The primary objective of this 6 month study is to compare the effectiveness of oral health promotion interventions on both clinical oral health, and oral opportunistic respiratory pathogens in institutionalized elders. Secondary objectives are to investigate changes in oral health-related quality of life, incidence of adverse side effects, pneumonia, as well as subject acceptability. Elders residing in nursing homes in Hong Kong will be recruited into the clinical trial. Patients will be randomly allocated into one of the following groups: 0.2% chlorhexidine spray, 0.1% pH-balanced chlorine dioxide spray, or sterile water spray (placebo control), once daily. Dental plaque, gingival bleeding, oral opportunistic respiratory pathogens, oral health-related quality of life (OHRQoL), and pneumonia incidence will be assessed at baseline, 3 months and 6 months. Subject acceptability of the interventions will be assessed at the end of the clinical trial.
Objective: To compare the efficacy of Curaprox® CS 5460 Ultra Soft and Oral-B® Indicator Plus toothbrushes in dental plaque removal. Methods: 50 adult participants will be included in the sample. For a period of 24 hours (at two different times), they will be instructed to stop oral hygiene. During the final 4 hours, the interruption of consumption of foods and liquids will be recommended, and in smokers' case, the use of cigarettes. In two clinical visits (T0 and T1), volunteers will be asked to brush their teeth for 1 minute with Curaprox® (CS 5460 Ultra Soft) e Oral-B® (Indicator Plus) toothbrushes. Disclosure will be performed prior to and after brushing and the presence of plaque on the tooth surfaces will be evaluated. Turesky Modified Quigley Hein Plaque Index will be used for the plaque record. For statistical analysis, paired t tests will be performed to compare the effectiveness of toothbrushes and correlation test to assess whether the fact that the patient was aware of the toothbrush that will be used influenced in their performance.
Objective: This study investigated how patients' knowledge, attitude, and perceptions influence their oral hygiene practices as well as peri-implant health. Materials and Methods: Participants with single implant crowns placed in 2007-2011 completed a questionnaire that examined their knowledge, attitude, and perceptions on oral hygiene practices and peri-implant health before receiving a periodontal examination, prophylaxis, and oral hygiene education. Clinical parameters recorded were peri-implant probing depths and plaque index, width of keratinized mucosa, implant crown characteristics, reason for tooth loss, and diagnosis of peri-implant health.
In today's society cosmetic dentistry plays an important role in social relationships and in important aspects of life such as job applications and recruitment processes. Currently, the only available treatment option for patients suffering from black dental pigmentation of bacterial origin is repetitive professional dental cleanings every two or three months, which involve a significant financial outlay, and have been found to be psychologically detrimental due to the lack of a perceived cure. These pigmentations are of unknown etiology, although there has been reported the presence of black-pigment producing bacteria, such as Porphyromonas gingivalis, Tannerella forsythia and Aggregatibacter actinomycetemcomitans in such black plaque. These bacteria are found in a group known as periodontopathogens, bacteria responsible for the appearance of periodontitis, an oral chronic disease with high prevalence. In this context, photodynamic therapy, which uses the application of diode light with a wavelength between 400-500 nm for the elimination of periodontal pathogenic bacteria, has demonstrated effectiveness and absence of adverse effects on the management of patients with periodontitis. The proposed study seeks to evaluate the effect of photodynamic therapy on teeth with extrinsic black pigment, in order achieve an eradication of the stains. The investigators will also proceed to analyze in depth the bacterial composition of these stains before the application of photodynamic therapy, in order to stablish the aetiological agents of this black plaque.
It is well accepted that the greatest contributor to the health of the periodontium and dentition is regular and thorough dental plaque removal, typically by means of adequate toothbrushing. Although patients are typically informed about the risks of substandard oral hygiene and the contributing factors in oral/dental disease by dental professionals, research has shown that an undesirably high proportion of adults find thorough toothbrushing with a standard manual toothbrush to achieve a plaque-free state challenging, as evidenced by high worldwide levels of gingivitis and/or periodontitis.
