Salivary and Dental Complications in Childhood Cancer Survivors Treated With Radiation Therapy to the Head and Neck: A PENTEC Comprehensive Review. Int J Radiat Oncol Biol Phys 2024; 119:467-481. [PMID: 34074567 DOI: 10.1016/j.ijrobp.2021.04.023] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Revised: 03/14/2021] [Accepted: 04/21/2021] [Indexed: 12/24/2022]
Abstract
PURPOSE Radiation therapy (RT) to the head and neck (H&N) region is critical in the management of various pediatric malignancies; however, it may result in late toxicity. This comprehensive review from the Pediatric Normal Tissue Effects in the Clinic (PENTEC) initiative focused on salivary dysfunction and dental abnormalities in survivors who received RT to the H&N region as children. MATERIALS & METHODS This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. RESULTS Of the 2,164 articles identified through a literature search, 40 were included in a qualitative synthesis and 3 were included in a quantitative synthesis. The dose-toxicity data regarding salivary function demonstrate that a mean parotid dose of 35 to 40 Gy is associated with a risk of acute and chronic grade ≥2 xerostomia of approximately 32% and 13% to 32%, respectively, in patients treated with chemo-radiation therapy. This risk increases with parotid dose; however, rates of xerostomia after lower dose exposure have not been reported. Dental developmental abnormalities are common after RT to the oral cavity. Risk factors include higher radiation dose to the developing teeth and younger age at RT. CONCLUSIONS This PENTEC task force considers adoption of salivary gland dose constraints from the adult experience to be a reasonable strategy until more data specific to children become available; thus, we recommend limiting the parotid mean dose to ≤26 Gy. The minimum toxic dose for dental developmental abnormalities is unknown, suggesting that the dose to the teeth should be kept as low as possible particularly in younger patients, with special effort to keep doses <20 Gy in patients <4 years old.

Dental caries and dental developmental defects as adverse effects of antineoplastic treatment in childhood cancer survivors. Eur Arch Paediatr Dent 2023:10.1007/s40368-023-00789-z. [PMID: 36906732 DOI: 10.1007/s40368-023-00789-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Accepted: 02/23/2023] [Indexed: 03/13/2023]
Abstract
PURPOSE To evaluate the prevalence of dental caries and dental developmental defects (DDD) in childhood cancer survivors (CCS) and identify disease and treatment-related risk factors. METHODS CCS aged up to 21 years, diagnosed with a malignancy before the age of 10 years and in remission for at least one year were included. Data were collected from patients' medical records and through a clinical examination where presence of dental caries and prevalence of DDD were recorded. Fisher's exact test was used to assess possible correlations and multivariate regression analysis to determine risk factors for defect development. RESULTS Seventy CCS with a mean chronological age of 11.2 years at the time of examination, mean age at cancer diagnosis of 4.17 years, and a mean post-treatment follow-up time of 5.48 years were included. Mean DMFT/dmft was 1.31, with 29% of survivors presenting with at least one carious lesion. Younger patients on the day of examination and patients treated with higher radiation dose, showed significantly higher prevalence of dental caries. The prevalence of DDD was 59%, with demarcated opacities being the defect most commonly observed (40%). Age at dental examination, diagnosis, age at diagnosis, and time that have elapsed since the end of treatment were the factors significantly affecting its prevalence. Regression analysis revealed that age at examination was the only factor significantly associated with the presence of coronal defects. CONCLUSION A great number of CCS presented with at least one carious lesion or a DDD, with the prevalence being significantly associated with various disease-specific characteristics, but age at dental examination the only significant predictor.

