Abstract
PURPOSE Critically review and summarise existing knowledge on prevalence of oral, dental, and craniofacial side-effects of antineoplastic treatment in childhood cancer survivors (CCS). METHODS A literature search was conducted for studies reporting on children aged 4-19 years treated for any type of malignancy up to the age of 15 years and for whom, at the time of the examination, more than 8 months have elapsed since the end of treatment. Data regarding dental late effects on teeth and craniofacial complex were collected and mean prevalence of each defect was reported. RESULTS From the 800 articles identified, 17 studies fulfilled inclusion criteria and were included. A total of 983 CCS were examined, with the total number of healthy controls being 1266 children. Haematological malignancy was the most prevalent diagnosis with the age at diagnosis ranging between 0-15 years. Multiple antineoplastic protocols were implemented with the elapsed time being 8 months up to 17 years. One-third of CCS experienced at least one late effect, with corresponding value for the control group being below 25%. Among the defects identified clinically, microdontia, hypodontia and enamel developmental defects were recorded in 1/4 of CCS. Impaired root growth and agenesis were the two defects mostly recorded radiographically. The effect on dental maturity and on salivary glands was unclear. CONCLUSION CCS are at risk of developing dental late effects because of their disease and its treatment and therefore, routine periodic examinations are essential to record their development and provide comprehensive oral healthcare.

Abstract
Purpose To explore caries predictors at age 1 year and caries development at ages 5 and 7 years in two groups of children following different fluoride-based preventive programs. Methods We conducted a prospective cluster-randomized controlled intervention trial with two parallel arms comparing two prevention programs: one program included fluoride varnish applications every 6 months, the other did not; otherwise, the programs were the same. Participants were 1- and 3-year-old children enrolled at 23 dental clinics in high-risk areas in Stockholm, Sweden. The baseline examination included structured interviews. Caries data were extracted from dental records. The primary outcome measures were ICDAS 1–6 > 0 at baseline (age 1 year) and defs > 0 at ages 2, 3, 5, and 7 years. The secondary outcome measure at age 7 was DFS > 0. Results Continuous caries development occurred: defs > 0 in 23% at 5 years and in 42% at 7 years. We found no difference in caries development between children who had or had not received fluoride varnish as toddlers. At age 1-year, significant predictors for dental caries in later preschool years were immigrant background, family income, and sweets consumption. Fluoride toothpaste > once a day at 1 year had an OR < 1 for defs > 0 at 5- and 7 years. Conclusions For toddlers, fluoride varnish does not seem to be an adequate prevention tool. Brushing with fluoride toothpaste from 1 year of age could not arrest caries development. Immigrant background was the strongest predictor. A new toolbox as well as collaborative upstream actions for reducing free-sugar intake are needed.

Abstract
BACKGROUND Birth order has been shown to affect the health of the child; less is known, however, about how birth order affects caries development in children. Thus, the present study investigated the association between birth order and dental caries development in young children. METHODS This retrospective registry-based cohort study included all children born in 2000-2003 who were residing in Stockholm County, Sweden, at age 3 years (n = 83,147). The study followed the cohort until subjects reached 7 years of age. Children with registry data on dental examinations and sociodemographic characteristics at ages 3- and 7 years constituted the final study cohort (n = 65,259). The outcome variable was "caries increment from age 3- to 7 years" (Δdeft > 0) and the key exposure, "birth order", was divided into five groups. A forward stepwise logistic binary regression was done for the multivariate analysis with adjustments for sociodemographic factors. RESULTS At age 3 years, 94% had no fillings or manifest caries lesions. During the study period, 22.5% (n = 14,711) developed dental caries. The final logistic regression analysis found a statistically significant positive association between birth order and caries increment. Further, excess risk increased with higher birth order; with the mother's first-born child as reference, risk for the second-born child was OR 1.17, 95% CI = 1.12-1.23; for the third-born child, OR 1.47, 95% CI = 1.38-1.56; for the fourth-born child, OR 1.69, 95% CI = 1.52-1.88; and for the fifth-born or higher birth-order child, OR 1.84, 95% CI = 1.58-2.14. CONCLUSIONS These findings show that birth order influences caries development in siblings, suggesting that birth order can be regarded as a predictor for caries development in young children. This factor may be helpful in assessing caries risk in preschool children and should be considered in caries prevention work in young children with older siblings.

Abstract
Background Dentinogenesis imperfecta (DGI) is a heritable disorder of dentin. Genetic analyses have found two subgroups in this disorder: DGI type I, a syndromic form associated with osteogenesis imperfecta (OI), and DGI type II, a non-syndromic form. The differential diagnosis between types I and II is often challenging. Thus, the present cross-sectional study had two aims: to (i) investigate the prevalence and incidence of DGI type II among Swedish children and adolescents and (ii) search out undiagnosed cases of DGI type I by documenting the prevalence of clinical symptoms of OI in these individuals. We invited all public and private specialist pediatric dental clinics (n = 47) in 21 counties of Sweden to participate in the study. We then continuously followed up all reported cases during 2014−2017 in order to identify all children and adolescents presenting with DGI type II. Using a structured questionnaire and an examination protocol, pediatric dentists interviewed and examined patients regarding medical aspects such as bruising, prolonged bleeding, spraining, fractures, hearing impairment, and family history of osteoporosis and OI. Joint hypermobility and sclerae were assessed. The clinical oral examination, which included a radiographic examination when indicated, emphasized dental variables associated with OI. Results The prevalence of DGI type II was estimated to be 0.0022% (95% CI, 0.0016–0.0029%) or 1 in 45,455 individuals. Dental agenesis occurred in 9% of our group. Other findings included tooth retention (17%), pulpal obliteration (100%), and generalized joint hypermobility (30%). Clinical and radiographic findings raised a suspicion of undiagnosed OI in one individual, a 2-year-old boy; he was later diagnosed with OI type IV. Conclusions These results show a significantly lower prevalence of DGI type II than previously reported and point to the importance of excluding OI in children with DGI.

