The complete seating of full coronal restorations during cementation is hindered by the inability of cement to flow from the internal surface of the crown, and possible binding of the crown on the tooth. Perforation venting is an effective technique to allow full seating but requires repair of the perforation. Provision of space between the crown and the tooth for cement flow is also an effecti...

BACKGROUND Erbium, chromium: Yttrium, scandium, gallium, garnet (Er, Cr: YSGG) laser has been successfully used in the ablation of dental hard and soft tissues. It has been reported that this system is also useful for preparing tooth surfaces and etching, but no consensus exist in the literature regarding the advantage of lasers over conventional tooth preparation technique. MATERIALS AND MET...

STATEMENT OF PROBLEM Ideally, tooth preparation for complete crowns should require the removal of the smallest amount possible of sound tooth structure to maximize the strength of the remaining tooth. Some preparation designs, such as the feather-edge margin, are less invasive. However, limited data are available regarding monolithic lithium disilicate crowns for molars and premolars with this ...

Missing of mandibular second premolar is one of the most common types of tooth agenesis. In such cases, maintenance of the primary second molar, if possible at all, can prevent many treatment procedures in future. The present case report represents the endodontic management of a necrotic left mandibular primary second molar that had developed an abscess. Considering the missing of the permanent...

When treating the color of a single tooth in the esthetic zone, it is a complex task to achieve the same visual effect as the rest of the teeth. In addition to the problem of the clinical crown color, if the patient has a thin periodontal biotype it is necessary to manipulate both the hard and soft tissue to achieve a good esthetic result. To change the biotype, a connective tissue graft needs ...

Congenital absence of a maxillary lateral incisor occurs in many patients, and the treatment of young adults with this problem is a challenge for both prosthodontists and orthodontists. Common treatment alternatives are distalization of the canine tooth or fabrication of a conventional 3-unit fixed partial denture (FPD), a single-tooth, implantsupported crown restoration or a resinbonded fixed ...

Esthetic treatment of a single darkened tooth represents a great challenge to the dental practitioner. The properties of dental ceramic-colour stability, mechanical strength, clinical longevity, esthetic appearance and compatibility with periodontal tissues-make this material a good choice for such treatment. We present a case of restoration of a single, highly darkened anterior tooth with a fe...

The best plan for success is to begin with the end in mind. It generally is agreed that the successful treatment of a badly broken down tooth with pulpal disease depends not only good endodontic therapy, but also on good prosthetic reconstruction of the tooth after endodontic therapy. The primary purpose of the post is to retain a core that can be used to retain definitive prostheses. A post an...
