Background In contrast with the last century, caries epidemiology has begun integrating enamel caries into determinations of caries prevalence and experience. The objective of the present systematic review and meta-analysis was to assess the caries status including estimations of enamel caries, of European adolescents. Method Four databases (Medline Ovid, Embase, CINAHL, and SweMed+) were systematically searched from 1 January 2000 through 20 September 2021 for peer-reviewed publications on caries prevalence and caries experience in 12–19-year-olds; that also included evaluations of enamel lesions. Summary estimates were calculated using random effect model. Results Overall, 30 publications were selected for the systematic review covering 25 observational studies. Not all studies could be used in the meta-analyses. Caries prevalence was 77% (n = 22 studies). Highest prevalence was reported in the age groups 16–19 years, and in studies where caries examinations were done before 2010. The overall mean DMFS score was 5.93 (n = 14 studies) and it was significantly lower among Scandinavian adolescents than among other European adolescents (4.43 vs. 8.89). The proportion of enamel caries (n = 7 studies) was 50%, and highest in the lowest age group (12–15 years). Results from the present systematic review reflected the caries distribution to be skewed at individual-, tooth- and surface levels; at tooth and surface level, also changed according to age. Conclusions Although studies in which the caries examinations had been done in 2010 or later documented a reduction in caries prevalence, caries during adolescence still constitutes a burden. Thus, the potential for preventing development of more severe caries lesions, as seen in the substantial volume of enamel caries during early adolescence, should be fully exploited. For this to happen, enamel caries should be a part of epidemiological reporting in national registers.

International Journal of Paediatric Dentistry 2011 Background. Childhood cancer survivors may have experienced a high number of invasive medical and dental procedures, which may affect their oral health-related quality of life (OHRQoL). Aim. To compare children who have survived cancer and children without cancer with respect to OHRQoL. Design. In a cross-sectional study, we compared the OHRQoL of children treated for cancer at Aalborg Hospital with the OHRQoL of classmates without cancer. All children answered The Danish version of the Child Perceptions Questionnaire (CPQ). Children aged 8-10 (n = 95) answered CPQ(8-10) , with 27 questions, and children aged 11-14 (n = 138) answered the CPQ(11-14,) with 39 questions. Results. Children with cancer rated their OHRQoL better or equal to those without cancer. The mean overall CPQ(8-10) score was 5.6 (95% CI: 2.5-8.6) among 18 children who have survived cancer and 8.8 (95% CI: 7.3-10.3) among those without cancer (n = 77); the mean difference was -3.3 (95% CI: -6.5 to 0.1). The overall mean CPQ(11-14) score was 12.5 (95% CI: 6.8-18.2) among 24 children who have survived cancer and 11.8 (95% CI: 10.3-13.3) among those without cancer (n = 114); the mean difference was -0.7 (95% CI: -4.9 to 6.3). Conclusion. Cancer and cancer treatment during childhood was not associated with a decreased OHRQoL.

Udgivelsesdato: 2008-Jun BACKGROUND: The few published studies on caries among childhood cancer survivors are small and their results are conflicting. The study aim was to examine the risk of dental caries among children who have survived cancer. PROCEDURE: We included 299,426 7-year-old, 313,461 12-year-old, and 301,930 15-year-old children born between 1984 and 1988 in a nationwide population-based study linking records from Danish Cancer Registry with records from the national database on oral health. Children whose dental examinations had been preceded by a cancer diagnosis (288 7-year-old, 459 12-year-old, and 526 15-year-old) were compared with children without cancer according to presence of caries: caries-free children; children with any caries experience; and children with severe caries experience (i.e., caries in one or more smooth tooth surface). RESULTS: Children diagnosed with cancer before the age of 5 years did not have increased caries prevalence in permanent teeth at ages 12; and 15. Children diagnosed with cancer between 5 and 6 years of age had an increased prevalence of severe caries at age 12 years (prevalence ratio (PR) = 1.59 (95% CI: 1.09-2.31; P = 0.02)), but this difference disappeared by age 15. For children diagnosed with cancer at 5 or 6 years of age and who received radiation therapy the PR of severe caries was 1.52 (95% CI: 0.97-2.37; P = 0.07), 2.13 (95% CI: 0.89-5.10; P = 0.09), and 0.31 (95% CI: 0.07-1.45; P = 0.13) at ages seven, 12 and 15 years respectively. CONCLUSION: Cancer and cancer treatment during childhood are risk factors for caries.

Introduction: The aim of the present study is to clinically analyse the influence of pre- treatment of enamel with ozone prior to fissure sealing with flowable composite material, on retention of the seal. Retention of the nanohybrid flowable composite material as a material for fissure sealing was also analysed through the clinical period of 24 months. Materials and methods: GroupAconsisted of 79 healthy permanent molars who were treated with ozone from KaVo Healozone device before the application of Voco Grandio Flow flowable composite. Group B consisted of 75 healthy permanent molars who were also sealed with Voco Grandio Flow but without the pre-treatment with ozone. Testing of the material’ s retention was conducted after 24 months of clinical use. Following values were assessed: 0- complete retention, 1-loss of 1/3, 2-loss of 2/3, 3- complete loss of seal, 4-caries. Chi square test was used for statistical analysis.Results: After 24 months of clinical use, complete retention was found on 82.3% of the teeth in group A, and 84% in group B. Caries was found in 1.3% of the cases in group B only. No statistically significant differences between the groups (v2 = 1.976 ; P = 0.577) were found. Conclusion: Considering the fact that ozone had no negative effect on retention of the sealing material after 24 months, we concluded that it can be used as pre-treatment of enamel before fissure sealing. Sealing the fissures with nanohybrid flowable composite showed a high degree of retention and consequently excellent prevention of occlusal caries.
