[Microstomia as a complication of scleroderma].

Scleroderma is a rare connective tissue disease of unknown origin. It is characterized by increased collagen deposition leading to fibrosis and degeneration of the skin and sometimes of internal organs. There are two main groups of scleroderma: circumscribed scleroderma and systemic sclerosis. Circumscribed scleroderma is limited to the skin and systemic sclerosis has involvement of internal organs. The main oral manifestation of scleroderma is microstoma, which is a limiting factor in oral selfcare and professional oral health care. A case report is presented of the treatment of a 15-year-old female scleroderma patient with microstoma.

[Oral health of community-dwelling elderly. 2. The subjective aspect of oral health].

In this study oral health of elderly persons as perceived by the subjects was evaluated. Phenomena often mentioned were problems with chewing and biting, dry mouth, retention of food particles between teeth or below the prosthesis, (in edentates) sensitivity of teeth for warm or cold foods and (in edentates) lack of retention of the lower prosthesis. In a lot of persons these problems affect quality of life.

Success of dental implants in elderly people--a literature review.

Implant-supported dentures seem particularly appropriate for the predicament of being elderly and becoming edentulous. The aim of this article was to review the literature on success of dental implants in elderly people. The results of two studies suggested that the treatment with implants can be considered safe and predictable for older as well as for younger patients. Three studies found no increased implant failure-rate in patients with a compromised medical status. Four studies revealed high success-rates of dental implants among groups of elderly people. Within the limitations of this review of the literature it can be concluded that old age does not seem to represent a factor of major prognostic significance in treatment with dental implants.

[Male fertility. Possibly affected by occupational exposure to mercury].

In the last decades there is circumstantial evidence for an increased incidence of cryptorchidisme and hypospadia in new-born boys and an increased incidence of testicular cancer in adults. Moreover, there are indications that sperm quality is declining. Exposure to endocrine disrupters in utero and during adulthood is a possible explanation for the impairment of male reproductive health. Exposure to mercury may lead to deposition in the pituitary gland and the testicular tissues causing impairment of testicular function, especially spermatogenesis. Evidence based research is needed.

[Oral health of community-living elderly. 1. Condition of teeth, use of professional dental care and oral hygiene habits].

With the aim to get information on oral health, professional dental care and oral hygiene habits a study was performed on persons aged 60 up to 79 years in Haarlem, the Netherlands. After an interview an oral examination was performed, using a mirror and a pocket lamp. Of all persons approached, 376 (38%) participated in the clinical part of the study. In elderly persons with natural teeth (52% of all participants) the mean numbers of present teeth (third molars excluded), FT and obvious DT were 18.1, 10.8 and 0.7 respectively. The percentage of persons with natural teeth showed a strong relationship with level of education. A comparison with results of a study performed in 1986 showed that oral health in elderly persons is improved. Of all the elderly with natural teeth 91% visited their dentist periodically at least one time a year and 76% of them brushed their teeth at least two times a day.

[Overdentures covering natural roots. The use of chlorhexidine gel].

To prevent caries and periodontal disease in overdenture abutment teeth, daily application of chlorhexidine gel is recommended. In order to get insight into the use of the gel, 29 overdenture wearing patients were interviewed. In addition the patients were requested to show the use of the gel. It was concluded that at any time the patients were instructed about the use of the gel. Nevertheless, a majority of the patients did not use the gel daily and in accordance with the instructions given. Application of the gel in the abutment depressions of the overdenture appeared to be a heavy task.

[Aging, a frightening image of dental health?].

The combination of decreasing oral self-care and increasing risks of oral health make elderly people an oral health risk-group. In many elderly people above the age of approximately 75 the decline in functions culminates in infirmity. Frail and infirm elderly people require geriatric care, but often oral health care is not an integral part of geriatric care. Geriatric oral health care could be promoted and encouraged by dental hygienists. Unless geriatric oral health care will be promoted, ageing and especially dependent ageing seems a spectre of oral health.

Professional hygiene care, adjustments and complications of mandibular implant-retained overdentures: a three-year retrospective study.