The aim of the present study was to evaluate the effect of a xylitol containing propolis tablet on the salivary pH, total microorganisms count and soluble and insoluble extracellular polysaccharide concentration of the dental biofilm of adolescents in a randomized controlled clinical trial. In addition, evaluate the acceptability of the individuals regarding the characteristics of the tablets (appearance, taste, aroma and texture) through a questionnaire. To that end, healthy adolescents between 10 and 19 years old, without active carious lesions, who seek care at the Pediatric Dentistry Clinic of the Universidade Federal do Rio de Janeiro (UFRJ) will be randomly assigned to the two groups of the study: control group (propolis- consumers of tablets with propolis), respecting an interval of 30 days of rest between the consumption of the tablets. The study will be cross-checked and the principal investigator will be blind. The tablets will be given to the participants on an exact number of days of use and they will be instructed to consume two tablets per day for 7 uninterrupted days. After 30 days of interval, they will consume the other type of tablet with the same recommendations of the first one. The total non-stimulated saliva collection will be performed at the beginning of the study (before the consumption of the tablets) and 7 days after the intervention of each type of tablet, as well as the collection of the dental biofilm. Saliva and biofilm samples from all individuals will be identified and later analyzed in the laboratory, on the same day of collection, to measure the salivary pH, with the aid of a phmeter, and evaluation of the growth of total microorganisms (CFU / mg biofilm ), respectively. From the biofilm collected and stored in saline, concentrations of soluble and insoluble extracellular polysaccharides will also be measured by means of a spectrophotometer. Statistical tests will be used to compare the groups, with a significance level of 5%. As results, the propolis-containing tablet is expected to increase the salivary pH and decrease the number of total microorganisms in the dental biofilm.
Oral health is an important component of general health and oral cavity acts as a mirror to the health of individuals and communities. Inadequate focus on primary prevention of oral diseases, poses a sizeable challenge for numerous countries, especially low and middle income countries. Mobile phone technology is relatively new and its successes in chronic disease is well documented but there is little evidence available in its use for improving oral health and dietary habits of children. This will be a Pilot Randomized Control Trial (RCT) . It will be conducted in public and private sector schools of Quetta city, Pakistan. Study will comprise of intervention and a control arm. Duration of intervention is 6 months. In the intervention group, study participants will be the parents. School teachers will send oral health education and reminder messages on frequent intervals to educate children's parents on oral hygiene and reinforce their behaviors to improve their child oral health. The primary school children in the control group will not receive any intervention
The purpose of this study was to use the principle of fluorescence to identify oral diseases not readily visible to the naked eye. A imaging device with a removable and modular head consisting of arrays of Light Emitting Diodes (LEDs) with differing wavelengths (405nm,450nm or white) was used to image teeth to detect fluorescent biomarkers such as porphyrins associated with poor oral health (plaque). The process utilizes illumination of the teeth and gums using a specific array of LEDs in the visible and near-visible spectrum and is non-invasive. Successful implementation of the device would provide proof-of- concept validation for its use as a safe, rapidly deployable solution to assess oral hygiene.
Background: Children with congenital heart defects (CHD) are reported to have poorer oral health compared with healthy children. The aim of the present study was to evaluate the effect of an intensive oral health care program among children with CHD followed from infancy to the age of five years, by comparing their oral health status at five years with a control group of children with CHD who had not received the program. Methods: In this longitudinal study, children in western Norway with a need for lifelong follow-up due to congenital heart defects were invited to participate (n=119). Children born in 2008-2011 were offered a promotive oral health intervention program from infancy to the age of five years. The outcome measures for evaluating the intervention were dental caries prevalence, dental erosion, plaque index and gingival bleeding index. The data of the intervention group were compared with cross sectional oral health data of five year old controls with CHD born 2005-2007 (already published).
