Overview

Brief Summary

The primary aim is to compare the behavior of the children during using conventional manual instrumentation versus rotary instrumentation by single rotary system for pulpectomy in primary molars through a Randomized Clinical Trial.

The main question it aims to answer is:

Is there a difference in the behavior of the children when using single rotary file system versus manual instrumentation in pulpectomy in primary molars?

Detailed Description

Pulpectomy has gained popularity in the pediatric dental practice for preserving the primary teeth in its position until exfoliation. There has been a paradigm shift from using manual instrumentation to rotary instrumentation for canal preparation in primary teeth. While studies show that there is a reduction in the instrumentation time with the use of rotary instruments which in turn influences the behavior of the child, its direct effect on the behavior of the children has not been evaluated .

The behavior of children plays an integral component and is the primary requisite of the pediatric dental practice. Assessment of child's behavior during a dental procedure is one of the most important skills of a pediatric dentist for successful completion of the dental treatment .

Interestingly, it has been noted that the treatment duration of patients with anxiety or behavior management problem is on average 40% more than that of normal patients going through the same procedure .

Much attention has been directed toward making pulpectomy a less time-consuming and a more-efficient procedure. These challenges lead to the introduction of rotary endodontics in pediatric dentistry. However, the bizarre root canal morphology and thinner root dentin limited the use of rotary endodontics in primary teeth. Various modified protocols have been introduced to overcome such barriers to prevent undesirable complications.

With these options, dentists can perform the pulpectomy with less psychological trauma to the child thus decreasing the anxiety and instilling positive behavior. The acceptance rate of the proposed method of treatment by the child may also increase. Furthermore, the use of a rotary file system may maintain a balance between the treatment duration and efficient behavior management in children.

Arms & Interventions

Group I pulpectomy using single rotary file system

Experimental

Administration of local anesthesia at the side of the affected tooth. Application of the rubber dam for isolation, then a standardized pulpectomy procedure will be performed using a large sterile round end bur in a high-speed hand piece with copious irrigation. After opening the access cavity, the root canal patency was checked for all the canals located using a size #10 (0.02%) k-file then a single rotary file (20 taper 4) will be adjusted on the desirable working length depending on an electronic apex locator (1 mm shorter than the apex) and used in pulpectomy in a brushing motion at the rotational speed 300 rpm with torque set at the lowest level, irrigation with saline.

Intervention: Fanta AF F one rotary files 20 taper 4 (Device)

Group II pulpectomy using manual files system

Active Comparator

Administration of local anesthesia at the side of the affected tooth. Application of the rubber dam for isolation, then a standardized pulpectomy procedure will be performed using a large sterile round end bur in a high-speed hand piece with copious irrigation. After opening the access cavity, manual files (k files, Mani, Inc., Japan) size 15,20,25,30 will be adjusted on the desirable working length depending on an electronic apex locator (1 mm shorter than the apex) and used in pulpectomy in a brushing motion, irrigation with saline.

Intervention: Manual files (k files ,Mani, Inc., Japan). (Device)

Outcomes

Primary Outcomes

• child's behavior level

Time Frame: Immediately after treatment

child's behavior level using Frankl's behavior rating scale * rate 1 means definitely negative "refusal of treatment , fearfulness" * rate 2 means negative "reluctance to accept treatment , uncooperative" * rate 3 means positive "acceptance of treatment , patient follows the dentist's directions" * rate 4 means definitely positive " good rapport with the dentist , laughter and enjoyment"

Secondary Outcomes

  • Post-operative pain(at 6, 12, 24, 48 and 72 hours and 1 week after treatment.)
  • Obturation quality(Immediately after treatment.)
  • Instrumentation time(During treatment)
