Endodontic treatment of lower molar in a patient with paraesthesia of inferior alveolar nerve: A case report

Root canal (endodontic) treatment is demanding and complex procedure. A variety of difficulties can occur in different phases of endodontic procedure. Complex anatomorphological tooth structure, curved canals, close proximity of lower molars and premolars to inferior alveolar nerve make endodontic treatment even more challenging. During endodontic treatment, an inferior alveolar nerve may become traumatized and symptoms may vary from mild neurosensory dysfunction to a complete loss of sensation in the innervation area of damaged nerve. The aim of this paper is to present a clinical case of endodontic treatment of lower second molar with C-shaped root canal in a patient with paraesthesia of inferior alveolar nerve due to endodontic origin.
Endodontska terapija kanala korena zuba je težak i kompleksan zahvat, pa su zato česti i problemi u različitim fazama endodontskog postupka. Komplikovana anatomomorfološka struktura zuba, povijenost kanala, blizak odnos donjih molara i premolara i alveolarnog nerva dodatno komplikuje endodontsku proceduru. Tokom realizacije endodontske terapije može doći do traume donjeg alveolarnog nerva, a simptomi oštećenja alveolarnog nerva mogu da variraju od blage neurosenzorne disfunkcije do potpunog gubitka senzacija u predelu inervacionog područja oštećenog nerva. Cilj ovog rada je bio da se na jednom slučaju iz kliničke prakse predstavi endodontski postupak lečenja kanala korena donjeg drugog molara, karakterističnog c-oblika, kod pacijenta sa parestezijom donjeg alveolarnog nerva endodontskog porekla.