PURPOSE: This report presents a retrospective evaluation of postinsertion care required by 104 edentulous patients with advanced mandibular bone loss. MATERIAL AND METHODS: The patients were treated with new maxillary dentures and mandibular overdentures retained by two implants with a single bar-clip attachment. Distinction was made between professional hygiene care, adjustments, and treatment of complications. The follow-up period after insertion of dentures was 3 years for all patients. RESULTS: Approximately a third of the patients needed professional hygiene care. The need for adjustments declined during the years of function. Complications were encountered in approximately a third of the patients. The majority of these were not related to the implants, but to the superstructure and both the maxillary and mandibular dentures. CONCLUSIONS: Many edentulous patients with advanced mandibular bone loss who were treated with mandibular implant-retained overdentures need professional hygiene care, adjustments, and treatment of complications.

"Prosthetic condition" and patients' judgment of complete dentures.

PURPOSE: This study introduces the concept "prosthetic condition", which combines the quality of complete dentures and residual alveolar ridges. MATERIAL AND METHODS: A pilot study was performed to select quality criteria with an acceptable interobserver agreement. With these criteria, a clinical examination was performed to assess the quality of the existing complete dentures and the residual alveolar ridges of 397 complete denture wearers. During clinical examination, the interobserver agreement of the selected criteria was retested. The "prosthetic condition" was assessed by combining the scores for denture quality and quality of the residual alveolar ridges. Subsequently, participants' satisfaction with and complaints about their dentures were scored according to their answers to specific questions. RESULTS: Logistic regression analysis demonstrated that no variable of the "prosthetic condition" proved to explain the denture satisfaction. Some variables of the "prosthetic condition" had a significant but not relevant correlation with some denture complaints. CONCLUSIONS: More research is necessary to substantiate the concept "prosthetic condition" as an acceptable measure of professionally quality assessment of dentures and denture-bearing surfaces. However, in determining the treatment need of community-dwelling groups, this concept seems a more realistic measure than denture quality only.

Geroprosthodontics: The Nijmegen and Manchester Dental Schools approach.

If quality of care for elderly patients is to be achieved, thorough and realistic geroprosthodontic treatment planning is essential. This requires mature consideration, incorporating comprehensive patient assessment and selection of the most appropriate treatment option for each patient. The latter should be based on criteria which meet the demands of a healthy dentition and which enable a patient to achieve satisfactory oral function. The Nijmegen and Manchester Dental Schools have evolved simple patient-related treatment guidelines. These start with a problem-oriented approach which leads to a provisional treatment. The provisional treatment is intended to result in a healthy dentition that is monitored over an appropriate period. Evaluation of the provisional treatment leads to three options: extension of the monitoring time, preservation of the natural occlusion or loss of the natural occlusion. Definitive prosthodontic treatment plans are based on the second or third option. In the maintenance of good oral health after prosthodontic treatments, plaque and diet control are essential elements. Recall or maintenance programmes must be carried out if successful treatment is to be achieved and maintained.

[Serious periodontal destruction in the elderly. Intensive treatment or an overdenture prosthesis?].

A minority of dentate elderly people have advanced periodontal disease. Is both non-surgical and surgical periodontal treatment or overdenture treatment the therapy of choice? Research data comparing these treatments, from patients' or professionals' point of view, are as yet not available. Concerning efficacy and cost-effectiveness, overdenture treatment appears to be superior to periodontal treatment.

[Occlusion repair or occlusion loss? Results of preliminary treatment as the starting point].

Epidemiological data confirm that the number of elderly with an impaired dentition is increasing. The treatment of patients with an impaired dentition should be focused on maintaining oral function during life-time. However this goal is hardly achievable because of the complicating factors in an impaired dentition. This article describes the Nijmegen Dental School approach in the treatment of impaired dentition and stresses the importance of the preliminary treatment in order to answer the question whether restoring or extracting teeth is the most appropriate treatment modality.

[Tooth wear. Classification and terminology].

Tooth wear rarely occurs as a result of one factor alone. Non-carious loss of tooth tissue can be subdivided into attrition, demastication, abrasion, fractionation, and erosion. Clinically, the tooth tissue loss may result from any combination of these types of wear. The first essential principle in the management of tooth wear is, as far as possible, to remove the cause. Secondly, restoration may be indicated.

[Adjustment of complete dentures. Have oral stereognosis and denture quality a predictable value?].

The denture complaints of 397 complete denture wearing participants were assessed. The quality of the dentures and denture bearing surfaces were professionally scored as well. Combination of these scores gave a specific denture quality, the so-called 'prosthetic condition'. The oral stereognostic capability was recorded with an Oral Stereognosis Test. There was no correlation between denture complaints and the results of the Oral Stereognosis Test, nor between denture complaints and prosthetic condition.
