1.  Effectiveness of Lasers in the Treatment of Dentin Hypersensitivity 
Dentin hypersensitivity (DH) is a relatively common painful condition among dental problems. Although many studies have been performed regarding the diagnosis and treatment of DH, dental practitioners are still confused about the definite diagnosis and treatment.The use of lasers as a treatment for dentin hypersensitivity was first introduced in 1985.Laser treatment in dentin hypersensitivity is an interesting and controversial issue and many investigations have been done on its mechanism of action, advantages, and unclear points.The present literature review tries to go over the definition, diagnosis, etiology , predisposing factors, various laser types in the treatment of DH alone or in combination with topical desensitizing agents. Since a certain treatment has not yet introduced for dentin hypersensitivity, a combination of laser therapy and topical desensitizing factors ,can increase the success of the treatment compared with either treatments alone.

2.  The prevalence of hypertension among the elderly in patients in Al-Zahra Hospital, Isfahan, Iran 
ARYA Atherosclerosis  2012;8(1):1-4.
In this study, we discussed aging and common diseases associated with it which can lead to hospitalization. Hypertension was also evaluated as one of the factors affecting morbidity and mortality in elderly people.
In this cross-sectional study, data was collected using checklists and extracting information from medical records in Al-Zahra Hospital (Isfahan, Iran). Data was then analyzed using descriptive statistics according to the research questions in SPSS.
A total number of 11,018 people aged 60-99 years were studied. Cardiovascular diseases were the most common cause of hospitalization [2063 patients (18.7%)]. In patients with cardiovascular diseases, 84 were suffering from hypertension, 76 had primary hypertension, 7 had hypertensive heart disease with or without congestive heart failure, and 1 had secondary hypertension. Among all hypertensive patients, there were 37 males (44.05%) and 47 females (55.95%). Moreover, 34 people aged 60-69, 30 aged 70-79, 18 aged 80-89 and 2 aged 90-99 years. Duration of hospitalization was less than 1 day for 12 people, 1-2 days for 27, 3-5 days for 25, 6-10 days for 14, 15-11 days for 6, and more than 15 days for 1 person.
Prevention and treatment of hypertension is important in order to control this disease. Untreated or poorly/untimely controlled hypertension would thus leave permanent side effects. It may thus leave sustained side effects if remain untreated or poorly/untimely controlled. However, people with hypertension were in minority in our study. Therefore, more research in this field with larger sample size is necessary for further identification of factors affecting quality of life in elderly people.
