To assess the acceleration of tooth movement in canine retraction and to assess the interleukin 1β level in Gingival Crevicular Fluid. 0.022 slot MBT brackets, 0.018 inch stainless steel arch wire, Low level laser (Gallium-Aluminium-Arsenide Laser), ELISA kit, Micro-capillary tube, Digital Vernier calliper, Dontrics gauge, NiTi closed coil springs Open labelled split mouth, non-experimental interventional institutional based study. By coin toss method, each of the participant’s mouth was randomly assigned either to the laser therapy (group 1) and 40 reference sites (group 2). On the experimental site orthodontic treatment with fixed appliance, a combination with low level laser therapy (Gallium-Aluminium-Arsenide laser) to the canine on the days 3,7,14 and then every 15 days for 2 months was initiated. Then 5µL of Gingival Crevicular Fluid (GCF) was collected to analyse the interleukin 1β levels using the ELIZA kit. The measurements were made with the help of a digital Vernier calliper. The laser group showed a significant greater reduction in the canine to molar distance than the site treated with conventional technique. The interleukin 1 β levels raised significantly for the site treated with laser as compared to the other. We observed that: Increased inflammatory response in the form of raised interleukin levels and Faster distalization of the canine when adjunct with low level soft tissue laser. The entire data was statistically analyzed using Statistical Package for Social Sciences (SPSS version 21.0, IBM Corporation, USA) for MS Windows. In Statistics, unpaired t-test is a used to compare equality of two population means and F-test is used to compare the equality of two population variance using that the samples were drawn from different populations. There was a clinically appreciable amount of retraction seen resulting in faster space closure between the canine and the first permanent molar in the group that had low level laser than the other group that was treated by the conventional therapy. We also observed a considerable rise in the interleukin 1 β levels in the laser group.

Orthodontic treatment commonly requires posted archwires for en-masse retraction, for attaching headgear and elastics. Prefabricated brass-posted archwires are popular, the main disadvantages being extended inventory and cost. Considering all these challenges, this new V-Jig has been introduced. The innovation of this jig allows freehand operation, with more precision of placement of posts on the archwire and reduces chances of loss of original wire properties. Soldering technique with jig is convenient and easy. It is a chairside apparatus to make posted archwire and other appliances with ease.

Objective: To estimate the correlation and variant heritability values of craniofacial variables between parents and their offspring. Materials and Methods: The sample comprised 20 Indian families; each family consisted of father, mother, son, and daughter. Lateral cephalometric radiographs and facial photographs were taken for each family member.Fifty -three angular, linear, and proportional cephalometric variables were measured and photographic analysis was done. Interfamilial correlations and heritability (h2) values were estimated among father-son, father-daughter,mother-son, and mother-daughter pairings. Results: The most similar angular measurements between parents and offspring were as follows:SNA0,SNB0 ,ANB0 ,FMA0, MP-FH0 , LI-NB0, Op-FH0 ,UI-NA0 , OP-SN0, LI-NB0 and The most similar linear measurements were as follows: Co-Pt.A,Co-Gn, N- ANS, , UI-A, Me-Me’,LI-A.Pog, Mx 1 exposure. Both the correlation coefficients and the heritable values were stronger in the father-offspring than the mother-offspring pairings. Conclusions: The overall correlation and h2 mean values for the three types of measurements showed stronger values in the father-offspring than the mother-offspring groups, with the father –son pairings more significant than the father-daughter groups. KEY WORDS: Cephalometrics; Heritability; Facial photographs; Craniofacial features; Offspring.

Objectives: (1) To evaluate the influence of the amount of gingival display on smile esthetics and to compare the esthetic perception of six levels of gingival exposure (−3, −1, 0, +1, +3, +5 mm) between orthodontists, maxillofacial surgeons, dental students, and laypersons. (2) To evaluate the most acceptable level of gingival display during smile. Materials and Methods: Twelve adult females (20–30 years of age) were included in the study. A frontal intraoral and a frontal extraoral smile photograph were obtained from each of them. A total of six images were created with different levels of gingival display. Each image was evaluated for its attractiveness by 60 observers. Results: Analysis of variance with post hoc Tukey's correction was the statistics used. The average ratings for gingival display of −3 and +3 mm did not differ across all the observers. Dental students and laypersons gave significantly higher ratings for −1 mm and 0 mm and significantly lesser ratings for +1 mm and +5 mm, when compared to the orthodontists and maxillofacial surgeons. Conclusions: The smile with 0 mm gingival display was considered to be the most esthetic by all observers. Smile with +1 mm gingival display was the second most attractive smile according to the orthodontists and maxillofacial surgeons while for the dental students and laypersons, it was the smile with −1 mm gingival display.

