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

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 :

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

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.

ABSTRACT:

Introduction:

Orthodontists must take precautionary measures to protect patients from cross-infection as most materials supplied by manufacturers are not sterile.

Materials and methods :

A sample of 108 as received brackets, molar tubes and archwires equally divided in four groups (3 experimental groups, Group 1- Chlorhexidine Gluconate, Group 2 – Povidone Iodine, Group 3 - Glutaraldehyde and one Control (group 4) were used in this study. Three samples of each (brackets, archwires, molar bands) were tested for CFUs of each micro-organism (Staphylococcus aureus, Streptococcus mutans, and Lactobacillus acidophilus) in each group. The samples were incubated and spread on blood agar and the colony forming units (CFUs/ml) enumeration were done before and after disinfection.

Results:

Brackets and molar bands had least CFU/ml of Staphylococcus aureus after disinfection in Group 3 (p=0.000). Of allthe materials contaminated by Streptococcus mutans (p= 0.000) andLactobacillus acidophilus, the mean CFUs/ml were least in Group 2 ( p<0.05).

Conclusion:

2% Glutaraldehyde was effective against Staphylococcus aureus. 5% Povidone iodine was effective against Streptococcus mutans and Lactobacillus acidophilus. The antimicrobial activity of 5% Povidone Iodine was most effective followed by glutaraldehyde when compared to chlorhexidine gluconate.

Abstract:

Genetic etiology of Skeletal Malocclusion has been explored extensively over recent years with the advent of advances in molecular technologies. Studies have reported that the masticatory muscles regulate skeletal development and few recent works of literature report that the muscle growth regulators influence the facial proportions in sagittal and vertical dimensions in Skeletal Class II malocclusion. This review is a humble attempt to highlight the role of one such muscle gene known as ACTN3 and its association with Skeletal Class II malocclusion.

Abstract

Aim:

This case report represents the clinical management of a Skeletal Class II adult patient with gummy smile treated by Orthognathic surgery.

Background: 

Vertical maxillary excess (VME) is the most common skeletal deformity in Skeletal Class II which is treated by Anterior Maxillary Osteotomy (AMO) and Gummy Smile is the characteristic feature of VME in which the anterior part of maxilla is superiorly repositioned. 

Case Description: 

A 19-year-old patient reported our clinic with the complaint of forwardly placed upper front teeth. On extra oral examination, she had convex profile with posterior divergence and interlabial gap of 10mm and everted upper lip. The patient had a gummy smile of 8mm. Intra orally, she had Class II canine relationship on both sides with missing irt 16, 36, 46. Cephalometric values showed Class II skeletal base with protrusive upper and lower incisors and acute nasolabial angle. Initially orthodontic treatment was done and extraction of upper first premolars was planned during surgery. AMO was done with superior impaction of 4mm and posteriorly by 6mm. After 4 weeks of post surgery, the settling of occlusion using intermaxillary elastics was done. At the end of the treatment, the patient had Class I canine relationship on both sides with Skeletal Class I and overjet and overbite was 2mm. The patient gummy smile was reduced to 4mm which was accepted by the patient. Fixed retention was given in both the arches. The total treatment time was around 30 months. 

Conclusion: 

The proper diagnosis and appropriate treatment planning is the main key to achieve stable results in Orthodontics. An interdisciplinary approach with the orthodontist and surgeon will lead to achieve stable, functional and esthetic results.

Abstract:

Aim:

White spot lesions are one of the main drawbacks of fixed orthodontic mechanotherapy. Probiotic bacteria have been included in mouthwashes and lozenges to check the activity of S.mutans on surface enamel. Aim of the present study was to evaluate and compare shear bond strength and adhesive remnant index scores of orthodontic brackets bonded with probiotic impregnated (Lactobacillus rhamnous) orthodontic adhesive and conventional light cure orthodontic adhesive.

Materials and methods:

In this in-vitro study,two groups were tested in one group brackets were bonded to extracted maxillary premolars using probiotic impregnated composite and in the other with conventional light cure composite resin.Shear bond strength was assessed using universaltesting machine. Adhesive remnantindex scores were assessed on the same samples.

Results:

Shear bond strength of the new composite resin was significantly decreased when compared to conventional light cure composite(p=0.001). There was no significant difference in ARI scores (p=0.51) between the groups.

Conclusions:

The shear bond strength of the novel probiotic impregnated composite was significantly reduced. Though there was no significant variation in ARIscores when compared to control, avenues to improve the shear bond strength should be assessed.

