Population based norming of the UK oral health related quality of life measure (OHQoL-UK©)

Objectives The aims of this study were to establish normative age-gender values for the UK oral health related quality of life measure (OHQoL-UK©) in Britain and to provide a local reference for its interpretation. In addition, to identify key factors associated with oral health related quality of life in the UK.Materials and methods A national survey conducted with the assistance of the Office for National Statistics involving a random probability sample of 2,718 households. Participants were interviewed about their oral health status. The impact of oral health on quality of life was measured using the 16 item OHQoL-UK measure.Results The response rate was 68% (1,838/2,718). The majority (75%, 1,378/1,838) perceived their oral health as affecting their life quality and did so across a wide range of domains. Age-gender norm values are presented. Variations in OHQoL-UK scores were apparent in relation to socio-demographics: age (P < 0.05), social class (P < 0.01), and self-reported oral health status: number of teeth possessed (P < 0.01).Conclusions The impact of oral health on the life quality of Britons was substantial, in both positive and negative ways and associated with socio-demographic and oral health (self-reported) factors. National norm values presented should provide a reference source for meaningful interpretation of similar data and local studies.

Oral Health-Related Quality of Life in Hong Kong Preschool Children

Objectives: To assess the impact of early childhood caries (ECC) on the quality of life in a population of preschool children and their families in Hong Kong. Methods: A random sample of 1,296 Chinese preschool children participated in the survey and were subjected to an oral examination for their ECC status by 2 trained examiners. The parents were asked to respond to the Early Childhood Oral Health Impact Scale (ECOHIS) and an extra set of questions concerning their sociodemographic background. Results:The final data analysis included 1,261 children with a mean (±SD) age of 3.9 ± 0.66 years. The prevalence figures for ECC and severe ECC were 19.9 and 15.2%, respectively. Decayed teeth were found in 34.3% of the children while only 5.2% had filled teeth. The mean (±SD) dmft in this group of children was 1.5 ± 2.98. Higher ECOHIS scores were found in parents with lower education or income level, or with children who were born in mainland China (p < 0.05), or with children who had decayed, missing, or filled teeth (p < 0.001). In multiple regression analyses, decayed teeth and filled teeth in primary dentition were the better predictors (p < 0.001) of the ECOHIS score among the various parent and child characteristics collected in this survey. Conclusions: The findings of this study showed that parents of young children with dental caries experience perceived that both the children and other family members had poorer quality of life.

Silver Diamine Fluoride and Education to Prevent and Arrest Root Caries among Community-Dwelling Elders

Background/Aims: Root caries among elderly communities is of growing public health concern globally. This controlled clinical trial investigated the effectiveness of silver diamine fluoride and oral health education in preventing and arresting root caries. Methods: Two hundred sixty-six elderly subjects who had at least 5 teeth with exposed root surfaces and did not have serious life-threatening medical diseases were allocated to 3 groups according to a computer-generated random list: group 1 (the control group) received oral hygiene instructions (OHI) annually; group 2 received OHI and silver diamine fluoride (SDF) application annually, and group 3 was given OHI and SDF application annually, plus an oral health education (OHE) programme every 6 months. Results: Two hundred twenty-seven elderly subjects were followed for 24 months. The mean numbers of new root caries surfaces in groups 1, 2 and 3 were 1.33, 1.00 and 0.70, respectively (ANOVA, p < 0.05). Group 3 had fewer root surfaces with new caries than group 1 (Scheffé multiple-comparison test, p < 0.05). The mean numbers of arrested root caries surfaces in groups 1, 2 and 3 were 0.04, 0.28 and 0.33, respectively (ANOVA, p < 0.01). Group 3 and group 2 had a greater number of active root caries surfaces which became arrested than group 1 (Scheffé multiple-comparison test, p < 0.05). Conclusion: Annual application of SDF together with biannual OHE was effective in preventing new root caries and arresting root caries among community-dwelling elderly subjects.

