| Summary: | The aim of this paper was to evaluate marginal bone loss (MBL) and bone density (BD) in the alveolar bone surrounding
the titanium implants with or without ultraviolet (UV) pre-treatment at different wavelengths in vivo. Randomized
control trial conducted at the CMH Lahore Medical College, Institute of Dentistry. This interventional study enrolled
patients undergoing replacement of missing teeth. Sixty-six Dio UFII implants with hybrid sandblasted and acidetched
(SLA) surface treatments were divided equally into three groups. Control Group A was not irradiated, while implants
in groups B and C were irradiated with UVA (382 nm, 25 mWcm2) and UVC (260 nm, 15 mWcm2), respectively. MBL
and BD in the surrounding bone were evaluated at day 0 (baseline) and 8th and 26th week. SPSS 20.0 was used for
data analysis. Repeated measure ANOVA followed by One-way ANOVA, Tukey’s test and Paired t-test were used for
comparison. p ≤ 0.05 was considered statistically significant. Both UVA and UVC treated groups showed minimal
MBL compared to control group, with no significant difference between the two experimental groups. Meanwhile, there
was a steady increase in BD in all groups over time, with UVC showing a significant improvement between the 8th
and 26th week. MBL was reduced and BD was increased in both UV treated groups. However, UVC irradiation has the
potential to control MBL and produce denser bone in SLA coated implants. |
