Oral impact on daily performance: need and use of dental prostheses among Brazilian adults.

Although there is a large amount of evidence that demonstrates the relationship between oral health status and oral impact daily performance, there are few studies that have evaluated the impact of prosthetic status, particularly the need for a dental prosthesis. Therefore, the aim of this study was to investigate the relationship between need and use of dental prostheses and the prevalence of oral impact on daily performance. A sample of 720 subjects, aged between 50 and 74 years, was evaluated using a cross-sectional study. Participants were selected through a multistage proportional random sampling. The impact of oral health status on daily performance (oral impact on daily performance--OIDP) and socio-demographic data was assessed using a standardised questionnaire, and clinical data were assessed by oral examination. The outcome was the prevalence of impact. The association between the explanatory variables and the outcome was analysed through two models of multivariate Poisson regression. In the adjusted model, the variables need of upper and lower prosthesis and use of lower prosthesis maintained a statistically significant association. No statistically relevant relation between socio-demographic variables and outcomes was found. Findings show that the need and use and of a prosthesis are related to oral health quality of life.

Comparison of the Glidescope, the McGrath, the Airtraq and the Macintosh laryngoscopes in simulated difficult airways*.

SUMMARY: Several indirect laryngoscopes have recently been developed, but relatively few have been formally compared. In this study we evaluated the efficacy and the usability of the Macintosh, the Glidescope, the McGrath and the Airtraq laryngoscopes. Sixty anaesthesia providers (20 staff, 20 residents, and 20 nurses) were enrolled into this study. The volunteers intubated the trachea of a Laerdal SimMan manikin in three simulated difficult airway scenarios. In all scenarios, indirect laryngoscopes provided better laryngeal exposure than the Macintosh blade and appeared to produce less dental trauma. In the most difficult scenario (tongue oedema), the Macintosh blade was associated with a high rate of failure and prolonged intubation times whereas indirect laryngoscopes improved intubation time and rarely failed. Indirect laryngoscopes were judged easier to use than the Macintosh. Differences existed between indirect devices. The Airtraq consistently provided the most rapid intubation. Laryngeal grade views were superior with the Airtraq and McGrath than with the Glidescope.

How do routines of daily activities and flexibility of daily activities affect tooth-cleaning behavior?

OBJECTIVES: The aims of this study were: (1) to investigate the level of routines and flexibility of people's daily activity and to identify how tooth cleaning fits into these activities; and (2) to evaluate the impact of different levels of routines and flexibility in daily living on pattern (frequency of tooth cleaning), structure (range of items used in tooth cleaning), performance (relative effectiveness of tooth cleaning) and the outcome of performance (gingival bleeding on probing) in tooth cleaning. METHODS: A convenience sample of 471 Brazilians aged 24 to 44 years was selected from factories, offices, banks, shops, and hospitals. Behavioral, socioeconomic, and clinical data were collected through structured interviews. Dental plaque and gingival bleeding were assessed by clinical examination. Data were analyzed by means of logistic regression. RESULTS: A highly significant relationship was observed between routines of daily activities and tooth-cleaning pattern (OR = 2.3; 95% CI = 1.34, 3.92) after adjusting for age, sex, marital status, and socioeconomic status. No significant associations were observed between routines of daily activities and gingival bleeding. A significant association was observed between tooth-cleaning frequency (OR = 1.6; 95% CI = 1.07, 2.49), performance (OR = 2.7; 95% CI = 1.77, 4.14), outcome (OR = 2.3; 95% CI = 1.31, 3.18), and flexibility of daily activities. Those who had more flexibility of daily activities had lower gingival bleeding scores. CONCLUSION: People who have a less routinized and more flexible day have higher tooth-cleaning frequency than those who have a less flexible and more routinized day. In this study, those with a more flexible day also cleaned their teeth more effectively than those who had a less flexible day, and had reduced gingival bleeding.

[Oral hygiene habits among Brazilian adults in an urban area of southern Brazil]. / Hábitos de higiene bucal de adultos porto-alegrenses.

AIMS: This study sought to analyse the oral hygiene habits (toothbrushing frequency, use of toothpick and dental floss), of a group of Brazilian adults, in relation to socio-demographic variables. The level of dental plaque and number of teeth with gums bleeding after probing were also investigated. METHODOLOGY: The sample was composed of 234 women and 237 men, from two socioeconomic status. The age range was from 24 to 44 years. Data was collected through structured interviews and clinical examinations. RESULTS: Daily toothbrushing was frequent. The median and mode were three, and it was associated with sex and socio-economic status. The majority of the sample population (67.5%), reported using dental floss and its use was associated with sex and socio-economic status. The use of toothpicks was frequent: 54.6% of the study group used them, and their use was also associated with sex, age and social class. The majority of the sample population had a moderate level of dental plaque (62.6%). The level of dental plaque was associated with social class. A quarter of the subjects did not have teeth with gums bleeding after probing. Bleeding gums were associated with age and social class. CONCLUSION: Oral hygiene habits were considered good for most of the participants of the study. However, improvements, are necessary among men and members of low social class.

The relationship between tooth cleaning behaviour and flexibility of working time schedule.

This study tested whether there is a relationship between levels of flexibility of working time schedule and the pattern (frequency of tooth cleaning), structure (range of items used in tooth cleaning), and performance (relative effectiveness of tooth cleaning measured by levels of dental plaque) of tooth cleaning. 471 Brazilian workers from both sexes aged 24 to 44 years were selected from factories, offices, banks, shops and hospitals. Behavioural, socio-economic and clinical data were collected through structured interviews and clinical examination. Data analysis included frequency distribution and simple and multiple logistic regression. The response rate was 92.5%. Simple logistic regression showed there was a highly statistically significant relationship between flexibility of the working time schedule and tooth cleaning frequency, the range of oral hygiene aids used and the level of dental plaque. All 3 associations remained highly statistically significant after adjusting for age, sex, socio-economic status and marital status. Socio-economic status was statistically significantly associated with tooth cleaning frequency, the use of oral hygiene aids and the level of dental plaque. It was concluded that high flexibility of working time schedule is related to pattern, structure and performance of tooth cleaning.
