Summary
Piezocision-assisted orthodontics did not significantly alter pulp volume changes compared to conventional treatment during tooth retraction. Pulp volume decreased in both groups, with no clear link to root resorption.
Area of Science:
- Dentistry
- Orthodontics
- Periodontics
Background:
- Orthodontic treatment can lead to root resorption and decreased pulp volume.
- Piezocision-assisted orthodontics is a minimally invasive technique to shorten treatment duration.
Purpose of the Study:
- To compare pulp volume changes in maxillary anterior teeth after en-masse retraction with or without piezocision-assisted orthodontics.
Main Methods:
- Prospective randomized clinical trial involving 23 patients undergoing maxillary anterior tooth retraction.
- Patients were divided into piezocision-assisted or conventional groups.
- Pulp volume and root length changes were measured using 3D software.
Main Results:
- Pulp volume significantly decreased in all anterior teeth in both groups.
- No statistically significant difference in pulp volume decrease was observed between the groups.
- A moderate correlation was found between pulp volume change and root length in the right canine only.
Conclusions:
- Piezocision-assisted orthodontic tooth movement has a comparable effect on pulp volume to conventional treatment.
- Pulp volume changes do not appear to be related to the extent of root resorption.
