Çiftçi BT, Aşantoğrol F. Utilization of machine learning models in predicting caries risk groups and oral health-related risk factors in adults. BMC Oral Health 2024; 24:430. [PMID: 38589865 PMCID: PMC11000438 DOI: 10.1186/s12903-024-04210-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Accepted: 03/30/2024] [Indexed: 04/10/2024] Open
Abstract
BACKGROUND The aim of this study was to analyse the risk factors that affect oral health in adults and to evaluate the success of different machine learning algorithms in predicting these risk factors. METHODS This study included 2000 patients aged 18 years and older who were admitted to the Department of Oral and Maxillofacial Radiology, Faculty of Dentistry, Gaziantep University, between September and December 2023. In this study, patients completed a 30-item questionnaire designed to assess the factors that affect the decayed, missing, and filled teeth (DMFT). Clinical and radiological examinations were performed, and DMFT scores were calculated after completion of the questionnaire. The obtained data were randomly divided into a 75% training group and a 25% test group. The preprocessed dataset was analysed using various machine learning algorithms, including naive Bayes, logistic regression, support vector machine, decision tree, random forest and Multilayer Perceptron algorithms. Pearson's correlation test was also conducted to assess the correlation between participants' DMFT scores and oral health risk factors. The performance of each algorithm was evaluated to determine the most appropriate algorithm, and model performance was assessed using accuracy, precision, recall and F1 score on the test dataset. RESULTS A statistically significant difference was found between various factors and DMFT-based risk groups (p < 0.05), including age, sex, body mass index, tooth brushing frequency, socioeconomic status, employment status, education level, marital status, hypertension, diabetes status, renal disease status, consumption of sugary snacks, dry mouth status and screen time. When considering machine learning algorithms for risk group assessments, the Multilayer Perceptron model demonstrated the highest level of success, achieving an accuracy of 95.8%, an F1-score of 96%, and precision and recall rates of 96%. CONCLUSIONS Caries risk assessment using a simple questionnaire can identify individuals at risk of dental caries, determine the key risk factors, provide information to help reduce the risk of dental caries over time and ensure follow-up. In addition, it is extremely important to apply effective preventive treatments and to prevent the general health problems that are caused by the deterioration of oral health. The results of this study show the potential of machine learning algorithms for predicting caries risk groups, and these algorithms are promising for future studies.

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.

Abstract
OBJECTIVES To evaluate the presence of developmental dental anomalies, like microdontia, hypodontia, abnormally shaped teeth (AST), and developmental defects of enamel (DDE) in childhood cancer survivors and compare it with the healthy controls. METHODS This cross-sectional analytical study was conducted in 2 groups: childhood cancer survivors (CCS) group including children (> 12 y, m/f) who had undergone anticancer therapy (ACT) before 8 y of age and healthy control group (> 12 y, m/f) without any systemic disease. Pearson chi-square test was used to analyze the difference between the CCS group and the control group for microdontia, hypodontia, AST, DDE and for intragroup analysis in CCS group. Odds ratio was also calculated. RESULTS A total of 120 and 121 children were included in CCS and control group, respectively. The prevalence of microdontia, hypodontia, abnormally shaped teeth, and DDE was 17.5% (21), 5% (6), 8.33% (10), and 37.5% (45), respectively in CCS group. It was 8.2% (10), 2.5% (3), 1.65% (2), and 22.3% (27), respectively in the control group. A statistically significant difference was seen in microdontia (p = 0.032), abnormally shaped teeth (p = 0.017) and DDE (p = 0.01). Higher prevalence was seen when ACT began at an early age. CONCLUSION An association between developmental dental anomalies and anticancer therapy (ACT) exists with significantly higher difference in microdontia, abnormally shaped teeth and DDE among survivors of childhood cancer as compared to healthy population. These known adverse effects of ACT on developing teeth should be considered during treatment planning of the children having cancers.

Abstract
OBJECTIVES In paediatric cancer survivors treated with chemotherapy and radiotherapy therapy, late effects on dental development are quite common. Oral radiologists are not familiar with the radiographic images of these specific dental consequences of chemotherapy and radiotherapy. With the goal of educating colleagues, to raise awareness of the needs of survivors, and to identify directions for future research, we present dental radiographs of survivors treated for head and neck rhabdomyosarcoma with chemotherapy and radiotherapy. Also, based on the survivors reviewed, a radiographic inventory of commonly found late dental developmental effects seen in conjunction with treatment is presented. METHODS Panoramic radiographic findings of five illustrative cases are presented, from a group of 42 survivors of head and neck rhabdomyosarcoma treated at the Academic Medical Center Amsterdam, The Netherlands over the past 25 years. RESULTS Five cases showing dental developmental disorders are presented. These cases show an association of the location of the radiation field and the developmental stage of the teeth with the severity of the effect on dental development. We also report an inventory of severe and moderate effects of chemotherapy and radiotherapy on the development of molars and anterior teeth. CONCLUSIONS This paper presents five cases and a radiographic inventory to illustrate disturbances of dental development associated with chemotherapy and radiotherapy in children. Medical and dental professionals involved in the treatment of cancer survivors are relatively unaware of the dental consequences of radiation therapy and the age dependency of specific regional effects. These effects can be severe, with great impact on quality of life. Further research in this area could help improve planning of radiation therapy for children, potentially preventing or limiting dental or maxillofacial sequelae.

