Systemic Supplement with Resveratrol Increased Bone Formation in Rats' Alveolar Socket/Aumento de la Formacion Osea en el Hueso Alveolar de Rata con Suplemento Sistemico con Resveratrol.

INTRODUCTION

The aesthetic and functional reconstruction of hereditary degenerative disorders, cleft palate, bone defects resulted from pathological or traumatic incidents, and sport related injuries have been subject of many clinical and laboratory studies. In past 30 years, vast information on bone reconstruction mechanism has been provided (Singh et al, 2000; Liu et al, 2005).

Different techniques and materials were used as regenerative materials for bone reconstruction. Biologic material like autologous, homologous or heterologous transplants, combination substitute materials and alloplastic material such as Hydroxyapatite or Polyethylen have been under examination through several studies (Pang et al, 2004; Zhou et al, 2009). Although there is current research on finding appropriate substitute material for destructed bone, but it seems the best method for reconstruction in bone defect continues to be, to induce bone to reconstruct itself. Consequently, several drugs have been used to accelerate and amplify ossification in bone regeneration (Casarin et al, 2014).

Resveratrol is a phytoalexin found in grapes, peanut and mulberries with various beneficial biological and pharmacological properties (Casati et al, 2013). It is reported that resveratrol can accelerate metabolic pathways and it has been shown that resveratrol has direct increasing effects on osteogenesis (Casarin et al.).

Resveratrol has been shown to increase osteoblastic differentiation gene expression. Also it has the ability to elevate alkaline phosphatase and Prolylhydroxylase levels dose dependency (Khazaei et al., 2012). Resveratrol can increase osteoblast differentiation and osteogenic cells from mesanchymal stem cells (Khazaei et al, 2014). In essence, resveratrol has anti-inflammatory properties and has the ability to inhibit inflammatory molecules. It this drug also has inhibitory effects on intrinsic inflammatory mediators such as tumor necrosis factor (TNF), IL-1, IL-6, IL-12 and interferons (Khazaei et al., 2014). It also elevates protein production by osteogenic cells. Reports indicated that resveratrol has accelerating effect on division of mesenchymal stem cells and differentiation of osteoblast and has positive outcomes overall in osteogenesis.

Evidence suggests that resveratrol may be beneficial and can be considered as supplemental treatment in socket and ridge preservation. Hence, the aim of the present study was to investigate the effect of systemic supplement of resveratrol for post-extraction alveolar socket preservations.

MATERIAL AND METHOD

In this study 30 Wistar rats (Pasteur Institute, Tehran, Iran) were selected using convenient sampling method. Samples were chosen due to inclusion criteria with improbable approach. The samples were 5 weeks old on average, and weighed 110 to 120 g. Samples were treated with standard protocols, free access to water and food; they had access to the same number of light and dark hours. Rats were delivered to the laboratory few days before the study began. They were kept in cages with air filter. Temperatures of the cages were 70 [+ or -] 5 [grados]F and 20 % humidity. A light and dark cycle of hours were arranged every 12 hours for the rats. The rats were divided to 2 groups randomly. Matching technique was used to divide study and control group with equal demographic distributions. The study was conducted with Oral and Maxillofacial surgeons for the surgical procedures. An oral and maxillofacial pathologist looked into pathologic samples and an epidemiologist was assigned to analyze the data gathered from results. All of the investigators were blinded of the groups.

In order to extract second molar teeth ketamine hydrochloride 10 % (80 mg/kg) and xylazine (8 mg/kg) were used for general anesthesia. During anesthesia, samples were monitored with their vital signs, breathing count and heartbeat. For extracting the teeth, custom made hemostat forceps were used. For bleeding control sterile gauze and cotton rolls were used.

For the next 28 days, mice were kept in the same condition as two groups, study group and control group. During these 28 days, one group was used as study group and the other as control group. The study group rats received ab dominal injection of 20 mg/kg resveratrol (Sigma-Aldrich[R], Germany) every day. Placebo injections were conducted in control group rats. Rats had standard diet during the experiment time of 28 days (Ali-Erdem et al., 2011). After 28 days of treatment, subjects were sacrificed and histological samples were collected from center second molar sockets.

Bone samples were decalcified in EDTA 10 %. Then 5 micron cuts were made through the samples and after preparation they were observed under light microscope. Digital images with 400 x magnification were observed and evaluated for new bone formation, inflammation, necrosis, fibrosis, and foreign body reaction. Inflammation and fibrosis were graded as + (1-30 %), ++ (30-60 %) and +++ (60-100 %). Necrosis and foreign body reaction was graded with "YES" (as presence of necrosis and foreign body reaction) and "NO" (as no presence of necrosis and foreign body reaction). New bone formation was registered with percentile of presence of new bone; the newly formed trabecules were observed in several perspectives. The formation of trabecules was measured in a 30x40 grid surface with counting the grids with new bone formation (Shahriari et al., 2012).

