REVIEW ARTICLE
Sterilization and orthodontics: A literature review
Jeevan M Khatri, Manjusha M Jadhav, Gaurav H Tated
October-December 2017, 8(4):141-146
DOI:10.4103/ijor.ijor_36_17  
Sterilization is a process by which an article, surface or medium is freed of all microorganisms either in vegetative or spore state. On a daily basis, the practicing dentist and his personal are at risk of being exposed to wide patients with blood borne diseases such as HIV/AIDS, hepatitis B, C, and airborne diseases such as tuberculosis. Infection can be directly transmitted by oral fluids, blood, contaminated instruments and surfaces, or through the respiratory system. Control of infection that spreads through various instruments and armamentarium used in the field of orthodontics and dentistry in general is of utmost importance as a preventive measure for cross infection. Considering the fact that the rate at which newer strains evolve with time and older strains develop resistance, it has become a constant challenge through time and in the years to come. This article tells about various methods of sterilization by focusing on the guidelines for an effective and efficient orthodontic practice.

A comparative evaluation of bite opening by temporary anchorage devices and Connecticut intrusion arch: An in vivo study
Neha Gupta, Tulika Tripathi, Priyank Rai, Anup Kanase, Neha
October-December 2017, 8(4):129-135
DOI:10.4103/ijor.ijor_28_17  
Introduction: Deep bite correction in patients with convex profile and increased maxillary incisor visibility, and normal or increased vertical dimension necessitates the intrusion of maxillary incisors. Intrusion arches or miniscrews are commonly used for this purpose. The current study compares one of the prefabricated intrusion arches, the Connecticut intrusion arch (CIA), and the temporary anchorage devices (TADs) in their effectiveness for orthodontic intrusion. Materials and Methods: The present prospective study was done on 24 patients in the age group of 15–25 years undergoing fixed orthodontic treatment. In Group I, TADs were placed for intrusion while, in Group II, CIA was placed. Anchorage was reinforced in Group II using transpalatal arch. A paired t-test or a Wilcoxon signed-rank test was performed for the assessment of treatment changes within the groups, and an independent t-test or a Mann–Whitney U-test evaluated change between the groups. Results: Both TADs and CIA can bring about significant amount of true incisor intrusion with resultant decrease in incisor visibility. However, in the TAD group, in addition to intrusion, the incisors also proclined by 0.67 mm, but in CIA group, incisors retracted by 0.33 mm. There were nonsignificant mesial drift and significant extrusive movement of the maxillary first molars in the CIA group. The rate and amount of intrusion was greater in the TAD group. Conclusions: Both TADs and CIA can be effectively used for incisor intrusion which was, however, faster and greater in TAD group. Both the methods bring about associated unwanted tooth movements as well.

Camouflage treatment of Angle's Class III malocclusion in a young adult
Zeeshan Iqbal Bhat
October-December 2017, 8(4):154-158
DOI:10.4103/ijor.ijor_42_16  
A case report is presented of a class III malocclusion with a class III skeletal pattern with prognathic maxilla and mandible in relation to cranium and prognathic mandible in relation to maxilla. The smile was unesthetic as there was a generalised spacing and the maxillary teeth were retroclined and mandibular proclined with more exposure of mandibular teeth. Camouflage treatment was carried out by closure of all the spaces and correcting anterior crossbite.

Tempo blocks
Khushbu Dinesh Agrawal, Suresh K Kangane, Anand Ambekar
October-December 2017, 8(4):161-163
DOI:10.4103/ijor.ijor_31_17  
Bite opening is often required to achieve clearance for correction of certain malocclusions such as crossbites or deep overbites. The present article introduces “tempo blocks” which are easy to fabricate and use and can be used along with the fixed orthodontic appliance in place.

Phase I correction of skeletal Class III malocclusion with a modified tandem appliance
J Mohamed Iqbal, MD Sofitha
October-December 2017, 8(4):150-153
DOI:10.4103/ijor.ijor_29_17  
Skeletal Class III malocclusion is considered a syndrome with presentation differing in phenotype as well as genotype and inheritance. Class III malocclusion with retrognathic maxilla has a good prognosis for early treatment and face mask therapy is the traditional appliance of choice. However, patient compliance is a major deterrent. Modified tandem appliance is an effective alternative to face mask in bringing about the requisite changes along with excellent patient compliance, attributed to its minimalist design.

Reactivation of NiTi open coil spring using crimpable hook: A clinical pearl
Surendra Kumar Sewda, Akshay Madhukar Waingankar, Mohit Sharma, MP Prasanna Kumar, Amit Jain
October-December 2017, 8(4):159-160
DOI:10.4103/ijor.ijor_25_17  
Ni-Ti open coil springs are often used to create space for alignment of malposed teeth. Predetermining the length of open coil spring required to open up the exact amount of space is rather difficult, and occasionally, the length of the open coil spring falls short to open up the entire space required. This article highlights the chairside intraoral method of reactivation of NiTi open coil spring with the use of crimpable hook without removing the base archwire.

The applicability of Bolton's tooth size ratios for population-specific malocclusion
Zafar Iqbal Javed Iqbal Sayed, Anish Dnyneshwar Doke
October-December 2017, 8(4):136-140
DOI:10.4103/ijor.ijor_35_17  
Aims: This study aims to evaluate the Bolton ratio in Beed population in Maharashtra with different malocclusion. Materials and Methods: Fifty study casts were taken from the patients undergoing orthodontic treatment, and individuals were divided into three groups: Group I (Angle's Class I, n = 25), Group II (Angle's Class II, n = 25), and Group III (mean of Group I and Group II). Statistical Analysis Used: ANOVA and Tukey's test. Results: A mean total Bolton ratio of 93.05 ± 5.87 and a mean anterior Bolton ratio of 81.08 ± 5.93 were found for the sample; significantly, higher mean anterior tooth ratios were found for Group I (Angle's Class I) patients (P < 0.03). Conclusions: Mean anterior tooth size discrepancy for Angle Class I individuals was significantly greater compared to Bolton's mean anterior ratio.
