Interpreting Poisson Regression Models in Dental Caries Studies.

Oral epidemiology involves studying and investigating the distribution and determinants of dental-related diseases in a specified population group to inform decisions in the management of health problems. In oral epidemiology studies, the hypothesis is typically followed by a cogent study design and data collection. Appropriate statistical analysis is essential to demonstrate the scientific association between the independent factors and the target variable.

Dental Erosion and Caries Status of Chinese University Students.

Purpose: To describe the prevalence and severity of dental erosion and caries experience of Chinese university students in Hong Kong.

Materials And Methods: First-year Chinese students were invited to attend a dental clinic at a university campus in Hong Kong during their freshman orientation. A questionnaire was used to investigate the potential factors affecting their dental status, including sociodemographic factors, toothbrushing habits, dietary habits (consumption of sugary drinks), time elapsed since last dental check-up and self-perceived dental erosion status.

Oral health status of elderly chinese with dementia in Hong Kong.

Purpose: To compare toothbrushing habits, unstimulated salivary flow rates and oral health status of elderly Hong Kong Chinese with and without dementia.

Materials And Methods: A sample size calculation was performed and a sample of 82 elderly Chinese with dementia were invited who were aged 60 or above, fit for periodontal assessment with probing and attended day-care centres. Age- and gender-matched generally healthy people without dementia were recruited as controls.