A national study of the importance of oral health to life quality to inform scales of oral health related quality of life

Objectives: To assess the content validity of traditional oral health status scales as measures of oral health related quality of life (OHQOL), based on a general publics perception of the most important ways in which oral health affects quality of life (QoL). Methods: A nationwide United Kingdom study involving a random probability sample of 1778 adults. Data were collected by face-to-face interviews in participants homes. Results: Most 75%(1332) perceived oral health as being important to QoL. Among them, 53%(699/1332) identified oral healths importance to QoL as being in a positive manner. Existing scales predominantly fail to include this dimension. The general public ranked oral healths importance to QoL through a range of physical, social and psychological domains. Most frequently though affecting eating or comfort; domains considered by all instruments. Other domains/ways are presented. It is apparent that even when some of the multidomain scales are employed, they frequently omit items that the public perceives as being most important to QoL. Conclusion: The study raises concerns about the appropriateness of utilising many of the existing oral health status scales as measures of OHQOL because the concepts do not appear to be interchangeable.

Oral carriage of yeasts and coliforms in stroke sufferers: a prospective longitudinal study.

AIM To investigate prospectively the qualitative and quantitative changes in oral carriage of yeasts and coliforms in southern Chinese people suffering from stroke. MATERIALS AND METHODS In 56 elderly people suffering from stroke in a rehabilitation unit of a general medical hospital in Hong Kong, oral microbiological sampling using a combined imprint culture, oral rinse approach and clinical assessment was made during the acute stroke phase, on hospital discharge and 6 months later. RESULTS The oral carriage of yeasts increased significantly during acute stroke (P<0.05), whereas coliform carriage did not. A reduction in oral carriage of yeasts was found on hospital discharge and 6 months later and in coliforms at the 6-month assessment (P<0.05). Candida albicans and Klebsiella pneumoniae were the predominant yeast and coliform respectively. Stroke-related difficulty in tooth brushing and denture wearing were associated with higher oral yeast carriage (P<0.05). We also report here for the first time that the use of aspirin was associated with lower oral yeast carriage in people suffering from stroke. CONCLUSION Oral yeast carriage was closely linked to the level of stroke-related functional disability that improved over time but had not totally resolved 6 months after hospital discharge. The oral reservoir of yeasts and coliforms in people suffering from stroke is noteworthy by care providers as K. pneumoniae may cause aspiration pneumonia.

Association between Developmental Defects of Enamel and Different Concentrations of Fluoride in the Public Water Supply

Objectives: To compare the prevalence and severity of developmental defects of enamel (DDE) among subjects whose maxillary incisors developed during periods with different concentrations of fluoride in the public water supply. Methods: Standardized intra-oral photographs of random samples of 12-year-old children were collected in 1983, 1991 and 2001 (n = 1,990) in Hong Kong and assessed for DDE by a trained masked examiner. The fluoride concentrations in the public water supply at the times when the enamel on their maxillary incisors developed were 1.0, 0.7 and 0.5 ppm, respectively. Results:The mouth prevalence of DDE for these children (based on the maxillary incisors) were 92.1, 55.8 and 35.2% in the years 1983, 1991 and 2001, respectively (p < 0.001). Most of these children were affected by diffuse opacities (89.3% in 1983, 48.5% in 1991 and 32.4% in 2001, p < 0.001). Marked differences in the mean number of teeth affected by DDE (p < 0.001) and in the maximum extent of DDE (p ≦ 0.002) between 1983, 1991 and 2001 were also observed. Conclusions: A decrease in the prevalence and severity of DDE among the maxillary incisor teeth of the children corresponded to the reductions in the concentration of fluoride in the water during the time of enamel development.

Staff recruitment, development and global mobility

This paper considers issues that relate to staff recruitment, staff development and global mobility of dental academics. Published literature, which has a North American bias, is reviewed. Recommendations, which may be applicable world-wide, are made to address evident and pertinent areas of concern in terms of the availability of quality dental teaching staff in dental teaching institutions so as to sustain the global dental academic enterprise at appropriately high levels of achievement.

