Gingival recession-its significance and management.

OBJECTIVES: To review the prevalence and current concepts of the mechanisms and aetiology of gingival recession and present the principles of assessment and management of the patient with gingival recession. DATA AND SOURCES: The literature was searched for review and original research papers relating prevalence, mechanisms, aetiology, assessment, and treatment of gingival recession using Medline and manual tracing of references cited in key papers otherwise not elicited. STUDY SELECTION: Studies with gingival recession as focus and pertinent to key aspects of review. RESULTS: Gingival recession is a common condition and its extent and prevalence increase with age. Many factors including trauma and periodontal disease have a role in its aetiology. The patient may develop signs and symptoms including pain from exposed dentine, root caries and aesthetic concerns. Management of gingival recession requires thorough patient assessment, identification of aetiological factors, and recording and monitoring of the extent and severity of the condition. Treatment should be directed at prevention of further progression and the control of symptoms and disease. The patient's aesthetic concerns should be appreciated. Surgical treatment of recession may be indicated to cover exposed root surfaces. Many surgical techniques have been described with varied reported clinical effectiveness. CONCLUSIONS: Gingival recession should be thoroughly assessed and evaluated in order to offer the most suitable management.

Locus of control beliefs predicting oral and diabetes health behavior and health status.

Our study evaluates the correlation between dental and diabetes locus of control beliefs and the potentiality of locus of control beliefs in predicting oral health behavior, dental status, diabetes compliance, and HbA1c level by using situation-specific locus of control scales and considering the value dimension. Data were collected by means of a quantitative questionnaire, a clinical oral examination and patient records. The research population comprised 149 insulin-dependent diabetics who had teeth of their own. Variables were the frequencies of tooth brushing and dental visiting, oral indexes, diabetes adherence, and HbA1c level. Dental and diabetes locus of control beliefs correlated with each other. Dental locus of control associated with frequency of dental visiting, plaque index, decayed surfaces, and with root caries, but diabetes locus of control associated only weakly with adherence with diabetes self-care regimens and not at all with HbA1c level. Correlations between dental locus of control and oral indexes were stronger among those having high value for dental care. Although there were correlations between dental and diabetes locus of control beliefs, only dental locus of control beliefs are practicable for determining health behavior and health status. It is therefore concluded that locus of control beliefs are health behavior specific.

Geriatric oral health issues in Australia.

AIM: To identify and discuss geriatric oral health issues in Australia. METHODS: A discussion of the demographic trends, oral health trends, and barriers to dental care for older Australians is presented, together with a review of Australian public and private sector geriatric dental services, geriatric dental research, and geriatric dental education. CONCLUSIONS: Key geriatric oral health issues for Australia include: edentulism is decreasing and older Australians are retaining more natural teeth; coronal and root caries are significant problems, especially as older adults become more functionally dependent, cognitively impaired, and medically compromised; the oral health status of institutionalised older Australians is poor; the onset of severe oral diseases appears to occur in many older Australians prior to their institutionalisation, when they are homebound and dependent upon carers; carers of older adults do not have access to practical education about dental care; the majority of older Australians are eligible to use public-funded dental services, but barriers limit their access to these services; few Australian public or private dental services are designed with a geriatric focus; geriatric dental education does not have a high profile in Australian dental schools; no specialty exists in Australia for geriatric dentistry, nor is there a national geriatric dentistry association.

Type 1 diabetes mellitus and oral health: assessment of tooth loss and edentulism.

OBJECTIVE: The oral health of an adult population previously diagnosed with juvenile onset insulin dependent-diabetes was comprehensively assessed. The goal of this exploratory cross-sectional evaluation was to described the characteristics related to partial tooth loss edentulism in subjects with Type 1 diabetes mellitus. METHODS: An adult population of 406 Type 1 diabetes mellitus subjects, who had been monitored for 6-8 years as part of a University of Pittsburgh longitudinal study of medical complications associated with diabetes, received an oral health examination for missing teeth, edentulism, coronal and root caries, periodontal status, and oral health behaviors. RESULTS: Of the 406 subjects evaluated, 204 had no missing teeth, 186 had partial tooth loss (1-27 missing teeth), and 16 were edentulous. Patients who had partial tooth loss or who were edentulous were generally older; had lower incomes and levels of education; and had higher rates of nephropathy, neuropathy, retinopathy, and peripheral vascular disease. A logistic regression model found partial tooth loss to be significantly associated with extensive periodontal disease in remaining teeth (OR = 7.35), a duration of diabetes longer than 24 years (OR = 5.32), not using dental floss (OR = 2.37), diabetic neuropathy (OR = 2.29), household income less than $20,000 (OR = 2.21), multiple coronal caries and fillings (OR = 1.98), and bleeding on probing (OR = 1.82). CONCLUSIONS: Although the majority of these adult Type 1 diabetes patients had serious medical complications associated with their diabetes, the possible impact of diabetes mellitus on oral health should be included in their overall management.