Abstract
Introduction Maternal health during pregnancy plays a part in child health, and several conditions have been associated with adverse child outcomes. Objectives To determine the socioeconomic determinants and maternal health factors associated with dental caries in young children. Methods This cross-sectional study is part of a register-based cohort study including all children who were born from 2000 to 2003 and were residing in Stockholm County, Sweden, at age 3 y (n = 73,658). The study followed the cohort until individuals were 7 y old. The final study cohort comprised all children examined at 3 and 7 y (n = 65,259). Data on socioeconomic conditions, maternal health, and maternal health behavior were extracted from Swedish national registries. The multivariate analyses used 2 outcomes: caries experience at age 3 and 7 y (deft > 0 [decayed, extracted, and filled teeth]). Results The results of this study show that socioeconomic and maternal health behaviors during pregnancy are important determinants of oral health in their preschool offspring. When all significant risk factors were present, the cumulative probability of being diagnosed with dental caries at age 7 y was 75%. Conclusion This study also showed that maternal obesity and smoking during pregnancy were predictors of dental caries in preschool children. Strategies must be developed for increasing maternal motivation and self-efficacy and providing mothers with knowledge and caries-preventive tools. Knowledge Transfer Statement The results of this study inform clinicians about the importance of including a more detailed history regarding maternal health and maternal health behaviors during pregnancy to assess caries risk in preschool children. Education, income, and other socioeconomic factors are difficult to modify in the short term. Therefore, strategies must be developed to increase parental motivation and self-efficacy to give parents the determination, knowledge, and tools for prevention.

Abstract
Child abuse and neglect (CAN) are likely to have negative consequences on health; however, for oral health, studies on associated outcomes are sparse. The purpose of this study was to assess oral health and oral health behaviors in relation to suspected CAN among children being investigated by the Swedish Social Services. The material comprised data from the Social Services and dental records; the sample, 86 children and 172 matched controls. The children in the study group had a higher prevalence of dental caries than the control group; in addition, levels of non-attendance and dental avoidance were high, as was parental failure to promote good oral health. We found four factors that, taken together, indicated a high probability of being investigated because of suspected CAN: prevalence of dental caries in primary teeth, fillings in permanent teeth, dental health service avoidance, and referral to specialist pediatric dentistry clinics. If all four factors were present, the cumulative probability of being investigated was 0.918. In conclusion, there is a high prevalence of dental caries, irregular attendance, and a need for referral a pediatric dental clinic among Swedish children under investigation due to suspected CAN. Social context is an important factor in assessing the risk of developing dental caries, the inclination to follow treatment plans, and the prerequisites for cooperation during treatment. Routinely requesting dental records during an investigation would provide important information for social workers on parental skills and abilities to fulfill the basic needs of children.

Abstract
Caesarean section has been shown to affect the health of the child. Only a few studies have investigated whether the mode of delivery is associated with dental caries, and they present conflicting results. Our study investigated whether dental caries was associated with delivery method in Swedish preschool children. This retrospective register-based cohort study included all children born from 2000 to 2003 who were residing in Stockholm County, Sweden, at 3 y of age (n = 83,147). The study followed the cohort until individuals were 7 y of age. Children examined at 3 and 7 y constituted the final study cohort (n = 65,259). We dichotomized the key exposure “delivery starts by caesarean section” and analyzed it in univariate analyses as well as in multivariate analyses. The multivariate analyses used 3 outcomes: caries experience at age 3 (deft >0 [decayed, extracted, and filled teeth]), caries increment between 3 and 7 y of age (Δdeft > 0), and caries experience at age 7 (deft > 0). Of the final cohort, 15% (n = 9,587) were delivered by caesarean section. At 3 y of age, the results showed no statistically significant association between caesarean section and caries experience (odds ratio = 0.92, 95% confidence interval [CI] = 0.82 to 1.04). Between 3 and 7 y of age, the association of caesarean section on caries increment was 0.88 (95% CI = 0.83 to 0.94) and at 7 y of age, 0.88 (caries experience; 95% CI = 0.82 to 0.94). Higher mean values for caries experience and caries increment were observed in vaginally delivered children. We found that preschool children who were delivered by caesarean section do not represent a group with an excess risk of developing dental caries. Furthermore, the statistically significant associations with caries increment and caries experience at age 7 were negative. Knowledge Transfer Statement: Children born by caesarean section are at greater risk of developing asthma and obesity. The proportion of elective caesarean sections without a medical indication has increased over the years; therefore, it is important to know how this mode of delivery affects oral health of the child. The results show that children who are delivered by caesarean section are not at greater risk of developing dental caries, and clinicians can use these findings in their risk assessment.

Abstract
Dental anxiety affects approximately 9% of children and is associated with poor oral health, pain, and psychosocial problems. The objective of this study was to investigate the efficacy of cognitive behavioral therapy (CBT) for children with dental anxiety in specialist pediatric dentistry. The study used a parallel-group superiority randomized controlled trial design. The primary outcome measure was the behavioral avoidance test; assessors were blind to treatment allocation. Participants were 8 boys and 22 girls 7 to 18 y old (mean ± SD, 10 ± 3.1). Children fulfilling the diagnostic criteria for dental anxiety were randomized to CBT (n = 13) or treatment as usual (n = 17), such as various sedation methods. Psychologists provided 10 h of CBT based on a treatment manual. Treatments were conducted in a naturalistic real-world clinical setting. Assessments were conducted before the treatment, 3 mo after the start of treatment, and at 1-y follow-up. The analyses of the primary outcome measure by repeated-measures analysis of variance and independent t test showed that children receiving CBT made superior, statistically significant improvements at follow-up (16.8 ± 2.4) compared with treatment as usual (11.4 ± 3.1, P < 0.01). A large between-group effect size (Cohen’s d = 1.9) was found. Following treatment, 73% of those in the CBT group managed all stages of the dental procedures included in the behavioral avoidance test compared with 13% in the treatment-as-usual group. Furthermore, 91% in the CBT group compared with 25% in the treatment-as-usual group no longer met the diagnostic criteria for dental anxiety at the 1-y follow-up according to the secondary outcome measure. Measures of dental anxiety and self-efficacy showed larger improvements in the CBT group compared with controls. We conclude that CBT is an efficacious treatment for children and adolescents with dental anxiety and should be made accessible in pediatric dentistry (ClinicalTrials.gov: NCT01798355). Knowledge transfer statement: The results of this study can be used by decision makers and clinicians when planning to implement evidence-based treatment in pediatric dentistry and give children and adolescents access to methods for treating dental anxiety. The results can also be used by parents of children with dental anxiety when asking dentists to cooperate with psychologists using cognitive behavioral therapy.

