Treatment of Maxillary Inflammatory Odontogenic Cyst with Laser Therapy – Case Report

Purpose: Odontogenic cysts occur in the oral and maxillofacial region; most jaw 
cysts are lined by epithelium derived from odontogenic epithelium associated 
with tooth development. Odontogenic cysts can be classified as “developmental 
type” or “inflammatory type”. A correct diagnosis is essential for planning the 
treatment of conditions that compromise the maxilla-mandibular complex. Given 
that, a significative number of cystic lesions of the jaws share similar clinical and 
radiographic features, the diagnosis of odontogenic cysts, usually requires detailed 
analysis of the clinical, radiological and histopathological findings. All odontogenic 
cysts, with the exception of inflammatory periapical cyst and lateral radicular cyst, 
should be treated with surgical intervention. The periapical cystic lesions are usually 
treated by conservative endodontic treatment (periapical curettage) or surgical 
treatment (enucleation, marsupialization and decompression). In lateral radicular and 
inflammatory periapical cysts, surgery is indicated only if the lesions do not regress 
after removal of odontogenic infection intra-canal the affected tooth. In case of 
residual cyst, surgery is the only option. 
Case Report: A 55-year-old female patient, caucasian, attended the Oral-Maxillofacial 
Surgery consultation at Clitrofa - Centro Médico, Dentário e Cirúrgico, in Trofa - Portugal, 
to evaluate a dental cyst in the second quadrant diagnosed during the evaluation to 
place dental implants in the upper jaw. It was decided to carry out surgical treatment 
of the lesion using LightWalker® from Fotona with application of Er:YAG and Nd:YAG 
lasers. 
Conclusion: After a 12-month follow-up period, the patient is pain free and the lesion 
has no signs of recurrence. Laser therapy may be considered a successful treatment 
modality for inflammatory odontogenic cyst
