- BACKGROUND: Infants with moderate to severe congenital heart disease (CHD) are at a higher risk for growth failure and malnutrition due to increased metabolic demands and inadequate energy intake. This state requires meals that are more frequent and a special enriched diet, which may have negative implications on oral health.AIM: To examine the oral colonisation of some bacteria associated with caries development during infancy; mutans streptococci (MS) and lactobacilli (LCB) in infants with CHD and whether their dietary intake had an impact on the bacterial levels.DESIGN: This was a prospective case-control study. 11 infants with CHD and 22 healthy, age-matched infants were enrolled. Saliva samples and food diaries were collected at 6, 9, and 12 months of age. The total viable counts of MS and LCB in saliva were determined, and energy intake, meal frequency, intake of proteins, fat, carbohydrates and sucrose were calculated.RESULTS: At 12 months of age, the MS count was higher in the CHD group than in the controls (p<0.01), and MS constituted a higher ratio of the total viable count of oral bacteria (p<0.01). Meal frequency was higher in the CHD group at 6 and 9 months of age than in the controls (p<0.05). The intake of sucrose did not differ between the groups, while the total carbohydrate intake was higher in the control group at 6 and 12 months of age (p<0.05). Compared with the control group, which had six courses of antibiotic administration, the CHD infants had 21 courses (p<0.05).CONCLUSIONS: Infants with severe CHD have higher levels of MS at 12 months of age than the healthy controls. A higher meal frequency and use of diuretic medication and antibiotics may have influenced MS colonisation.

- Objectives To identify, appraise and summarize existing knowledge and knowledge gaps in practice-relevant questions in pediatric dentistry. Methods A systematic mapping of systematic reviews was undertaken for domains considered important in daily clinical practice. The literature search covered questions in the following domains: behavior management problems/dental anxiety; caries risk assessment and caries detection including radiographic technologies; prevention and non-operative treatment of caries in primary and young permanent teeth; operative treatment of caries in primary and young permanent teeth; prevention and treatment of periodontal disease; management of tooth developmental and mineralization disturbances; prevention and treatment of oral conditions in children with chronic diseases/developmental disturbances/obesity; diagnosis, prevention and treatment of dental erosion and tooth wear; treatment of traumatic injuries in primary and young permanent teeth and cost-effectiveness of these interventions. Abstracts and full text reviews were assessed independently by two reviewers and any differences were solved by consensus. AMSTAR was used to assess the risk of bias of each included systematic review. Reviews judged as having a low or moderate risk of bias were used to formulate existing knowledge and knowledge gaps. Results Out of 81 systematic reviews meeting the inclusion criteria, 38 were judged to have a low or moderate risk of bias. Half of them concerned caries prevention. The quality of evidence was high for a caries-preventive effect of daily use of fluoride toothpaste and moderate for fissure sealing with resin-based materials. For the rest the quality of evidence for the effects of interventions was low or very low. Conclusion There is an urgent need for primary clinical research of good quality in most clinically-relevant domains in pediatric dentistry.

45,X/46,XX karyotype mitigates the aberrant craniofacial morphology in Turner syndrome
- 2013