Abstract
Amelogenesis imperfecta (AI) is a rare, genetically determined defect in enamel mineralization. Existing treatment recommendations suggest resin-composite restorations until adulthood, although such restorations have a limited longevity. New crown materials allow for minimal preparation techniques. The aim of this study was to compare the quality and longevity of 2 crown types—Procera and IPS e.max Press—in adolescents and young adults with AI. A secondary aim was to document adverse events. We included 27 patients (11 to 22 y of age) with AI in need of crown therapy in a randomized controlled trial using a split-mouth technique. After placing 119 Procera crowns and 108 IPS e.max Press crowns following randomization, we recorded longevity, quality, adverse events, and tooth sensitivity. After 2 y, 97% of the crowns in both crown groups had excellent or acceptable quality. We found no significant differences in quality between Procera and IPS e.max Press crowns. Tooth sensitivity was significantly reduced after crown therapy ( P < 0.001). Endodontic complications occurred in 3% of crowns. The results show that it is possible to perform crown therapy with excellent results and without severe complications in young patients with AI. The study is registered at http://www.controlled-trials.com (ISRCTN70438627).

METHODS Dental records of all children in the age 0-6 years who underwent GA at a specialist paediatric dentistry clinic during 2006-2011 were studied with regard to decayed-missed-filled teeth, traumatic injuries, emergency visits, behaviour management problems and the history of attendance. The final sample consisted of 134 children. Matched controls were selected among recall patients who had not received treatment under GA. STATISTICS Fishers exact test or Pearson Chi-square test analysed response distribution and comparisons between groups, and for multivariate analyses, logistic regression was used. RESULTS The results show that children treated under GA had significantly higher caries prevalence, apical periodontitis and infections due to pulpal necrosis. Dental neglect as well as dental disability was significantly more prevalent in the GA group compared to the control group. In a multivariate analysis with dental neglect as independent factor, dental disability was the only significant factor (p = 0.006). CONCLUSIONS Children treated under general anaesthesia were significantly more often diagnosed with both dental neglect and dental disability. Dental disability was the only factor significantly related to dental neglect. There is a need for improved documentation in the dental records to better identify dental neglect and dental disability, and also a continued training of dentists regarding child protection.

Abstract
BACKGROUND To our knowledge, no randomized toxicity studies have been conducted to compare myeloablative conditioning (MAC) and reduced-intensity conditioning (RIC) in allogeneic haematopoietic stem cell transplantation (HSCT). METHODS Adult patients ≤60 years of age with myeloid leukaemia were randomly assigned (1 : 1) to treatment with RIC (n = 18) or MAC (n = 19) in this Phase II single-centre toxicity study. RESULTS There was a maximum median mucositis grade of 1 in the RIC group compared with 4 in the MAC group (P < 0.001). Haemorrhagic cystitis occurred in eight of the patients in the MAC group and none in the RIC group (P < 0.01). Results of renal and hepatic tests did not differ significantly between the two groups. RIC-treated patients had faster platelet engraftment (P < 0.01) and required fewer erythrocyte and platelet transfusions (P < 0.001) and less total parenteral nutrition (TPN) than those treated with MAC (P < 0.01). Cytomegalovirus (CMV) infection was more common in the MAC group (14/19) than in the RIC group (6/18) (P = 0.02). Donor chimerism was similar in the two groups with regard to CD19 and CD33, but was delayed for CD3 in the RIC group. Five-year transplant-related mortality (TRM) was approximately 11% in both groups, and rates of relapse and survival were not significantly different. Patients in the MAC group with intermediate cytogenetic acute myeloid leukaemia had a 3-year survival of 73%, compared with 90% among those in the RIC group. CONCLUSION Reduced-intensity conditioning had several advantages compared with MAC, including less mucositis, less haemorrhagic cystitis, faster platelet engraftment, the need for fewer transfusions and less TPN, and fewer CMV infections. Both regimens were tolerated and TRM was low.

Abstract
OBJECTIVES To investigate the correlation between age, degree of disturbances in dental development, and vertical growth of the face in children treated with hematopoietic stem cell transplantation (HSCT). PATIENTS 39 long-term survivors of HSCT performed in childhood and transplanted before the age of 12, at a mean age of 6.8±3.3 years. METHODS Panoramic and cephalometric radiographs were taken at a mean age of 16.2 years. For each patient two age- and sex-matched healthy controls were included. The area of three mandibular teeth was measured and a cephalometric analysis was performed. RESULTS The mean area of the mandibular central incisor, first and second molar was significantly smaller in the HSCT group, and the vertical growth of the face was significantly reduced, especially in the lower third, compared to healthy controls. A statistically significant correlation between age at HSCT, degree of disturbances in dental development, and vertical growth of the face was found. Children subjected to pre-HSCT chemotherapy protocols had significantly more growth reduction in vertical craniofacial variables compared to children without pre-HSCT chemotherapy. Conditioning regimens including busulfan or total body irradiation had similar deleterious effects on tooth area reduction and craniofacial parameters. CONCLUSIONS The younger the child is at HSCT, the greater the impairment in dental and vertical facial development. This supports the suggestion that the reduction in lower facial height found in SCT children mainly is a result of impaired dental development and that young age is a risk factor for more severe disturbances.

