Correlation of the Apgar Score with Dental Caries in 3- to 5-year-old Iranian Children.

Background: Dental caries is a serious health condition in children. Poor diet, poor oral hygiene, and unique anatomy of the primary teeth can all contribute to the development of caries in primary teeth. Developmental structural defects in teeth during the fetal period and the first year after birth are believed to increase caries susceptibility.

Comparative evaluation of anesthetic efficacy of inferior alveolar nerve block and inferior alveolar nerve block plus buccal or lingual infiltration using articaine in mandibular molars with irreversible pulpitis: a preliminary prospective randomized single-blind clinical trial.

Objectives: This study was designed as a prospective randomized single-blind clinical trial to compare the anesthetic efficacy of inferior alveolar nerve block (IANB), IANB plus buccal infiltration, and IANB plus lingual infiltration of 4% articaine with 1:100,000 epinephrine in mandibular molars with irreversible pulpitis.

Method And Materials: Sixty healthy volunteers who had a first or second mandibular molar diagnosed with irreversible pulpitis participated in the present study. This study was composed of three arms for the first molar and three arms for the second molar.

Effect of Root Dentin Pretreatment on Micro-Push-Out Bond Strength of Fiber Posts to Root Canal Dentin: Cold Atmospheric Argon Plasma (CAAP) and Ethylenediaminetetraacetic Acid (EDTA).

Purpose: Debonding from the root canal dentin is the most common failure mode of fiber posts. This study aimed to assess the effects of cold atmospheric argon plasma (CAAP) and ethylenediaminetetraacetic acid (EDTA) on micro-push-out bond strength of fiber posts to root canal dentin.

Materials And Methods: Forty maxillary canine teeth were decoronated, underwent endodontic treatment, and were stored in an incubator for 7 days.

Determining salivary and serum levels of iron, zinc and vitamin B in patients with geographic tongue.

Benign migratory glossitis or geographic tongue, whose cause still remains a mystery, emerges as annular lesions on the dorsal surface of the tongue. Several reasons have been reported for this condition, including vitamin deficiencies, digestive disorders, emotional stress and nutritional deficiencies. In order to introduce an efficient treatment for the geographic tongue, the present study investigated the levels of iron, zinc and vitamin B in the blood and saliva.

Effects of Erbium Family Laser on Shear Bond Strength of Composite to Dentin After Internal Bleaching.

The aim of this study was to assess the effect of surface treatment with erbium: yttrium-aluminum-garnet (Er:YAG) and erbium, chromium: yttrium-scandium-gallium-garnet (Er,Cr:YSGG) lasers on shear bond strength of composite resin to recently bleached dentin. In this study, 40 extracted human premolars were selected. The teeth were cut 4 mm apical to the cusp tip and were randomly divided into four groups (n=10 in each group) for shear bond strength testing.

Shear Bond Strength of a Resin Cement to Different Alloys Subjected to Various Surface Treatments.

Objectives: Micromechanical retention of resin cements to alloys is an important factor affecting the longevity of metal base restorations. This study aimed to compare the bond strength and etching pattern of a newly introduced experimental etchant gel namely Nano Met Etch with those of conventional surface treatment techniques for nickel-chrome (Ni-Cr) and high noble alloys.

Materials And Methods: A total of 120 discs (8×10×15 mm) were cast with Ni-Cr (n=20), high noble BegoStar (n=50) and gold coin alloys (n=50).

Antibiofilm efficacy of silver nanoparticles as a vehicle for calcium hydroxide medicament against Enterococcus faecalis.

Objectives: The aim of the present study was to investigate antibacterial characteristic and Enterococcus faecalis (E. faecalis) biofilm suppression effect of different vehicles of calcium hydroxide as intracanal medicaments in short and long-term.

Methods: Fifty-four human single-root teeth were contaminated with E.

The effect of remin pro and MI paste plus on bleached enamel surface roughness.

Objective: The growing demand for enhanced esthetic appearance has led to great developments in bleaching products. The exposure of hard tissues of the tooth to bleaching agents can affect the roughness of the enamel surface. The freshly bleached enamel surface exposed to various surface treatments such as fluoride and other remineralizing agents have been assessed in this study.

Orthodontic research output from iran in international and national journals.

Objective: The number of scientific papers is a conventional metric to measure a country's research performance in a particular area. The aim of this survey was to demonstrate statistical information about orthodontic research published in international and national journals.

Materials And Methods: Pubmed as an international and IranMedex and SID as national databases were searched between1997 and 2012.

Bone formation with two types of grafting materials: a histologic and histomorphometric study.

Background: Although autogenous bone grafts are considered the gold standard for bone regeneration, they have certain limitations, including patient morbidity at the harvest site. Synthetic bone substitutes have been developed to overcome some of these limitations. The present study aimed to compare the osteogenic properties of Straumann Bone Ceramic (SBC), which is a biphasic calcium phosphate, with Bio-Oss, an inorganic bovine bone material, in an animal model.

Comparison of pulpotomy with formocresol and MTA in primary molars: a systematic review and meta- analysis.

Introduction: There are various studies looking at the effects of formocresol (FC) and mineral trioxide aggregate (MTA) on pulpotomy of primary molars. This is a systematic review of literature comparing the success rates of MTA and FC in pulpotomy of primary molars.

Materials And Methods: The study list was obtained using PubMed, EMBASE, Scopus, Science Citation Index, Iran Medex, Google Scholar, the Cochrane Library, and also some hand searches contains through dental journals approved by the Iranian Ministry of Health.
