Towards a New Era in the Management of Large Periapical Lesion in Permanent Tooth Using Stemcells: A 2-Year Clinical Application Report
Stem cells are considered as the principal source of differentiated cells. In the past few years, the research on the stem cell in various fields had shown success, but the stem cell-based therapies in the dentistry had confined to a particular extent. The present case report was aimed to evaluate the efficacy of stem cells from human exfoliated deciduous teeth (SHED) in the management of a large periapical lesion. A 12-year-old girl reported with a chief complaint of pain in the lower right back tooth region since 5 days. Intraoral examination revealed a deep occlusal cavity in relation to tooth#46 with tenderness on perc...

Outcome of Surgery as Sole Treatment of Eosinophilic Granuloma of Jaws
Langerhans cell histiocytosis (LCH) is characterized by the congregation of proliferating langerhans cells (LC). Langerhans cells are a part of dendritic cell system of primary immune response that is responsible for presenting antigen to lymphocytes. Being a rare disease, the total incidence of LCH is reported to be 1 in 2 million people. LCH mainly affects children and young adults, with a slight male predilection. LCH is clinically divided into three groups namely Letter-Siwe disease (multiple multi organ affecting LCH at very young age), Hand-Schuler-Christian disease (LCH of bone involvement exophthalmos and diabetes ...

Periodontal Condition in Patients with Rheumatoid Arthritis: Effect of Anti-rheumatic Drugs
Conclusion:Periodontitis and clinical attachment loss were more in patients with rheumatoid arthritis than the healthy group, especially in drug consumers. Gingival index in patients without the history of consuming anti-rheumatic drugs was significantly higher than those who were drug consumers, indicating the effect of the medications on the signs of inflammation.

Ultrastructural and Chemical Composition of Dentin and Enamel in Lab Animals
Conclusion: The recorded details and the measured values indicate great resemblance between dog and human dentin and enamel. Cat is in the second place for dentinal studies; sheep and guinea pig have the least resemblance to human within the scope of the reviewed criteria.

The Effectiveness of Nigella Sativa Alcoholic Extract on the Inhibition of Candida Albicans Colonization and Formation of Plaque on Acrylic Denture Plates: an In Vitro Study
Conclusion:Nigella sativaextract at definite concentration is capable of clearing dental prosthesis, but compared to nystatin, it is weaker. However, due to the indirect immune-regulatory effects ofNigella sativa, it is suggested that other studies be conducted to investigate the therapeutic properties ofNigella sativafrom the aspects of antimicrobial, anti-inflammatory, and oral ulcer healing in candida oral lesions.

Expression of Paxillin in Benign and Malignant Salivary Gland Tumors
Conclusion: High expression of paxillin was observed in tumoral tissues compared with the controls that establish an important role of paxillin in SGTs but its prognostic role was unclear and need further evaluation. (Source: Journal of Dentistry, Shiraz University of Medical Sciences)

Correlation between Skeletal Age and Metacarpal Bones and Metacarpophalangeal Joints Dimensions
Conclusion: Regarding Pearson correlation, metacarpophalangeal joints length, metacarpal bones length, metacarpophalangeal joints width, and metacarpal bones width showed significant relationship with Bone Age, respectively.These measurements can be used as accessory criteria for bone age assessment using left hand radiography, to reduce inter-observer reading differences.Statement of the Problem: Currently, two major methods have been introduced for bone age assessment using left hand radiography. The first approach is Greulich and Pyle, which is very subjective. The second method is Tanner and Whitehouse, which is very t...

Intra- socket Transplantation of Bicuspid to Re-establish Biologic Width
This report describes a case of intra- alveolar transplantation of tooth #43 in a 35- year-old man. Clinical and radiographic examinations revealed tooth #43 with complicated crown-root fracture that had undergone endodontic treatment five months earlier. Reposition of mandibular bicuspid in its socket to re-establish biologic width and crown ferrule is an alternative treatment in cases with complicated crown-root fracture. Immediate replantation preserve viability of periodontal ligament cells and fibers attachment and good chance of healing is predicted.