A 5-year follow-up study on the prosthetic rehabilitation of the elderly in Helsinki, Finland.

In 1990, 364 elderly (76-86 years) inhabitants of Helsinki, Finland, attended a dental and oral examination study that was conducted as part of the Helsinki Aging Study. In spring 1996, these subjects were recalled for a 5-year follow-up. Between the baseline and follow-up examinations, 114 (31%) subjects had deceased (86 women and 28 men), whereas 134 had either moved, were too ill, or refused to participate in the follow-up. Follow-up examination was conducted for 113 subjects (79 women and 34 men), with the participating rate being 46%. Five subjects became edentulous during the follow-up. Of the subjects, 61% had 1-32 teeth at follow-up. In these subjects, the mean number of teeth decreased from 14.9 (+/-8.3) to 13.5 (+/-8.6) (P < 0.0001). Prosthetic status changed in 40% of the elderly dentate people: 25% received new prostheses whereas 15% lost prostheses that were not replaced. New fixed partial dentures were made in five maxillae and in nine mandibles during the follow-up. Acrylic removable partial dentures (ARPD) were most frequently used: 35% of dentate subjects had an ARPD. Subjects with removable prostheses had higher levels of salivary microbes and higher root caries incidence than those with natural teeth. Furthermore, the presence of removable prostheses at baseline, together with the male gender, was clearly associated with tooth loss during follow-up. This study indicates that fixed rather than removable prostheses should be used in elderly patients. The need for a removable denture ought to be carefully considered.

The evolving impact of aging America on dental practice.

American dentistry has recognized for a quarter century that the growth in the proportion of elderly in the population is impacting on the profession. Multiple articles in the professional literature have speculated on the ways in which this change will be manifested. Data and projections from earlier articles are revisited and five trends are offered to guide professionals as they position their practices for the coming years. The increase in number and proportion of elderly in dental practices stems from successes in preventing and controlling infectious diseases during the last century. The trend has not peaked but will continue for at least two more decades. Retention of teeth into advanced age has resulted from emerging and improved preventive and restorative dental advances directed at children and adults beginning mid-century, and dental utilization studies confirm the elderly are seeking dental care at an unprecedented and growing rate. Chronic disease and infirmity that accompany advanced age make dental care more challenging for this group. Dentists and their staff will need to continuously undertake educational opportunities that will foster and maintain their facility in providing care to the elderly. They will need to do this because Americans of advanced age are becoming the dominant age group seeking, and able to pay for, sophisticated dental services. The blend of those services is shifting away from removable prostheses to a rising demand for restorative, periodontic, and endodontic care. Root caries, in particular, will be a growing challenge to both providers and patients. There is mounting evidence oral disease impacts endocrine, cardiovascular, and pulmonary health, particularly in frail elders, and will likely provide many elderly additional stimuli to seek dental care. Providers who seek an alternative approach for delivering their services will find growing demand for and satisfaction with traveling to patients, rather than the other way around.

Effects of hyposalivatory medications on saliva flow rates and dental caries in adults aged 65 and older.

Institutionalized adults aged 65 or older often receive medications that have been associated with decreased saliva flow. Flow rates depressed by hyposalivatory medications are thought to increase susceptibility to dental caries. In this study, a cross-sectional comparison was made of stimulated whole saliva rates and coronal and root caries prevalence in a group of older adults, in a long-term care facility, taking hyposalivatory medications vs. a control group. No significant differences were found between the two groups in masticatory or gustatory stimulated flow rates or in mean decayed coronal or root surfaces.

A resin-modified glass ionomer restorative: three-year clinical results.