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
This study was an examination of dental care utilization among survivors of early life cancers (cancer diagnosis at 20 years of age or younger) and the extent to which socio-economic factors may present a barrier to care. Data were obtained from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2016 (n = 28,640). Survey-weighted regression models were used to evaluate associations between early life cancers and subsequent frequency of dental care as adults. A mediation analysis was conducted to test education and household income as potential mediators of this association using a non-parametric bootstrap approach. Early life cancers were associated with a significant decrease in dental care utilization as adults (OR:0.459, 95%CI:(0.226, 0.935)). This diminished utilization was particularly pronounced with survivors in their 20s and 30s. Over time dental care utilization began a slow recovery. The association between early cancer and level of education was estimated to be negative but did not reach statistical significance (OR:0.739, 95%CI:(0.503, 1.086), p = 0.123). Survivors of early life cancers were less likely to be in a higher income bracket (OR:0.663, 95%CI:(0.452, 0.973), p = 0.036)). Decreases in education and household income (p < 0.001) mediated the association between early cancers and lower dental utilization. This pathway accounted for 41.7% (95%CI:(14.1%, 50.6%)) of the association. Survivors of early life cancers did not utilize professional oral health care at a rate commensurate with their risk of dental disease. Providers involved in the long-term care should promote routine dental maintenance. Further study into non-economic barriers in this population is warranted.

Abstract
Aim To study the prevalence of orofacial manifestations in leukemic children undergoing treatment and to correlate these manifestations with various stages of chemotherapy. Materials and methods A prospective noninvasive study comprising 43 acute lymphocytic leukemic pediatric patients at various stages of therapy. They were examined on day of their each blood examination, and lesions were recorded on a self-designed pro forma. A total of 133 observations were recorded by a single observer. The treatment was divided into the phase of induction, consolidation, maintenance, and relapse. Results The data were analyzed using Statistical Package for the Social Sciences (SPSS) version 10.1. There were 24 males and 19 females in this study, aged between 3 and 13 years. The common oral lesions seen were dental caries, lymphadenopathy (86.04%), pallor (65.11%), ulcers (13.95%), mucositis (16.27%), gingival enlargement, hemorrhages (20.93%), candidiasis, herpes simplex virus (HSV) infection, xerostomia (44.18%), paresthesia, and tooth mobility. Herpes simplex virus infection was seen only during induction and consolidation phases. Ulcers were seen during all phases of therapy. Clinical significance Orofacial manifestations may be seen as the first sign of leukemia and a dentist may play a significant role in the diagnosis of the disease per se. This study highlights not only about commonly occurring lesions but also their variation during various phases of therapy. To the best of our knowledge, no study has such an extensive reporting of orofacial manifestations of acute lymphocytic leukemia (ALL) patients under treatment.

Abstract
AIM OF THE STUDY Chemotherapeutic treatment in children and adolescents carries a risk of congenital tooth disorders and dentinoma. Study objective is to assess the correlation between tooth abnormalities, early complications of multidrug chemotherapy, and chemotherapeutics used in different antineoplastic therapies in children and adolescents. MATERIAL AND METHODS Enamel defects (developmental defects of enamel index - DDE index) and defects in tooth number, size, and structure were assessed clinically and radiologically in 60 patients who underwent chemotherapy on average 4.9 ±3.4 years earlier (PCH), and 60 generally healthy subjects (control group - CG), aged 6-18 years. Höltta's defect index (DeI) was calculated. Medical files provided information on neoplasm type, age at treatment start and chemotherapy duration, chemotherapeutic type and dose, vomiting, and mucositis (CTCAE v4.0). Statistical significance of differences between groups was assessed with the Mann-Whitney U test and the correlation between dental defects and chemotherapy with Spearman's rank correlation coefficient (significance p ≤ 0.05). RESULTS Enamel defects, tooth agenesis, microdontia, root resorption, taurodontism, and dentinoma occurred statistically significantly more often in the PCH group. A correlation was established between vincristine use and dose and all types of dental defects; cyclophosphamide, doxorubicin, and isophosphamide and hypodontia; microdontia, root resorption, and enamel defects; etoposide and cisplatin and microdontia, root resorption, and enamel defects; methotrexate root resorption and enamel defects; carboplatin and dentinoma and enamel defects. Mucositis and vomiting promoted root resorption, microdontia, and enamel defects. CONCLUSIONS Dental defects are related to both the use of respective chemotherapeutics, especially vincristine, cyclophosphamide, doxorubicin, and isophosphamide, and to early complications in multidrug chemotherapy - mucositis and vomiting. Vincristine and carboplatin use may promote dentinoma.

