Relationship between Two Panoramic Radiography Indices and Bone Mineral Density of Postmenopausal Women with Osteopenia and Osteoporosis
Conclusion:The results showed that MCW is an appropriate index of osteoporosis in post-menopausal women. Although the prediction of osteoporosis is poorer at the femoral neck than lumbar.Key Words   Menopause; Mandibular Cortical Index; Mandibular Cortical Width; Osteoporosis; Osteopenia; (Source: Journal of Dentistry, Shiraz University of Medical Sciences)

Experimental Evaluation of the Effect of Zinc Salt on Inhibition of Streptococ-cus mutans
Conclusion:Zinc sulfate and zinc acetate salts with 37.19 and 31.25 µgr/mL concentration had inhibitory effect onStreptococcus mutansgrowth respectively, although, no priority in antibacterial activity of the studied zinc salts was determined in comparison with penicillin and chlorhexidine.Key Words   Zinc sulfate; Zinc acetate;  Streptococcus mutans  (Source: Journal of Dentistry, Shiraz University of Medical Sciences)

Myofibroma as a Rapidly Growing Gingival Mass in a 4-year-old Boy: a Case Report
This report presents a 4-year-old male patient with a rapidly growing mandibular gingival mass with some evidence of underlying alveolar bone destruction. Incisional biopsy was performed and the specimen was stained with hematoxylin and eosin and immunohistochemical antibodies for αSMA, CD34, S100 and desmin. The diagnosis of myofibroma was made and the lesion was completely excised. The knowledge about microscopic features of this rare neoplasm helps to have a proper diagnosis and avoid unnecessary treatment. (Source: Journal of Dentistry, Shiraz University of Medical Sciences)

Immune Thrombocytopenic Purpura Detected with Oral Hemorrhage: a Case Report
We report a case of ITP detected based on oral hemorrhagic symptoms. The patient was a 79-year-old female with no significant past medical history. She presented with sudden onset of gingival bleeding and hemorrhagic bullae on the buccal mucosa. Gingival bleeding was difficult to control. Laboratory tests revealed severe thrombocytopenia with a platelet count as low as 2000/ μL. Under a provisional diagnosis of a hematological disorder, she was referred to a hematologist. A peripheral smear showed normal-sized platelets. A bone marrow examination revealed increased numbers of megakaryocytes without morphologic abnormaliti...

Ergonomic Evaluation of Dental Professionals as Determined by Rapid Entire Body Assessment Method in 2014
Conclusion: It can be concluded that the work conditions and postures of dentists need to be improved. In addition, the level of dental professional education regarding the risk factors for musculoskeletal disorders as well as correct working conditions and postures should be promoted (Source: Journal of Dentistry, Shiraz University of Medical Sciences)

A Comparative Study of Macrophage Density in Odontogenic Cysts and Tumors with Diverse Clinical Behavior
Conclusion:The lack of significant differences in macrophage density between the known aggressive odontogenic tumors and much less aggressive lesions implied that macrophages might not contribute to the biological behavior of the odontogenic lesions. Therefore, it could support the notion that targeted therapy would not have prominent clinical potential to decrease the extent of mutilating surgeries in odontogenic lesions.

Comparison of the Bony Changes of TMJ in Patients With and Without TMD Complaints Using CBCT
Conclusion: By employing CBCT as a modern diagnostic imaging tool, findings of this study revealed that the frequency of various temporomandibular joint alterations on CBCT images is comparable in patients with and without TMD complaints, suggesting that some people with TMJ structural damage may not display clinical manifestations. Moreover, CBCT imaging might not be necessary for TMD patients and more attention should be given to clinical examination. (Source: Journal of Dentistry, Shiraz University of Medical Sciences)

Study of Extrinsic Apoptotic Pathway in Oral Pemphigus Vulgaris Using TNFR 1 and FasL Immunohistochemical Markers and TUNEL Technique
Conclusion: Apoptosis is probably is a preceding phenomenon to acantholysis in pemphigus vulgaris. It appears that the apoptosis occurs mostly by extrinsic pathway using proapototic mediators TNFR1 and FasL.   (Source: Journal of Dentistry, Shiraz University of Medical Sciences)

Comparison of Osteogenic and Chondrogenic Differentiation Ability of Buccal Fat Pad Derived Mesenchymal Stem Cells and Gingival Derived Cells
Conclusion:Based on the present results, BFP yields a greater proportion of stem cells compared to gingiva. Therefore, this tissue can be introduced as an easily available source for the treatment of periodontal defects and other maxillofacial injuries.

Immunohistochemical Study of p53 Expression in Patients with Erosive and Non-Erosive Oral Lichen Planus
Conclusion: The increased incidence of p53 from normal mucosa to erosive OLP indicated the difference between biological behavior of erosive and non-erosive OLP. It can be claimed that the erosive OLP has great premalignant potential compared with the non-erosive one. (Source: Journal of Dentistry, Shiraz University of Medical Sciences)

Arg753gln and Arg677 Trp Polymorphisms of Toll-Like Receptor 2 In Acute Apical Abscess
Conclusion:Arg677Trp polymorphism of TLR-2 rendered a higher risk for the development of abscesses in apical periodontitis. It is recommended to explore role of this polymorphism in other populations.  (Source: Journal of Dentistry, Shiraz University of Medical Sciences)

Factors Affecting Dental Caries of Preschool Children in Shiraz, 2014
Conclusion:The dental caries status of the studied preschool children was not desirable which could be indicative of the inadequacy of the current preventive programs. To improve this issue, interventional preventive programs such as tooth brushing are recommended. The programs are more necessary for the children of low socioeconomic families and those with poor oral hygiene habits. (Source: Journal of Dentistry, Shiraz University of Medical Sciences)

Comparative Evaluation of Penetration Ability of Three Pit and Fissure Sealants and Their Relationship with Fissure Patterns
Conclusion: U- type fissure pattern was more common than other fissure patterns and showed significantly higher penetrability of different type of sealants evaluated in the present study. GIC based sealant, due to significantly higher penetration depth than unfilled and filled sealants used in the present study, can be preferred over filled or unfilled resin sealants.
