Abstract
Nano science and nanotechnology have revolutionized all aspects in the endodontic field. The aim of the present study was to describe the application of nanotechnology in endodontics by reviewing the literature.The application of nanomaterials, with a smaller size, for surface modification has reduced the incidence of failure in the rotary nickel-titanium files. Nanoparticles with the ability of rapid dispersion into the hard-to-reach spaces in the complex root canal system have a better antimicrobial effect. The incorporation of nanoparticles in the obturating materials promotes the sealing properties and antimicrobial efficacy. Nanoscaffolds in the pulp regeneration approaches, bioceramics as retrofilling, and repair materials, and Nanorobots and nanoterminators as new technologies for local anesthesia with fewer side effects are some examples in this regard.

Abstract
Backgrounds and Objectives: Afew large population-based studies have been conducted on the prevalence of oral mucosal lesions in relation to fertility status in the Iranian population. The aim of study was determine the prevalence of oral mucosal lesions in relation to fertility status in women participants of Shahedieh cohort study.
Materials and Methods: A descriptive cross-sectional study was conducted on 4935 women who participated in the Shahedieh cohort study. The age range of participants was 35-71 years with a mean age of 47.12 years. The prevalence of oral mucosal lesions considering fertility variables including pregnancy, number of pregnancy, oophorectomy, tubectomy, hysterectomy, infertility, menopause, normal menopause, and abortion, application of infertility and oral contraceptive drugs and hormone replacement therapy were recorded.
Results: The total prevalence of oral mucosal lesions in the studied women were 3.8%. The most commonly affected age group was 40-49 years, followed by 30-39, 50-59 and 60-71 years, respectively. Considering the fertility variables, only menopause (P=0.047) and normal menopause (P=0.024) significantly related to the prevalence of oral mucosal lesions.
Conclusions: The findings of the present study provide information on the prevalence of the oral mucosal lesions considering fertility status in a large population-based study in Iran. With due attention to the higher prevalence of oral mucosal lesions in menopause women, an improved comprehension of oral manifestations at menopause and preventive and treatment approaches during this period should be programmed with health care services to meet the needs of patients deservingly.
