Solubility of zinc oxide-eugenol and calcium hydroxide cements in simulated dentinal fluid

The solubility of four dental cement bases was measured in simulated dentinal fluid and distilled water to evaluate the relevancy of the American Dental Association solubility test for cement bases in contact with vital dentine. A simulated dentinal fluid was formulated utilizing glucose, distilled water, and sterile human plasma. Cement-base samples were immersed in either distilled water or simulated dentinal fluid at 37°C in a shaker water-bath for 1, 2, or 3 months. Weight loss values were compared utilizing a three-way analysis of variance. Zinc oxide-eugenol cements were significantly more soluble in simulated dentinal fluid than distilled water, while the calcium hydroxide cement bases were significantly more soluble in distilled water than simulated dentinal fluid.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73127/1/j.1365-2842.1989.tb01365.x.pd

Periodontal health status of people with dementia – A systematic review of case-control studies

Background: The number of older people increases globally, so is the risk of cognitive impairment. Periodontal diseases are common among older adults with significant tooth loss and periodontal problems. Thus, this review explored the periodontal disease conditions among individuals with and without dementia. Methods: Available databases such as Medline/Pubmed, Web of Science, Scopus, Cochrane Library and Embase/OVID were used in the search. Case-control studies reporting on periodontal disease and dementia parameters were selected based on PICO (Population, Intervention, Comparison and Outcomes) framework. A Newcastle-Ottawa Scale (NOS) was used to assess the quality reporting of the studies and PRISMA guideline was used for screening. Results: A total of ten studies were identified for analysis. Most studies reported higher plaque index score (PI), bleeding on probing (BoP), pocket depth (PD) and clinical attachment loss (CAL) among individuals diagnosed with dementia or Alzheimer’s disease compared with clinically healthy controls or individual diagnosed without dementia. A higher prevalence of subjects with severe periodontal disease was also observed in individuals diagnosed with dementia/Alzheimer’s disease. The quality of the studies was found to be moderate with lower comparability and ascertainment criteria scores. Conclusion: This qualitative analysis has shown poor periodontal health and increased inflammatory mediators in case groups compared to the control groups. Thus, more quality studies and novel intervention are warranted to reduce the impact of periodontal health on dementia globally

Impact of periodontal disease on the quality of life of older people in Indonesia: A qualitative study

Introduction: the impact of periodontal disease on oral health–related quality of life (OHRQoL) has often been investigated from a quantitative research perspective, which is based on clinical findings and an OHRQoL questionnaire. Very few studies have examined the issue from the view of qualitative research. To our knowledge, there have been no previous qualitative studies focusing the effect of periodontal disease on OHRQoL in Indonesian older people.Objectives: to explore and understand the impact of periodontal disease on the OHRQoL of older people as a subjective reflection in relation to periodontal disease experiences.Methods: semi-structured interviews were conducted in a sample of 31 older people with generalized chronic periodontitis. Thematic analysis was used to identify the key issues in participants’ accounts. The analysis was undertaken by 2 independent coders to ensure reliability. To achieve thematic saturation, successive interviews were undertaken until 5 sequential interviews did not bring new themes.Results: participants reported the negative effects likely related to periodontal disease. The impacts of periodontal disease were described by these older people as affecting more than pain, physical discomfort, and physical function restrictions. Periodontal disease also affected their psychological and social aspects of daily living. In addition, this study identified themes related to individual and environmental factors that may modify and personalize periodontal disease experiences. Furthermore, this study identified a misleading belief that problems related to periodontal disease were a normal part of aging, which might influence individuals’ expectations toward oral health. Relatedly, participants frequently reported that the progression of tooth mobility to tooth loss was an inevitable part of the aging process.Conclusions: periodontal disease negatively affected participants’ OHRQoL. It is fundamental to understand older people’s perceptions toward their periodontal disease as well as individual and environmental factors that may have an influence on their periodontal disease experiences.Knowledge Transfer Statement:This study is a reflection of Indonesian older people’s subjective periodontal disease experiences. Therefore, the present study can be used to understand older people’s perceptions, attitudes, behaviors, and experiences toward periodontal disease and how this disease may affect their quality of life. This study also highlights a widespread and misleading belief that oral problems related to periodontal disease are an inevitable part of aging in this study population

