The medical history of a 46-year-old man recorded osteomas in the maxillary bone 18 years before, haemorrhoids, and kidney stones. He presented with pain in the right lower abdomen and rectal blood loss. His complaints were diagnosed as familial adenomatous polyposis, culminating in sigmoid carcinoma. Due to the extent of the polyps and, consequently, the great cancer relapse risk, a surgical treatment was indicated. A symptom of a familial adenomatous polyposis variant, Gardner’s syndrome, is osteomas in the orofacial region. Dentists and oral surgeons should be aware of this rare syndrome in a patient with orofacial osteomas, especially if the patient has a familial risk of adenomatous polyposis.

A 60-year-old man with an edentulous maxilla was referred by his dentist to an allergy clinic with complaints of burning mouth and bad taste. In the majority of cases, it is hard or impossible to detect the cause of burning mouth. In this case, ultimately the complaint could be solved by eliminating exposure to feasible allergenic components of denture base resins.

Heroin is a half synthetic opiate with. It is used by a relatively small number of the general population, but relatively frequently by homeless people and prisoners. Since heroin has an inhibitory effect on the nervous system and on breathing, an overdose of heroin can have fatal consequences. Sudden abstinence of heroin results in general discomfort, restlessness, muscle cramps, perspiration, nausea, shivers and goose bumps. Oral effects of heroin include increased risks of caries, periodontitis and bruxism. Saliva has the potential of detecting heroin abuse.

In the 1990s the Dutch government imposed several laws to strengthen the position of the patient and to improve the quality of care. These laws did not always have the intended outcome. Recently the Ministry of Public Health, Welfare and Sport launched the programme, ‘The 7 rights of the patient in health care: investing in health care relations’. Three of these rights will have a strong influence on Dutch general dental practices: the right to choice and choice-information, the right concerning coordination among oral health care providers, and the right to low-threshold complaint and disagreement procedures. Most of these rights already exist in current legislation. Especially the right to choice and choice-information means that the dentist has to provide his patients not only with information concerning treatment but also with information on his dental practice, such as waiting times, the experience of other patients and opening times.

Apical endodontic surgery is applied frequently following a failed conventional endodontic treatment. The apical preparation can be carried out conventionally using a round bur or using an endodontic ultrasonic system. The purpose of this study was to compare the outcome of the 2 treatment options by a randomized prospective clinical study. Patients (n = 399) were at random allocated to treatment using a conventional round bur or using an ultrasonic system (P-max Newtron®) according to a for the rest similar treatment protocol. One year post treatment, the treatment outcomes were determined by 2 oral and maxillofacial surgeons, blinded for the treatment option. Adequate follow-up data were obtained from 290 patients. The overall success rate was 71% in the patients treated conventionally and 81% in the patients treated using the ultrasonic system. In molar teeth, the difference in success rate was statistically significant.

The Dutch Dental Association (NMT) surveyed dentists who graduated in 2004, 2005 or 2006 concerning their work situation and plans for the future. They were also asked about their experiences at the start of their career. In general, the recently graduated dentists did not face difficulties at the start of their professional life. Most dentists worked in the practice of a colleague, but the majority ultimately wanted to have their own practice. The latter applied more to men than women. Furthermore, there was a clear preference for working within a team and most of them planned to specialize in a specific branch of dentistry. The survey also revealed that the delegation of tasks to dental hygienists and prevention assistants was more or less taken for granted by recently graduated dentists.
