Background
Orthodontic treatment has some undesirable side effects, such as root resorption and a decrease in the size of the pulp tissue which are relatively associated with the duration of the orthodontic treatment. Piezocision-assisted tooth movement was introduced as a minimally invasive surgical procedure with an aim to shorten orthodontic treatment time. This prospective randomized clinical trial was aimed to compare the pulp volume changes of maxillary anterior teeth after en-masse retraction with or without piezocision-assisted orthodontics.
Methods
Patients who required orthodontic treatment with bilateral maxillary first premolar extractions and en-masse retraction were recruited. Patients were randomly divided into extraction with piezocision, or only extraction, serving as controls. Pulp volume and root length changes of the maxillary six anterior teeth were measured and compared between the two groups using a 3-Dimensional analytical software. Paired and independent sample t-tests were used to compare within and between groups. Bivariate correlation was done between the mean change in pulp volume and its corresponding root length. The significance level was set at α = 0.05.
Results
A total of 23 patients were included, 12 in the piezocision, and 11 in the control group. At the end of the en-masse retraction phase (mean = 122.74 ±3.06 days) pulp volume was significantly decreased in all six anterior teeth in both groups ( P < 0.01). The decrease in pulp volume was not statistically different between both groups, ( P > 0.05). There was a statistically significant but moderate correlation only between the pulp volume change of the right canine and its root length, r = 0.44, P = 0.034.
Conclusions
The effect of piezocision-assisted orthodontic tooth movement on the pulp volume was comparable to the conventional orthodontic treatment. The degree of change in pulp volume does not appear to be related to the amount of root resorption.
Trial registration: NCT03180151.