Tidskriftsartikel (refereegranskat)abstract
- The aim of this project was to study the impact on craniofacial morphology from Turner syndrome (TS) karyotype, number of intact X chromosomal p-arms, and age as well as to compare craniofacial morphology in TS with healthy females. Lateral radiographs from 108 females with TS, ranging from 5.4 to 61.6 years, were analysed. The TS females were divided into four karyotype groups: 1. monosomy (45,X), 2. mosaic (45,X/46,XX), 3. isochromosome, and 4. other, as well as according to the number of intact X chromosomal p-arms. The karyotype was found to have an impact on craniofacial growth, where the mosaic group, with presence of 46,XX cell lines, seems to exhibit less mandibular retrognathism as well as fewer statistically significant differences compared to the reference group than the 45,X karyotype. Isochromosomes had more significant differences versus the reference group than 45,X/46,XX but fewer than 45,X. To our knowledge, this is the first time the 45,X/46,XX and isochromosome karyotypes are divided into separate groups studying craniofacial morphology. Impact from p-arm was found on both maxillary and mandibular length. Compared to healthy females, TS expressed a shorter posterior and flattened cranial base, retrognathic, short and posteriorly rotated maxilla and mandible, increased height of ramus, and relatively shorter posterior facial height. The impact of age was found mainly on mandibular morphology since mandibular retrognathism and length were more discrepant in older TS females than younger.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this project was to study the impact from Turner syndrome (TS) karyotype and age on dental arch morphology and palatal height and to compare the variables in TS with reference data from non-TS females with normal occlusion. Plaster casts from 76 females with TS (6-50 years) were analysed with respect to dentoalveolar arch dimensions and palatal height. The TS females were divided into the karyotype categories: i) 45, X ii) 45, X/46, XX iii) isochromosome, and iv) other. The 45, X/46, XX karyotype exhibited fewer statistically significant variables differing from the reference group compared with other karyotypes. TS females showed increased dentoalveolar depths, decreased maxillary but increased mandibular width, decreased posterior segments, and decreased mandibular circumference compared with the reference group. In opposition to previous reports, the palatal height did not differ compared with non-TS females. Age had an impact on nine of the variables. We conclude that the present dental arch deviations are reflecting the high frequency of malocclusions reported in TS and the subsequent need for orthodontic treatment, which might possibly be lower in the 45, X/46, XX karyotype. The palatal height did not differ from the reference group, but instead the narrow maxilla might contribute to an illusion of a higher palate. We therefore suggest using the nomination 'narrow palatal vault' instead of the commonly used term 'high palatal vault'.

Acidity and in vitro effects on dental hard tissues of pharmaceutical preparations used in paediatric cardiology
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background: The knowledge of oral health effects caused by long-term medication in medically compromised children is sparse. Besides the effects on salivary secretion, pharmacotherapy may also act directly on the dental hard tissues, with dental caries and/or erosive lesions as possible outcomes of their acid and fermentable sugar content.Methods: Thirteen pharmaceutical preparations commonly used on a long-term basis in paediatric cardiology were selected. The endogenous pH of water solutions of tablets, capsules, and liquid medicines were measured with a pH meter. The titratable acidity and the dissolution of calcium and phosphate after immersion of tooth specimens were quantified for preparations with an endogenous pH below 5.5.Results: The endogenous pH values varied between 3.03 and 9.02. Six of the 13 preparations (46%) had an endogenous pH below the critical value for enamel dissolution (pH 5.5). The captopril (12.5 mg) tablet water solution had the lowest pH while the propranolol hydrochloride mixture displayed the highest titratable acidity. The highest dissolved calcium and phosphate was displayed for captopril (12.5 mg) tablet water solution followed by acetylsalicylic acid (75 mg) tablet water solution.Conclusion: It is concluded that some pharmaceutical preparations that are commonly used on a long-term basis in paediatric cardiology may pose a hazardous threat to dental hard tissues due to their acidity.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The aim was to assess how accurately some commonly used risk factors/risk markers (predictors) for caries development could identify children with and without approximal caries as judged from bitewing radiography. Two hundred and sixtyseven consecutive 5-year-old children from two Swedish cities participated. Three experienced dentists examined the children. The predictors were the overall dmfs (de-cayed, missing and filled surfaces) value (canines and molars), the number of occlusal dmfs, the frequency of intake of between-meal sugary products, visible plaque on free smooth surfaces of second primary molars, toothbrushing habits and (before bitewing examination) an overall judgement by the examining dentist. The mean dmfs value without bitewing examination was 0.40 (SD = 1.22). Twelve percent of the children had at least one dentin lesion and 33% at least one enamel lesion that were detected from bitewing examination only. The gain from adding bitewing examination to clinical examination amounted to a mean of 1.2 approximal enamel and/or dentin lesions. The ability to correctly identify children with approximal caries from the predictors was limited; sensitivity ranged from 0.27 to 0.75 and specificity ranged from 0.41 to 0.93. The single best predictor was the dentist's overall judgement with an average precision of 73%; average sensitivity for the presence of enamel and dentin lesions was 0.48 and for the presence of dentin lesions 0.66. The rest of the predictors added little to the predictive power. It is concluded that 33% of the 5-year-olds, representing a low caries prevalence population, benefited from bitewing examination. The ability to identify these children from the predictors was, however, limited. Copyright (c) 2005 S. Karger AG, Basel.