Abstract
AIM OF THE STUDY To determine reasons for the increase in caries among children/adolescents treated for neoplasms. MATERIAL AND METHODS Health promoting behaviour, oral hygiene (PLI), gingiva (GI), dentition (DMFt/DMFs), number of teeth with white spot lesions (WSL), and enamel defects (ED) were assessed in three groups of 60 patients each. The three groups were as follows: under chemotherapy (CH), after chemotherapy (PCH), and generally healthy (CG). Medical files supplied information on neoplasm type, chemotherapeutic type and dose, age at treatment start, chemotherapy duration, and complications. Statistical analysis was performed with Mann-Whitney U test and Spearman's rho test. RESULTS The age at which chemotherapy was started/its duration was 5.9 ±4.0/1.3 ±0.5 years in PCH and 9.12 ±4.44/0.8 ±0.3 years in CH; PCH completed treatment 4.9 ±3.4 years ago. Chemotherapy most often included vincristine (VCR), etoposide (VP-16), adriamycin (ADM), cyclophosphamide (CTX), cisplatin (CDDP), and ifosphamide (IF). Mucositis occurrence was 28.33% in PCH and 45.00% in CH; vomiting occurrence was 43.33% and 50.00%, respectively. Nutrition and prophylaxis mistakes occurred more often in CH/PCH than in CG; PLI, GI, caries incidence and severity, and the number of teeth with WSL were higher. Correlation between caries incidence and chemotherapeutic type and dose, age at treatment start and treatment duration, mucositis, emesis, PLI, GI, ED, no fluoride prophylaxis, and nutritional mistakes was established. Ifosphamide and mucositis treatment played a major role in chemotherapy; after chemotherapy - ED and CTX, ADM, IF, and VP-16. CONCLUSIONS Caries in permanent teeth in children/adolescents undergoing chemotherapy result from nutritional mistakes, poor prophylaxis, and indirectly from chemotherapy complications (first mucositis and emesis, and later developmental ED).

Abstract
Cancer is the third most frequent cause of death in children in Brazil. Early diagnosis and medical advances have significantly improved treatment outcomes, which has resulted in higher survival rates and the management of late side effects has become increasingly important in caring for these patients. Dental abnormalities are commonly observed as late effects of antineoplastic therapy in the oral cavity. The incidence and severity of the dental abnormalities depend on the child's age at diagnosis and the type of chemotherapeutic agent used, as well as the irradiation dose and area. The treatment duration and aggressivity should also be considered. Disturbances in dental development are characterized by changes in shape, number and root development. Enamel anomalies, such as discoloration, opacities and hypoplasia are also observed in these patients. When severe, these abnormalities can cause functional and esthetic sequelae that have an impact on the children's and adolescents' quality of life. General dentists and pediatric dentists should understand these dental abnormalities and how to identify them aiming for early diagnosis and appropriate treatment.

Abstract
Survivors of childhood cancer are at risk for dental late effects. This systematic review summarizes associations between treatment exposures and dental late effects among survivors of childhood cancer. We included investigations with at least 20 study participants conducted for 2 or more years after completion of childhood, adolescent, or young adult cancer therapy. This review suggests both independent and additive effects of radiotherapy and chemotherapy on dental complications, and identifies vulnerable groups with specific host and treatment characteristics. This summary provides information that will assist clinicians to prevent, detect, and facilitate early intervention for dental late effects.

Abstract
BACKGROUND The aim of this study was to investigate the long-term effects of chemotherapy on the dental and gingival health and dental disturbance parameters of children cancer survivors. PROCEDURE Thirty-eight children (mean age 12.2 ± 0.5 years) who underwent chemotherapy at 4.29 ± 1.71 years of age formed the study group. Forty age- and gender-matched healthy children with a similar socioeconomic background served as controls. Subjects' caries status (number of decayed, missing, or filled permanent teeth [DMF-T]) was recorded according to World Health Organization criteria. Subjects' periodontal status was recorded according to the community periodontal index system. Radiographic dental examination was used to analyze dental malformations. RESULTS DMF-T, D-T (number of decayed permanent teeth), and F-T (number of filled permanent teeth) were significantly higher in the study group compared to the controls (4.61 ± 3.71, 3.97 ± 4.45, respectively, and 0.58 ± 0.14 vs. 2.21 ± 1.01, 0.84 ± 1.82, and 1.18 ±1.07, respectively. The most frequent dental disturbances were root malformation (52.6%) and agenesis (47.4%). CONCLUSIONS According to our examination dental status of long-term survivors is worse than in controls. Hence proper oral hygiene for children cancer survivors (CCS) is critical. In order to meet the need for dental care in CCS health authorities are encouraged to revitalize the dental services Long-term follow-up of CCS is necessary to monitor their dental growth and oral health.

