Separation is an essential requirement to ease the placement of bands which requires an extra appointment; the article highlights a clinical pearl in the form of innovative use of Kesling separators as molar tubes to overcome the disadvantages of dislodgment and potential complications.

In orthodontic treatment, there is difficulty in finishing stage in teeth that need uprighting to obtain root parallelism. Horizontal uprighting spring is used to upright teeth (clockwise or counterclockwise) to avoid uptighting problems in the late finishing stage such as rebonding brackets and to overcome the lack of vertical slot in the bracket. Horizontal uprighting spring is fabricated in the 0.012-inch stainless steel wire. Moreover, the type of tooth movement and the moment/force ratio can be determined by the spring length and hooking point.

Introduction: The objective of this study is to assess and compare shear bond strength (SBS) using different bonding techniques in amelogenesis imperfecta (AI) cases. Materials and Methods: Totally 30 extracted premolars from AI cases and 10 premolars from normal cases were obtained. The first group of (10) normal samples was treated with 37% orthophosphoric acid (H₃PO₄), second group (10) of AI cases was treated with conventional technique (37% H₃PO₄), third group (10) with sodium hypochlorite (5% NaOCl), and fourth group (10) with 2% sodium fluoride (2% NaF). Brackets were bonded using Transbond XT light curing adhesive and SBS was measured using the Instron universal testing machine. Results: Statistically highly significant difference observed between the strengths of all four groups (P < 0.01) with the mean highest for control group followed by NaF conditioning and NaOCl conditioning and least for conventional bonding procedure in AI cases. On pairwise comparison using Tukey's post hoc test, statistically highly significant difference was observed between the mean SBS for control group versus Group 2, Group 3, and Group 4, Group 2 versus Group 3, and Group 2 versus Group 4. Conclusion: Brackets bonded by conventional technique showed lower SBS as compared to NaOCl and NaF in AI cases. The application of 2% NaF gel for 4 min before acid etching of hypomineralized tooth surface shows significantly higher SBS as compared to conventional and NaOCl group in AI cases.

The maxillary incisors are the most frequently fractured teeth which hamper the esthetic, functional, and psychological aspects of an individual. Of the many treatment options available, orthodontic space regaining and prosthetic implant for the replacement of missing central incisor is the best multidisciplinary treatment approach. This case report describes a 19-year-old female patient who reported with crooked appearance of upper anterior teeth due to loss of space in the right central incisor tooth area. The patient was treated with prosthetic implant in the space restored by orthodontics.

Objective: The aim of this study is to evaluate and compare salivary enzyme levels during orthodontic tooth movement with conventional brackets and self-ligating brackets. Materials and Methods: Twenty patients (15–25 years of age) where 10 patients treated with mechanical biological treatment prescription and 10 patients were treated with Damon prescription requiring after first premolar extraction participated in the study. The canine retraction was started with nickel-titanium (NiTi) coil spring with 0.019 × 0.025” stainless steel wire. Saliva sampling was done after initial alignment before retraction and at 1, 2, 3, 4, and 5 weeks after the application of orthodontic force. A volume of 5 ml of unstimulated whole saliva will be collected from the subject for each prescription. Aspartate aminotransferase (AST), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) enzyme samples will be analyzed with fully automated clinical chemistry analyzer model TOSHIBA 120R from Agappe Diagnostics. The salivary sample for tartrate-resistant acid phosphatase (TRAP) will be analyzed with the enzyme-linked immune sorbent assay (ELISA) technique ELISA. Results and Discussion: During canine retraction with NiTi coil spring the salivary enzyme levels for LDH and TRAP showed a significant difference from baseline to week 5 with Group A (conventional bracket) after the initiation of compressive orthodontic. The salivary enzyme levels for LDH, AST, TRAP, and ALP showed no significant difference from baseline to week 5 with Group B (self-ligating bracket) after the initiation of compressive orthodontic force. When compared between Group A and Group B at different time intervals for LDH, AST, TRAP, and ALP salivary enzyme levels, Group B showed a significant difference. The significant difference was seen with LDH at week 0 to week 2, AST at week 5, and TRAP at week 4, whereas ALP showed no significant difference. A significant difference with Group A was only seen with TRAP enzyme at week 1. Conclusion: The LDH, AST, TRAP, and ALP level in Group A showed a significant increase whereas Group B showed no significant difference after the initiation of orthodontic.

The science of smiling was initiated by Charles Darwin. He noticed that the causes, consequences, and manifestations of smiling are universal, whereas many other nonverbal body language behaviors such as gesture or touch differ between cultures and are therefore probably learnt. People express their emotions through smile and also it plays an important role in facial beauty. In this article, we will discuss various patterns of smile and factors influencing esthetics of smile.

Introduction: Malocclusion is a social handicap because of its negative physical, psychological and social impact on the people. Apart from the esthetic setback, malocclusion also affects the general health of a person by hampering the quality and quantity of food intake. Aim: The aim of the study was to evaluate the effects of malocclusion severity on oral health-related quality of life (OHRQoL) and food intake ability (FIA) in orthodontic patients. Methods: A total of 254 patients were assessed for the severity of malocclusion, OHRQoL, and FIA using standard oral health impact profile questionnaire and FIA questionnaire and their grades of malocclusion were assessed using the Index of Orthodontic Treatment Need- Dental Health Component Index. Results: Of the quality of life questionnaire, females are more affected in social disability than males (P < 0.001). Adolescents responded more positively toward their quality of OHRQoL. Conclusion: Severe malocclusion caused functional limitation, psychological discomfort, psychological disability, social disability, and physically challenged. The severity of malocclusion did not affect the FIA of the patient.

The orthodontic treatment is perhaps in terms of duration, the longest performed dental procedure. To accelerate tooth movement, orthodontists and periodontists together have worked out a successful technique termed as Wilckodontics, commonly known as periodontally accelerated osteogenic orthodontics. It is an emerging technology in the field of dentistry. Wilckodontics has solved the dilemma of rapid tooth movement by exploiting the dynamics of bone physiology and redirecting the emphasis in tooth movement to the manner in which the supporting bone responds to orthodontic forces. In this article, a 27-year-old male, with a Class I moderately crowded malocclusion, elected to undergo this new treatment option, due to the estimated reduction in treatment time. This case report shows one case of lower anterior crowding done using this technique. The total orthodontic treatment, from bracketing to debracketing, required exactly 6 months, with 12 orthodontic adjustments.
