**Official Title:** Postoperative Pain After Pulpectomy of Primary Molars Using Two Different Root Canal Obturation Techniques: A Randomized Clinical Trial

**NCT ID:** [NCT06424353](https://clinicaltrials.gov/study/NCT06424353)

## Key Facts

- **Status:** RECRUITING
- **Phase:** NA
- **Study Type:** INTERVENTIONAL
- **Target Enrollment:** 100
- **Lead Sponsor:** Minia University
- **Conditions:** Postoperative Pain
- **Start Date:** 2024-01-20
- **Completion Date:** 2024-06
- **CT.gov Last Update:** 2024-05-22

## Brief Summary

Testing postopertive pain after pulpectomy of primary molars with endoflas using modified Wong-Baker scale of pain.

## Detailed Description

Testing postopertive pain after pulpectomy of primary molars with endoflas using lentilospiral files and pressure seringe by using modified Wong-Baker scale of pain.

## Eligibility

- **Minimum age:** 5 Years
- **Maximum age:** 7 Years
- **Sex:** ALL
- **Healthy Volunteers:** No

```
Inclusion Criteria:

* The current study will include children who meet the following clinical and radiographic criteria:

3.1a.Clinical:

1. 5-7-year old children categorized as class I or II according to American Society of Anaesthesiologists (ASA) scale.
2. Children rated as no.3 or 4 in Frankel behavior rating scale (FBRS).
3. Presence of at least one primary molar with deep carious lesion.
4. Asymptomatic necrotic molars confirmed by the absence of bleeding on opening of the pulp chamber.

3.1b. Radiographic:

1. Extensive caries approaching to the pulp.
2. Presence of at least two-thirds of root length.

Exclusion Criteria:

* A child's tooth with any of the following criteria:

3.2a. Clinical findings:

1. History of spontaneous unprovoked toothache.
2. Extensive crown destruction that preclude coronal restoration.
3. Presence of adjacent or opposing tooth with deep carious lesion "in the same side".
4. History of administering analgesics 12 hours before tooth obturation.

3.2b. Radiographic findings:

1. Presence of a large furcation or periapical radiolucency approximating the succedaneous tooth.
2. Presence of pathological internal/external root resorption.
3. Absence of underlying permanent successor.
```

## Arms

- **lentilospiral group** (EXPERIMENTAL) — Obturation of primary molars with calcium hydroxide, eugenol and iodoform paste using paste carrier files(lentiospiral files)
- **pressure seringe group** (ACTIVE_COMPARATOR) — Obturation of primary molars with calcium hydroxide, eugenol and iodoform paste using pressure seringe

## Interventions

- **Endoflas pulpectomy** (PROCEDURE) — obturation of root canals of primary molars with Endoflas using pressure seringe and lentilospiral files

## Primary Outcomes

- **postoperative pain** _(time frame: after one day and after one week)_ — Measuring post operative pain after pulpectomy with two different obturation techniques using (Modified Wong-backer scale of pain )which have four scales from( 0 to 3) which 0 is the better outcome( no pain) and 3 is the worst (severe pain)
