“…6 Several chromophores, such as melanin and hemoglobin, are present in periodontal tissue. 15,16 In this study, the diode laser employed to image periodontal tissue has a wavelength of 532 nm. Several chromophores in biological tissues absorb light effectively at these wavelengths, including melanin and hemoglobin, which have absorption coefficients of 750 cm -1 and 230 cm -1 respectively.…”

Introduction: After caries, periodontal tissue inflammation (periodontitis) is the most common oral health problem. Photoacoustic imaging (PAI) is a new technique that uses simple components such as a diode laser and a condenser microphone. This study aimed to evaluate the performance of a simple PAI system in periodontal disease imaging by using an animal model. Methods: Normal periodontal and periodontitis tissues were obtained from Sprague–Dawley rats categorized as the 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: Results revealed that the optimal frequency of laser modulation for periodontal tissue imaging was 19 kHz with a duty cycle of 50%. The photoacoustic (PA) intensity of periodontal tissues was −68.71 dB for treatment group 3, −70.34 dB for treatment group 2, −71.69 dB for treatment group 1, and −73.07 dB for the control group. PA image analysis showed that the PA intensity from periodontal disease groups was higher than the control group. Conclusion: This study indicates the feasibility of using a simple PAI system to differentiate normal periodontal tissues from periodontitis tissues.

“…Er, laser gave the shortest time before the recurrence of gingival pigmentation. Taher Agha & Polenik (2020) reported that both diode and Erbium lasers were fast, proficient in removing the pigmentations and well accepted by the patients [18]. The aesthetic outcomes were certainly encouraging, and the patients were extremely satisfied.…”

The pigmentation of oral soft tissues is predominantly an aesthetic problem because lifestyle, media, and social influences impact people's perception of beauty, which in turn affects their self-esteem as well as their relationships. The melanin pigmentation of the gingiva has become a real concern in the Gulf region, especially for younger people and females, who seek aesthetic solutions to remove the pigmentation. The pigmentation caused by melanin can be removed by surgical blades, diamond burs, chemicals, and lasers, among other methods. A systematic literature review from 2012 to 2022 was performed using databases such as PubMed, Medline, and Sciencedirect. The keywords used were "Diode laser", "Erbium laser", and "Melanin pigmentation". PRISMA flowchart was used to describe the selection process of searched articles. Findings revealed that 6 out of 8 studies listed superior characteristics and treatment outcomes of diode lasers as compared to Erbium lasers. It can be concluded that the diode laser is the better option to treat gingival melanin pigmentation as compared to the Erbium lasers.

“…A clinical study that compared different wavelengths has found that melanin pigments effectively absorb the diode laser energy, enhance faster peeling, and cause no relapse as compared to an erbium laser. [31]. Although no specific mode for depigmentation is available in the system, it showed that this procedure could be performed safely with the dual-wavelength diode laser.…”

Introduction. A diode laser is one of the universally compact accepted laser systems used fundamentally for soft tissue applications. Most diode laser devices have a single wavelength of either 810 nm for superior coagulation or 980 nm for tissue ablation. In these case series, the use of dual wavelengths (810 nm and 980 nm) in combination with super pulsing has provided a cleaner cut (no charring) with faster healing that eases the placement of the final restoration in the esthetic zone. Case Description. The present case series describe four cases in the esthetic zone that achieved hemostasis ablation without collateral damage to enhance gingival balance of definitive restoration. The gingivoplasty and gingivectomy modes are used to achieve efficient tissue ablation. Although there is no specific mode indicated in the FDA laser requirement for gingival depigmentation, the procedure could be safely performed with the dual-wavelength diode laser Result. All four patients revealed a good esthetic outcome and reported no pain postoperatively. Healing was uneventful, and definitive restoration was delivered within two to four weeks postoperatively. Conclusion. Within the limitation of these case series, the dual-wavelength super pulsed diode laser has the capacity to deliver peak powers resulting in efficient cutting and less tissue charring and also as an alternative tool for removal of gingival pigmentation. Prospective clinical research with larger sample size is needed for conclusive results.
