Abstract
With diagnostic and therapeutic advances, over 80% of children diagnosed with cancer become long-term survivors. As the number of childhood cancer survivors (CCS) continues to increase, dental practitioners become more likely to have CCS among their patients. CCS may develop late complications from damage caused by their cancer treatment to endocrine, cardiovascular, musculoskeletal, and other organ systems. These complications may surface decades after the completion of treatment. Adverse outcomes of childhood cancer treatment frequently involve oral and craniofacial structures including the dentition. Tooth development, salivary gland function, craniofacial growth, and temporomandibular joint function may be disturbed, increasing oral health risks in these individuals. Moreover, CCS are at risk of developing subsequent malignancies, which may manifest in or near the oral cavity. It is important that dental practitioners are aware of the childhood cancer history of their patients and have knowledge of potential late complications. Therefore, this narrative review aims to inform dental practitioners of late oral complications of cancer treatment modalities commonly used in pediatric oncology. Furthermore, selected common non-oral late sequelae of cancer therapy that could have an impact on oral health and on delivering dental care will be discussed.

Abstract
INTRODUCTION Currently, 1 out of 900 adults from the ages of 16 to 44 is a survivor of childhood cancer. The global rate of survival for all types of childhood cancer is close to 80% and progress in treatment and care continues to offer promising results. In the years following treatment, these children, just like other healthy children, should have access to orthodontic care in spite of their chronic health problems. OBJECTIVES A transverse epidemiological study was conducted at the Leon Bernard Cancer Treatment Center in Lyon in order to respond to these requests and to assist orthodontists with the therapeutic difficulties presented by these patients. Our objective was to identify the orthodontic treatment required for children 7 years old or older who received antineoplastic therapy with radiation of the cranio-cervico-facial region. RESULTS The results show that children who received radiation therapy in the cranio-facial region presented delayed growth, facial asymmetry in 74% of the cases, overbite and overjet increased respectively in 70% and 61% of the cases. Dental discrepancies in development were present in 83% of the patients who presented with stunted teeth, premature closing of the apices and hypoplasias. We found sialopathy such as reduced saliva flow rate. Finally, considerable treatment was necessary in 61% of the cases and moderate treatment for 17% of the cases, because of missing teeth, retained deciduous teeth or an increased overjet.

Abstract
BACKGROUND The current study was performed to describe frequencies and risk factors of altered oral health and odontogenesis in childhood cancer survivors. METHODS In total, 9308 survivors who were diagnosed between 1970 and 1986 and 2951 siblings from the Childhood Cancer Survivor Study completed a survey that contained oral-dental health information. The authors analyzed treatment impact, socioeconomic data, and patient demographics on dental outcomes using univariate and multivariate logistic regression models to estimate odds ratios (ORs). RESULTS In multivariate analysis, survivors were more likely to report microdontia (OR, 3.0; 95% confidence interval [95% CI], 2.4-3.8), hypodontia (OR, 1.7; 95% CI, 1.4-2.0), root abnormalities (OR, 3.0; 95% CI, 2.2-4.0), abnormal enamel (OR, 2.4; 95% CI, 2.0-2.9), teeth loss>or=6 (OR, 2.6; 95% CI, 1.9-3.6), severe gingivitis (OR, 1.2; 95% CI, 1.0-1.5), and xerostomia (OR, 9.7; 95% CI, 4.8-19.7). Controlling for chemotherapy and socioeconomic factors, radiation exposure of >or=20 Gray to dentition was associated significantly with an increased risk of >or=1 dental abnormality. Dose-dependent alkylating agent therapy significantly increased the risk of >or=1 anatomic/developmental dental abnormalities in survivors who were diagnosed at age<5 years (OR, 1.7, 2.7, and 3.3 for alkylating agent scores of 1, 2, and 3, respectively). CONCLUSIONS Radiation and chemotherapy were independent risk factors for adverse oral-dental sequelae among childhood cancer survivors. The authors concluded that patients who received receiving alkylating agents at age<5 years should be closely monitored.

