Abstract

The use of clear aligners for molar distalization has been a hot topic in recent years. However, cases of bimaxillary molar distalization without temporary anchorage devices (TADs) are rarely reported. Dental crowding, one of the most common malocclusions in the Asian population, was often corrected by tooth extraction strategies in the past. Currently, in the application of molar distalization with clear aligners by orthodontic professionals, it becomes feasible to circumvent the necessity for tooth extraction or TADs in numerous cases that initially present as markedly crowded. A 29-year-old female sought treatment for dental crowding. Subsequent examination revealed that her upper dentition was moderately crowded, while the lower dentition exhibited severe crowding. The patient declined the extraction treatment option and requested clear aligners based on consideration of esthetics during orthodontic treatment. Drawing from the patient's chief complaint and specific requirements, an orthodontic procedure of bimaxillary molar distalization was implemented. Following the completion of clear aligner treatment, the patient achieved well-aligned teeth and a captivating smile, radiating enhanced esthetics. The satisfactory treatment outcomes confirmed the efficacy of clear aligners for molar distalization. With a well-considered anchorage plan, clear aligners can successfully achieve bimaxillary molar distalization without the necessity of TADs.

Abstract

Introduction: The transformation of the Metallurgy industry over the years has brought outstanding improvement in Nickel Titanium (NiTi) alloy, resulting into orthodontic NiTi archwires with improved properties, which are routinely employed during the initial phase of orthodontic treatment. Nevertheless, the clinical superiority between the second and third generation of NiTi arch-wires; the Super Elastic NiTi (SE NiTi) and Copper NiTi (Cu NiTi) archwires respectively has not been studied in the Tanzanian population. Hence, this study aimed to compare the clinical efficiency of Super Elastic NiTi (SE NiTi) and Copper NiTi (Cu NiTi) arch-wires during the alignment phase of orthodontic treatment.

Material and Methods: A total of 82 patients with an irregularity index of >2 mm on the mandibular anterior site were randomly allocated to one of the two treatment groups, group 1 (0.014-in SE NiTi) and group 2 (0.014-in Cu NiTi). Randomization was accomplished by random number generation via Microsoft Excel, participants were randomly assigned equally into respective groups. The arch-wire types were labeled and placed in sequentially numbered opaque sealed envelopes for participant allocation. Blinding to group assignment was applied to the participant and during outcome assessment. Data were analyzed by SPSS Statistics version 25 with a p-value set at <0.05.

Results: A total of 153 potential participants were evaluated for eligibility. 67 of those were excluded. Therefore 86 patients were randomly allocated to either the study control group (group 1, n=43) or intervention (group 2, n=43). The number of participants analyzed were n=42 in group 1 and n=42 in the control group. The Little's irregularity index significantly decreased over time in both groups (p<0.001), however, there was no statistically significant difference between the two arch-wires types in their efficiency on teeth alignment (p = 0.435) and arch width expansion (p>0.05).

Conclusion: There was no significant difference between SE NiTi and Cu NiTi in alignment efficiency and arch width changes. There was no statistically significant inter-canine arch width change in the Cu NiTi group.

Abstract

The case published in this paper provides a clinical explanation for the importance of MH setup. The casts were cut and teeth were set into wax rims using brackets fit on full engagement archwires. Then another set of brackets was set over the teeth after the necessary adjustments with another full engagement archwires using composite as custom-made bases. The final brackets were transferred to the patient using vacuum-formed indirect transfer trays and the treatment was commenced. The final results were ideal with a total treatment time of one year in an extraction case. The finishing phase was only one month with settling elastics without the need for any brackets modifications despite the class II full unit molar relationship.

Abstract

Aim: There is good evidence that orthognathic surgery improves quality of life (QoL), but it is uncertain whether QoL outcomes differ for patients with different dentofacial deformities. The aim of this study was to (i) assess changes in QoL before and after orthognathic surgery; (ii) compare QoL between deformity classes; and (iii) establish predictors of QoL

Methods: This was a prospective, longitudinal, observations study of adult patients seeking orthognathic treatment. Patients were classified into class II or class III dentofacial deformities. The paired t-test was used to compare Orthognathic Quality of Life Questionnaire (OQLQ) scores before and after surgery, and multivariable linear regression was used to identify predictors of post-operative OQLQ score. 

Results: Of the 50 participants, 36 (72%) were female, and the average age was 29.9 ± 4.2 years. Overall and domain OQLQ scores were significantly lower after surgery (p < 0.0001). The mean change in QoL score was significantly greater for class II patients (p = 0.003). Age and baseline OQLQ score were significantly associated with post-operative OQLQ score.

Conclusions: This study confirms that orthognathic surgery has a very positive impact on QoL. The finding that age and baseline QoL predict subsequent QoL outcomes paves the way for targeted interventions in specific patients.

Abstract

Objective : The aim of this in vitro study was to verify the accuracy of torque prescription in the buccal tubes of three commercially available molar bands using Play and Torque Measuring device and to quantify the amount of torsional play present in them.

Materials and Methods: A total of thirty preformed bands with 0.022 slot and McLaughlin-Bennett-Trevisi prescription were selected equally from three different brands for this cross-sectional in-vitro analytical study. The torsional play and torque of the molar bands were measured using the PTM device. The play and torque values obtained using the PTM device were used to calculate the play and torque using a formula. The play and torque values were measured for all the three groups. The mean values of play and torque obtained between three groups were measured using  One-way ANOVA.

Results: All three groups had variations in the torque and play that were above the standard torque and play values. There was a statistically significant difference in the play and torque values between all the groups  evaluated.

