The toothbrush: a rare but potentially life-threatening cause of penetrating oropharyngeal trauma in children.
(49/282)
We present the case of a 10-year-old girl with pharyngeal injury caused by a toothbrush, the snapped head of which lodged in her upper oropharyngeal wall. Initial examination of the oral cavity did not reveal bleeding, a foreign body, or a wound. Nasopharyngoscopy showed lodgment of the toothbrush piece in the upper oropharynx, pulsating in synchrony with heartbeats. Computed tomography showed the toothbrush head near the carotid artery. The foreign body was surgically removed without any intraoperative or postoperative complications. The diagnosis and management of oropharyngeal injuries by stick-like foreign bodies, such as a toothbrush or chopsticks, are discussed. (+info)
Clinical evaluation of an ionic tooth brush on oral hygiene status, gingival status, and microbial parameter.
(50/282)
It has long been recognised that the presence of dental plaque leads to gingivitis and periodontal disease, as well as dental caries. Today tooth brushing is the most widely accepted method of removing plaque. Hence this present clinical study was undertaken to evaluate the effectiveness of an ionic toothbrush on oral hygiene status. For this study, 20 dental students in the age group of 18-20 years were included. All the subjects after undergoing dental prophylaxis were then provided with ionic toothbrushes, either active (equipped with lithium battery) or inactive (without lithium battery). Plaque index and gingival bleeding index were examined at 7th, 14th, and 21st day. Microbial assessment was done for detection of colony forming units (CFU) from the plaque samples which were collected on 0 day and 21st day, both before brushing and after brushing. Results shown a significant reduction in all the parameters and the reduction was more significant in active and inactive ionic toothbrush users. It was concluded that both active and inactive ionic toothbrushes reduced the plaque index and gingival bleeding index scores significantly and active ionic tooth brushes were more effective as compared to inactive ionic toothbrushes. There was no soft tissue trauma following the use of both type of toothbrushes, which showed that ionic toothbrushes were equally safe for regular long-term use. (+info)
Toothbrush selection: a dilemma?
(51/282)
The toothbrush is a fundamental tool used for accomplishing plaque control. Various types of toothbrushes available in the market keep the buyer in a state of dilemma as to which one to choose, due to lack of information about the "quality" of it. This study has been designed to understand whether all the products available in the market adhere to the specifications laid down by the ADA, which is universally accepted in standardization of a tooth brush. 95% of the brushes surveyed contain less number of bristles per tuft than specified and a large percentage deviate from the standard prescribed value for their bristle diameter and other dimensions. Few brushes labeled as "Soft" were "Medium" and labeled "Medium" were "Hard". The study will bring to light the quality of toothbrushes available in India for a rationalised selection of appropriate toothbrush by the community at large. (+info)
The relation between family socioeconomic trajectories from childhood to adolescence and dental caries and associated oral behaviours.
(52/282)
OBJECTIVES: To investigate the influence of family socioeconomic trajectories from childhood to adolescence on dental caries and associated behaviours. DESIGN: Population-based birth cohort. SETTING: Representative sample of the population of subjects born in 1982 in Pelotas, Brazil. PARTICIPANTS: Adolescents (n = 888) aged 15 years old were dentally examined and interviewed. MAIN OUTCOME MEASURES: Dental caries index (DMFT), care index (F/DMFT), tooth brushing, flossing and pattern of dental services use. MAIN RESULTS: Adolescents who were always poor showed, in general, a worse pattern of dental caries, whereas adolescents who never were poor had a better pattern of dental caries. Adolescents who had moved from poverty in childhood to non-poverty in adolescence and those who had moved from non-poverty in childhood to poverty in adolescence had similar dental pattern to those who were always poor except for the pattern of dental services use, which was higher in the first group. In all groups girls had fewer carious teeth, better oral hygiene habits and higher dental services use than boys. CONCLUSION: Poverty in at least one stage of the lifespan has a harmful effect on dental caries, oral behaviours and dental services use. Belonging to upwardly mobile families between childhood and adolescence only contributed to improved dental care. (+info)
Covariates of tooth-brushing frequency in low-income African Americans from grades 5 to 8.