Abstract
The purpose of this study was to identify and compare the perspectives of dental students towards their career choice and dental education in Japan and Sweden. One hundred and fourteen dental students from the Nippon Dental University, Japan and 43 dental students from the Karolinska Institutet, Sweden participated in this study. Information was derived from a self-answered questionnaire consisting of five items for career choice and six items for dental education. Chi-square test and Wilcoxon signed-rank test were used for comparison. Significant differences were detected for 10 questionnaire items between the two countries. Regarding motivation towards the career choice, 44% of Swedish students indicated interpersonal motives related to helping other people, whereas 32% of Japanese students indicated expectations of their family in the dental profession. As future career options, 64% of Japanese and 47% of Swedish students planned to work as general dentists. More Swedish students (37%) preferred specialisation than Japanese students (17%). Nearly three-quarters of the Swedish students were satisfied with the teaching faculty of their school, whilst only 32% of the Japanese students indicated content. The perspectives of dental students were different in Japan and Sweden. This study provides a description of the perspectives of Japanese and Swedish dental students and enables better understanding of career decision and dental curriculum issues.

Abstract
Fludarabine-based conditioning (FBC) was given to 24 patients and conventional myeloablative conditioning (MC) to 33 patients, most children, before hematopoietic stem cell transplantation (HSCT) for non-malignant diseases. The donors were human leukocyte antigen (HLA)-A, -B, -DRbeta1-identical related (33%) or unrelated (67%). In the FBC group, two grafts failed versus three in the MC group; all were successfully regrafted. Fever was more common in the MC patients (P=0.003). Bacteremia occurred in 25% of the FBC group and 50% in the MC group (P=0.1). In the FBC group, platelet engraftment was faster and transfusions were fewer (P<0.05). Mucositis and renal function were similar in the two groups. The MC group had higher maximum bilirubin (P=0.03) and less often normal spirometry (P=0.04) after HSCT. A 7-year-old girl in the MC group had permanent alopecia. No patients had severe acute graft-versus-host disease (GVHD). Chronic GVHD was rare. Complete donor CD3+ chimerism was more common in the MC group (P=0.01), but CD33+ engraftment was better with FBS (P=0.03). Treatment-related mortality was 4 and 15%, and 5-year survival was 89 and 85% in the FBC and MC groups. Although survival was similar, FBC is a promising alternative to MC in non-malignant disorders.

Abstract
UNLABELLED The child population in Sweden has changed dramatically during the last 20 years. Changes have also occurred within the Public Dental Service (PDS), regarding the provision of dental care to children and adolescents. All these changes may affect the referral pattern and provision of specialist dental care for children and adolescents. OBJECTIVES The primary aim of this study was to survey the services provided by specialists in paediatric dentistry in Sweden during 2003. A secondary aim was to compare the results with previous surveys. METHODS A Web-based survey was sent to all 34 specialist paediatric dentistry clinics and was answered by all clinics. Data were compared with results from the surveys performed in 1983, 1989, and 1996. RESULTS The number of paediatric dentists had been relatively constant over the last 20 years, whereas the number of children referred to paediatric dentists had increased by 28% since 1983. It was estimated that 1.3% of all children in Sweden are treated at a specialist paediatric dental clinic in 2003. Dental treatment need in combination with behaviour management problems (BMP) was the main reason for referral and occurred in 37% of all referrals. The proportion of medically compromised children/children with disabilities had increased from 6% in 1983 to 22% in 2003. The number of patients treated using sedation and general anaesthesia had increased since 1983, and particularly since 1996. CONCLUSIONS Despite improvements in dental health among children and adolescents in Sweden during the last 20 years, an increasing number of children are referred for specialist paediatric dental treatment. There is an urgent need to increase the number of specialist paediatric dentists in Sweden in order to ensure the continuation of high quality of dental care for children and adolescents.

Abstract
AIM This was to investigate the attitudes of Swedish general dental practitioners (GDPs) to pain perception in children and adolescents using a questionnaire survey. Their practice of pain control for dental treatment were also investigated. METHODS A questionnaire was sent to a random sample of 700 Swedish GDPs. Of these 421 (61%) were included in the analysis. RESULTS About half of the dentists were of the opinion that children have difficulties in telling the difference between pain and discomfort and one third thought that young children report pain with some or great uncertainty. Swedish dentists tend to under use both local analgesia, analgesics and sedatives for pain management during dental treatment. Many dentists found it stressful to give local analgesia to preschool children. The results also showed that a group of dentists, about 35%, were more indifferent to their patient's experiences of pain and psychological management. Despite these results, experienced Swedish GDPs find little need for continuing education in pain management and local analgesia. CONCLUSIONS Swedish GDPs under use local analgesia, analgesics and sedatives during dental treatment of children and adolescents. There is need for continuing education concerning pain management and an intensified discussion of attitudes to pain and pain management when treating children and adolescents.

Abstract
AIM The present study was designed to investigate whether a logbook helps undergraduate students to develop the ability to self-reflect and to increase their self-awareness. METHODS A logbook was introduced to 54 dental students in their fourth year of education at the beginning of the paediatric dentistry course. The students filled in a questionnaire on learning styles at the start of the course and after 12 months. RESULTS The results showed that at the end of the course significantly fewer students wished to be given detailed instructions to solve problems. Significantly more students felt able to expose both their weaknesses and strengths in clinical competence in the presence of their teachers. Students who reported a good knowledge of their own clinical skills found feedback from instructors more constructive compared with those who reported less good knowledge. CONCLUSION For a large group of students, the logbook stimulated self-reflection, learning from personal clinical experience, and an increase in knowledge about their weaknesses and strengths in clinical competence.

Abstract
A 3-week-old boy was diagnosed with congenital osteopetrosis. He underwent a bone marrow transplant at 6 weeks of age. At 3 years of age the primary teeth had all erupted, but the canines and the first molars totally lacked root development. The teeth were smaller in size and had evidence of both enamel hypomineralization and hypoplasia. In the permanent dentition, multiple missing teeth were found. The incisors were conical and the mandibular laterals were extremely small. All permanent teeth had normal eruption. This case shows that dental development and eruption of teeth can be reconstituted in a child with congenital osteopetrosis. Bone marrow transplantation induces normalization of osteoclast function, which is a prerequisite for normal dental development and eruption of teeth.

