Tobacco and oral health: attitudes and opinions of European dentists; a report of the EU working group on tobacco and oral health.

AIM: To discover whether dentists are prepared to advise their patients to stop smoking. DESIGN: Postal questionnaire. SETTING: Member countries of the European Union. PARTICIPANTS: Dentists in 12 EU countries. MAIN OUTCOME MEASURES: Dentists' knowledge of links between tobacco-use, general health and periodontal health. Knowledge of, and preparedness to offer, tobacco-cessation activities for patients. Personal and practice smoking policies. RESULTS: EU-dentists are aware of the harmful effects of tobacco use in general and on oral tissues in particular. Over two-thirds of EU-dentists feel that offering information about tobacco cessation is the dentist's duty, while slightly less actually do so. Lack of time and reimbursement mechanisms are the most often mentioned barriers for co-operation with a campaign. Less than 10 per cent of EU-dentists smoke every day while three-quarters of practices are totally smoke free. CONCLUSIONS: EU-dentists want to be informed and supported on the issue by leaflets, brochures, continuing education and patient education materials. More attention should be paid to the relation of smoking and implant failure.

[Are dentists willing to advise their patients to quit smoking?].

In order to know whether dentists are prepared to advise their patients to stop smoking, a representative study was performed in several EU-countries. From the Dutch results, it may be concluded that dentists in the Netherlands are aware of the harmful effects of tobacco use. They are prepared to pay more attention in their dental practice to these harmful effects for general health and for oral health in particular. The majority is willing to participate in a smoking cessation campaign, provided there is more information about 'why' and 'how'.

[Legal aspects of the administration of local anesthesia in dentistry].

In this article the various legal aspects of the administration of local anaesthetics in dentistry are discussed. In general, a capable dentist is not liable for complications resulting from the administration of local anaesthetics, unless the complications could have been foreseen and prevented.

Autologous versus homologous bone grafting in osteotomies, secondary cleft repairs and ridge augmentations: a clinical study.

To compare the clinical results, complications and morbidity of osteotomies, secondary cleft repairs and ridge augmentations in which frozen femoral head homologous bone or autologous bone was used, a series of 61 patients with follow-up periods of 1 to 6 years has been reviewed. Long-term clinical observation shows that, with a correct indication and surgical technique, frozen homologous bone is a good alternative to autologous bone in clinical grafting procedures.

Thyroglossal cysts in patients over 30 years of age.

8 patients over 30 years of age with a thyroglossal cyst, who had not been operated on before and who underwent excision of the cyst by a Sistrunk procedure, are described. In 8 additional patients, a wait-and-see policy was adopted. Follow-up data of these 16 patients are reported 1.5-14 years after their last visit to the hospital. There were no recurrences in the group of treated patients. In the group of untreated patients, the cyst remained unchanged in 1, decreased in size in 3 and disappeared completely in the remaining 4 patients. The present study indicates that removal of a thyroglossal cyst in patients over 30 years of age is not obligatory.

Oral manifestations in Cowden's syndrome. Report of four cases.

Cowden's syndrome or multiple hamartoma and neoplasia syndrome is a hereditary disorder combining multiple hamartomas of many organs. These hamartomas are derived from ectodermal, mesodermal, and endodermal tissues and may undergo spontaneous malignant changes. Small papular cutaneous lesions and papillomatous outgrowth and papular lesions of the oral mucosa are the most predominant features of the syndrome. Since the orocutaneous lesions often precede the associated malignant degenerations, they may serve as a diagnostic signal for the probably developing neoplasia in other organs. The presence of extensive papillomatous and papular lesions in the oral mucosa combined with skin lesions should therefore alert the clinician to suspect the presence of Cowden's syndrome, the early diagnosis of which is important in order that the concomitant malignant changes might be discovered at the earliest possible moment. Four cases of Cowden's disease are presented, with emphasis on the oral manifestations of this syndrome.

Subperiosteal onlay augmentation of the mandible: a clinical and radiographic survey.

A five-year follow-up study of 26 patients who underwent subperiosteal onlay augmentation of the mandible using corticocancellous bone from the iliac crest is presented. An overall postoperative reduction in mandibular height of 44% was found. The different rates of resorption between the various suggested augmentation methods are discussed, and suggestions are given to prevent the rapid resorption that occurs during the immediate postoperative period.

Encysted parasitic larvae in the mouth.

Oral appearances of intestinal parasitic disease are rare. One such appearance is the presence in oral tissues of encysted or encapsulated larvae of organisms from the classes Cestoidea and Nematoda. Cestode larvae form cyst-like lesions that are often clinically diagnosed as mucoceles. In these lesions, the cyst cavity is lined by fibrous tissue with inflammatory cells, and contains fluid and the larval stage of a parasite. The diagnosis of these parasitic cysts is more frequently made in younger persons. The cysts may be treated by simple excision, but care must be taken that the cyst does not rupture, as in some parasites this may result in new cyst formation. Nematode infection in the oral cavity, the most common of which appears to be trichinosis, is rarely reported. Patients with oral or maxillofacial (or both) parasitic disease must undergo a thorough medical investigation to exclude possible life-threatening involvement in other parts of the body.

Unusual healing of a fracture of an atrophic mandible. Report of a case.

Fractures of an atrophic edentulous mandible may present a serious problem in oral surgical treatment. A case is described in which a traumatic mandibular fracture, initially treated by means of a Gunning type of splint, and a subsequent spontaneous fracture on the opposite side were treated without mechanical fixation.

Mucosal antral cysts. Review of the literature and report of a radiographic survey.

The increased use of panoramic radiography in dental practice has brought about the coincidental detection of abnormalities in the maxillary sinus, especially cysts of the mucosal lining. In our material of 1,080 patients, an incidence of 8.7 percent was found. Males were affected significantly more than females. The literature is reviewed regarding terminology, etiology, frequency, and radiologic and microscopic findings of those cysts.

Nasopalatine duct cyst. Review of the literature and report of 22 cases.

The nasopalatine duct cyst is the most common non-odontogenic cyst in the oral area. The literature is reviewed regarding terminology, epidemiology, etiology, radiology, microscopic findings and treatment of these cysts, and is followed by a discussion of the data of 22 patients. A correct diagnosis can only the made after proper clinical, radiographic and histopathologic examination.
