case of gingival myiasis caused by Wohlfahrtia magnified

A gingival myiasis in a four years old mental retarded boy with anorexia and weight loss is presented from southern part of Iran. Entomological studies on larvae showed the larvae as Wohlfartia magnifica which is a rare causative agent of gingival myiasis

frequency of trigeminal neuralgia in multiple sclerosis patients referred to Iranian MS Association during 2004-2005

It has been reported that some patients with multiple sclerosis may develop trigeminal neuralgia [TN] that may cause the loss of patient's intact teeth when incorrectly diagnosed by dentists. This study was conducted with the aim of assessing the frequency of trigeminal neuralgia in MS patients who were referred to the Iranian MS Association during 2004-2005. This descriptive cross-sectional study was conducted on 179 MS patients whose diagnosis was confirmed by MRI protocol. Patients were selected randomly among those who participated in educational courses at the Iranian MS Association. The data was collected by questionnaire, interview and clinical examinations. The collected information was analyzed by student-t and fisher's exact tests. The study showed that 7.8% of MS patients to have definitive signs of TN while detection of such involvement was not so clear in 2.8% of cases. About 76.5% of all patients were females and the rest [23.5%] were males. About 36.8% of TN patients showed some manifestations in the maxilla, 31.6% in the eye region, and 21.1% in the mandible. About 10.5% of the manifestations have occurred in the right side, 47.4% in the left and 42.1% in both sides. Seven patients [36.8%] demonstrated with trigger zones. Only about 10.6% of studied MS patients demonstrated trigeminal neuralgia. The ratio of TN development in patients with history of Baclofen usage was less than nonusers

Comparison of the effect of sugarfree orbit chewing gum and natural turpentine on salivary flow rate and pH

Medications, systemic diseases, head and neck radiotherapy and mental stress reduce the salivary flow rate and dispose one to dental caries and oral disease. There are different ways to compensate reduction of salivary flow rate such as sour c and ies, lemon, special stimulating sprays or lacques and chewing gums. Many factories such as Wrigly factory producing chewing gums claim to reduce caries rate by increasing salivary flow pH and after chewing their product. The purpose of this research was to compare the effect of sugarfree Orbit chewing gum and natural turpentine on the salivary flow rate and pH. This single blind r and omized clinical trial was accomplished on 16 dental students of Shaheed Beheshti University in 1383 using a cross - over method. The samples were selected by simple non - r and omized method divided into two groups, A and B each including eight persons. The saliva of all samples were collected 5 minutes after eating 2 sweet biscuits by active method during 10 minutes. Then the volume of collected saliva was measured and immediately the pH was determined by a calibrated pH meter. After 72h wash out period, on the 3rd day two biscuits were given to all of the samples and after 5 minutes 14 grams of sugarfree Orbit gum was given to samples of group B, the amount of saliva collected during 10 minutes measured, and the pH was resigtered. Again, after 72 h washed out period, on the 3rd day, two biscuits were given to all of the samples and after 5 minutes 14 grams of sugarfree Orbit was given to members of group B and equal amount of Turpentine to members of group A during 10 minutes of chewing. The amount of saliva and its pH was measured and registered again. The data were analyzed with sphericity and Friedman tests. The mean saliva flow rate after having the biscuits, chewing the gum and Turpentine was 5.0 +/- 0.8 ml, 15.8 +/- 1.0 ml, 13.7 +/- 1.3 ml, respectively. The difference among three groups was statistically significant [P<0.005]. The mean salivary pH at the beginning was 5.8 +/- 0.6 and after using gum and turpentine turned to 7.4 +/- 0.5 and 7.1 +/- 0.3. All of these amounts had a statistically significant difference [P<0.001]. Sugarfree Orbit chewing gum causes increase of saliva flow rate and its pH. Therefore, preventing the mouth diseases, caused by Xerostomia and teeth diseases
