Immunological aspects of acrylic carnial implants

The purpose of this study was to evaluate the effect of different acrylic cranial implants on serum immunoglobulins level. Fifteen patients were selected for this study. The results obtained showed insignificant change in serum immunoglobulins IgA, IgG, IgM and IgE level in patients receiving heat-processed acrylic resin cranial implants. Significant change in serum immunoglobulins [IgA, IgG, IgM and IgE] level was noticed in patients receiving autopolymerizing acrylic resin and visible light-curing resin cranial implants

Study of clinical and electromyographic changes associated with restoring the vertical dimension in old complete denture wearers

This study was done to evaluate two techniques for restoring the occlusal vertical dimension in 12 old complete denture patients with reduced vertical dimension. Evaluation included recordings of clinical manifestations [symptoms and signs] and EMG activities of both masseter and temporalis muscles, one and two months after reestablishing the vertical dimension either suddenly [group I] or incrementally [group II]. From the results obtained, it can be concluded that sudden restoration of correct vertical dimension was untolerable to the patients in the first month, while their adaptive response was after two months. An incremental increase in vertical dimension was more acceptable, although EMG activities of masseter and temporalis muscles decreased after one month. EMG activities of muscles increased after two months following restoration of vertical dimension

Evaluation of pantographic tracings following application of transcutaneous electrical nerve stimulation in patients with Myofacial Pain Dysfunction Syndrome

This study was designed to evaluate the Pantographic Reproducibility Index [PRI] of patients with myofacial pain dysfunction syndrome [MPD] before and after application of transcutaneous electrical nerve stimulation [TENS] in comparison with control group. It was conducted on 12 dentulous subjects. Six patients were suffering from MPD syndrome [studied group], while the other six subjects were the control group. For each subject, mandibular movements were recorded graphically using Denar Pantograph to obtain pantographic tracings, which were quantitated by PRI scores. After application of TENS, another pantographic tracings were recorded for both groups
