Background:
Implant failure may necessitate another surgical procedure to improve implant survival. Photofunctionalization(PF) with UV light is a promising method to enhance dental implant osseointegration. The study evaluates the effect of the PF on bone quality around the implants using Fractal Dimension Analysis (FDA).
Methods:
A total of 42 implants were placed in a split-mouth design and evaluated using FDA on panoramic radiographs taken pre- and post-operatively. Regions of interest (25 × 25 pixels) were analyzed using ImageJ. Statistical analysis used SPSS 26 with a 95% confidence level. Shapiro-Wilk test confirmed non-normal distribution.
Results:
A statistically significant increase in Fractal dimension(FD) values was observed in the test group between pre- and post-operative images (p = 0.044). The control group showed a non-significant increase (p = 0.794).
Conclusions:
PF appears to enhance osseointegration by improving bone microstructure as shown by increased FD values. FDA is a reliable imaging-based proxy for evaluating implant-related bone changes.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
