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.

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.

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.
