Dental caries, gingival health, and oral hygiene of long term survivors of paediatric malignant diseases.

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.

[Dental care in patients undergoing radiotherapy of the head and neck].

Radiotherapy involving the oral cavity and salivary glands induces a wide range of alterations in oral tissues and salivary gland functions which may result in oral side effects. Some of these are inevitable and transient such as radiation mucositis, some however may be permanent such as xerostomia. Others however are preventable, and are caused by poor radiation techniques, application of excessive radiation doses or lack of necessary preventive measures. Frequent complications in these patients are development of caries, dental hypersensitivity, rapidly progressive periodontal disease and loss of taste. Occasionally, trismus and osteoradionecrosis may develop. Careful treatment planning before start of radiotherapy with adequate dosimetry and careful shielding of the healthy tissues as well as close monitoring of the oral cavity with strict application of preventive measures (dental care protocol) can significantly reduce the incidence of these complications. The private practitioner should keep in mind the life-long precautions that are necessary when treating these patients.

[Mucous lesions associated with hematologic diseases].

Mucosal lesions are a frequent finding in patients with hematologic malignancies. Early diagnosis and institution of adequate therapeutic modalities can significantly reduce the morbidity and even mortality in these patients. Primary lesions are the consequence of infiltration of the oral tissues by malignant cells. Secondary lesions result from the condition of bone marrow suppression induced by replacement of the blood forming tissue by malignant cells. Lesions caused by the oncologic treatment, directly or indirectly, are called tertiary lesions. This article describes and illustrates the different types of lesions.

[The medical history through a list of medical risks. Practical use in dental medicine].

A medical risk related patient-administered history (MRRH) was developed for use in routine dental treatment with or without local anesthesia by the general dental practitioner. The fixed guidelines of the ASA classification may be under discussion. Of course, there are other divisions and combinations conceivable and deviation of the standards may be inevitable. However, the present proposal is to be used for investigation purposes, which makes fixed guide-lines imperative. This MRRH, tested in Belgium, proved to be valid in comparison with the "gold standard", a verbal history taken by a physician experienced in pre-assessment control. The most reliable results can be obtained by a combination of the medical questionnaire and the additional verbal history.

[Oral hygiene of handicapped subjects in Flanders].

As part of an epidemiology survey within the population of handicapped 12-year old in Flanders this article describes several parameters related to oral health. On the average, it became obvious that oral hygiene had to be seriously increased. The presence of plaque and calculus is very typical for types 1, 2, 4 and 8. In addition, it is most striking to conclude that groups where a maximum of self-handiness is expected, do not score any better. The application of chemical controlling agents and the use of fluoride supplements is found extremely low. Finally, a lack was found, with respect to adequate oral hygiene instructions. There is a real need for in-service training programs for educators as well as for parents.

[Down syndrome: 1. Medical aspects].

Each organ of a patient with the Down's Syndrome (trisomy 21) shows the pathology. One notices the specific features already with an infant. The life expectation of these children has increased considerably and it depends upon the appearance or not of a heart defect. The ventricular septum defect is most frequent but a small number of these patients show a complex cardiopathy. The incidence of pulmonary hypertension is also high. The obstruction of gastroenteric tract can cause problems from the prenatal phase onwards. The main endocrinological difficulties are dysfunction of the thyroid gland and also infertility. Ocular disorders like refraction disorders occur frequently. Due to decreased conduction, there is a hearing loss. The cellular immunity is clearly reduced, hence, the susceptibility to infections like hepatitis B, increases. The major oral problems are apparently oversized tongue and a high sensitivity to gingivitis.

[Status of the teeth and degree of care in handicapped in Flanders].

In general, handicapped 12-year old do not show statistical relevant differences with non-handicapped age-matched children in Flanders regarding general caries prevalence, caries distribution and total caries experience. However, important differences were found for the restorative index showing a higher caries treatment need in handicapped children. When the results were analysed according to the type of handicapping condition, it was seen that children with borderline and mild mental handicap and children with speech-, language and/or learning difficulties show the most unfavorable picture. They have a high caries prevalence and caries experience and a low restorative index. Additional analysis of the results can throw some light on the presence of additional caries risk indicators and contributing caries risk factors.

Influence of anticoagulation on blood loss following dental extractions.

The coagulation activity level at which oral surgery procedures can be performed in anticoagulated patients without triggering bleeding complications and without enhancing the risk of developing thrombo-embolic events remains controversial. The objective of the present study was to evaluate blood loss following dental extractions at different levels of anticoagulation and to determine its effect on wound closure rates. Blood loss was measured following the removal of four front teeth in warfarinized rabbits. Immediate blood loss was evaluated by determining the tooth socket bleeding times and by using a technique based on hemoglobin determinations. Long-term blood loss was assessed by comparison of labeled red-blood-cell disappearance curves. The results showed that blood loss following dental extractions was significantly greater in animals anticoagulated at a therapeutic level than in non-anticoagulated control animals. Determination of blood loss at different levels of anticoagulation clearly demonstrated that complete correction of the coagulation activity was unnecessary. Partial correction (INR values of 1.6-1.8) allowed extractions to be performed without extensive blood loss. With this technique of partial correction, the period of interruption of the anticoagulation could be kept very short, and the risk of postoperative bleeding complications was minimal. Wound closure rates were negatively influenced in anticoagulated animals.