Nutrition Counseling Increases Fruit and Vegetable Intake in the Edentulous

Edentulous denture-wearers eat fewer fruits and vegetables than do comparable dentate individuals. Improved chewing ability with new dentures has resulted in little dietary improvement, suggesting that dietary intervention is necessary. The objective of this randomized controlled trial was to have a positive impact upon dietary behavior of patients receiving replacement complete dentures through a tailored dietary intervention. Readiness to change diet (Stage of Change), intake of fruits, vegetables, and nutrients, and chewing ability were assessed pre-and 6 weeks post-intervention. The intervention group (n = 30) received two dietary counseling sessions; the control group (n = 28) received current standard care. Perceived chewing ability significantly increased in both groups. There was significantly more movement from pre-action into action Stages of Change in the intervention group, who had a greater increase in fruit/vegetable consumption (+209 g/d) than did the control group (+26 g/d) (P = 0.001). Tailored dietary intervention contemporaneous with replacement dentures can positively change dietary behavior

Perceived Chewing Ability and Intake of Fruit and Vegetables

Edentulous individuals have reduced chewing ability and lower fruit and vegetable consumption compared with dentate individuals. It has been suggested that the two are causally related. However, psychosocial factors such as attitude, self-identity, and knowledge of recommendations are predictive of intake in non-edentulous persons. The aims of this study were to: determine if perceived chewing ability was predictive of fruit and vegetable intake; explore the predictive ability of knowledge, attitude, and self-identity; and compare intake between edentulous and dentate individuals. Full denture-wearing (N = 79) and dentate persons (N = 52) completed a three-day food diary. Perceived chewing ability, sociodemographic, and psychosocial factors were assessed via self-administered questionnaire. The dentate persons consumed significantly more fruit and vegetables, but differences were not significant when juices were excluded. Perceived chewing ability explained ~ 4% variance in intake. Attitude, self-identity, and knowledge explained a further ~ 20%. If the diet of denture-wearers is to be improved, psychosocial factors, as well as perceived chewing ability, must be addressed

Periodontal disease and oral health–related quality of life in the older population in Indonesia

Introduction: despite being acknowledged as the second global burden of oral disease, periodontal disease has few epidemiologic studies in the literature, particularly for developing countries. Many previous studies have assessed the relationship between periodontal disease and oral health–related quality of life (OHRQoL), with patients attending dental clinic or hospitals rather than a general population. This study attempted to fill the knowledge gap in limited information about periodontal disease and OHRQoL, with reference to a general population in a developing country. Objectives: to investigate the relationship between OHRQoL and periodontal diseases in an older population in Indonesia. Methods: we invited 582 older people from community health centers. The 369 (63.4%) older people who agreed to participate consented to an oral health examination and a questionnaire capturing demographic, socioeconomic, behavioral, and Oral Health Impact Profile–14 (OHIP-14) data. Results: almost 75% of the older people had generalized periodontitis; 3% had healthy periodontal status; and around 22% had localized periodontitis. There was a lack of statistical evidence for an association between periodontal disease status and OHRQoL. This result was based on the appraisal of the prevalence of the impact (Odds ratio [OR], 0.95 [95% CI, 0.54 to 1.59]; P = 0.77), difference in mean severities (0.07 [95% CI, –1.66 to 1.80]; P = 0.94), and extent of the impact (P = 0.996). However, we found evidence for a relationship between tooth mobility and OHRQoL for all of the OHIP assessments, including prevalence of the impact (OR, 1.87 [95% CI, 1.16 to 3.01]; P = 0.009), difference in mean severities (–2.98 [95% CI, –4.50 to –1.45]; P < 0.001), and extent of the impact (P = 0.001). Conclusion: there was a lack of statistical evidence for a relationship between periodontal disease status and OHRQoL in this society. However, we found evidence that tooth mobility, as a sign of periodontal disease progression, is related to OHRQoL. Knowledge Transfer Statement: the present study can be used by dentists, community health workers, and policy makers in Indonesia to understand the prevalence, severity, and extent of the negative impacts of periodontal disease on older people’s quality of life. In addition, this study provides information about factors that might considerably affect the oral health–related quality of life in this society, such as brushing habits, dental visit, family income, DMF-T status, and subjective appraisal toward dental health
