To determine the association between maternal age at delivery and caries in offspring. This registry-based cohort study included all children born between 2000 and 2003 and who were residing in Stockholm County, Sweden, at 7 years of age. Between 2007 and 2010, the cohort (n = 65,259) was examined to determine caries experience (deft scores) at 7 years of age. Age of mother at childbirth was retrieved from the patient histories. Data were analysed using linear regressions. The lowest mean deft occurred in children born to mothers aged 25–34 years. The final model – adjusted for sex, income, educational level, migration background, family situation, smoking, obesity, small for gestational age, and number of siblings – found that young mothers and older mothers were significant risk indicators for caries experience at 7 years of age. The present study found a U-shaped relationship between maternal age at childbirth and caries experience in the offspring at age 7 years. The offspring of mothers under 25 or over 34 years of age are at greater risk of having more teeth with caries experience. [ABSTRACT FROM AUTHOR]

Objective: To economically evaluate a caries-preventive program "Stop Caries Stockholm" (SCS) where a standard program is supplemented with biannual applications of fluoride varnish in toddlers and compared it with the standard preventive program.Material and Methods: Data from the cluster randomized controlled field trial SCS including 3403 children, conducted in multicultural areas with low socioeconomic status was used. The difference in mean caries increment between the examinations; when the toddlers were 1 and 3 years old, was outcome measure of the intervention. The program was evaluated from a societal as well as a dental health care perspective. The incremental cost-effectiveness ratio (ICER) was calculated as the incremental cost for each defs prevented.Results: Average dental health care costs per child at age 3 years were EUR 95.77 for the supplemental intervention and EUR 70.52 for the standard intervention. The ICER was EUR 280.56 from a dental health care perspective and EUR 468.67 and considered high.Conclusions: The supplemental caries intervention program was not found to be cost-effective. The program raised costs without significantly reducing caries development. A better alternative use of the resources is recommended.Trial Registration: www.controlled-trials.com (ISRCTN35086887).

The aim of this study was to investigate the relationship between body mass index (BMI kg/m2), the inflammatory mediator tumor necrosis factor alpha (TNFalpha), and interleukin-8 (-8) in gingival crevicular fluid (GCF) from 32 obese subjects aged between 13 and 24 years. Gingival inflammation (GBI %), pathological pocket depths, and alveolar bone loss diagnosed on radiographs were recorded. The GCF was collected from six sites per subject using periopaper, and the volume was determined using Peritron 8000. The levels of TNFalpha and IL-8 were determined using ELISA kits. Within the whole group, there was no significant relationship between BMI and the variables age, GBI %, number of periodontal pockets, smoking, and the levels of TNFalpha or IL-8. In subjects with BMI > or =40, however, there was a statistically significant correlation (r= 0.74, P< 0.01) between the level of TNFalpha in GCF and BMI. The correlation coefficient between BMI and TNFalpha in subjects with BMI > or =40 differed significantly (P< 0.05) compared to that between subjects with BMI <40. The level of TNFalpha in GCF was positively correlated (P< 0.05) with BMI in subjects with no periodontal pathological pocket. No significant correlation was found between the level of IL-8 and BMI. The results indicate that BMI positively correlates with TNFalpha in GCF in the group of young subjects with BMI > or =40 as well as in the subjects with no pathological periodontal pocket (> or =4 mm) and that TNFalpha in GCF may be affected by the obese condition through a systemic effect.

The orofacial function in 20 children with Down syndrome was evaluated after 4 years of palatal plate therapy in 9 of the children (PPG); the remaining 11 were untreated age-matched controls (CG). All 20 children had received continuous orofacial physical therapy from their speech therapist during the treatment period. A clinical extra- and intraoral examination was performed, including oral motor function, facial expression, the occurrence of malocclusions, and hypertrophic tonsils. A questionnaire requesting data on breathing patterns, drooling, eating problems, and communicative preferences was answered by the parents. An articulation assessment was performed by two speech and language pathologists blinded to the treatment status of the children in order to find out whether the palatal plate had stimulated to improved oral speech behavior. The results for oral motor function showed significant differences between the groups in favor of the PPG for the summary variables for: visible tongue (P < 0.01), visible tongue during non-speech periods (P < 0.05), and lip-rounding during spontaneous speech (P < 0.01). During non-speech time, the PPG had their mouths open significantly less than the CG (P < 0.05). Expressivity of facial expression on a visual analog scale in the PPG scored 75.6 +/- 13.3 compared to 51.8 +/- 25.7 in the CG (P < 0.05). The intraoral examination showed that 6/9 children in the PPG and 7/11 in the CG had enlarged tonsils, resulting in more than 50% inter-tonsillary space reduction. Despite these findings, and no significant differences between the groups with respect to mouth/ nose breathing, nocturnal snoring was significantly less in the PPG than in the CG (P < 0.05), according to the parental questionnaire. After 4 years of palatal plate therapy, orofacial function had improved significantly in the 9 PPG children and specifically in terms of tongue position and lip activity. [ABSTRACT FROM AUTHOR]

