Introduction: The development of the dentomaxillary system in children involves a normal thyroid function. Juvenile hypothyroidism has different complications depending on the congenital or acquired nature of it.

Objective: To identify periodontal changes under the conditions of chronic autoimmune thyroiditis and subclinical hypothyroidism.

Material and method: The study group comprised 24 young patients, 15 girls and 9 boys (15.2±2.8 years) with chronic autoimmune thyroiditis and subclinical hypothyroidism; the control group included 36 young patients (21 girls and 15 boys - [16±2.1 years]) without thyroid pathology.

Results: Facial changes: microretrognathia – 12 cases (52%), pale and infiltrated lingual and jugal mucosa; 14 children (60.8%) – lingual mycotic detritus; 8 children (34.7%) - ‘geographic’ tongue. Occlusive disorders: frontal malocclusion in the sagittal plane – 19 children (80%); frontal reversed occlusion – 8 cases (34.7%), open occlusion – four cases (17.4%), lower proalveolodentition with interdental spacing – 17 children (68%).

Dental malposition: Reversed overlap – 11 cases (47.8%), eruption of central upper incisors in vestibular position – 1 case (4.3%); bilateral ectopic canine – 1 case (4.3%); dentoalveolar incongruence – 1 case (4.3%). Dental eruption chronology: delayed eruption – 19 patients (78.2%), prolonged mixed dentition – 14 patients (60.8%); taurodontia – upper molars – 1 case (4.3%). Periodontal changes: pathological tooth mobility, pathological diastemas, gingival retreats, true periodontal pockets – 8 cases (34.7%). Compared to the control group: occlusive disorders – 3.4%, dental malformations – 7.8%, periodontal changes – 1.8%.

Conclusions: Subclinical hypothyroidism in chronic autoimmune thyroiditis induces and intensifies dento-maxillary and periodontal changes at puberty.

Keywords: subclinical hypothyroidism, chronic autoimmune thyroiditis, periodontitis, puberty.