(53/282)
PURPOSE: The purpose of this study was to examine tooth-brushing frequency in 575 urban and nearby suburban African American children as part of a comprehensive risk-reduction study for students at high risk for violence, drugs, school delinquency, and unsafe sexual behaviors to determine which covariates predicted tooth-brushing frequency. METHODS: Students were surveyed 5 times, from the beginning of grade 5 and the end of each year through grade 8, and parents were surveyed at the beginning of grade 5. Peer influence, importance of being liked, self-esteem, attitudes towards tooth-brushing, oral health knowledge, self-efficacy, parental attitudes, and other covariates were examined for the ability to predict self-reporting of tooth-brushing frequency. RESULTS: In the fifth grade, peer influence, the importance of being liked, and physical self-esteem were the significant predictors, and peer influence continued to predict tooth-brushing in the eighth grade. Oral health knowledge and parental influence were not significant. CONCLUSION: Peer influence is an important factor in tooth-brushing behavior in metropolitan African American preadolescent children. (+info)
Effect of ceramic coating by aerosol deposition on abrasion resistance of a resin composite material.
(54/282)
Aerosol deposition (AD coating) is a novel technique to coat solid substances with a ceramic film. The purpose of the present study was to investigate the effect of AD coating on abrasion resistance of a resin composite material. A 5-microm-thick aluminum oxide layer was created on the polymerized resin composite. The specimen was cyclically abraded using a toothbrush abrasion simulator for 100,000 cycles. Abraded surface was then measured with a profilometer to determine the average roughness (Ra) and maximum roughness (Rmax). It was found that abrasion cycling increased the Ra value of the No-AD-coating group, but decreased the Ra and Rmax values of the AD coating group. Moreover, the AD coating group showed significantly smaller Ra and Rmax values after 100,000 abrasion cycles as compared to the No-coating control group. Microscopic observation supported these findings. In conclusion, the resistance of the resin composite against toothbrush abrasion was improved by AD coating. (+info)
Oral hygiene frequency and presence of visible biofilm in the primary dentition.
(55/282)
The purpose of this study was to associate oral hygiene frequency and presence of visible biofilm in the primary dentition. The sample consisted of 90 children, aged up to 4 years old, outpatients of the University Hospital of the Rio de Janeiro State University. The examinations were carried out in a dental office by a single trained examiner who was aided by an assistant. The parents answered a structured questionnaire about oral hygiene methods and frequency. Two biofilm indices, one simplified (BF1) and the other conventional (BF2), were used. BF1 classifies biofilm as absent, thin or thick, in anterior and/or posterior teeth, and provides a score for the patient, whereas BF2 classifies biofilm as absent or present, provides scores for three surfaces of each tooth and the final score is the percentage of tooth surfaces with biofilm. More than half of the parents (51 - 56.7%) reported they cleaned their child's teeth at least twice a day, while 7 (7.8%) had never cleaned their child's teeth. BF1 revealed that 12.2% (11) of the children had no visible biofilm, 37.8% (34) had thin biofilm in anterior and/or posterior teeth, 27.8% (25) had thick biofilm in anterior or posterior teeth and 22.2% (20) had thick biofilm in both anterior and posterior teeth. BF2 revealed a mean value of 21.8% (s.d. 16.5). No statistically significant correlations were found between oral hygiene frequency and the two biofilm indices (p > 0.05), indicating that oral hygiene frequency was not associated to oral hygiene quality in the evaluated sample.

Health literacy education for children: acceptability of a school-based program in oral health.
(56/282)
A study was conducted to examine the acceptability and effectiveness of a new type of health literacy program for children. The program was organized in the form of a workshop by a dentist. Sixty-three students aged 11-12 years were divided into 14 groups. The discussion topic was the effectiveness of toothbrushing for preventing periodontal disease. To investigate this issue, each group was asked to choose the most appropriate study design for obtaining a reliable answer. After the group discussion, the participants received a lecture on appraising the quality of health information. Pre- and post-program questionnaire surveys were administered to assess the program. Sixteen percent of the students had searched for health information via the Internet; however, 56% claimed to be interested in searching for health information via the Internet. The most approved design was a cohort study (seven groups) as the most valid type of research for showing the effectiveness of toothbrushing. The post-program questionnaire survey revealed that 89% of participants easily understood the content of the program, and 76% found the program to be useful. These findings demonstrate the feasibility of using health literacy programs for schoolchildren. Health literacy programs for children will need to be developed and administered through collaboration between education and health professionals. (J. Oral Sci. 49, 53-59, 2007). (+info)
