ABSTRACTIntroduction: Early childhood Caries is a distressing situation for patients andparents and pediatric dentists. Aim: current research was carried out to evaluatefracture resistance bond strength different types of dentin posts compared tofiber posts. Materials Methods: This Current in-vitro study conducted on48 extracted primary incisors. Samples were split randomly into 4 groups 12 for...

introduction: dentin hypersensitivity is one of the most common complications that affect patients after periodontal therapy. recently low level laser therapy has been introduced as a new treatment modality and has produced beneficial results. the purpose of this study is to evaluate the effect of low level laser therapy toothbrushes in reduction of dentin hypersensitivity. methods: in this pil...

This paper presents the dental findings of a child with the oculocerebrorenal syndrome of Lowe. The genetic abnormality in this condition results in an inborn error of inositol phosphate metabolism. Renal tubular dysfunction leads to metabolic acidosis and phosphaturia. At 4 years, generalised mobility of all primary teeth was noted. It is postulated that a defective inositol phosphate metaboli...

The purpose of this study was to compare the effect hemostatic agent containing aluminum chloride with ferric sulfate on shear bond strength resin-modified glass ionomer cement(RMGIC) dentin in primary tooth. Twenty extracted non-carious human teeth were collected study. specimens cut expose and polished. randomly seperated into 3 groups for treatment; group I: polyacrylic acid(PAA), RMGIC; II:...

Our previous studies have demonstrated that nuclear factor I-C (NFI-C) null mice developed short molar roots that contain aberrant odontoblasts and abnormal dentin formation. Based on these findings, we performed studies to elucidate the function of NFI-C in odontoblasts. Initial studies demonstrated that aberrant odontoblasts become dissociated and trapped in an osteodentin-like mineralized ti...

OBJECTIVES This study investigated whether increasing the concentration of acidic monomers in one-step adhesives would allow reducing their application time without interfering with the bonding ability to primary enamel and dentin. MATERIAL AND METHODS Experimental one-step self-etch adhesives were formulated with 5 wt% (AD5), 20 wt% (AD20), or 35 wt% (AD35) acidic monomer. The adhesives were...

Classic embryological studies have documented the inductive role of root dentin on adjacent periodontal ligament differentiation.  The biochemical composition of root dentin includes collagens and cleavage products of dentin sialophosphoprotein (DSPP), such as dentin sialoprotein (DSP).  The high abundance of DSP in root dentin prompted us to ask the question whether DSP or peptides derived the...

Aim The Self-Adjusting File (SAF) system has been recommended for use in permanent teeth since it offers more conservative and effective root-canal preparation when compared to traditional rotary systems. However, no study had evaluated the usage of SAF in primary teeth. The aim of this study was to evaluate and compare the use of SAF, K file (manual instrumentation) and Profile (traditional ro...

this study aimed to assess the effect of chloroform, eucalyptol and orange oil solvents on the microhardness of human root dentin.sixty-eight single-rooted single-canal extracted human premolar teeth were used. tooth crowns were separated from the roots at the cementoenamel junction (cej). roots were buccolingually sectioned into mesial and distal halves. specimens were randomly divided into 5 ...
