Abstract
Periodontitis is a chronic infectious oral disease with a high prevalence rate in the world, and is a major cause of tooth loss. Nowadays, people have realized that the local microenvironment that includes proteins, cytokines, and extracellular matrix has a key influence on the functions of host immune cells and periodontal ligament stem cells during a chronic infectious disease such as periodontitis. The above pathological process of periodontitis will lead to a defect of periodontal tissues. Through the application of biomaterials, biological agents, and stem cells therapy, guided tissue regeneration (GTR) makes it possible to reconstruct healthy periodontal ligament tissue after local inflammation control. To date, substantial advances have been made in periodontal guided tissue regeneration. However, the process of periodontal remodeling experiences complex microenvironment changes, and currently periodontium regeneration still remains to be a challenging feat. In this review, we summarized the main challenges in each stage of periodontal regeneration, and try to put forward appropriate biomaterial treatment mechanisms or potential tissue engineering strategies that provide a theoretical basis for periodontal tissue engineering regeneration research.

MATERIALS 2021; 14:ma14206123. [PMID: 34683712 PMCID: PMC8537464 DOI: 10.3390/ma14206123] [Citation(s) in RCA: 39] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Revised: 09/28/2021] [Accepted: 10/11/2021] [Indexed: 01/21/2023]
Abstract
Alloplasts are synthetic, inorganic, biocompatible bone substitutes that function as defect fillers to repair skeletal defects. The acceptance of these substitutes by host tissues is determined by the pore diameter and the porosity and inter-connectivity. This narrative review appraises recent developments, characterization, and biological performance of different synthetic materials for bone, periodontal, and dental tissue regeneration. They include calcium phosphate cements and their variants β-tricalcium phosphate (β-TCP) ceramics and biphasic calcium phosphates (hydroxyapatite (HA) and β-TCP ceramics), calcium sulfate, bioactive glasses and polymer-based bone substitutes which include variants of polycaprolactone. In summary, the search for synthetic bone substitutes remains elusive with calcium compounds providing the best synthetic substitute. The combination of calcium sulphate and β-TCP provides improved handling of the materials, dispensing with the need for a traditional membrane in guided bone regeneration. Evidence is supportive of improved angiogenesis at the recipient sites. One such product, (EthOss® Regeneration, Silesden, UK) has won numerous awards internationally as a commercial success. Bioglasses and polymers, which have been used as medical devices, are still in the experimental stage for dental application. Polycaprolactone-TCP, one of the products in this category is currently undergoing further randomized clinical trials as a 3D socket preservation filler. These aforementioned products may have vast potential for substituting human/animal-based bone grafts.

[PMID: 34447156 PMCID: PMC8375783 DOI: 10.4103/jpbs.jpbs_533_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2020] [Revised: 10/30/2020] [Accepted: 11/18/2020] [Indexed: 11/04/2022] Open
Abstract
Aim The aim of this study was to assess the perception, knowledge, and attitude of individuals from different regions of Saudi Arabia toward dental implants and bone grafts. Material and Methods An online, self-oriented, and cross-sectional-based questionnaire with 21 items was given to 1622 individuals from different regions of Saudi Arabia. The questionnaire recorded the perception, knowledge, and attitude of participants and their agreement or rejection of dental implants and various kinds of bone grafts. The responses were compared with age, sex, and educational level. Descriptive statistical analysis was performed for the collected data and P < 0.05 was considered statistically significant. Results Most of the males (35.8%) and females (39.8%) reported that the major source of data regarding dental implants is friends and families. Majority of the participants (approximately 75% males and 73% females) support the idea that dental implants last for lifetime, whereas majority of the participants (approximately 49% males and 56% females) displayed their unawareness regarding materials used for dental implants. The overall acceptance rates of participants for autografts, alloplasts, xenografts from the cow, xenografts from the horse, and allografts were 40%, 15.9%, 2.5%, 2.2%, and 1.6%, respectively. Conclusion The expense of dental implants was considered the foremost reason for avoiding the procedure. Most of the participants think that fixed dental prostheses last longer than removable prosthesis. Autograft was the most accepted bone graft, whereas allograft was the least accepted bone graft over the responded participants.

