tubes were found simultaneously in the dental cervix of the lower primary central incisors.

A 4-year-old boy was referred with the chief complaint of swelling around his lower
primary incisors. Clinical examinations revealed inflamed gingival tissue around the lower
primary central incisors and severe mobility of these teeth. Small transparent plastic tubes
were found in the dental cervix of the lower primary central incisors, which were likely
accidentally inserted during play. A periapical radiograph revealed diffuse alveolar bone loss
between the lower primary central incisors. Irrigation of the affected teeth was performed.
Table 3 summarizes the transitional changes in his periodontalhealth. Three months after the
first visit, an examination revealed recovery of gingival attachment, and a periapical
radiograph showed that the alveolar bone defects between the lower central incisors were
being repaired. However, the periodontal condition of the affected teeth could not be restored
to their original status. It was concluded that the type of periodontitis caused by such an
incident is not progressive, unlike other periodontal diseases such as prepubertal and juvenile
periodontitis.
