Nanosilver Fluoride-A Paradigm Shift for Arrest in Dental Caries in Primary Teeth of Schoolchildren: A Randomized Controlled Clinical Trial.

BACKGROUND: Due to limited financial resources, poor access to basic oral care, and the high cost of restorative treatment, children of low-income nations have their general health, social well-being, and education opportunities affected by untreated dental caries. Arresting caries treatment (ACT) has been proposed to manage untreated dental caries in children of disadvantaged communities. AIMS AND OBJECTIVES: The purpose of the present controlled clinical trial is to investigate the effectiveness of a new anticaries agent, nanosilver fluoride (NSF), preventing and arresting caries in children. MATERIALS AND METHODS: A total of 100 deciduous molars both maxillary and mandibular are randomly selected from 60 children of 4-9 years of age group, which were randomly divided into NSF experimental group and saline control group. Teeth were clinically diagnosed and treated by one masked examiner and followed up at 7 days, 5 months and 12 months by another calibrated examiner who was blinded to the type of treatment. The criteria of the ICDAS II were followed to determine the activity of lesion and the diagnosis of caries. The Pearson's Chi-square test was used to compare the groups during different follow-up examinations. RESULTS: Seventy-eight percent of decayed teeth showed hard arrested dentine at 7 days; after 5-month analysis in the NSF group, 72.91% of the teeth showed arrested caries; and in the control group, only 34% of teeth showed arrest of caries. At 12-month analysis in the NSF group, 65.21% of teeth showed arrested cavities, and in the control group, 28.88% of teeth showed arrest of caries. CONCLUSION: The present study proves that NSF is an anticaries agent and presents a noninvasive option for caries arrest and treatment when applied directly to dentin caries lesions.

Clinical, Radiological, and Histological Assessment of Magnetic Nanoparticles as Pulpotomy Medicament in Primary Molars.

AIM AND OBJECTIVES: Aim of the study was to evaluate the success of magnetic nanoparticles (MNPs) as pulpotomy medicament by clinical, radiologic, and histological assessment in primary molars. MATERIALS AND METHODS: The sample included 30 primary molars from 25 children aged between 3 and 9 years requiring pulpotomy treatment. Pulpotomy was carried out with MNPs. The teeth were evaluated after a period of 3, 6, and 12 months clinically and with the aid of radiographs. After 1 year, 10 teeth were extracted for histological evaluation under field emission scanning electron microscope (FE-SEM; ZEISS, Model No. Supra 55vp). RESULTS: Of the samples, 98% showed clinical success rate with absence of pain, swelling, mobility, and abscess formation. After 3 months, 98% radiological success with absence of periodontal ligament widening, root resorption, and inter-radicular radiolucency was noted. Histological examination carried out under FE-SEM revealed a zone of odontoblastic proliferation at the interface between MNPs and odontoblastic layer of pulp and viable pulpal cells from the canal orifice till apical foramen. CONCLUSION: Magnetic nanoparticles can be recommended as an effective pulpotomy medicament with hard tissue barrier formation and preservation of vitality of remaining radicular pulp.How to cite this article: Konyala HR, Mareddy AR, Puppala N, Reddy NV, Mallela MK, Susheela KP.

Central Odontogenic Fibroma of the Mandible.

The central odontogenic fibroma (COF) is a benign odontogenic tumor of mesenchymal tissue such as the periodontal ligament, dental papilla or dental follicle. It is an extremely rare tumor, accounting less than five percent of all odontogenic tumors. In this report, we describe the case of an eight year old girl who presented with a painless swelling of the left mandible. Radiographic evaluation revealed a well-defined unilocular radiolucency extending from the distal aspect of the displaced mandibular left premolar to the ascending ramus of the mandible. Histopathological examination confirmed the diagnosis of COF of the simple type. Surgical excision of the lesion was done and no recurrence was noted thereafter.

Cavernous hemangioma of tongue: management of two cases.

Hemangiomas are benign tumours of infancy and childhood, most commonly located in the head and neck region and occur more frequently in the lips, tongue and palate. The treatment depends upon lesion location, size and evolution stage and the patient's age. This paper describes the management of cavernous hemangioma in a 2 -year -old child and 14 -year -old child using different approaches.
