razlikuju se u nazivima, dizajnima i dimenzijama kaviteta. Glavni cilj svih zagovaratelja minimalno invazivnog pristupa je očuvati što je više moguće zubne strukture, na žalost takvi smanjeni trepanacijski otvori povećavaju rizik od grešaka zbog smanjenja vidljivosti i otežanog pristupa korijenskim kanalima. Kompromitirano je čišćenje korijenskih kanala te se mora koristiti dodatan instrumentarij kako bi dezinfekcija bila zadovoljavajuća. Osim navedenog, otežan je i postupak revizije. Zahtjeva dodatno vrijeme i poseban instrumentarij. Smanjenjem vidljivosti prilikom instrumentacije, pojavljuju se i intrakanalne greške kao što je transportacija. Uz navedeno, veličina trepanacijskog kaviteta određuje i otpornost zuba na okluzijska opterećenja i pojavu fraktura. Smanjenjem dimenzija pristupnog kaviteta, otežano je i pravilno čišćenje kaviteta nakon punjenja korijenskih kanala. Dosadašnja istraživanja nisu dokazala kliničke prednosti minimalno invazivnih trepanacijskih kaviteta pa još uvijek nisu pronašli svoju primjenu u svakodnevnoj kliničkoj praksi.
Abstract (english)
The access cavity is made on the occlusal surface of the tooth's crown to provide access to its interior, specifically the endodontic space. Following the concept of minimally invasive endodontics, the access cavity aims to perserve maximum hard tissue. The main assumption is that by preserving more tooth structure, endodontically treated teeth will be more resistant to masticatory forces, reducing the risk of fractures. Currently, there is no official classification for minimally invasive access cavities. The American Association of Endodontology and European Society of Endodontology have proposed two similar classifications, which differ in names, designs and cavity dimensions. The primary objective of all advocates of the minimally invasive approach is to retain as much tooth structure as possible. Unfortunately, such reduced trepanation increases the risk of errors due to limited visibility and challenging access to the root canals. This compromises the cleaning of the root canals, necessitating the use of additional instruments for satisfactory disinfection. In addition, retreatment becomes more difficult, time-consuming and it requires special instruments. Reduced visibility during intrumentation, also leads to an increased occurrence of errors, such as canal transportation. Additionally, the size of the cavity also determines the tooth's resistance to occlusal loads and the likelihood of fractures. By reducing the dimensions of the access cavity, also makes proper cleaning of the cavity after root canal filling more difficult. Previous research has not yet provided sufficient clinical advantages of minimally invasive access cavities, which is why they have yet to be widely implemented in everyday clinical practice.
