Facioscapulohumeral muscular dystrophy is clinically mainly characterized by progressive weakness of the facial, shoulder and upper arm muscles. It is an autosomal dominant heriditary disease, caused by a contraction of a repetitive DNA element at the end of the long arm of chromosome 4. This contraction causes the local relaxation of the chromatin structure and likely dysregulation of one or more genes. Oral health care providers can play a significant role in the early recognition, as the often asymmetric facial weakness is frequently the first symptom. Adequate oral health care is needed because of the facial weakness.

A patient experienced severe bleeding in the floor of the mouth as a consequence of the placement of 2 implants in the resorbed anterior segment of the mandible. The resulting swelling of the floor of the mouth caused a life-threatening obstruction of the trachea. The patient was urgently transferred to a hospital. Treatment there consisted of the administration of medication and intensive observation. In the literature an intubation or the carrying out of a tracheotomy with possible surgical interventions is also described. The cause lay in damage to the lingual cortical plate of the mandible and trauma of the underlying vascular structures. Especially the cuspid and bicuspid regions are vulnerable because of the often seen lingual concavity in the processus alveolaris. Serious atrophy of the processus alveolaris is also a predisposition. To reduce the probability of such complications knowledge of the local anatomy, good clinical inspection and various radiographic evaluations are important. In case of obstruction of the trachea it is of vital importance to immediately transport the patient to the nearest hospital for further treatment.

Periodontitis and periimplant infections are complex manifestations associated with several disease-modifying factors, such as causative pathogens and smoking. Although research into these factors has led to important progressions in the treatment of these infections in recent decades, the contribution of mental stress in the absence of pathogens or smoking is still unclear. Qualitative and quantitative assessment of mental stress might be an important instrument in periodontal and periimplant therapy.
 

Many dental students in the Netherlands have a job in a dental practice next to their study, as the Individual Health Care Professions Act (introduced in 1997 as Law BIG) allows. The aim of the study is to determine how many dental students actually work in a dental practice, which kinds of dental activities are performed by them and whether these meet the requirements of the Law BIG. All dental students (n = 947) at the Academic Centre for Dentistry Amsterdam (ACTA) received a questionnaire by e-mail. The response was 44% (427 students). Of these students, 71% had a job next to their study; 25% worked in a dental practice. Study progress and age were positively correlated with working in a dental practice. Their activities mainly involved chair assistance, giving brushing instructions and fluoride applications, and dental cleaning. These students appeared to be better informed about the Law BIG than other students. The source of this information was not, however, the practice where they worked. It was evident, moreover, that they felt the need for more information concerning the delegation of restricted dental activities.

The aim of this study was to measure Dutch oral surgeons’ levels of burn-out risk and the contributing role of demanding working conditions. In addition, the extent of work engagement was considered, and which stimulating working conditions contributed to it. All 179 Dutch oral surgeons registered in the Dutch Dental Association’s files received a questionnaire by means of which burn-out, work engagement and both demanding and stimulating aspects from the work environment could be measured. Based upon a 70% response, it can be concluded that Dutch oral surgeons have a relatively low risk of burn-out and a high degree of engagement. Demanding working conditions which explain the differences in the risk of burn-out are: ‘Pressure of work and clinic organization’, and ‘Lack of variation and perspective in work’. Differences in enthusiasm were best explained by ‘Variety in work’, and ‘Positive effect upon patients’. It is remarkable that the mean for all demanding aspects of work is relatively low and the mean for all stimulating aspects is relatively high.
