Comparative evaluation of microleakage of four restorative materials using confocal laser scanning microscopy: an in vitro study.

Objective: Understanding the sealing ability of restorative materials to prevent microleakage and its consequent complications-such as secondary caries, postoperative sensitivity, and restoration failure-is imperative in clinical dentistry. This study aims to compare the microleakage performance of four restorative materials-bioactive composite resin (Activa Pronto), alkasite restorative (Cention N), compomer (Dyract Flow), and glass ionomer cement (Type 2 GIC)-in Class V cavities of extracted premolar teeth.

Materials And Methods: Forty non-carious, intact premolar teeth were selected and prepared with standardized Class V cavities.

A Comparative Evaluation of Contact Angle and Depth of Penetration of Sodium Hypochlorite With Various Surfactants: An In Vitro Study.

Objective: Sodium hypochlorite (NaOCl) is regarded as the most frequently used root canal irrigant. Its high surface tension prevents its penetration into complex canal anatomies. The present study assesses the contact angle and penetration depth of 2.

Platelet-rich fibrin in treatment of periapical lesions: a novel therapeutic option.

In the present case of a 35-year old patient, platelet-rich fibrin, which is an autologous platelet concentrate, was used to fill the osseous defect following surgery. The case was assessed both clinically and radiographically for a period of 9 months.

Supernumerary lateral incisor.

Supernumerary teeth are common in general population and occur frequently in patients with familial trait. However, it is rare to find supernumeraries in individuals with no associated disease or syndrome. Supernumerary teeth are found in any region of maxilla and mandible, with a predisposition for anterior maxilla.

Platelet rich fibrin: a new paradigm in periodontal regeneration.

Among the great challenges facing clinical research is the development of bioactive surgical additives regulating inflammation and increasing healing. Although the use of fibrin adhesives and platelet-rich plasma (PRP) is well documented, they have their own limitations. Hence, reconstructive dental surgeons are looking for an "edge" that jump starts the healing process to maximize predictability as well as the volume of regenerated bone.

Survival rates of porcelain laminate restoration based on different incisal preparation designs: An analysis.

Background: Veneer restorations provide a valid conservative alternative to complete coverage as they avoid aggressive dental preparation; thus, maintaining tooth structure. Initially, laminates were placed on the unprepared tooth surface. Although there is as yet no consensus as to whether or not teeth should be prepared for laminate veneers, currently, more conservative preparations have been advocated.

A comparative study of intra canal stress pattern in endodontically treated teeth with average sized canal diameter and reinforced wide canals with three different post systems using finite element analysis.

Study Methodology: THIS IS A COMPARATIVE STUDY OF INTRA CANAL STRESS PATTERNS IN ENDODONTICALLY TREATED MAXILLARY CENTRAL INCISOR WITH: average sized canal diameter and wide canals reinforced with three different post systems - cast post and core, carbon fiber post, stainless steel post; restored with ceramic crown using finite element analysis (FEA). All the models were subjected to a force of 100N applied at 450 to the long axis of the tooth at the middle third of the palatal surface of the restored ceramic crown.

Results: The FEA revealed that all the post systems showed maximum stress in the coronal and middle third of the root.

Nonsurgical endodontic treatment of type II dens invaginatus.

The endodontic treatment of teeth with dens invaginatus, characterized by an infolding of enamel and dentin, extending deep into the pulp cavity near the root apex, may be complicated and challenging. The complexity of the internal anatomy may create challenges for the complete removal of diseased pulpal tissue and the subsequent sealing of the canal system. Because of the bizarre root canal anatomy and widely open apex, a combination of nonsurgical and surgical endodontic treatment or extraction is the most common choice of therapy.

Finite element analysis of stress concentration in Class V restorations of four groups of restorative materials in mandibular premolar.

Aim: To study the concentration of stress in class V restoration of four different restorative materials subjected to occlusal load of 100N, 150N, 200N, 250N and to analyse the obtained data with the listed properties of the restorative material.

Materials And Methods: Using FEM analysis the stresses generated in a class V lesion in a mandibular premolar was studied.

Results: Within the framework of the aforementioned views, and from the results of the study it can be concluded that microfilled composite is the most suitable restorative material followed by flowable composite, glass ionomer cement and resin modified glass ionomer cement.
