NCT04102293

Brief Summary

The aim of this study is to evaluate the quality of obturation and the time efficiency of rotary versus manual instrumentation in roots of deciduous molars clinically where the:

  • Primary objective Is to evaluate the time efficiency
  • Secondary objective Is to evaluate the quality of obturation Clinical and radiographical follow up will be performed for 18 months to investigate the clinical and the radiographic success for the Conventional and Rotary groups.

Outcome Measures

Primary Outcomes (2)

  • Is to evaluate the time efficiency of the rotary mm files versus manual stainless steel k files in the pulpectomy of lower second primary molars affecting the positive behavior of the child

    Time efficiency of instrumentation using rotary mm files specially designed for primary teeth versus manual stainless steel K-files in the pulpectomy of mandibular second primary molars, by clinical and radiographic evaluation for 18 months.

    up to 18 months

  • Is to evaluate and compare the quality of obturation using two different obturation techniques following instrumentation by rotary mm files and manual stainless steel k files instrumentation in another group

    The quality of obturation using ZOE will be performed with either the incremental technique or the modified disposable syringe technique, following instrumentation by rotary and manual files, where the grading will be as : 1: overfilled, 2: underfilled 3: optimum filling.

    up to 18 months

Study Arms (4)

Eligibility Criteria

Age4 Years - 7 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Children included in the study should conform to the following criteria:
  • Patients between ages 4-7 years old with at least one mandibular vital or non-vital primary molar indicated for pulpectomy will be selected.
  • Absence of periapical or interadicular radiolucencies, inflammatory root resorption, sinus tract or gingival abscess.
  • No physiological root resorption.
  • The teeth should have enough coronal structure for full coverage Stainless-Steel crowns.

You may not qualify if:

  • \. Children who are extremely uncooperative and difficult to manage 2. Children suffering from any physically or mentally disability that will complicate the treatment: Special Health Care needs (SHCN) 3. Teeth of poor prognosis due to presence of an abscess or a sinus, mobility, advanced bone or root resorption or Non-Restorable teeth.
