Abstract

Introduction: The COVID-19 pandemic situation has affected all professions including orthodontics. The present study proposed determination of impact of irregular appointments on Orthodontic treatment amid COVID-19 pandemic.

Materials and Methods: The cross-sectional observational study design enrolled 134 patients over period of 2 weeks were recorded such as treatment start date, total number of appointments scheduled and frequency of missed appointments after 24 March 2020, Stage of Orthodontic treatment on or before 24 March 2020 i.e., Alignment & levelling b) Space closure c) Finishing and Detailing d) Retention.

Results: The distribution of malocclusion based on Angle Molar criteria showed prevalence of 53.73 % Class I, 37.32 % Class II and 8.95% Class III. The malocclusions were treated predominantly by extraction in 57.46 % and non-extraction in 42.44 % patients. The total treatment duration revealed that more than 51 % patients’ treatment lasted beyond 24 months but finished before 36 months. Similarly, 35.82 % patients’ treatment duration was less than 12 months. It was found that more than 47 % were in Stage I, 28.36 % were in stage II, 18.66 % in stage III and lastly 5.97 % were in stage IV.

Conclusion: Orthodontic emergencies and un-schedule appointments had prevalence of Class I, followed by Class II and Class III with extraction treatment therapy. Majority patients treated with fixed mechanotherapy followed by Clear aligners and Retainers. More than half of the patients had increased treatment duration due to irregular follow up.

Abstract

Introduction: The effect of headgear on the space available for the eruption of upper third molars needed further investigation. Only a few studies looked at the after-treatment effect of headgear on that space, and none have evaluated the long-term effect after the average age of third molar eruption. Therefore, this retrospective study evaluated the short and long-term effects of cervical headgear on the space and eruption of the maxillary third molars and their long-term eruption status.

Materials and Methods: Records of Class II cases treated with cervical headgear were collected at the following time points: (T1) before treatment, (T2) after treatment, and (T3) taken at least 4 years after T2. An untreated control sample was collected from the Bolton-Brush study records. They were matched for age at each time point and malocclusion. Lateral cephalograms were used to measure the distance from the distal surface of the maxillary first molar (U6) to the pterygoid vertical plane (PTV). The third molar status at T3 was categorized into five groups: impacted, extracted, erupted, congenitally missing, and formation stage. Thirty-three cases were included in the cervical headgear group and 19 in the control group.

Results: The position of U6 changed significantly between the headgear and control group at T2 but was similar at T3. In the headgear group, the U6 was significantly distalized (3.3 ±2.9 mm) between T1 and T2 (P=0.006), however, there was a significant relapse of 5.9 (±4.6) mm between T2 and T3 (P<0.001). In the control group, the distance between U6 and PTV increased significantly from T1 to T2 (4.8 ±4.4mm) with minimal change from T2 to T3 (1.5 ±4.8mm). There was no significant relationship between headgear use and third molar status (p=0.108).

Conclusion: Headgear caused a temporary decrease in the U6-PTV distance that was recovered later. This decrease was not observed in the control group. Using cervical headgear to correct Class II malocclusion does not increase the risk of upper third molar impaction.

Abstract

Aim: To investigate the perception of dental caries risk and prevention among patients undergoing orthodontic treatment and to assess the influence of the oral hygiene information attained during orthodontic visits on patients’ perception of dental caries prevention.

Methods: A cross-sectional questionnaire gathered information from 207 orthodontic patients (aged 18 and older). The questionnaire included questions about patients’ demographics, perception of dental caries risk and prevention during orthodontic treatment, and oral hygiene information received in orthodontic visits. Frequency distributions of responses were evaluated. Chi-square test was used to assess the differences in patients’ perception of dental caries prevention by demographics, and the oral hygiene information received during orthodontic appointments.

Results: 74.9% of orthodontic patients perceived to be responsible for dental caries during orthodontic treatment, and 30.4% of patients perceived that it is abnormal to develop dental caries during treatment. Patients receiving information about tooth brushing methods and oral hygiene accessories during orthodontic appointments had a better perception of appropriate oral hygiene in preventing dental caries (P= 0.01 and P= 0.04, respectively). Moreover, patients receiving dietary information during orthodontic appointments had a better perception of supporting a good diet and avoiding sweets in preventing dental caries (P< 0.001 and P= 0.02, respectively).

Conclusion: There is a need to improve orthodontic patients’ perception of their risk of dental caries during orthodontic treatment and the manners that would help to avoid new decay lesions. Orthodontists should not underestimate the value of providing and reinforcing oral hygiene instructions throughout the course of orthodontic treatment.

