Objectives: Primarily, to compare anchorage loss and changes in mandibular plane (MP) angle, overbite, and amount of horizontal, vertical, and angular movements of maxillary incisors in groups of hypodivergent, hyperdivergent, and normodivergent patients. Secondarily, to analyze the relationship between those factors. Methods: Pre- and post-treatment cephalograms of 89 patients treated with extraction of four bicuspids or two maxillary bicuspids were analyzed. The sample was divided into three groups based on their facial pattern measured by SN-MP angle (hypodivergent: < 270, hyperdivergent: >380, and normodivergent: 270-380). Linear and angular measurements included the distances of U1 tip and U6 mesial height of contour to Y-axis (i.e., line perpendicular to the X-axis, passing through Sella turcica), distance of U1 tip to Sella on X-axis, overbite, angulation of U1 to palatal plane, and SN-MP and ANB angles. Inferential statistics included one-way ANOVA, Chi-square test, independent t-test, and Pearson’s correlation coefficients. Results: Facial morphology did not primarily affect anchorage loss, because other factors such as crowding, severity of Class II molar relationship, and extraction modality played more impactful role (P< 0.01). Change in mandibular plane angle was neither influenced by, nor correlated with, initial facial morphology or anchorage loss (P> 0.05). Positive change in overbite was significantly correlated with facial pattern, incisor extrusion and retroclination (r= 0.30, 0.44, and -0.35, respectively, P< 0.01). Conclusion: Anchorage loss in extraction orthodontic treatment is not influenced primarily by initial facial morphology. Anchorage loss is not significantly associated with MP angle reduction. Change in overbite can be achieved through incisor extrusion and retroclination.

Class II malocclusion is one of the most commonly occurring conditions, and the component mostly involved is mandibular retrognathism. The treatment modalities include both removable and fixed appliances. The advantage of fixed functional appliances is that it is not dependent on patient compliance. Various fixed functional appliances are available such as rigid, flexible, and hybrid. The present case series discusses a hybrid type of fixed functional appliance, i.e. Twin Force Bite Corrector appliance in three cases: A 15‑year‑old female patient with Class II malocclusion due to mandibular retrognathism, a 14‑year‑old male patient with Class II malocclusion due to mandibular retrognathism, and a 14‑year‑old female patient with Class II malocclusion due to mandibular retrognathism. The effects produced by this appliance are similar to the conventional fixed functional appliances such as Forsus, Herbst, and also it has a distinct advantage of quick chair-side fabrication and simple design.

Abstract: Aim: The present bibliometric analysis was conducted to find the evidence regarding microbial corrosion in dentistry since corrosion by whatever means affect the intraoral performance of the metallic appliances. Materials and methods: Material and methods: Dimensions software was used to search for published literature pertaining to the keywords “microbial corrosion” AND “dentistry”. Two reviewers assessed the articles in terms of year of publication, authors, country of origin, journal of publication, and the affiliated institutions of the authors as well as their collaborations and the most cited publications. Results: The search revealed a total of 3,118 articles between the years 2000 to 2022. The number of publications was on the rising pattern with a spike between 2004-2007, again with a small spike between 2014 and 2016 and then a steep increase from 2017 onwards. The publications were almost equally split between Engineering science and Medical Sciences. United States topped the list of countries with 378 documents with total link strength of 106224. Sao Paulo University topped the list in terms of organizations with total link strength of 12722. The journal of Anatomia Histologia Embryologia topped with 136 publications followed by Materials with 94 publications. Valentim from Brazil topped the authors with 22 publications. Conclusion: Microbial corrosion is needs equal concentration as any other forms of intraoral corrosion given that oral cavity is loaded with huge varieties of microorganisms with some of them known to cause microbial corrosion like sulfate reducing bacteria. The recent decline in research and publications in this field especially in 2022 is concerning. More studies are needed to learn more on microbial corrosion and its effects in dentistry.