Tidskriftsartikel (refereegranskat)abstract
- Oligodontia is defined as the congenital lack of six or more permanent teeth, excluding third molars. Oligodontia as well as hypodontia (lack of one or more permanent teeth) are highly heritable conditions associated with mutations in the AXIN2, MSX1, PAX9, EDA, and EDAR genes. Here we define the prevalence of mutations in the AXIN2, MSX1, PAX9, EDA, and EDAR genes, and the novel candidate gene EDARADD in a cohort of 93 Swedish probands with non-syndromic, isolated oligodontia. Mutation screening was performed using denaturing gradient gel electrophoresis and DNA sequence analysis. Analyses of the coding sequences of the six genes showed sequence alterations predicted to be damaging or potentially damaging in ten of 93 probands (10.8%). Mutations were identified in the EDARADD (n = 1), AXIN2 (n = 3), MSX1 (n = 2), and PAX9 (n = 4) genes, respectively. None of the 10 probands with mutations had other self-reported symptoms from ectodermal tissues. The oral parameters were similar when comparing individuals with and without mutations but a family history of oligodontia was three times more frequent for probands with mutations. EDARADD mutations have previously been reported in a few families segregating hypohidrotic ectodermal dysplasia and this is, to our knowledge, the first report of an EDARADD mutation associated with isolated oligodontia.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The general aim of this thesis was to broaden our knowledge of the signs and symptoms, genetics, and outcomes of dental implant treatment in individuals with oligodontia or ectodermal dysplasia. Article I is a population-based study in three Swedish counties of 162 individuals with oligodontia, which was a prevalence of 0.09%. The intent was to explore ways for dentists to assess symptoms from other ectodermal structures than teeth through a clinical interview and chair-side analyses. Thirty per cent had low salivary secretion rates while only 11% with no known syndrome reported symptoms from hair, nails, or sweat glands. These are, together with teeth, the ectodermal structures on which it is proposed that a clinical diagnosis of ectodermal dysplasia (ED) be based. Article II screened 93 probands with oligodontia for mutations in six genes known to cause oligodontia and hypohidrotic ED. Sequence alterations predicted to be damaging or potentially damaging were revealed in the AXIN2, MSX1, PAX9, and EDARADD genes in 14 (15%) of the probands. All mutations but one were novel. For the first time, EDARADD mutations were shown to cause isolated oligodontia. No individual who had reported ectodermal symptoms from hair, nails, or sweat glands had a mutation. Article III assessed orofacial function in individuals with different types of EDs using the Nordic Orofacial Test-Screening (NOT-S) protocol. Individuals with ED scored significantly higher in orofacial dysfunction than a healthy reference sample, especially in the Chewing and swallowing, Dryness of the mouth, and Speech domains. Article IV surveyed treatment outcome of dental implants in Swedish children up to age 16 years. In a 20-year period, only 26 patients were treated, 5 of whom had hypohidrotic ED and anodontia of the mandible. Individuals with ED had 64% failed implants compared to 6% among subjects with teeth missing due to trauma or agenesis. The main conclusions of this thesis were that (i) a check of whether one or more permanent incisors are missing will identify 65% of individuals with oligodontia and 84% of individuals missing nine teeth or more, (ii) evaluation of salivary secretion is indicated in children with oligodontia, (iii) a majority of individuals with oligodontia did not report other abnormal ectodermal organ function besides teeth, (iv) no clinical indicator discriminated between individuals with and without mutations in the tested genes, and more unidentified genes are involved in tooth morphogenesis, (v) EDARADD mutations are associated with isolated oligodontia, (vi) evaluation of orofacial function is indicated in individuals with ED, and many individuals with ED would benefit from orofacial skills training, (vii) dental implant placement is a rare treatment modality in children, (viii) individuals with hypohidrotic ED seem to present special challenges due to structural as well as direct effects of the mutations on bone, which seem to compromise osseointegration, (ix) central registers on signs and symptoms in individuals with rare disorders would help establish prevalences of various diagnoses and define treatment needs, and (x) quality registers for monitoring treatment outcomes of dental implants would promote early detection of risks and side-effects in individuals with rare disorders.
