Snuff Use, Smoking, Periodontal Health and Premature Death: 30-year Study

Periodontitis Clinical Trial

Official title:
Snuff Use, Smoking, Periodontal Health and Premature Death: 30-year Study

Clinical Trial Summary

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

Clinical Trial 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. ;
