[Dental care of the elderly. An inquiry on the status of dental welfare in the old age and nursing homes as well as in the geriatric medical clinics of Basel-Stadt and Basel-Land cantons].

63 old people's and nursing homes, and 7 geriatric health clinics from the cantons of Basel-Stadt and Basel-Land were surveyed to determine their current level of dental care. The results regarding the old people's homes and nursing homes are in line with those obtained in the Franscini (1984) survey of 113 homes for the aged in Zurich: only a few isolated institutions conducted dental examinations and administered treatment, and only a few of them employed a dental hygienist to instruct and supervise the oral hygiene of the residents. A mere three geriatric health clinics and one old people's home in Basel-Stadt have a dental care unit. The nursing personnel is largely responsible for maintaining the pensioners' oral hygiene although these employees have received insufficient or no training for such work. The replies received indicate that an improvement in dental care is urgently needed, especially in the old people's homes and nursing homes, with absolute priority to be given to the promotion of oral hygiene.

[Bonding strength of metal frameworks and adhesive agents in the resin-bonded bridge technic. 3. Comparative research on various retention mechanisms and adhesive systems].

In fixed denture prosthetics, macro- and micromechanical as well as chemical adhesive mechanisms may be used between metal and bonding agent. The in vitro research presented here determines the adhesive strength of six different bonding agents and five different retention mechanisms on twelve precious and nonprecious metal alloys using shearing stress. The evaluation of the results should help to assess the suitability of the various combinations of materials and anchoring methods for the fixation of adhesive bridges. On the basis of the adhesive strengths and the examination of the various clinical advantages and disadvantages of the different methods that were analyzed, the electrolytic etching of nonprecious metal alloys appears to be particularly suitable for fixed denture prostheses. An efficient combination between alloy and bonding agent is of particular importance in this area. Macromechanical mesh and negative retentions can only be used to a limited clinical extent due to their high space requirements. Very good results were produced by the preconditioning of inner anchor surfaces with silanes. Sandblasting, however, provided unsatisfactory shear-stress results over a broad front independently of the type of alloy.

[The oral hygiene, dental health and prosthetic care of old age home pensioners and geriatric patients. A study at the Adullam Foundation in Basel].

To determine the current state of oral hygiene, dental health and prosthetic appliances among residents of nursing homes and geriatric hospitals, 100 nursing home residents and 53 hospital patients with an average age of 82 were interviewed and examined in the Adullam Foundation in Basle. Only about 30% of those questioned expressed problems related to chewing, and only about 15% were dissatisfied with their dentures. Hardly any material other than toothbrush and toothpaste was used for dental hygiene. Only 38% of the nursing home residents and as few as 15% of the hospital patients brushed their teeth three times daily. A good 46% of the nursing home residents still possessed at least one original tooth. The incidence of plaque was categorized as high. In more than 86% of the cases, flaws were determined in removable prosthetics. Dental treatment was considered immediately necessary in 2% of the cases and necessary in 41%. In order to improve oral hygiene and dental care among aged nursing home residents in Switzerland, a list of suggestions has been compiled.
