Background and Aim:Dental caries is the most
common cause of tooth loss and early detection of dental caries is a major
steptowards dental health.Carious lesions is a fundamental step in
preserving dental health. Tooth decay could change tooth electrical
conductivity. The
porosity of the enamel tissue as well as the electrical conductivity of teeth
can be altered by tooth decay. Therefore, the aim of this study was to measure
the electrical resistance of teeth and its relation to the degree of dental
caries.
Materials
and Methods: In this experimental study to
investigate the structural differences in dental caries, electrical parameters
such as resistance and capacitance of teeth were measured for sound enamel and
dentin, superficial caries, deep caries, and extensive caries. The resistance
and capacitance of teeth with various degrees of decay were compared with sound
teeth. The relationship between the electrical parameters and the decay rate
was evaluated using ANOVA Test.
Results:The
results showed that theelectrical
resistances changed significantly by decay (p<0.05) By increasing the depth
of tooth decay, the electrical resistance decreased based on a linear
relationship. It also revealed there was a significant association between
capacitance and deep and superficial decay. (P=0.01) The capacitance and decay
changed based on a non-linear relationship.
Conclusion:
Quantification of dental resistance can be a useful tool for detection of
caries, and it is proposed as a method for detecting deep caries with high
accuracy.
