“…Diagnostic confirmation can only be ascertained after anatomic pathology examination. 13 According to Becconsall-Ryan et al, 12 inflammatory lesions corresponded to 72.8% of radiolucent lesions of the jaws. Among them, 29.2% were periapical cysts.…”

“…Therefore, because periapical cysts are less prone to heal after conventional endodontic therapy, surgical intervention is needed. 13 For the treatment of periapical cysts, enucleation is the most commonly used technique, 20 although Carrillo et al 19 performed cyst enucleation in combination with apicoectomy and retrograde filling. To achieve satisfactory periapical healing, surgical removal of a periapical cyst must include elimination of root canal infection.…”

Correlation between inflammatory infiltrate and epithelial lining in 214 cases of periapical cysts

et al. 2013

The aim of this study was to evaluate the prevalence of periapical cysts, identify their clinical and microscopic features and correlate their microscopic features with the inflammatory infiltrate present in the lesion site. A total of 214 cases were collected over a 10-year period. Clinical data, including gender, age, race, symptoms and location of the lesion, were recorded. Two independent examiners with no prior knowledge of the patients' clinical data conducted the microscopic evaluations. Statistical analyses were performed using Fisher's or chi-square tests at a 5% level of significance. The results showed that periapical cysts were more prevalent in white women, with a mean age of 35 years, and in the anterosuperior region. The majority of the lesions were lined by atrophic cystic epithelium, which was associated with moderate inflammatory infiltrate in the cystic capsule (p < 0.01), with a diffuse localization pattern (p = 0.03) and absence of neutrophils (p = 0.01). Our findings suggest that periapical cysts lined by atrophic epithelium are related to the presence of moderate mononuclear inflammatory infiltrate.

“…They also noted that bacterial bio lms of endodontic origin had formed between the layers of the apical cementum. In a separate study, Lin et al 14 focused on the histopathological assessment of nonsurgical root canal treatment cases with large, cyst-like periapical lesions. They noted that during periapical wound healing, cells from the remaining viable periodontal ligament in adjacent root surfaces had proliferated to cover the root surfaces where the periodontal ligament and surface cementum had been damaged by in ammation and removed by activated macrophages.…”

: This retrospective study used cone beam computed tomography CBCT to evaluate various radiographic prognostic indicators that affect the outcome of root canal retreatment. The study population was selected from consecutive patients examined in the endodontic department from June 1 to December 31, 2013. In total, data were collected for 143 patients mean age 47.7 years ; female : 89, male : 44 who underwent CBCT examination, including 276 roots with periapical radiographs of 158 teeth. CBCT images were re-interpreted independently by one oral radiologist for cases of periapical root resorption and periapical hypercementosis. Nonsurgical endodontic retreatment was indicated for 125 roots, and was subsequently performed by one of four certi ed endodontists. Each case was followed up and the prognosis was assessed in October 2014. Of 125 root canal-treated cases, 96 were deemed to have a satisfactory prognosis, 27 were considered questionable and 2 were considered unsatisfactory . In the 96 satisfactory cases, 15 showed periapical hypercementosis, and 51 showed periapical root resorption. The chi-squared test was used to analyze differences between groups. A value of P 0.05 was considered signi cant. There was a signi cant difference in the prognosis between the hypercementosis cases and the other groups. Several studies suggest that the presence of root resorption may worsen the prognosis of endodontic treatment. In this study, the presence of root resorption did not affect prognosis. This study provides evidence that CBCT is helpful in evaluating the prognosis of endodontic retreatment cases.

“…If the cyst does become large, symptoms such as swelling, mild sensitivity, tooth mobility and displacement may be observed. The affected tooth is nonresponsive to thermal and electrical pulp tests (Lin et al, 2009). RC can be treated with conservative endodontic therapy in small lesions, or combined with biopsy, marsupialization and enucleation (Martin, 2007).…”

Radicular cyst is the most common inflammatory jaw cystic lesion that occurs in necrotic teeth. They account for more than 50 % of all odontogenic cysts. Radicular cysts cause slowly progressive painless swelling and there are no symptoms until they become large. Enucleating the cyst with endodontic therapy of the affected tooth is recommended as the primary treatment. Here we describe a patient with a large recurrent radicular cyst with maxillary sinus involvement who underwent a midfacial degloving approach for complete enucleation. In conclusion, radicular cyst should be considered in the differential diagnosis of large maxillary sinus lesions and never be discarded until histopathology is available.