Abstract
BACKGROUND Adverse long-term general and dental health effects of cancer and cancer therapy during childhood have been reported. AIM To examine the association between chemotherapy before the age of 8 years and (1): microdontia; (2): hypodontia of premolars and permanent molars. MATERIAL AND METHODS In The Danish Registry of Childhood Cancer (DBCR), we identified 203 children who met the following inclusion criteria: (1) age below 8 years at the start of treatment; (2) age between 12 to 18 years upon dental examination; (3) had received chemotherapy The exclusion criterion was radiotherapy to the head and neck. A total of 150 children fulfilled the inclusion criteria. As controls, a random sample of 193 age-matched unexposed children was included. RESULTS Microdontia was found in a total of 88 teeth in 29 (19.3%) of the 150 children who had been exposed to chemotherapy, while none of the controls had microdontia of premolars or permanent molars (difference: 19.3%; 95% CL: 13.5%; 26.4%). The earlier the exposure, the more frequent was microdontia. We found a total of 27 missing premolars and permanent molars in 14 (9.3%) of the exposed children and a total of 18 missing premolars and permanent molars in 8 (4.1%) of the controls (difference: 5.2%; 95% CL: -0.1%; 11.3%). CONCLUSION The present study confirms findings from previous studies that chemotherapy, especially in very young children, causes microdontia and hypodontia of premolars and permanent molars.

Abstract
BACKGROUND The aim of this study was to examine the effect of antineoplastic therapy on dental development and saliva function in recipients of childhood antineoplastic therapy. METHODS Patients attending the long-term follow-up clinic at Children's Hospital at Westmead, NSW, Australia, were included if they had received treatment prior to 16 years of age and were in remission for more than 5 years. A dental examination and saliva test were performed for each participant. Holtta's Defect Index (HDI) was used to assess tooth aplasia, microdontia, and root-crown ratio on an orthopantomogram (OPG). Multivariable-adjusted regression analyses were used to estimate the association of patient characteristics and treatment modalities with dental outcomes. RESULTS One hundred six participants (61% male) were recruited (response rate = 88%). The mean HDI score was 24.7 ± 17.8. A cumulative dose of cyclophosphamide >7500 mg/m(2) increased the HDI score by 13.06 (P = .01). Recipients of cyclophosphamide also had significantly increased odds of exhibiting very low saliva flow (<0.7 mL/min) (odds ratio = 12.43; 95% confidence interval, 2.08-74.35; P = .006). CONCLUSIONS Children and adolescents who received high doses of cyclophosphamide were at increased risk of dental disturbances. Cyclophosphamide recipients were also at greater risk of exhibiting very low saliva flow. This study applied the HDI to patients receiving all forms of antineoplastic treatment and highlights the dose-dependent relation between cumulative dose of cyclophosphamide and dental disturbances.

Abstract
INTRODUCTION This purpose of this systematic review was to evaluate the literature and update our current understanding of the impact of present cancer therapies on the dental apparatus (teeth and periodontium) since the 1989 NIH Development Consensus Conference on the Oral Complications of Cancer Therapies. REVIEW METHOD A systematic literature search was conducted with assistance from a research librarian in the databases MEDLINE/PubMed and EMBASE for articles published between 1 January 1990 and 31 December 2008. Each study was independently assessed by two reviewers. Taking into account predetermined quality measures, a weighted prevalence was calculated for the prevalence of dental caries, severe gingival disease, and dental infection. Data on DMFT/dmft, DMFS/dmfs, plaque, and gingival indexes were also gathered. The level of evidence, recommendation, and guideline (if possible) were given for published preventive and management strategies. RESULTS Sixty-four published papers between 1990 and 2008 were reviewed. The weighted overall prevalence of dental caries was 28.1%. The overall DMFT for patients who were post-antineoplastic therapy was 9.19 (SD, 7.98; n = 457). The overall plaque index for patients who were post-antineoplastic therapy was 1.38 (SD, 0.25; n = 189). The GI for patients who were post-chemotherapy was 1.02 (SD, 0.15; n = 162). The weighted prevalence of dental infections/abscess during chemotherapy was reported in three studies and was 5.8%. CONCLUSIONS Patients who were post-radiotherapy had the highest DMFT. The use of fluoride products and chlorhexidine rinses are beneficial in patients who are post-radiotherapy. There continues to be lack of clinical studies on the extent and severity of dental disease that are associated with infectious complications during cancer therapy.

