ABSTRACT
Oral and maxillofacial surgeons and hospital dentists are often requested to perform a dental focus examination in patients (to be) admitted in a hospital and for whom the state of their teeth is of importance for a medical treatment or situation. The main reasons for a dental focus examination include unexplained fever, heart surgery, chemotherapy, organ or artificial joint transplants, use of oral or intravenous bisphosphonates and radiotherapy of the head and neck. In daily practice, there is a need for a clear algorithm which is easy to apply for the diagnosis and treatment of dentalfoci for the various medical indications. The medical conditions described above have in common that subclinical infections can lead to complications under exceptional conditions. The influence and the nature of the development ofa dental infection varies in each of the situations mentioned. This has consequences for the need to eliminate dentalfoci. The diagnosis and treatment of dental foci in relation to various medical situations therefore requires a nuanced approach.

Occasionally a dentist is confronted with a painful, red facial swelling which has suddenly appeared, with no signs of a dental cause. In addition to the other possible causes, one should consider the possibility of an insect bite, especially in the summer months. The consequences of an insect bite or sting are often underestimated. Hymenopterae (wasps and honeybees) stings are not generally serious in nature, but can result in severe systemic medical complications, such as an allergic reaction. Dentists who are confronted with a patient with an insect bite or sting must provide the patient with adequate information and if necessary take measures in order to prevent further complications.

Noonan syndrome is a relatively common autosomal dominant genetic disorder which is characterised by typical facial features, congenital heart diseases and small stature. In 50% of the cases the syndrome is caused by a mutation on the PTPN11-gen. The expression of symptoms associated with Noonan syndrome can be very mild in nature and facial features usually become less pronounced with age, which can sometimes make a correct diagnosis more difficult. Despite a wide range of associated symptoms most adults with Noonan syndrome can be self-sustaining, with a good quality of life. It is important that the dentist is well-informed about this syndrome due to the heart diseases and bleeding disorders which can be present with these patients and may influence a dentist's choice of therapy when invasive treatment is indicated.

The objective of this study was to review the literature and compare different surgical methods for the management of coronoid process hyperplasia. A literature search was performed for publications since 1995. Case characteristics were extracted (age, sex, duration of symptoms, form, maximal mouth opening and treatment) and entered into a database for analysis. The data were split into two groups (coronoidectomy and coronoidotomy). Maximal mouth opening measurements before and after surgery were analyzed with several statistical tests. 61 cases were entered into the database. The mean age was 23 years and mean duration of symptoms 7 years. The bilateral form occurred 4.1 times more frequently than the unilateral form. The male-female ratio was 3.3 to 1. In 94% of the cases the approach was intra-oral. 84% of the cases received a coronoidectomy. Statistical analysis showed that the preoperative and postoperative differences between the groups were significant. The results were not significant when corrected for the preoperative difference. Postoperative therapy was not comparable due to heterogeneity. Cases that received a coronoidotomy had slightly better postoperative results.

New haematopoietic stem cell transplantation procedures make the treatment available to patients who previously did not qualify, such as the elderly. In addition, the spectrum of oral complications associated with haematopoietic stem cell transplantation has altered as a result of the recent developments. This article is a review of the main principles of haematopoietic stem cell transplantation and provides information on oral complications which may develop, such as mucositis, infections, bleeding, graft-versus-host disease, xerostomia, hyposalivation, altered taste, secondary tumors, osteoporosis, osteonecrosis and growing and developing disturbancies. Finally, the role of dental care providers in cases of haematopoietic stem cell transplantation is addressed.

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.

Although not scientifically proven, dental foci are believed to result in severe local or systemic disease. Eradicating dental foci in order to prevent possible interference with a medical treatment may be important in specific patient groups. To gain insight in the number of dental focus examinations, the medical evidence, the number of potential foci determined, as well as the treatment eradicating the focus, all dental focus examinations in 16 Dutch hospitals were registered during 3 months. A total number of 470 examinations were performed. Scheduled heart(valve)surgery and radiotherapy of the head and neck were the main reasons for a dental focus examination. Dental foci were found and treated in more than 50% of the patients examined. There was a significant difference between dentate and edentulous patients in the percentage of patients diagnosed and treated for a dental focus. More than 80% of dentate and less than 20% of edentulous patients were treated.

The aim of this study was to establish surgical guidelines based on the growth pattern of ameloblastomas in relation to the possible infiltration of the cortical bone, the inferior alveolar nerve, the periosteal layer and the surrounding soft tissues. Five male patients with voluminous mandibular ameloblastomas were treated by means of radical surgery. Ameloblastomas showed an invasive growth pattern in the cancellous bone with small tumour nests at a maximum distance of 5mm away from the bulk of the tumour. Expansive and invasive growth in the Haversian canals was observed. There was no invasion of the inferior alveolar nerve. The mucoperiosteal layer was invaded but not perforated. No invasion was observed in the surrounding soft tissues of the periosteum and in the skin tissue. A local resection with a surgical margin of spongious bone of 1cm is suggested. When the tumour is radiologically closer than 1cm to the inferior border of the mandible, a continuity resection is mandatory. A conservative approach concerning the inferior alveolar nerve is suggested. Removal of an excess of perimandibular soft tissue is not indicated. The overlying attached mucosal surface should however be excised together with the underlying bone.

Central giant cell granuloma (CGCG) is a benign lesion of the jaws with a sometimes locally aggressive behaviour. The most common therapy is surgical curettage which has a high recurrence rate, especially in lesions with aggressive signs and symptoms (i.e. pain, paresthesia, root-resorption and rapid growth). Alternative therapies such as interferon alpha (INFalpha) or calcitonin are described in the literature. In this study 2 patients with an aggressive CGCG are presented who were treated with INF mono-therapy. INF mono-therapy was capable of terminating the rapid growth of the lesion in both patients and induced a partial reduction. Total resolution, however, was not obtained and alternative treatment is still necessary.

Corticosteroids are produced in the adrenal gland cortex and are subdivided in mineralocorticosteroids and glucocorticosteroids. Usually, corticosteroids are prescribed as drugs to replace natural corticosteroids in case of insufficient functioning adrenal glands and in numerous diseases because of their anti-inflammatory and immunosuppressive effects. Based on literature data, it was concluded in this article that corticosteroids are never indicated as a preventive measure in regular dentistry and oral and maxillofacial surgery. Only in cases of major elective oral and maxillofacial surgery, prescription of corticosteroids may be considered.