Resin modified glass ionomer (RMGI) restorative materials have gained popularity in recent years. Their use is most often indicated in Class III and Class V cavities in adults and in numerous applications in children. This popularity in use has taken place in the absence of scientific knowledge of the RMGI materials. Lacking are adequate clinical trials to validate the proposed indications. The purpose of this study was to examine a representative RMGI in cervical abrasions and root caries in adults. Patients were recalled up to three years to evaluate standard clinical criteria. Results found the RMGI to be inferior to conventional composite resin in similar applications. The most noted deficiencies were in color stability and anatomic form, or wear of the RMGI. The results of this prospective clinical trial would suggest a limited longevity for RMGI compared to traditional restorative materials. This study also reinforces the need for evidence of clinical performance prior to making decisions regarding material selections.

Three-year coronal caries incidence and risk factors in North Carolina elderly.

The data presented in this paper are from the Piedmont 65+ Dental Study (1988-1991), designed to assess the levels of coronal and root caries, periodontal disease, tooth loss, and a variety of dental health-related needs among a representative sample of 234 black and 218 white noninstitutionalized older adults in North Carolina. Of the 452 subjects followed for 3 years, 45% of blacks and 59% of the whites developed new coronal caries when caries was defined as decayed and filled surfaces, decayed root fragments, and crowned surface (p = 0.022). The annualized rate of caries increment for blacks and whites was 0.8 and 1.6 surfaces per 100 at risk (p < 0.001), respectively. The mean 3-year net increment per subject, excluding newly crowned surfaces, was 1.6 and 2.1 (p = 0.025), respectively. Whites had more newly filled and crowned surfaces, whereas blacks had more newly decayed surfaces and more decayed root fragments. Logistic regression models using baseline explanatory variables showed factors related to coronal caries differed between blacks and whites. For blacks, having more teeth, higher concentration of lactobacilli in stimulated saliva, more decayed and filled root surfaces, and smoking were related to the development of new coronal DFS (mostly D). For whites, having more coronal surfaces at risk and having more physical health problems but not seeking medical care in the past 6 months were related to the development of new coronal DFS (mostly F). The study showed the caries attack rate to be higher for whites than blacks, mainly as a result of more crown restorations, whereas blacks appeared to be at greater risk for incident lesions. Thus, in order to obtain more realistic figures for caries risk groups, coronal caries increment can and should be presented including and excluding crowns, since the utilization of dental services is likely to differ between groups of older adults.

Resin-modified glass ionomer cement and self-cured resin composite luted ceramic inlays. A 5-year clinical evaluation.

OBJECTIVE: This study evaluated IPS Empress ceramic inlays luted with two chemical-cured luting agents, a resin-modified glass ionomer cement (Fuji Plus (F)) and a resin composite (RC) (Panavia 21 (P)). METHODS: Seventy-nine ceramic inlays were placed in Class II cavities in 29 patients. At least two inlays were placed in each patient to compare the luting techniques intra-individually. In each patient half of the inlays were luted with F and the other half with P. The inlays were evaluated clinically, according to modified USPHS criteria (van Dijken, 1986), at baseline, after 6 months, and yearly during 5 years. RESULTS: At 5 years, 71 inlays were evaluated. Two small partial fractures were observed at 3 years (1P, 1F). One inlay showed recurrent root caries at 4 years (P). Four inlays, two in each group showed non-acceptable color match (2P, 2F). Small defects were observed in 4 inlays (2P, 2F). A slight ditching of the cement margins was observed in both luting groups but did not seem to increase during the second half of the evaluation. No significant difference in durability was observed between the two luting agents. SIGNIFICANCE: IPS Empress inlays luted with the chemical-cured RC and the resin-modified glass ionomer cement functioned satisfactory during the 5 years follow-up.

Oral disease in the elderly in long-term hospital care.

OBJECTIVE: To obtain baseline information on the prevalence of oral problems and disease in institutionalized elderly in a Scottish hospital. DESIGN: A cross-sectional clinical investigation with complementary microbiological studies as appropriate. SUBJECTS AND METHODS: A cohort of 147 elderly in five long-term care wards; collection of demographic data; clinical examination to determine: i) the dental and denture status and associated lesions such as Candida-associated denture stomatitis and angular cheilitis, ii) oral mucosal disease; swabs as appropriate for microbiology. MAIN OUTCOME MEASURES: Dental status, root caries prevalence; denture status and hygiene, and associated disease; oral mucosal health. RESULTS: Median period of institutionalization of 147 patients was 15 months and 65% were aged 80 years or more; the majority were significantly mentally impaired; 52% wore complete dentures, 9% were partially dentate, 19% possessed partial or incomplete dentures; 20% were neither dentate nor had dentures. Of 80 patients who verbalised their complaints, 35% complained of dry mouth and 45% had denture-related problems, principally discomfort. The commonest oral finding was a coated tongue (56%); angular cheilitis was present in 25%, and Candida-associated denture stomatitis in 19%; none had oral ulcers. CONCLUSIONS: There was considerable unmet dental need with significant oral disease and poor levels of oral and denture hygiene in this target group; both dental and medical professionals should act in concert to deliver curative as well as preventative dental care for the elderly living in institutions to improve their quality of life.

