ABSTRACT
In orthodontics, the stability of the final occlusion is as important as the correction achieved. Since the beginning of the century, fixed retainers have been recommended after correction of rotated or tipped incisors and/or for maintenance of increased intercanine width. However, bonding a lingual retainer is still challenging as it requires long working time and has a risk of contamination from saliva and moisture which can cause bonding failure. So, the need for a device which would hold the lingual retainer wire was felt. So, a device was developed to hold wire with an ease, while bonding the lingual retainer.
Keywords: Orthodontic treatment, Fixed retainer, Lingual retainer, Retention, Device.

ABSTRACT
As compared to other ethnic groups relatively few measurements on tooth size have been made on Indian population. Hence, a study was carried out in Department of Orthodontics, Saveetha Dental College, Chennai, to discern the average clinical crown dimensions for cervicoincisal heights (CIH) and mesiodistal widths (MDW), permanent dentition for the local population, to find out the amount of variation in CIH and MDW between males and females, between right and left sides and tooth showing maximum and minimum variation. The study was carried out on study models of 100 patients who visited the OPD of the above college, and measurements were done using Digital Vernier calipers. The results showed that CIH and MDW are generally larger for male teeth compared to female and left side 2nd molars showed clinically significant variation in CIH. The study also showed that in both sexes and arches maximum variation in CIH was for central incisor and minimum for 2nd molar. In MDW, maximum variation is for 2nd molar and minimum for 2nd premolars in both arches.
The study is helpful in establishling Bolton's standards for assessing tooth size discrepancy and also in application of mixed dentition model analysis and bracket positioning chart for preadjusted edgewise appliance for the local population.
Keywords: Cervicoincisal heights (CIH), Mesiodistal widths (MDW), Digital Vernier calipers, Males and females.

ABSTRACT
Introduction: The success behind orthodontic diagnosis and treatment planning lies in appropriate evaluation of the patient’s soft tissue profile appearance.
Aims and objectives: The aim of this study was to obtain average angular photogrammetric measurements of the soft tissue facial profile of north Indian males and females.
Materials and methods: A sample of 150 north Indian individuals (78 males and 72 females) between 18 and 25 years of age was obtained with a class I dental relationship. The photographic set-up consisted of a tripod that held a digital SLR camera. The photographic records of the subjects were taken in natural head posture. The obtained records were digitized and analyzed using the Nemoceph NX software program for Windows. Ten measurements were digitally analyzed on each photograph. For statistical evaluation Student’s t-test was performed and the reliability of the method was analyzed. The results were compared with established soft tissue profile photogrammetric norms.
Results: The facial convexity, maxillary lip contour, nasal tip, nasolabial, nasomental and nasofacial angles showed statistically insignificant gender differences. The nasofrontal, total facial convexity, cervicomental and mandibular lip contour angle demonstrated significant gender differences.
Conclusion: The average values obtained in our study for the young adult north Indian population should be considered in the runup to their diagnosis and treatment planning.
Keywords: Photogrammetry, Angular facial measurements, North Indian adults.

ABSTRACT
Introduction: The purpose of this study was to evaluate and compare the shear bond strength between the bracket and acid etched enamel, enamel treated with self-etch primer and laser irradiated enamel and to analyze the interface of the enamel bracket bond.
Materials and methods: Around 60 noncarious human premolars were divided randomly into three groups of 20 each and etched using 37% phosphoric acid, self-etch primer and Er:YAG laser. Stainless steel brackets were then bonded using Transbond XT following which all the samples were stored in distilled water at room temperature for 24 hours. Shear bond strength was tested using a chisel edge, mounted on the crosshead of Universal Testing Machine. After debonding, the teeth were examined under 10× magnification with a stereomicroscope and ARI score determined. Shear bond strengths of the three groups were then compared using ANOVA test (multiple comparisons, Tukey’s correction). Comparison of the ARI scores was done using Chi-square test.
Result: The acid etched group yielded the highest mean debonding force (13.34 Mpa) followed by self-etch group (12.15 Mpa) and laser etch group (12.10 Mpa). No significant difference was found between the three groups. On comparison of the ARI scores, it was found that the adhesive left on the enamel surface after debonding was significantly higher in the acid etched group than the self-etch group (p = 0.009). There was no significant difference in the ARI scores between the other two groups.
Conclusion: These results indicate that the shear bond strength of all the three groups was clinically acceptable with no significant difference between them but more adhesive was left on enamel treated with acid and laser as compared to self-etch primer treated enamel.
Keywords: Bond strength, Orthodontic brackets, Laser etching, Self etching primer, ARI score, Caries prevention.

ABSTRACT
A study of the properties of NiTi wires used by patients and then sterilized by practical methods can give us the answer to our million dollar questions-can we recycle NiTi wires without affecting the quality of orthodontic treatment? 30 wire samples of 0.016 inch nickel-titanium alloy (Nitanium) (Ortho Organizers, Inc, CA) were collected from patients after using them for specified time period. These samples were cleaned with a solution of 70% isopropyl alcohol and then sterilized by (1) Autoclave and (2) Cold sterilization. Samples from each group were subjected to mechanical testing procedures: (1) Three point bending test (2) Uniaxial cyclic tensile test (3) Uniaxial tensile test till failure. A comparison of the mechanical properties was done of new and recycled wires.
Keywords: NiTi wires, Recycling, Mechanical properties.

ABSTRACT
The orthodontist role in a cleft palate craniofacial team is undebatable. For satisfactory results, close coordination among team members is mandatory. This interactive, evidence-based and patient-centered care should provide the basis for a rational approach to diagnosis and treatment planning. The ultimate goal is to have fully rehabilitated patient who is satisfied with the treatment outcomes in terms of speech, occlusion, facial and dental esthetics and function.
This case report describes management of an adult patient with a traumatically repaired cleft. The maxilla was deficient in all three planes and the mandible appeared protrusive. The patient's speech had nasalance and articulation problems. The patient was informed about the possibility of speech deterioration post-surgery and was explained about the options available. After appropriate presurgical orthodontics, maxilla was surgically expanded and was also advanced by 5 mm. After surgery, speech was more intelligible because of improved articulation. It was possible to get optimum esthetic and functional result due to coordinated team approach.
Keywords: Adult, Cleft, Trauma.