Front Pediatr 2022; 10:836708. [PMID: 35281236 PMCID: PMC8907975 DOI: 10.3389/fped.2022.836708] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Accepted: 01/20/2022] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Developmental Defects of Enamel (DDE) is a pathology of the teeth that can greatly alter the quality of life of patients (hypersensitivity, esthetic issues, loss of function, etc.). The acquired DDE may occur as a result of a wide range of acquired etiological factors and his prevalence of this pathology may reach up to 89.9%. The main objective of this research was to identify and analyze, in current literature, the factors related to acquired DDE, in order to propose a general theory about the mechanisms involved. METHODS The search of the primary literature was conducted until [December 31, 2021]. Our search strategy uses the Pubmed/MEDLINE database and was structured around 3 terms ["Development," "Defect," and "Enamel"]. To be included, references had to be primary studies, written in English. Exclusion criteria were reviews, in vitro, animal, genetic or archeology studies, and studies focused on clinical management of DDE. One hundred and twenty three articles were included in this scoping review: 4 Randomized clinical trials, 1 letter, 5 cases reports, 2 fundamentals studies, and 111 observational studies (33 Cross-sectional studies, 68 Cohort study and 10 Case-control study). The quality of evidence was assessed using the PEDro scale for clinical trials, the Newcastle-Ottawa scale for observational studies, and a published tool to assess the quality of case reports and case series. RESULTS A scoping review of the literature identified 114 factors potentially involved in acquired DDE. The most frequently encountered pathologies are those causing a disorder of calcium homeostasis or a perturbation of the ARNT pathway in mother or child. The link between the ARNT pathway and metabolism deficiency in uncertain and needs to be defined. Also, the implication of this mechanism in tissue impairment is still unclear and needs to be explored. CONCLUSIONS By identifying and grouping the risk factors cited in the literature, this taxonomy and the hypotheses related to the mechanism allow health practitioners to adopt behaviors that limit the risk of developing aDDE and to set up a prevention of dental pathology. In addition, by reviewing the current literature, this work provides guidance for basic research, clinical studies, and literature searches.

Abstract
PURPOSE To investigate oral and dental late effects in survivors of childhood brain tumors medulloblastoma (MB) and central nervous system supratentorial primitive neuroectodermal tumor (CNS-PNET). METHODS This cross-sectional study assessed oral and dental late effects in MB/CNS-PNET survivors treated before 20 years of age, and with a minimum of 2 years since treatment. Participants went through an oral and radiographic examination. We assessed oral status using the decayed-missing-filled index (DMFT), oral dryness, maximum mouth opening (MMO), fungal infection, and registration of dental developmental disturbances (DDD) in the form of hypodontia, microdontia, and enamel hypoplasia. RESULTS The 46 participants' mean age at enrolment was 27 ± 12.8 years and at treatment 8.5 ± 5.2 years, and the mean time since treatment was 18.9 ± 12 years. Over a third (35%) of survivors had reduced mouth opening (mean 29.3 ± 5.6 mm (range 16-35)). A significantly lower MMO was found in individuals treated ≤ 5 years compared to survivors treated > 5 years (p = 0.021). One or more DDD were registered in 30.4% of the survivors, with a significantly higher prevalence in individuals treated ≤ 5 years (p < 0.001). Hypodontia was the most prevalent type of DDD. There was no difference in DMFT score in relation to age at treatment. Oral dryness was not frequently reported or observed in these survivors. CONCLUSION Survivors of childhood MB/CNS-PNET are at risk of oral and dental late effects including reduced mouth opening and DDD. The risk is highest in survivors treated before the age of 5.

Long-Term Effects of Childhood Cancer Treatment on Dentition and Oral Health: A Dentist Survey Study from the DCCSS LATER 2 Study. Cancers (Basel) 2021; 13:cancers13215264. [PMID: 34771429 PMCID: PMC8582458 DOI: 10.3390/cancers13215264] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Revised: 10/16/2021] [Accepted: 10/16/2021] [Indexed: 11/21/2022] Open
Abstract
Simple Summary We aimed to identify the prevalence of and independent risk factors for dental and oral problems in childhood cancer survivors (CCSs). This cross-sectional study is part of the Dutch Childhood Cancer Survivor Study (DCCSS) LATER 2. Our study included survey data on 154 CCSs, on whom information from dentists on oral health data was received (71.3%). In total, 36.3% of survivors were reported to have at least one dental developmental disorder (DDD). The most prevalent DDDs were short-root anomaly (14.6%), agenesis (14.3%), and microdontia (13.6%). Risk factors for at least one DDD were younger age at diagnosis (<3 years vs. 5+ years) and dose-dependent alkylating agent therapy. This study provides more insight into risk factors for oral health problems in Dutch CCSs. This information is essential in order to improve early detection, prevention, and dental care of oral health problems in CCSs. Abstract Objectives: The aim of this study was to identify the prevalence of and independent risk factors for long-term effects of childhood cancer treatment on the dentition and oral health in childhood cancer survivors (CCSs). Methods: This cross-sectional study is part of the Dutch Childhood Cancer Survivor Study (DCCSS) LATER 2. CCSs were diagnosed with cancer between 1963 and 2001. This study focuses on survey data of 154 CCSs on whom information about their oral health was received from their dentists (71.3%). Descriptive statistics and univariable and multivariable Poisson regression analyses were performed to determine the association between treatment characteristics and oral health data. Results: Of the study group, 36.3% had at least one DDD. The most prevalent DDDs were short-root anomaly (14.6%), agenesis (14.3%), and microdontia (13.6%). Risk factors for at least one DDD were younger age at diagnosis (<3 years) and dose-dependent alkylating agent therapy. Conclusions: This study provides more insight into risk factors for oral health problems in Dutch CCSs. This information is essential in order to improve early detection, prevention, dental care, and quality of life. Further studies are needed in order to better define dose-related radiotherapy exposure of the developing teeth in correlation with oral health problems.