Abstract
Children treated for childhood cancers with both radiation and chemotherapy often exhibit disturbances in dental development. A retrospective analysis of treatment outcome in 10 orthodontically treated children was performed. A questionnaire was sent to each child's orthodontist, and 5 orthodontists reported that the patient's medical condition influenced their choice of treatment plan. Three orthodontists, all treating patients with severely disturbed root development, reported using lighter forces than they used with the average patient. With regard to complications related to orthodontic treatment, 1 of the 10 patients showed evidence of root resorption. In 4 of the 10 patients, the treatment result was judged to be unsatisfactory. This study showed that, although ideal treatment results were not always achieved, orthodontic treatment did not produce any harmful side effects in children who are long-term survivors of childhood cancer.

Abstract
OBJECTIVE The purpose of this report is to document a newly encountered oral side effect of targeted radiotherapy with iodine 131-metaiodobenzylguanidine ([(131)I]MIBG) in the treatment of neuroblastoma. STUDY DESIGN A 14-month-old girl was diagnosed with stage 4 neuroblastoma. After completion of chemotherapy, the tumor showed no signs of regression; treatment with 3700 MBq [(131)I]MIBG was therefore decided on, 8 months after diagnosis. RESULTS Fourteen days after infusion of MIBG, severe oral mucositis was diagnosed, with a generalized erythema involving the mucous membranes of the hard and soft palate, buccal mucosa, and upper and lower lips. The gingiva exhibited a general linear erythema. CONCLUSIONS Visualization of the salivary glands on [(123)I]MIBG images suggests that accumulation of radiolabeled MIBG in the salivary glands may be related to sympathetic innervation.

Abstract
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
Total body irradiation (TBI) at bone marrow transplantation (BMT) is shown to cause salivary gland dysfunction in children. The aim of the investigation was to study the function of major salivary glands in long-term surviving children following treatment with TBI, using salivary gland scintigraphy (SGS). Thirteen patients (seven male, six female), who had received TBI before the age of 13 years and survived more than 4 years, participated in the study. A reference group of 10 patients (nine male, one female) was examined shortly before they were to undergo BMT. The mean age was 14.1 +/- 4.1 years in the TBI-treated group and 12.8 +/- 5.9 years in the reference group. Unstimulated and stimulated whole salivary secretion rates were measured for 15 and 5 min, respectively, before SGS was performed. The percentage of stimulated secretion was 44.7 +/- 18.1% in the TBI-treated group compared to 58.4 +/- 13.0% in the reference group (P = 0.0438). Slower reaccumulation after excretion was found in the TBI-treated patients compared to the reference group (P = 0. 0300). The function of the major salivary glands in long-term survivors treated with TBI at BMT before the age of 13 years was found to be diminished, as shown by the reduced trapping rate and reduced emptying capacity, compared to prior to BMT.

Abstract
OBJECTIVES To study the correlation between whole salivary secretion rates and different variables from the radionuclide time-activity curve and to determine a reliable region for background correction in salivary gland scintigraphy. METHODS Salivary gland scintigraphy (SGS) was performed before bone marrow transplantation or more than 4 years later in 23 patients aged 13.5 (s.d. 4.9) years. Unstimulated and stimulated whole salivary secretion rates were measured before SGS. Six different methods for background correction were evaluated. RESULTS The unstimulated secretion rate was significantly correlated (P < 0.05) with the percentage stimulated secretion (S) and reaccumulation-slope (RS) after stimulation. The stimulated secretion rate was significantly correlated with RS, S and down-slope (DS). The temporal region above the parotid glands and the area above the thyroid gland was used for subtraction of background radiation for the parotid and submandibular glands respectively showed a strong correlation between repeated measurements of the variables analysed. The mean maximum uptake was 0.73-1.34% of total dose injected. CONCLUSIONS The salivary scintigraphic variables which correlated more strongly with salivary secretion rates were RS, S and DS. The temporal region above the parotid gland and the area above the thyroid gland can be used reliably for correction background radiation in the analysis of the time-activity curve in SGS of the parotid and submandibular glands respectively.

BACKGROUND The aim of the present investigation was to evaluate whether the subjective symptoms of dry mouth in long-term-surviving pediatric bone marrow transplant (BMT) patients are associated with low unstimulated salivary secretion rates (USSR) and with stimulated whole salivary secretion rates (SSSR). METHODS Fifty-three patients surviving > or =2 years after pediatric allogeneic BMT were included. USSR, SSSR, and the change in salivary secretion rates since the previous year were estimated. A questionnaire regarding subjective symptoms of xerostomia was answered. RESULTS The mean USSR and SSSR were 0.24+/-0.17 and 0.90 +/- 0.58 ml/min, respectively. Salivary gland dysfunction, defined as USSR < or =0.1 ml/min or SSSR < or =0.5 ml/min, was present in 35% of the patients. Seventy-nine percent of the patients expressed one or more symptom of dry mouth, and 49% gave at least two answers indicating dry mouth. The number of complaints increased with age at examination (P<0.05). Both USSR (P<0.01) and SSSR (P<0.01) were inversely correlated to the total number of complaints of xerostomia. A reduction in SSSR compared with the year before was correlated to two or more complaints of xerostomia (P<0.01). The presence of dry mouth at night or on awakening was indicative of both low USSR (P<0.01) and SSSR (P<0.001). Patients reporting dryness during the day had significantly lower SSSR (P<0.05). CONCLUSION The expression of subjective complaints of xerostomia among long-term surviving pediatric BMT patients is correlated to salivary gland dysfunction and age. It is very important to identify these patients with salivary gland dysfunction to relieve their symptoms and prevent secondary complications.

Abstract
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
The development of periodontal disease in Down syndrome adolescents (n = 34) was studied clinically and on intraoral radiographs during a 7-yr period. The occurrence of gingival inflammation (GBI), pathological periodontal pockets (>4 mm), sub- and supragingival calculus, alveolar bone height, alveolar bone loss, and the occurrence of the periodontal pathogens Actinobacillus actinomycetemcomitans, Capnocytophaga, and Porphyromonas gingivalis in subgingival plaque were determined. Of the subjects, 41% had one or more pathological periodontal pockets at baseline compared to 65% at follow-up. At the baseline examination, 35% of the individuals exhibited alveolar bone loss compared to 74% at the follow-up. The median value of sites with alveolar bone loss increased from 0 to 1, the new lesions mainly being located in the incisor region. The estimated annual reduction of alveolar bone height in each subject was 0.04 mm on average. The occurrence of the periodontal pathogens A. actinomycetemcomitans, Capnocytophaga, and P. gingivalis in subgingival plaque did not differ between baseline and follow-up. The results of the present study indicate that the frequency of periodontitis, mainly located on the lower incisors, markedly increased during a 7-yr period in Down syndrome individuals, although the severity and progression was limited compared to what has previously been described.

