Effect of Temperature of 1.23% Acidulated Phosphate Fluoride Gel on Enamel Microhardness of Permanent Teeth.

This study aimed to assess the effect of temperature of 1.23% acidulated phosphate fluoride (APF) gel on enamel microhardness of permanent teeth. This in vitro experimental study was conducted on 36 surgically extracted impacted human third molars.

Management and Follow-Up of Complicated Crown Fractures with Intrusive Luxation of Maxillary Incisors in an 8-Year-Old Boy.

Intrusive luxation is a severe form of dental injury which causes damage to the pulp and supporting structures of a tooth because of its dislocation into the alveolar process. This paper shows the case of the reeruption of maxillary incisors accompanied by complicated crown fractures after 3 months. An 8-year-old boy patient was referred to the Department of Pedodontic Dentistry of Tehran University of Medical Science, Tehran, Iran, 18 hours after a fall at school.

Effect of Dentin Pretreatment with Chlorhexidine on Push-Out Bond Strength of Composite Restorations in Severely Damaged Primary Anterior Teeth.

Objectives: Achieving durable restorations with adequate strength in severely damaged primary anterior teeth in children is a priority. The aim of this study was to investigate the effect of dentin pretreatment with chlorhexidine on push-out bond strength of composite restorations.

Materials And Methods: In this in vitro experimental study, 56 extracted primary anterior teeth were randomly divided into 4 groups: (1) saline and total-etch bonding agent, (2) chlorhexidine and total-etch bonding agent, (3) saline and self-etch bonding agent, and (4) chlorhexidine and self-etch bonding agent.

Effect of Precuring and Postcuring of Total-Etch and Self-Etch Bonding Agents on the Microleakage of Fissure Sealants.

Objectives: Considering the importance of timesaving in pediatric dentistry, if the efficacy is achieved along with shorter working time and less technical sensitivity, the behavior management of young patients can be anticipated. This study aimed to compare the effect of precuring and postcuring of total-etch and self-etch bonding agents on the microleakage of sealants.

Materials And Methods: This study was conducted on forty impacted third molars, which were surgically extracted.

Coronal Sealing Capacity of Temporary Restorative Materials in Pediatric Dentistry: A Comparative Study.

Aims: The aim of this study is to compare the coronal microleakage of three common temporary restorative materials, namely Coltosol, Compoglass, and Zonalin, used in pediatric dentistry after endodontic treatment at different time intervals (1 week, 1, and 2 months) using dye penetration.

Materials And Methods: Access cavities were prepared in 72 intact extracted premolar teeth. The samples were divided into three groups (n = 24) and filled with Coltosol, Compoglass, or Zonalin.

A Comparative Study of the Effect of Prednisolone and Celecoxib on MMO (Maximum Mouth Opening) and Pain Following Removal of Impacted Mandibular Third Molars.

Objective: The purpose of this study was to compare the effects of prednisolone and celecoxib on pain and maximum mouth opening (MMO) after surgical removal of mandibular third molars.

Methods And Materials: This double-blind clinical study was conducted upon 60 subjects. These patients received 4 tablets of either 100 mg celecocxib or 5 mg prednisolone: one tablet before surgery and the rest for every 8 h post-operation.

Evaluation of hemodynamic and SpO2 variability during different stages of periodontal surgery.

Background: Changes in pulse rate and blood pressure are common consequences during oral surgeries. Hypoxia during surgical process is another side effect. The objective of the present study was evaluation of blood hemoglobin oxygenation and hemodynamic changes during periodontal surgery.
