Abstract
Background and Aims: Periodontitis does not affect on all patients by the same way. There are some risk factors in some people that make them more sensitive to progress of periodontitis. Smoking, uncontrolled diabetes, and special pathogens increase the risk of periodontitis. Other factors such as stress, depression and anxiety, are not crucial risk factors for periodontitis yet. Biologic explanation of this relation is that mental conditions and exposure to stressful situations can alter immune response. The aim of this study was to review the psychological factors of anxiety and depression associated with periodontitis.
Materials and Methods: For this review article, we have searched through internet by the following keywords periodontal disease, anxiety, depression. We have tried to cover almost all dental– related sites and journals as well as Pubmed from 1990-2010.
Conclusion: Most published studies support a positive relationship between periodontitis and several psycho-social factors. Life style, stressful conditions, hormonal changes, nonchalance in oral hygiene, habits such as smoking are predisposing factors in periodontal diseases.

Abstract
Background and Aims: Pulp necrosis in immature teeth disrupts root development and makes the teeth susceptible to fracture. Regenerative endodontics is a relatively new modality of treatment where the necrotic pulp is replaced with newly formed healthy tissue which has normal functionality. Many clinical reports have demonstrated the potential of this strategy to induce root maturation and apical closure. However, clinical outcomes are patient-dependent and unpredictable. Developing predictable protocols can be achieved through the interplay of three basic elements of tissue engineering, namely, scaffolds, stem cells, and signaling molecules. Furthermore, the clinical success of this treatment is influenced by both the method of preparing the inner space of the root and the type of biomaterial utilized in the coronal part. In this review, we discuss recent advances in tissue engineering-based strategies for regeneration of the pulp/dentine complex along with their advantages and limitations.

Abstract
Background and Aims: Guided endodontics is a new technique that is now evolving. It is used in many treatments, especially in access cavity preparation and locating root canals in teeth with pulp canal obliteration (PCO), microsurgical endodontics, and fiber post removal in retreatments. In addition, this technique is independent of operator experience, requires less treatment time for the patient, and is more precise and safer than conventional endodontics. This technique involves the use of cone beam computed tomography imaging (CBCT), tooth surface scanning, and special software to provide guidance for performing endodontic treatment in a fast, safe, and minimally invasive manner. This review article aims to introduce guided endodontics and to describe its technique, advantages, and limitations.

Abstract
Background and Aims: Oral bacteria play an important role in oral diseases, due to their high adaptability to different environmental areas of the mouth. In this article, an attempt was made to describe the molecular mechanisms involved in the physiological relationships of oral and dental environment bacteria and their pathogenic significance with molecular approaches.
Materials and Methods: The present systematic review was written based on the advanced and standard search of keywords including Oral bacteria, Biofilm, and Dental diseases in PubMed, Springer, Scopus, Medline, Google Scholar, Science Direct, and Web of Science databases. For this purpose, an advanced and systematic search of articles published from 1993 to 2023 was conducted to compile the present article.
Results: Bacteria in the oral cavity have nutritional adaptations that are important for living in pathogen-host relationships, including adapting to proteolytic living conditions, using the host's glycome as a nutritional interface. This includes the use of host-derived sialic acid and other glycosidases in oral bacteria. Some of these bacteria adhere to surfaces such as salivary, epithelial proteins, and glycans, which ultimately lead to biofilm formation. Bacteria living in the oral environment are constantly exposed to a wide range of stress-causing factors and oxidative stress in the biofilm.
Conclusion: Dental caries, pulp, periapical, and periodontitis diseases (including gingivitis) are among the most common bacterial diseases. Among them, tooth decay caused by the presence of Streptococcus mutans is the most common dental disease due to the production of acids from carbohydrate fermentation which is characterized by the demineralization of tooth structure.

Abstract
Background and Aims: Temporomandibular disorders refer to a set of musculoskeletal problems that affect the temporomandibular joint, masticatory muscles, and surrounding anatomical structures. These disorders are associated with symptoms such as pain, click, asymmetry, or reduced maximum opening. The etiology of many temporomandibular disorders is complex, for this reason the initial treatments must be reversible and non-invasive. The use of occlusal splints is effective in reducing symptoms, and therefore, it is recommended in early and even long-term treatment of these disorders. These appliances play major role in developing conditions such as stabilizing joint position, creating favorable occlusal conditions that lead to normal muscle function, and protecting teeth and supporting structures against dental wear. The purpose of this article was to present a comprehensive review of occlusal splints in Persian language.
Materials and Methods: A search on Pubmed and Google scholar databases was done and the keywords "occlusal splints" and "temporomandibular disorders" were used. The inclusion criterion was articles published in English in the field of the types of occlusal splint between 1980 and 2020.
Conclusion: In this review, the occlusal splints and their applications have been introduced.The success or failure of treatment with occlusal splints depends on various factors such as the correct selection of patients, the process of manufacturing, occlusal adjustment of splints, and the patients’ cooperation. |

Abstract
Guided bone and tissue regeneration is a common technique used in the treatment of areas around teeth and dental implants. In this framework, barrier membranes are employed to create a suitable environment that promotes new bone growth while preventing the invasion of foreign cellular components into this specific setting. Attributes such as biocompatibility with living tissues, structural integrity, longevity, and user-friendliness constitute the principal criteria for selecting appropriate membranes for this particular application. Given the extensive diversity of membrane types concerning their sources, texture, architecture, and inherent properties, determining the most suitable variant depends on the clinical condition presented by the patient and the specific treatment modality, thereby emphasizing its considerable importance. In recent years, fibrous membranes have garnered particular attention due to their distinctive characteristics. These membranes, made of natural or synthetic fibers, typically exhibit high porosity, which facilitates the ingress of vascular structures and osteogenic cells. Owing to their porosity and flexibility, fibrous membranes are considered exceptionally suitable for the regeneration of maxillofacial and dental tissues, thereby contributing to increase bone volume, guide its growth, and at the same time prevent soft tissue encroachment into the restoration area, which ultimately has a favorable effect on treatment outcomes. On the other hand, due to the complexity and extent of oral infections, new nanotechnological approaches have been proposed in recent years to reconstruct infected sites in dentistry. These strategies, by targeting specific sites and having non-toxic properties, can help deliver antimicrobial molecules, regenerate tissue, and maintain oral health. In this context, nanofibrous membranes serve as multifunctional structures, both in the controlled release of antimicrobial agents and as scaffolds for the formation of nascent tissue. Overall, fibrous membranes, by mimicking the physiological conditions of the organism, create an ideal environment for the growth and healing of bone tissues, leading to improved effectiveness in dental procedures. This article is devoted in detail to a comprehensive review of polymeric and composite fibrous membranes with drug release potential.