Conclusions : Orthodontists should be aware of the inherent manufacturing defects in the bands as this can prevent the achievement of ideal treatment results. This simple method can help us in determining the torque and play of the molar bands giving us better control over treatment mechanics.

Abstract

Background: Sagittal jaw discrepancies are a critical determinant in orthodontic diagnosis and treatment planning, necessitating an accurate assessment. This study aims to investigate the predictive efficacy of various sagittal parameters (ANB angle, Wits appraisal, Beta angle, Yen angle, and W angle) in diagnosing skeletal Class I malocclusion across diverse growth patterns.

Materials and Methods: A retrospective cross-sectional analysis was conducted using lateral cephalograms of 60 patients diagnosed with skeletal Class I malocclusion. Sagittal skeletal parameters (ANB angle, Beta angle, Yen angle, W angle, and Wits appraisal) were evaluated across three distinct growth patterns (vertical, horizontal, and average). Mean and standard deviation were calculated for each parameter within each growth pattern. One-way ANOVA with post-hoc Tukey's HSD test was employed for pairwise comparisons between groups. The inter-relationship between cephalometric parameters and growth patterns was assessed using Pearson's correlation coefficient, with statistical significance set at p ≤ 0.05.

Results: A total of 60 participants (30 males and 30 females) with a mean age of 18.60 ± 4.17 years were included in the study. Highly statistically significant differences were noted for Beta and Yen angle (p ≤ 0.001), whereas statistically significant differences were noted for ANB angle. The correlation test revealed a possible association between assessed parameters in the overall sample.

Conclusion: Angular and linear parameters revealed some degree of correlation in skeletal class I malocclusion patients irrespective of their growth pattern. However, the reliability of individual parameters in accurately classifying the skeletal discrepancies among different malocclusion states should be further investigated.

Abstract

White Spot Lesions (WSLs) are early signs of enamel demineralization, often occurring during orthodontic treatment due to hindered oral hygiene maintenance. Traditional treatment methods include resin infiltration or remineralization using fluoride-based agents. However, self-assembling peptides (SAPs), such as Curodont ™ Repair (P11-4), have emerged as potential alternatives for WSL management. This review comprehensively examines the chemistry, mode of action, clinical safety, and efficacy of SAP P11-4 in remineralizing enamel lesions. It synthesizes findings from studies investigating SAP P11-4's remineralizing potential using various assessment methods, including pH cycling models, laser fluorescence, digital subtraction radiography, and confocal microscopy. SAP P11-4, with its ability to mimic the enamel matrix and promote hydroxyapatite nucleation, demonstrates promising outcomes in reducing WSL size and progression. Clinical studies report significant improvements in lesion remineralization with SAP P11-4 treatment, often surpassing the efficacy of fluoride-based interventions. Moreover, SAP P11-4 shows compatibility with bonding procedures and potential for reducing dentin hypersensitivity. They offer a promising alternative or adjunct to traditional fluoride-based treatments for WSL management, providing clinicians with a valuable tool in promoting enamel health and preventing caries progression. Further research is warranted to explore long-term outcomes and optimize treatment protocols for maximum efficacy.

Abstract

Aim: To investigate the relationship between post orthognathic surgery changes in soft and hard tissue cephalometric variables in Class II and Class III patients and quality of life (QoL) measured using a condition-specific QoL questionnaire and to determine cephalometric predictors of the overall OQLQ after surgery.

Methods: The sample included 50 orthodontic patients, 28 Class II and 22 Class III skeletal relationships whose treatment included orthognathic surgery. Correlations between cephalometric changes and Orthognathic Quality of Life Questionnaire (OQLQ) were tested by Pearson’s correlation. Multiple linear regression was used to determine cephalometric predictors of the overall OQLQ after surgery.

Results: In Class II patients, OQLQ before surgery and changes in SNA were significant predictors for OQLQ after surgery. For Class III patients, OQLQ after surgery was significantly correlated with the change in mandibular plane angle and lower face height (r = 0.6 and r = 0.5 respectively). The decrease in facial angle was negatively correlated with OQLQ (r = -0.4). Mandibular plane angle, mandibular length, and OQLQ before surgery were significant predictors for OQLQ after surgery. 

Conclusion: QoL improved for Class II and III after orthognathic surgery. Changes in certain cephalometric measurements seem to predict quality of life after orthognathic surgery.

Abstract

Background: It was essential to evaluate respiratory function when diagnosing and planning orthodontic treatment. Based on the correlation between pharyngeal airway space and craniofacial structure, airway width was hypothesized to be an indicator of airway patency in different groups of skeletal malocclusion.

Aim: The purpose of this study was to investigate age and gender related changes in pharyngeal airway dimensions in different sagittal skeletal relationships

Materials and Method: Sixty lateral cephalograms of patients aged 10-30 years with no pharyngeal pathology or nasal obstruction were retrospectively selected and categorized into skeletal Class I (n = 20), Class II (n = 20), and Class III (n = 20) malocclusion based on ANB angle. McNamara's airway analysis was used to quantify upper- and lower-airway dimensions. The analyses of intergroup differences were performed using a one-way ANOVA, an independent t-test, and Tukey's test as a post-hoc test.

Results: Participants in the study ranged in age from 20.57 ± 5.41 years (males) and 20.03 ± 4.58 years (females) were included in the study. The upper pharyngeal airway (UPA) dimensions demonstrated a positive correlation with age. In both genders, the mean upper pharyngeal airway (UPA) size exceeded the lower pharyngeal airway (LPA) size, but neither age nor gender was associated with statistically significant differences in skeletal malocclusion.

Conclusion: It was shown that skeletal malocclusions of different types have no effect on the upper and lower pharyngeal airways and that the upper and lower pharyngeal airways are not influenced by age or gender.

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.
