The article is devoted to the analysis of the results of surgical treatment of ankyloglossia in children using a diode laser. The patients were divided into three age groups. The immediate and long-term results of treatment were evaluated. The postoperative period was favorable in 98,5 % of cases. After 6–9 months, very good and good treatment results were most common in the first age group (96,4 %). Improvement or normalization of sound pronunciation was noted in 86,7 % of all operated children.

A comparative analysis of the results of treatment of children with ankyloglossia was carried out. Patients are divided into three age groups (3–6 years; 7–9 years; 10–12 years) and two subgroups depending on the method (conventional surgical and diode laser method). The immediate (14 days) and long-term (9 months) results of treatment were evaluated. The study showed the advantage of using a laser in assessing immediate results and the absence of significant differences in assessing long-term results. Regardless of the method of treatment, a higher efficiency of frenuloplasty is determined at preschool age.

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%).

The article is devoted to the analysis of the indications and results of surgical treatment of ankyloglossia in children. Patients were divided into three age groups I – 3–6 years old, II – 7–9 years old, III – 10–12 years old. The result of treatment was rated as very good, good, satisfactory, unsatisfactory. It was found that the most frequent indication (86,4 %) for surgery in children was a problem of speech. A very good treatment result was most often found in the first group (76,6 %). 74,4 % of operated children who had undergone tongue training exercise and speech therapy had normalization of sound pronunciation.
