ABSTRACT
 Objective: There is not enough information about the effect of digital impression scanning using right/left hand on the scanning time. The purpose of this study was to evaluate whether the scanning time of digital impression with an intraoral scanner is dependent upon the handedness of the operator. Material and Methods: Two voluntary fourth-year students and 2 prosthodontists from the Yeditepe University, School of Dentistry were included. One of the students and prosthodontists were right-handed while the others were left-handed. For the experiments, 100 models containing 16 teeth on the maxillary arch were adapted in sequence to a phantom head that positioned uprightly. The participants were divided into 4 groups according to handedness of students and prosthodontists. Each group was divided into 2 subgroups according to right and left quadrants of scanned model. The scanning time was measured and recorded in seconds with a chronometer in all groups. Mann-Whitney U test was used to compare the groups, with a significance level established at p

ÖZET
 Amaç: Dijital ölçüde sağ/sol el kullanılarak tarama yapılmasının, tarama zamanı üzerindeki etkisi ile ilgili yeterli bilgi bulunmamaktadır. Bu çalışmanın amacı, dijital ölçü tarama zamanının, diş hekiminin sağ/sol el kullanmasına bağlı olup olmadığının değerlendirilmesidir. Gereç ve Yöntemler: Yeditepe Üniversitesi Diş Hekimliği Fakültesinden 2 gönüllü 4. sınıf öğrencisi ve 2 protez uzmanı çalışmaya dâhil edildi. Öğrencilerden biri ve bir protez uzmanı dijital ölçü taraması için sağ elini kullanırken, diğer 2 hekim sol elini kullandı. Çalışma için 100 adet üst çene modeli (16 diş) fantoma yerleştirildi. Çalışmaya katılanlar sağ/sol elini kullanan öğrenci ve protez uzmanı olarak 4 gruba ayrıldı ve sırasıyla modelleri taradı. Her grup, modelin sağ ve sol yarısı taramasına göre 2 alt gruba ayrıldı. Tarama süresi ölçüldü ve tüm modeller için kronometre yardımıyla sn bazında kaydedildi. Grupların karşılaştırılmasında Mann-Whitney U testi kullanıldı. Anlamlılık p<0,05 düzeyinde değerlendirildi. Bulgular: Öğrenciler (24,37 sn) ve protez uzmanlarının (12,36 sn) tarama zamanları arasında istatistiksel olarak ileri düzeyde anlamlı farklılık bulundu. Sağ el kullanan protez uzmanı ve öğrenci için kaydedilen tarama zamanı, sol el kullanan protez uzmanı ve öğrenci için kaydedilen tarama zamanından yüksek bulundu (p=0,001; p<0,05). Sonuç: Çalışmamızın sonucunda, sol el kullanan diş hekimlerinin sağ el kullananlara göre el becerilerinin, tecrübe sürelerine bakılmaksızın daha iyi olduğu düşünülebilir. Öğrencilerin, uzmanların yeterlilik düzeyine ulaşmaları için daha fazla eğitim ve tecrübeye ihtiyaçları vardır.
