Evaluating The Relationship Between Blood Magnesium And DMFT Levels In The Operating Room Of The Faculty Of Dentistry, Isfahan University Of Medical Sciences

Abstract

Introduction: Magnesium is the fourth most abundant cation in the body and the second cation inside the cells.
The possibility of dental decay in individuals with different levels of magnesium in the blood varies. Thus, the
present study evaluates the relationship between the level of magnesium in the blood and DMFT in the
operating room of Isfahan University of Medical Sciences.
Materials and Methods: This descriptive, analytical, and cross-sectional study evaluated 90 patients who were
referred to the operating room of the Isfahan Faculty of Dentistry. Before entering the operating room, the
patients completed a checklist including information on age, sex, education level, weight, height, and physical
condition based on the ASA and DMFT classification of the patient. Then, they were transferred to the
operating room. Before general anesthesia and during venipuncture, the patient's blood sample was taken from
the angioket by the primary executor of the project. After the start of anesthesia and in the examination done
at the beginning of the dental work, The DMFT of the patients was calculated and recorded by the student of
the project based on the number of extracted, filled, and decayed teeth. Then, the data were analyzed in Spss
26 Software at an error level of 0.05 in two descriptive and inferential levels.
Results: Ninety patients who were referred to the operating room with a minimum age of 18 years and a
maximum of 26 years with a mean age of 21.60 years participated in this study. The mean total magnesium in
the examined subjects was 1.87, the highest magnesium in the healthy group was 1.93, and the lowest
magnesium in the disabled group was 1.83. The mean total calcium in the studied population was 8.70 and the
highest level of calcium was observed in the healthy group, and the lowest level was observed in the disabled
group. Moreover, the highest DMFT was observed in the systemic group (11.50) and the lowest DMFT was
observed in the healthy group (8.16). An inverse significant correlation was observed between the level of
DMFT and the level of magnesium in the studied patients.
Conclusion: level of blood magnesium is associated with dental caries, so decreasing the magnesium level
increases the probability of dental caries.