Systemic disorders and their influence on the development of dental hard tissues: a literature review. J Dent 2010; 38:296-306.

Abstract
OBJECTIVES This report highlights the influence of a number of disorders with systemic physiological effects that impact on the development of dental hard tissues. It focuses in particular, on the pathological effects of systemic conditions with less well recognised, but no less important, impacts on dental development. Such conditions, include cystic fibrosis, HIV/AIDS, leukaemia, Alstrom syndrome, hypophosphatasia, Prader-Willi syndrome, Tricho-dento-osseous syndrome, tuberous sclerosis, familial steroid dehydrogenase deficiency and epidermolysis bullosa. These, along with developmental and environmental causes of enamel and dentine defects, are discussed and the possible aetiology of such effects are proposed. Furthermore, the dental management and long-term dental care of these patients is outlined. SOURCES MEDLINE/PubMed. CONCLUSIONS Enamel and dentine defects can present with a wide spectrum of clinical features and may be caused by a variety of factors occurring throughout tooth development from before birth to adulthood. These may include host traits, genetic factors, immunological responses to cariogenic bacteria, saliva composition, environmental and behavioural factors and systemic diseases. These diseases and their spectrum of clinical manifestations on the organs affected (including the dentition) require an increased knowledge by dental practitioners of the disease processes, aetiology, relevant treatment strategies and prognosis, and must encompass more than simply the management of the dental requirements of the patient. It is important that the impact of the disease and its treatment, particularly in respect of immunosuppression where dental interventions may become life-threatening, is also taken into consideration.

Abstract
BACKGROUND With increasing survival rates for childhood cancer, late effects are of growing importance. Oral health is central to general health, level of nutrition, quality of life, and is significant in the holistic care of children during cancer therapy. HYPOTHESIS The oral health needs of children treated for solid tumours/lymphoma will be greater than the general population, groups will differ according to tumour and treatment. DESIGN One hundred and twenty patients, 0-17 years, under follow-up from 01/07/06 to 07/02/07 were investigated for caries, opacities, microdontia, and gingivitis. Analysis was performed with stratification according to tumour and treatment. Comparisons made with the UK 2003 Child Dental Health Survey. RESULTS The neuroblastoma group and high-dose chemotherapy with stem-cell rescue (HDCSCR) therapy group had increased caries of the primary teeth. Chi-squared analysis revealed a statistically significant relationship (P < 0.03) between the age at receipt of chemotherapy (<3.5 years) and the presence of microdont teeth. CONCLUSION Oral health care is important for all patients particularly those with a neuroblastoma, or who received HDCSCR. Patients should be advised about the possibility of microdontia in the permanent dentition following chemotherapy under 3.5 years.

Abstract
BACKGROUND This study was conducted to evaluate oral health and dental anomalies in children treated for acute lymphoblastic leukemia (ALL) and to compare results with those of a group of healthy children matched for sex and age. PROCEDURE Fifty-six children treated for ALL and 56 healthy controls were examined for dental anomalies, and data on decayed, missing, and filled teeth (DMFT) score, visible plaque (VPI), and gingival bleeding (GBI) indices, and saliva flow were collected. Mean age of all children treated for ALL was 5.3 +/- 2.6 years at diagnosis and 11.8 +/- 4.2 at evaluation. Thirty-two were males. RESULTS Forty-five treated children (80.4%) had at least one dental anomaly, and patients treated with chemotherapy, radiotherapy, and bone marrow transplantation had the greatest mean number of dental anomalies (15.37 +/- 15.03). Patients younger than 5 years at beginning of treatment were also more affected (P = 0.031). Children treated for ALL had a DMFT score of 1.9 +/- 4.0, GBI of 26.5%, VPI of 72.0%, and mean saliva flow of 0.19 ml/min; healthy children had a DMFT score of 1.52 +/- 3.5, GBI of 11.1%, VPI of 53.8%, and mean saliva flow of 0.27 ml/min. CONCLUSION The treatment of ALL causes a significant increase in the number of dental anomalies. Their GBI and VPI were also elevated. Changes in salivary glands during treatment did not affect saliva flow permanently. Follow-up of these patients by an oral health team is recommended.

