Prevalence of odontogenic sinus tracts in 728 endodontically treated teeth

Abstract

Objectives: The primary aim of this study was to assess the prevalence of sinus tracts in endodontically treated teeth in an Iranian population. The second aim was to seek and analyze the relationship between the clinically detected sinus tracts and factors such as sex, age, tooth type and location. Study design: A total of 728 patients` records and radiographs were reviewed of 427 females and 301 males for demographic data, preoperative pulpoperiapical status of treated teeth and the presence of sinus tract. Data were analyzed using chi-square test. Results: No significant differences were found for the prevalence of sinus tracts between two genders. Data showed that the highest prevalence of sinus tracts was in 10-19 year age group. Of 725 treated teeth, 107 teeth had sinus tracts (14.7%). Most odontogenic sinus tracts were associated with mandibular anterior teeth. Of 348 teeth with preoperative status of periapical inflammation and radiolucency, 107 teeth (30.75%) had an odontogenic sinus tract. Conclusion: Data showed that almost one in seven teeth referred for root canal treatment had a sinus tract.

“…A study published by Miri et al [13] which was realized in Iran in 1,527 patients with a personal history of endodontic treatment, it was found a frequency of a sinus tract of 9.9% in contrast with another study reported by Sadeghi et al [14] in 2011 in a very similar population with the same procedence and under canalicular therapy, in 728 patients it was set a prevalence of 14.7% [13,14] submitting the patient to unnecessary antibiotic treatments, biopsies, resections, and even radiotherapy, with a not so favorable outcome and a recurrence of the fistula [1][2][3]. Patients with or cutaneous fistulas it has been thought that odontocutaneous fistulas are more frequent in children and adolescents, due to the fact that the alveolar processes are not fully developed, although, it has been seen in patients older than 20 years of age [9].…”

“…The average of the patient age varies: Sadeghi et al [14] reported an age range of 10-69 years; in the Guevara et al [15] study the mean was 45 years with a higher presentation of sinus tracts in patients older than 51 years. In the Slutzky et al [16] the mean was 32.2 years [14,15]. According to gender, the presence of odontocutaneous fistulas can vary: Guevara et al [15] found 53% of women with this condition and Miri et al [13] in a 9.1% and Huang et al [17] in 45.3% of women, meanwhile; Sadeghi et al [14] did not find significant differences between men and woman [13][14][15][16][17].…”

“…Vicentii, orphyromonas gingivalis Veillonella parvula, Enterococcus faecalis, Campylobacter gracellis and Neisseria mucosa invade the tooth through the enamel and dentin, infecting the pulp causing necrosis, periodontitis and formation of the periapical abscess, rich in anaerobic bacteria. Usually this process is acute and renders the patient to seek medical attention [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. With the passing of time between six months and 30 years, added to the partial and temporal recovery, symptoms may be masked meanwhile the infectious process continues and intensifies, becoming chronic.…”
