Dentigerous cyst is the most common odontogenic development cyst. If the cyst reaches a large size (>2 cm in diameter), swelling, mild sensitivity, tooth mobility, and displacement may be observed. The classic treatment for dentigerous cysts is enucleation and extraction of the involved tooth. This case report presents follicular cyst of unerupted permanent tooth. Case Report: 11-year-old girl, radiographic examination showed a radiolucent area from the mandibular right first premolar to mandibular deciduous second molar. Intraorally there was expansion of the buccal cortex to 85, 44th tooth. The mucosa over the expansion was normal. On palpation was no tender. Due to the age of the patient and cyst size, enucleation of the lesion is decided. Under local anesthesia following strict aseptic conditions, a full thickness mucoperiosteal flap was raised, an ostectomy on the crestal bone was performed. The cyst was enucleated along with extraction of mandibular deciduous second molar. The flaps were placed in its original position and sutured. Cyst was sent for histopathological examination. The follow-up was performed periodically under radiographic examinations during 8 months and it was observed successful regeneration of bone.

BACKGROUND. In the worldwide every 40 seconds one person takes their life, annually 1 million people die on Earth by the means of suicide. Regardless of gender it is one of the main 3 causes of death in the population aged between 15-29. There have a tendency to increase of suicide rates with each passing year in the Mongolia. Therefore, our study goal is to determine the utilized methods and to identify some of the factors influencing the escalation of this phenomenon. The data and materials were gathered by quantitative research method from the post-mortem examination reports provided from the central archive of National Institute of Forensic Science according to the descriptive research design. The fact that the bulk of the increasing suicide cases might be attributed to the unemployed and working-age men without any chronic illnesses suggests correlation with gender and socio-economic status.