Abstract
BACKGROUND This systematic review summarizes the prevalence of dental defects after chemo and radiation therapy and correlates the findings with specific characteristics of each treatment modality. METHODS Database search was performed for studies reporting dental late effects of chemo and radiation therapy. After data extraction and risk of bias assessment, prevalence of crown and root defects was assessed. Correlations between each defect and the characteristics of the antineoplastic treatment were performed. RESULTS Sixteen nonrandomized studies were included, yielding a total of 1300 patients with a mean age at diagnosis of 4.5 years. Results reported that root defects were more common than crown defects. The most common root defect was impaired root growth and microdontia the most common crown defect. Age, radiation dose and field were statistically associated with higher prevalence of dental defects. CONCLUSION Defects were associated with combination of chemotherapy and radiotherapy, as used in current therapeutic antineoplastic modalities.

Abstract
BACKGROUND Molar incisor hypomineralization (MIH) is an idiopathic syndrome that has been associated with several etiologic factors. The authors' objective was to systematically review studies in which the investigators had studied how the etiology of MIH was related to medication intake. TYPES OF STUDIES REVIEWED The search covered a period from January 1, 1965, to September 29, 2014. The search revealed 1,042 articles, to which the authors applied eligibility criteria and selected 20 studies for review. The authors considered 9 of the 20 studies to be high quality. The drugs used in these studies were chemotherapeutic drugs, antibiotics, asthma drugs, antiepileptic drugs, antiviral drugs, antifungal drugs, and antiparasitic drugs. RESULTS Two reviewers independently performed risk-of-bias assessment and data extraction. The investigators of all of the studies had reported enamel defects, but only 2 sets of investigators had used the term "molar incisor hypomineralization." Owing to the different methodologies used by the investigators of the selected studies, the authors could not perform a meta-analysis of the study results. CONCLUSIONS More well-designed prospective studies are needed to clarify the relationship between MIH and medication. PRACTICAL IMPLICATIONS It would be convenient to establish a preventive protocol in patients with a potential risk of developing MIH to avoid the complications that are characteristic of this disease.

Abstract
Background Survivors of childhood cancer are at risk of late dental development. Cyclophosphamide is one of the most commonly used chemotherapeutic agents against cancer in children. The aim of this study was to investigate the effects of cyclophosphamide on root formation in the molars of growing mice and to assess the morphological changes in these roots using three-dimensional structural images. Methods We treated 16 12-day-old ICR mice with cyclophosphamide (100 mg/kg, i.p.) and 16 control mice with saline. At 16, 20, 24, and 27 days of age, the mandibular left first molars were scanned using soft micro-computed tomography. After scanning, the structural indices were calculated using a three-dimensional image analysis system, and the images were subjected to three-dimensional reconstruction. The length and apical foramen area of all distal roots were assessed. Histological changes in the apical region were then assessed via hematoxylin and eosin staining. Results The mandibular molars of all experimental mice showed evidence of cytotoxic injury, which appeared in the form of anomalous root shapes. Although all roots developed further after cyclophosphamide injection, the three-dimensional structural images showed that the roots in the experimental group tended to develop more slowly and were shorter than those in the control group. At 27 days of age, the mean root length was shorter in the experimental group than in the control group. Conversely, the apical foramen of the roots in the experimental group tended to close faster than that of roots in the control group. In addition, hematoxylin and eosin staining of the distal roots in the experimental group showed increased dentin thickness in the apical region. Conclusion Our results suggest that cyclophosphamide can result in short root lengths and early apical foramen closure, eventually leading to V-shaped or thin roots.

