MTA versus Ca(OH)2 in apexification of non-vital immature permanent teeth: a randomized clinical trial comparison.

Objectives: The aim of this prospective randomized clinical trial was to compare mineral trioxide aggregate (MTA) with calcium hydroxide (CH) as materials for inducing root apex closure in immature necrotic permanent incisors.

Methods: The design of this study has been extensively described in the authors' previous report. Children (n = 30), aged from 6 to 18 years and presenting a non-vital permanent incisor, were treated.

Outcome of endodontic treatments made by postgraduate students in the dental clinic of bretonneau hospital.

Objective. The objective of this retrospective study is double: (1) to assess the 1-4 years of outcome of endodontic treatment performed by postgraduate students in endodontics in the Dental Clinic of Bretonneau Hospital and (2) to examine outcome predictors. Method.

Minimal intervention dentistry II: part 4. Minimal intervention techniques of preparation and adhesive restorations. The contribution of the sono-abrasive techniques.

The concept of minimal intervention in oral medicine is based on advances in biological sciences applied to the dental organ. Many cultural barriers, economic as well as technical, have thwarted the application of micro-invasive conservative techniques by the general practitioner. Emerging technologies do not remove all obstacles but promote the integration of less invasive techniques in daily practice.

Management of internal root resorption on permanent teeth.

Internal root resorption (IRR) is a particular category of pulp disease characterized by the loss of dentine as a result of the action of clastic cells stimulated by pulpal inflammation. This review article explains the etiology, the prevalence of IRR, and, in addition to the clinical data, the contribution of the three-dimensional imaging (CBCT) to the diagnosis, the clinical decision, and the therapeutic management of IRR. The authors discussed the various therapeutic options including the orthograde or retrograde fillings of the root canal resorption area.

Minimal intervention dentistry: part 6. Caries inhibition by resin infiltration.

Resin infiltration has made possible an innovative way of treating initial carious lesions that fits perfectly with the concept of minimal intervention dentistry. Infiltration of carious lesions represents a new approach to the treatment of non-cavitated lesions of proximal and smooth surfaces of deciduous and permanent teeth. The major advantage of this method is that it is a non-invasive treatment, preserving tooth structure and that it can be achieved in a single visit.
