Abstract

ABSTRACT

Aim: Bleaching of discolored teeth is
one of the important issues of aesthetic dentistry. For this purpose, peroxides
have been used for many years. Ozone is a contemporary bleaching method used as a substitute for
hydrogen peroxide because of undesired side effects of peroxides. The aim of
this in vivo study is to compare
different bleaching methods including hydrogen peroxide (HP), laser activated
hydrogen peroxides and ozone.

Materials
and methods: A hundred patients were divided into 5
groups (n=20) for this study. Group 1: Bleaching with ozone. Group 2: Chemical bleaching with 40% HP gel. Group 3: Chemical bleaching with 35% HP gel. Group 4:
Bleaching with 40% HP gel + diode laser activation. Group 5: Bleaching with 35%
HP gel + diode laser activation. Color of the teeth before, immediately after bleaching
and 2 weeks later the treatment were evaluated with the CIE L*a*b*system.
Hypersensitivity was assessed with a Visual
Analogue Scale. Differences between the groups were statistically analyzed.

Results: Immediately after treatment color changes among the groups were
statisticall similar (p > 0.05) while at 2 weeks recall color change of
Group 1 was significantly less than the other groups (p < 0.05). In terms of hypersensitivity, Group 1 represented
significantly less values compared to the other groups (p < 0.05) while
other groups were statistically similar (p > 0.05).

Conclusions: HP is superior to ozone in
bleaching effectiveness. Ozone is safer in hypersensitivity. Activation with diode laser reduced the time but
did not affect bleaching effectiveness.

Key words: Hydrogen peroxide, hypersensitivity, laser, ozone, bleaching

OZON VE LAZER İLE AKTİVE
EDİLEN BEYAZLATMA METODLARINI TAKİBEN ETKİNLİK VE POSTOPERATİF HASSASİYETİN
DEĞERLENDİRİLMESİ

ÖZ

Amaç: Renklenmiş dişlerin
beyazlatılması, estetik diş hekimliğinin önemli konularından biridir. Bu
amaçla, uzun yıllardır, peroksitler kullanılagelmiştir. Ozon ise peroksitlerin
istenmeyen yan etkilerini taşımayan güncel bir beyazlatma yöntemidir. Bu in vivo çalışmanın amacı; hidrojen peroksit (HP), lazer aktivasyonlu HP ve ozon içeren beyazlatma
yöntemlerinin karşılaştırılmasıdır.

Gereç ve Yöntem: Bu çalışma için yüz hasta 5 gruba ayrıldı   (n = 20). Grup 1: Ozon ile beyazlatma; Grup
2: % 40 HP jel ile kimyasal beyazlatma; Grup 3: %35 HP jel   ile
kimyasal beyazlatma; Grup 4: %40 HP jel + diyot lazer aktivasyonu ile
beyazlatma; Grup 5: %35 HP jel + diyot lazer aktivasyonu. Beyazlatma tedavi öncesi,
sonrası ve 2 hafta sonrasında diş renkleri CIE
L*a*b* sistemi ile değerlendirildi. Hipersensitivite, Görsel Analog Skala
ile değerlendirildi. Gruplar arasındaki farklılıklar istatistiksel olarak
analiz edildi.

Bulgular: Tedavi hemen sonra gruplar
arasındaki renk değişimleri istatistiksel olarak benzer (p > 0.05) iken, 2
hafta sonra grup 1'deki renk değişimi diğer gruplara göre anlamlı derecede
düşüktü (p < 0.05). Hipersensitivite açısından ise grup 1 diğer gruplara
göre anlamlı derecede düşük değerler gösterirken (p < 0.05) diğer gruplar
istatistiksel olarak benzerdi (p > 0.05).

Sonuç: Ozon ile yapılan beyazlatma tedavisi,
hipersensitivite açısından daha güvenli bulunurken; beyazlatma etkinliği
açısından hidrojen peroksit daha üstün bulundu. 980 nm diyot lazer ile
aktivasyon tedavi süresini kısalttı ancak beyazlatma etkinliğine etki etmedi.