ABSTRACT

“Surgery First Approach” (SFA) is a growing trend that provides an immediate facial change. The SFA protocol utilizes the dentoalveolar compensations as an advantage to effect immediate facial changes, which in conjunction with the Regional AcceleratoryPhenomenon enhances the tooth movementthereby reducing the total treatment duration. The post-surgical orthodontic phase is often complicated by rapid accelerated tooth movement producing a non-predictable nature of tooth movements. With the combined application of temporary anchorage devices these movements are made predictable in three dimensions. This case report illustrates the treatment of a skeletal Class II patient with a combination of the SFA protocol and TAD-aided orthodontic treatment. A 19- year-old female presented with proclined upper anteriors and retrusive lower jaw. Clinical examination revealed a severe lip incompetency, mandibular deficiency, Class II skeletal malocclusion, severe bimaxillary incisor proclination, severely crowded mandibular arch on a low mandibular plane angle. The SFA protocol involving BSSO advancement and genioplasty was performed, followed by an orthodontic phase involving TADs. The total treatment time was 14 months, following which excellent facial change and stable occlusion was achieved. A three year follow up is also presented.

Abstract

Aim:

To evaluate and compare the effectiveness of two different manual toothbrushes on gingival health among patients undergoing orthodontic treatment.

Methodology:

In the present randomized cross-over controlled trial, 60 subjects were recruited, to receive either crisscross or multilevel bristle design. Modified Gingival Index (MGI), Modified Silness and Loe Plaque Index, and Gingival Bleeding Index (GBI) and were assessed for 120 days. Statistical analysis was done using SPSS version 21 (SPSS; Chicago, IL, USA). Owing to the ordinal nature of the indices, non-parametric tests of significance were used.

Results:

The efficacy of the two-bristle design brush showed an overall reduction in the mean score. Overall significant differences were seen in the efficacy of the two different bristle designs. Both the study groups showed a reduction in the mean MGI, PL, and GBI with a P value less than 0.001 which was statistically significant.

Conclusion:

In the present study, the criss-cross bristle design was found to be significantly more effective as compared to the multilevel toothbrush design for reducing MGI, PL, and GBI scores.

Abstract

Introduction

Cephalometry used as an adjuvant tool in orthodontic diagnosis has undergone significant changes from manual tracing to computer assisted digital tracing cephalometric analysis system. The smart phone apps running in android or other operating systems were introduced recently for doing cephalometric analysis. Hence this study was done comparing the accuracy and reliability of automated tracing (Webceph Android app) with gold standard manual tracing and semi-automatic tracing (NemoCeph).

Materials and Methods

The study was performed on 39 Pre-treatment lateral cephalograms. 10 angular and 11 linear skeletal, dental and soft tissue parameters were assessed by tracing the cephalograms manually, digitally using Nemoceph software and Webceph app. The mean and standard deviation were calculated, the overall intergroup comparisons were done using ANOVA test and individual intergroup comparisons were done by post-hoc analysis using Sidak Test. The overall interclass correlation coefficient (ICC) was calculated between the three groups.

Results

Angular measurements such as Occlusal plane to SN (P< 0.05) and Nasolabial angle (P< 0.05) showed significant difference between the different tracing methods and the linear parameters such as N perpendicular to Point A (P< 0.05) and Wits Appraisal (P< 0.05) showed significant difference between the different tracing methods. The overall reliability statistics showed good agreement (P<0.05) among all three groups.

Conclusion

Automated tracing (WebCeph) had more landmark identification errors when compared with manual or semi- automatic tracing (Nemoceph). Both WebCeph and Nemoceph were superior in their reliability when compared to manual tracing, with Nemoceph demonstrating greater efficacy compared to WebCeph.

Abstract

Smile esthetics is a prime concern in contemporary orthodontic therapy. This case report is about a growing female patient with the inability to close the lips, vertical maxillary excess and hyperdivergent class II skeletal pattern. To enhance skeletal therapy benefits , differential intrusion of segments in the upper arch was required. Bilateral Bollard type miniplates were inserted on the infrazygomatic crest . The technique employed helped this patient avoid orthognathic surgery by allowing a complete upper arch intrusion, treating lip incompetence and causing counterclockwise movement of the mandible.

ABSTRACT

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. Key Words: Facial pattern, Anchorage loss, Extraction effects, vertical dimension.

Abstract:

Background:

Periodontitis is the result of inflammation caused due to the activity of microorganisms. The prevalence of anaerobic organisms is more when it comes to periodontal pockets and orthodontic patients. Plants with phytochemicals that could exert antimicrobial effects could aid in host modulation for management of periodontitis caused by these bacteria in periodontal and orthodontic patients.

Aim:

To assess the antimicrobial effect of aqueous extract of Moringa oleifera Lam (MOL) and cytotoxic effect of aqueous and ethanol extracts of MOL.

Materials and methods:

Moringa oleifera Lam. extracts were prepared by maceration. Subgingival plaque samples were collected, and microorganisms were cultured in anaerobic environment. The microorganisms were treated with the extracts and minimum inhibitory concentration and minimum bactericidal concentration was assessed. The cytotoxic effects were assessed by brine shrimp assay.

Results:

Aqueous extract showed antimicrobial effect in dose and time dependent manner and both extracts exhibited cytotoxic effects in a dose and time dependent manner.

Summary and Conclusion:

The antimicrobial effect of MOL could be utilized to develop a nature derived local drug delivery system for treating plaque induced periodontitis in different clinical situations.