Abstract
A Portfolio of Qualifications for academic appointments at the Karolinska Institutet has been developed to define more clearly the competence and qualifications which are given high priority for academic appointments at the Karolinska Institutet. The major fields of application are for new appointments and promotions, providing guidelines for the individual for improving his/her proficiency, and as a basis for determining individual salary rates. Four portfolios have been developed, a pedagogical, a clinical, a scientific, and a leadership, development and workplace relations portfolio. Attached to the portfolios are assessment forms. We consider the Qualifications Portfolio to be a reflection of changes in attitudes and values at the Karolinska Institutet. The system offers a method for the recognition of faculty productivity in different dimensions. This may be beneficial for the university in view of the increasing diversity and complexity of academic institutions. The Qualifications portfolio can be obtained from the world wide web, http:/(/)www.ki.se/ki/merit.se.html (in Swedish), http:/(/)www.ki.se/ki/merit.html (in English).

Abstract
Craniofacial growth was evaluated 3 years after termination of growth hormone (GH) therapy in ten Down syndrome (DS) children. The control group consisted of 16 age-matched children with DS. The treatment started at 6-9 months of age, and the duration was 36 months. There were no statistically significant differences in craniofacial development between DS children treated with GH or DS children not treated. In conclusion, the results of this study indicate that GH therapy for 36 months in children with DS did not change the craniofacial morphology compared to a group of DS children not given GH.

Abstract
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.

Abstract
Periodontal conditions and salivary levels of immunoglobulins sIgA, IgM, and IgG subclass distribution and albumin, quantified by enzyme-linked immunosorbent assay, were determined in 20 patients with Down syndrome and 19 healthy controls. Gingival inflammation was more extensive (P < 0.05) among Down syndrome subjects compared to controls as well as the occurrence of periodontal pockets (> 4 mm) (P < 0.05). The immunoglobulin levels of sIgA, IgM, the sum of IgG subclasses, and the concentration of albumin did not differ significantly between the 2 groups. However, the proportion of IgG1 expressed as percentage of the sum of total IgG was significantly higher (P < 0.01) in the Down syndrome group compared to controls. On the contrary, the proportion of IgG2, IgG3, and IgG4 subclasses in saliva did not differ between the 2 groups. The results indicate an altered distribution of IgG subclasses in saliva, with a higher proportion of IgG1 in Down syndrome individuals compared to controls.

Abstract
The concept of a merit profile has been evolved at Karolinska Institute in Stockholm, whereby not only research achievements but also teaching, administrative and clinical skills and experience are each given merit ratings to produce an individual profile. This approach is based on the notion that all of these fields of activity constitute integregal facets of a scat of higher learning in medicine, and that a candidate's relative merits in each of these areas should be seen not only in relation to the overall academic goals but also to practical, professional considerations. The merit profile is intended to be used in selection for appointments and promotion, and as a basis for the continued enhancement of individual competence, and salary review.

Abstract
Conditioning before bone marrow transplantation (BMT) with total body irradiation (TBI) and cyclophosphamide carries the risk of severe long-term complications. The aim of the present study was to determine absorbed doses in the craniofacial area during TBI, using thermoluminescent dosimeters for both in vivo techniques and phantom measurements. The results from the phantom study showed that the mean deviation from the reference dose varied between -5.1 and +11.1%. The superficial part of left parotid gland received 11.1 +/- 1.5% more radiation compared with the reference. In patients, deviations from the reference dose varied in individual patients between -22.4 and +20.1% in various intra-oral sites. Since a small increase in dose can result in a significantly increased risk of pathology, the observed dose inhomogeneities for structures receiving tangentially directed radiation therapy, such as the parotid glands, may contribute to salivary dysfunction after TBI.

Abstract
The aim of this investigation was to study dental maturity in healthy prepubertal children of short stature (height<-2 SD), with or without growth hormone (GH) deficiency, compared to healthy controls. The GH-deficient group (GH level<10.0 microg/l) included 29 children (11 female, 18 male) with a mean age of 10.2+/-2.2 years. The GH non-deficient group consisted of 17 children (5 female, 12 male) with a mean age of 8.5+/-2.1 years. All the children were evaluated for serum concentrations of IGF-1, alkaline phosphatase (ALP), triiodthyronin (T3), thyroxine (T4), thyroid-stimulating hormone (TSH), and fasting plasma insulin; height and bone age were also recorded. Dental maturity was determined from panoramic radiographs. The mean difference between the dental and chronological ages was -0.67+/-0.89 years in the GH-deficient group compared to 0.23+/-1.07 years in their controls: in the GH non-deficient group the difference was -0.95+/-0.82 years compared to controls 0.16+/-1.06 years in their controls. Compared to chronological age, both bone and dental age were lower in the GH-deficient and GH non-deficient groups. It is concluded that children of short stature, both GH-deficient and GH non-deficient. exhibit a delayed dental age compared to their chronological age- and sex-matched controls. A multiple stepwise regression analysis showed that the sitting height and GH level were the only significant factors associated with dental maturity.