Abstract

Photodynamic therapy in fixed orthodontic patients with gingival disease might be beneficial, being non-invasive and having accessibility to difficulty to reach areas like, interdental region with the presence of wires and brackets. This systematic review was designed to analyze the available evidence on the efficacy of antimicrobial photodynamic therapy as an adjunct to scaling in reduction of gingival inflammation in periodontally diseased subjects undergoing fixed orthodontic treatment. Comprehensive search was conducted in electronic databases like PubMed, Scopus and Google scholar along with hand search in relevant journals. Five studies satisfied the criteria and were included in qualitative synthesis of the systematic review. The results of the primary outcome showed adjunctive aPDT did not result in any difference in reduction of gingival inflammation (BOP) compared to scaling alone in fixed orthodontic patients. Only one study showed a significant reduction of gingival inflammation with aPDT, whereas it was better in the scaling group (one study) or no significant difference (3 study) in the other studies. However, aPDT resulted in significant reduction of most of the bacterial species count and proinflammatory cytokine levels in GCF compared to scaling alone. Within the limitations of this systematic review, there is no clear evidence that aPDT adjunctive to scaling has a better effect in reducing gingival inflammation in fixed orthodontic patients. Future studies addressing this area should focus on well planned standardized, long term RCTs that will aid clinicians in making a more evidence - based decision.

ABSTRACT

There are a number of techniques with which such horizontal impactions can be treated, with no single technique being favored over the other, as these all have pros and cons. Horizontally impacted third molars are usually indicated for extraction, and only in situations where the first or the second molar has to be extracted due to decay is when these are uprighted for replacement of the missing teeth. In contrast to vertically impacted molars, there is a higher chance of success in uprighting horizontally impacted third molars as the cause is lack of space or blockage of the eruptive pathway.

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.

Abstract

BACKGROUND:

1,25 dihydroxycholecalciferol, the active form of vitamin D3 is known to play an important role in mineralization. Vitamin D3 is also known to have immune-supporting properties by regulating various cytokines and cell signalling pathways.

AIM:

To review the role of 1,25-dihydroxycholecalciferol (Vitamin D3) on the rate of Orthodontic tooth movement.

METHODS:

This study applied a systematic review to analyse the current literature to define and summarise the role of I,25-dihydroxycholecalciferol on the rate of Orthodontic tooth movement. A comprehensive search was done using electronic databases such as PubMed Central, Cochrane Database of Systematic Reviews, Google Scholar, EMBASE and direct web search. The title scan was done to identify relevant articles which are further evaluated for inclusion by reading the abstract.

RESULTS:

The electronic database search identified 28 articles. 3 articles were selected based on the selection criteria to meet the research question. There was about 60% faster rate of orthodontic tooth movement when a dosage of 40-50 pg/dl of 1,25 dihydroxycholecalciferol was supplemented. Administration of 1,25-dihydroxycholecalciferol showed no deleterious effects to the tooth roots or the surrounding tissues as evidenced from the periapical radiographs and CBCT.

CONCLUSION:

Based on the collected data, the local administration of an active form of Vitamin D3, 1,25-dihydroxycholecalciferol can act as an effective supplement to accelerate Orthodontic Tooth  Movement (OTM).

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:

Successful orthodontic treatment depends on the adhesive used for bonding orthodontic brackets and patient cooperation. Resin based adhesives are conventionally used but have drawbacks like white spot lesions and technique sensitivity. To overcome these problems, Resin modified glass ionomer cements (RMGIC) were introduced to utilise the fluoride releasing characteristic of GIC.

Aim:

To compare and evaluate bond failure rate and type of bond failure between brackets bonded with RMGIC and composite.

Materials and methods:

25 patients undergoing orthodontic treatment were included and evaluated for 6 months. Bonding was done with RMGIC and composite. Patients were recalled every month and bond failure rate and type of bond failure was evaluated.

Results:

A total of 526 teeth were bonded out of which 263 were bonded with RMGIC and 263 with composite. Statistical analysis was done with Chi-square test (p>0.05). Maximum debonding was seen in RMGIC group (6.46%) compared to composite (3.42%). Maximum debonding was seen in 1st molars bonded with RMGIC (35.3%). Majority bond failure type observed was Adhesive enamel failure in brackets bonded with RMGIC.

