The precise changes in soft palate morphology are not well understood yet.Purpose: The aim of this study was to conduct a detailed cephalometric evaluation of the alterations taking place in position and morphology of the soft palate after treatment of class III skeletal deformity via different surgical procedures (i.e. mandibular setback, maxillary advancement, bimaxillarysurgery).Materials and Method: 120 consecutive patients who were diagnosed as having skeletal class III deformity were evaluated. All patients included in this study were adults who had completed their growth and had cephalograms within amonth prior to operation (T1) and 1 month to 9 months post-surgery (T2) taken in the natural head position. Patients were divided according to the type of surgery undertaken in three groups: group 1 combination of mandibular andmaxillary (bimaxillary), group 2 (mandibular setback) and group 3 (maxillary advancement) surgery. Soft palate length, depth and thickness were evaluated at both T1 and T2 in each group. The results were compared by paired t and onewayANOVA tests.Results: Soft palate length increased significantly in groups I and III ( p <0.05). Soft palate depth changed significantly in group II ( p <0.05). Soft palate thickness did not changed in any groups ( p >0.05).Conclusion: Soft palate morphology was changed after class III surgeries. Palatal length was increased after maxillary advancement or bimaxillary surgery whereas its depth was increased after mandibular setback or bimaxillary surgery.}, keywords = {}, url = {https://dentjods.sums.ac.ir/article_41199.html}, eprint = {https://dentjods.sums.ac.ir/article_41199_5542116e8ca6966200f0d07fd4a88449.pdf} } @article { author = {Chamani, G. and Zarei, MR. and Rad, M. and Darvishpoor Kakhki, H.}, title = {Clinical and Laboratory Findings of a Group of Iranian Patients with Oral Lichen Planus}, journal = {Journal of Dentistry}, volume = {13}, number = {1}, pages = {9-13}, year = {2012}, publisher = {Shiraz University of Medical Sciences}, issn = {2345-6485}, eissn = {2345-6418}, doi = {}, abstract = {Statement of Problem: Lichen planus (LP) is a chronic disease that affects skin and mucous membranes. Lesions of oral lichen planus (OLP) can persist for a long time. Varying prevalence rates of oral lichen planus have been reported in different parts of the world, while information regarding the epidemiology of this disease in Iran is incomplete.Purpose: This study was designed to evaluate the characteristics of oral lichen planus in a group of Iranian patients and compare the results with similar conducted studies in other populations.Materials and Method: In this descriptive study data were collected from charts of 158 patients In Kerman, Iran (1997-2005) over 8 consecutive years. For each patient, age at presentation, gender, chief complaint, duration of chief compliant, previous treatment, current medications, skin involvement and a complete medical history has been recorded. A number of possible etiologic factors and possible presence of diabetes or liver disease also analyzed. Laboratory evaluations consisted of glucose tolerance test (GTT) and liver function tests (LFT). This data were analyzed by SPSS version 12 statistical software. Results: The mean age of study population was 41.16 years. Subjects were predominantly female (65.1%). Liver function tests (LFT) were abnormal in 19.6% of cases. Disturbance of glucose metabolism and fasting blood sugar was also higher than normal limit in10.8% and 2.9 % of cases respectively. Atrophic-erosive lesions were found in 17 of the cases. In 50 patients the lesions were exclusively keratotic and in 91 the lesions were atrophic-erosive and keratotic. Most oral lesions were multifocal (88.6%), with the buccal mucosa being the most common location in each clinical form (87.3%). Duration of oral lesions ranged from 0.4 to 20 years with a mean of 1.54 year.Conclusion: This study showed that epidemiological and clinical features of the disease in Kerman are similar to those mentioned in literature.

Therefore an accurate and immediate treatment seems to be necessary. Nowadays, alternative treatments, such as probiotics, are considered because of the adverse side effects of chemical medications. Probiotics are alive organisms which can be used for medical purposes and are added to different kinds of diary such as yoghurt. Lactobacill Acidophilus (LA) was detected form human’s recourses many years ago and nowadays can be found in special kinds of milk, yoghurt, juice and food complementories.Purpose: In this study we are to compare the effect of conventional pasteurized and lactobacillus acidophilus- fortified pasteurized yoghurt on Candida Albicans in vitro.Materials and Method: Candida Albicans was isolated from 30 oral candidasis patients, cultured and prepared as standard suspension. Probiotic powder of LA in MRS Media after 24hrs led to 5×109 lactobacillus. LA- fortified yoghurt was prepared via adding lactobacills into 250 ml of pasteurized boiled milk after 8hrs in 37oc.We prepared 3 tubes and added standard suspension of Candida in each of them. Adding sterile yoghourt, conventional pasteurized yoghurt and LA-fortified yoghurt to the tubes respectively, we put them in 35oc incubator for 48 hrs. We added the content of each tube in Sabouraud agar media and incubated in 25oc for 72 hrs and then counted the colonies.Results: There was a significant difference between the mean of colonies in each group during 5 days ( p = 0, df = 4) and also on each day ( p = 0, df = 2).Conclusion: L.A. can inhibit colonization of Candida in vitro.

