About

Snuff use and smoking associated with poor periodontal health, especially if used together.

Full description

Aim: The investigators investigated how snuff use and smoking affect periodontal health parameters and mortality in a Swedish cohort, hypothesizing that snuff use increases the risks.

Material and methods: Study cohort of 1 532 subjects aged 30 to 40 (758 men and 774 women) from Stockholm area was clinically examined and followed up from 1985 to 2015. Associations were analysed between periodontal health parameters, snuff use, smoking and age of death. For analyses, all subjects were classified into four groups: "dual-users" (current and ex-snuffers, current and ex-smokers); "pure snuffers" (current and ex-snuffers); "pure smokers" (non-snuffers, current and ex-smokers) and "non-users" (non-snuffers and non-smokers). Cross-tabulation, chi-square and Fisher's exact tests were used.

Inclusion criteria

In 1985-1986 a sample was selected from the registry file of all inhabitants of the Stockholm area, of people born on the 20th of any month from 1945 to 1954.The sample comprised 3200 people. They were informed about the purpose of the study and called for clinical investigation. 1681 (52.5%) individuals, 840 men and 841 women, participated in the study. From the remaining 1519 non-respondents to the initial call, 100 randomly selected subjects, 45 men and 55 women, were reinformed and persuaded and finally agreed to participate in this investigation. They were used as a drop-out control sample.