Conclusion:

From the study, it can be concluded that bond failure was commonly seen in RMGIC group in comparison with composite group. Adhesive enamel failure was the most commonly seen bracket failure type. RMGIC had majority bracket failure but within acceptable range and hence can be used as a substitute adhesive for bonding.

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.

Keywords: Melatonin, Bone remodelling, Pineal hormone, Osteoblast, Osteoclast, Orthodontics.

Abstract

Introduction: 

The most hidden and inaccessible of all the paranasal air sinuses is the sphenoid sinus, a cavity with an irregular shape that is situated in the middle of the cranial base. Since the anterior cranial base shows little growth after the age of 7, it is regarded as a stable reference for cephalometric analysis.
Objective: The aim of this study was to predict skeletal malocclusion by correlating the length of the cranial base and the volume of the sphenoid sinus in different sagittal skeletal patterns.
Materials and methodology:

In this study, a total of 30 cone beam computed tomography (CBCT) scans of patients, aged between 18 and 35 years who underwent orthodontic and orthognathic treatment were evaluated. DICOM files from the CBCT scans were imported and viewed using Dolphin imaging software. Skeletal malocclusion was evaluated using a lateral cephalogram obtained from the CBCT. Volumetric analysis of the sphenoid sinus and length of the cranial base was evaluated with the help of the Dolphin imaging software. A normality test was done to decide the statistical method for data analysis. A one-way ANOVA with Tukey’s post hoc test was done to compare the three groups.
Results:

There was a correlation noted between the volume of the sphenoid sinus in skeletal class II malocclusion but no correlation was noted in the length of the cranial base. The mean value of the volume of the sphenoid sinus in subjects with class II skeletal malocclusion was 12613.50± 2023.409 which was greater compared to the other skeletal malocclusions.
Conclusion:

Sphenoid sinus volume was reported to be increased in subjects with skeletal class II malocclusion but there was no correlation between the cranial base length and sphenoid sinus volume in any group.

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

Abstract

BACKGROUND

Early diagnosis of malocclusion and intercepting the malocclusion at an earlier stage is inevitable in orthodontics. The morphological characteristics of palatal rugae are set up at an early age and are stable in their position and pattern throughout the life of an individual, hence they are used as a reference landmark for superimposition and evaluate the extent of tooth movement in orthodontics. This review aims to analyze the orthodontic literature regarding the association of palatal rugae pattern with different malocclusion.

MATERIALS AND METHODS

To analyse the literature regarding the association of palatal rugae pattern with different malocclusion by using the keywords palatal rugae or plica palatine transversae or rugoscopy and malocclusion or sagittal malocclusion or class I or class II or class III or skeletal pattern and stability and orthodontics or orthodontia. The pubmed, Google scholar, Embase databases were searched till June 2022.

RESULTS

Wavy and Curved type of rugae was more common rugae pattern in all group of malocclusions. Many studies found there is no statistically significant difference in palatal rugae among malocclusion. However, few studies showing that largest number of rugae is present in class II malocclusion than class I and class III.

CONCLUSION

This review provides evidence of a distinct pattern of Palatal rugae in Class I and Class III malocclusion and largest number in Class II but to ascertain its statistical significance, further research is needed with a larger sample size.

Abstract

AIM: To quantitatively evaluate and compare the body posture and its correlation with cervical posture and plantar pressure in subjects with skeletal class II malocclusion, before and after camouflage orthodontic treatment.

MATERIALS AND METHODS: 18 subjects were considered for the study and subjected to lateral cephalograms and body posture analysis before and after camouflage orthodontic treatment. Cranio-cervical angles were compared before and after treatment using paired T test. A force platform was designed to accommodate the feet with pressure sensors placed at hallux, first metatarsal and medial calcaneus regions to record the loading pressure. The plantar pressure distribution values were correlated with the cranio-cervical angles.

RESULTS: There is statistically significant difference (p value <0.05) in the ANB angle, GoGn/OPT angle between pre and post camouflage orthodontic therapy indicating over extension of the head over the spinal column. Post treatment Pearson correlation coefficient indicates that the cervical curvature (OPT/CVT angle) has a negative correlation with the plantar pressure at medial calcaneus region. However, high statistical significance was found in the plantar pressure distribution before and after orthodontic treatment at all three regions.

CONCLUSION: Cervical curvature increased after camouflage orthodontic therapy, indicating over extension of the cervical spine. Plantar pressure reduced in the hallux, first metatarsal and medial calcaneus regions. The recorded value at the hallux region elicited considerable reduction indicating a shift in the plantar pressure from the most anterior region to the central region.
