A case of an odontogenic cutaneous sinus tract

Abstract

A 22-year-old female presented with a draining sinus tract on her left cheek. The tooth responsible was examined clinicopathologically. On clinical examination, the mandibular left first molar tooth was restored with an amalgam filling. Radiographic examination revealed base or pulp capping material below the restoration and a radiolucent periapical lesion surrounding the distal root apex. Conservative non-surgical root canal treatment was performed; 10 months later, the sinus had healed completely and the periapical lesion had resolved. Histopathological examination of pulp tissue recovered during treatment revealed foreign bodies, made up of capping material and amalgam, associated with chronic inflammation. These findings suggested that chronic inflammation in the pulp tissue had resulted in a draining sinus tract.

Submental cutaneous sinus tract of mandibular second molar origin

“…To make the correct diagnosis, obtaining the clinical and medical history, especially of any past episodes of dental pain, from the patient is important (Nakamura et al . ). Pulp tests and periradicular diagnostic testing should be performed on any suspected teeth and adjacent teeth (Gupta et al .…”

“…Some studies have suggested inserting a probe or an endodontic gutta‐percha point through the sinus tract to obtain radiographs so as to aid the identification of the affected teeth (Nakamura et al . , Pasternak‐Júnior et al . , Gupta et al .…”

“…Of these cases, the pathway through the buccal cortical plate towards the mandibular area is the most common (Nakamura et al . , Yasui et al . , Pasternak‐Júnior et al .…”

“…Radiographic findings are also important for the diagnosis and identification of affected teeth (Nakamura et al . , Abuabara et al . ).…”

Extraoral fistula: A case report

“…Fistülün intraoral veya ekstraoral bölgeye açılması dişin bulunduğu bölgeye, enflamasyon tarafından kortikal kemikte oluşan perforasyonun lokalizasyonuna bağ-lıdır. [1][2][3][4] Bakteriyel virülans, hastanın savunma mekanizması, fasiyal bölgedeki dokuların düşük direnci ve kas ataçmanları ile enfekte dişin ilişkisi de fistülün ilerleme miktarını ve yönü-nü etkilemektedir. Eğer dişlerin apikal kısımları maksiller kas bağlantılarının üstünde veya mandibuler kas bağlantılarının altındaysa enfeksiyon ekstraoral bölgeye doğru bir yayılma gösterebilmektedir.…”
