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.

Background and Aims The purpose of this study was to evaluate the survival rate, mean bone loss and post operative complication of implants inserted in All-on-4 technique .

Materials and Methods: The literature was searched using keywords angled implant, All-on-4, tilted implant and graftless technique in the last 10 years (2001 to 2011) and clinical trial article that evaluated survival rate and mean bone loss around axial and tilted implants in All-on-4 technique was selected and evaluated.   A total of 73 articles were found by searching. After evaluation of titles and abstracts, finally 10 clinical trial, that were fully consistent with including criteria such as mean of bone loss and survival rate was selected and evaluated. 

Conclusion: Results showed that the survival rate (96-100%) and mean bone loss (0.34-1.9 mm) with All-on-4 technique in immediate loading is comparable with other implant support treatment plan. Comparison of implant survival and bone loss in axial and tilted implant in All-on-4 system is shown this treatment plan has consistent result with other conventional implant support prosthesis. Also, postoperative complication including fractures of the acrylic temporary prosthesis, detachment of the teeth, abutment or prosthesis screw loosening have been reported with All-on-4 technique.

Background and Aims: Pregnancy is a period with hormonal and psychological changes affecting women’s oral health. The aim of present review study was to evaluate, elaborate and categorize factors affecting oral health status of pregnant women.
Materials and Methods: A literature search with the following keywords: pregnancy, “pregnant women”, “pregnant mothers” and “expectant mothers” , AND dentistry, “dental health” and “oral health” in PubMed and Scopus was performed from 2009 to 2019. Search results included 1435 articles which 467 duplicate studies were excluded. Finally, 30 articles were included in the study. Oral health outcomes were categorized and significant relationships with determinants and risk factors were reported.
Results: Most studies (70%) were performed cross-sectionally. Among the studied outcomes, dental visit, periodontal disease and dental caries were the most common. The most studied independent variables were socioeconomic factors and demographic factors, followed by behavioral and enabling factors. The lowest frequency was related to the systemic factors. Mothers’ education and age were examined more than other variables and in about 40% of studies had significant association with outcomes. Dental counseling was assessed in only 3 studies and in all three studies, the relationship with outcome was significant.
Conclusion: Socioeconomic, demographic and enabling factors could affect the oral health of pregnant women.

Background and Aims: Due to the prevalence of corona virus and restrictions on access to health care in the community, there are clearly many concerns and problems for the lives of people, especially the elderly. Older people are at higher risk for this type of virus than the other ages. The purpose of this study was to investigate the status of dental services for the elderly during the corona outbreak and to provide solutions related to oral health of the elderly during the corona virus pandemic.
Materials and Methods: The present review study was performed and the selected keywords were: coronavirus and dentistry, dentistry and the elderly, corona and the elderly. Articles were selected based on findings and related texts. English language articles were selected using Google Scholar, Science direct, PubMed and Research Gate search engines. Sources were reviewed between January 2019 and October 2020. Based on inclusion and exclusion criteria, 15 articles were reviewed.
Results: Research findings showed that most studies have pointed to the importance of mobile and tele-dentistry. In a coronary pandemic, it is very important to correctly diagnose the patient's problems and determine the best type of treatment for the elderly. In addition, the elderly should be prevented from entering the unnecessary dental treatments.
Conclusion: Many elderly people avoid the treatment of oral diseases during coronavirus pandemic due to fear of coronavirus, high dental costs, lack of access to appropriate services, and this causes irreparable problems in their health. Therefore, it is recommended to provide practical solutions to facilitate the dental treatment of elderly patients.

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.