AIM : To evaluate the release of zinc and copper ions from zinc oxide and copper oxide nanoparticles coated orthodontic brackets in artificial saliva under Invitro condition. METHODOLOGY : Thirty six metal brackets were coated with copper oxide (group A) and zinc oxide (group B ) nanoparticles using spray pyrolysis method and bracket was randomly selected and assessed under scanning electron microscope. The nano-coated brackets with copper oxide and zinc oxide nanoparticles (Group A and B) were bonded on the extracted first premolar tooth with standard protocol and immersed in artificial saliva at pH of 6.5. The nanocoated brackets were analysed for ion release using atomic absorption spectrometer at four different time intervals baseline, day 7, day 14, and day 21 under invitro condition. RESULT : The highest concentration of zinc ion released from the zinc oxide and copper oxide nano coated brackets in the artificial saliva was on the 7th day and the quantity of zinc ion released was well below the levels that are toxic to humans throughout the study period. CONCLUSION: The concentration of zinc ions released zinc oxide nano coated brackets was significantly greater than the concentration of copper ion released from the copper oxide nano-coated brackets in the artificial saliva under similar experimental conditions.

Aim: The aim of this study was to evaluate the load-deflection rate of four different types of archwires used in initial stage of orthodontic treatment. Materials and methods: A modified three-point bending test was performed on the sample of 60 wires of superelastic Nickel Titanium(NiTi), everwhite esthetic NiTi, thermal NiTi and multistranded coaxial stainless steel (15 each). The load exerted by each of the wire was measured at the deflections of 2 mm and 4mm, subsequent unloading process at 37°C temperature. Results: Comparison of mean load-deflection values revealed that thermal NiTi wires had lowest value at both 2 and 4mm deflection when compared to other three wires which was statistically significant(p=0.009). Superelastic and esthetic NiTi showed similar values of load deflection ratios at both the deflections where as co-axial wire showed 1.89N at 2mm and 5.22N at 4mm deflection. Conclusion: The heat-activated NiTi wires are acceptable in severe crowding and periodontally compromised patients. Multistranded co-axial wire is acceptable when we need minimal alignment; whereas esthetic NiTi wires can replace superelastic Niti based on patient’s need.

Introduction: Various appliances used in orthodontic treatment behave as plaque retentive sites which can harbor anaerobic microorganisms and this may be associated with a worsening of preexisting periodontal diseases or induce a variety of other conditions. There are contrary reports regarding the increased load of anaerobes during orthodontic treatment. This review aims to analyze the orthodontic literature regarding the prevalence of anaerobes before, during and after orthodontic treatment.Objective: To analyze the literature on the prevalence of anaerobic microbiota and its relationship with orthodontics by using the keywords “anaerobes” OR “anaerobic microbiome” OR “red complex bacteria” AND “orthodontic” OR “fixed appliance”.The Pubmed and Embase databases were searched till January 2022.Results: Orthodontic treatment increases the prevalence of anaerobic microbiota especially the orange and red complex bacteria. The removal of orthodontic appliances has shown a significant reduction in plaque along with the corresponding anaerobic pathogens.Conclusion: Proper maintenance of good oral hygiene during orthodontic treatment is essential to reduce the anaerobic microbial load, thus diminishing the risk of periodontal problems.

The management of impacted canines is a complex task and requires a lot of time to guide them into the arch. In recent years the use of a Kilroy spring has become very popular and usually involves the use of a heavy main archwire and an auxiliary wire to guide the canine. In this case, a modified version of the Kilroy spring was fabricated on the main archwire, thereby reducing the need for a second auxiliary wire and allowing for the easy guidance of the impacted canine into its normal position into the arch.

Background: Rakosi jarabak analysis has been proved to be effective in predicting the facial growth pattern, morphological characters, reaction to various orthopedic approaches, and functional alterations. Most of these established cephalometric values are based on average values for the Caucasian population. Whereas cephalometric values vary among different populations and have shown variations among different ethnic groups, gender, and age. The objectives of this paper are to develop Rakosi Jarabak cephalometric norms for the South Indian population and compare the measures to values from other ethnic groups. Materials and Method: Facad software was used to track the lateral cephalograms of 100 non-growing patients from the South Indian population who satisfied our inclusion criteria. Nineteen craniofacial parameters of Jarabak’s analysis were measured. Result: A comparison between the males and females of the South Indian population showed a significant difference between the three parameters. Comparison of the south Indian male, female values, and overall values with established norms of various ethnic populations showed significant differences among various parameters. Conclusion: This study establishes the south Indian ethnic norms for Rakosi Jarabak analysis. The south Indian norms vary from caucasian norms showing significant ethnic .These differences need to be considered when analyzing the cephalogram . These values will help in customizing treatment plans based on ethnic norms.The study concludes that distivariationsnct sets of cephalometric norms should be developed for different ethnic groups in order to aid orthodontists and surgeons in optimising treatment plans based on local norms.