Abstract
Over the past 50 years there has been considerable progress and success in the field of allogeneic hematopoietic stem cell transplant (HSCT) in children. In addition there has been significant improvement in transplant outcomes for both malignant and nonmalignant indications. These improved outcomes have resulted in many long-term survivors who are experiencing substantial long-term morbidities. There are limited data examining the long-term complications of transplant on the various organs. This issue is complicated by the fact that children receive their transplant at different stages of their growth and development (ie, infant, toddler, child, adolescent, and young adult). Each of these developmental stages has different sensitivities to treatment and can result in different sets of complications. We summarize the long-term side effects of allogeneic HSCT in children.

Abstract
BACKGROUND After radiation treatment of head-and-neck cancer, the impairment of patient's quality of life still remains an issue. After completion of the treatment course, a substantial number of patients develop so-called radiation caries. In addition, almost 50% of all cases of infectious osteoradionecrosis (iORN) of the jaws are directly associated with radiation caries. This review addresses our current knowledge on the etiology and pathogenesis of radiation caries including possible preventive strategies. MATERIALS AND METHODS A PubMed search using the terms "radiation caries" ("radiation related caries", "radiation related damage to dentition") and "radiogenic caries" ("postradiation caries", "dental complications and radiotherapy") was performed. The analysis of its content focused on the etiology, the pathogenesis, and the available knowledge on prophylaxis as well as treatment of radiation caries. RESULTS For this review, 60 publications were selected. As main causal factors for radiogenic caries, either indirect impairment, resulting from alterations in the oral environment (e.g., radiation-induced xerostomia) or direct radiation-induced damage in teeth hard tissues are discussed. Radiation caries remains a lifelong threat and, therefore, requires permanent prevention programs. CONCLUSION To enable optimal medical care of the patients during the time course of radiotherapy as well as afterwards, close interdisciplinary cooperation between radiotherapists, oral surgeons, otorhinolaryngologists, and dentists is absolutely essential.

Abstract
Children who survive hematopoietic stem cell transplantation (HSCT) are at risk for an inordinate number of long-term side effects. Late effects can be secondary to the underlying diagnosis for which the transplant is performed, prior treatment of the disease, the transplant preparative regimen, treatment of the complications of transplant, and immunologic interactions between the graft and the host. This article describes the risks and manifestations of the most commonly reported late effects in survivors of pediatric HSCT.

Abstract
UNLABELLED Dental age is largely used in both forensic studies and clinical practice. All over the world, many studies have been made to determine chronological age using dental ages of individuals, but selecting individuals with no chronic or acute sickness as the study group. Cancer is the second most frequent cause of death in children, and acute lymphoblastic leukemia (ALL) is the most common type of cancer in childhood. Most of the children who survived childhood cancer experienced disturbances in dental development due to cancer therapy or to cancer itself. The aim of this study is to assess dental development in children and teenagers who had suffered from childhood leukemia and were submitted to chemotherapy isolated or associated with radiotherapy, by comparing the dental ages with those corresponding features in a healthy control group. Dental development was analyzed using panoramic radiographs of 92 children divided in two groups: 46 children between 5 and 12 years old, treated for ALL at GRAACC-IOP, UNIFESP, and as a control group, 46 healthy children treated for dental reasons at APCD, São Paulo. The dental age of the subjects was estimated using the system of Demirjian et al. [A. Demirjian, H. Goldstein, J.M. Tanner, A new system of dental age assessment, Hum. Biol. 45(2) (1973) 211-227]. A significant difference was found between the chronological and dental age of patients submitted to antineoplasic therapy for ALL, when compared to those of the control group, but there were no significant differences between patients treated with different protocols for ALL. CONCLUSIONS although the study was within a small group of patients, we could clearly conclude that antineoplastic therapy can interfere in the dental maturity of patients treated for childhood cancer by interfering in dental formation and root development.

