A Comparison Of Surface Roughness Of Dentin After Tooth Preparation With Conventional Rotary And Ultrasonic İnstrumentations
Öz
Background: The aim of
this in vitro study was to compare the surface roughness of tooth preparations
finished with only using rotary instruments and finished with rotary
instruments + an ultrasonic generating device.
Methods: Twenty
extracted, caries free, human molars preparations were performed using rotary
intruments with regular grit diamond burs. 10 of these prepared teeth were
selected and their preparations finished with diamond tips held in an
ultrasonic generating device. The surface roughness of prepared teeth was
recorded. The surface roughness was evaluated using different parameters like
Ra (arithmetic mean deviation of the roughness profile) and Rz (the average
distance between the five highest peaks and five deepest valleys within the
sampling length).
Results:According
to Ra parameter data, the surface roughness of teeth prepared with only regular
grit diamond burs using rotary instruments was statistically higher than those
of teeth prepared with regular grit diamond burs using rotary instruments +
diamond tips held in an ultrasonic generating device (p=0.002). According to Rz
parameter data, there was not significantly difference between the surface
roughness of these two groups (p>0.05).
Conclusions:
Within the limitations of this study, using the diamond tips held in ultrasonic
generating device for finishing the tooth preparation is an effective method to
reach smoother surfaces. But the average distance between the five highest
peaks and five deepest valleys within the sampling length of these two groups
are similar.
Key words: utrasonics, dental instruments, tooth preparation.

Frezlerle Ve Sonik Uçlarla Basamaklı Kole Preparasyonu Yapılmış Dişlerin Yüzey Pürüzlülüğünün Karşılaştırmalı Olarak Araştırılması
Öz
Amaç: Bu in
vitro çalışmanın amacı, sadece döner aletlerde kullanılan normal gren boyutlu
elmas frezlerle prepare edilen dişlerin yüzey pürüzlülüğü ile döner aletlerde
kullanılan normal gren boyutlu elmas frezler + özel ultra sonik uçlar
kullanılarak prepare edilen dişlerin yüzey pürüzlülüğünü karşılaştırmaktır.
Gereç ve Yöntemler: 20 adet yeni çekilmiş, çürüksüz molar diş bu çalışma için
seçilerek döner aletlerde kullanılan normal gren boyutlu elmas frezlerle
prepare edilmiştir. Bu dişlerin içinden 10 tanesi seçilerek bu dişlerin
preparasyonları özel ultrasonik uçlarla bitirilmiş ve böylece ikinci bir grup
oluşturulmuştur. Bu işlemlerin ardından
yüzey pürüzlülüğünün kaydı yapılmıştır. Yüzey pürüzlüğü Ra (yüzey profilinin
aritmetik ortalaması) ve Rz (yüzey pürüzlülük profilinin en yüksek beş noktası
ve en düşük beş noktası arasındaki dikey mesafe) gibi farklı parametreler
kullanılarak değerlendirilmiştir.
Bulgular:
Ra parametre değerlerine göre, sadece döner aletlerde kullanılan normal gren
boyutlu elmas frezlerle prepare edilen
grup dişlerin yüzey pürüzlülüğü, sonik aletlerle preparasyonu düzeltilen
grupa göre istatistiksel olarak daha yüksek bulunmuştur (p=0.002). Rz parametre
değerlerine göre ise, bu iki grubun yüzey pürüzlülük değerleri arasında
istatiksel olarak anlamlı bulunmamıştır (p>0.05).
Sonuçlar: Bu
çalışmanın sınırları dahilinde diş preparasyonunun özel ultrasonik uçlarla
bitirilmesinin daha pürüzsüz diş yüzeylerinin elde edilmesinde etkili olduğu
tespit edilmiştir. Ancak yüzey profilindeki en yüksek 5 nokta ile en derin 5
nokta arasındaki ortalama mesafenin (Rz) her iki grup için de benzer olduğu
görülmüştür.
