About this trial

The aim of the study is to assess the Influence of proximal caries on outcome of direct pulp capping in permanent mandibular molars with sign of reversible pulpitis. objective- Primary objective- To evaluate and compare the clinical and radiographic outcome of Direct pulp capping in mandibular molars with occlusal and proximal carious lesions. Secondary objective- To evaluate and compare 1.OHRQoL after Direct pulp capping in occlusal and proximal lesion. 2. Postoperative pain, after Direct pulp capping in occlusal and proximal lesion Subjects of age group 15 - 40 yrs will be included and divided into two groups 1) Permanent mature molars with proximal carious lesion 2)Permanent mature molars with occlusal carious lesion.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Mature permanent mandibular molars with extremely deep caries that penetrate the entire thickness of dentine as detected on radiograph with reversible pulpitis will be included.

Participant with Reversible pulpitis will be diagnosed clinically based on discomfort experienced by the participant when a stimulus such as cold or sweet is applied and goes away within a couple of seconds following the removal of the stimulus, with no significant radiographic changes in the periapical region of the suspect tooth and the pain experienced is not spontaneous.

The pulpal sensibility will be confirmed through positive response to electric and cold tests (Endo frost) and the presence of bleeding after caries excavation. 4.Pulpal and the periapical diagnosis will be established based on the diagnostic terminology approved by American Association of Endodontists (AAE, 2019).

Disqualifiers

Mechanical or pulp exposure due to trauma

absence of exposure after excavation of caries

failure to achieve hemostasis within 5 mins

irreversible pulpitis and teeth having periapical lesions

Treatments tested in this trial

  • Direct pulp capping in proximal carious lesion

    Procedure/Surgery

    After pulp exposure, pulp wound will be irrgated with 3%NaOCl, and bleeding will be controlled by placing a cotton pellet soaked with 3%NaOCl over the pulpal wound for every 2 minutes till 6 mints. Hemostasis will be achieved with 3% NaOCl for upto 6 mins if required. The time used to control bleeding will be recorded for each tooth. Teeth with excessive uncontrollable bleeding even after 5 mins will be excluded from the study; however, definite treatment will be provided to the patient. Size of exposure will be measured to be between 0.5-1mm using CPITN probe and Mani ball bur - 45. After that, ProRoot MTA of 2-3 mm thickness will be applied over the lesion followed by the application of layer ofRMGIC. Then the tooth will be permanently restored with composite resin. After restoration, a postoperative periapical radiograph will be taken using a digital imaging system for comparative evaluation after 6 months and 12 months follow up.

Trial outcomes

Primary outcomes

1

Success rate at 12 months

: Criteria for success:- Clinical: 1. Absence of signs and symptoms of spontaneous pain or pain on stimulus and discomfort except for the first few days after treatment. 2. No tenderness to palpation or percussion and the tooth is functional. 3. Normal mobility and probing pocket depth. 4. Absence of associated soft tissue swelling, sinus or fistula. Radiographic: - 1. Absence of any periapical or interradicular radiolucency. 2. Complete radiographic healing (PAI score 1 or 2 acc. to Ostravik et al). 3. Absence of internal and external root resorption. Tooth will be considered successful when all the above parameters are met.

Time frame
18 months

Secondary outcomes

1

Postoperative pain

Post Operative Pain To assess incidence and intensity of pain postoperatively at every 24 hours till 7 days using Visual analogue Scale of 0 to 100 millimeter line. Score 0 means no pain and Score100 means maximum pain. To assess incidence and intensity of pain postoperatively at every 24 hours till 7 days using Visual analogue Scale of 0 to 100 millimeter line. Score 0 means no pain and Score 100 means maximum pain.

Time frame
Baseline and at 24 hours, Day 1, Day 2, Day 3, Day 4, Day 5, Day 6 and Day 7 after the treatment

OHRQoL assessment

OHIP-14 questionnare will be used to assess the quality of life.It consists of questionnaire in seven dimensions: functional limitation, physical pain, psychological discomfort, physical disability, psychological disability, social disability, and handicap. It will be scored using a Lickert scale: never=0; hardly ever=1; occasionally=2; fairly often=3; very often=4. Total score will be calculated ranging from 0-56, with higher score denoting the worst OHRQoL

Time frame
Baseline and at 24 hours, Day1,Day 2, Day 3, Day 4, Day 5, Day 6 and Day 7 after the treatment
