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...

AIM To compare the retention of amalgam restorations in bonded amalgam restoration and restorations with undercuts. BACKGROUND With improvement in adhesive technology problem associated with conventional preparation for amalgam restorations mainly compromised resistance form of tooth structure have been largely overcome. MATERIALS AND METHODS Forty caries free extracted molars were used. A ...

Sudden tooth loss in the esthetic zone of the maxillary or mandibular anterior region can be due to trauma, periodontal disease, or endodontic failure. The treatment options for replacing the missing tooth can vary between removable prosthesis, tooth-supported prosthesis, and implant-supported prosthesis. Irrespective of the final treatment, the first line of management would be to provisionall...

Background Bonded indirect restorations are laboratory fabricated and requires at least two appointments: one for provisionalization and one for luting. In the first appointment, an impression is immediately taken after tooth preparation, followed by a provisional treatment, which traditionally consists of luting a temporary restoration. After the indirect restoration fabrication, the temporary...

The ultimate goal for an esthetic rehabilitation is the restoration of health, beauty, and function to the patient. This article illustrates a predictable system to guide the clinician with tooth preparations for porcelain veneer restorations based upon the additive diagnostic wax-up. This system promotes a preparation technique using a series of guides that direct the clinician to reduce only ...

Iatrogenic perforation of the furcation area in multi-rooted molars during preparation of the access cavity can potentially lead to tooth extraction. The present case report describes the nonsurgical endodontic management of an extensive pulp chamber floor perforation in a first mandibular molar with calcium enriched mixture (CEM) cement. The perforation was chemically cleaned and then physical...

Conservative instrumentation of initial posterior approximal caries is beneficial to patients and simplifies surgical management. This article describes a minimally invasive technique for preparing Class II lesions while keeping the marginal ridge and occlusal surface intact. Eradication of caries by minimally invasive techniques and restoration of tooth form after such cavity preparation neces...

Traumatized teeth can bleed internally, causing discoloration over time. When this occurs in the smile zone, masking the dark colorations can present challenges when attempting to practice conservative cosmetic dentistry. Implementing nonvital bleaching can significantly improve the dark colorations of the traumatized teeth and support very conservative cosmetic dentistry. Effective communicati...

ackground and aim: it is important to evaluate the effect of the type of filling material on deformation and strength of tooth after filling and also the effect of filling depth on quality of restoration of a decayed tooth. material and methods: the orthopantomogram (opg) of the first and second molars of a 28-year-old man was made and the teeth were 3d modeled. the stress-deformation analysis ...

In attempting to provide a restorative solution for cases that have been compromised by spatial considerations, clinicians have traditionally opted for an orthodontic approach that did not provide optimal aesthetics due to changes in tooth morphology, specifically tooth size and shape as a result of dental deterioration. With the advent of contemporary aesthetic materials and preparation techni...