Abstract
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
BACKGROUND The few published studies on caries among childhood cancer survivors are small and their results are conflicting. The study aim was to examine the risk of dental caries among children who have survived cancer. PROCEDURE We included 299,426 7-year-old, 313,461 12-year-old, and 301,930 15-year-old children born between 1984 and 1988 in a nationwide population-based study linking records from Danish Cancer Registry with records from the national database on oral health. Children whose dental examinations had been preceded by a cancer diagnosis (288 7-year-old, 459 12-year-old, and 526 15-year-old) were compared with children without cancer according to presence of caries: caries-free children; children with any caries experience; and children with severe caries experience (i.e., caries in one or more smooth tooth surface). RESULTS Children diagnosed with cancer before the age of 5 years did not have increased caries prevalence in permanent teeth at ages 12; and 15. Children diagnosed with cancer between 5 and 6 years of age had an increased prevalence of severe caries at age 12 years (prevalence ratio (PR) = 1.59 (95% CI: 1.09-2.31; P = 0.02)), but this difference disappeared by age 15. For children diagnosed with cancer at 5 or 6 years of age and who received radiation therapy the PR of severe caries was 1.52 (95% CI: 0.97-2.37; P = 0.07), 2.13 (95% CI: 0.89-5.10; P = 0.09), and 0.31 (95% CI: 0.07-1.45; P = 0.13) at ages seven, 12 and 15 years respectively. CONCLUSION Cancer and cancer treatment during childhood are risk factors for caries.

Abstract
OBJECTIVE The aim of this study was to investigate the long-term effects of chemotherapy on oral health and dental development in childhood cancer survivors (CCS). STUDY DESIGN Ninety-six CCS patients with a mean age of 10.8 years and 96 healthy children of the same age and sex and social background composed the study group. The caries experience of the children was recorded according to the criteria of the World Health Organization, and plaque-gingival status was evaluated according to the Silness-Loe Index. The children were also investigated for stimulated salivary flow rate, buffer capacity, salivary mutans streptococci, and lactobacilli. Disturbances of enamel mineralization were recorded according to the index of developmental defects in dental enamel. Dental development disturbances were diagnosed on panoramic radiographs. RESULTS The caries experience, mutans streptococci, and lactobacilli colonization in CCS children were found significantly higher than in the healthy subjects (P < .05). White/cream colored opacities were the most frequent enamel mineralization disturbances (69.8 %). The occurrence of arrested root development with short V-shaped root malformation was significantly higher in CCS children than in the healthy subjects (P < .05). No statistically significant difference was found between group <or=5 years and >5 years. CONCLUSION This current investigation has shown that CCS children are at an increased risk of caries and developmental dental disturbances.

Abstract
Dental abnormalities among children treated at a young age for Wilms tumor are reported. The authors retrospectively reviewed the dental records and panoramic radiographs of 27 children treated for nephroblastoma between 1994 and 1998. They evaluated the frequency of apparent microdontia, excessive caries, root stunting, hypodontia, and enamel hypoplasia and compared this group to a control group of 78 children. Seventy percent of the children developed dental abnormalities, comprising root stunting (44%), enamel hypoplasia (22%), microdontia (18%), and hypodontia (7%). Results of control subjects were significantly different regarding dental abnormalities, especially microdontia and taurodontia. These results indicate that chemotherapy in children may lead to troubles affecting teeth growing at the time of treatment. Information and prospective dental care are needed, and further investigations are required.

It is essential that every health care professional who is involved with the prescription or recommendation of drugs be fully aware of any resultant disorders that may arise as a side-effect. A range of drugs can affect the teeth. In this review article, drugs that have the potential to induce changes in teeth have been classified as those leading to tooth discoloration (intrinsic and extrinsic), physical damage to tooth structure (enamel, dentin, and cementum), and alteration in tooth sensitivity.

Abstract
This article aims to raise awareness among paediatricians and specialist paediatric services that poor oral health, in particular children with chronic illness, is a major cause of morbidity and can be a risk factor for severe, even life threatening complications. Good oral health and dentition is important for efficient mastication, speaking and of course, cosmetically for smiling. If left untreated, dental caries can lead to pain and infection. Chronic infection around one or more teeth can result in damage to localised structures, such as the developing permanent teeth. Children who are medically compromised (such as being immunocompromised from disease and/or therapy) however are at increased risk of developing systemic complications from dental infections, which may prove fatal. We focus on the role of the general paediatrician in promoting the importance of good dental health for all children and in particular those children "at risk". We present preventive measures, evidence based where available, that may improve dental care and promote the role of paediatric dental services in the multidisciplinary management of chronic disease.