In Vivo Analysis of the Biocompatibility and Bone Healing Capacity of a Novel Bone Grafting Material Combined with Hyaluronic Acid. Int J Mol Sci 2021; 22:ijms22094818. [PMID: 34062885 PMCID: PMC8124336 DOI: 10.3390/ijms22094818] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2021] [Revised: 04/26/2021] [Accepted: 04/28/2021] [Indexed: 12/28/2022] Open
Abstract
The present in vivo study analyses both the inflammatory tissue reactions and the bone healing capacity of a newly developed bone substitute material (BSM) based on xenogeneic bone substitute granules combined with hyaluronate (HY) as a water-binding molecule. The results of the hyaluronate containing bone substitute material (BSM) were compared to a control xenogeneic BSM of the same chemical composition and a sham operation group up to 16 weeks post implantationem. A major focus of the study was to analyze the residual hyaluronate and its effects on the material-dependent healing behavior and the inflammatory tissue responses. The study included 63 male Wistar rats using the calvaria implantation model for 2, 8, and 16 weeks post implantationem. Established and Good Laboratory Practice (GLP)-conforming histological, histopathological, and histomorphometrical analysis methods were conducted. The results showed that the new hyaluronate containing BSM was gradually integrated within newly formed bone up to the end of the study that ended in a condition of complete bone defect healing. Thereby, no differences to the healing capacity of the control BSM were found. However, the bone formation in both groups was continuously significantly higher compared to the sham operation group. Additionally, no differences in the (inflammatory) tissue response that was analyzed via qualitative and (semi-) quantitative methods were found. Interestingly, no differences were found between the numbers of pro- and anti-inflammatory macrophages between the three study groups over the entire course of the study. No signs of the HY as a water-binding part of the BSM were histologically detectable at any of the study time points, altogether the results of the present study show that HY allows for an optimal material-associated bone tissue healing comparable to the control xenogeneic BSM. The added HY seems to be degraded within a very short time period of less than 2 weeks so that the remaining BSM granules allow for a gradual osteoconductive bone regeneration. Additionally, no differences between the inflammatory tissue reactions in both material groups and the sham operation group were found. Thus, the new hyaluronate containing xenogeneic BSM and also the control BSM have been shown to be fully biocompatible without any differences regarding bone regeneration.

Abstract
The aim of this review was to systematically assess bone regeneration by using antiosteoporotic drugs in adjunction with bone grafting compared with controls (bone grafting without the administration of antiosteoporotic drugs). The review also evaluated statistical differences in the effect between systemic and local routes of drugs. Also, the effect of type of drugs (anticatabolic vs. anabolic) was subevaluated. PubMed and EMBASE (via OvidSP) resulted in inclusion of 60 animal studies. The studies were assessed for reporting quality and risk of bias. Outcome data from selected studies were categorized as either experimental (bone grafting with the administration of antiosteoporotic drugs) or control. Meta-analysis of selected studies was done for these outcomes: histomorphometrical bone area (BA%) and micro-CT bone volume (BV%). In this review, several animal models (52 healthy, 6 osteoporotic, and 2 both conditions) were subjected to examine the effect of antiosteoporotic drugs on bone grafting, with a predominant use of rodent species. Assessment indicates poor reporting quality and unclear risk of bias in the majority of studies. Random-effects meta-analysis revealed a significant increase in overall BA% (mean difference [MD]: 2.6, confidence interval [CI]: 2.25 to 2.92) and BV% (MD: 0.12, CI: 0.05 to 0.19) due to osteoporotic drug treatment compared with controls. For subgroups, both routes of antiosteoporotic drug administration showed similar effects on BA%. In contrast, systemic antiosteoporotic drug administration led to significantly higher BV% (MD: 6.75, CI: 5.30 to 8.19) compared with local administration (MD: 0.02, CI: -0.03 to 0.08). Further, administration of anabolic drugs significantly increased BA% (MD: 5.75, CI: 4.62 to 6.87) compared with anticatabolic drugs (MD: 1.86, CI: 1.47 to 2.26). In conclusion, both histomorphometrical and micro-CT scan analysis indicated an overall effect of using the antiosteoporotic drugs toward bone regeneration in adjunction with grafting. However, not all studies showed a positive effect and the present results need to be applied with care, as the included papers showed experimental heterogeneity for animal models. Further (pre)clinical research is warranted to explore whether drug-based strategies can be an effective adjunctive with bone grafting. Impact Statement The aim of this meta-analysis was to assess whether antiosteoporotic drugs can promote bone regeneration in adjunction with bone grafting by using preclinical animal models. Although the majority of included studies indicated poor reporting quality and unclear risk of bias, an overall positive effect of the antiosteoporotic drugs toward bone regeneration related to bone grafts can be highlighted.

