Perforations might occur due to carious lesions, tooth resorption or they might be iatrogenic during endodontic treatment or in most cases they might occur during post space preparation. CASE REPORT: A 31-year-old female patient presented with a complaint of chronic pain on tooth #30 during last 6 months and sensitive to bite since a few days ago. There was a mild swelling on the gingival tissu...

Based on radiation modes and phase relations in di€erent ARROW structures, the characteristic equations are presented that can avoid root searching in the complex plane and ®nd the e€ective index, loss and ®eld pro®le easily. This simple model gives an accurate intuitive picture for low loss leaky modes and it can be used to design and optimize the low loss ARROW devices of practical interest.

The scalar roughness for sensible heat ̄ux, z0h, which appears in Monin and Obukhov similarity theory has been shown to exhibit substantial variability. Brutsaert and Sugita (cf. W. Brutsaert and M. Sugita, J. Atmos. Sci. 53 (1996) 209±16) derived an expression for z0h to account for variability in z0h as a result anisothermal vegetation skin temperature, which assumes an exponential pro®le of ...

BACKGROUND Pluchea indica (L.) Less. (Asteraceae) is a perennial shrub plant with anti-inflammatory and antioxidant medicinal properties. However, the anti-cancer properties of its aqueous extracts have not been studied. The aim of this study was to investigate the anti-proliferation, anti-migration, and pro-apoptotic properties of crude aqueous extracts of P. indica leaf and root on human mali...

Pseudomonas fluorescens Pf0-1 showed positive chemotactic responses toward 20 commonly-occurring l-amino acids. Genomic analysis revealed that P. fluorescens Pf0-1 possesses three genes (Pfl01_0124, Pfl01_0354, and Pfl01_4431) homologous to the Pseudomonas aeruginosa PAO1 pctA gene, which has been identified as a chemotaxis sensory protein for amino acids. When Pf01_4431, Pfl01_0124, and Pfl01_...

OBJECTIVE The aim of periodontal therapy is the healing of periodontal inflammation; the protection of the attachment and the alveolar bone; and the regeneration of the periodontal structures. In the therapy of periodontitis, supra- and subgingival scaling and root planing plays a main role. The procedure described combines perfect root cleaning without scaling and root planing and minimal inva...

The rationale of this study was to assess the results of training endodontic to postgraduates. This study was assumed to evaluate the procedural quality of root canal obturation and occurrence of ritual errors in the root canal treatment cases performed by postgraduates in the department of Operative Dentistry. Study Design: Cross sectional case series study. Setting: Department Operative Denti...

OBJECTIVES The purpose of this study was to analyze how anti-infectious periodontal treatment affects C reactive protein (CRP) values in patients with type 1 diabetes, and correlate baseline CRP levels with periodontal disease severity. STUDY DESIGN A cohort of fifty three subjects with type 1 diabetes and moderate to severe periodontitis were recruited. Periodontal parameters were measured, ...

A public health crisis in the process of brownfield land redevelopment (BLR) has frequently appeared in the context of promoting industrial upgrading and de-industrialization in China. Recent discussions on the reasons for this problem centered on the lack of laws, standards, and policies needed to secure the process of BLR. However, we argue that an urban governance approach to BLR can identif...
