Abstract

Excessive and prolonged distress (chronic) can cause damage to periodontal tissues, specifically alveolar bone resorption. Alveolar bone resorption is caused by osteoclast cells activity. The purpose of the research is to determine effect of chronic distress duration to osteoclast cells activity in alveolar bone of male Sprague-Dawley rats attain the age of 3-4 months. The rats were given an electric shock stressor (Electrical Foot Shock) as distress chronic for 7, 14, and 28 days. Stressors were given for 30 minutes at 9 a.m every day during the treatment period. The amount of electrical current is 2-8 mA, 48 V voltages and 0.5 Hz frequency. Osteoclasts activity were observed histologically with 400x magnification using osteoclast Bone Interface (OBI) Index by dividing the length of howship's lacunae with osteoclasts. Result showed signifficant difference at 0.00 (p<0.05) beetwen the variable.Activity of osteoclasts in alveolar bone of Sprague-Dawley rats which were exposed to the stressor is increased when compared to the group that were not exposed to electrical shock stressor, but at day 14 decreased when compared to the other treatment groups. Keyword : chronic distress, osteoclast activity, alveolar bone

Abstract

Chronic distress is a psycho-physiological reaction of stimuli that disrupt homoestasis which cause damage to the body, one of kind is an electrical shock stressor. The distress can increase catecholamines level in considerable amounts and allegedy it produce pro-inflamatory cytokines. Cytokine will affect the Hypoyhalamic pituitary adrenal (HPA) axis to produce cortisol and also act as negative control of cytokines. In this assumption, cytokines can increase bond of osteoclast formation key mediator which is RANKL with its receptor (RANK) to produce osteoclasts. This study was an experimental laboratories research using 8 weeks old Sprague dawley rats with body weight 200-250 gram as samples to observe increase of the number of osteoclasts in the alveolar bone. A total of 32 samples were divided into 4 groups: the rats group exposed with electrical shock stressor  for 0, 7, 14, and 28 days. Then samples were processed by tissue processing  until it’s ready to observe using an electron microscope with 400x magnification. The results showed  that there were significant differences (p <0.05) between groups. It is concluded that the number of osteoclasts alveolar bone osteoclast were increased in Sprague dawley rats that experienced chronic distress. Keywords: stress/distress, cathecolamines, cytokine, cortisol,osteoclast

Abstract

Background: The compressive strength of orthodontic tooth movement will be distributed throughout the periodontal ligament and alveolar bone, resulting in bone resorption on the pressure side and new bone formation on the tension side. Caffeine, a member of the methyl xanthine family, represents a widely-consumed psychoactive substance that can stimulate osteoclastogenesis through an increase in RANKL. A 3D Micro-Computed Tomography (µ-CT) x-ray device can be used to measure orthodontic tooth movement and changes in periodontal ligament width. Purpose: The purpose of this research was to analyze the effects of caffeine on the distal movement distance of two mandibular incisors using 3D µ-CT. Methods: The research subjects (guinea pigs) were randomly divided into four groups. Of the two control groups created, one received two weeks of treatment and the other three weeks. The members of these two control groups were subjected to orthodontic movement but received no caffeine. Meanwhile, the other two groups were treatment groups whose members also received either two or three weeks of treatment. In these two treatment groups, the subjects were subjected to orthodontic movement and received a 6 mg/500 BM dose of caffeine. The orthodontic movement of the subjects was induced by installing a band matrix and orthodontic bracket on each mandibular incisor to move distally by means of an open coil spring. Observations were then conducted on days 15 and 22 with µ-CT x-rays to measure the distal movement distance of the two mandibular incisors and the width of the periodontal ligament. Results: The administration of caffeine increased the tooth movement on day 15 (p<0.05) and day 22 (p<0.05). The increase in the tooth movement on day 22 was greater than that on day 15 (p<0.05). The width of the periodontal ligament on the pressure side of the treatment groups experienced greater narrowing than that of the control groups (p<0.05). Meanwhile, the width of periodontal ligament on the tension side of the treatment groups widened more than that of the control groups (p<0.05). Conclusion: µ-CT x-ray can be used to evaluate the extent of orthodontic movement in addition to the width of the mandibular incisor periodontal ligament during orthodontic tooth movement. Moreover, it has been established that the administering of caffeine can improve orthodontic tooth movement.

Abstract

Microbicidal mechanism with producing free radical superoxide is one of neutrophil response to the bacterialinvasion. When overproducted, the free radical superoxide greater than antioxidan defense system and destroyed thecell itself. P.gingivalis had been knowed as the major bacteria that induce periodontal inflammation. These bacteriacan stimulated neutrophil activities. This was aimed to determinate the superoxide production from neutrophilstimulated with P.gingivalis. Neutrophil as samples were isolated from subject who fulfill the selected criteria. Theintracelluler superoxide production was determinated by nitroblue tetra zolium (NBT)test and the extracellulerproduction by spectrophotometer with wave length 580 nm. The result showed there was superoxide production fromneutrophil stimulated by P.gingivalis. It was concluded that the stimulation of P.gingivalis on neutrophil can promotesuperoxide production both intracelluler and extracelluler.
