Twelve patients were followed for 5 years after treatment with a 12-unit cantilever fixed partial denture on the mandibular canines opposed by a complete maxillary denture. Two fixed dentures had to be removed, one because of an abutment tooth root-fracture and one because of rapid marginal bone loss in a terminal stage of leukemia. Caries and periodontal lesions were rare, but other complications, principally related to endodontics, occurred. All complications were amenable to standard treatment procedures. Extensive mandibular cantilever fixed partial dentures may be used in the rehabilitation of patients with a very reduced dentition and a history of difficulties in adapting to removable dentures.

Fifty-two long-term survivors of childhood leukemia or solid tumors had a clinical dental examination along with 49 of their sibling. The 52, with an additional 30 examined in a previous study, were studied radiologically with a panoramic tomogram. All children with leukemia had received chemotherapy for 2 or 3 years and irradiation on standard protocols and the solid tumor group had received chemotherapy for 6 to 24 months. There was no difference between siblings and patients for dental caries, gingivitis, and oral hygiene, mouth opening, overjet, and overbite. More solid-tumor patients had abnormal occlusion (P less than 0.02) and those with abnormalities tended to have been treated at an earlier age. Enamel opacities and hypoplasia were more common in patients than siblings and in the leukemia than in the solid tumor group. Sixty-five percent of the children had abnormalities on radiologic examination including failure of the tooth to develop, small crown, hypoplasia of the crown, and abnormal root development. In most cases the radiologic abnormality could be correlated in time with the patient's treatment and a knowledge of the normal time of tooth development. Three teeth extracted during the course of the study were examined histologically and these showed prominent incremental lines which could be correlated in time with vincristine treatment.

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.

Dental caries is an infectious disease and it may be harmful for children suffering from leukemia. DMFS, DMFT scores of forty-five children with acute lymphoblastic leukemia (ALL) were significantly higher than in healthy age-and-sex-matched controls after cessation of therapy. The children with CNS irradiation had higher DMFT (7.13 than children with only chemotherapy (3.4) and the controls (1.8). Lifelong caries incidence showed that children with ALL had 2.7 new caries lesions per year during the therapy compared to the 1.1 (p < 0.05) new lesions in controls. More detailed analysis of permanent anterior teeth at the age of twelve years showed that all patient groups had more filled anterior teeth than controls (p < 0.001); and children with bone marrow transplantation had significantly more fillings than the other two groups.

Minimal data about oral and dental health in long-term survivors after BMT are available. We studied the dental status of 27 children (19 males, eight females) with leukaemia, followed up with a routine oral examination, panoramic tomogram and, when necessary, an endoral radiograph at a median of 2 years (range 1-10) after BMT. Community periodontal index treatment necessity (CPITN), dental caries, missing or filled permanent teeth (DMFT) and dento-facial alterations according to WHO criteria were registered and evaluated. Median age of the patients at BMT was 9 years (range 1.1-17.9). The mean DMFT score ranged from 1.6 to 12.4 according to age at examination and was slightly higher than that which we previously reported in children who received chemotherapy alone. CPITN showed the presence of soft deposits in 77.7%, serious gingivitis in 59.2% and parodontal involvement in 3.7% of cases. Dento-facial abnormalities were found in 55.5% of patients, while 62.9% of the patients had tooth abnormalities or agenesis. Nine out of 27 patients (33%) had root hypoplasia. A negative impact on DMFT index due to multiple post-BMT factors was found. Age is the crucial factor in determining a developmental defect of enamel and root. The follow-up of long-term survivors after BMT should include regular dental examination.

The dental condition of 54 children aged 3-19 years who were in remission from acute lymphoblastic leukaemia was examined in relation to the duration of their chemotherapy and their period of time in remission. There were no significant differences in the number of early ('white spot') lesions or in the total dental caries experience in relation to the duration of chemotherapy. Children who were longest in remission had significantly more white spot lesions in permanent teeth but not in primary teeth, and there was no significant difference in dental caries experience. Children who had received nystatin treatment for more than a year had significantly more white spot lesions in permanent teeth than those who had received nystatin for shorter periods.

