As a repercussion of this stipulation, invisible orthodontic treatment has expanded its horizon. Efforts of using aesthetic brackets, wires, and lingual techniques to meet the expectations of adult patients have been practised. Though these techniques seemed to be promising in the initial days, soon decreased in popularity due to drawbacks associated with them. Clear aligners were offered as a newer and superior aesthetic alternative to overcome the difficulties associated with prior aesthetic approaches. These aligners are made up of different thermoplastic materials intended to move the malpositioned teeth in the desired corrected position following push mechanics. This article deals with new generation orthodontic treatment using aligners. It deals with history, generations, different materials used, and the distances yet to be travelled to become the benchmark and replace the existing conventional braces. This paper also gives a bird’s eye view of the method of aligner fabrication and the significant differences between the regular braces and aligners used in orthodontics.</p> Gopala Krishna Ganta Kamala Cheruvu Rama Krishna Ravi Raghavendra Prasad Reddy Copyright (c) 2021 International Journal of Dental Materials https://creativecommons.org/licenses/by/4.0 2021-08-01 2021-08-01 3 3 90 95 10.37983/IJDM.2021.3304 Mini-implants, mega solutions: a review https://ijdm.co.in/index.php/dental-materials/article/view/72 <p style="margin: 0cm; text-align: justify; line-height: 200%;"><span style="font-size: 10.0pt; line-height: 200%; color: #0e101a;">Dental implants have evolved as a standard treatment option for the replacement of missing teeth. Though this treatment modality provides a high level of patient satisfaction and success, it cannot be performed in all cases. Implant use is also restricted when the quality and quantity of bone at the edentulous site is limited, in addition to medically impaired patients. Among the conditions are remaining ridges with reduced interdental spacing, atrophic edentulous maxillary and mandibular ridges, and narrow ridges such as the mandibular incisor and maxillary lateral incisor area. A proper augmentation method for the placement of a regular diameter implant (3.75 to 7 mm) can improve the height and width of bone at such sites. However, bone augmentation and bone grafting procedures are rarely undertaken due to financial constraints, the risk of subjecting the patient to additional surgical procedures, the added time factor, or the guarded prognosis of the grafted site. In such cases, mini-implants are the choice of treatment. Mini-implants have the potential to be a viable alternative to standard-diameter implants in some circumstances. Benefits of mini-implants can be gained by replacing a single missing tooth, or preferably they must be used in multiples to retain fixed dental prostheses and might serve as an inexpensive, and efficient solution for retaining overdentures in selected cases.</span></p> Alaveni Manga Narsingoju C Ravi Kumar G Harilal Pavani Lukka Copyright (c) 2021 International Journal of Dental Materials https://creativecommons.org/licenses/by/4.0 2021-08-01 2021-08-01 3 3 96 99 10.37983/IJDM.2021.3305 An in vitro study to evaluate and compare the remineralizing potential among Casein Phosphopeptide-amorphous Calcium Phosphate (CPP-ACP) with fluoride and surface pre-reacted glass (S-PRG) fillers using quantitative analysis. https://ijdm.co.in/index.php/dental-materials/article/view/67 <p><strong>Background- </strong>Early treatment of white spot lesions is essential to prevent the progression of the lesion.</p> <p><strong>Aim - </strong>To evaluate and compare the remineralizing potential of CPP-ACP with fluoride (Casein Phospho Peptide-Amorphous Calcium Phosphate) and S-PRG fillers (Surface Pre reacted glass fillers) using atomic absorption spectroscopy and colorimetric method.</p> <p><strong>Materials and methods</strong>- Forty sound human premolars were used in this study. They were divided into two groups (A &amp; B), consisting of 20 samples in each. White spot lesions (WSLs) were established on the window (4x4 mm2) created on the buccal surfaces of the samples. Samples in group A were treated with casein phosphopeptide amorphous calcium phosphate (CPP-ACP) with fluoride, those of group B were treated with S-PRG Fillers. The sample teeth were immersed in a demineralizing solution for 4 days. All the samples were subjected to loss of mineral content (wt %), i.e., calcium, using atomic absorption spectroscopy and phosphorus using the colorimetric method.</p> <p><strong>Results</strong>- Statistical analysis was performed using one?way analysis of variance, Tukey’s and paired <em>t</em>?tests. Group A exhibited the highest remineralizing potential, followed by Group B. Statistically, a significant difference (p=0.001) was observed between the two groups. </p> <p><strong>Conclusion</strong>- There was a significant difference in remineralizing potential of CPP-ACP with fluoride and S-PRG Fillers. CPP-ACP with fluoride appears to be an effective technique in the remineralization of white spot lesions.