Five-Year Follow-Up of a Child with Non-Syndromic Oligodontia from before the Primary Dentition Stage: A Case Report

Abstract

Background: Congenital absence of teeth is a major dental abnormality in pediatric dentistry and the absence of six or more teeth is defined as oligodontia. Few reports of patients with non-syndromic oligodontia without systemic disease have continued dental follow-up from an early age. Methods: We performed the five-year follow-up from before the eruption of the primary dentition of a Japanese child with non-syndromic oligodontia and analyzed changes in dental arch growth. Results: At the oral examination at the age of 1 year and 2 months, eight primary incisors were congenitally absent. Therefore, we made dentures for the patient at the age of 3 years and 4 months. From the age of 5 years and 1 month, the child received articulation training for dysarthria from a speech therapist to improve the function and appearance of the oral cavity. Measurement of the patient’s dental models revealed a particularly narrow dental arch, especially between the primary canines. Conclusions: Our findings highlight the importance of treatment for patients with non-syndromic oligodontia from an early age by multiple medical professionals, recognizing that the missing teeth affect the growth of the maxillofacial region.

Fusion of a Tooth with a Supernumerary Tooth: A Case Report and Literature Review of 35 Cases

“…Dental anomalies include abnormal tooth counts, morphology, size, and eruption times [1][2][3][4]. Congenital types are inherited and have a genetic basis, developmental types occur at the tooth formation stage, and acquired anomalies occur after tooth development [5].…”

Dental Abnormalities in Pediatric Patients Receiving Chemotherapy

“…We found that congenital absence after chemotherapy occurs with high frequency in premolar and 2nd molar, and microdonts occur with high frequency in premolar. Long-term follow-up is necessary because patients with dental abnormalities sometimes need prosthodontic or conservative treatment [27]. Furthermore, continuous dental support after the treatment is completed leads to better general oral health, which improves patients' quality of life [28].…”

Radiographic assessment and management of two deeply and horizontally impacted maxillary central incisors: A clinical case report

“…Maxillary central incisors have a significant impact on facial attractiveness [5] . Impaction of maxillary central incisors has the potential to cause speech problems; especially in pronouncing “S” [6] . Tipping of the adjacent teeth, space deficiency, and midline deviation were reported [7] .…”
