Abstract
BACKGROUND:
The
combined orthodontic regenerative therapy approach can greatly enhance
periodontal conditions and dentofacial aesthetics in many situations.
The purpose of this study was to evaluate the effectiveness of 940nm
low-level diode laser biostimulation in enhancement of intrabony wound
healing with combined orthodontic/regenerative therapy in chronic
periodontitis subjects suffering from malocclusion.
METHODS:
Fifteen
chronic periodontitis adult patients with at least two intrabony
defects and requiring orthodontic treatment for abnormalities in
occlusion were included. A total of 30 defects were divided into two
groups and treated in a split mouth design. The defects were treated
with combined orthodontic regenerative therapy with laser irradiation
(Group I: test group) or with combined orthodontic regenerative therapy
alone (Group II: control group). The following hard and soft tissue
measurements were recorded at baseline (prior to surgery) and after six
and nine months postoperatively: probing depth (PD), clinical attachment
level (CAL) by periodontal calibrated probe and bone density (BD) using
the DBS-Win software.
RESULTS:
Probing depth reduction
was 64.57%±9.37 and 64.95%±10.07 with no statistically significant
difference between Group I and Group II. Percent change in clinical
attachment level gain were 59.77%±12.107and 38.83%±7.56 in Group I and
II respectively, with a statistically signifi cant difference (P-value
=0.005considered signifi cant). Moreover, defects treated with combined
orthodontic regenerative therapy with laser irradiation showed signifi
cant preservation of bone density with a percent decrease of 4.14%±3.17
at the end of the study period.
CONCLUSION:
Improvements
in clinical and radiographic parameters were observed following the
adjunctive use of low-level diode laser therapy and orthodontic
regenerative therapy for the management of intrabony defects in chronic
periodontitis patients.
