Are Down syndrome children more vulnerable to tooth wear?

Tooth wear prevalence in individuals with Down syndrome: a systematic review

OBJECTIVES

This systematic review investigated the prevalence of tooth wear between patients with and without Down syndrome.

METHODS

Six databases (Embase, LILACS, Livivo, PubMed, Scopus and Web of Science) and grey literature (Google Scholar, OpenGrey and ProQuest) were searched until March 7, 2022. Observational studies were included to assess the differences in tooth wear prevalence and/or severity in Down syndrome and non-syndromic controls. Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) recommendations were followed. Three reviewers independently screened studies, extracted data, assessed the methodological quality (Joanna Briggs Institute) and graded the certainty of evidence through the Grading of Recommendations, Assessment, Development, Evaluation (GRADE) approach. Results were summarized through meta-analyses using a random-effects model. The protocol was registered at PROSPERO (CRD42021266997).

RESULTS

Of the 1382 records identified, six cross-sectional studies were included. Individuals with Down syndrome had a higher prevalence and were more likely to have tooth wear than individuals without Down syndrome (44% × 15%; OR = 4.43; 95% CI 3.17-6.18; p < 0.00001; I² = 8%). Also, the severity of tooth wear was higher in the Down syndrome group (n = 275) compared with the controls (n = 294). The certainty of evidence analysis was very low.

CONCLUSIONS

Based on very low certainty of the evidence, patients with Down syndrome had a higher prevalence and likelihood and severity of tooth wear when compared to those without Down syndrome.

CLINICAL RELEVANCE

Screening early tooth wear lesions should be carefully done in the Down syndrome population since its occurrence is remarkable compared to the general population.

Parents' perceptions of oral health, general health and dental health care for children with Down syndrome in Sweden

AIM

To describe parental perceptions of general health, oral health and received dental health care in Swedish children with Down syndrome (DS).

METHODS

Online questionnaire, quantitative data analysis (Chi-square test).

RESULTS

Parents of 101 children with DS (52 boys, 49 girls, mean age: 9.6 years) participated. Seventy percent rated their child's general health and 74% their child's oral health as good or very good. Parents, who rated their child's oral health as poor (8%), also reported that dental procedures were difficult. Children received dental care at general (55%) and specialist clinics (53%). Ninety-four percent of parents of children receiving specialist dental health care were satisfied compared to 70% of parents with children in general clinics. The parents most valued characteristics of dental professionals were patience (63%) and their ability to engage the child (68%). Parents wanted multidisciplinary collaboration.

CONCLUSION

Most parents rated their child's general and oral health as good or very good. Children with poor oral health were also reported to have difficulties coping with dental procedures. Parents wanted dental care to be tailored to meet their child's unique needs. They wanted dental professionals to have knowledge about children with a need for special care. Lastly, they requested multidisciplinary collaboration.

Evaluation of the craniofacial and oral characteristics of individuals with Down syndrome: A review of the literature

The aim of this investigation was to describe the craniofacial and oral characteristics of children and/or adolescents with and without Down syndrome (DS). A bibliographic search of the Medline database (via PubMed), Scopus and SCIELO was performed using the keywords "craniofacial characteristics", "dental characteristics" and "Down syndrome". Systematic reviews, observational cross-sectional and longitudinal studies were included. On the contrary, case reports, letters to the editor, editorials and opinion articles were excluded. 251 articles were recovered, and only 30 fulfilled the selection criteria. DS patients were characterized by reduced dimensions of the maxillary bone, mandible, and skull base, compared to normal patients. Likewise, some of these abnormalities influenced more frequent presentation of a class III malocclusion in these patients. On the other hand, this population group showed a higher prevalence of periodontal diseases, less risk of dental caries, and the presence of alterations in the tongue, lips, dental development and palate morphology. The quality of life of these individuals is affected by difficulties in swallowing, talking, eating or breathing through the nose. In conclusion, the craniofacial and oral characteristics of DS patients present various alterations compared to healthy patients, and these alterations have a negative impact on their quality of life.
