Abstract
The purpose of the present study was to assess the clinical and radiological outcome following repair of furcal perforation by mineral trioxide aggregate (MTA) and intermediate restorative material (IRM) in mandibular molar teeth. Forty teeth having furcal perforation were enrolled in this study, out of which 20 teeth were treated with MTA and the remaining 20 teeth were subjected to IRM treatment. Following perforation repair, all teeth were subjected to root canal treatment followed by final restoration. Clinical and radiological outcome was evaluated at 3, 6 and 12 months interval. The results showed that in both MTA and IRM groups, pain, tenderness on percussion as well as swelling and sinus was gradually decreased with the increase of the observation period. Furthermore, the widening of the periodontal ligament space and communi-cation with the oral cavity were gradually decreased. Although there was no significant differences between MTA and IRM at 3 and 6 months observation period but at 12 months, the clinical outcome between MTA and IRM was statistically significant (p<0.05). It can be concluded that repair of furcal perforation by MTA showed more effective than that of IRM.
Highlights
Furcal perforation is considered as one of the major complications leading to the failure of endodontic treatment.[1]
Interest has centered on the use of mineral trioxide aggregate (MTA), which is considered to fulfill the requirement of an ideal material for perforation repair.[5, 6]
Teeth were divided by simple random sampling into two groups as follows: In Group I, 20 teeth with furcal perforation were repaired by MTA and in Group II, 20 teeth were treated by intermediate restorative material (IRM)
Summary
Furcal perforation is considered as one of the major complications leading to the failure of endodontic treatment.[1] It usually occurs during the preparation of an endodontic access cavities or exploring canal orifice of multirooted teeth.[2] it is defined as an artificial opening in a tooth or its root created by boring, piercing cutting or pathologic resorption which results in a communication between the pulp space and the periodontal tissue. Interest has centered on the use of mineral trioxide aggregate (MTA), which is considered to fulfill the requirement of an ideal material for perforation repair.[5, 6]
