Objectives: BACKGROUND: It is known that different factors influence the mineralcomposition of bones. Eating behavior and harmful habits have an important impact on the health of individuals and affect their physiological processes. A high-sucrose diet affects the mineralization of all hard tissues in general through mechanisms that have not been fully explained and that are the subject of constant research. AIM: To study changes in the mineral composition of the maxillary bone caused by nutritional factors Methods: The samples (n=9) were taken by accidental detachment of bone (maxilla and/or mandible) during oral surgical procedures in the Chair of Surgery III of the School of Dentistry of the UNC (National University of Córdoba, Argentina). The signature of anInformed Consent (OdontologíaUNC-CAIS50I) was required, and an Adapted Nutritional Frequency of Consumption Questionnaire was completed to identify a high intake of sucrose. The mineral analysis was performed through an electrondetector (SEM), with a record of 5 points per sample, and the relationsCalcium/Phosphorus (Ca-P) and Calcium/Sulfur (Ca-S) were taken into account. The data obtained was statistically analyzed (CI=95%) and regression models were proposed to explain the relationship between mineral proportions and the explanatory variables considered in this study: diet, age, gender and maxilla.Results: When studying the Ca/P ratio, the factors analyzed did not show a significant effect, although patients whose diet was rich in sugar (n=3) had lower values (2.3±0.6/2.8±0.8). With respect to the Ca/S ratio, the patients who consumed more sugar showed significantly higher values than the others (77.1± 20.3/15.5± 8.7), with a p<0.01. Conclusions: A trend of increase in the Ca/S bone ratio was observed in individuals with a high consumption of sucrose.
