BACKGROUND: Manganese (Mn) is an essential metal that can become neurotoxic at elevated levels with negative consequences on neurodevelopment. We have evaluated the influence of single nucleotide polymorphisms (SNPs) in Mn transporter genes SLC30A10 and SLC39A8 on Mn concentrations in dentine, a validated biomarker that reflects Mn tissue concentrations early in life. METHODS: The study included 195 children with variable environmental Mn exposure. Mn concentrations in dentine representing fetal, early postnatal and early childhood developmental periods were measured using laser ablation-inductively coupled plasma mass spectrometry...

This study attempted to identify appropriate materials for restoration of enamel defects in the primary dentition, which were classified by severity and region with the modified developmental defects of enamel index. To identify the most appropriate materials, we used restorative materials to protect teeth and evaluated clinical outcomes of restoration. Three materials were used for restoration or repair after dislodgement of restorations. Our findings in this case suggest that, because of its durability and esthetic advantages, adhesive resin is beneficial for patients with enamel defects, particularly for restorations of less than two-thirds of the extent of the defect...

Patients may face functional, aesthetic, and social distress because of the palatal defects. Prosthetic rehabilitation of maxillectomy or developmental defect can be challenging for prosthodontists. Prognosis of the prosthetic appliances can be affected not only by patients' own ability to adapt to the prosthesis but also by the factors like the remaining teeth, bony structure, and existing mucosa. Maxillary defects are usually developed by surgical intercession of the benign or malignant conditions and trauma cases...

INTRODUCTION: Lifelong preservation of tooth in a healthy state is the ultimate goal of dentistry. Premature loss of primary teeth is common due to caries, dental trauma or other causes. As the primary teeth are the best space maintainers, teeth with infected pulps should be retained until exfoliation, whenever possible. AIM: The purpose of this in vivo study was to evaluate and compare the efficacy of different obturating methods used in primary teeth. MATERIALS AND METHODS: Forty one patients aged four to nine years with a total of 60 teeth were selected...

Fusions of teeth and talon cusp are two rare developmental dental anomalies, affecting both primary and permanent dentitions. Both the anomalies are mostly reported as isolated finding and are rarely associated with other dental anomalies. Talon cusp is more common in maxillary anterior teeth in permanent dentition and fusion is commonly reported in mandibular teeth in primary dentition. The concomitant occurrence of talon cusp and fusion is rare and its occurrence in fused mandibular permanent teeth is also rare...

INTRODUCTION: Formocresol has been a popular pulpotomy medicament for many years. It is considered the "gold standard" in pediatric dentistry. However, concerns have been raised over its use in children. It has been reported that formocresol has toxic and mutagenic effects in cell culture, dental crypts, and precancerous epithelial cells. Therefore, additional biocompatible treatment alternatives are required to replace formocresol pulpotomy. AIMS: This study compared the clinical and radiographic success rates of ferric sulfate (FS) and bioactive tricalcium silicate cement (Biodentine, Septodont) as pulpotomy agents in primary molar teeth over a period of 9 months...

BACKGROUND: Early childhood caries discloses a distinct clinical pattern, and the teeth most often involved are the maxillary central incisors, lateral incisors, and the maxillary and man-dibular first molars. The maxillary incisors are most severely affected, with deep carious lesions usually involving the pulp. Teeth that have been endodontically treated often have little coronal tooth tissue remaining and as such require a post to retain the core and restoration .This study evaluated and compared the efficacy of EverStick glass fiber-reinforced composite post with ParaPost Taper Lux in primary maxillary anterior teeth...
