Changes in the oral health-related quality of life 24 h following insertion of fixed orthodontic appliances
Noorhanizar Mansor, Roslan Saub, Siti Adibah Othman
J Orthodont Sci
2012, 1:98 (11 January 2013)
DOI
:10.4103/2278-0203.105880
PMID
:24987635
Objectives:
The objective of this study was to assess changes in the oral health-related quality of life (OHRQoL) among patients wearing fixed orthodontic appliances 24 h after insertion.
Materials and Methods:
Sixty patients aged between 14 and 24 years (29 males and 31 females; mean age, 17.8 years; SD 3.1 years) were recruited from the Postgraduate Clinic, Department of Children's Dentistry and Orthodontics, Faculty of Dentistry, University of Malaya. The oral health-related quality of life (OHRQoL) was measured before treatment and 24 h after insertion of the orthodontic appliance. The instrument used to measure OHRQoL was a modified self-administered short version of Malaysian Oral Health Impact Profile (OHIP-16[M]) questionnaire. The higher the score, the poorer is the OHRQoL.
Results:
Overall score of OHRQoL increased significantly 24 h after insertion (mean 43.5±10.9) as compared to before insertion (mean 34.1±9.2) (
P
<0.001). Significant changes were found for the following items: Difficulties in chewing, bad breath, difficulties in pronunciation, discomfort in eating, ulcer, pain, avoidances of eating certain foods, difficulties in cleaning, embarrassment, avoid smiling, disturbed sleep, concentration affected, difficulty carrying out daily activities, and lack of self-confidence (
P
<0.05). Significant changes were also found in the mean difference of OHRQoL for gender (
P
<0.001).
Conclusion:
OHRQoL was found to deteriorate 24 h after insertion of fixed orthodontic appliances in almost all domains, with significant changes in gender. This information can be used as "informed consent," which might increase patient's compliance as they are aware of what to expect from initial orthodontic treatment.

Original Article:
Soft-tissue cephalometric norms in a north Indian ethnic population
Avesh Sachan, Adit Srivastav, TP Chaturvedi
J Orthodont Sci
2012, 1:92 (11 January 2013)
DOI
:10.4103/2278-0203.105877
PMID
:24987634
Background:
Soft tissues play the primary role of physical appearance and facial esthetics. This study aimed to establish soft-tissue cephalometric standards in North Indian adults, which can be used in diagnosis, treatment planning, and stability of orthodontic outcome and orthognathic patients.
Materials and Methods:
A group of 60 individuals (30 males and 30 females) with normal occlusion and proportional facial profile were chosen. For the entire chosen sample, lateral cephalograms were obtained. Standard values of 11 soft-tissue measurements were determined.
Results:
Soft-tissue measurements showed that men had greater soft-tissue facial angle (92.10°) than women (89.92°). Also, they had more nose prominence (18.10 mm) than women (16.44 mm). Skeletal profile convexity (A to N-pog) of men (0.40 mm) was less than women (1.76 mm). Basic upper lip thickness was higher in men (16.60 mm) compared to women (14.24 mm), while H-angle was higher in women (16.68°) as compared to men (14.30°). In the lower face area, inferior sulcus to the H line distance was more in men (7.30 mm) than women (4.80 mm). Men had greater soft-tissue chin thickness (14.10 mm) than women (12.84 mm).
Conclusion:
The differences in soft-tissue cephalometric norms between men and women of North Indian faces were established, so the orthodontist or surgeon must individualize treatment planning, using local norms as the reference.

Original Article:
Comparison of Wits appraisal among different ethnic groups
Khalid H Zawawi
J Orthodont Sci
2012, 1:88 (11 January 2013)
DOI
:10.4103/2278-0203.105874
PMID
:24987633
Objectives:
The Wits values for various ethnic groups are different and the applicability of the norms described in these analyses to different populations is difficult. The objectives of this study were to establish the normal values of Wits appraisal in a sample from the western region of Saudi Arabia and to evaluate the existence of gender dimorphism. Also, to compare the results with previously published Wits values.
Materials and
Methods:
A total of 66 lateral cephalometric digital radiographs of Saudi patients from the western region (25 males and 41 females, mean age 19.32±8.16 years and 20.88±8.77 years, respectively). All subjects had angle class-I occlusion, well-balanced faces, all premolars had erupted and in occlusion, and no history of orthodontic treatment. Tracing was performed using the VistadentOC
®
software.
Results:
Wits mean values were greater in males (−0.73±2.48) than females (1.79±2.06), with significant gender difference (
P
<0.001). Comparisons with previously published showed that there is a significant differences between ethnic groups, especially in females' data.
Conclusion:
Wits appraisal appears to be gender-specific and ethnicity-specific for female values.

Review Article:
Allergy and orthodontics
Sunitha Chakravarthi, Sridevi Padmanabhan, Arun B Chitharanjan
J Orthodont Sci
2012, 1:83 (11 January 2013)
DOI
:10.4103/2278-0203.105871
PMID
:24987632
The aim of this paper is to review the current literature on allergy in orthodontics and to identify the predisposing factors and the implications of the allergic reaction in the management of patients during orthodontic treatment. A computerized literature search was conducted in PubMed for articles published on allergy in relation to orthodontics. The MeSH term used was allergy and orthodontics. Allergic response to alloys in orthodontics, particularly nickel, has been extensively studied and several case reports of nickel-induced contact dermatitis have been documented. Current evidence suggests that the most common allergic reaction reported in orthodontics is related to nickel in orthodontic appliances and allergic response is more common in women due to a previous sensitizing exposure from nickel in jewellery. Studies have implicated allergy in the etiology of hypo-dontia. It has also been considered as a high-risk factor for development of extensive root resorption during the course of orthodontic treatment. This review discusses the relationship and implications of allergy in orthodontics.
