Surgical treatment of jaw inflammatory odontogenic cysts in primary teeth: a retrospective analysis

Abstract

Relevance. Odontogenic cysts in children are the most common bone pathology. The study aimed to conduct a retrospective descriptive analysis of inflammatory odontogenic cysts cases associated with primary teeth in children.Material and methods. The study analysed the medical records of children diagnosed with "radicular cyst associated with a primary tooth" from 2015-2020. We studied the following characteristics, namely, sex, age, location of the process, condition of the teeth in question, surgical treatment techniques and outcome. The data obtained were processed by methods of variational statistics. The Student t-test assessed the significance of differences.Results. The study analysed 60 cases of inflammatory odontogenic cysts in children aged 6 to 13 years. Cysts were more often associated with the primary lower second molars previously treated with the resorcinol-formaldehyde resin therapy. The period from the tooth treatment to the cyst diagnosis was 3 to 5 years. The treatment of cysts applied methods of a gentle and traditional cystotomy. Fifty-one children (85.0%) had follow-up examinations. All children showed bone tissue restoration during the period of 4 to 12 months and spontaneous eruption of permanent teeth in 3-8 months. Only 4 cases (7.8%) required orthodontic correction of permanent teeth position.Conclusion. Primary lower molars, previously treated with resorcinol-formaldehyde resin, are the most common cause of jaw inflammatory odontogenic cysts in children. Low-traumatic surgical methods preserving the follicles of permanent teeth are highly effective (88.2%).
