Abstract

Amaç:
Bu in vitro çalışmanın amacı Siyanoakrilat (Periacryl) ve tetra-kalsiyum fosfat
ve dikalsiyum fosfat içerikli desensitizerin (Teethmate) kombine ve tekli uygulamalarının
kalıcılığının ve dentin tübüllerine etkisinin değerlendirilmesidir.

Gereç ve Yöntemler:
Gömülü 20 yaş dişlerinden 140 dentin preparatı elde edilmiştir. Preparatlar 7
gruba ayrılmıştır (n=20). Hiçbir uygulama yapılmayan preparatlar “K” kontrol, %6
sitrik asitte 1 dk. bekletilenler PS ( Periacryl ) TS (Teethmate )  PTS(kombine uygulama)   ; 24
saat yapay tükürükte bekletilenler TY (Teethmate ) PY (Periacryl ) PTY (kombine
uygulama ) olarak gruplanmıştır. Uygulama tamamlandığında preparatlar SEM
cihazı kullanılarak morfolojik yapıları, açık dentin tübül alanları ve açık
dentin tübül çapları açısından değerlendirilmiştir.

Bulgular:
Açık dentin tübüllerinin alanı kontrol grubuna kıyasla PS, PY, PTS ve PTY
gruplarında azalmıştır (p>0,05). Numunelerdeki açık dentin tübül çap
ortalamaları kontrol grubuna göre PS, PY, PTY, PTS ve TY gruplarında anlamlı
derecede azalmıştır (p>0,05) . Sitrik asit uygulanan gruplarda istatistiksel
olarak anlamlı bir farklılık yokken yapay tükürük uygulanan gruplarda açık
dentin tübül çap ortalaması, PTY grubunda TY grubundan istatistiksel olarak
anlamlı derecede küçüktür (p>0,05) .  

Sonuç:
Periacryl dentin hassasiyet tedavisinde kullanılabilecek bir preparat olmakla birlikte
kombine kullanımda Teethmate ’in kalıcılığını arttırmaktadır.

Evaluation of the effect of different desensitizers on dentin tubules: An in vitro scanning electron microscopy analysis

Abstract

Aim:
The aim of this in vitro study is to evaluate the persistence of the combined
and single applications of cyanoacrylate (Periacryl) and tetra-calcium
phosphate + dicalcium phosphate containing desensitizer (Teethmate) and their
effect on dentin tubules.

 

Material and Methods: 140 dentin samples were obtained from impacted third molars. The samples
were divided into 7 groups (n = 20). Samples without any application named as K
(control), samples were subjected to 6% citric acid solution for 1 min; PS
(Periacryl) TS (Teethmate) PTS (combined application). Samples were immersed in
artificial saliva for 24 hours named as; TY (Teethmate) PY (Periacryl) PTY
(combined application). When the application was completed, the preparations
were evaluated by scanning electron microscopy in terms of morphological
structures, open dentin tubule areas and open dentin tubule diameters.

Results:
The area of ​​open dentin tubules decreased in PS, PY, PTS and PTY groups
compared to the control group (p> 0.05). The mean diameter of the open
dentin tubule in the samples was significantly decreased in the PS, PY, PTY,
PTS and TY groups compared to the control group (p> 0.05). While there was
no statistically significant difference in citric acid treated groups, the mean
dentin tubule diameter was significantly lower in the group with artificial
saliva than the TY group in the PTY group (p> 0.05).

Conclusion:
Periacryl is a preparation that can be used in the treatment of dentin
sensitivity, however, it increases the retention of Teethmate in combined use.