Abstract
Because of its high biocompatibility, bio-degradability, low-cost and easy availability, cellulose finds application in disparate areas of research. Here we focus our attention on the most recent and attractive potential applications of cellulose in the biomedical field. We first describe the chemical/structural composition of cellulose fibers, the cellulose sources/features and cellulose chemical modifications employed to improve its properties. We then move to the description of cellulose potential applications in biomedicine. In this field, cellulose is most considered in recent research in the form of nano-sized particle, i.e., nanofiber cellulose (NFC) or cellulose nanocrystal (CNC). NFC is obtained from cellulose via chemical and mechanical methods. CNC can be obtained from macroscopic or microscopic forms of cellulose following strong acid hydrolysis. NFC and CNC are used for several reasons including the mechanical properties, the extended surface area and the low toxicity. Here we present some potential applications of nano-sized cellulose in the fields of wound healing, bone-cartilage regeneration, dental application and different human diseases including cancer. To witness the close proximity of nano-sized cellulose to the practical biomedical use, examples of recent clinical trials are also reported. Altogether, the described examples strongly support the enormous application potential of nano-sized cellulose in the biomedical field.

Abstract
The study was designed to evaluate the clinical outcome of a composite material, beta-tricalcium phosphate in combination with calcium sulphate, in the treatment of periodontal intrabony defects. The combination of these materials is believed to aid in guided tissue regeneration owing to their properties. A total of 47 teeth with intrabony defects in 26 periodontitis patients were treated with Fortoss® Vital (Biocomposites, Staffordshire, UK). Clinical parameters were evaluated which included changes in probing depth, clinical attachment level/loss and gingival recession at the baseline and 2 years postoperatively. The mean differences in measurements between the baseline and 2 years postoperatively were a reduction of 2.07±1.14 mm (p=0.000) in case of probing depth and a gain of 1.93±1.36 mm (p=0.000) in clinical attachment level; but an increase of 0.14±0.73 mm (p=0.571) in gingival recession. The study results show that the treatment with a combination of beta tricalcium phosphate and calcium sulphate led to a significantly favorable clinical improvement in periodontal intrabony defects 2 years after the surgery.

Abstract
Acetabular defects are a particular challenge during THR revision. Defects may be filled with autologous bone grafts, allografts or synthetic bone substitute materials. In this preliminary, retrospective study, 22 patients were treated with an oval shaped revision cup and a combination of synthetic bone substitute materials, namely hydroxyapatite and beta-tricalcium phosphate. The postoperative outcome was evaluated regarding the functional clinical outcome and quality of life using the Harris hip score, the WOMAC and the SF-36. Signs of loosening and changes of the implant position were evaluated from plain radiographs. Follow up examinations were performed after an average duration of 20.5 months (7-33 months). Postoperatively, we found a significant increase of the Harris hip score, and an increase in both the SF-36 and the WOMAC scores (without statistical significance). No radiographic signs of loosening were evident at the time of follow up. The use of synthetic bone substitute materials offers a possible alternative to the use of autologous and allogenic bone grafts in acetabular revision surgery. Further randomised controlled long-term studies are needed to verify the promising short-term results and to determine potential side effects, such as possible third body wear.

