Such structures have been described by Titus Livius in cuneiform written texts in 59 B.C. In 23 B.C. Caius Plinius Secundus the Elder thought that boys born with teeth were likely to have a bright future, while on the contrary, girls with natal teeth (= name given to those structures) were likely to live a disastrous life.

Research Article: Microbiological Evaluation of Toothbrushes Contamination while their using Period and Storage
Olga Fadeeva1* and Tatiana S. Stepanova2
Toothbrush, toothpaste and floss are an integral part of everyday life. Due to convenient packaging, toothpaste and floss do not provide conditions, suitable for microorganism's accumulation on their surface, which is not true for toothbrush. It gradually assembles plaque together with all contents. S. Taji and A. Rogers  revealed that in period of 3 weeks manual toothbrush accumulate critical level of microorganisms on its working surface, which is direct indication for its replacement.

Letter to Editor: Psychopharmacocorrection in the Complex Treatment of Patients with the Painful Dysfunction Syndrome of the Temporomandibular Joint
Anna N. Karelina1*, Sergey V. Stepanov2 and Marina S. Stepanova2
Dysfunction of the Temporomandibular Joint (TMJ) is one of the topical problems in Dentistry. On this pathology is reported in 14-20% of children, adolescents and 40-85% of adult population [1-4]. The syndrome of painful dysfunction of the TMJ is a polyethiologic disease, and the role of individual factors in the development and maintaining of this pathological condition is not clear enough understood. The focus is on the occlusal-articulatory [5,6] and myogenic [7,8] of the etiological concept. In recent years, the dominant influence of psychosocial factors on the development of the syndrome of painful dysfunction of the TMJ [7,9-14].

Research Article: Evaluation of Material Characteristics of Nano Particle Coated and Uncoated Stainless Steel, Nickel-Titanium and Beta-Titanium Orthodontic Archwire - an In-vitro Study
Murtaza Raotiwala, Rajaganesh Gautam, Ajit Kalia and Mohammed Shahid Hussain*
Introduction & Objectives: The characteristics desirable in an orthodontic archwire are a large springback, low stiffness, good formability, high stored energy, biocompatibility, environmental stability, resilience and low cost.
The Aim is to evaluate mechanical properties of Nanoparticles coated stainless steel archwire and to compare its mechanical property with that of uncoated stainless steel, NiTi and Beta Titanium orthodontic archwire for the parameters: Tensile strength, Elongation measurements, Bending tests, Hardness tests, Microscopic examination & Friction test.
Methodology: A self-lubricating metal coating containing nanoparticles is demonstrated. A universal testing machine/ Instron is used for testing tensile Strength, elongation measurements, bending and frictional resistances. A Reichert Austria make micro hardness tester and optical microscope is used for hardness tests & evaluation of microstructure.
Results: Descriptive statistical analysis was carried out to explore distribution of various parameters across coated and uncoated groups which will be discussed through tables and graphs.
Tensile strength increased in nanoparticles coated archwires and coated SS showed the highest tensile strength.
oated archwires showed decrease in Elongation/Strain test.
Bending test showed higher load deflection rates in coated wires and coated SS showed the highest load deflection rate.
Coating significantly increases the Micro-hardness of the archwires.
Frictional forces are reduced for coated archwires.
SEM Study shows less surface irregularities on coated orthodontic archwires.

Research Article: Dentin Demineralization Inhibition at Restoration Margins of Ionolux Resin-Modified Glass Ionomer Cement
Lauren M. Melendez* and Kevin J Donly
Purpose: To examine the in vitro caries inhibition of a resin-modified glass ionomer cement (Ionolux-VOCO) and a non-fluoridated resin control (Z 100, 3M ESPE).
Materials and Methods: Standardized Class V preparations were placed in 20 molars, the gingival margin placed below the cementoenamel junction. Randomly, 10 Ionolux, and 10 Z 100 restorations were placed according to manufacturer's instructions. All teeth had an acid-resistant varnish placed to within 1 mm of restoration margins and they were then subjected to an artificial caries challenge (pH 4.4) for 4 days. Sections of 100 microns were obtained, photographed under polarized light microscopy, and then digitized to quantitate demineralized areas adjacent to the restoration.
Results: The mean (+/- S.D) area (μm2) demineralization 100 microns from the dentin/gingival margin was: Ionolux 2,886 ± 3,211; Z 100 11,561 ± 2,655. A t-test indicated the Ionolux resin-modified glass ionomer cement had significantly (p > 0.001) less demineralization adjacent to restoration margins that the Z 100 resin-based composite control.
Clinical Significance: This study indicated that Ionolux resin-modified glass ionomer cement demonstrated caries inhibition at restoration dentin/cementum margins that was significantly greater than a no-fluoride-releasing resin-based composite control.
