Gingival cyst of the adult

ABSTRACT The gingival cyst of the adult (GCA) is a rare odontogenic cyst, consisting of 0.3% of all odontogenic cysts. This case report, based on CARE guidelines for case reports, aims to present a case of a 52-year-old female patient with a symptomatic translucent nodule in the upper left anterior gingiva, measuring approximately 6mm. Excisional biopsy was performed, and the histological examination revealed multiple cystic cavities lined by the squamous epithelium of varying thickness with focal areas of nodular thickenings. The presence of clusters of cells with clear cytoplasm within epithelial thickenings was observed. PAS staining was negative in clear cells. The diagnosis of the GCA was established. Despite its rarity, GCA should be considered in the differential diagnosis of gingival lesions. Conservative surgical treatment proved to be effective, with no signs of recurrence.

Clinical features and preventive therapies of radiation-induced xerostomia in head and neck cancer patient: a literature review

Xerostomia or dry mouth is one of the most common and disturbing adverse effects following radiotherapy for head and neck cancer (HNC). This complication strongly increases the risk for dental caries, difficulties with chewing, swallowing and sleep disorders with significant impact on patients' quality of life. Current treatment approaches of xerostomia are often difficult and bring in many cases no substantial relief for the patient. This paper discusses the clinical features and current knowledge of xerostomia prevention in order to evaluate the real possibilities of reducing the incidence and severity of this complication in HNC patients. Salivary gland cytoprotectants (amifostine), muscarinic agonist stimulation (pilocarpine and bethanechol), salivary gland-sparing radiation technique (intensity-modulated radiotherapy- IMRT), surgical relocation of the submandibular gland, intraoral stent and stem cell transplantation are promising techniques that are discussed in this study (AU)