[Oral problems and approach to dental care in case of diabetes mellitus].

Diabetic patients often present oral symptoms and complaints at the moment of diagnosis of their disease. Recurrence of these symptoms is possible in periods of poor metabolic control. Long term complications of the disease are noticed at the level of the oral cavity. Dentists can contribute to early recognition of oral manifestations. A careful dental follow-up of these patients is essential in order to reduce the incidence and severity of long term oral complications (advanced periodontal disease, ...) This article reviews the general and oral implications of diabetes mellitus and discusses the results of a clinical study regarding the orodental condition and oral preventive behaviour of children with diabetes. Practical guidelines for the dental care of patients with diabetes are outlined.

[Dental status and dental preventive behavior in Flanders].

Socio-economic factors are important parameters for dental health status and preventive behavior. In an epidemiologic survey of +/- 8000 5- and 12-year old schoolchildren in Flanders significant differences in dental attendance, brushing habits and caries prevalence were found between 12-year old boys and girls. Ethnic differences were pronounced. Dental attendance and brushing frequency were lower in non-West-European children. These children showed a higher caries attack rate at the age of 5 but in 12-year olds the opposite was noted. Interprovincial differences should probably be attributed to differences in social levels.

[Dental care for patients being treated with oral anticoagulants. Prevention of hemorrhagic complications].

The oral management of patients receiving oral anticoagulants is controversial, especially concerning oral surgical procedures. The clinician has to balance the risk of reducing or stopping the medication with that of triggering bleeding complications. For each individual patient and for each dental intervention, two important factors should be evaluated and balanced: the risk for bleeding complications represented by the dental intervention and the medical risk for the patient in case of interruption of the anticoagulant therapy. Practical instructions for the different types of dental interventions and medical risk categories are proposed.

[Oral manifestations in leukemic children and their diagnostic value].

Leukemia is the most common form of cancer in childhood. The disease is characterized by a high incidence of oral complications at diagnosis and during subsequent treatment. Oral complications can be divided in three groups. Primary lesions are induced by the infiltration of the oral structures by malignant cells: gingival infiltration and infiltration of bony oral structures. Secondary lesions are the result of the myelophthisic character of the disease. This group contains symptoms of anemia, increased bleeding tendency and increased susceptibility to infections. Tertiary lesions are induced by the antileukemic treatment patients receive. Direct and indirect cytotoxic effects can be distinguished. This article reviews the different oral manifestations, describes the most prominent characteristics of the different oral symptoms and demonstrates the importance of early and correct recognition of these symptoms for the oncologist. This can be important for diagnosis of the disease, but also for prevention and treatment of complications during the subsequent treatment. Dentists and stomatologists can contribute to a better prognosis and a reduction of morbidity and mortality of this disease.

[Intrusion of the definitive incisors].

Intrusive luxations make up about 5% of the dental traumata on permanent front teeth. Clinical and radiological findings are described. Practical guidelines are given for the treatment of intruded teeth, with or without completed root formation, based on literature findings and clinical experience. Much attention is given to the question whether one should prefer orthodontic extrusion or choose for surgical reposition followed by immobilisation in cases of intrusive luxation of teeth with closed apices. Clinical cases are presented.

[In what way does the diet of our children affect oral-dental health? Results of a survey on the diet of school children in Louvain].

The nutritional habits of 157 schoolchildren, aged between 6 and 12 years, were recorded during a period of 7 consecutive days. The nature of food substances, the frequency of snacks between meals, the frequency of sugar intake and toothbrushing habits were evaluated. The overall response was good. Results show that three out of four children take cariogenic food substances for their breakfast. Almost half of the drinks are highly cariogenic, containing large amounts of sugar. The daily frequency of between-meal snacks lies between two and three. About 10% of the forms show a frequency of sugar intake higher than 5 per day and in more than 10% the toothbrushing frequency is zero.

Blood loss following dental extractions in anticoagulated rabbits: effects of tranexamic acid and socket packing.

The present study demonstrates the feasibility of chronic anticoagulation in rabbits and of estimating the resulting increase in blood loss following extraction of four front teeth from labeled red cell disappearance curves. This setup proved useful for the evaluation of hemostatic techniques. Socket packing with oxidized cellulose soaked in thrombin solution or local application of cyanobutylacrylate reduced early blood loss; oral administration of tranexamic acid reduced both early and late bleeding; the combination of socket packing and oral tranexamic acid completely abolished the excessive blood loss that resulted from anticoagulation alone.

Dental extractions in hemophilia: reflections on 10 years' experience.

During the past ten years we have witnessed a remarkable reduction in complications following dental extractions in patients with hemophilia. Thirty-six of 100 patients experienced delayed bleeding during the first half of this period; fourteen of 112 patients had a hemorrhagic problem after extraction during the second half. From a major undertaking involving hospitalization and general anesthesia, it has become a simple procedure in the outpatient office. During the entire period, no changes were made in the transfusion policy or in the oral administration of antifibrinolytic agents. Factors contributing to the favorable evolution have been the increasing experience of the oral surgeon, the improving dental status of our hemophilia patients, prophylactic measures to reduce gingival inflammation, and changes in the composition and amount of material used to pack the dental sockets.