In this study, oral findings from children suffering from leukemia or other cancers, and hospitalized for treatments, are compared with findings from hospitalized patients from the Children s Surgery Department, without systemic or general illnesses. The aim of the study is to determine possible differences in the status of oral health between the hospitalized cancer-ward children and children hospitalized, but with good general health, in order to develop special prophylactic measures as required. The visual oral findings included the prevalence of caries (DMF/T, Decayed, Missed, Filled/Tooth), oral hygiene, severe periodontal diseases, records of defects of the oral mucosa, and information was collected on fluoridation. For both groups of children, the degree of treatment-need of the remaining dentition was 63%. Caries-free dentition was found in 53.7% of the surgery patients and 40.7% of the cancer-ward children. Good oral hygiene was found in only 49% of the cases among the cancer-ward children, while among the children without systemic illness the figure climbed to 87% of the cases. Gingivitis among the children without general illness was only diagnosed in 7.4% of the cases, but in contrast, among the cancer-ward children the percentage of gingivitis (62.8% ) was significantly higher (p < 0.0001). The present study strongly suggests that for children with cancer and subject to aggressive therapy and/or long hospitalizations, beyond the general medical examination on hospital admission, a dental examination should also be instituted.

Leukemia constitutes approximately 30% of all childhood cancers and Acute Lymphoblastic Leukemia (ALL) is the most common type of malignancy. Oral dryness, ulceration, increased dental decay seen is due to altered salivary flow rate and buffering capacity in these children. Oxidative stress may play an important role in the malignancies resulting in onset of inflammatory oral pathologies. Saliva constitutes first line of defense against free radical-mediated oxidative stress. The present study attempted to relate the oral health status, salivary flow rate, salivary pH, gingival health status, dental caries experience and total salivary antioxidant levels in ALL children. A total of 120 children aged 4-10 years (90 leukemic children, study group and 30 normal healthy siblings, control group) were divided into 4 groups of 30 each. Oral health status, gingival status and dental caries experience was recorded followed by un-stimulated saliva collection. Total antioxidant capacity of un-stimulated saliva was evaluated. The results depicted deterioration in oral health status, gingival status and increased dental caries experience in leukemic children. Salivary flow rate, salivary pH and total salivary antioxidant levels were lowered in leukemic children when compared with control group.

Leukemia is one of the most common malignancies affecting children in India. These children usually suffer from various oral complications, which may be due to the leukemia or due to the chemotherapeutic agents and/or radiotherapy. The complications may include some of the opportunistic infections like candidiasis, herpes simplex; hemorrhage, mucositis, taste alterations and increased incidence of dental caries etc. These complications can cause significant morbidity and mortality in the patients. The aim of this review is to summarize the various oral complications in these children and the methods of prevention and management.

Breastfeeding is the nourishment designed by nature for the newborn and the infant; however its prevalence is nowadays not optimal. The aim of this article is to review the current evidence of the benefits of breastfeeding for children and society, and to elaborate the risks associated with the replacement of lactation with baby formulas. Breastfeeding is a protective factor for several infectious, atopic, and cardiovascular diseases as well as for leukaemia, necrotising enterocolitis, celiac disease, and inflammatory bowel disease. It also has a positive impact on neurodevelopment, improving IQ and reducing the risk of attention deficit disorder, and generalised developmental and behavioural disorders. Lactation can decrease the risk of sudden infant deaths syndrome by 36% and prevent 13% of infant mortality worldwide. Breastfeeding result in direct saving on the use of infant formulas and bottles, and indirectly on associated health costs, premature deaths, and quality-adjusted life years, among others. In addition, breastfeeding is environmentally friendly; it does not leave an ecological footprint in its production and consumption. The use of baby formulas and bottles have inherent risks, because they increase the risk of oral diseases, such as mouth breathing, malocclusion, alteration of bite, and tooth decay. Finally, the intestinal microbiota, oxygenation, and thermoregulation of infants are negatively affected by their use.