Dental caries and related factors in 88- and 92-year-olds. Cross-sectional and longitudinal comparisons.

Our aim was to compare two groups of 88- and 92-year-olds (n = 92 and n = 40), respectively, with regard to teeth, caries, and salivary and microbial conditions. Oral variables were analyzed in relation to functional capacity and use of cardiovascular agents and psychoactive drugs. Untreated root caries, plaque score, and counts of lactobacilli increased between the ages of 88 and 92 years (P < 0.01). Nine of the 24 longitudinally followed up subjects had lost 1-5 teeth over 4 years, and 17 subjects had developed new caries (DFS). The mean caries increment over 4 years was 1.3 coronal and 3.6 root surfaces, and new DFS per 100 surfaces at risk was 4.3 coronal and 17.5 root surfaces. Plaque score and final pH of buffer capacity increased (P < 0.05 and 0.01, respectively), whereas saliva flow, independent of gender, was unchanged. Use of cardiovascular agents and psychoactive drugs was associated with a deteriorated dental status.

Host-derived proteinases and degradation of dentine collagen in situ.

Dentine root caries is a process of demineralization and degradation of the organic matrix by proteinases. In this in situ study, the presence and activity of the matrix metalloproteinases 1, 2 and 9 (MMP-1, MMP-2, MMP-9) in saliva and in completely demineralized dentine specimens were investigated. Furthermore, the activity of cathepsin B was determined in saliva. A correlation between these enzymes and the level of degraded collagen was investigated. Demineralized dentine specimens were mounted in the partial prosthesis of 17 volunteers. Saliva samples were taken at 0, 2 and 4 weeks. After 4 weeks, the enzymes were extracted from the dentine specimens and the collagen loss was assessed. The collagen loss varied between 0 and 40.3%. Zymography of the saliva and the dentine extract samples showed that (pro-)MMP-2 and (pro-)MMP-9 were present. The levels of active MMPs were assessed, using fluorogenic MMP-specific substrates. All but 3 of the 51 saliva samples showed MMP-1 activity ranging from 1.5 to 101.1 relative fluorescence units (RFU)/s. Forty-eight saliva samples showed gelatinolytic MMP-2/MMP-9 activity (1.7-141.1 RFU/s). MMP-1 activity was shown in all dentine extracts varying between 3.5 and 295.0 RFU/s. From the dentine extracts, 15 showed MMP-2/MMP-9 activity (0.2-13.7 RFU/s). The MMP activity from both saliva and dentine extracts did not correlate with the collagen loss. The activity of salivary cathepsin B varied from 4.8 to 42.2 arbitrary units/min. A positive correlation was found between salivary MMP activity and cathepsin B activity. This study revealed that gelatinolytic enzyme activity was present both in saliva and dentine collagen. No correlation could be observed, however, between the level of enzyme activity and the collagen loss of the dentine specimens.

Plaque pH and microflora of dental plaque on sound and carious root surfaces.

Given the hypothesis that root caries is the result of acid formation by acidogenic micro-organisms, the present study was performed to relate sucrose-induced pH response of dental plaque on root surfaces to the microbial composition of the overlying plaque. Seventeen caries-active elderly Chinese with poor oral hygiene and with both sound and carious root surfaces were examined. Plaque pH was measured before and up to one hour after a controlled sucrose mouthrinse. Plaque samples for microbiologic analyses were collected from 2 sound and 2 or 3 carious pH-measurement sites in each subject. The prevalence of the following micro-organisms was assessed as % of total viable counts on Brucella agar: Prevotella intermedia, Prevotella melaninogenica, Fusobacterium nucleatum, Campylobacter rectus, Capnocytophaga spp., Actinomyces viscosus, Actinomyces naeslundi, Streptococcus spp., S. sanguis, S. mitis, S. mutans, S. sobrinus, Lactobacillus spp., and Candida spp. There was no difference in plaque pH response on sound and carious root surfaces. The plaque pH response was more pronounced in the maxilla than in the mandible for both sound and carious sites. There was no difference in microbial composition of dental plaque on sound and carious root surfaces. The pH response to sucrose was the same regardless of the presence or absence of mutans streptococci. Our results thus do not readily support the traditional concept of caries formation.

