Introduction: Although rotary instrumentation has been widely studied in permanent dentition, it is a rather new field of study concerning primary teeth. Purpose: We aimed to evaluate apical displacement and time needed for instrumentation of root canals of primary molars by manual and rotary techniques. Materials and Methods: Root canals of 144 extracted first and second primary maxillary mola...

The approach presented in this paper aims to support developers by delivering methods and IDE-based tools for semi-automatic source code instrumentation that improve efficiency and consistency of the instrumentation process, and thus reduces the overall effort to be put into instrumentation. Our solution focuses on code generation for logging and performance monitoring purposes. The resulting t...

The use of an ultrasonic apical preparation technique has been advocated recently. Root-end preparations in 30 extracted single-canaled human teeth were evaluated, comparing those prepared with ultrasonic instrumentation alone, or in combination with rotary bur preparation, to those prepared with rotary instrumentation alone. Specimens were evaluated for the presence of debris, smear layer, and...

In the April 2022 issue of Instrumentation & Measurement Magazine, some researchers' works related to instrumentation and measurement in China were introduced. Here, we continue share with readers other that conducted China.

Aim : To assess the cleaning efficacy of manual and automated instrumentation using 4% sodium hypochlorite singly and in combination with Glyde file Prep as root canal irrigant. Methodology : The study utilized 40 extracted human permanent premolars with single, straight and fully formed root. The teeth were then divided into four groups of ten each, Group I and II were prepared by manual instr...

OBJECTIVE The purpose of this study was to investigate the ultramorphology of the root surfaces induced by mechanical instrumentation performed using conventional curettes or piezoelectric scalers when used single-handedly or with a combined technique. MATERIAL AND METHODS Thirty single-rooted teeth were selected and divided into 3 groups: Group A, instrumentation with curettes; Group B instr...

AIM To compare root canal treatments performed before and after education in a nickel-titanium rotary technique (NiTiR) with respect to costs for instrumentation and number of instrumentation sessions in a County Public Dental Service in Sweden. METHODOLOGY   Following education, 77% of the general dental practitioners adopted completely the NiTiR. The randomly selected sample comprised 850 r...
