Java project on periodontal diseases: the relationship between vitamin C and the severity of periodontitis
: Blackwell Synergy
Objective: To study the relationship between vitamin C and the severity of
Material and Methods: The study population consisted of subjects from the Malabar/
Purbasari tea estate on West Java, Indonesia. In 2002, clinical measurements were
performed in 128 subjects, including evaluation of plaque, bleeding on probing, pocket
depth and attachment loss. In 2005, 123 out of 128 subjects could be retrieved who
were present at the examination of 2002. Blood samples were taken to measure plasma
vitamin C levels. Information about the subjectÃ¢â‚¬â„¢s dietary habit was obtained by means
of a personal interview guided by a questionnaire.
Results: Plasma levels of vitamin C ranged from 0.02 to 34.45 mg/l with a mean of
7.90 mg/l ( 5.35). The correlation coefficient between plasma vitamin C level and
periodontal attachment loss was 0.199 (po0.05); stepwise linear regression
revealed that vitamin C levels explained 3.9% of the variance in periodontal
attachment loss. Subjects with vitamin C deficiency (14.7% of the study population)
had more attachment loss compared with those with depletion or normal plasma
vitamin C values.
Conclusion: The negative association between plasma vitamin C levels and
periodontal attachment loss suggests that vitamin C deficiency may contribute to the
severity of periodontal breakdown.
