[Effect of verbal explanation in reduction of dental stress before third molar operation]

Background and Objectives: Most people fail to have necessary dental care because they're anxious to go to the dentist due to lack of the knowledge about dental procedures. The aim of this study was to evaluate the effect of verbal explanation in reduction of dental stress before third molar operation

Materials and Methods: This study designed as controlled clinical trial. Totally 60 patients selected from those referred to the oral and maxillofacial surgery department, dental faculty of Tabriz. After verbal expranation, the questionnaire consisted of demographic characteristics [age, education, life status, number of dental visits before surgery] and mean of pain according to visual analogue scale [VAS] was recorded. Data were analyzed by descriptive statistics [mean +/- SD], T-test and chi-square test by using SPSS.20 [P<0.05]

Results: Based on VAS scale, the mean of stress in control group was higher than test group [5.91 vs. 4.22 before surgery] and 5.61 vs. 3.115 after surgery] [P<0.05]. The difference between age, gender, education, life status and hospitalization was not statically significant between the control and test groups

Conclusion: Verbal explanation can reduce the stress level in patients undergoing third molar operation

[ success rate of inferior alveolar nerve and mandibular foramen anesthesia with and without panoramic radiography]

Background and Objectives: Inferior alveolar nerve block [IANB] is commonly applied for anesthesia of lower jaw but because of its anatomical location. The success rate of IANB is low. According to the fact that most of patients have radiography when refer to the dentists, we compared the success rate of anesthesia with or without using radiography to make IANB

Materials and Methods: In this study the patients referred to the maxillofacial department of Tabriz faculty of dessistry between 2011-2012 were included. At the first stage IANB was performed without using radiography and at the second stage we used radiography. Finally the success rate of this two methods were compared

Results: Thirty one [12 female -19 male] patients with mean age of 37.16 +/- 10.47 were included in this study. We found statistically significant difference between the success rate of this two methods [p=0.02]

Conclusion: Using radiography significantly success rate of IANB injection
