Inflammatory follicular cysts associated to necrotic primary teeth.

BACKGROUND

Cysts are pathological cavities lined by epithelium and supported by connective tissue, containing fluid or semi-fluid substances and presenting developmental or inflammatory origins.

CASE REPORT

This study aimed to evaluate a case series of inflammatory follicular cysts in children to clarify their nomenclature, diagnosis, clinical implications and treatment outcomes. Prevalence, aetio-pathogenesis, clinical, radiographic and microscopic findings, treatments and sequelae of this condition were assessed by using the records of patients treated between 2000 and 2015. Data were analysed and presented descriptively.

FOLLOW-UP: This was performed periodically for 2 years to monitor lesion regression and complete eruption of impacted permanent teeth. All of the involved permanent teeth erupted naturally. Twelve cases of asymptomatic lesions with volumetric bone expansion were identified through radiographic findings or delayed tooth eruption in patients aged between 8 and 14 years. After establishing the diagnosis of inflammatory follicular cyst, necrotic primary teeth extraction was followed by decompression of the cystic lesions.

CONCLUSIONS

The investigated cases were consistent with inflammatory follicular cyst diagnoses. The proposed treatment was considered to be appropriate, that was revealed by the maintenance of the permanent teeth involved during the patients follow-up.
