The masticatory cycle is a complex process and it depends on many factors. In our study we wanted to prove to what extent various types of food consistency influence the masticatory motions, especially the extent of forward, downward and lateral motions of the mandible. Nineteen study subjects aged from 20 to 37 years and with intact teeth rows were asked to chew three types of food of various consistency (banana, bread and carrot). The motions of the mandible were recorded by stereo-photo-grammetric system. Study results have shown that in all 19 study subjects the increase in food consistency increases the extent of masticatory motions. The average size of forward mandibular motion in all 19 study subjects when chewing banana amounts to 2.65 mm, when chewing bread it is 2.96 mm and 3.64 mm when chewing carrot. The average size of downward mandibular motion for all 19 study subjects amounts to 6.79 mm when chewing banana, 7.17 mm when chewing bread and 8.09 mm when chewing carrot. The average size of lateral mandibular motion in all 19 study subjects amounts to 2.46 mm when chewing banana, 2.80 mm when chewing bread and 3.40 mm when chewing carrot. Although varying from subject to subject, the masticatory cycle significantly depends on food consistency. By increasing the consistency of a mouthful, the extent of mandibular motion increases in every single study subject.

Conclusion: Suicidality of breast cancer patients is associated with QOL domains but not with clinical characteristics of the illness. Decreasing of faith is associated with suicidality.

RESUMO ABSTRACTRadioterapia; Neoplasias de cabeça e pescoço; Efeitos de radiação; Cárie dentária.Radiotherapy; Head and neck neoplasms; Radiati on eff ects; Dental caries. Objecti ve: To determine the incidence of radiati on induced caries in conventi onally treated pati ents with head and neck cancer in Bosnian populati on. Method: A number of 30 pati ents with malignant diseases were included into this study, from the Clinic for Maxillofacial Surgery and Clinic for Otorhinolaryngology. All the pati ents were treated with radiotherapy in the region of head and neck, at the Insti tute for Oncology, Clinical Centre of University in Sarajevo. All thirty pati ents were examined in four ti me periods: before the radiati on, 3 weeks aft er commencing the radiati on, three months aft er commencing the radiati on and six months aft er commencing the radiati on.

Background and Aims:Bruxism is the most common form of maxillofacial hyperkinesia. Behavioral disorders as well as affective psychological factors, depression and anxiety being one of the most prominent factors, can together with emotional stress, induce bruxism. There has been the correlation between medications and bruxism (for example SSRI's).Method:We reported a case of a 47-year-old female patient who has been psychiatrically treated for depression since 1988 (F 32.1 by ICD 10). In 2005, she was hospitalised for the second time, this time for depression with psychotic traits (F 33.3 by ICD 10) due to which she was also hospitalised in 2006 and 2007. During 2005 and 2006 she was taking mirtazapine, paroxetine as well as olanzapine and since 2007 she has been taking sertraline and olanzapine.Results:There was an excessive wear of tooth surfaces and edges due to bruxism on seven-year-old bridge, which she noticed herself two years ago. She was awake during the diurnal bruxism and nocturnal bruxist activity was confirmed by her husband. Michigan splint was fabricated, thus alleviating the destructive impact of masticatory forces on the teeth and their supportive tissues.Conclusions:Bruxism, associated with medications or mental disorders and very detrimental to teeth, the periodontium and oral health in psychiatric patients should be also treated as a general health problem and oral health problem. The prognosis for stopping bruxist activity is bad because a complete prosthodontic treatment was extremely limited due to the patient's psychiatric condition.
