Influence of Various Desensitizing Mouthrinses and Simulated Toothbrushing on Surface Roughness and Microhardness of Tetric N-Ceram Bulk-Fill Resin Composite: An In Vitro Study and Scanning Electron Microscope Analysis.

Objectives:  Bulk-filled composite resins are popularly used for posterior restorations due to various advantages. Routine oral hygiene measures like toothbrushing and the use of various mouthrinses can influence the mechanical properties of composite resins. Desensitizing mouthrinses are widely used as well, to manage dentinal hypersensitivity.

Evaluation of Antioxidant Property of Amla on Bond Strength and Color Stability of Power Bleached Teeth: An Study.

Introduction: Objective: To assess the antioxidant property of 10% amla extract in reversing the compromised bond strength and to assess the antioxidant property of 10% amla extract and Elsenz on the color stability of power bleached teeth.

Materials And Methods: Ninty extracted single-rooted maxillary anterior were collected and divided as follows: The labial surfaces of 30 samples were subjected to power bleaching after which the samples were divided into three groups- Group I (control), Group II (antioxidant amla), and Group III (Elsenz) with = 10 in each which were then stained with a coffee solution for 10 mins. The color difference was recorded with a colorimeter at baseline, after bleaching, after 7, and after 15 days of staining.

Comparative evaluation of sealing ability of glass ionomer-resin continuum as root-end filling materials: An in vitro study.

Background And Objectives: Root-end filling is a prudent procedure aimed at sealing the root canal to prevent penetration of tissue fluids into the root canals. An ideal root-end filling material should produce a complete apical seal. Therefore, the aim of this study is to compare the leakage behavior of four different root-end filling materials.

Effect of power bleaching on the fluorosis stained anterior teeth case series.

Bleaching is a conservative method for restoring the colour of intrinsic discoloration of teeth. The combination of McInnes solution and power bleaching is effective procedure for bleaching of fluorosis stained teeth. Definitely bleaching with McInnes bleaching agent gives instant results, not dependent on patient's compliance as other office based procedures, no dehydration of the tooth occurs with no damage to the pulp.

Effects of commonly consumed beverages on surface roughness and color stability of the nano, microhybrid and hybrid composite resins: an in vitro study.

Background: Consumption of certain beverages may affect the esthetic and physical properties of the resin composite, thereby undermining the quality of restorations.

Aim: To analyze the effect of three beverages (cola, coffee, tea) on color stability and surface roughness of three different types of resin composites at various time intervals in vitro.

Materials And Methods: Nano, microhybrid and hybrid resin composites were used.

Management of chronic luxated central incisor with hopeless prognosis.

Traumatic injuries are the most studied yet most challenging for a dentist. Extrusive luxation injuries are usually managed by repositioning tooth in the original position and pulp sensibility is evaluated at regular periodic intervals. However, when injuries are chronic, tooth is necrotic with compromised periodontal support, treatment is a challenge.

A pioneering study of dental fluorosis in the libyan population.

Background: Fluorosis is a condition resulting from excessive ingestion of fluoride during early childhood leading to the formation of defective enamel. The increased fluoride content is thought to result in a metabolic alteration of ameloblasts, which results in defective matrix, and improper calcification of teeth.

Materials And Methods: A total of 6244 patients between the ages of 6yrs to 60yrs, who presented to our outpatient clinic from October 2009 to December 2010 were included in the study.

A comparative evaluation of the vertical root fracture resistance of endodontically treated teeth using different root canal sealers: an in vitro study.

Objective: The objective of this study is to evaluate the vertical root fracture resistance of endodontically treated teeth obturated with - Tubli-Seal EWT/Gutta-percha, AH Plus/Gutta-percha, Epiphany SE sealer/Epiphany point.

Study Design: Sixty-five single rooted premolars were decoronated and root length was 14 mm for each specimen. Fifty five teeth were enlarged up to ISO size 40 master apical file with stainless steel K-files using standardized preparation and remaining ten teeth were served as negative control.
