Popis: The bifid mandibular canal (BMC) is an anatomical variation with reported prevalence ranging from 0.08 to 65%. Identifying anatomical variations of mandibular canal is very important in order to prevent possible complications during oral surgical and other dental procedures. Objectives: The aim of this study was to determine the prevalence and to classify the morphology of BMCs using digital panoramic radiographs. Material and methods: A retrospective study was conducted that included 1008 digital panoramic radiographs (412 female and 596 male) used to identify the type of BMC. Panoramic radiographs were analyzed by three oral surgeons and one dentist, and BMCs were classified into six different types, 4 types according to Langlais et al. (types 1-4), and two new types (types 5 and 6) described by authors. Results: The prevalence of BMC was 4.66% (n=47), with no significant differences in gender between BMC types (P=0.947; χ2=0.74). The prevalence of type 1 BMC was 0.79 % (n=8), type 2 2.08 % (n=21), type 3 0.30 % (n=3), type 4 0% (n=0), type 5 0.89 % (n=9) and type 6 0.60% (n=6). Conclusion: This study revealed a relatively high prevalence of BMCs among Zagreb citizens. Furthermore, two new types of BMCs were described. These results stress the importance of a careful and thorough radiographic analysis prior to each invasive procedure in the mandible.
Dvostruki mandibularni kanal (DMK) anatomska je varijacija s učestalošću u rasponu od 0,08 do 65 %. Njegovo uočavanje iznimno je važno kako bi se prevenirale moguće komplikacije tijekom oralnokirurških i drugih dentalnih zahvata. Svrha: Cilj istraživanja bio je ustanoviti morfološke klasifikacije i učestalost dvostrukoga mandibularnog kanala koristeći se ortopantomogramskim snimkama. Materijali i metode: Obavljena je retrospektivna analiza 1008 digitalnih ortopantomograma (412 od žena i 596 od muškaraca) kako bi se identificirao tip i učestalost DMK-a. Tri oralna kirurga i jedan stomatolog analizirali su ortopantomogramske snimke i dvostruki mandibularni kanal klasificirali su u šest različitih tipova – četiri prema Langlaisu i suradnicima (tipovi 1 4) i dva nova (tip 5 i 6) koje su opisali autori ovoga istraživanja. Rezultati : Učestalost DMK bila je 4,66 % (n = 47), bez statistički značajne razlike prema spolovima (P = 0,947; χ2= 0,74). Učestalost tipa 1 iznosila je 0,79 % (n = 8), tipa 2 bila je 2,08 % (n = 21), tipa 3 – 0,30 % (n = 3), tipa 4 – 0 % (n = 0), tipa 5 – 0,89 % (n = 9) i tipa 6 – 0,60 % (n = 6). Zaključak: U ovom istraživanju utvrdili smo razmjerno visoku učestalost DMK-a među stanovnicima Zagreba. Nadalje, opisana su i dva nova tipa. Rezultati istraživanja pokazuju koliko je važna temeljita i temeljita analiza ortopantomograma prije svakoga invazivnog zahvata na donjoj čeljusti.
