The durability of amalgams in primary molars was examined retrospectively using an audit of the records of 226 pediatric dental patients attending a dental school clinic. Individual amalgam histories were followed for up to 9 years, computerized, and durability assessed in terms of amalgam replacements and length of service, using compu ter-appropriate definitions for failure and success. The r...

BACKGROUND AND AIMS Retreatment of existing restorations not only requires a lot of money and time but also there is a danger of weakening tooth structure and irritating the pulp. Since awareness of the reasons for the retreatment of teeth will save the teeth from possible future failure, the aim of this study was to assess the reasons for retreatment of amalgam and composite restorations in pa...

Dental treatment procedures are increasingly governed by factors such as biocompatibility of restorative materials, patients demands for esthetics and a conservative approach to minimize loss of tooth structure.G.V Black was the first person to describe the ideal cavity form to restore carious lesions. G.V Black followed “EXTENTION FOR PREVENTION” as ideal principle for cavity preparation.Such ...

This study determined the validity of marginal ditching and staining as criteria for the diagnosis of secondary caries around amalgam restorations. One hundred and twenty-four Class I amalgam restorations on extracted human teeth were submitted to standardized clinical examinations. A calibrated examiner recorded the presence of ditching in the tooth/restoration interface, the occurrence of blu...

The aim of this study was to compare the clinical performance of an amalgam, a glass polyalkenoate (ionomer) cerment material and a resin-based composite material used in small Class II cavities in permanent teeth. All restorations were inserted under rubber dam. They were examined yearly for 3 years. One clinician continued the study up to 5 years. The clinical examination focused on two crite...

Aims: The aim of this study is to determine the effectiveness of mandibular infiltration compared with the mandibular block in treating mandibular primary molars in children and to relate it to the type of treatment performed. Materials and Methods: The study design was case control study. The study sample consisted of 98 cooperative children of age 3-9 years old. Forty eight children were the ...

This study evaluated the influence of the pulp protection technique on clinical performance of amalgam restorations after three years, with particular reference to post-operative sensitivity and secondary caries. One hundred and twenty (120) Class II amalgam restorations (68 premolars, 52 molars; 78 MOD, 42 OD/MO) were placed in 30 participants (four restorations per participant). The restorati...

PURPOSE Traditionally, resin composite restorations are claimed by reviews of the dental literature as being superior to glass-ionomer fillings in terms of restoration failures in posterior permanent teeth. The aim of this systematic review is to answer the clinical question, whether conventional high-viscosity glass-ionomer restorations, in patients with single and/or multi-surface cavities in...

An in vitro study was conducted to determine the adaptation of composite resin restorative material to rounded and acute-angled retention grooves of Class I cavity preparations on 24 extracted premolars. Two chemically cured (P-IO ® and Miradapt ®) and 2 light-cured (Prisma-Fil ® and FulFil ®) composite resin materials, after being coded to create a blind study, were injected into cavity prepar...

In a clinical trial, 1544 Class II amalgam restorations were inserted. In this study 1213 restorations were evaluated after 15 years and the reasons for replacement were registered. Attention was also paid to patient drop-out and patients' variables such as gender, filling degree, type of tooth (premolar vs molar), type of restoration (MO or DO vs MOD), jaw (upper vs lower) and the patients' op...