Abstract
The purpose of our study was to describe the types and frequencies of altered dental development in pediatric patients preparing for bone marrow transplantation (BMT). Retrospective review of the medical records and panoramic radiographs of all patients who underwent BMT at St Jude Children's Research Hospital between 1990 and 2000 for whom pre-BMT dental examination and panoramic radiography records were available. All patients were treated on institutional protocols. We recorded patient demographics and radiographic evidence of microdontia, hypodontia, taurodontia, root stunting, caries, enamel pearls, and pulpal calcifications. The 259 patients identified (150 male and 109 female) had a median age of 12.82 years (range, 3.18-25.93 years) at the time of BMT. In total, 203 were Caucasian, 38 were African-American, and 18 were of other races. In all, 150 (57.9%) had abnormal dentition. The most common dental abnormalities were caries (n=84), pulpal calcifications (n = 34), and dental extractions (n = 33). Developmental abnormalities occurred less frequently: taurodontia (n = 8), hypodontia (n = 10), microdontia (n = 11), and root stunting (n = 11). Dental abnormalities are prevalent in children undergoing BMT. Pre-transplant oral hygiene and dental examination should be standard care in order to minimize potential sites of infection.

A retrospective review of the medical records and panoramic radiographs of all patients who underwent BMT at St Jude Children's Research Hospital between 1990 and 2000, for whom pre-BMT and post-BMT dental examination and panoramic radiography records were available, is presented. All patients were treated on institutional protocols. We recorded patient demographics and radiographic evidence of microdontia, hypodontia, taurodontia, root stunting, caries, enamel pearls, dental restorations/extractions and pulpal calcification. The 99 patients identified (52 males, 47 females) had a median age of 13.5 years (range, 3.4-25.9 years) at the time of BMT. In all, 73 were Caucasian, 15 were African-American, and 11 were of other races. The frequency of radiographically evident root stunting in permanent teeth was significantly increased after BMT (P<0.001), but there was no significant change in the frequency of other dental abnormalities after BMT. Dental abnormalities are prevalent in survivors of childhood BMT, but only root stunting appeared to progress with BMT.

Abstract
Evaluations of endocrine function following hematopoietic cell transplantation demonstrate that the endocrine function abnormalities observed are related to the type of transplant preparative regimen received. Children given high dose cyclophosphamide (CY) only have normal thyroid function, normal growth and development. Children who received a busulfan (BU) plus CY preparative regimen usually have normal thyroid function, normal prepubertal growth, delayed or absent pubertal development, and blunted post-pubertal growth. Recipients of preparative regimens containing total body irradiation may be anticipated to have some thyroid dysfunction, impaired growth rates and delayed or absent pubertal development. Post-pubertal teens and young adults are likely to have gonadal function recover if they received a preparative regimen with CY only but are likely to have primary gonadal failure if they received a preparative regimen with BU or total body irradiation. Individuals whose gonadal function becomes normal have become parents of normal children. All patients who receive a marrow transplant should be followed long-term for development of endocrine function abnormalities.

Abstract
In addition to anti-tumor effects, ionizing radiation causes damage in normal tissues located in the radiation portals. Oral complications of radiotherapy in the head and neck region are the result of the deleterious effects of radiation on, e.g., salivary glands, oral mucosa, bone, dentition, masticatory musculature, and temporomandibular joints. The clinical consequences of radiotherapy include mucositis, hyposalivation, taste loss, osteoradionecrosis, radiation caries, and trismus. Mucositis and taste loss are reversible consequences that usually subside early post-irradiation, while hyposalivation is normally irreversible. Furthermore, the risk of developing radiation caries and osteoradionecrosis is a life-long threat. All these consequences form a heavy burden for the patients and have a tremendous impact on their quality of life during and after radiotherapy. In this review, the radiation-induced changes in healthy oral tissues and the resulting clinical consequences are discussed.

