Latar Belakang : Morfologi oklusal yang sangat kompleks dan celah gigi yang bervariatif menjadi

penyebab awal terjadinya karies. Pit dan Fissure sealant sebagai upaya pencegahan karies dalam

kedokteran gigi preventif, selama ini banyak digunakan klinisi dalam upaya mempromosikan kesehatan

gigi. Bahan sealant yang sering digunakan adalah Resin dan Glass Ionomer Cement, kedua sifat Resin

dan Glass Ionomer Cement terdapat pada bahan Compomer sealant. Kebocoran mikro pada Compomer

dipengaruhi oleh besar perbedaan koefisien ekspansi termal Compomer dan gigi disebabkan oleh

perubahan suhu yang mempengaruhi retensi bahan pada gigi.

Metode : Penelitian eksperimental laboratorium menggunakan 32 sampel gigi premolar pasca ekstraksi

yang dilakukan fissure sealant dengan Compomer (grup 1) dan Resin Bis-GMA (grup 2). Gigi yang telah

di fissure sealant disimpan dalam saliva buatan selama 24 jam pada suhu 37ºC dalam inkubator.

Thermocycling dilakukan pada suhu 6ºC dan 60ºC selama 250 putaran dengan jarak 30 detik. Gigi diolesi

varnish kuku dan direndam dalam methylene blue 5% selama 4 jam. Gigi dicuci lalu dibelah dengan arah

bukopalatal menggunakan bur separating disk dan kebocoran mikro diuji dengan mikroskop digital

dengan perbesaran 100x. Data yang diperoleh dianalisis dengan uji statistik Mann-Whitney.

Hasil : Rerata skor penetrasi pada Compomer sebesar 13,94 .00 dan Resin bis-GMA sebesar 19.06. Hal

tersebut menunjukkan bahwa kebocoran mikro pada Compomer lebih kecil dibandingkan Resin bis-

GMA. Uji statistik Mann-Whitney menunjukan nilai sig. sebesar 0,096 (p>0,05).

Simpulan : Tidak terdapat perbedaan yang signifikan antara kebocoran mikro Compomer dan Resin bis-

GMA dan rerata kebocoran mikro Compomer lebih kecil dibandingkan Resin bis-GMA

Kata Kunci : Resin bis-GMA, Compomer, pit dan fissure sealant, kebocoran mikro.

Abstrac

Introduction : A very complex occlusal morphology and varying tooth gaps are the initial cause caries

dental. Pit and Fissure Sealant as an effort to prevent dental caries in preventive dentistry has been used

by clinician all this time to promote dental health. The sealant’s materials often used are Resin and Glass

Ionomer Cement. Compomer is a sealant material which combines two characteristics of Resin and Glass

Ionomer Cement. Microleakage on Compomer is influenced by the large differences in thermal

expomeration coefficients of Compomer and teeth. It is obtained that still there is microleakage which

relates to the temperature changing which affects the dental material’s retention. This research aims to

understand the micro leakage of Compomer and Resin bi-GMA sealant materials on temperature

changing as sealant material.

Methods: The type of research used was the experimental study. Samples were divided into two groups,

namely group 1 (Compomer), and group 2 (Resin bis-GMA). There were four steps in doing this research,

which were applying each fissure sealant material then the tooth was stored in artificial saliva for 24

hours at 37ºC in incubator, and then performing the thermocycling at 6⁰C and 60⁰C for 250 rounds

spaced 30 seconds. After that, the teeth were smeared with varnish nails and soaked in 5% methylene blue

for four hours. The last, the teeth were washed and splited in a buccopalatal direction, and the

microleakage was tested with a digital microscope. The Mann-Whitney test showed that sig. value 0.096

(p>0,05).

Result: the result of this research shows that there is no significant difference of micro leakage score

between Compomer and Resin bis-GMA sealant. The compomer sealant has less micro leakage score

than resin bis-GMA did.
