Stepwise and One Step Techniques In Deep Dentin Lesion
Study Details
Study Description
Brief Summary
This double blind, randomized, controlled clinical trial aimed to observe the success of stepwise (SW) and one step (OneS) excavation techniques in the management of deep dentin caries. Additionally, evaluation of glass ionomer cement (GIC) as temporary restorative was also performed. For this purpose, forty participants were selected among the routine patients coming to university clinic. A permanent tooth having caries lesions penetrating to 75 percentage or more of dentin of patient were included. Randomization to SW and OneS groups were organized by coin method. The periphery of the cavities including enamel-dentin junction was cleaned until reach to hard dentin. Afterwards, selective removal to soft dentin on the pulpal side of the cavities was applied manually excavation and covered with pure calcium hydroxide and zinc oxide eugenol cement. GIC was used for temporary filling. This process was implemented both the first stage excavation of SW and OneS groups. Clinical and radiographic evaluations were performed at 6 months according to clinical signs and symptoms and radiographic sings using Periapical Index (PAI). Besides, temporary restorations were evaluated according to the of Ryge/Modified USPHS criteria. Following this evaluation, on the SW group, the cavities was re-entered and selective removal was applied up to firm dentin and pulp-capping were applied as mentioned above. In OneS group, temporary restoration was reduced as a base. All of the cavities were permanently restored with resin composite. Whole procedure was completed at one centre by a specialist, and control sessions was performed two experienced experts. Participants and experts were blinded in this study.

Experimental: SW stepwise excavation |
Procedure: Stepwise Excavation
stepwise excavation includes selective caries removal to soft dentine on pulpal wall in the first stage of the excavation and
after six months, the second stage of intervention includes re-entring the cavities and wall selective removal to firm dentine on pulpal wall.

Experimental: OneS one step excavation |
Procedure: One Step Excavation
*one step excavations is completed in the first stage via performing selective removal to soft dentine on pulpal wall of the cavities.

Outcome Measures
Primary Outcome Measures
- Pulpal Success Assessment [a 6-month periods]
Presence of vitality in treated tooth with positive response to electrical and thermal stimuli, no history of spontaneous pain and no response to percussion and pain (sensitivity) sign in palpation
- Health Status of Periapical Tissue [a 6-month periods]
According to Orstavik' Periapical Index (PAI), Periapical Index score scale are 1to 5 : scoring with PAI 1 or PAI 2 refer to healthy tooth but PAI 3, PAI 4 and PAI 5 as worse outcome for periapical tissue that sing of periapical tissue damage
