Abstract

Introduction: In recent years, there has been a revolution in the use of technology across all fields, including medicine and dentistry. Significant technological advancements are being made in the field of orthodontics, which have enhanced patient and practitioner experience overall. This study aimed to assess knowledge, awareness, and practice of digital orthodontics among orthodontists and orthodontic residents through a questionnaire.

Materials And Methods: This cross-sectional study collected data using 20 questionnaires (pretested and prevalidated) by the experts. The questionnaire consists of socio-demographic information (5 questions) and a section asking about knowledge (9 questions), awareness (5 questions), and practice (6 questions) about digital orthodontics. The Final sample size was 360. Following content validation, the completed questionnaire was forwarded over social media platforms to the Orthodontic Study Group and distributed to orthodontists and orthodontic residents, and responses were collected. The data was assembled, organized, and subjected to statistical analysis using SPSS, IBM version 20.0. A chi-square test was performed for the quantitative variables.

Results: The findings showed that most participants were aware about digital orthodontics, and they also showed a promising trend towards incorporating digital orthodontics into routine clinical practice. A statistically significant difference was present regarding the knowledge about digital orthodontics between males and females (p value=0.024).

Conclusion:  Orthodontic Residents and orthodontists demonstrated a positive attitude, acceptable knowledge, a good outlook and little experience with digital orthodontics.

Abstract

Objectives:

The objectives of this study were to ascertain the prevalence, distribution pattern, and root shape of dilaceration for each type of tooth, and to examine the association between dilaceration and gender.

Material and Methods:

The study was carried out at multiple centers- College of Dentistry at Hawler Medical University, Azadi Dental Center and Khanzad Teaching Center in Erbil City, from 2019-2023. 1420 patients received treatment and were assessed, of which 389 individuals (age range 17-45 years) satisfied the inclusion criteria. Among these, 143 were males (36.8%), 246 were females (63.2%). Three orthodontists conducted clinical examinations using standard diagnostic techniques. Cone beam computed tomography (CBCT) was utilized to determine the location of root deviation, whether it was in the apical, middle, or coronal third of the root.

Results:

Statistical analyses employed Pearson's chi-square test and Fisher's exact test. The occurrence of root dilacerations in the jaw was highest in the third molars (79.5%), followed by first molars (6.8%), second molars (6.8%), and second premolars (6.8%). Root dilacerations were most prevalent in the lateral incisors (40.2%) within the maxilla, followed by the canine (26.1%) and central incisors (14.1%). Females had a higher prevalence of tooth dilacerations compared to males. The majority of dilacerations occurred at the apical region (66.1%), with the middle region accounting for 30.6% and the coronal region accounting for 3.3%.

Conclusion:

Based on these findings, it is advised that orthodontists conduct a thorough examination of dilacerated teeth during orthodontic treatments. CBCT can serve as a supplementary technique for identifying the arrangement of root dilaceration. Our findings highlight the significance of doing a diagnostic radiographic evaluation prior to devising a treatment plan for permanent teeth.

Introduction: 

Nasolabial angle is composed of two components: a) upper and b) lower component. Various foreign authors have developed different methods for evaluating this but consistent and reproducible methods for Indian population are few. Therefore, this should be placed within acceptable limits by planning treatment procedures accordingly to get the best aesthetic profile result and patient satisfaction.

Aim of the study:

To evaluate upper and lower components of nasolabial angle in different malocclusions in Bhopal population.

Material and methods:

It is a retrospective study, of sample size 150 that comprised of 60 profile pictures of individuals who belonged to Bhopal, out of which 30 were selected as aesthetically pleasing. Their lateral cephalograms were taken and traced. The study also used 120 lateral cephalograms of different malocclusions. The recorded data was analyzed using one-way ANOVA Test.

Result:

Significant results with p value<0.001 were found for the nasolabial angle among ideal group, Class I bimaxillary protrusion, Class II Division 1 and Class II Division 2, Class I crowding.

Conclusion:

Nasolabial angle is correlated with the type of malocclusion and the soft tissue variables also alter this angle.

Abstract

Background:

Epigenetic regulators play a vital role in determining a complex phenotype. The Skeletal Class II malocclusion is one such phenotype, which is a polygenic, complex disorder. The identification of epigenetic regulators would aid in understanding the complex relationship between the epigenetic marks and the phenotype. Also, these epigenetic marks can be considered for developing diagnostic leads upon validation for a specific disorder.

Materials and methods:

The present study follows an observational study design, which was performed using computational tools. The preliminary data about the genes associated with the Skeletal class II malocclusion was derived from DisGeNet, followed by the identification of the protein-protein interaction networks. The microRNA targets were then identified using miRDB and the unique microRNA population common to all five genes was further curated using the Venn plot.

Results:

The DisGeNet database provided information on the genes that were associated with skeletal Class II malocclusion. The five genes identified were ACTN3, GH1, HDAC4, HMGA2 and KAT6B. One microRNA, hsa-miR-892c-5p was unique to ACTN3, HDAC4, and HMGA2. The hsa-miR-3925-5p and hsa-miR-590-3p were found to be common to the genes ACTN3, HDAC4, and GH1 + HMGA2 respectively.

Discussion:

The identification of microRNAs targeting candidate genes could aid in defining the role of these microRNAs in establishing the phenotype. The future scope of this study lies in curating microRNAs that are common to class II malocclusion-related candidate genes. This panel of differentially expressed microRNAs can further be developed as an early diagnostic marker, for identifying the skeletal abnormality that they would be possibly associated with.