Abstract
Sixty-one children with a median age of 6 years (range 1-16) were given prophylaxis/therapy for 78 courses of treatment with liposomal amphotericin (AmBisome) and were reviewed retrospectively. Thirty-six received allogeneic bone marrow, 22 a liver transplant, 2 kidneys and 1 a liver and kidney. AmBisome was given as prophylaxis in 30 episodes, as treatment for suspected invasive fungal infections (IFI) in 33 and for a verified IFI in 15. AmBisome prophylaxis was given for a median of 14 days in a dose of 1 mg/kg/day. The median dose of AmBisome was 2.1 mg/kg/day (range 0.9-5.0). The median duration of therapy was 10 days in children with suspected IFI and 20 days in children with verified IFI. The total dose ranged from 0.025 g up to a maximum of 3.95 g. Proven and probable side effects of AmBisome were a decrease in the level of serum potassium (30/78 cases), renal toxicity (22), an increase in the alkaline phosphatases (24), back pain (2), fever and abdominal pain (2), anaphylactic reaction (1), an increase in the bilirubin level (1), nausea (1), chest pain (1) and fever (1). Of 31 children with suspected IFI, fever disappeared in 21 (68%). In 14 verified or suspected IFI cases treated for 5 days or more, the clinical cure rate was 12 (86%). Eradication of fungi from a deep site was verified in 8/10 and the survival rate from 1 1/2 years to more than 7 years was 7/12 (58%). We conclude that AmBisome was well tolerated as prophylaxis and therapy in transplanted children, few acute toxic side effects were seen and the cure rate in verified IFI was high.

Abstract
Salivary function, dental caries and caries-associated salivary microorganisms were investigated in children undergoing BMT during a 4-year longitudinal study. Fourteen children were conditioned with CY and TBI and 12 with CY with or without BU. Four years after BMT the mean salivary secretion rate was 1.3 +/- 0.7 ml/min in the chemotherapy group, compared to 0.7 +/- 0.5 in the TBI/CY group (P < 0.05). The mean salivary secretion rate fell from 0.9 +/- 0.5 ml/min before TBI to 0.2 +/- 0.1 after 3 months (P < 0.01), 0.3 +/- 0.3 ml/min after 6 months (P < 0.01) and 0.5 +/- 0.6, 1 year after TBI (P < 0.05). Mean reduction in stimulated salivary flow 3 months after TBI was 78% in the TBI/CY group compared to 36% in the chemotherapy group (P < 0.05). Children conditioned with chemotherapy showed an increased salivary flow compared to baseline; this was not found in TBI-treated children, suggesting that damage to the salivary glands may be permanent. Four years after BMT, children conditioned with TBI had significantly higher counts of mutans streptococci (P < 0.05) and lactobacilli (P < 0.01) compared to age-matched controls. However, the prevalence of dental caries did not differ between children conditioned with TBI, chemotherapy and healthy controls.

Abstract
Bone marrow transplantation (BMT) in childhood has improved the survival for children with leukaemia, severe aplastic anaemia and some metabolic disorders. However, transplant procedures are associated with a high incidence of deleterious long-term complications. This study included 49 children, conditioned according to the Seattle protocols. Follow-up oral examinations were performed 1 year after BMT. Forty risk factors that may have influenced a low stimulated salivary secretion rate (SSSR) were studied. An SSSR < or = 0.5 ml/min, 1 year after BMT was regarded as the event. One year after BMT, the mean SSSR was 0.5 +/- 0.4 ml/min in children conditioned with total body irradiation (TBI) compared to 1.0 +/- 0.5 ml/min in non-irradiated children (P = 0.0013). Significant predictors for low SSSR in multivariate analysis were: conditioning with TBI (P = 0.0023), recipient female sex (P = 0.0121) and recipient seropositivity for between three and four herpes viruses (P = 0.0157).

Abstract
A radiographic dental examination was performed in 16 children conditioned with total body irradiation (TBI) and cyclophosphamide (CY) prior to bone marrow transplantation (BMT), and in 52 children treated with multiagent chemotherapy. For each child, three age- and sex-matched healthy controls were selected. Evaluation of disturbances in dental development and tooth size was based on planimetric measurements of mandibular teeth on panoramic radiographs. Short V-shaped roots were diagnosed in 94 per cent of the children treated with TBI/CY compared with 19 per cent in the chemotherapy group (P < 0.001). Children receiving TBI/CY also exhibited a pronounced reduction in tooth size compared with the controls. Reductions varied from 19 per cent in incisors to 39 per cent in the second molars. In the chemotherapy group the corresponding values were 7 and 15 per cent respectively. When comparing crown/root ratios, the indices for incisors, canines (P < 0.05) and molars (P < 0.01) in the BMT group were significantly higher than the corresponding values in the control group. This indicates that the reduction in root size was more pronounced than the reduction in crown size. The premolars in the BMT group exhibited a similar reduction in crown and root size. All developing teeth were affected by multiagent chemotherapy and radiation therapy. The most severe disturbances were found in children treated with TBI/CY at a young age.

Abstract
Oral carriage of Candida albicans was studied in 55 children and adolescents with Down's syndrome (DS), aged between 7 months and 20 years 6 months, and compared with an age- and sex-matched control group of subjects. Twenty-two of the DS subjects were diagnosed as having congenital cardiovascular malformations. Compared to controls, the DS subjects were more prone to infections. The number of subjects colonized with C. albicans in the oral cavity was significantly higher in the DS group (69%) than in the control group (35%). Colonization with C. albicans and simultaneous erythematous or white pseudomembranous lesions of the oral mucosa were diagnosed in 22 (40%) of the DS groups and in only one of the control group. In both the DS and the healthy control subjects the frequency of colonization with C. albicans was positively correlated to age. The DS subjects were significantly more densely colonized by C. albicans than the controls. Abnormalities of the immune response in DS children may contribute to the increased oral carriage of C. albicans.

Abstract
The effect of palatal plate therapy on oral dysfunction in children with Down syndrome was studied during a 1-year period. Twenty-nine subjects with a mean age of 24 months were randomized to a test group or to a control group. The variables concerning orofacial muscle function--that is, "closed mouth', "tip of the tongue visible', "open mouth', "inactive protrusion of the tongue', and "active protrusion of the tongue'--were monitored by video recordings. After 12 months of therapy the mean duration of the factor "closed mouth' was significantly longer (p < 0.001) and "inactive protrusion of the tongue' significantly shorter (p < 0.001) in the test group than in the control group. The results indicate that in children with Down syndrome, palatal plate therapy may be a valuable complement to a training program for improving orofacial muscle function.

