[Cephalometric changes in acromegaly].
Acromegaly represents the endocrine disease which includes the somatic and metabolic disorders secondly resulting to the augmentation of the Growth Hormone secretion after the growth cartilages closing (in adult). In this case we can find very important troubles which characterize all the specific elements of the stomatognathic system. The cranio-facial skeleton has a specific configuration, the mandible is developed in excess and the relationships between the maxilla, the mandible and the skull are strongly modified. These and the structural bony troubles, the bony asymmetries involve periodontal, muscular and articular disturbances. In this study we want to describe the craniofacial cephalometric qualitative and quantitative disorders and to emphasize their implications in the onset and the evolution of the stomatognathic system dysfunctional syndrome.

Peri-implant tissue and the longevity of restoration.
The clinical success was analysed several times, based upon the good results obtained and unfortunately not on a basis of correct scientific researches, as the cellular and ultrastructural investigations. In the randomized study a more numerous failures are seen in the first, respectively second year, after the application of the implant. The failures were predominantly observed in case of mandible implants. The quality of the bone is an essential factor for the success of the implant without correlation with the age of the patient. The most objective choice of the patients as well as a correct conceived and executed therapeutical plan, the follow-up cooperation with the patient, in what concerns the strict oral hygiene, would had to an increasing number of successfully solved cases. The success of the implant may be ensured when besides the content of the patient, the long-term stability of the soft and bone peri-implant tissues is achieved. By this is also obtained by morphological stability, which may be evaluated following clinical X-ray parameters. This stability is under dependence of the biological status. Conclusively this means an established biomechanical balance and stable relationships between the immune defense system of the least and the pathogenic potential of the microorganisms.

Peri-implantitis.
Peri-implant lesions are directly linked to the relationship between the implant and the soft tissue. These lesions are rare in the case of pure Ti smooth implants, but appear frequently around the rough-surfaced implants. A marginal inflammation may result in a rapid peri-implant bone loss, since the peri-implant connective tissue constitutes in a less effective barrier than the same tissue surrounding the tooth. The morphopathological examination of the peri-implant tissues revealed after their removal that the gum's mucous membrane is not inflamed, but degenerative lesions were observed both on the epithelium and chorion. The papillary lamina propria contains few cells, but it is rich in collagen fibers; vasodilatation and edema were also present. Multiple areas of lysis of the intercellular junctions were also observed at the intermediary level of the gum peri-implant epithelium (the epithelial cells undergo a process of involution at the intermediary level of the epithelium). Important changes can be seen both at the level of intercellular junction systems and at the junction between the basal extremity of the epithelial cells and the basal membrane.

[The terminal occlusal contacts of the edentulous patient with a complete denture].
For the last few decades our knowledge concerning the occlusion have developed a lot, because of the many clinical, morphological and functional implications of the occlusion. In the study of the terminal occlusion, it is considered to be of functional importance the closing trajectory of the mandible in centric relation and the closing trajectory of the mandible in maximal occlusion. The purpose of this research is to analyse the terminal occlusion of the complete denture patients, emphasize the link between occlusion disharmony and instability of the complete denture. Complementary exam used is the computerized T-scan system connected a compatible IBM computer. The study included 17 to subjects (11 males and 6 females), with an age over-age of 63 years. When completing this study the authors were able to classify four types of occlusal contacts.

[The correlations between the electromyographic display and the aspects involved with masticatory muscle contraction and phosphorus-calcium metabolism].
The neuromuscular activity at the level of the stomatognathic system has a specific complexity, due to the multiple systemic functions, realizing the statistical and dynamical mandibular positions and the integration of the stomatognathic system at the level of the human body. Knowing that the neuroendocrine system represents an important factor for the over-systemic coordination of the stomatognathic muscular activity, we want to establish the implication and the neuroendocrine correlation in the stomatognathic muscular dysfunctions determined by some endocrine diseases.

[Changes in the craniomandibular relations of acromegaly patients].
The dishomeostazical theory (etiopathogenic integrative concept) allows an ample and complex vue on the stomatognathic system dysfunctional syndrome, because it begins from the perception of the stomatognathic system (SS) as a whole in which the alteration of each element can induce the disfunction of the entire system. The purpose of this study is to demonstrate that the neuroendocrine suprasystemic factor (STH hypersecretion on adult organism) disturbs every element of the SS and induces an important alteration of the fundamental cranio-mandibular relations.

[A statistical analysis of the variation in the cephalometric measures of acromegaly patients].
Acromegaly represents the endocrine disease which includes the somatic and metabolic disorders secondly resulting to the augmentation of the Growth Hormone secretion after the growth cartilages closing (in adult). In this study we want to describe the craniofacial cephalometric qualitative and quantitative disorders and to emphasize their implications in the onset and the evolution of the stomatognathic system dysfunctional syndrome. For proving this things, we made a statistical study using a statistics function named "standard deviation" which is a measure of how widely values are dispersed from the average value.

