Background: This study compared the safety and efficacy of nitrous oxide (NO)/midazolam and NO/promethazine for dental treatment of uncooperative children.
Materials And Methods: In this randomized, cross-over, clinical trial investigation Eighteen healthy uncooperative children with a pair of similar teeth requiring the same treatment were included. Combination of NO/midazolam was given in one visit, where NO/promethazine was administrated in the other appointment for each patient in a cross-over manner.
Objective: The purpose of this study was to evaluate the effect of different concentrations of platelet-rich plasma (PRP) on the proliferation of undifferentiated periodontal ligament (PDL) fibroblasts.
Materials And Methods: The undifferentiated PDL fibroblasts were obtained from two healthy human premolar teeth and cultured in Dulbecco's modified Eagle's medium. Cell wells were divided into five groups.
Objective: Adverse effects of dental materials, especially metals, have been an important issue in recent decades.
Purpose Of Study: The purpose of this study was to determine the amount of nickel released from stainless steel crowns in artificial saliva.
Materials And Methods: In this in-vitro study, 270 stainless steel crowns were divided into five groups, each with nine subgroups.
Objective: Providing a safe and efficient dental treatment for a young patient is a challenge for the dentist and the child. The purpose of this study was to investigate the effectiveness, safety and acceptability of buccal midazolam in dental pediatric patients and to compare it with oral Midazolam.
Methods: Eighteen uncooperative healthy children aged 2.
Objective: The prenatal period is the best time for health interventions. The aim of this study was to evaluate the effects of different methods of anticipatory guidance presentation on the change of knowledge and attitude of pregnant women regarding oral healthcare in the mother, infant and toddler.
Materials And Methods: In this quasi-experimental study, 90 pregnant women attended one health center in Zahedan, Iran; they were divided into direct intervention, indirect intervention and control groups.
Background: Attempts to enhance bond strength of the sealant have been among the most important sides of dental research.
Aim: The purpose of the present study was to evaluate the effect of using different rinsing angles on the micro-tensile bond strength of the sealant to the etched enamel.
Settings And Design: Experimental study.
Objective: Calcium fluoride deposit during fluoride application. Uptake and retention of fluoride by saliva depends generally on the concentration of calcium. In this study, the effect of calcium pre-rinse on salivary fluoride concentration after a 900 ppm fluoride mouthwash was investigated.

The purpose of the present study was to evaluate the effect of using different rinsing angles on the micro-tensile bond strength of the sealant to the etched enamel.
Materials And Methods: Sixty first-premolars were randomly assigned to six groups based on the rinsing angle applied (15°, 30°, 45°, 60°, 75° and 90°).
This paper presents a case with dentinogenesis imperfecta (DI) associated with osteogenesis imperfecta. Systemic and dental manifestations of OI and its medical and dental treatments are discussed in this paper. A 5-year-old child with the diagnosis of OI was referred to the Dental School of Shaid Beheshti University of Medical Sciences.

Methods: The study population comprised of 433 7-9 year olds, from four schools in Zahedan, Iran. Subjects were evaluated clinically by one examiner, and at a separate session, their mothers completed a coded medical history questionnaire.
Purpose: The purpose of this investigation was to evaluate the effect of residual tooth structure on the microleakage of stainless steel crowns cemented with glass ionomer on primary maxillary and mandibular first molars.
Methods: Thirty extracted primary molars were divided into 2 groups: group 1 included intact teeth; and group 2 included extensively carious samples. Each tooth received standard preparation, and each crown was luted with G-CEM on its specific specimen.
Objective: Bruxism is defined as the habitual nonfunctional forceful contact between occlusal tooth surfaces. The aim of this study was to determine the prevalence of bruxism and correlated factors in children referred to dental schools of Tehran, based on Parent's report.
Methods: This cross-sectional descriptive study was conducted on 600 4-12 year-old children with a mean age of 7.
