Speed change of salivation and biopotentials of oral cavity in orthopedic patients with bridges based on implants

Salivation, (Latin salivatio) - allocation of the salivary glandsthe saliva, large salivation reflex occurs when food stimulate the sensory nerve endings of the oral cavity or under the influence of conditioned stimuli (sight, smell of food). Minor salivary glands secrete continuously moisturizing the mucosa.

Salivation is controlled by the autonomic nervous system. Salivation centers located in the medulla oblongata. Stimulation of the parasympathetic endings causes a large amount of saliva with low protein content. Conversely, sympathetic stimulation leads to secretion of a small amount of viscous saliva. Secretion of saliva without stimulation occurs at a rate of about 0.5 ml / min.

Branch of saliva decreases during stress, fright, or dehydration and almost stops during sleep and anesthesia. Strengthening saliva occurs under the action of the olfactory and taste stimuli, as well as due to mechanical irritation and large food particles during chewing.Average per night stands 1-2.5 liters of saliva.

Biopotential ( action potential , obsolete bioelectrical ) - energy characteristic of the interaction of charges being investigated in living tissue.The potential difference between the excited and unexcited parts of individual cells is always characterized by the fact that the potentialthe excited part of the cell is less than the capacity of the unexcited . Fabric potential difference is determined by a set of potentials of individual cells.Aim of this study was to investigate the rate of salivation in patients with bridges after prosthesis implant , as well as changes biopotentials of the mouth in orthopedic patients with bridges based on implants.

Methods of investigation

26 people were surveyed, both sexes require orthopedic treatment with bridges .Determining the speed of salivation to assess the functional state of the tissue maxillofacial elected speed indicators salivation as salivary glands - perfect test object to identify general pathology . Saliva collection was performed in the morning after a 2-3 hour postprandial using volumetric centrifuge tubes , through spitting during 5 min. ( Unstimulated saliva) . After centrifugation, the amount of saliva was measured . Salivation rate expressed in ml / min.

To study biopotnetsials of the mouth we used biopotnetsials measurer BPM 03.Procedure : Install the Power Supply 8 elements of type 34399 (1.5V ) batteries . Connect the electrodes to the EP instrument jacks on the electrode electrolytic keys from the kit and drop the latest in a glass with saline. Switching on the instrument by the button "On" , 5 min handle "balance" set 00,0-00,1 testimony .Measurements were made at an open mouth , placing the ends of the electrolytic keys to the required land - implantation ,covering design - plastic - mucosa . The result appears on the scoreboard in millivolts.

Research results

In studying the rate of salivation in orthopedic patients wearing bridges implant revealed that: by 1 month after prosthetic salivation rate was 0,71 ± 0,029 ml. / Min., which was 5.9% (P> 0.05) higher than the control, which was 0,67 ± 0,028 ml / min.

By 3 months of follow-rate increase salivation was marginally 2.6% was of the nature of statistically significant (P> 0.05).

In the long-term period of 6-12 months of observations in this group of patients, performance speed control salivation approached and were 0,68 ± 0,029 ml / min.When analyzing potential elektro oral conductivity indicator in the control group (healthy individuals) was 15b, 0 ± 3,7 mV.,.

After prosthesis with bridges to the first month he was slightly increased and 170,0 ± 2,5 mV, which was 8.9% (P> 0.05) higher benchmarks.To 3 months after prosthesis, this figure was higher than the control by 5.2% (P> 0.05) amounting 165,0 ± 4,2 mV.

At 6-12 months of follow-electric potentials during long-term oral orthopedic patients wearing bridges approaching benchmarks and was 158,0 ± 2,8 mV.

Conclusions.

Conduct a detailed study of the velocity and salivation of biopotentials mouth in orthopedic patients, allowed to come to the conclusion that the installation of bridges (made of acrylates) implant has no significant changes in the rate of salivation and biopotentials indicators, as evidenced by indicators of these studies .
