AIM To analyse the effect of ferrule height upon the mechanical resistance and stress distribution within a root to explain variations in the pattern of root fracture. METHODOLOGY An extracted, intact, caries free, maxillary right central incisor was scanned by laser and then reconstructed on a computer to produce a model of the tooth and associated periodontal ligament. A simulated post/core...

Crown lengthening surgery is a common periodontal procedure carried out to increase the amount of tooth exposure for aesthetic or restorative purposes. It crucial clinicians understand effect crown on tissues prevent relapse over treatment. Even though various clinical parameters have been used by researchers in past quantify suprastructure exposed, use digital technology has not widely adopted...

Restoration of endodontically treated teeth becomes especially complex when the involved teeth have previously undergone trauma, treatment for caries, fractures, endodontic-access preparation, canal instrumentation and other idiopathic causes. Excessive loss of dental hard tissues and inadequate maxillomandibular relationship possess difficulties for the esthetic result of subsequent prosthetic...

Melanin is a pigment that contributes to our skin color. Hyperpigmentation where melanin is produced in excess quantity can cause significant esthetic problem. Facial aesthetics is affected by smile line. Gingiva is an integral component of facial esthetics. Hyperpigmentation in gingiva affects facial esthetics. Various surgical modalities have been employed to correct hyperpigmentation. But, r...

Background. This study aimed to compare the analgesic effects of Ibuprofen and bromelain after periodontal surgery. Methods. A double-blinded crossover clinical trial was conducted on 22 patients needing two crown lengthening surgeries without bone surgery or with limited quadrants maxilla, control test sides. Each quadrant randomly assigned (500 GUD) ibuprofen (400 mg). Immediately 6 hours it,...

Abstract: Taking into account the unusual crystalline structures of 18-crown-6/peptides/water complexes, the links between their thermokinetic behaviour and the structural peculiarities are discussed. It has been found that the peptide chain lengthening leads to an increase in the temperature and activation energy of decomposition. The thermodynamics of complexation between small peptides and 1...

BACKGROUND In order to restore severely attrited teeth properly, surgical intervention in the form of a crown-lengthening procedure may be required. And also, proper diagnosis and treatment sequencing is critical to obtain a successful results. Adequate diagnostic wax-up ensures good esthetics and healthy periodontal tissue. CASE DESCRIPTION This clinical case report describes a diagnosticall...
