Burden of oral diseases predicts development of excess weight in early adolescence: a 2-year longitudinal study

Dental caries, gingivitis, and excess weight are highly prevalent, interconnected chronic conditions. The association of oral health with the development of adiposity among children is sparsely addressed. We examined the association of oral health to the development of excess weight and central obesity in early adolescence during a 2-year follow-up period. This prospective study was conducted with 2702 children aged 9-12 years at baseline from the Finnish Health in Teens study. Their weight development was followed up for 2 years. Body mass index with age- and sex-specific cut-offs and the waist-height ratio indicated weight status and central obesity. Oral health data (caries experience and gingivitis/calculus) were collected from outpatient records of public dental services. Having both caries experience and gingivitis/calculus was considered burden of oral diseases. Of the sample, 74% were caries-free but 70% exhibited gingivitis and/or calculus, and 20% had both caries experience and gingivitis/calculus. During the follow-up period, 5.3% (n = 124) and 4.7% (n = 118) of the children became overweight/obese or centrally obese, respectively. Having both caries experience and gingivitis/calculus associated with the development of excess weight in a fully adjusted model (HR 1.75, 95% CI 1.03-2.97) but not of central obesity. Caries experience or gingivitis/calculus alone did not associate with adiposity development.

CONCLUSION

Having burden of oral diseases without excess weight at early adolescence could imply future weight gain; thus, normal-weight individuals with both caries experience and gingivitis/calculus could be targeted with preventive measures. Our findings warrant further research to explore whether oral diseases and the development of obesity merely share risk factors or if their relationship is of causal nature.

WHAT IS KNOWN

• Association of excess weight with caries experience and gingivitis is known to exist both cross-sectionally and longitudinally in children and adolescents.

WHAT IS NEW

• Burden of oral diseases, that is, having both caries experience and gingivitis/calculus, was associated with becoming overweight or obese 2 years later during early adolescence. • Normal-weight individuals with burden of oral diseases at early adolescence could be targeted with preventive measures against excess weight gain.

Self-perception of periodontal health and pain experience during periodontal examination in 14- to 15-year-old Danish adolescents

OBJECTIVE

To evaluate different aspects of periodontal examination among Danish adolescents.

MATERIALS AND METHODS

In all, 521 Danish adolescents underwent a periodontal examination and answered a questionnaire concerning their self-perception of periodontal health (PH). Furthermore, 107 participants reported their pain experience during periodontal examination using a visual analog scale. The self-perception of PH and the pain experience were correlated with plaque score (PS), bleeding on probing (BOP), probing pocket depth (PPD), and interdental clinical attachment loss (CAL).

RESULTS

Good PH was reported by 424 (81%) of the participants. However, the association between PH and PS, BOP, PPD, and CAL was small (sensitivity: 7.7, 7.8, 12.0, and 0.0%, respectively). Only 57 (11%) of the participants reported bleeding gums (BG) during tooth brushing, but the correlation with BOP showed a sensitivity of 11.7%. The specificity of both self-perception of PH and BG was high. Sixty-seven (66.6%) of the participants experienced 'mild pain' during periodontal examination. There were no differences in periodontal outcomes between the pain groups (p > .05).

CONCLUSIONS

The adolescents showed a poor ability to identify themselves as having poor PH and BG, and 67 (66.6%) of the adolescents experienced mild pain during periodontal examination. The findings emphasize the need for dental staff to monitor the PH of Danish adolescents and advise them as necessary.