[Periodontal regeneration with enamel derivate proteins (Emdogain)--clinical evaluation].
UNLABELLED: The study was undertaken in order to evaluate the effect of Emdogain as an adjuvant in periodontal surgery in promoting bone level gain, compared to bone levels after surgery. METHOD: The study was realised on 6 patients. who had pair test sites and control sites. Two interproximal sites were selected in each patient at a distance from each other, in the same maxilla, with infra-osseous defects with depth > or = 4 mm and width > or = 2 mm. The patients were followed on a long term period, initially and after 8 and 16 months. RESULTS: The average values of the clinical attachment level were evaluated both in the test sites and in the control group at 8 months and 16 months, The radiographic osseous level continued to recede at the group treated with Emdogain, and in the control group it remained at its initial level. The radiographic gain was ascertained after 16 months. CONCLUSION: This study proves that the topic use of Emdogain as an adjuvant, during periodontal defects surgery, on radicular surfaces, determines a gain in the clinical attachment and an osseous gain observed on X-rays.

[The para-clinic investigation of temporo-mandibular joint changes in patients with acromegaly].
The Acromegaly is an endocrinological disease determined by the hypersecretion of STH in a certain period of the body evolution and it causes the hypertrophy of bones in general and of mandible and cranio-facial bones, determining a disorder due to this development of bones, associated with troubles in the activity of muscles and of the phospho-calcium metabolism. This study was made on a group of 33 acromegaly patients. Their temporo-mandibular joint was investigated by ortopantomography, tomography, computer tomography and scintigraphy. All of these exams shows the changes in temporo-mandibular joint due to the cells hyperactivity determined by the hypersecretion of STH.

[Some aspects concerning the electrochemical corrosion of the Gaudent-S dental alloy].
The potentiodynamic polarization methods have been employed to evaluate the corrosion resistance of the Gaudent-S dental alloy in a slightly acid artificial saliva (Fusayama's saliva; pH = 6.18), a slightly alkaline artificial saliva (Rondelli's saliva; pH = 7.75) and in an acid saline solution (NaCl/lactic acid; pH = 2.64). The results were compared with those obtained for copper and aluminium--the principal components of the studied alloy. In Fusayama's artificial saliva both the copper and Gaudent alloy exhibit close indentic cyclic voltammograms, typical for pitting corrosion; the pitting potentials being 1550 mV (SCE) for Gaudent-S and 1350 mV (SCE) for copper, while the repassivation potential is 700 mV (SCE), the same for the two analysed metals. In the Rondelli's artificial saliva and in acidic saline solution the passivation domain is considerable reduced; the corrosion potential and the repassivation potential coincides. In the saline acid solution the current densities are two times higher than those obtained in the other two solutions. In the aluminium case it can be noticed that the passivation domain is very reduced, no cathodic peak is observed and much more current densities are registered in the positive potential domain.

[Correlations between occlusal dysfunctions and temporomandibular joint disorders].
The occlusal problems and the temporomandibular disorders are the most frequent aspects which we often find to the patients with the dysfunctional syndrome of the stomatognathic system. This study tries to establish the correlation between these two kinds of dysfunctions and to find (if it exists) a direct proportional relation between them. For this purpose we studied 8 cases who had been diagnosed as having the dysfunctional syndrome of the stomatognathic system on the base of the clinical symptoms, tomographs and CT. The results of the study proved that an occlusal dysfunction can affect the temporomandibular joint and vice versa, because all the component parts of the stomatognathic system are in a close relationship and they influence each other, but these results didn't indicate a direct proportional relation between these two kinds of dysfunctions.

[The evaluation of sound level in dental practice].
Noise pollution is one of the most important problems of the contemporary world. Dentistry is one of the most affected areas because the activity in a dental practice involves the use of different devices that generate noise. The purpose of our study is to evaluate the sound level in a dental practice with 4 dental units using a complex system, which comprises: a Sound Blaster Live 5.1, a Dual microphone, a PC and special software for the acquisition and data analysis. The sound level detected by us is similar with the data from the international literature with some particular aspects and suggests that the dental practice is a noise polluted environment although most of the sound levels are beneath the damaging noise level for the human ear (85 dB).

Morphological features in the embryological development of the anterior arch of the mandible.
OBJECTIVES: Our study is focused on the typical morphological features of the development of the mandible. There were investigated both specific elements for the ossification process as well as aspects of the developing tooth germs. METHODS: We performed transmission electron microscopy analyses on sections obtained from 15 human embryos aged between 6 and 20 weeks. The sections were acquired from specific areas of the anterior arch of the mandible, corresponding to the sites of development of the tooth germs, namely the incisors and the canines. RESULTS: There were observed some characteristic elements for the intramembranous ossification process (mesenchymal cells, collagen fibers, osteoblasts, bony spicules), and for the different stages of odontogenesis (bud, cap). CONCLUSIONS: The results confirm the important role of this territory and highlight the primary elements of the intramembranous ossification and of the odontogenesis, as essential steps in the development of the head and the face.
