A hundred and fifty patients with drug-controlled diabetes mellitus complaining for xerostomia were examined, in order to evaluate the incidence of xerostomia with sex, duration of the disease and recent value of blood glucose. Xerostomia was recorded in 76% of the patients with a predilection for women (50.87%). Finally, the incidence of xerostomia was not related with duration of the disease and recent value of blood glucose.

It is well known that Prosthetics is the part of Dentistry that needs the dentist's and D. technician's cooperation in order to be completed. For this reason the aim of our research was on one hand to record the planning and the kinds for the fixed bridge work that proceed from the cooperation of the two sides and on the other hand to evaluate the results, to locate the weak points and to give the possibility to our department to obtain clearer and more entire of the Prosthetic treatment given by the dentists and D. technicians. So from this research and the answers to the four sections which refer to the above mentioned subject, we had some information about the plannings and the kinds of the crowns, the way of their forwarding the importance of the aesthetic part of the constructions and at last the problems which are created on the dental laboratories by the way which the teeth are prepared.

A review of the literature on elastomeric impression materials, is presented in this paper. The article mentions the composition and the most important properties of the elastomeric impression materials used in dental practice. The clinical significance of these materials, physical and mechanical properties are also emphasized. In addition some new elastomeric impression materials with improved properties and a new (experimental) light-cured impression material, are mentioned. Another part of this article is the biocompatibility of these materials. In the end the great significance of handling is outlined.

The causal therapy of skeletal Class II anomaly consists of the changes of the jaws' relationships to each other during the growth of the craniofacial complex. A plenty of orthodontic appliances are employed, the effectiveness of which remain debatable. This paper attempts to compare the three main orthodontic appliances used in our clinic: activator, headgear and combined headgear activator. Patients with a skeletal Class II anomaly at the beginning of treatment were studied with two different types of cephalometric analysis. The lateral X-ray head films were carried out directly before and after treatment. In this study the growth pattern of the patients' craniofacial complex has been seriously taken into consideration. Following conclusions are to be taken: The initial skeletal Class II anomaly as well as the orthodontic appliances have to be differentially evaluated by the treatment planning. The isolated changes are often not great, but taken as a whole, they attain to correct the existing anomaly. The annual rates of the jaws' length depends not only on the age, the sex and the duration of orthodontic treatment, but also on the growth pattern of the craniofacial complex and the particularities of treatment methods. In order to achieve the therapeutic aims all these factors are to be considered for the treatment planning.

There is a growing interest in the oral health status of older persons 65+ years as the size of this population increases and the percentage of edentulous persons decreases as a result of the prevention in younger ages. The provision of dental care in the elderly patient is basically the same as the care provided to other segments of the population. Yet there are problems related to their mental and physical health which should be taken into account. In this paper some information was given about the dental caries, periodontal diseases, oral mucosa diseases and tooth loss in the elderly population as well as about the dental treatment and prevention of dental services and the factors that affect it are referred. Further, some recommendations for the improvement of oral health of the elderly in Greece were done.

The authors describe the procedure followed in the identification of a corpse by means of findings gathered from periapical X-rays. The interesting point about this identification is that it was practically based on one single tooth; The dental periapical X-rays of the person to which the body was suspected to belong, revealed certain peculiarities in the root outline and the endodontic treatment of an upper second right premolar. An X-ray of the corresponding tooth of the corpse was taken and the same identical findings were seen, thus documenting the identity of the corpse.

Prosthetic treatment of endodontically treated teeth usually involves the use of pins, prefabricated or cast posts that basically aim to protect the tooth from horizontal or vertical fractures. Nevertheless, according to the current way of thinking, the most important factors against tooth fractures are the preservation of as much as possible sound tooth structure as well as the use of full coverage. The amalgam coronal-radicular dowel and core technique is described in this paper. The method has been tested successfully in recent studies, both in vitro and in vivo. Its advantages are that it requires less sound tooth structure removal, involves uniform material for both the dowel and the core, is accomplished in a single chair side session and can be easily removed. It can accordingly be used as a complete crown build up in cases where prosthetic treatment has to be postponed for various reasons.

A large number of the all operative work performed in a dental office is amalgam fillings. Secondary caries continuous to be a serious problem although amalgam has been improved to a large extent. All efforts that have been made to eliminate the problem of secondary caries associated with amalgam fillings have not been very successful so far. There is always a lack of permanent seal between restorations and the prepared tooth surfaces so that microleakage always exists. The purpose of this paper was to search the literature on the subject and find ways and attempts that have been made on the elimination of secondary caries. On the other hand was aimed to present and discuss the application of fluorides into the cavity preparation as a preventive method of eliminating secondary caries as well as the possible effects of fluorides on the dental pulp if they exist. The literature gives a lot of information on the subject and fluorides in the cavity before the filling insertion seems to be a safe and approved method against secondary caries. Regarding the effect of fluorides on the pulp it is indicated that when the proper agent and technique is used there is no any deleterious effect and the method is not contraindicated.

In this paper, the efficacy of tissue conditioning treating stomatitis caused by dentures, was examined. It was found that 96.6% of the cases treated by this method were cured and the highest curative result was noted after a fifteen days period. Sex did not affect the curative result. The persistence of using tissue conditioning, for a period longer than four weeks, is in vain.
