CIGARETTE SMOKING AND PERIODONTAL DISEASE

Cigarette Smoking and Periodontal Disease

Cigarette Smoking and Periodontal Disease among 32 Year-Olds

Introduction

A cohort study represents a group of subjects kept under observation or monitored from their birth. The cohort groups share the common properties, characteristics, or features. This is classified for the study purpose in case of a specific perspective such as cigarette smoking and periodontal disease among 32-year-olds. The cohort group comprises of a population either examined as a whole or distinct subgroups are accounted for comparison. Therefore, cohort group is a method examining the subjects after the exposure or administration of certain substance under investigation. The expenses are significantly high to conduct a cohort study. This is due to the fact that it is a longitudinal observation of an individual which consumes a long time to follow-up and generates useful data. The data is collected at regular intervals. The cigarette smoking and periodontal disease prospective cohort study are considered to yield reliable results in observational epidemiology (Persson, 2003). However, the researchers' capacity to stay in touch with all members of the cohort determines the value of a cohort study.

Discussion

The prospective study regarding the periodontal disease and cigarette smoking among the people of age 32 aims to quantify the link between cigarette smoking patterns and attachment loss. It was conducted among people born during particular year. This aims to quantify the association between periodontal attachment loss by age 32 and cigarette smoking patterns. Periodontal examinations were conducted at various age gaps. Those who had never smoked had significantly fewer ratios for the periodontal attachment loss as compared to long-term smokers.

Prospective Study Of A Representative Birth Cohort

The prospective study of a representative birth cohort can be defined as the study of subjects kept under observation or monitored from their birth after the exposure or administration of certain substance under investigation. This is the case for determining the cigarette smoking and development of disease related to periodontitis. This study aims to quantify the association between periodontal attachment loss by age 32 and cigarette smoking patterns.

Case Definition For Periodontitis

The correlation between the periodontal disease and cigarette smoking is depicted in this case study. The periodontitis prevalence was determined by identifying individuals with significant attachment loss. The attachment loss refers to the destruction of periodontal tissue caused by periodontitis. The periodontal examinations which took place for the attachment loss were conducted at ages 26 and 32. However, the information gathered at ages 15, 18, 21, 26 and 32 respectively assists in the longitudinal categorization of smoking exposure.

Measuring Smoking Exposure

The case study proposes the measurement of smoking exposure through distinctive level of questioning from various age groups. The rate of smoking was asked proportionally to the age factor of the subgroup in cohort population. The number of pack-years exposure was computed on the basis of the number of cigarettes smoked at different ages.

Logistic Regression Analysis

Logistic regression modeling was used to examine periodontitis prevalence and smoking ...