Background: Friction plays a major role during tooth movement as it takes up to 60% of the applied force, hence reducing the force available for tooth movement. Coating the surface of orthodontic wires by various techniques is being developed to improve their mechanical and biological properties. Objectives: To evaluate the characteristics of nano particle coated and uncoated stainless steel, nickel-titanium, and beta-titanium wires for (1) coating stability, (2) surface characteristics and (3) biocompatibility after 21 days of exposure to artificial saliva. Methods: Six types of wires were tested for coating stability, surface characteristics before and after exposure to artificial saliva using scanning electron microscope and the artificial saliva was tested for leaching of ions by inductively coupled plasma optical emission spectrometer. Results: Coating thickness was reduced in each group after exposure to artificial saliva which was statistically significant. Significant changes in surface morphology such as delamination and irregularity of the coating was noted. Coated NiTi wires showed lesser leaching of ions when compared with uncoated NiTi wires but the difference was not statistically significant. Conclusions: Coating delamination and irregularities were seen in many areas. The highest concentration of ions leached among all the groups were of iron, followed by silica.

Objective: To determine if text messaging reminders regarding intra oral elastic wear have any influence on the level of compliance in an orthodontic population. Materials & Methods: Eighty orthodontic patients were considered out of which 40 patients (20 Males & 20 Females) were assigned to a text message group (Study Group) & 40 patients (20 Males & 20 Females) were assigned to a Non-text message group (Control group), who did not receive a reminder text message. Message was sent once daily for a period of one month. The participants were given a fixed number of elastics (60 per patient) at the start of the study and were asked to collect used elastics for the period of one month and counts of these were used to assess compliance. Results: Compliance with elastic wear had significant difference among patients. Female patients proved to be more compliant compared to males in both the groups. The study group returned more number of used elastics than the control group, suggesting increased compliance. Conclusion: A text message reminder system explaining the importance of wearing Intra-oral elastics sent to patients once daily is an effective way to improve compliance in orthodontic patients.

Objective: To determine if text messaging reminders regarding oral hygiene have any influence on the level of compliance with an orthodontic population. Material & Method: 50 orthodontic patients were considered out of which 25 patients’ parents were assigned text message group & 25 parents of patients were assigned in the non-text message group, which did not receive a reminder text message (control group). Message was sent once a week for 4 months. Oral hygiene compliance was measured using, plaque index (PI), and visual examination of white spot lesion (WSL). 1st appointment after two month (T0); 2nd appointment after three months (T1); 3rd appointments after four months (T2);4th appointment after five months (T3). Results: The average plaque index is significantly higher in Control group compared to Text-messaging group at 3 and 4 months post-messaging follow-ups while incidence of white spot lesions is significantly higher in control group compared to the text-messaging group at 3 months and 4 months post-messaging follow-ups. Conclusion: A text message reminder system explaining the importance of oral hygiene sent to patients once weekly is an effective way to improve oral hygiene compliance in orthodontic patients.

Background In contemporary dental care, an increasing number of adult patients are now seeking orthodontic treatment with the primary motive of improvement in appearance and achievement of esthetic smile. Proper recognition of the dental and facial defects at the outset of treatment is the most important key to esthetic success and is essential in satisfying the patient’s needs. By following the rules of Golden proportion smiles can be made attractive, harmonious, symmetrical, and proportionate. Methodology Consisted of 22-year-old girl who came for treatment of crowding in maxillary and mandibular arches, abnormal overjet and overbite and had unesthetic peg lateral. Results Non-extraction therapy was carried out since the patient had good soft tissue drape, alignment was achieved by expanding the arches and moving teeth in ideal axial inclination. Esthetic smile was attained using composite buildup of upper right peg lateral and minor adjunctive surgery (full thickness periodontal graft) on lower right central incisor. Conclusion The present case report orchestrates interrelationship between various branches of dentistry and orthodontics. It exhibits how multidisciplinary approach can be used to achieve ideal dental esthetics in a 22-year-old girl who was successfully treated for peg shaped lateral incisor, gingival recession, and unesthetic smile., Video abstract

Aim: The study aimed at assessing awareness about their own orthodontic treatment need and their perceptions about the dental attractiveness in school children. Subjects and Methods: The random sample of 200 school children (126 boys, 74 girls), aged 9-16 years was selected and categorized into eight different groups according to their occlusion after the dental check-up. Their own orthodontic treatment need and perception of the dental attractiveness was assessed by using questionnaire and was scored by showing eight intraoral frontal photographs and assessing their responses. Statistical Analysis Used: Chi-square test. Results: About 86% of school children considered well-aligned teeth important for overall facial appearance. School children scored photos having severe crowding (95.5%), highly placed canine (86.5%), and Class II Division 2 (70.5%) as most unattractive. 69.5% students did not feel the need of orthodontic treatment and 14.5% students did not know about orthodontic treatment. Conclusion: The study concluded that after showing positive perception toward dental attractiveness, when similar malocclusion was observed in them, they did not feel the need for orthodontic treatment due to lack of awareness. The study emphasizes the need to increase awareness especially among school children about different malocclusion and importance of orthodontic treatment as it is advantageous in preventing further complications.
