COMPARATIVE EVALUATION of pH of NEW ROOT-END FILLING MATERIAL

Abstract

Aim: This study aimed to comparative evaluation the pH of BioAggregate, Mineral Trioxide Aggregate MTA and MTA-Angelus in- vitro in a simulated periapical environment. Materials-Methods: Materials were mixed according to the manufacturers’ instructions and placed in polyethylene tubes 10mm x 1.5mm dia. using a lentulo spiral. The samples were then placed in glass flasks containing 5 ml distilled water. The pH of the solutions was measured at 1, 2, 3, 24, and 72 hours using pH meter. One-way ANOVA and Tukey tests were used for statistical analysis of data. Results: All the materials showed alkaline pH. The highest mean pH values for all materials were observed at 24 hours. Mean pH values for all materials were significantly lower at 1, 2 and 3 hours than at 24 and 72 hours p0.05 . Comparisons among root-end filling materials showed pH values of MTA-Angelus was significantly higher than those of MTA and BioAggregate at 72 hour p>0.05 . Conclusion: As a result of this in-vitro study determined that BioAggregate, MTA and MTAAngelus to have similar pH characteristics

Kök ucu dolgu materyallerinin pH’sının karşılaştırmalı değerlendirilmesi

Abstract

Amaç: Bu çalışmanın amacı; in-vitro olarak periapikal ortam taklit edilerek, BioAggregate, Mineral Trioksit Aggregate MTA ve MTAAngelus’ın pH’sının karşılaştırmalı değerlendirilmesidir. Gereç ve Yöntem: Üretici firma talimatlarına göre hazırlanan kök ucu dolgu materyalleri, lentülo yardımıyla polietilen tübüllere 10mm x 1.5mm yerleştirilerek, içerisinde 5ml distile su bulunan cam kaplara konuldu. Solüsyonların pH’sı 1., 2., 3., 24. ve 72.saatlerde pH metre kullanılarak ölçüldü. Elde edilen verilen istatistiksel analizinde one-way ANOVA ve Tukey testleri kullanıldı. Bulgular: Bütün deney periyotlarında tüm materyallerin alkalin pH’ya sahip olduğu ve en yüksek ortalama pH değerinin 24. saatte gözlendiği belirlendi. Materyallerin 1., 2. ve 3. saatlerdeki pH değerlerinin 24. ve 72. saatlerden anlamlı olarak düşük olduğu p0,05 . Kök ucu dolgu materyalleri karşılaştırıldığında ise, sadece 72. saatte MTA-Angelus’ın ortalama pH değerinin MTA ve BioAggregate’ten istatistiksel olarak daha yüksek olduğu görüldü p>0,05 . Sonuç: İn vitro olarak yapılan bu çalışma sonucunda, BioAggregate, MTA ve MTA- Angelus’ın benzer pH özelliklerine sahip olduğu belirlendi
