The purpose of this study was to investigate the relevant items and content of instructions for diagnosing developmental insufficiency of oral function and to clarify the trend of the problem.

The subjects of this study were 32 children (20 boys and 12 girls) diagnosed with developmental insufficiency of oral function at our clinic, which specializes in functional feeding and swallowing therapy, from April 2018 to December 2020. The study was conducted on the basis of basic patient information in the medical records. Developmental insufficiency of oral function was diagnosed using check sheets, consisting of items A, B, and C defined by the Japan Association for Dental Science. Developmental insufficiency of oral function and present complaint were checked and compared for item B.

The results showed that all children were weaning, and three had suspected developmental disabilities. Fourteen patients (44%) were referred by dental clinics. The most common complaint was too long or too short chewing time in 18 cases. Similarly, the most common tendency was checked for item B in the same category in 24 cases. In terms of the course of oral function management, 19 patients (76%) completed it within 12 months. In addition, when comparing the chief complaint with the relevant items, the dentist checked more relevant items than the chief complaint, and the agreement rate was low for nutrition (body size).

In conclusion, when a patient presents with a complaint of developmental insufficiency of oral function, it is very important for the dentist to proactively interview not only the parents but also the child;in this study, they were examined using check sheets to diagnose developmental insufficiency of oral function. Identifying the problems that are difficult for the parents and child to recognize is considered to be the most important factor for correct diagnosis.
