Abstract

Tooth discoloration can cause social and psychological problems and lead to loss of self-confidence in children. Concerns of parents and children on appearance and esthetics increase the importance of dental esthetic treatments in children. External tooth discoloration in children can be seen in both the primary and the permanent teeth. Poor oral hygiene, use of iron preparations and chromogenic bacteria are among the etiology of external tooth discoloration. Chromogenic bacteria can cause black/brown, green, orange or blue discolorations on the tooth surfaces of children. For clinicians, most interesting external tooth discoloration in children has been the black discoloration, which is more frequently observed compared to the other types. Most of the studies also have focused on the chromogenic bacteria associated with black discolorations, and the data concerning other types of discoloration are limited. Our knowledge on the existing chromogenic bacterial mechanisms is increasing by the developing microbiological diagnostic procedures, and new species associated with discoloration are becoming recognized. Still, studies dealing with the mechanisms of the chromogenic bacteria leading to discoloration are insufficient in the accessible sources. The objective of this article is to emphasize the role of the chromogenic bacteria in external tooth discoloration in children, to review precautions that can be taken to prevent discoloration, and current treatment methods, and to contribute to the current knowledge of the clinicians on this subject.

Çocuklardaki dış kaynaklı diş renklenmelerinde kromojenik bakterilerin rolü

Abstract

Diş renklenmeleri, çocuklarda sosyal ve psikolojik sorunlara yol açarak özgüven kayıplarına sebep olabilmektedir. Ebeveynlerinin ve çocukların dış görünüşleriyle ilgili kaygıları ve estetik arayışları, günümüzde diş hekimliğinde çocuklardaki estetik tedavinin önemini arttırmaktadır. Çocuklarda dış kaynaklı diş renklenmeleri hem süt hem de daimi dişlenmede görülebilmektedir. Dış kaynaklı renklenmelerin etiyolojisinde kötü ağız hijyeni, demir preparatlarının kullanımı ve kromojenik bakteriler yer almaktadır. Kromojenik bakteriler, çocuklarda diş yüzeyinde siyah/kahverengi, yeşil, turuncu veya mavi gibi renklenmeler oluşturabilmektedir. Çocuklarda görülen dış kaynaklı diş renklenmeleri arasında, klinisyenlerin en çok ilgisini çeken, daha sık karşılaşılan siyah renklenmeler olmuştur ve araştırmaların birçoğu buna yol açan kromojenik bakteriler üzerine yoğunlaşırken, diğer renklenmelerle ilgili veriler sınırlı kalmıştır. Gelişen mikrobiyolojik tanı yöntemleriyle, mevcut kromojenik bakterilerin mekanizmaları hakkındaki bilgilerimiz artmakta ve renklenmeye neden olan yeni bakteriler tespit edilebilmektedir. Ancak, ulaşılabilir kaynaklarda kromojenik bakterilerin renklenmeye yol açan mekanizmalarıyla ilgili çalışmalar yetersiz kalmıştır. Bu makalede, çocuklardaki dış kaynaklı diş renklenmelerinde kromojenik bakterilerin rolünün vurgulanması, bu renklenmelerin tedavilerinin ve alınabilecek önlemlerin gözden geçirilmesi ve klinisyenlerin bu konudaki mevcut bilgilerine katkı sağlanması amaçlanmaktadır.
