Bilateral üç kök ve üç kanallı maksiller küçük azılar: Olgu sunumu

Maksiller küçük azılar, özellikle birinci küçük azılar genelde iki kanala sahiptirler. Fakat yapılan çalışmalar, nadir olarak üç kanala sahip olduklarını göstermektedir. Konvansiyonel radyografi, çok köklü dişler ve değişik kök kanal morfolojisine sahip dişlerde tedavinin başarılı olması için yeterli bilgiyi veremeyebilir. Bu sebeple, tedavi öncesi dişlerin nadir de olsa değişik kanal formlarına sahip olabileceği akılda tutulmalıdır. Gerekli görülürse daha ideal bir tedavi ve başarı için, ileri görüntüleme tekniklerinden yardım alınmalıdır. Bu vaka raporunun amacı, gömülü kanin dişlerinin lokalizasyonlarını tespit etmek için dental tomografisi alınmış bir hastada tesadüf eseri saptanan bilateral üç köklü maksiller üst küçük azı dişlerinin radyografik görüntüleri eşliğinde, endodontik tedavi öncesinde doğru radyografik ve klinik muayenenin öneminin vurgulanmasıdır.

Bilateral maxillary premolars with three roots and three canals: Case report

Maxillary premolars, especially first premolars usually have two root canals. Although studies have showed that they may rarely have three canals. Conventional radiography cannot be adequate to give information for successful treatment of teeth, which have multi-roots and different canal morphology. Therefore, prior to treatment, although it is rare, it should be in mind that teeth canals may have different forms. If it is necessary, advanced imaging techniques can be performed for ideal treatment and success. The aim of this case report is to emphasize the importance of correct radiographic and clinical examination prior to endodontic treatment with the incidental radiographic images of bilateral three-rooted maxillary first and second premolars of a patient who was performed dental tomography to localize the impacted canines.
