Total tooth loss among persons aged > or =65 years--selected states, 1995-1997.
Loss of all natural permanent teeth (edentulism) substantially reduces quality of life, self-image, and daily functioning. Although loss of teeth results from oral diseases such as dental caries and periodontitis, it also reflects patient and dentist attitudes, availability and accessibility of dental care, and the prevailing standard of care. One of the national health objectives for 2000 is to reduce to no more than 20% the proportion of persons aged > or =65 years who have lost all their natural teeth (objective 13.4). Edentulism has been declining in the United States since the 1950s, but few state-specific data are available on adult tooth loss. To estimate the prevalence of edentulism among persons aged > or =65 years, CDC analyzed data from the 46 states that participated in the oral health module of the 1995-1997 Behavioral Risk Factor Surveillance System (BRFSS). This report summarizes the findings from this analysis, which indicate a large state-specific variation in edentulism and that many states have not yet achieved the national health objective for preventing total tooth loss.

Post-extraction remodeling of the adult mandible.
Following tooth loss, the mandible shows an extensive loss of bone in some individuals. This may pose a significant problem in the prosthodontic restoration of function and esthetics. The many factors which have been proposed as being responsible for the inter-individual variation in post-extraction remodeling mean that a perfunctory analysis of the literature, in which well-controlled, relevant studies are scarce, may not provide the whole story. This article reviews the local and systemic factors which may play a role in the post-extraction remodeling of the mandible. Since severe residual ridge resorption may occur even when the bone status in the rest of the skeleton is good and vice versa, it is concluded that local functional factors are of paramount significance. It is now essential to determine how they can be modified and applied to help maintain ridge height and quality in our aging, edentulous population. (+info)
Autogenous tooth transplantation: an alternative to dental implant placement?
Autogenous tooth transplantation, or autotransplantation, is the surgical movement of a tooth from one location in the mouth to another in the same individual. Once thought to be experimental, autotransplantation has achieved high success rates and is an excellent option for tooth replacement. Although the indications for autotransplantation are narrow, careful patient selection coupled with an appropriate technique can lead to exceptional esthetic and functional results. One advantage of this procedure is that placement of an implant-supported prosthesis or other form of prosthetic tooth replacement is not needed. This article highlights the indications for autogenous tooth transplantation using 3 case reports as examples. A review of the recommended surgical technique as well as success rates are also discussed. (+info)
Tooth loss in periodontal patients.
OBJECTIVE: To compare tooth loss between patients who received surgical therapy for chronic periodontitis and those who received nonsurgical therapy alone. METHODS: A retrospective chart study was conducted at Dalhousie University. All patients who had periodontal treatment and were active cases for at least 10 years were included (n = 335). The sample consisted of 120 males (35.8%) and 215 females (64.2%). Ages ranged from 16 to 77 (mean = 46.1 +/- 12.0 years). All patients received nonsurgical therapy; 44.8% received periodontal surgery as well. Variables recorded were demographics, initial attachment loss, treatment type, recall frequency, patient compliance and history of extracted teeth. Independent t-tests or chi-squared tests were used to compare these for surgical and nonsurgical patients. ANOVA was used to test for interactions between initial attachment loss, age, gender, compliance and type of therapy a patient received as reasons for tooth loss. RESULTS: 521 teeth were lost in 69 patients (20.6% of sample). Of teeth lost, 61.8% were due to periodontal disease; 24.8% to caries; 13.2% to other reasons. Patients initially diagnosed with early attachment loss lost an average of 0.37 (+/- 1.33) teeth. Patients diagnosed with moderate attachment loss lost an average of 1.50 (+/- 2.54) teeth and those diagnosed with advanced attachment loss lost an average of 3.11 (+/- 3.01) teeth. Those who received surgical therapy lost more teeth (mean = 1.31 +/- 2.36) than those who received nonsurgical treatment (mean = 0.68 +/- 1.87; p = 0.001). However, initial attachment loss was the only factor that could predict tooth loss. The type of therapy (surgical or nonsurgical) was not statistically significant. CONCLUSIONS: Most periodontal patients (79.4%) who received treatment at this dental school clinic did not lose any teeth due to periodontal disease over at least 10 years. Although patients who had surgical therapy lost more teeth than those who had nonsurgical therapy alone, this was not an important predictor of tooth loss. (+info)
Ridge augmentation using mandibular tori.
A 19-year-old female was referred by her dental practitioner for the restoration of missing maxillary lateral incisors and canines. Ridge augmentation was required. This was undertaken using mandibular tori as the sites for harvesting bone. The grafting was successful and the spaces were subsequently restored using resin-bonded bridgework. The case reports that mandibular tori provide a local and convenient source of bone for ridge augmentation procedures. (+info)
Developing an index of restorative dental treatment need.
The process undertaken to establish an initial pilot index for restorative dental treatment is described. Following consultation with a wide range of clinicians and others, an outline framework for the index was developed and comprised three main components: 1. Patient identified need for treatment: the data from the patient perceived need questionnaire were inconclusive; 2. Complexity of treatment (assessed by clinicians): this was found to be a practical tool capable of being used by a range of dentists. A booklet has been produced which describes the process of using the scoring system; 3. Priority for treatment (assessed by clinicians): three levels of priority were identified; the highest priority was assigned to patients with inherited or developmental defects that justify complex care (eg clefts of the lip and palate). The initial development of the index has had some success in a difficult area. The treatment complexity component is the most developed and may allow both referrers and commissioners of specialist restorative dentistry to determine appropriate use of skilled clinicians' expertise.

Good occlusal practice in children's dentistry.
The difference between paediatric dentistry and most other branches of dentistry is that in the child the occlusion is changing. Consequently 'Good Occlusal Practice' in children is a matter of making the right clinical decisions for the future occlusion. The clinician needs to be able to predict the influence that different treatment options will have on the occlusion when the child's development is complete. (+info)
Epidemiological study on improving the QOL and oral conditions of the aged--Part 1: The relationship between the status of tooth preservation and QOL.
In part 1 of this epidemiological study, a survey was conducted for all senior citizens aged 70 and over who resided in a mountainous village in the mid-section of Hyogo Prefecture. It focused on the relationship among the number of existing teeth, life environment, health status, and activities of daily living; and the correlation between oral status and QOL was analyzed. The daily activities of individuals were compared between those having one or more teeth and others who were totally edentulous. Subsequently, it was found that for both males and females, the odds ratio was significantly high for the dentulous individuals, in comparison with edentulous individuals, to exhibit a behavior indicative of a better QOL (such as "opportunity for conversation with family members or others)", "regular physical activities", and "attend meetings or group outings"). The result of this survey indicates that the presence of teeth is very closely related to one's daily activities. It was concluded that preventing tooth loss is vital for maintaining the masticatory function; so to prevent tooth loss, periodontal disease must be averted. (+info)
