Table 3. Mean values, standard deviations and p-values of all measured parameters.
The data of left and right hemimandibles were statistically similar and were therefore pooled. The p-values presented are the results of the statistical hypothesis tests conducted to determine if the parameter data of the three minipig age groups differ significantly from each other.