PURPOSE The purpose of this study was to assess late effects of cytotoxic therapy with hematopoietic stem cell transplantation (HCT) on dental development in survivors of childhood cancer. MATERIALS AND METHODS Forty children who underwent allogeneic HCT for a variety of hematological malignancies were evaluated at a minimum of 2 years after transplantation. We obtained information on oral symptoms, exposed panoramic radiographs (PRG), and performed an oral examination. PRGs were scored for agenesis and root and/or crown abnormalities. The root-crown ratio was calculated, and dental age was assessed using Demirjian' s method. MAIN RESULTS The studied group showed a significantly higher prevalence of tooth agenesis compared to normative data for first and second premolars in both the maxilla and mandible, as well as the second molars in the mandible (all p values <0.001). Children who were <3 years old at the time of cancer treatment had significantly more missing teeth than older children, F(2,37) = 7.58, p < 0.002. Root-crown ratios were lower in the study sample than those from normative data. In addition, the mean dental age was higher (as a result of earlier apical root closure) than the mean chronological age, t(28) = 2.47, p < 0.020. CONCLUSIONS Nearly all children examined had dental development disturbances, including agenesis, short roots, and arrested root development. An oral/dental evaluation and preventative oral supportive care regimens should be part of programs monitoring late effects in long-term survivors of childhood cancer.

Abstract
The aim of this case-control study was to compare the dental health of a group of long-term survivors of childhood cancer with that of age- and gender-matched healthy controls. All children who had been progress- and/or disease-free for at least 5 years were selected. Caries indices for permanent dentition (DMF/T) and primary dentition (dmf/t) were calculated. Past data were collected from medical and dental records and read separately by one of the authors. The mean age of the subjects at the initial diagnosis of the disease was 4.3 +/- 0.3 yr (range 0.5-14 yr). The mean time lapse from the cessation of the therapy to the present dental examination was 5.0 +/- 0.7 yr. The study group had significantly (p < .001) more carious lesions in their primary teeth than the control group. The mean dmf/t value was 5.8 +/- 0.6 in the long-term survivors compared to 3.4 +/- 0.2 in the controls. The difference in DMF/T value of those children was statistically insignificant (p > .05) compared to healthy subjects (2.1 +/- 0.6 and 1.6 +/- 0.2, respectively). There was a significant positive correlation between the presence of head and neck radiotherapy (r = 0.427, p < .05), the number of months the child had been on chemotherapy (r = 0.413, p < .01), the number of fluoride gel treatments (r = .361, p < .05), and dmf/t values, separately. Based on the results of this study, our Unit now considers a through semiannual dental examination for every child who will be or has been treated at Pediatric Oncology Department to be mandatory. The focus should be on caries prevention and include dietary counseling, oral hygiene, and fluoride applications if necessary.

Abstract
OBJECTIVES This study characterized the self-reported dental utilization practice of long-term survivors of childhood cancer, a group at increased risk for treatment-induced dental abnormalities. METHODS 9,434 survivors and a comparison group of 3,858 siblings completed a 289-item survey that included a question on when their last dental visit occurred. RESULTS Within the last year 60.4 percent of survivors reported a dental visit. The groups less likely to report a recent dental visit include minority subjects, subjects with low levels of educational attainment, subjects with annual household incomes < dollar 20,000, and those without health insurance. No significant differences between survivors and siblings were seen. Male survivors exposed to cranial radiation were slightly more likely than other male survivors to report a recent dental visit (OR = 1.27, 95% CI = 1.12, 1.44). CONCLUSIONS The dental utilization practices among survivors of childhood cancer are below recommended levels, even among those at highest risk for dental abnormalities.

Abstract
Severe combined immunodeficiency (SCID) is a rare primary immunodeficiency disorder with an estimated overall frequency of 1 in 75 000 live births. Bone marrow transplantation is the only curative treatment available. Using T cell-depleted HLA non-identical bone marrow requires preconditioning with a short course of cytotoxic chemotherapy. We report severe dental developmental anomalies in three such patients under long-term follow up.

Abstract
The aim of this study was to evaluate, under organ culture conditions, the cytotoxic effects of daunorubicin on tooth development. Three-day-old maxillary hamster second molars were exposed for 24 h in vitro to 108-10-4 M daunorubicin and then evaluated biochemically and histologically. At 10-6 M daunorubicin dose-dependently decreased tooth germ dry weight, cell proliferation ([3H]thymidine uptake), and insoluble [32P] phosphate uptake (phosphorylation of macromolecules). [45Ca]calcium uptake, a marker for mineralization, was significantly affected only at the highest concentration (10-4 M) tested. Histologically, 10-6 M daunorubicin induced necrosis of the proliferating but not the differentiated protein-secreting cells. At 10-4 M, however, all cells were dead. These results indicate that daunorubicin is particularly toxic to the proliferating cells of the tooth germ. Thus, it can be postulated that children treated with daunorubicin may develop defects in the erupted teeth mainly associated with those regions that were in the proliferating stage at the onset of anticancer chemotherapy.

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.
