Root surface caries: a critical literature review.

Little information is available on the prevalence and clinical appearance of root surface caries. The literature shows that root surface caries is thought to be similar to coronal caries, but that certain diet-bacterial interactions might predispose to root surface caries. A scan of the literature concerning the epidemiology, etiology, microbiology, periodontology, as well as reporting methods and restoration treatment of root surface caries shows current practices and suggests future research.

[Comparative scanning electron microscopic studies on the width of the marginal cleft of various composites and on the accuracy of reproduction of the clefts with various casting materials]. / Vergleichende rasterelektronenmikroskopische Untersuchungen über die Randspaltbreite verschiedener Composites und über die diesbezügliche Wiedergabegenauigkeit underschiedlicher Replicas.

Poor results concerning the formation of marginal clefts were obtained with Adaptic and Concise; all composites utilizing the etching technique showed a homogeneous transition between enamel and filling. It should be noted that our findings were taken from extracted teeth 24 hours after the filling. No statement therefore can be made about the long-term behavior of these filling materials in the mouth.

[Experimental studies on the accuracy of replicas in the manufacture of crowns from composites]. / Experimentelle Untersuchungen über die Wiedergabegenauigkeit von Replicas bei Kronenaufbauten mit Composites.

Various replica models were studied in terms of surface-profile measurements and with scanning electron microscopy in the context of a continuous in vivo study of composite restoration. After taking an impression with a gum-elastic impression material, Araldit replicas, of all models tested, proved to be the most accurate.

[The importance of detailed findings within the framework of identification]. / Uber die Bedeutung von Detailbefunden im Rahmen der Identifizierung.

Examples were presented to show that oral findings with the many individual characteristis are extremely valuable for the forensic pathologist and may often furnish crucial information for identifying unknown persons. Recording and evaluation of oral findings therefore should be carried out by an experienced dentist who, should the need arise, can also advise the forensic pathologist. Unfortunately, there is little interest at present for these problems in the field of dentistry.
