Investigating the relationship between DMFT and mothers' knowledge and attitude about oral health and dmft of 6-12-year-old children with attention-deficit/hyperactivity disorder.

Background: Children with attention-deficit/hyperactivity disorder (ADHD) are more prone to tooth decay. In this regard, parents, especially their mothers, play a major role in the oral health of their children.

Materials And Methods: The present study was a cross-sectional descriptive study.

Rotary versus Manual Instrumentation for Root Canal Preparation in Primary Teeth: A Systematic Review and Meta-Analysis of Clinical Trials.

Objectives: The aim of this systematic review was to assess the scientific evidence on the effect of rotary versus manual instrumentation for root canal preparation in primary teeth.

Materials And Methods: Search terms were selected based on Medical Subject Headings (MeSH) and non-MeSH terms. Electronic database search of English published literature was performed in March 2020 within the following databases: Scopus, Cochrane, PubMed, and Embase.

Evaluation of teachers' knowledge about dental injuries in primary schoolchildren in the city of Isfahan.

Background: Dental trauma is a common problem in children, which mostly occurs at school. Traumatic dental injuries often cause unpleasant experiences for children, and immediate and appropriate measures are needed. Its prognosis depends on immediate posttraumatic measures, and schoolteachers can play a key role in the treatment of children.

Autistic children's parents and hospital dentistry.

Background: It is difficult to perform dental procedures in autistic children, and parental involvement is necessary for successful hospital dental services. Therefore, in order to promote oral health in autistic children, this study was aimed to explore the knowledge, attitude, and performance of autistic children's parents with respect to hospital dentistry.

Materials And Methods: This cross-sectional study was conducted with the parents of 100 autistic children aged 2-6 years selected from among the children of Isfahan autism treatment centers.

Comparison of the longevity of prefabricated and conventional band and loops in children's primary teeth.

Background: Prefabricated band and loops require only one appointment, are quickly placed in a session, and do not require laboratory work; thus, they need less time and cost. The aim of this study was to evaluate the survival rate of prefabricated band and loops in space maintenance of primary teeth and compare them with conventional band and loops.

Materials And Methods: In this prospective clinical trial study 4-9-year-old patients, who met the requirements of the present study, were divided into two groups.

Immunohistochemically Detection of Angiogenesis in Oral Pre-Cancerous Lesions Compared with Oral Invasive Carcinomas.

Background: Angiogenic activity is an important event in oral carcinogenesis. During transition of normal oral mucosa to different grades of dysplasia and to invasive carcinoma, significant increase of vascularity occurs. Angiogenesis can be determined by immunohistochemical assessment of several endothelial cell markers like Endogelin (CD 105), expressed in activated endothelial cells and associated with neovasculature, and the vascular endothelial growth factor (VEGF).

Bispectoral index scores of pediatric patients under dental treatment and recovery conditions: Study of children assigned for general anesthesia under propofol and isofloran regimes.

Background: This study was planned to determine the relationship between bispectoral index (BIS) during dental treatment and recovery conditions in children undergoing two regimes of anesthesia of propofol and isoflurane.

Materials And Methods: In this single-blind clinical trial study, 57 4-7-year-old healthy children who had been referred for dental treatment under general anesthesia between 60 and 90 min were selected by convenience sampling and assigned to two groups, after obtaining their parents' written consent. The anesthesia was induced by inhalation.

Comparative evaluation of bispectral index system after sedation with midazolam and propofol combined with remifentanil versus ketamine in uncooperative during dental procedures.

Background: Proper analgesic agents should be used in combination with sedative agents. Remifentanil is a synthetic narcotic/analgesic agent with a short duration effect and decreases the risk of apnea during recovery. Bispectral index system (BIS) is a new noninvasive technique for the evaluation of the depth of sedation.

Chondroectodermal dysplasia: a rare syndrome.

Chondroectodermal dysplasia (Ellis-Van Creveld syndrome) is a rare autosomal recessive congenital abnormality. This syndrome is characterized by a spectrum of clinical findings, among which chondrodystrophy, polydactyly, ectodermal dysplasia, and congenital cardiac anomalies are the most common. It is imperative to not overlook the cardiac complications in patients with this syndrome during dental procedures.

Diagnostic value of E-cadherin and fibronectin in differentiation between reactive mesothelial and adenocarcinoma cells in serous effusions.

Background: One of the problems in studying serous effusion cytological samples is differentiation of reactive mesothelial cells from metastatic adenocarcinoma cells.

Materials And Methods: In this study, the immunohistochemical diagnostic value of E-cadherin and fibronectin markers for differentiation of these 2 groups of cells was studied. 50 cell block samples prepared from serous effusions were examined.

Effect of storage environment on the bond strength of reattachment of crown fragments to fractured teeth.

Aim: The aim of this study was to examine various storage environments for storing fragments before being bonded to the remaining teeth and also estimate the required force to fracture the restored teeth.

Materials And Methods: Sixty mandibular incisor teeth were fractured on the incisal one-third and were divided into five groups of 12 each to be stored in normal saline, water, milk, saliva and dry environments for 24 hours. All the fractured parts in each group were bonded to their relevant apical parts by an etch and rinse bonding system and a flowable composite resin.
