Dental health of community-living older people attending secondary healthcare: a cross-sectional comparison between those with and without diagnosed mental illness.

BACKGROUND: Mental illness and cognitive impairment are risk factors for poor dental health. METHODS: We conducted a cross-sectional study to compare the dental health of older patients attending out-patient clinics and day hospitals of old age psychiatry services (the psychiatry group, n = 103) with those attending general/geriatric medical services (the medical group; n = 99). Those living in care homes, and those with diagnosed mental illness (in the medical group) were excluded. A registered mental health nurse assessed mental and general health using validated and previously published instruments. A registered dentist made an independent assessment of dental health (examination to assess oral pathology, status of remaining teeth, and dentures) and made an overall judgment about whether the patient needed any dental treatment (a "normative" need). RESULTS: The normative need for dental treatment was significantly higher among the psychiatry group compared to the medical group (85% vs 52%; p<0.001); even after taking account of the effect of age, gender, teeth status, physical comorbidity, cognition, depressive symptoms, and overall mental and social health [adjusted odds ratio, OR (95% confidence interval): 4.32 (2.09, 8.91)]. The presence of any natural remaining teeth [OR: 4.44 (2.10, 9.42)] and Barthel Index [OR: 0.96 (0.93, 0.99)] were the two other independent predictors of the need for treatment. CONCLUSION: Dental problems are common in community-living older people, especially those with some natural remaining teeth and those with mental illness. There is a need to develop integrated mental health and dental care services for older people with emphasis on prevention of dental problems.

A survey of dentists' practice in the restoration of the shortened dental arch.

OBJECTIVES: The aim of this survey was to determine how a sample of dentists working in general dental practice in the UK sought to restore the mouths of patients who had shortened dental arches (SDAs). STUDY DESIGN: A survey was conducted over a period of six months on four commercial dental laboratories. Cases of SDAs comprising the anterior teeth and 2 to 4 premolars were examined; dental prescriptions were scrutinized and a special data collection form was completed accordingly. RESULTS: A total of 140 SDA cases were examined. Most of these cases were for mandibular SDAs (88.6%). Of the recorded SDA cases, 67.2% were restored by cobalt-chromium based removable partial dentures (RPD); 25.7% were extended by acrylic-resin based RPDs; implants were provided to restore 8 SDA cases (5.7%); and only two SDA cases (1.4%) were extended by cantilevered fixed bridges. Neither the gender of the patient ([Chi (2)= 4.19, p>0.05) nor the length of the SDA ([Chi (2) = 6.51, p>0.05) influenced the choice of prosthesis to be implemented. CONCLUSIONS: It would appear from the results of this survey that among the different restorative treatment options for SDA, the RPD was the most popular treatment option for dentists surveyed in this UK study. Extending the SDA by either an implant-supported prosthesis or cantilevered fixed bridges did not appear to be a popular choice of treatment.
