Specific microRNA (miRNA) expression profiles have been reported to be predictive of specific clinical outcomes of dental implants and might be used as biomarkers in implant dentistry with diagnostic and prognostic purposes. The aim of the present narrative review was to summarize current knowledge regarding the use of miRNAs in implant dentistry. The authors attempted to identify all available evidence on the topic and critically appraise it in order to lay the foundation for the development of further research oriented towards the clinical application of miRNAs in implant dentistry.

The evaluation of defense mechanisms represents one of the most promising fields in the psychodynamic-oriented empirical research on personality disorders (PDs). This study examines the association between DSM-IV PDs and defense mechanisms. We evaluated a sample of 50 adult outpatients seeking personality assessment and psychotherapeutic treatment. PDs have been assessed using the Structured Clinical Interview for DSM-IV Personality Disorder, version 2.0. Defense mechanisms have been evaluated by a group of trained clinical psychologists and psychiatrists (interrater reliability from .61 to .95) using Perry's Defense Mechanism Rating Scale. Our results support the hypothesis that some defense mechanisms underlie PDs and that defenses call for further attention as we assess PDs.