Data were analyzed by SPSS 16 using Mann-Whitney U and Fisher Exact test. P-value less than 0.05 considered as significant level.

RESULTS

The mean bone formation in control group was 28.30 % and in study group treated with resveratrol was 45 %. There were significant statistical differences between control group and study group results due to new bone formation (Mann-Whitney U, P-value=0.037) (Table I and Fig. 1).

Inflammation was higher in control group in comparison with study group. Although the amount and the intensity of inflammation was not significantly different in control and study groups (Fisher Exact test, P-value=0.99). There was no evidence of dense and focal inflammatory response in neither of groups (Fig. 1). There was no significant difference between the groups in the term of fibrosis (Fisher Exact test, P-value=0.99) (Fig. 1). There were no detected necrotic foci in the group treated with resveratrol. However, in control group, 3 out of15 samples showed sites of necrosis. Although statistical analysis showed no significant difference between study groups and sample groups (Fisher Exact test, P-value=0.224). Foreign body reaction was not detected in any of the control group samples and there were no significant difference between study groups and control groups (Fisher Exact test, P-value=0.224).

DISCUSSION

Results of the present study showed that resveratrol can be considered as supplement treatment for alveolar socket preservation.

Bone healing after surgical procedures is a process of regaining structure and function. The process of healing is based on osteoblasts' activity and osteogenic cell's differentiation and their migration patterns (Andrade et al, 2013). Studies suggested that 4 weeks is an appropriate time for cells initiate and progress in bone formation (Gerstenfeld et al., 2005; Ejiri et al., 2006). It is shown that aryl hydrocarbons can be strong inhibitors for osteoblast differentiation and can induce osteoclast activity. Resveratrol is a potent inhibitor of aryl hydrocarbon receptor and can stop the effects of its activation (Singh et al.). Moreover, resveratrol has antioxidant, anti-inflammatory, anti-aging effects that makes this herbal substance a positive effect on bone healing process (Cottart et al., 2010; Sanchez-Fidalgo et al., 2010).

The present study have shown that systemic application of resveratrol showed improvement of bone healing process with limited side effects. Some studies have reported that resveratrol can up-regulate translation of Bone Morphogenic Protein-2 (BMP-2), Bone Morphogenic Protein-7 (BMP-7) and OPN (Osteopontin). Up-regulating BMP gene production can have great impact on bone formation process. Although, it is shown that resveratrol could not release BMP-6 in the cell culture medium (Gruber et al., 2003; Su et al., 2007). Casarin et al. has investigated effects of resveratrol application on bone healing process and showed that resveratrol can accelerate production of osteoproteins in mice.

On the other hand, it has been reported that resveratrol up-regulates vitamin D receptors in bone marrow cells which will result in more osteoblastic differentiation and inhibition of osteoclastic activities (Boissy et al., 2005; Song et al., 2006; Kupisiewicz et al., 2010). This phenomenon can accelerate bone healing after surgery, tooth extraction and makes it suitable material for alveolar socket preservation. Dai et al. (2007) reported that resveratrol can accelerate human osteoblastic maturation and mesenchymal stem cell differentiation in human cells. In an in vitro study resveratrol has a dose dependent relationship with osteoblast maturation and differentiation. The presence of resveratrol can elevate osteogenic markers. This report indicated that mesenchymal stem cells and osteoblasts' reproduction was increased in the presence of resveratrol.

Resveratrol reduces secretion of inflammatory cytokines such as IL-8 that has a bone destructive effect. IL-8 is also a strong chemokine (chemo-attractant) for neutrophils to inflammation location. With the presence of more inflammatory cells, the destruction of present structures will be more significant. Studies have reported that IL-8 elevates in inflammatory periodontitis and periodontal treatments reduce its amount.

The present study was preclinical study of our future clinical trial to evaluate the side effect and histopathological effect of resveratrol. The randomization and blinding were done in the current study which is one of the strengths of this pilot study. Although the evidence supports the effectiveness of resveratrol on bone healing, more studies are require to evaluate its side effects, dosage, and time of application. There are limited animal and clinical studies about effects of this drug on healing bone defects. Therefore it seems necessary to conduct more studies and provide more significant data for backing up this hypothesis.

In conclusion, resveratrol can be considered as supplement drug for enhancing bone formation in alveolar socket preservation.
