[Investigations on the prevalence of headache associated with mandibular dysfunction]. / Badania nad czestoscia wystepowania bólów glowy zwiazanych z dysfunkcja ukladu ruchowego narzadu zucia.

The role of mandibular dysfunction in the etiology of headache is still underestimated in the medical literature. For this reason an analysis of own questionnaire investigations published in the years 1983 to 1999 was done. These investigations were carried out in 3915 subjects aged 15-66. In order to determine the prevalence of headache associated with mandibular dysfunction in the analysis mandibular parafunctions and clicking in the temporomandibular joints (TMJs) were selected. The comparison of the prevalence of headache in groups with and without mandibular parafunctions and in groups with and without clicking in the TMJs has shown that the prevalence of headache was significantly higher in groups with mandibular parafunctions and with clicking in the TMJs than in groups without these disturbances. The difference in the prevalence of headache in the investigated groups has shown that headaches noted in the population can be associated with mandibular parafunctions in 18.2% and dependent on the age with clicking in the TMJs in 9.7% to 25%.

Recording centric and eccentric occlusal disturbances with a new recording device.

A recording device termed a "Kleinrok Functiograph" was introduced to simultaneously document condylar- and tooth-guided mandibular movements on the same plate. The Functiograph instrument permitted objective monitoring of mandibular movement without tooth contact, with all tooth contacts, and allowed analysis of the correlation of these two recordings. After 10 years of conducting investigations on centric occlusion using the Functiograph instrument combined with clinical, radiographic, and electromyographic studies, it was possible to differentiate the horizontal Functiograph recordings of normal and disturbed centric occlusion at a clinically acceptable vertical dimension. Two types of centric occlusal disturbances were classified to accelerate diagnosis and standardize communication.

[Eye signs in patients with functional disturbances of the stomatognathic system]. / Objawy oczne u chorych z zaburzeniami czynnosciowymi ukladu ruchowego narzadu zucia.

The authors carried out an analysis of the frequency of eye signs in 429 patients with functional disturbances of the stomatognathic system and found that these disturbances were present in 29.8% of these patients, and the intensity of eye signs depended on the clinical picture of dysfunction. Return of normal function of the stomatognathic system gave complete regression of eye signs in 66.7% out of 36 patients, in 30.5% of cases improvement developed, and in 2.8% local stomatological treatment was unsuccessful.

[A new recording set for the arrangement in the intra-oral sagittal angle. Remarks to a discussion of the article by K.P. Schlössler and A. Vogel, in Stomato. DDR 37 (1987) 660-663]. / Ein neues Registrierset zur intraoralen Pfeilwinkelaufzeichnung. Diskussionsbemerkungen zur Arbeit von K.P. Schlössler und A. Vogel, in Stomatol. DDR 37 (1987) 660-663.

The authors of the article did not present the "Functiograph according to Kleinrok" as well as the method of intra-oral mandibular movement recording according to Kleinrok in a clear way. For this reason the construction of this recording device as well as above mentioned method as described.

Investigations on prevalence and treatment of fingernail biting.

Numerous investigations indicate that there is a parallel between emotional stress and hyperactivity of the masticatory muscles connected with mandibular parafunctions. Elimination of mandibular parafunctions is difficult and almost impossible, therefore, this paper proposed a treatment whereby nonharmful motor habits are substituted for the parafunction. Questionnaire investigations were carried out in 2905 subjects, with an attempt at treatment in the youngest group of 222 pupils. It was found that good results were obtained through adult supervision and cooperation.

[Justification of the needs and a trial of establishing of the principles of prophylaxis of functional disturbances in the stomatognathic system]. / Uzasadnienie potrzeby i próba ustalenia zasad zapobiegania zaburzeniom czynnosciowym narzadu zucia.

The author indicates a dramatic rise in the number of patients with signs of dysfunction of the masticatory system which are one of the main social problems in modern stomatology. Including of dysfunction signs into the range of periodic stomatological examinations is postulated, and the principles of prevention of these disturbances are described. For the realisation of these aims it would be indicated to organize special scientific units, to introduce proper training of students and dentists as well as medical students, and to set up specialization in this branch of stomatology. In the treatment, especially in cases complicated with headaches and pain of the eyes, ears, spine and muscles in the vicinity, and with trigeminal neuralgia, a far reaching cooperation is needed of highly specialized stomatologists with the specialists from other branches of medicine.

[Studies on the incidence and possibility of collective treatment of certain non-occlusal parafunctions in elementary school children]. / Badania nad czestoscia wystepowania i mozliwoscia zbiorowego leczenia wybranych parafunkcji niezwarciowych u uczniow szkoly podstawowej.

A study was carried out on the incidence and possibility of collective treatment of non-occlusal parafunctions in 216 elementary school children aged 7-14 years. Two objectively detectable non-occlusal parafunctions were analysed: nail-biting and pencil-biting. The study included four meetings during which the fingernails and pencils were inspected in all children and a talk was given, explaining the harmfulness of motor habits in the masticatory system, and the children with these habits were told to replace them with other non-harmful movements as habits. Among 216 children 131 (60.6%) had such non-occlusal parafunctions with nail-biting in 51.9% of them, and pencil-biting in 31%. In 22.2% both habits were found. During the third control visit the overall incidence of both parafunctions was found to be decreased, from 60.6% to 37.9%. Elimination of nail-biting was obtained in 37.5% of cases, and pencil-biting in 64.2%, with the proportions of treated children varying in various classes. The study showed that nail-biting and pencil-biting are widely spread habits in the studied population and that collective treatment of these parafunctions is possible.

[Stereognathograph--optoelectronic device for mandible movement recording]. / Stereognathograph--optoelektroniczny przyrzad do rejestracji ruchów zuchwy.

The authors have presented the structure and potentiality of application of a new optoelectronic device called stereognathograph recording the function of mandibular condyles. The meter circuit of this device is placed on the sick's head and connected with the mandible's teeth by means of a peridental splint. It enables to record mandible's movements and in the view onto the horizontal and pterygoid plane and determine the mandibular condyles' position in relation to the chosen reference point in terms of measurable numerical three-dimensional quantities. Furthermore this device enables to designate the axis of rotation of mandibular condyles as well as to designate Bennet's angle and pterygoid angle precisely for individual setting of the SAM-2 articulator.

[Antelocation of mandibular disc. 2. Clinical examination of patients with reverse clicks]. / Doprzednie przemieszczenie krazka stawowego stawu skoniowo-zuchwowego.

119 sick who revealed clicks in mandibular joint during shifting downwords and adduction of mandible i.e. so called reverse dicks. It was possible to eliminate the clicks in the mandibular joint in a new therapeutic positioning of the mandible in 52 patients among these sick. These sick have been examined in details and treated. Algetic syndrome of dysfunction symptoms has also been found in 31 sick (60%) beside reverse clicks in the mandibular joint. The roentgenograms of mandibular joint have demonstrated various kinds of disturbances in the positioning of mandibular condyles in the greatest nodulation of the teeth in 50 sick (96.2%). The initial treatment by means of occlusion splints and/or temporary partial dentures in a new three-dimensional position of the mandible eliminating clicks in mandibular joint has been performed in all 52 sick. Follow-up examinations performed in 38 sick after 3-9 months of using the splints or temporary prosthetic restoration have demonstrated that complete elimination of the clicks in the mandibular joint has been gained in 29 persons under examination (75.3%) and in case of the remaining 9 sick (33.7%) these clicks have only significantly been diminished. From the examinations performed it follows that performing of initial prosthetic treatment is necessary in the sick with reverse clicks.
