目的:
本研究の目的は,3 種類のフッ素徐放性窩裂溝封鎖材の異なる窩裂溝タイプにおける浸透性と適合性を分析することである.
AIM: This study aimed to analyze the penetrability and adaptability of three different fluoride-releasing sealants in different fissure types.
材料と方法:
ヒト小臼歯部抜去歯(=45本)を無作為に15本ずつ3群に分け、フィスシール(FS)、ヘリオシールFプラス(HS)、ボーテシーラント(BS)のシーラントを無作為に割り付けた。封鎖したサンプルを頬舌面で切開し、走査型電子顕微鏡(SEM)で最深部の亀裂を観察した。サンプルは、亀裂のタイプ(I、IK、U、V、逆Y)についても観察された。シーラントと亀裂壁の間の浸透率(POP)と全体的な隙間(OG)は、ImageJソフトウェアを用いてSEM画像から測定した。
MATERIALS AND METHODS: Extracted human premolars ( = 45) were randomly divided into three groups of 15 each and randomly allotted to receive the sealants Fisseal (FS), Helioseal F Plus (HS), and Beautisealant (BS). The sealed samples were sectioned in the buccolingual plane, and the deepest fissures were examined under a scanning electron microscope (SEM). The samples were also observed for the fissure types (I, IK, U, V, and inverted Y). The percentage of penetration (POP) and overall gap (OG) between the sealant and fissure wall were measured from the SEM images using ImageJ software.
結果:
FS群が最も高いPOP(68±29.3%)と最小のOG(1.0±0.9μm)を示した。POPが最も少なかったのはBS群であった(52.3±20.3%)。I型小窩裂溝はほとんどの歯で認められ(33%)、V型小窩裂溝は最も少なかった(18%)。平均OGはFS群で有意に少なかった(一元配置分散分析;=0.046)。平均POPはFS群で最も高く、次いでHS群、BS群であった。
RESULTS: Group FS exhibited the highest POP (68 ± 29.3%) and the smallest OG (1.0 ± 0.9 µm). The least POP was observed for group BS (52.3 ± 20.3%). The I-type fissure was seen in most of the teeth (33%), and the V-type fissure was the least (18%). The mean OG was significantly less in group FS (one-way analysis of variance; = 0.046). The mean POP was the highest in group FS, followed by groups HS and BS.
結論:
このSEM試験から、FSは亀裂への浸透性と適応性に比較的優れているのに対し、BSは最も劣る材料であることが明らかになった。
CONCLUSION: This SEM study revealed that FS had relatively superior penetrability and adaptability into the fissures, whereas BS was the least-performing material.
臨床的意義:
小窩裂溝はプラークを保持しやすいため、平滑面よりも清掃が困難でう蝕になりやすい。小窩裂溝を封鎖し、う蝕を予防するために、フィッシールは長持ちし、耐久性に優れているため、臨床的に推奨される可能性がある。この論文の引用方法Albar NH, Vinothkumar TS, Shibli WH, 異なるフッ素徐放性小窩裂溝シーラントの浸透性と適応性の比較分析:An Study.J Contemp Dent Pract 2025;26(1):55-61.
CLINICAL SIGNIFICANCE: Pits and fissures are harder to clean and more prone to dental caries than smooth surfaces because of their plaque-retentive nature. Fisseal could be clinically recommended to seal the pits and fissures and prevent dental caries, as they are long-lasting, and durable.
