歯・歯肉・舌の画像上の即時変化に関する報告が「Lasers in Surgery and Medicine」に掲載されました
ASLMS 2026（米国レーザー医学外科学会）で口演発表した、歯・歯肉・舌の反応に関する臨床報告の抄録が、同学会の公式学術誌「Lasers in Surgery and Medicine（LSM）」のASLMS 2026 Abstracts特別号に掲載されました。
本報告では、過酸化物不使用の高出力パルス青色LED照射と接触冷却を組み合わせた施術を受けた20症例について、施術前後の口腔内写真と蛍光画像を用い、歯・歯肉・舌に見られる即時変化を記録しました。
歯の表面の明るさに加え、歯肉の表面や辺縁の見え方、舌乳頭構造の視認性などに変化が観察されました。一部の症例では、拡大観察による毛細血管の視認性も記録しています。
これらは画像上の見え方に関する観察であり、組織構造の変化、血流の増加、機能の改善を直接示すものではありません。また、撮影条件や表面の水分状態などが視認性に影響する可能性があります。
日常診療で認められた複数の口腔組織の反応を探索的にまとめた報告であり、今後は撮影・評価方法を整え、観察所見の再現性と意味を検討していく必要があります。

Clinical Observations of Immediate Changes in Tooth, Gingival, and Tongue Images Published in Lasers in Surgery and Medicine
The abstract entitled “Immediate Tooth, Gingival, and Tongue Responses to Non-Thermal High-Power Blue LED Whitening: A Contact-Cooled 20-Case Study,” authored by Emi Hirano and presented orally at ASLMS 2026, has been published in the ASLMS 2026 Abstracts supplement of Lasers in Surgery and Medicine (LSM), the official journal of the American Society for Laser Medicine and Surgery.
This observational series documented immediate changes in 20 patients undergoing a procedure combining peroxide-free high-power pulsed blue LED irradiation with contact cooling. Intraoral photographs and fluorescence images were used to record findings before and after treatment.
The observations included changes in tooth-surface brightness, the appearance of gingival surfaces and margins, and the visibility of lingual papillary structures. Capillary visibility was also documented using magnified imaging in a subset of patients.
These findings concern image-based visibility and appearance. They do not directly demonstrate structural tissue changes, increased blood flow, or improved function. Imaging conditions and surface moisture may also influence visibility.
The report presents an exploratory description of responses observed across several oral tissues in routine clinical practice. Further studies using standardized imaging and assessment methods are needed to evaluate the reproducibility and significance of these observations.
