The oral hygiene is not relatively good cause of smoking, ignoring oral hygiene, not having enough self-care skills and independent living in case mental illness. Their grinding the teeth, serotonin decreases when the people are depressed and then it makes the carbohydrates increases, loses the sense of taste. Therefore they use a lot of sweet, the salivary output decreases, increase in the number of lactobacili and then it makes the cause ofabnormal disease detections including tooth decay, trigeminus neural pain in temporomandibular joint /TMJ/, oral yeast infection, oral bad breath, burning sensation of the tongue, chronic facial pain. Also the oral can disease detects from drug causes like using the anti-depression drugs for at least 6 months.Using analytical research permanent design, I got 55 patients to take part in the survey who are staying in 5th flat , National Clinic of Mental Health from 22nd of September 2014 until 26th of September. When I do the research for history of their patients: among the diagnosis of 16 people disorder depressed, the 13 patients agreed to have a preventive examination voluntary, one of them declined to do it. I use many methods of researching like questionnaire methods interview method, prevention oforal cavity and clinical examinations, respectively Study shows that curriculum contents of School of Nursing, Mongolian National University of Medical Sciences have comparatively less contents of understanding about healthy person, assessment on human, giving advice healthy human, path anatomy, physiology, communication skills.The most of the survey participant patients have holes in their teeth, gum inflammation, and tongue stress disorder. It shows that it decreased to pay attention on their oral hygiene associated with symptoms and it effects directly related to the decrease in salivary output.Depressed People are so bad at paying attention to their oral hygiene habits.

BACKGROUND. In the world, infertility occurs in 10-15% of the total couples and male infertility accounts for 40-50% of the infertile cases. Infertility frequency in Mongolia is 8.7% in 2003 and 11.6% in 2013. According to the Child and Maternity hospital study, 25.6% of infertility is due to men. Microdeletions of the Y chromosome long arm are the most common molecular genetic causes of severe infertility in men. They affect three regions including azoospermia factors (AZFa, AZFb and AZFc), which contain various genes involved in spermatogenesis. OBJECTIVES. The aim of the present study is to investigate the relationship between sexual hormones and AZF microdeletion on Y chromosome in Mongolian infertile men with azoospermia and severe oligozoospermia. MATERIAL AND METHODS. Through a cross sectional study, 50 infertile men were examined for Y chromosome microdeletions from January 2018 to August 2018. We determined hormone level, testis biopsy and microdeletions of the Y chromosome using six loci of 3 regions of the AZF gene were investigated by multiplex polymerase chain reaction. Semen analysis was performed on samples obtained by self-masturbation at the hospital after 2-7 days of sexual abstinence. Reproductive hormone level in serum including total testosterone, follicular stimulating hormone (FSH), and LH is measured at time 8 am to 11 am. If sperm is not recovered, testicular biopsy was performed on the patient. All collected datas were evaluated with Statistical Package for Social Sciences (SPSS, version 22.0). RESULTS. The rate of microdeletion was 4.0% (2 out of 50 patients). The deletion was on AZFa in the first patient, AZFc in the second patient. The patients with Y chromosome microdeletion had azoospermia. AZFa deleted patient has sertoli cell only syndrome in testis biopsy with FSH 58.0 mIU/ml, LH 12.0 mIU/ml, total testosterone 5.0 ng/ml. AZFc deleted patient had FSH 23.85 mIU/ml, LH 13.01 mIU/ml, total testosterone 4.06 ng/ml. Serum FSH and LH levels were significantly higher in Y chromosome deleted group and FSH level was significantly lower in sperm-retrieved group on TESE. СONCLUSION. We determined 2 cases of Y chromosome microdeletion (4.0%) in infertile men. Serum FSH and LH levels were significantly higher in Y chromosome deleted group.