Abstract
BACKGROUND Deficient dental root development has been reported after conventional pediatric anticancer therapy, but less information is available on stem cell transplantation (SCT) recipients. METHODS Root-crown (R/C) ratios of fully developed permanent teeth were assessed from panoramic radiographs of 52 SCT recipients, who were treated when they were age < 10 years. Using standard deviation scores (SDSs), the authors compared the R/C ratios to the corresponding tooth and gender-specific values in a healthy population. The percentage of affected R/C ratios per individual was examined in a subgroup of 39 (SG39) patients with advanced tooth development. The effects of total body irradiation (TBI) and SCT age on the R/C ratios were studied in TBI and high-dose chemotherapy (HDC = non-TBI) groups and in 3 age groups (< or = 3.0 years, 3.1-5.0 years, > or = 5.1 years). RESULTS Per individual, 77% of the fully developed permanent teeth were affected in SG39. At the tooth level, in 77% of the 945 teeth studied (52 patients), the R/C ratios were outside +/-2 SDSs. More teeth were affected in the TBI (85%) than in the non-TBI (55%) group (P < 0.001). The teeth of the patients who were ages 3.1-5.0 years old at SCT presented with the most severe aberrations of the R/C ratio (mean SDS = -4.4) whereas the teeth of the youngest (age < or = 3.0 years) and the oldest (age > or = 5.1 years) patients were equally affected (mean SDSs = -3.1 and -3.0, respectively). CONCLUSIONS Disturbances of dental root growth always followed pediatric SCT. HDC alone intensely harmed root growth but TBI further increased the adverse effects that were most extensive in the patients 3.1-5.0 years at SCT. These sequelae should be taken into account during the lifelong dental follow-up to minimize the clinical consequences of dental injuries.

Abstract
The aim of this study was to investigate the late effects of treatment for childhood non-Hodgkin's lymphomas (NHL) on oral health and dental development. Thirty-six long-term survivors that had been treated with chemotherapy of childhood NHL were included in this study and 36 volunteers with similar age and sex distribution served as controls. Both groups underwent a complete orodental examination for decayed, missing and filled teeth and surfaces, gingival and periodontal health according to the Loe-Silness Gingival Index and Sillnes-Loe Plaque Index, enamel defects and discolorations, root malformations, eruption status, agenesis, premature apexifications and microdontia. The severity of these disturbances related to age at the time of NHL diagnosis were also evaluated by creating two groups as < 5 yr and > 5 yr. Although none of the parameters altered with age, patients had significantly higher plaque index, more enamel discolorations and root malformations than did the controls. The results show that long-term survivors of NHL patients exhibit some orodental disturbances that may be attributed to the chemotherapy regimens.

Abstract
PURPOSE To describe potential effects of multimodality therapy on dental and facial development in long-term survivors of head and neck rhabdomyosarcoma. PATIENTS AND METHODS The medical records of all patients aged 20 years or less presenting between 1985 and 1996 with a diagnosis of rhabdomyosarcoma and treated by protocol were reviewed. Head and neck rhabdomyosarcoma patients who were followed in the Dental Service and were alive and free of disease with at least a 5-year follow-up were included in the review. Ten patients satisfied the inclusion criteria and form the basis of this report. The median age at diagnosis of the 10 patients was 4.3 years (range 10 months to 19.5 years). All patients were treated with chemotherapy, two patients underwent surgery, and all but one patient received external beam radiation therapy. RESULTS Clinical or radiographic dentofacial abnormalities were observed in 8 of the 10 (80%) patients. Abnormalities included enamel defects, bony hypoplasia/facial asymmetry, trismus, velopharyngeal incompetency, tooth/root agenesis, and disturbance in root development. Bony hypoplasia and disturbance in root formation were the most common findings. CONCLUSIONS Multimodality therapy for head and neck rhabdomyosarcoma can result in dentofacial abnormalities that affect the patient's quality of life. The care of the long-term survivor requires a multidisciplinary approach, including early involvement of the dental team.

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
OBJECTIVE To study the effect of cyclophosphamide (Cy) on bone formation in the maxillary median suture of young rats. STUDY DESIGN Doses of 30 mg/kg body weight of Cy were administered to 12 experimental rats at 10 and 13 days of age. A corresponding amount of 0.9% sodium chloride was given to 6 control rats at the same ages. At 31 days, the median maxillary suture was studied histologically in the experimental and control rats. RESULTS Structural changes of the osteogenic layers and cartilage components of the suture could be seen in the experimental rats. The thickness of the palatal bone was only 66% of that of the control rats, and the experimental rats also exhibited significantly reduced width of the suture. CONCLUSION This study shows that Cy by itself can cause disturbances in bone formation in rats.