Recent studies showthatshow that midface fractures are strongly associated with patient's death. The exact relationship between different types of facial fractures and brain injuries is still controversial. Purpose: To evaluate individuals with midface fractures from different causes and determine if there is any relationship between various midface fractures and brain injuries. Materials and Methods: In this descriptive cross-sectional retrospective study, we assessed the hospital charts of all the patients with midface fractures at the trauma center of Poursina hospital. The complete medical record of each patient was reviewed. The etiologic and demographic data, the type of midface fracture and brain injury, and Glasgow coma scale (GCS) were assessed. The data were analyzed by, the Chi-square, and the Fisher’s exact tests. The statistical package SPSS was used for all the analyses.Results: Of all the patients 47% had brain injury. The Important significant resultscorrelations were as follows: Le Fort II with Subdural Hematoma ( p =0.001), Brain Contusion ( p =0.049), Intracranial Hemorrhage ( p =0.001), Le Fort III with Subdural He-matoma ( p =0.001), Brain Contusion ( p =0.0001), nasal orbital ethmoid fractures  with subdural hematoma ( p =0.0001), Epidural Hematoma ( p =0.003), frontal fracture with subdural hematoma ( p =0.0001), Intracranial Hemorrhage ( p =0.024). Zygomatic complex fracture with Brain Con-tusion ( p =0.009). Nasal fracture correlated with  Subdural Hematoma ( p =0.01) and Brain Contusion   ( p =0.0001). The zygomatic complex fracture was the most prevalent fracture.Conclusion: Different midface fracture patterns have the risk of brain injury simultaneously. So midface fractures need more attention.

Recognition of the orofacial manifestations of neurological diseases is in direct relation with the responsibilities of a dentist.Purpose: The objective of this study was to familiarize dentists and even physicians with orofacial manifestations of related neurological diseases.Materials and Method: This cross- sectional study was performed on 1284 patients with known cases of neurological diseases referred from all over the Southern Provinces of Iran to Oral Medicine Department of Shiraz Dental School from 1997 to 2010. Orofacial manifestations of 34 different types of neurological diseases were classified in four main groups of cranial nerve disorders, main neurological disorders, neoplastic and tumoral neurological lesions and congenital anomalies of neurological disease. These groups were evaluated with respect to age, sex, signs and symptoms, clinical appearance and location of the lesions. Data were analyzed by using SPSS software version 15, by using relative frequency and frequency quotients.Results: Orofacial manifestations were shown in 532 patients of the first group (41.48%), 386 patients of the second group (30.11%), 243 patients of the third group (18.93%) and 123 patients of the fourth group (9.48%), respectively.Conclusion: According to the results of this 14 years study, cranial nerve disorders showed most of oral signs and symptoms followed by main neurological disorders, neoplastic and tumoral lesions, and congenital anomalies of neurological diseases respectively.

All clinical and paraclinical variables related to sever head and neck infections of odontogenic origin have not been fully evaluated.Purpose: This study was designed to identify the potential risk factors associated with increasing hospital stay in patients with deep head and neck spaces infections of odontogenic origin.Materials and Method: A total of 297 patients admitted to Shiraz Khalili hospital (1996-2006) with head and neck spaces infection were retrospectively identified by a medical chart view. Data concerning patient demographics, source and location of infection, culture results, and treatment modalities were evaluated. Linear regression techniques were used to explain the relationship between patient admission characteristics and duration of hospitalization.Results: A total of 34.3 % (n=102) of the patients had head and neck spaces infections of odontogenic origin. The most common location of infection was submandibular space (32%), followed by masseter space (22%) and Ludwig’s angina (20%). Culture results showed non-hemolytic streptococcus as the most common microorganism with the prevalence of 61.6%.The most frequent signs and symptoms were swelling and pain. The results showed a higher percentage of hospital admissions for the middle socioeconomic status (58.8%). Variables such as high weight, blood sodium level less than 135, preexisting disease and increasing in blood mean cell volume (MCV) were associated with longer hospital stay. Only 1 (0.9%) death was reported as the result of these infections.Conclusion: Odontogenic infections were a common source of deep head and neck spaces infection resulted in longer hospital stay.
