| Abstract | : | After caries, periodontal tissue inflammation (periodontitis) is the most common oral health problem in Indonesia. Photoacoustic imaging (PAI) is a new technique that uses simple components such as a diode laser and a condenser microphone. This study aims to evaluate the performance of a simple PAI system in periodontal disease imaging by using an animal model. Normal periodontal and periodontitis tissues were obtained from Sprague–Dawley rats categorized as control group, treatment group 1 (7 days of periodontitis induction), treatment group 2 (11 days of periodontitis induction), and treatment group 3 (14 days of periodontitis induction). The PAI system was controlled by Labview and Arduino IDE software from a personal computer. Results revealed that the optimal frequency of laser modulation for periodontal tissue imaging was 19 kHz with duty cycle of 50%. The photoacoustic (PA) intensity of periodontal tissues was −68,71 dB for treatment group 3, −70,69 dB for treatment group 2, −71,69 dB for treatment group 1, and ¬−73,07 dB for control group. PA image analysis showed that the PA intensity was higher for the samples than for non-biological materials and for the periodontal disease groups than for other groups. This study indicates the feasibility of using a simple PAI system to differentiate normal periodontal tissues from periodontitis tissues. |
