Clinical Effects of Mercury in Conservative Dentistry: A Systematic Review, Meta-Analysis, and Trial Sequential Analysis of Randomized Controlled Trials

TLDR
There are not enough data to support the hypothesis that restorations with dental amalgam can cause nephrotoxicity when compared with composite resins restoration, according to the existing evidence.

[The long-term results of teeth restoration with composite resin materials: a systematic literature review].

TLDR
It is suggested that composite resin restorations can demonstrate clinically acceptable results in the long-term period and the main risk factors of failure are smoking, beverages consumption, bruxism, xerostomia and low level of caries resistance.

Trend of posterior teeth restoration at ibadan, Nigeria.

TLDR
The use of amalgam as choice material for restoration of posterior teeth is gradually being replaced by composite in the authors' environment which emphasizes the need to ensure the quality and durability of the composites used.

Success rates of manual restorative treatment (MRT) with amalgam in permanent teeth in high caries-risk Filipino children

TLDR
Manual restorative treatment (MRT) amalgam restorations were performed satisfactorily, but higher dental caries experience and large cavities contribute to lower success rates.

Restorative Direct Management of Cavitated Proximal Carious Lesions of Permanent Molars using Elastic Separators in Children and Adolescents

TLDR
Restorative management of cavitated proximal carious surfaces of permanent teeth with amalgam or composite resin, using elastic separators, seems to be a very good and promising alternative technique in the context of the minimal invasive dentistry in children and adolescents.

of posterior restorations: A systematic review and meta-analysis

TLDR
A systematic review and meta-analysis of clinical trials and prospective and retrospective studies comparing the failures rates between occlusal andocclusoproximal amalgam and composite resin posterior restorations found no difference.

COMPARATIVE STUDY BETWEEN THE EFFECT OF CLASS II AMALGAM AND COMPOSITE RESTORATIONS IN POSTERIOR TEETH ON PERIODONTAL TISSUES HEALTH

TLDR
Class II composite restorations appear to be associated with periodontal breakdown more than class II amalgam restoration, while there is no statistically significant decrease in GI, PPD and CAL scores between both groups.

Practice-based analysis of direct posterior dental restorations performed in a public health service: Retrospective long-term survival in Brazil

The aim of this retrospective study was to evaluate the survival and associated factors for the longevity of direct posterior restorations and to verify whether the geographic location of public

Analysis of Composite Resin Treatment Pattern Changes After the Insurance Coverage

TLDR
There was a significant change in frequency of resin restoration by shape of cavity comparing before and after the insurance coverage, whereas there was no significant difference in changes by patient age, gender and position of tooth.

Survival and reasons for failure of amalgam versus composite posterior restorations placed in a randomized clinical trial.

TLDR
Use of amalgam appears to be preferable to use of composites in multisurface restorations of large posterior teeth if longevity is the primary criterion in material selection.

The longevity of amalgam versus compomer/composite restorations in posterior primary and permanent teeth: findings From the New England Children's Amalgam Trial.

TLDR
Although the overall difference in longevity was not statistically significant, compomer was replaced significantly more frequently owing to recurrent caries, and composite restorations required seven times as many repairs as did amalgam restorATIONS.
