Maxillary transverse discrepancy usually requires expansion of the palate by a combination of orthopedic and orthodontic tooth movements. Three expansion treatment modalities are used today: rapid maxillary expansion, slow maxillary expansion and surgically assisted maxillary expansion.This article aims to review the maxillary expansion by all the three modalities and a brief on commonly used appliances.
Analysis of prevalence of various types of malocclusion is an important aspect of today's evidence-based dentistry. Orthodontic indices are a tool in the hands of an epidemiologist to analyze the prevalence and severity of various kinds of malocclusion. The aim of this article is to look into the various qualitative and quantitative methods of grading and assessing malocclusion and their evolution over the years along with their advantages and limitations have also been analyzed. The article also compares the commonly used indices—DAI and IOTN.

Cross bite is a condition where one or more teeth may be abnormally malposed buccally or lingually or labially with reference to the opposing tooth or teeth. Cross bite correction is highly recommended as this kind of malocclusion do not diminish with age. Uncorrected cross bite may lead to abnormal wear of lower anteriors and cuspal interference, mandibular shift resulting in mandibular asymmetry and temporomandibular joint dysfunction syndrome. There are several methods for treating this type of malocclusion. In this article, segmental orthodontics has been highlighted by using 2 × 4 appliance therapy and lingual button with cross elastics. This appliance offers many advantages as it provides complete control of anterior tooth position, is extremely well tolerated, requires no adjustment by the patient and allows accurate and rapid positioning of teeth.
Introduction: This article illustrates a new treatment approach and evaluates the effect of use of fluoridated toothpaste on the remineralization of white spot lesions (WSLs) diagnosed at debonding.Materials and methods: Thirty-one orthodontic patients (mean age: 19.6 years), with a minimum of four WSLs on the buccal surfaces of the maxillary and mandibular incisors, canines, premolars and first molars after orthodontic therapy, were enrolled in a double-blind, randomized, longitudinal trial lasting 8 weeks. The subjects were divided into two groups using fluoridated toothpaste (test group, n = 31) and nonfluoridated toothpaste (control group, n = 31). A custom-made mouth tray, covering the maxillary dentition, was used while brushing with the fluoridated toothpaste three times per day. Maxillary dentition acted as control and mandibular as the test. The WSLs were scored by using the International Caries Detection and Assessment System (ICDAS II) index, at baseline and 8 weeks after debonding.Results: The ICDAS II index of the WSLs decreased in the test group in the mandibular dentition but not on the maxillary dentition during the 8-week trial (p < 0.0001). There was also a slight improvement in the control group (not significant).Conclusion: The frequent use of fluoridated toothpaste had a remineralizing effect on WSLs.How to cite this article: Agarwal A, Pandey H, Pandey L, Choudhary G.
