[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.

Esthetic principles in prosthetic dentistry.

Dento-facial esthetics represents today the fourth clinical dimension in our activity. Together with morphological, functional and biomechanical factors, aesthetics contribute to a successful clinical result in prosthodontics. Dento-facial esthetics takes over the visual perception principles adapting them to dental requirements. Continuously assimilating esthetics information, being a good observer and training visual perception is important for the final complete result in prosthetic dentistry.

[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.

[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.

[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.

[Communication and iatrogenesis through communication].

Human intercommunication means transfer of information through many channels, with codes that have biological and socio-cultural determinism. The biological determinism is identifiable through the development of the phonetics and ergomotricity functions, through the possibility of perception of the sensorial organs. The channels of human intercommunication can be verbal, linguistic (the most specialised channel), and nonverbal, extra linguistic channels (mimics, written model, drawing, walking), that are effectively implicated in defining a direct dialogue between the doctor and the patient, completing and emphasising the communication.

[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.

[The stomatognathic electromyographic aspects in spasmophilia].

The study intends to statuate the theoretical foundations concerning the etiopathogenesis (of endocrinological origin--tetany) of the myofacial pain dysfunction (MPD). We want to demonstrate this affirmation knowing that there is a very important correlation between the endocrine glands and the muscular stomatognathic activity. The EMG exam in tetany for the masticatory muscles proves that there is a repetitive asymmetric bioelectric activity even for the rest positions.

[Occlusal rehabilitation under conditions of the simulation of averages].

The Fag articulator is an anatomical and semi-adaptable one, light and with a supple, stable and rigid mechanism of manipulation and an easy access to the models. These characteristics make it more sensitive in all situations of occlusal rehabilitation. The articular system permits the exactness mechanical reproduction of the fundamental movements of the mandible, with the possibility to reproduce the characteristics of the lateral movements (angle Benett adjustable), protrusion and variable inclinations of the condylar slope. The employment of this articulator in the dentistry practice allowed us to obtain a functional occlusal rehabilitation in all types of edentulous and we avoided the premature occlusal contacts.
