Association between Obesity and Dental Caries in Adults: An Analysis of WHR, and DMFT Score.
Article in Obesity facts, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionThe relationship between obesity and dental caries in adults presents inconsistent findings in current literature, which necessitates further research to clarify this relationship. This study aimed to examine the association between obesity and dental caries in adults using a nationally representative sample.
methodsThis study employed data of US adults aged >20 years from the National Health and Nutrition Examination Survey (NHANES) pre-pandemic cycle. Obesity was defined using the waist-to-hip ratio (WHR), body mass index (BMI), and waist circumference. Dental caries were assessed using the Decayed, Missing, Filled Teeth (DMFT) scores.
resultsMost participants were categorized as individuals with obesity based on the WHR (74.5%) or BMI (72.7%). A significant difference in the DMFT scores and missing teeth was observed between individuals with normal weight and individuals with obesity. After adjusting for the sociodemographic variables, individuals with obesity had a 0.11 higher DMFT score (95% confidence interval [CI]: -0.01 to 0.23). A significant association was observed between the WHR and DMFT scores when age was excluded from the model, demonstrating a higher coefficient of 0.17 (95% CI: 0.05-0.30).
conclusionsA positive association was observed between obesity and dental caries in the US adult population. However, age was found to be a confounding factor in this relationship. This study highlights the relationship between oral and general health, advocating healthcare providers for an integrated health promotion strategy, through comprehensive campaigns addressing obesity, diet, lifestyle, and dental health, aiming for raising awareness and a more effective public health strategy.
