Aktiver Komparator: Pediatric NiTi rotary files manufactured with AF-H Wire technology
Pediatric NiTi rotary files manufactured with AF-H Wire technology are designed to improve flexibility and cyclic fatigue resistance while facilitating efficient canal preparation.
Clinical studies have reported significantly reduced instrumentation time using this rotary system compared with conventional hand instrumentation.
Furthermore, the system has demonstrated favorable canal shaping ability and a high percentage of optimally obturated canals, indicating its effectiveness in pediatric pulpectomy procedures
|
After preoperative radiographic assessment and administration of local anesthesia, lower primary molars will be isolated using a rubber dam and caries will be removed.
Working length will be determined radiographically, and root canal preparation will be performed using pediatric NiTi rotary files manufactured with AF-H Wire technology with 1% sodium hypochlorite irrigation between files.
Instrumentation time will be recorded throughout the procedure.
The canals will then be dried and obturated with Metapex and zinc oxide eugenol, followed by restoration with glass ionomer cement and a stainless steel crown.
Obturation quality will be evaluated postoperatively using digital radiography according to the Coll and Sadrian criteria.

Experimental: Pediatric NiTi rotary files manufactured with blue wire technology
Pediatric NiTi rotary files manufactured with blue wire technology are a newer pediatric rotary system developed using blue heat-treated NiTi technology.
Heat treatment enhances flexibility, resistance to cyclic fatigue, and fracture resistance, which are important characteristics when preparing the curved canals of primary teeth.
Laboratory studies have shown that blue wire pediatric rotary files exhibit excellent mechanical properties and superior cyclic fatigue resistance compared with several other pediatric rotary systems.
However, clinical evidence evaluating its performance in terms of instrumentation efficiency and obturation quality remains limited.

The total instrumentation time will be recorded from the start of the procedure until the canals are fully prepared.
Timing will begin with the insertion of the first file and will end after the final irrigation.
It will be measured in minutes using a stopwatch

The quality of obturation will be evaluated according to the criteria of Coll and Sadrian criteria (1996). The apical seal will measured in millimeters from the apical end of the canal filling material to the radiographic apex and scored as 1, 2, or 3.
