| 主な結果/Results |
2019年11月~2021年4月の間、24名(40歯)が本研究に組み込まれ、20名(33歯)が塗布4週後に評価された。両群ともに有意なエアー痛の減少を認めた。しかし両群間で有意差は認めなかった。 |
From November 2019 to April 2021, 24 participants with 40 teeth were enrolled in this study and 33 teeth in
20 participants were assessed at 4 weeks after treatment. A significant reduction of pain in response to air stimuli was
observed in both groups; however, no significant difference was observed between the groups. |

| 参加者背景/Baseline Characteristics |
象牙質知覚過敏が主訴の患者 |
participants who presented with a complaint of cervical dentine hypersensitivity |
| 参加者の流れ/Participant flow |
術者が計40歯を封筒法にてランダムに実験群と対照群の2群に1:1で割り付け,実験群ではケアダインシールドを塗布し,対照群ではナノシールを塗布した.術前および塗布4週間後に,評価者が再度患部に対してエアーによる誘発痛, GIおよびPIの評価を行った. |
Forty CDH teeth which matched the eligibility criteria were randomly allocated to two groups in a 1:1 ratio: the CAREDYNE Shield group (intervention group) and the Nanoseal group (control group). The pain intensity in response to air stimuli, gingival condition, and oral hygiene status of CDH teeth were assessed before and at 4 weeks after treatment. |
| 有害事象/Adverse events |
有害事象は認めなかった。 |
no harm was observed for any participant in this study. |
| 評価項目/Outcome measures |
主要評価項目は、ベースラインから術後4週目におけるエアー痛の減少量 |
The primary outcome was the reduction of pain intensity in response to air stimuli from baseline to 4 weeks after intervention. |
