Newer Technique of Extra-Coronal Bleaching with Sodium Perborate on Non-Pitted Fluorosis Stains in Permanent Anterior Teeth.

Variety of treatment approaches have been proposed for esthetic management of dental fluorosis. Microabrasion, bleaching using hydrogen peroxide, and etch bleach seal are commonly used methods. Bleaching using sodium perborate has been used for intracoronal bleaching. Till now, no study has used sodium perborate for extracoronal bleaching of discolored stained teeth. OBJECTIVES: To evaluate the esthetic improvement of non-pitted fluorosis stains using sodium perborate and compare with etch bleach seal, microabrasion and in-office bleaching with 30% H2O2 on visual assessment scale VAS (primary objective) and to assess any untoward effects including staining, sensitivity, gingival problems within the course of study (secondary objectives). STUDY DESIGN: A randomized control trial with 6 months follow up. Methodology- Twenty children aged 8 to 12 years with non-pitted fluorosis in upper anterior teeth were divided into 4 groups with 5 patients in each group. RESULTS AND DISCUSSION: All of the techniques showed improvement in esthetics with VAS. However, microabrasion and bleaching using sodium perborate had significantly better results than other 2 techniques. CONCLUSION: Sodium perborate showed excellent results in extracoronal bleaching of fluorosed teeth. However a randomized study with large sample size is required to draw a definitive conclusion regarding superiority of one technique over others.

A Rare Case of non Syndromic Congenital Idiopathic Gingival Fibromatosis: Electrosurgical Management.

Idiopathic gingival fibromatosis (IGF) is a rare, genetically heterogeneous condition that is usually a part of syndrome or, rarely, an isolated disorder. It is characterized by a slowly progressive, non hemorrhagic, fibrous enlargement of keratinized gingiva which usually begins at the time of eruption of permanent dentition, however very few cases involving the primary teeth have been described in literature. Congenital gingival fibromatosis is very rare condition in which the gingival tissues become thickened and erupting teeth remain submerged beneath hyperplastic tissue masses. This case report discusses the rare case of congenital non syndromic idiopathic gingival fibromatosis in a two year old boy who reported with absence of teeth and incompetent lips. Gingivectomy was done using modified microdissection electrocautery needle to remove the excess gingival tissues. Excised tissue has been examined histologically. The patient was followed up for a period of one year and no recurrence was observed.

Extrafollicular Adenomatoid Odontogenic Tumor in the Maxillary Incisor Region Disguised as Gingival Swelling.

Adenomatoid Odontogenic Tumor (AOT) is a benign, non-invasive tumor with slow but progressive growth, mainly affecting younger patients, predominantly females. It is more often located in maxilla, involving an unerupted or erupted tooth, mostly canine. There are three variants, namely follicular, extra-follicular and peripheral. Permanent cuspids account for 60% of all follicular and 89% of all extra-follicular AOT. This article discusses a unique case of extra-follicular AOT in 9 year old male patient associated with partially erupted maxillary central incisor.

Assessment of indoor radon, thoron concentrations, and their relationship with seasonal variation and geology of Udhampur district, Jammu & Kashmir, India.

Background The inhalation doses resulting from the exposure to radon, thoron, and their progeny are important quantities in estimating the radiation risk for epidemiological studies as the average global annual effective dose due to radon and its progeny is 1.3 mSv as compared to that of 2.4 mSv due to all other natural sources of ionizing radiation. Objectives The annual inhalation dose has been assessed with an aim of investigating the health risk to the inhabitants of the studied region. Methods Time integrated deposition based 222Rn/220Rn sensors have been used to measure concentrations in 146 dwellings of Udhampur district, Jammu and Kashmir. An active smart RnDuo monitor has also been used for comparison purposes. Results The range of indoor radon/thoron concentrations is found to vary from 11 to 58 Bqm-3 with an average value of 29 ± 9 Bqm-3 and from 25 to 185 Bqm-3 with an average value of 83 ± 32 Bqm-3, respectively. About 10.7% dwellings have higher values than world average of 40 Bqm-3 prescribed by UNSCEAR. The relationship of indoor radon and thoron levels with different seasons, ventilation conditions, and different geological formations have been discussed. Conclusions The observed values of concentrations and average annual effective dose due to radon, thoron, and its progeny in the study area have been found to be below the recommended level of ICRP. The observed concentrations of 222Rn and 220Rn measured with active and passive techniques are found to be in good agreement.
