Background/Objectives: Unhealthy dietary behaviors and suboptimal oral hygiene practices remain common among Italian children, potentially affecting both nutritional and oral health. Dental caries, a preventable yet highly prevalent condition in pediatric populations, has a multifactorial etiology in which lifestyle factors play a key role. This study aimed to assess the prevalence of dental caries, dietary habits, and oral hygiene behaviors in school-aged children in Lombardy, and to identify factors associated with prevalent caries status. Methods: A cross-sectional study was conducted on 307 schoolchildren aged 9–10 years from ten schools in Northern Italy. Oral health status was evaluated through the plaque index and the DMFT/dmft index during school-based dental examinations. Dietary habits, lifestyle, and oral hygiene practices were collected through structured questionnaires. A mixed-effects logistic regression model was developed to explore potential associations between variables and prevalent caries status. Results: The dietary patterns, weight status, oral hygiene behaviors, and oral health conditions were generally consistent with the national data. Higher plaque index, skipping breakfast, consuming mid-morning snacks, and parental reports of previous caries experiences were retained in the final model. Internal validation suggested reasonable discriminatory ability overall, whereas calibration shows heterogeneity across schools. Conclusions: The findings highlight suboptimal dietary and oral hygiene behaviors among Lombardy schoolchildren and confirm their association with dental caries. Lifestyle-related factors, particularly oral hygiene practices and eating patterns, showed a relevant association with prevalent caries status in the analyzed sample. These results underscore the need for targeted preventive strategies integrating nutritional education and oral health promotion in pediatric populations.
