[ 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

Comparison of the results of orbital floor reconstruction using different materials

Complications of orbital floor reconstruction is a big challenge for patients and specialists. The purpose of this study was to investigate the results and complications of the orbital floor reconstruction using different materials and to compare them. In This Retrospective study consisted of 12 cases with orbital floor fractures treated at Imam Reza Hospital of Tabriz Medical University, Iran, between June 2012 and May 2013. Patients' clinical data were retrospectively analyzed for gender, age, reconstruction material, and complications. Autogenous bone, Nasal septum, titanium mesh, and Medpor were implanted under the periosteum of the orbital floor in 3,2,4 and 3 cases respectively. All of the patients except 3 cases, showed satisfactory appearance. Diplopia and limitation of globe movement were resolved in 50% of the cases. Complete infraorbital nerve recovery were observed in 2 cases after 8 weeks. Subciliary incision was adopted in our surgery. There was no statistically significant difference among groups of patients in regard to the effectiveness of treatment using different materials. Appropriate diagnosis, early intervention, proper material selection and accurate orbital floor reconstruction were the key factors for successful treatment

An asymptomatic giant sialolith of the submandibular gland [case report]

Sialolithiasis is the formation of a calcified obstruction within the salivary duct. It may form in any of the major or minor salivary glands or their ducts. Overall, 80% to 90% of salivary gland stones occur in the submandibular gland. Sialoliths commonly measure from 5 to 10 mm in size and all stones over 10 mm can be reported as sialoliths of unusual size. In this study, we report a large sialolith presenting without clinical symptoms. The CBCT images of a 52-year-old man who referred for implant treatment evaluation of lower jaw showed a large radiopaque mass in floor of mouth. The patient did not have any history of pain or pus, and this sialolith was not his chief complaint. The sialolith was surgically removed. Some sialoliths, despite their remarkable size, can be a diagnostic and therapeutic challenge for the clinician. Appropriate diagnosis and treatment with minimal side effects is very important

Clinical results of localized alveolar ridge augmentation with bone grafts harvested from symphysis in comparison with ramus

Autogenous onlay bone grafting is a common procedure for alveolar ridge augmentation. It has been suggested that the amount of healed bone after this technique would be significantly less than the initial quantity. The aim of this study was to determine the relationship between the various parameters influencing the outcome of ridge augmentation procedures. Thirty-two patients, 17 males and 15 females [mean age 40 +/- 8.66], requiring lateral ridge augmentation in the anterior maxilla were recruited. Bone grafts obtained from either the mandibular ramus or symphysis were grafted on the recipient site and the buccolingual dimensions of the edentulous ridge before and six months after the procedure were measured and the difference between them was considered as ridge augmentation [RA]. Parameters including graft thickness [GT], graft area [GA] and donor site [DS] were also recorded. Onlay bone grafts, taken from mandibular and symphysis areas, significantly increased the buccolingual dimension of the alveolar ridge [mean 1.98 +/- 1.22 mm, p < 0.001]. However, the mean RA by symphysis grafts was significantly greater than ramus grafts [2.49 mm vs. 1.48 mm]. There was also a significant correlation between graft thickness, surface area and the amount of bone augmentation. Symphysis area provides thicker and larger grafts, which may result in a better clinical outcome in alveolar ridge augmentation

Evaluation of glove damage during dental procedures among dental specialists in Tabriz

Dental practitioners are prone to occupational risk of infection. This can be prevented in part by wearing gloves. However, for this to be effective, gloves should be intact during the entire course of dental procedure. Leaky surgical latex gloves have been seen in 0.9% of cases before use. As much as 1.9% of latex gloves have been reported to be damaged during dental procedures. In this study, we decided to assess glove damage during dental procedures among dental specialists in Tabriz. Thirty-six dental specialists were selected for this study. Each practitioner received 40 pairs of intact powdered latex gloves. Upon the completion of dental procedures, the gloves were retrieved and any tears were evaluated separately for right and left hands. Data was analyzed using chi-square test. 159 punctures were detected in 144 gloves [5%] out of 2880 unpaired gloves used by practitioners. They noticed the tear[s] in 60 cases [2%], however, 99 cases [3%] of tear[s] were not noted during the procedure. The highest rate of glove damage was observed in the prosthodontists' group [12.3%], which was statistically significant comparing to other groups [p=0.048]. The lowest rate of the damage was observed in the oral surgeons' group [2%] which showed no significant difference [p=0.134]. The highest rate of punctures in the gloves was observed in the first and second fingers of the non-dominant hand. The damage to 5% of the gloves is highly significant, with a potential role in occupational hazards. The higher rate of leaks in the prosthodontists' group compared to other groups demands for greater prudence in this field. The high rate of leaks in the first and second fingers of the non-dominant hand requires more attention to this area during daily practice
