Cytochemical criterions of periphery blood activity in case of prosthetic patients’ somatic pathology

 

Despite on the dental implantology successes there are still some questions connected with prophylactics of inflammatory complications in periimplantic tissues. For successful result of treatment and prolongation of fixed implant-supported prostheses’ useful lifetime, well-timed control under the condition of round-implant tissues in the patients with gastric and duodenal ulcer disease is necessary because according to results of multiple researches changes in GIT are the start point of many dental diseases. Among the lesions of inner organs the lesions of GIT causes the biggest changes in mouth cavity. The clinical success of patients’ prosthetic treatment using dental implants is possible only upon condition of round tissue structures’ effective rehabilitation and depends particularly from morphofunctional condition and reactivity of supporting soft tissues. On the assumption of above mentioned the target of our investigation is the carrying out of neutrophils cytochemical analyzes in peripheral blood in the prosthetic patients after interosseal implants installation against gastric and duodenal ulcer disease.

The material of our investigation is the peripheral blood of patients after dental implantation. For the carrying out of investigation 87 patients (37 women and 50 men) in the age from 21 to 64 years were examined. Selecting the patients we keep in mind their general state, past and          concomitant diseases, anatomico-physiological state of mouth cavity. Patients were divided on 3 groups: first group consisted of 20 prosthetic patients without somatic pathology, second group consisted of 27 prosthetic patients with somatic pathology (gastric and duodenal ulcer disease) and the third group from the 25 patients with background disease requiring prosthetic help, which were every other day injected with 1 ml single-dose of the “Erbisolum”. Also15 persons without any dental pathology were examined as the control group (norm).  During carrying out of the investigation we’ve used “Erbisolum” medicine – the immunomodulator, restorer and adaptogen.  Peripheral blood sampling for investigation was made on the first, third, sixth and twelfth month after implants’ installing.  

The studying of lactic dehydrogenase (LDH) and succinate dehydrogenase (SDH) activity represents big interest, because their level and activity is considered to be heterospecific criteria of cell damage. For the calculation of blood enzymes activity we’ve used Astaldi method based on medium cytochemical level (MCL) calculation by formula:

MCL =

where:

x – number of cells in one smear with certain level of enzymatic activity from 100 of viewed neutrophils;

1,2,3,4 – level of activity;

100 – number of viewed neutrophils in one smear.

Thereby there were distinguished 4 levels of activity (fourth stage – neutrophil is fully covered by formazan granules,  third stage – ¾ of activity, second stage – ½ of activity and first stage – ¼ of activity).

Cytochemical exponents analyze in periphery blood neutrophils in prosthetic patients after an implant installation showed that in all the three groups statically significant decreasing of aerobic oxidation in relation to control group (p<0,05) and growth of anaerobic glycolysis was marked after the first month of investigation. To the third month of investigation significant decreasing of aerobic oxidation in periphery blood neutrophils was marked in all groups but it was the most expressed in second group where MCL of SDH was 1,34±0,05 c.u which was on 27,5% lower than in control group (p<0,01), thereat LDH activity (anaerobic glycolysis) showed reverse conformity, it was increased on 25,9% (p<0,01) and it was 2,87±0,15 c.u. To the sixth month of investigations in first group (prosthetic patients without somatic pathology) and in the third group (prosthetic patients with somatic pathology and “Erbisolum” immunomodifier usage) was observed the normalization of neutrophils’ cytochemical activity, where they’ve got statically insignificant character in relation to control group (p>0,05). However by this time cytochemical imbalance in second patients’ group was on the high level and was statically significant and approaching of cytochemical exponents to control level in this group was marked only after six month of investigations.

Carried out investigations of periphery blood neutrophils cytochemical activity in prosthetic patients after dental implantation showed that implant installation by itself is accompanied by decreasing of aerobic oxidation and growth of anaerobic glycolysis. Somatic pathology presence leads to more significant cytochemical imbalance.

Conclusions:

1. Implants installation is an energy-consuming and traumatic process by itself what is shown by statically significant decreasing of aerobic oxidation (SDH) and growth of anaerobic glycolysis (LDH).

2. Presence of background disease in prosthetic patients (gastric and duodenal ulcer disease) is manifested by more overt changing of periphery blood neutrophils cytochemical activity and significantly slows down reparation processes.

3. “Erbisolum” immunomodifier usage increases reparation processes and accelerates adaptation processes after implants’ installation.
