Deep Marginal Acquisition With Thermacut Bur Vs. Functional Crown Lengthening in Deep Carious Lesions

Deep Caries Clinical Trial

Official title:
Deep Marginal Acquisition With Thermacut Bur Versus Functional Crown Lengthening in Management of Deep Subgingival Interproximal Carious Lesions: A One Year Follow-up Randomized Controlled Trial

Clinical Trial Summary

this clinical trial is conducted to compare between deep marginal acquistion by the means of thermacut bur Vs. functional crown lengthening in exposing deep subgingival interproximal cervical lesions

Clinical Trial Description

Deep subgingival margins pose a great difficulty during restorative work with composite restorations. Exposing cavity margins is paramount in order to attain proper isolation, matrix adaptation and composite placement. Several methods have been proposed to overcome the problem of exposing deep margins; functional crown lengthening is considered the gold standard of care regarding exposure of deep margins. However, functional crown lengthening can pose many problems including the risk of root exposure, furcation involvement and compromising crown root ratio, besides risk of thread exposure if it is done beside implant, removal of bone from adjacent teeth and from buccal and lingual walls in order to create smooth bone architecture, and the complications of surgery such as post-operative pain, inflammation and edema and the risk of excessive bleeding. Deep marginal acquisition and deep marginal extension (DMA & DME) are considered as a viable option in treating deep subgingival extended margins. Several methods regarding deep marginal acquisition have been proposed including the use of diode laser and Electrosurgery, there is another protocol for exposing the gingival seat by the use of thermacut bur. The rationale behind conducting this research is to propose an easy and predictable way to expose deep subgingival margins, without the need to perform surgical intervention. The technique is done by clinicians with good outcomes, but never been tested or validated, this study is performed to verify whether this test should be validated or not. ;
