Aim:
The aim of study to evaluate both occlusal and gingival microleakage levels of
class V cavıties prepared by using different type cavite preparation method and
by restorated with different glass ionomer cements.

Material and Methods: In this study were used molar teeth (n = 90) which were planned to for
extraction due to orthodontic or periodontal and which did not contain any
caries, restorations and cracks. Standard class V-cavities were prepared at the
buccal surface of each tooth to be 3 mm wide, 2 mm high and 1.5 mm deep. Teeth
were divided into 3 main groups (n = 30) according to cavitation preparation
method (Er:YAG laser, Er,Cr:YSGG laser and conventional method) and these
groups were divided into 3 subgroups (n = 10) according to the restorative
material. Samples were examined in stereomicroscopy at X16 magnification and
SEM. Datas were analyzed using with statistically evaluated by Kruskal-Wallis
and Wilcoxon tests at 5% significiant level.

Results: In both SEM and microscopy groups, the gingival margin showed more
leakage than the occlusal margin. There was a statistically significant
difference (p <0.05) between the cavity preparation methods in both SEM and
microscope.

Conclusion: Although the rate of microleakage of the cavity preparation and the
material used the most dense microleakage is seen in the gingival region. The
Er:YAG laser method is predicted to be an alternative to the conventional
method.

Farklı kavite preparasyon yöntemi kullanılarak prepare edilen sınıf V kavitelerinin farklı cam iyonomer simanlarla restore edilerek mikrosızıntısının değerlendirilmesi

Amaç: Bu çalışmanın amacı; farklı kavite preparasyon tekniği kullanılarak
prepare edilen sınıf V kavitelerin, cam iyonomer materyali ile restorasyonu
sonrası okluzal ve gingival bölge de oluşan mikrosızıntı seviyelerini
belirlemektir.

Gereç ve Yöntemler: Bu çalışmada; ortodontik veya periodontal sebeplerle çekilmiş ve herhangi
bir çürük, restorasyon ya da yapısal bir bozulma olmayanlar molar dişler (n:90)
kullanılmıştır. Her bir dişin bukkal yüzeyinde standart sınıf V kaviteler 3 mm
genişliğinde, 2 mm yüksekliğinde ve 1,5 mm derinliğinde olacak şekilde açılmıştır.
Kavite preparasyon tekniğine (Er:YAG lazer, Er,Cr:YSGG lazer ve konvansiyonel
yöntem) göre 3 ana gruba (n:30) ayrılan dişler, kendi aralarında da 3 farklı
ticari markalı konvansiyonel cam iyonomer siman ile restore edilerek 3 alt
gruba (n:10) ayrılmıştır. Örnekler stereomikroskopta X16 büyütmede ve SEM de
incelenmiştir. Veriler Kruskal-Wallis ve Wilcoxon testleri ile istatiksel
olarak 0.05 anlamlılık düzeyinde değerlendirilmiştir.

Bulgular: Hem SEM hem de mikroskop ile incelenen tüm gruplarda gingival kenar,
okluzal kenara göre daha fazla sızıntı göstermiştir. Kavite preparasyon
yöntemleri arasında hem SEM hem de mikroskop incelemelerinde istatistiksel
olarak anlamlı fark (p<0.05) bulunmuştur.

Sonuç: Kavite preparasyonu ve kullanılan materyale göre mikrosızıntı görülme
oranları değişse de en yoğun mikro sızıntı gingival bölgede görülmektedir.
Çalışmamızda kullanılan Er:YAG lazer yönteminin konvansiyonel yönteme
alternatif olabileceği öngörülmektedir.