Oral health promotion interventions on oral reservoirs of staphylococcus aureus: a systematic review

The oral cavity serves as a reservoir of Staphylococcus aureus for infection of the lower respiratory tract and cross-infection to other patients. This systematic review was designed to examine the effectiveness of oral health promotion interventions on this pathogen. The PubMed, ISI Web of Science, and Cochrane Library databases were searched for clinical trials assessing the effect of oral health promotion interventions on oral and oropharyngeal carriage of S. aureus. Oral health promotion interventions on oral reservoirs of S. aureus in both systemically healthy and medically compromised groups consisted of oral hygiene interventions only. There was a lack of evidence pertaining to the effectiveness of mechanical oral hygiene interventions against this pathogen. Chlorhexidine delivered in oral hygiene products such as mouthrinses, gels, and sprays appeared to have some utility against S. aureus, although some studies found equivocal effects. There was a dearth of studies investigating the efficacy of other chemical agents. Although many chemical agents contained in oral hygiene products have proven in vitro activity against S. aureus, their clinical effectiveness and potential role as adjuncts or alternative therapies to conventional treatment remain to be confirmed by further high-quality randomized controlled trials.

Orofacial functional impairments among patients following stroke: a systematic review.

OBJECTIVES The objective of this study was to review orofacial functional impairments among patients following stroke, including objective and subjective assessment. METHODS A structured search strategy was applied to three electronic databases (Pubmed, Embase, and Web of Science) to identify effective papers. Relevant data regarding subjects, method, outcomes, and key findings were extracted from the effective papers and the results were summarized. RESULTS The initial search yielded 5227 papers, and 18 effective papers (Kappa: 0.971) were in accordance with the inclusion criteria. The patients with stroke consistently showed a decreased lip force, salivary flow rate, and chewing performance compared with the healthy controls. Due to equivocal results gained from the effective papers, the qualitative assessments regarding whether there was any change in masticatory force on the affected side and oral health-related quality of life were inconclusive. CONCLUSIONS Existing evidence highlights a number of compromised orofacial functions experienced by patients following stroke. These impairments appear to be sustained, with spontaneous recovery unlikely to occur. While rehabilitative approaches may have the potential to improve orofacial function and quality of life following stroke, there is currently a lack of evidence-based interventions available to inform the development of comprehensive rehabilitation protocols.

The adjunct effectiveness of diode laser gingivectomy in maintaining periodontal health during orthodontic treatment.

OBJECTIVE To evaluate the effectiveness of diode laser gingivectomy as an adjunct to nonsurgical periodontal treatment in the management of periodontal health among patients receiving fixed orthodontic appliance therapy (FOAT). MATERIALS AND METHODS Thirty patients undergoing FOAT with gingival enlargement were block randomized into two treatment groups. The test group received diode laser gingivectomy (940-nm diode laser, ezlase, Biolase Technology Inc) as an adjunct to nonsurgical periodontal treatment. The control group received nonsurgical periodontal treatment only. For both groups, five periodontal parameters were assessed at baseline, 1 month, 3 months, and 6 months: Plaque Index, Gingival Index, bleeding on probing, probing pocket depth, and Gingival Overgrowth Index. Intra- and intergroup variations in the periodontal parameters were determined over time. RESULTS Both groups showed statistically significant improvements in periodontal health over the study period (P < .05). However, significant improvements in periodontal health were evident earlier among the test group subjects (P < .05). The magnitude of improvement in periodontal health compared to baseline was greater in the test group than in the control group for Gingival Overgrowth Index at 1 month (P < .001) and 3 months (P < .05), Gingival Index at 3 months (P < .05) and 6 months (P < .05), and probing pocket depth at 1 month (P < .05). CONCLUSIONS Nonsurgical periodontal management with or without the adjunct use of lasers can be effective in the management of gingival health problems among patients receiving FOAT. The adjunctive use of lasers can produce an earlier and greater improvement in gingival health.
