象牙質知覚過敏の即時変化に関する報告が、アメリカレーザー医学会公式雑誌「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、象牙質知覚過敏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、施術前から象牙質知覚過敏が認められた15症例を対象に、過酸化物不使用の高出力パルス青色LED照射と冷却管理を組み合わせた施術の前後で、エア刺激に対する痛みの変化を観察しました。
対象となった全15症例で、施術直後の痛みの数値評価尺度（Numeric Rating Scale：NRS）が施術前より低下しました。歯の外観と、併せて観察された歯肉の蛍光画像上の所見も記録しています。
本報告は対照群を設けていない症例集積であり、清掃、使用材料、光照射、冷却それぞれの寄与を分けて評価することはできません。また、直後の変化を中心とした観察であり、変化の持続期間や作用機序を明らかにしたものではありません。今後の検証につながる臨床所見として報告しました。

Clinical Observations of Immediate Changes in Dentin Hypersensitivity Published in Lasers in Surgery and Medicine
The abstract entitled “Immediate Attenuation of Dentin Hypersensitivity During High-Power, Peroxide-Free Blue LED Whitening: A Non-Thermal, Cooling-Controlled Case Series,” 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 case series examined immediate changes in air-blast-evoked pain in 15 patients with pre-existing dentin hypersensitivity following a procedure combining peroxide-free high-power pulsed blue LED irradiation with cooling control.
Post-treatment Numeric Rating Scale (NRS) scores were lower than baseline scores in all 15 patients. Tooth appearance and accompanying gingival fluorescence findings were also documented.
This uncontrolled case series cannot distinguish the individual contributions of cleaning, applied materials, light irradiation, and cooling. The observations primarily concern immediate responses and do not establish their duration or underlying mechanism. The findings were reported as clinical observations warranting further investigation.
