[Root-end filling materials. Proposal for a meta-analysis study].

BACKGROUND: The purpose of this study is to identify a first choice Root-end Filling Material (RFM) as regards the apical sealing ability. METHODS: The method we have used is the so called Metanalysis. It consists of the selection of all experimental studies already existing in literature and of the statistical processing of their results, so that it is possible to achieve a wider statistical sample which could lead to the most conclusive results. In this study we have tried to apply the above mentioned method to scientific articles investigating apical sealing ability through two different experimental methods: the dye penetration method and the fluid filtration method. RESULTS: This study shows that it is not possible to perform all the steps required for the realisation of a metanalytic study. This situation is consequential on the lack of well overlapped studies concerning the experimental protocol. We have tried, however, to outline the characteristics of main Root-end Filling Materials, on the basis of what we had achieved by consulting the single studies found in literature. CONCLUSIONS: It is necessary to carryout experiments consisting of more similar research protocols both to realise their metanalytic comparison and to respect one of the main foundations in scientific research, that is the effective repetition rather than a mere theoretical one.

[Platelet rich plasma (PRP): potentialities and techniques of extraction].

This paper describes the various techniques of platelet-rich plasma (PRP) extraction codified in recent years and their use potential is evaluated. PRP is one of the techniques with which at the moment it is attempted to modulate and facilitate the cure of a wound. The use of PRP is based on the theoretical premise that by concentrating platelets the effects of the growth factors (PDGF, TGF-beta, IGF-I and -II) so released will be increased. Marx's original technique is described above all. This prescribes the sampling of a unit of blood (450-500 ml) and the use of a cell separator. We then analysed the technique of Marx and Hannon in which the quantity of blood sampled is reduced to 150 ml, and the two simplified techniques of the Sacchi and Bellanda group. Finally, a new PRP extraction technique is described. We conclude that platelet gel allows access to autologous growth factors which by definition are neither toxic nor immunogenic and are capable of accelerating the normal processes of bone regeneration. PRP can thus be considered a useful instrument for increasing the quality and final quantity of regenerated bone in oral and maxillo-facial surgery operations.

[Cyst and pseudocyst of oral maxillo-facial region. Clinical and therapeutical considerations].

Oral and maxillo-facial cysts are very common lesions that show different clinical and pathological aspects. The surgical treatment of these lesions is conditioned by many factors such as the lesion dimension, the involvement of vascular and neurological structures, the presence of recoverable teeth into the cyctic area, the conditions of the patient. For these reasons surgical treatment guidelines may greatly diverge in the various cases. There are three different kinds of treatment: cystotomy (Partsch I), cystectomy (Partsch II) and a combination of the two reported surgical treatments: at first Partsch I and in a second time Partsch II. The authors present two cases of maxillo-facial cysts that are characterized by different clinical aspects: a follicular cyst in a male, nine years old, and a retention cyst located in the tongue of a young female. Follicular cyst is a very common lesion of maxillary bones related to an impacted tooth; retention cyst is a rare soft tissue pathology. The analysis of these so different cases permits to formulate many interesting observations about the main aspects of diagnosis, treatment and management of patients affected by maxillo-facial cysts.