Abstract
The present preclinical and clinical study assessed the inflammatory response to a high-temperature-treated xenogeneic material (Bego-Oss) and the effects of this material on the occurrence of multinucleated giant cells, implantation bed vascularization, and regenerative potential. After evaluation of the material characteristics via scanning electron microscopy, subcutaneous implantation in CD-1 mice was used to assess the inflammatory response to the material for up to 60 days. The clinical aspects of this study involved the use of human bone specimens 6 months after sinus augmentation. Established histologic and histomorphometric analysis methods were applied. After implantation, the material was well integrated into both species without any adverse reactions. Material-induced multinucleated giant cells were observed in both species and were associated with enhanced vascularization. These results revealed the high heat treatment led to an increase in the inflammatory tissue response to the biomaterial, and a combined increase in multinucleated giant cell formation. Further clarification of the differentiation of the multinucleated giant cells toward so-called osteoclast-like cells or foreign-body giant cells is needed to relate these cells to the physicochemical composition of the material.

Abstract
High mobility group box 1 (HMGB1) was originally defined as a nuclear protein. However, later studies showed that HMGB1 was released from damaged cells into the extracellular milieu and functioned as a danger signaling molecule. HMGB1 has also been shown to exert proliferative and chemoattractant effects on many cell types. In this study, we investigated the in vitro effect of human recombinant HMGB1 on the proliferation and migration of human gingival fibroblasts (HGF) and human periodontal ligament fibroblasts (HPDLF). For the proliferation assay, HGF and HPDLF were cultured in the presence of 5, 10, and 50 ng/mL HMGB1. After a period of 6 days, cell proliferation was determined by MTT assay. The migration assay was performed by culturing the two cell types in Transwells with HMGB1 in the lower chamber as a chemoattractant. Cell migration during 16 h was determined by crystal violet staining of the cells that migrated across the membrane. The results showed that HMGB1, at 50 ng/mL, was able to significantly induce proliferation of HGF by up to 171.4 ± 17.1%. No such proliferation induction was seen for HPDLF. In the migration assay, however, 100 ng/mL HMGB1 induced migration of both cell types. The counts of cells that migrated across the membrane, as compared with the control, were increased to 273 ± 24.1% and 410.3 ± 158% for HGF and HPDLF, respectively. Since proliferation and migration are basic abilities of cells required for proper tissue repair, these data suggest that HMGB1 plays an important role in these functions of periodontal cells.

Abstract
Mesenchymal stem cells deriving from dental pulp differentiate into osteoblasts capable of producing bone. In previous studies, we extensively demonstrated that, when seeded on collagen I scaffolds, these cells can be conveniently used for the repair of human mandible defects. Here, we assess the stability and quality of the regenerated bone and vessel network 3 years after the grafting intervention, with conventional procedures and in-line holotomography, an advanced phase-imaging method using synchrotron radiation that offers improved sensitivity toward low-absorbing structures. We found that the regenerated tissue from the graft sites was composed of a fully compact bone with a higher matrix density than control human alveolar spongy bone from the same patient. Thus, the regenerated bone, being entirely compact, is completely different from normal alveolar bone. Although the bone regenerated at the graft sites is not of the proper type found in the mandible, it does seem to have a positive clinical impact. In fact, it creates steadier mandibles, may well increase implant stability, and, additionally, may improve resistance to mechanical, physical, chemical, and pharmacological agents.

Abstract
The pilot study deals with the clinical results of the regenerative therapeutical method in intraosseous periodontal defects done by surgical augmentation procedure using a material of a new generation prepared on the basis of a bioactive glass. A group of 10 individuals were treated properly for chronic periodontitis. Some of treated infraalveolar periodontal lesions, both periodontal pockets and interradicular defects, persisted or recurred in posterior teeth. In order to eliminate them they were indicated for advanced periodontal surgery or regenerative surgical therapy stimulating healing processes of supportive tissues, mostly alveolar bone around treated teeth. Relevant clinical parameters, i. e. values of the pocket depth, gingival recession, and loss of attachment were evaluated before and after the periodontal surgery and compared with each other. The therapy led to significant improvement of clinical parameters in terms of the reduction of pocket depth and loss of attachment values.