Abstract
Treatment regimes for childhood cancer are known to affect the root development in the long-term survivors (LTS) but the available the data is subjective in nature with very few quantitative data in the literature. This study aimed to quantify the root surface area (RSA) of mandibular teeth in LTS compared with controls and relate this to the treatment regime and also to the age at which the cancer was diagnosed. Panoramic radiographs were obtained from 69 LTS and an equal number of appropriately matched healthy controls. RSA were calculated using Computer Linked Image Analysis. RSA in the LTS were found to be significantly smaller as compared with controls. Also, RSA were the least in those LTS who had Total Body Irradiation followed by Bone Marrow Transplantation (TBI/BMT) compared with other treatment regimes, the difference being statistically significant for all teeth studied. There was no relationship between the RSA and the age at which the cancer was diagnosed. Smaller root areas have implications for the oral health of LTS, as bone loss around such teeth will compromise further their periodontal support thus jeopardising the long-term survival of the tooth.

Abstract
Late effects following HSCT are related to either the transplant process or to the transplant preparative regimen. Problems related to the transplant process include delayed recovery of the immune system and chronic GVHD. Chronic GVHD presents between 3-14 months post-HSCT in approximately 20% of matched sibling transplants and 40% of matched unrelated donor recipients. Most commonly involved sites are skin, mouth, liver, gastrointestinal tract, and eye. Patients with platelet count < 100,000/ml and receiving cortocosteroid therapy at day 80 with any clinical manifestations of chronic GVHD require prolonged immune suppressive therapy with prednisone, cyclosporine +/- other agents. Treatment should be administered until all clinical and pathological signs and symptoms of chronic GVHD have resolved which may take one to several years. Problems related to the transplant preparative regimen include those involving the endocrine system, eyes, lungs, bone, and development of secondary malignancies. Endocrine deficiencies include growth failure with growth hormone (GH) deficiency, overt hypothyroidism, primary gonadal failure, Type 1 or Type 2 diabetes, and exocrine pancreatic insufficiency. These problems develop at any time post-HSCT, but usually occur within the first few years and should be treated with appropriate hormone supplementation. Eye problems are primarily related to development of cateracts secondary to total body irradiation (TBI) or prolonged corticosteroid use. Cateracts developing after fractionated frequently do not require removal. Pulmonary problems may be due to bronchiolitis obliterans (BO) or to restrictive lung disease. BO may be associated with chronic GVHD and may respond to chronic GVHD therapy. Restrictive lung disease does not occur for many years after HSCT. There is not therapy for this problem. Development of decreased bone mineral density (BMD) is related to GH deficiency and/or corticosteroid therapy. Treatment includes withdrawal of corticosteroids, administration of GH and calcium, Vitamin D and antiresorptive agents. All malignant disease survivors are at risk for development of secondary malignancies, including survivors of HSCT. Recipients of TBI are at highest risk as are children. All pediatric and adult survivors of HSCT should be followed for their life-time for development of delayed effects of transplantation.

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
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
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
Antineoplastic therapy causes developmental disturbances in the dental enamel and root if children are treated during tooth development. Increased caries activity has also been reported. The effect of anticancer therapy on the function of the masticatory system (i.e. jaws, dentition, masticatory muscles) is not well known. A case report of a 9-year-old girl with right auricular rhabdomyosarcoma is presented. She received irradiation of 50 Gy to the right auricular area and chemotherapy. A year and a half after cessation of cancer therapy, she was disease free and the clinical stomatognathic examination combined with electromyogram (EMG) registration of the masseter and temporal muscles and magnetic resonance imaging (MRI) examination of the temporomandibular joints (TMJ) revealed a strongly restricted mouth opening capacity, painful right TMJ, and flattened head of the right mandibular condyle. Muscle atrophy in the right masseter muscle was clearly visible but EMG activities of the masseter and temporal muscles, however, were higher on the right than on the left. More severe developmental defects, and worse gingival and cariological health were observed on the right side than on the left side. She developed 12 carious lesions and all the lesions were on the right maxilla or mandible or on anterior teeth. The left side was not affected. Intensive prophylactic dental care after cancer treatment is important in order to prevent caries and gingival inflammation. Stomatognathic treatment (i.e. management of occlusal and dysfunctional problems) may improve the mouth opening capacity and relieve pain.

Abstract
There has been a dramatic improvement in the treatment of both allogeneic and autologous stem cell transplants, especially in children and young adults. However, attempts to apply more intensive conditioning treatments to the more refractory pediatric malignancies have also increased the risks of deleterious consequences. This review examines the risks, and reports important variations in the toxic effects of using different conditioning techniques.