Abstract
There have been a number of reports on the dental health of long-term survivors (LTS) of childhood malignancy as compared with normal controls. However, it is usually difficult to identify a meaningful control population as most of these patients are from widely differing geographical areas and socio-economic status. The aim of this investigation was, therefore, to study the dental health of LTS compared with siblings. 46 LTS who had siblings of a similar age were identified for the study. Both groups were examined for dental caries, gingivitis and enamel defects. There was no statistically significant difference in the mean DMFS of the test and control groups. However, the LTS had a significantly (P = 0.006) higher number of decayed surfaces (1.50 +/- 0.30) as compared with their siblings (0.50 +/- 0.20). The LTS also had a significantly higher prevalence of severe gingivitis (1.11 +/- 0.33) compared with controls (0.02 +/- 0.02). There was a significantly higher prevalence of all types of enamel defects in the LTS and fewer teeth with no enamel defect as compared with their siblings, with the mean values being 15.7 +/- 0.9 and 25.3 +/- 0.3, respectively. It was concluded that there was a higher prevalence of untreated dental disease and developmental defects in long-term survivors.

Abstract
Orofacial complications are common after radiotherapy to the head and neck, and after chemotherapy for malignant disease. Mucositis is the most frequent and often most distressing complication, but adverse reactions can affect all other orofacial tissues. This paper discusses the aetiopathogenesis and current means available for preventing, ameliorating and treating these complications, as well as indicating research directions.

Abstract
Cancer treatments often induce oral complications. In this study we investigate longitudinally the salivary gland function, the salivary caries-related microorganisms, and buffer capacity in bone marrow recipients. Stimulated saliva samples were taken midmorning. The salivary factors were studied in 42 patients from before transplant until 4 months after transplant. A dramatic reduction (66%) of salivary flow rate is noticed in all patients at 1 month after transplant, and only a partial recovery (42% reduction) is seen after 4 months. A clear shift toward a lower buffer capacity and a higher amount of cariogenic microorganisms is seen posttransplant. This shift is more pronounced when total body irradiation was included in the pretransplant conditioning therapy. These findings indicate that the studied parameters in transplant recipients can contribute to a higher caries risk and oral complications during the early posttransplant period.

Abstract
Sixty-eight children who were diagnosed with acute lymphoblastic leukaemia (ALL) prior to age 5 years and treated with chemotherapy alone, chemotherapy plus 1800 cGy cranial irradiation (RT), or chemotherapy plus 2400 cGy RT were assessed clinically for overall dental health. All patients were at least 60 months in continuous remission. Dental caries were assessed by NIDR diagnostic criteria, oral hygiene was assessed by the modified Oral Hygiene Index, and gingival health was assessed by the modified gingival index of Loe and Silness. There was no significant difference in caries experience between the three groups nor with the normal population. Those patients that received 2400 cGy RT had significantly higher plaque and periodontal index scores than patients in the other treatment groups. The results of this study suggest that: (1) children with ALL treated with any of the described modalities are at no greater risk of developing dental caries than the normal population; and (2) patients receiving 2400 cGy prior to age 5 years are at greater risk of developing periodontal disease than patients treated with other central nervous system prophylaxis regimens examined in this study.

Abstract
The relation of the therapy used and age at diagnosis to developmental defects of dental enamel and root was analyzed in 45 survivors of childhood acute lymphoblastic leukemia (ALL) and compared to that of age- and sex-matched healthy controls. Chemotherapy alone increased the number of enamel defects, but it did not affect the roots. The scattered irradiation of 0.72-1.44 Gy to the dental arches during central nervous system (CNS) irradiation caused an increased number of developmental defects both in enamel and root. Age at diagnosis is an important factor and it showed that the irradiation of 10 Gy did not cause enamel defects if amelogenesis was complete. In conclusion, the therapy is related to developmental defects of the teeth but the most important factor is age, both at diagnosis and during the therapy.

Abstract
Fifty two children who had had cancer and been treated with chemotherapy, and who were long term event free, were examined for caries prevalence, gingival health, and oral hygiene and compared with a control group. A higher dental caries prevalence for the 14-17 year age group was noted. The restorative index was significantly lower in the age group 10-13. There were no significant differences in gingival index, plaque index, or toothbrushing frequency. It is concluded that these patients should be considered as at high risk for caries after cancer treatment. Professional dental follow up should be integrated in the medical follow up.

Abstract
Disturbances in dental development were studied with the use of radiography and histology in a patient with acute lymphoblastic leukemia who was treated with induction chemotherapy at 2.3 years of age and bone marrow transplantation at 4.3 years of age. The follow-up 9.5 years after bone marrow transplantation showed evidence of short tapered roots, enamel hypoplasia, microdontia, and aplasia. A histologic examination of two extracted permanent teeth showed that the crown of the maxillary lateral incisor exhibited numerous incremental lines that corresponded closely to the treatment periods with cytotoxic drugs. The maxillary second premolar exhibited regularly spaced incremental lines in the enamel and dentine. A gross hypoplasia was seen in the cervical part of the crown corresponding to the time of administration of 10 Gy total body irradiation. The results indicate that chemotherapy mainly induces qualitative disturbances in dentine and enamel, whereas total body irradiation induces both qualitative and quantitative changes.