Dental abnormalities in children treated for neuroblastoma.

PURPOSE: To determine the frequency and types of dental abnormalities among children treated at a young age for cancer, as represented by neuroblastoma. PATIENTS AND METHODS: We retrospectively reviewed the dental records and panoramic radiographs of 542 children who were treated for neuroblastoma at our institution over a 31-year period. Patients in our study had to meet the following criteria: they were treated on an institutional protocol, they had undergone panoramic radiography, and their dental follow-up continued for at least 2 years after diagnosis. We evaluated the frequency of clinically or radiographically apparent microdontia, excessive caries, root stunting, hypodontia, and enamel hypoplasia in our study population. RESULTS: Of the 52 patients who met the study criteria, 71% developed dental abnormalities, comprising microdontia in 38%, excessive caries in 29%, root stunting in 17%, hypodontia in 17%, and enamel hypoplasia in 17%. In nearly half (23) of our patients, neuroblastoma was diagnosed on or before their first birthday. CONCLUSION: Children treated for neuroblastoma are at high risk for abnormal dental development. The abnormalities in these patients may require extensive dental care and can compromise their quality of life. Frequent dental examinations and an intense oral hygiene program before, during, and after treatment may improve overall dental health.

Artificial caries around restorations in roots.

An artificial caries technique was used to produce caries-like lesions in the cavity walls adjacent to microfilled resin restorations with and without dentin bonding agent, and glass-ionomer cement restorations, in the roots of extracted teeth. The lesions had histological characteristics similar to those of natural lesions and to those of the lesions produced by other experimental methods. The zonal pattern of the lesions was examined by means of polarized light microscopy and microradiography, and the depth of the lesions was measured for assessment of the microleakage around the restorations. Three cavity cleaning regimes-water spray alone, 50% citric acid, and a proprietary cleaner-were compared in conjunction with the three restorative methods. Cavity cleaning with the citric acid or the proprietary cleaner, and the use of a fluoride-releasing restorative material, acted to reduce the depths of the lesions. Glass-ionomer cement restorations in cavities cleaned with citric acid showed lesions significantly shallower than those treated with other restorations. The glass-ionomer cement was soluble in the acidic environment but promoted the precipitation of minerals in the lesions. The use of a dentin bonding agent did not affect the depth of demineralization around the microfilled resin restorations.

The effect of a fluoridated dentifrice on root and coronal caries in an older adult population.

Little information is available on the effect of fluorides on root surface caries in adults. This double-blind clinical study of 810 healthy adults, aged 54 and older, demonstrated decided cariostatic effects of a fluoridated dentifrice containing 1,100 ppm F as sodium fluoride. Statistically significant differences on both coronal (41%) and root surface caries (67%) incidence were produced in the test group and compared with a control dentifrice group during 1 year of study.

Oral health among institutionalised elderly in Zagreb, Croatia.

OBJECTIVE: A survey of dental health status was conducted in the institutionalised elderly in Zagreb, Croatia in order to assess the dental and oral health of the elderly population. PARTICIPANTS: In 139 institutionalised elderly from a single nursing home in Zagreb, dental and oral status was registered according to World Health Organization criteria. There were 108 (77.7%) female and 31 (22.3%) male subjects aged 58-99 years. RESULTS: The results showed that 45.3% of the interviewed persons were totally edentulous in both jaws. A significant increase in prevalence of edentulousness with the increasing age was recorded. The mean decayed, missing and filled teeth number was 27. The average number of teeth with caries was 1.03 per person, the number of the teeth extracted was 6.9 per person and teeth with fillings 0.74 per person. The average number of teeth with root caries was 0.17. Approximately 9 teeth per person were in need of treatment. Filled teeth were found 25.9% of subjects and decayed teeth in 30.9%. The mean number of remaining sound teeth, decayed teeth and residual roots in the elderly decreased with increasing age. Complete periodontal treatment was required in 5.8% of the participants and no significant differences between genders in periodontal status could be noticed. CONCLUSION: The results of this study suggest poor dental health in this group of the institutionalised elderly and the necessity of improving and implementing some special features in the dental health services programs for the institutionalised elderly.