Abstract :

INTRODUCTION:

Malocclusion and TMD were believed to have a correlation when it is associated that the alteration of form might cause alteration in the stomatognathic system function. A multidisciplinary approach is particularly important for the successful treatment of chronic TMD cases. Management of TMD involves the work of dentists from various specialities. It is multifactorial in nature and requires proper examination and treatment planning. Thus, the primary purpose of this study is to find out the awareness of TMDs among postgraduate students.

MATERIALS AND METHODOLOGY:

The present study was retrospective in nature. A questionnaire involving TMDs was sent to all postgraduates involved in patient treatment through google forms. All participants were asked to anonymously answer the structured questionnaire containing multiple-choice and open-text questions in google forms. The questionnaire was specially developed for students and was organized into three sections.

RESULTS:

204 participants responded and returned the completed questionnaires. Results showed that 98 % of the respondent’s occlusal disturbance causes TMD and TMJ problems are associated with malocclusion. The majority of the participants were aware of the aetiology and diagnosis but only 53% of them were aware of the treatment protocols.

CONCLUSION:

The causes and diagnosis domains of the questionnaire yielded a high degree of agreement while the treatment modalities were not known. Most of them were not aware of the treatment modalities reason being a lack of knowledge during the course of their undergraduate and postgraduate study.

Abstract

Objectives:

To investigate the effects of melatonin and its agonist on bone tissue through a systematic review of literature.

Materials and Methods:

The keywords [Melatonin OR Pineal Hormone OR Ramelteon OR Agomelatine OR Tasimelteon] AND [Bone OR Osteoblast OR Osteoclast OR Bone remodelling OR Bone Metabolism] were searched on Scopus, Web of Science, and PubMed. Title and abstracts were reviewed to exclude the duplicates and irrelevant articles. The full-text articles were then screened in accordance with the inclusion criteria.

Results:

Of the 963 identified articles [PubMed=788, Web of Science=122, Scopus=53], only 3 studies qualified to be included in the systematic review based on the inclusion criteria. The first study assessed effects of the oral melatonin on bone integrity and mass in postmenopausal osteopenic women. Whereas the other two evaluated the radiographic and clinical outcomes of dental implants with the local application of melatonin. All studies showed an improved outcome parameter in comparison with the control group. All three studies elicited a low risk of bias.

Conclusion:

This study suggests that melatonin has osteoinductive potential and has an inhibitory effect on osteoclasts, thereby improving the quality and rate of bone remodelling.

ABSTRACT

Background

Arch expansion is one of the non- extraction methods of gaining space. This study aims to assess and compare the arch expansion achieved during initial leveling and alignment with three different bracket-archwire combinations.

Material and Methods

This was a retrospective study done in a university setup. From the available patient information archives, records of 30 subjects based on their advocated bracket system were identified and categorized into three groups. Their pre-treatment (T0) and post aligning (T2) 3D model maxillary scans were superimposed according to the reference points marked on the third palatal rugae using an OrthoAnalyzer software (3 shape version 19.0) to assess the changes in inter-canine width (ICW), inter-premolar width (IPW) and intermolar width (IMW) and arch length. For the recorded data, descriptive statistics, One-way ANOVA and Tukey HSD post hoc were analyzed using SPSS software.

Results

In Group 1 with MBT prescription with conventional nitinol archwires, the intra-group comparisons revealed no significant change (p value = 0.180). In Group 3 with ceramic MBT brackets with HANT archwires, the intragroup comparisons revealed no significant difference (p value = 0.414). However, in Group 2- Damon self-ligating bracket with broad archwires, intra-group comparisons revealed significant differences in inter-canine and interpremolar widths (p value = 0.048 and p value = 0.044, respectively).

Conclusion

The study aimed at evaluating transverse maxillary arch dimension changes with different bracketarchwire combinations. Maximum changes in the transverse dimension at ICW and IPW were noticed among all the three groups with maximum in Group 2 (passive self-ligating bracket with broad archwires). Although the inter-group comparisons revealed no statistically significant difference, it was appreciated clinically in relieving dental crowding.

Abstract

INTRODUCTION: Bonding of buccal tubes to the tooth is an essential procedure in orthodontic treatment. With the increase in the number of adult patients seeking fixed orthodontic treatment, there is a need to find a more reliable procedure to bond the artificial crown surface. Successful orthodontic treatment requires sufficiently high and durable bond between buccal tubes and ceramic/zirconia surfaces. There is a need for a bonding agent which can provide maximum bond strength to all surfaces. This study aimed to assess and compare the shear bond strength and adhesive remnants of orthodontic buccal tubes to natural teeth, ceramic crowns and zirconia crowns using two different bonding systems.

METHODS: In this in vitro study, 60 extracted human molar teeth were randomly assigned to three groups (n=20) and then divided into two subgroups(n=10). Bonding of buccal tubes to enamel, ceramic and zirconia surfaces was done using Assure plus universal bonding resin and Enhance LC. The shear bond strength of buccal tubes to the enamel, ceramic and zirconia surfaces were determined by universal testing machine. The SBSs and ARI scores were statistically analysed with and Kruskal Wallis test.

RESULTS: The mean shear bond strength of buccal tubes to enamel, ceramic and zirconia surfaces bonded with Assure plus and Enhance LC was highest for enamel followed by zirconia surfaces respectively. Non-parametric Kruskal-Walli’s test found significant differences regarding the shear bond strength and adhesive remnant index (ARI).

CONCLUSION: Bonding of buccal tubes to enamel, zirconia, and ceramic surfaces with Assure universal bonding resin and Enhance LC provided adequate bond strength. Thus, it may be used for bonding of orthodontic buccal tubes to the artificial crown surfaces in the clinical setting.

Keywords: Zirconia, Ceramic, Assure plus, Enhance LC, shear bond strength