</p> Shabista Jabi Swati Diwedi Vinod Upadhyay Ahsan Abdullah Mohammad Sarfaraj Ankur Mishra Copyright (c) 2021 International Journal of Dental Materials https://creativecommons.org/licenses/by/4.0 2021-08-01 2021-08-01 3 3 70 75 10.37983/IJDM.2021.3301 In vitro hydroxyapatite formation of a tetracalcium phosphate and anhydrous dicalcium phosphate based dentine desensitiser: TRIS buffer vs artificial saliva. https://ijdm.co.in/index.php/dental-materials/article/view/75 <p><strong>Background: </strong>Calcium phosphates (CPs) form hydroxyapatite (HA) in physiological solutions. These are commonly used to treat dentine hypersensitivity (DH) as they mimic the mineral composition of the natural tooth.</p> <p><strong>Aim:</strong> The present study aims to characterise the apatite formation ability of a commercially available calcium phosphate Teethmate<sup>TM </sup>(TM) in physiological-like media.</p> <p><strong>Materials and Methods:</strong> In this study, 4mm (D) x 6mm (L) cylindrical samples of TM were produced and immersed in tris(hydroxymethyl)aminomethane (TRIS) buffer (pH: 7.3) and artificial saliva (AS) (pH: 6.5) for up to 24 hours. This was followed by characterisation of the samples after immersion using <sup>31</sup>P magic angle - nuclear magnetic resonance spectroscopy (MAS-NMR), X-ray powder diffraction (XRD) and dentine treated with the material using scanning electron microscopy (SEM).</p> <p><strong>Results:</strong> <sup>31</sup>P MAS-NMR and XRD analyses revealed that samples immersed in TRIS buffer solution formed hydroxyapatite within approximately 6 hours of immersion. This change was observed at around 12 hours for samples soaked in AS. The pH of the immersion media increased with increasing immersion time. SEM analysis showed a transitional phase formation of structures exhibiting plate-like morphology.</p> <p><strong>Conclusion:</strong> This study shows that TM converts to HA <em>in vitro</em> rapidly and provides an effective option for the treatment of dentine hypersensitivity.</p> Tomas Duminis Saroash Shahid Copyright (c) 2021 International Journal of Dental Materials https://creativecommons.org/licenses/by/4.0 2021-08-01 2021-08-01 3 3 76 83 10.37983/IJDM.2021.3302 Evaluation of different custom angulated elastic glass fibre post on fracture resistance of maxillary central incisor: an in vitro study. https://ijdm.co.in/index.php/dental-materials/article/view/76 <p><strong>Background</strong>: Restoring Endodontically treated teeth (ETT) can be challenging for most dentists, particularly when a significant tooth structure is lost. Depending on the coronal tooth structure remaining and the technique used (direct or indirect), endodontic anchorage can involve either a cast post and core or a prefabricated post.</p> <p><strong>Aim: </strong>This study aimed to investigate the effect of different custom angulated, i.e.,0°,5°,10°,15° elastic glass fibre post (Everstick post) on fracture resistance of maxillary central incisors.</p> <p><strong>Materials and methods</strong>: A total of forty-eight single-rooted maxillary central incisors were selected. All the samples were decoronated 2mm above the CEJ and endodontically treated. Post-space preparation was done for all the samples using peesoreamers ranging in size from 1-3. The samples were then randomly divided into four groups (n=12) based on the different angulations, i.e., the angle between the core and the long axis of the root, with 0°, 5°, 10°, and 15° angulations, respectively. The fit of each post in the root canal was verified. Before cementation, the coronal part of each post was bent according to their respective groups. Dual-cure resin cement was used for luting the posts and cured subsequently. The fracture resistance of all the samples was evaluated using the universal testing machine after they were mounted in self-cure acrylic resin blocks. The data were analysed using One- way ANOVA and Tukey’s post-hoc test.</p> <p><strong>Results</strong>: Group I exhibited the highest mean fracture resistance compared to other groups. However, One-way ANOVA showed no significant differences (p=0.161) between the four groups.</p> <p><strong>Conclusion</strong>: Everstick fibre posts are a preferable alternative for maxillary central incisors with core angulations up to 15° between coronal and radicular segments as they provide better fracture resistance with a more favourable stress distribution.</p> Srikrishna Teja Marisetty K Madhu Varma Girija S Sajjan Vishal Babu Kolla K Nanda Kishore Mohammad Raheem Copyright (c) 2021 International Journal of Dental Materials https://creativecommons.org/licenses/by/4.0 2021-08-01 2021-08-01 3 3 84 89 10.37983/IJDM.2021.3303