Overweight and obesity are growing problems in the world today. A recent survey shows that about 30% of the adolescent and adult Swedish population is overweight or obese. The etiology is a combination of many factors, the most important of which are physical inactivity and high caloric diet. Obese children have a normal to accelerated growth rate despite low growth hormone (GH) levels. The aim of our study was to investigate whether craniofacial morphology differs between obese adolescents and normal weight adolescents. Lateral cephalograms from 39 adolescents with obesity, aged 14–16 years, were analysed and compared with lateral cephalograms from an equal number of sex- and aged-matched controls. Compared to the controls, the subjects in the obesity group showed increased mandibular length, prognathic jaws and a reduced upper anterior face height. Despite low GH levels, obese children have normal levels of insulin-like growth factor (IGF-1). Since we found an advanced craniofacial growth in obese adolescents with low GH and high IGF-1 serum levels, craniofacial growth may be more dependent on free circulating IGF-1 than on the locally produced portion.

Oral motor function was evaluated after 4 years of palatal plate therapy in nine children with Down syndrome (DS); 11 children with DS constituted the control group. During the treatment period all children had orofacial physiotherapy with their speech pathologist. An extraoral examination was performed, as was a video registration of the face. Nine different variables showing positions of the lips, tongue, and facial expression were examined. Children in the palatal plate group (n = 9) had significantly more rounding lips during speech (P< 0.05) than children in the control group (n = 11). The active variables describing normal muscle tension were diagnosed to constitute 81.0% +/- 11.0% of the registered video time in the palatal plate group, compared with 68.2% +/- 22.5% in the control group. Statistically significant differences were found between the groups in the summary variables describing an inactive open mouth and inactive tongue protrusion (P< 0.01). The results indicate that palatal plate therapy has a long-term effect on oral motor function. [ABSTRACT FROM AUTHOR]

With the improving cure rate in childhood malignancies, increasing interest has been focused on the long-term survivors of childhood cancer and the quality of their life. The severity of long-term disturbances in dental and craniofacial development is dependent on the age of the child at diagnosis, if chemotherapy is combined with radiation or not. With regard to craniofacial development combination chemotherapy has no effects compared with healthy controls, whereas children treated cranial irradiation before 5 years of age exhibit a reduced growth of the mandible. Conditioning before bone marrow transplantation with total body irradiation results in a significantly reduced growth of the craniofacial skeleton. The mandible was four times more radiosensitive compared with the maxilla. With attention to the dental and craniofacial development, occlusion and craniomandibular function, children in risk groups should be followed, and given prophylactic treatment and intervention at appropriate times to reduce the consequences of the disease itself and the therapy given.

The aim of this investigation was to present the 2-year follow-up results of a longitudinal study examining the influence of growth hormone (GH) substitution on dental maturity in healthy children of short stature (height <2 SD). At baseline, the children were divided into a GH-deficient group and a GH non-deficient group, and comparisons were made with healthy controls (height between -2 SD and 2 SD) and between the short stature groups. The GH-substituted group included 24 children (8 F, 16 M) with a mean chronological age of 12.20 ± 2.40 years, whereas the GH non-substituted group included 19 children (5 F, 14 M) with a mean chronological age of 11.00 ± 2.40 years. The corresponding age- and sex-matched control groups constituted 48 and 36 children, respectively. The mean dental age in the GH-substituted group was 11.60 ± 2.70 years, compared to their healthy controls 12.40 ± 2.60 years (P < 0.05). The dental age for the GH non-substituted children was 10.20 ± 2.60 years compared to their controls 11.90 ± 2.60 years (P < 0.001). GH-substituted children show an acceleration in their dental maturity in contrast to controls, whereas in non-substituted children the acceleration is less pronounced. [ABSTRACT FROM AUTHOR]