Abstract
The present study is a part of a prospective, longitudinal investigation of caries development in children (n = 692) living in the southern suburbs of Stockholm. The aim was to evaluate, longitudinally, the caries-predictive ability of variables describing social and immigrant background, dietary habits, microbial and oral hygiene factors, and fluoride exposure in children at 1 and 2.5 years of age with respect to caries development before the age of 3.5. The predictors for caries development in children before 2.5 years of age were mutans streptococci (p < 0.01), immigrant background (p < 0.01), and consumption of candy (p < 0.01). The predictors for developing manifest caries between 2.5 and 3.5 years of age were mutans streptococci (p < 0.001), mother's education (p < 0.001), immigrant background (p < 0.01), and consumption of candy (p < 0.05) and sugar-containing beverages (p < 0.05). The caries incidence at 2.5 years of age as well as the caries increment between 2.5 and 3.5 years of age were significantly higher in children with immigrant background compared to non-immigrants. This study indicates that the possibility of identifying children at risk for caries development increases longitudinally from 1 to 3.5 years of age and there was a synergistic effect between age and each predictor.

Abstract
Among 42 consecutive recipients of unrelated marrow were 39 HLA-A, -B, -DR identical, matched unrelated donors (MUD) and three with one HLA antigen mismatch. The majority were genomically typed for DRB, DQA, DQB and DPB. The recipients of MUD marrow were compared with 39 recipients of marrow from HLA-identical siblings with similar diagnoses, disease status and age. Each group included 24 patients with hematological malignancies, 6 with severe aplastic anemia and 9 inherited disorders. Immunosuppression consisted of anti-thymocyte globulin (ATG; pre-BMT mainly to recipients of unrelated marrow), CsA and four doses of MTX. Grade I acute GVHD was treated with prednisolone 2 mg/kg. In a comparison of MUD marrow recipients and HLA-identical siblings 34 of 39 and 36 of 39 of the patients engrafted, respectively. Recipients of MUD marrow and HLA-identical siblings achieved 0.2 x 10(9) WBC/l on day 16 (median) and 14, respectively (P = 0.03). Furthermore, the recipients of MUD marrow needed more platelet transfusions (P = 0.04). The incidence of acute GVHD grade II-III was 15% in the MUD marrow recipients compared with 11% among the HLA-identical siblings. The 2-4 year cumulative incidence of chronic GVHD was 29% and 22% in the two groups, respectively. The overall 2-year survival was 59 and 78%, respectively. Among patients with CML in chronic phase or accelerated phase (n = 26), 2-year relapse-free survival was 79% in both groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Dietary habits, oral hygiene, fluoride exposure and occurrence of mutans streptococci were studied in 1-year-old children (n = 786) as well as the socio-economic and immigrant background of their parents. The purpose was to evaluate the predictive ability of variables studied in 1-year-old children that could be used to identify children at risk for early caries development. In a multivariate logistic regression analysis, the variables significantly associated with caries at 3.5 years of age were immigrant background (p < 0.001), mother's education (p < 0.001), consumption of sugar-containing beverages (p < 0.001), mutans streptococci (p < 0.05) and candy (p < 0.05). The probability of caries development was 87% when all the variables associated with caries were present at 1 year of age. The relative risk (odds ratio) of those children to develop manifest caries at 3.5 years of age was estimated to be 32 times higher than in the children where corresponding risk factors were not present. The results indicate that prediction at 1 year of age, built on risk factors associated with dental caries, can provide an indication of possible preventive interventions.

Abstract
The development of dental caries from the age of 2.5 to 3.5 years was studied longitudinally in 692 children living in the southern suburbs of Stockholm. The parents answered a structured questionnaire concerning the family's social and immigrant background as well as the dietary habits, oral hygiene and fluoride exposure of their children. Furthermore, the occurrence of mutans streptococci and lactobacilli was determined in samples taken from the tongue of the children, and the buffer capacity of the saliva was measured. At baseline examination, 11.3% of the children exhibited dental caries. At follow-up, 1 year later, decayed and/or filled surfaces were registered in 36.7% of the subjects. The majority of the new lesions were located on the occlusal surfaces of the second molar. Ninety-two percent of the children with caries at baseline developed new carious lesions during the 1-year period, compared to 29% of the children who were caries-free at baseline (p < 0.001). Of the lesions diagnosed at baseline as initial caries, 64% progressed to manifest lesions during the 1-year period. The study indicates that children with early caries development exhibit high caries progression as well as a high risk for further development of an extensive number of new carious lesions.

Abstract
The effect of growth hormone (GH) treatment on craniofacial development was studied in nine children exhibiting low growth velocity after bone marrow transplantation (BMT). Comparisons were made with seven BMT children who had not received GH. Two groups of age- and sex-matched healthy children served as controls for the respective patient groups. After an average observation period of 3.5 years, the BMT children not treated with GH exhibited significantly reduced mandibular length and alveolar height (p < 0.01). The increase in mandibular length was only 30% of that found in healthy controls. Maxillary growth was less affected by BMT treatment. In the GH treated group, no significant differences were found in craniofacial growth increments compared with controls. Although exogenous GH therapy in this group of children did not induce a catch-up growth, it appears to have prevented further loss in growth potential.

Abstract
Oral health and disturbances in dental development were studied in long-term survivors after antineoplastic therapy. Fifty-seven children treated with combination chemotherapy and 19 children treated with total body irradiation (TBI) prior to bone marrow transplantation (BMT) were examined. The variables studied were dental caries, salivary flow, salivary microbial counts, enamel disturbances, and disturbances in dental development. The results showed no increased caries experience in children treated with BMT or chemotherapy compared with controls. Children treated with BMT had a significantly lower salivary secretion rate of 0.7 +/- 0.4 ml/min, compared with 1.1 +/- 0.5 in the chemotherapy group, and 1.3 +/- 0.6 in the control group (P < 0.05). The clinical examination showed equal numbers of teeth affected by disturbances in enamel mineralization in the BMT and chemotherapy groups. A mean 15.9 +/- 8.2 teeth were affected by disturbances in root development in the BMT group compared with 1.2 +/- 1.6 in the chemotherapy group (P < 0.001). The results show that children who are long-term survivors of pediatric malignant diseases exhibit a wide range of disturbances in the oral cavity. In this study the most severe disturbances are found in children treated with total body irradiation prior to BMT.
