This cross-sectional study aims to examine the effect of marijuana-smoking on dental caries experience and to explore the potential combined effects of tobacco and marijuana cigarette-smoking.
We used data from the 2011-2014 National Health and Nutrition Examination Survey (NHANES). We examined demographics, tobacco- and marijuana-smoking, dental examination, and dietary intake. Caries was measured as decayed, missing, filled teeth (DMFT). Data analysis included univariate, bivariate analyses, and linear regression model (LRM) to examine the association between marijuana-smoking and DMFT.
Mean DMFT score was lowest for nonsmokers (8.72) and highest for current marijuana smokers (9.87) (P < .0001); however, LRM results revealed that marijuana-smoking was not associated with caries. Adjusted DMFT was the highest for current tobacco and former marijuana smokers (β estimate = 1.18; 95% CI, -0.27 to 2.62), but the relationship was not statistically significant.
After controlling for potential confounders, there was no significant association between marijuana-smoking and dental caries experience. However, when marijuana and tobacco were smoked concurrently, there was a notable increase in DMFT, although the difference was not statistically significant. Future research should be directed towards exploring the effects of different forms of marijuana consumption, such as edibles and drinkables, on caries development. Health promotion programmes should be aimed at educating the public regarding the combined health impacts of smoking both marijuana and tobacco, considering the potential heightened caries risk.
本横断面研究旨在探讨吸食大麻对龋齿发生的影响，并探讨烟草和大麻卷烟共同吸烟的潜在影响。
我们使用了 2011-2014 年全国健康与营养调查（NHANES）的数据。我们检查了人口统计学、烟草和大麻吸烟、牙齿检查和饮食摄入情况。龋齿用龋齿、缺失、填充的牙齿（DMFT）来衡量。数据分析包括单变量、双变量分析和线性回归模型（LRM），以检验大麻吸烟与 DMFT 之间的关联。
DMFT 评分的平均值在不吸烟者中最低（8.72），在当前大麻吸烟者中最高（9.87）（P<0.0001）；然而，LRM 结果显示，大麻吸烟与龋齿无关。当前吸烟和曾经吸烟的大麻烟民的调整后 DMFT 最高（β估计值=1.18；95%置信区间，-0.27 至 2.62），但关系无统计学意义。
在控制了潜在的混杂因素后，大麻吸烟与龋齿发生之间没有显著关联。然而，当大麻和烟草同时吸烟时，DMFT 显著增加，尽管差异无统计学意义。未来的研究应该针对探索不同形式的大麻消费，如食用和饮用，对龋齿发展的影响。健康促进计划应旨在教育公众了解同时吸烟大麻和烟草对健康的综合影响，考虑到潜在的更高龋齿风险。
