Chemical Analysis of Femtosecond Laser Irradiated Enamel

Abstract

Aim: The aim of the study was to assess the chemical alterations in enamel after femtosecond laser irradiation. Material and Methods: Fifteen molars were used in the experiment, with 3x3 mm² areas prepared on the buccal surfaces of each tooth. These areas were irradiated using a Ti laser system (800 nm, 90 fs, 1-3 kHz) for 15 seconds. To assess the chemical composition of the samples before and after laser treatment, energy dispersive X-ray spectroscopy (EDX) was employed. This analysis measured the mean weight percentage (wt%) of minerals including calcium (Ca), phosphorus (P), carbon (C), aluminum (Al), oxygen (O), magnesium (Mg), potassium (K), and sodium (Na). Results: The mean wt% of all tested minerals were changed. While the change in O, P, Al ions was found to be significant (p < 0.05), the change in Ca, Mg, Na, C was found to be insignificant (p > 0.05). Conclusion: Our results indicate that femtosecond laser irradiation influences the mineral composition of the enamel. Keywords: Femtosecond laser, Mineral content, Enamel

Femtosaniye Lazer ile Pürüzlendirilen Minenin Kimyasal Analizi

Abstract

Amaç: Bu çalışmanın amacı femtosaniye lazer ile ışınlanmış minenin kimyasal değişimlerini değerlendirmektir. Gereç ve Yöntemler: On beş molar diş kullanıldı. Dişlerin bukkal yüzeylerinde 3x3 mm2'lik alanlar hazırlandı. Hazırlanan yüzeyler Ti:Sapphire lazer sistemi (800 nm, 90 fs, 1-3 kHz) ve 15 s süre ile ışınlandı. Örneklerin işlem öncesi ve sonrası kimyasal içerik analizleri enerji dağılımlı X-ışını spektroskopisi (EDX) ile yapıldı. Kalsiyum (Ca), fosfor (P), karbon (C), alüminyum (Al), oksijen (O), magnezyum (Mg), potasyum (K), sodyum (Na) mineral içeriğindeki ortalama ağırlık yüzdesi (ağırlıkça %) değerlendirildi. Bulgular: Test edilen tüm minerallerin ağırlıkça ortalama % değerleri değişmiştir. O, P, Al iyonlarındaki değişim önemli bulunurken (p < 0.05), Ca, Mg, Na, C'deki değişimler eöenmli değildir (p > 0.05). Sonuç: Bulgularımız minenin mineral içeriğinin femtosaniye lazer ışınlamasından etkilendiğini göstermektedir. Anahtar Kelimeler: Femtosaniye lazer, Mineral içeriği, Mine
