Oral Health-Related Quality of Life in Dutch Children Diagnosed with Oligodontia. A Cross-Sectional Study

Abstract

There is need to get insight into condition-specific oral health-related quality of life in Dutch children with oligodontia. Between October 2014 and March 2017, 11–17-year-old oligodontia patients were approached to join a study assessing the impact of oligodontia on condition-specific oral health-related quality of life (OHrQoL). The patients received a condition-specific OHrQoL questionnaire prior to the start of orthodontic treatment. Non-oligodontia children in the same age group, but also requiring orthodontic treatment, were approached to serve as a control. The Fisher’s Exact Test was used for comparison purposes with the control group because of the small group sizes. Furthermore, subgroup analyses were performed for gender, age, number of congenitally missing teeth, tooth agenesis in the aesthetic region, orthodontic classification and microdontia via independent t-tests. p-values of <0.05 were considered statistically significant. Twenty-eight oligodontia patients and 23 controls agreed to participate. The oligodontia patients’ scores were comparable to the controls except for the items about dental appearance and treatment complexity. The impact of oligodontia on OHrQoL in youngsters is limited and mainly concerns dental appearance and the complexity of the treatment.

Prevalence and patterns of tooth agenesis among patients aged 12-22 years: A retrospective study

“… 5 The prevalence of oligodontia is reported to range from 0.08% to 0.16% in various populations. 6 - 8 Previous studies on tooth agenesis have also reported that the most commonly missing teeth are the mandibular second premolars, lateral incisors, and maxillary second premolars. 2 , 4 , 5 , 9 …”

“…5 The prevalence of oligodontia is reported to range from 0.08% to 0.16% in various populations. [6][7][8] Previous studies on tooth agenesis have also reported that the most commonly missing teeth are the mandibular second premolars, lateral incisors, and maxillary second premolars. 2,4,5,9 Since the non-development of tooth germs causes many esthetic and functional problems, including the misplacement of teeth, periodontal damage, or inadequate bone height in the upper and lower jaws, the diagnosis should be established without delay in such patients, and their treatment should be planned using a multidisciplinary approach.…”
