A New Growth Prediction Method Involving Maxillofacial Hard and Soft Tissue Calibrations- A Radiological Analysis

2024-06-02T09:17:38+0530

OBJECTIVE: Growth prediction is of key importance in pediatric patients as well as growing individuals opting for orthodontic or orthopedic treatment. The objective of this study is to assess a new growth prediction method involving maxillofacial hard and soft tissue calibrations. Orthodontic treatment is most favourable and effective during pubertal growth and hence growth assessment and prediction are significant in planning treatment for dental and maxillofacial abnormalities. It can also be helpful in diagnosis of various growth disorders in pediatric patients.

MATERIAL AND METHOD: The sample comprises of standardized lateral cephalometric radiograph with the size of 100 subjects including male and female of 8-16 years of age who visited Department of Orthodontics and Dentofacial Orthopedics. All cephalometric radiographs were taken and the chosen hard and soft tissue calibrations like ramus length and nasolabial angle and CVM staging were evaluated and correlated using One-way ANOVA and Spearman correlation.

RESULT: CVM staging showed positive correlation with ramus length and age but no correlation with nasolabial angle. One-way ANOVA showed highly significant correlation of age, NLA and RL values between different CVM stages and Spearman correlation showed highly significant correlation of CVM with age, NLA and RL

CONCLUSION: Growth can also be predicted from ramus length and age of the patient as the study shows positive correlation between CVM staging and ramus length but no correlation with nasolabial angle. The calibrations are correlated to each other as cvm directly proportional to ramus length and age and inversely proportional to nasolabial angle.

“Development and Validation of Professionalism, Perception, Fear, and Anxiety Assessment Scale of Dental Students about Dentistry After Outburst of Covid-19 And Its Variant.”

2024-06-02T09:17:38+0530

Introduction:

The rapidly spreading COVID-19 via respiratory droplets and aerosol made dentists treat only emergencies during this period as they deal with most of the aerosol-generating procedures. Not only day-to-day practice but even the education system has also been affected, leading to a new educational system through online teaching and learning.

Methodology: The study was divided into three phases: first, item tool development using Focus Group Discussion; second, content and face validation by a panel of experts; and third, psychometric testing (internal consistency, stability, and construct validity).

Results: The faculty Focus Group Discussion (FGD)produced three scale domains, whereas the dentistry students' FGD yielded 28 items. A group of experts certified the tools' content using LAWSHE's Scale. Two items were eliminated due to the content analysis, with a (CVR) critical of < 0.538. Using factor analysis, the researchers discovered many subscales in each domain: Professionalism: Empathy and Humanism, and Responsibility: Perception: for learning and clinical training, academic and social self-perceptions, and perceived infectability, as well as Covid-19 Phobia in Fear and Anxiety. It has a high level of internal consistency, as seen by the overall Cronbach's coefficient values. The content, face, construct validity, and retest reliability of the three domains of the instrument, as well as its subscales, were all found to be relatively stable.

Conclusion: The new tool was found to be valid and trustworthy. It may be used to evaluate dental students in both undergraduate and postgraduate programs in various institutions Pan India and different Countries.

Purpose: The objective of this study was to evaluate and compare the microleakage in Zirconia crowns cemented with Bioactive, Conventional GIC, and Dual Cure Resin Luting Cements.

Materials and Methods: 45 Freshly extracted permanent molars were randomly equally divided. Group 1- Bioactive Cement, Group 2: Conventional GIC and Group 3: Dual Cure Resin Cement. Teeth were embedded in resin blocks 1 mm cervical to CEJ and prepared according to the standardized protocols, zirconia crowns were fabricated using CAD CAM technology and cemented onto the respective tooth preparations according to the manufactures instructions and excess cement was removed. After cementation all restored teeth were placed in buffered saline solution at 37 degrees centigrade for 1 day. Samples of each group were divided into 3 subgroups i.e. A, B and C, (5 samples each) and for aging subgroup B and C of all groups were placed in a thermocycler for 6000 and 10,000 cycles alternating between 5 degrees centigrade and 55 degrees centigrade to simulate aging at 6 months and 12 months respectively. All samples were painted with acrylic varnish to within 1 mm of crown margin and were placed in 2 % basic fuchsin dye solution. After 24 hrs. they were sectioned buccolingually, and were examined under a stereomicroscope at 30 X magnification for microleakage and scored.

Results: Based on results obtained by statistical analysis of the readings recorded from stereomicroscope for microleakage it was concluded that the microleakage score of group 1 samples was significantly less than that of samples in group 2 (p value-0.001*) and in group 3 (p value-0.007*). There was no significant difference in the microleakage score of groups 2 and 3 samples (p value-0.061).

Conclusions: The research revealed that the Bioactive luting agent exhibited lower microleakage than Conventional GIC, and Dual Cure Resin Luting Cement. Therefore, the null hypothesis was rejected.

Comparison of Dentoskeletal Changes In Skeletal Class II Malocclusion Using two Different Fixed Functional Appliances: A 2 Case Report

2024-06-02T09:17:38+0530

Introduction: Class II malocclusion refers to an anteroposterior discrepancy that could be characterized by a dentoalveolar and/or skeletal involvement. When skeletal involvement is present, mandibular retrusion is the primary etiological factor. Several methods have been proposed for treatment of this malocclusion and their choice would depend on the degree of dentoalveolar or skeletal involvement, patient growth pattern, age, cooperation and main complaint. Fixed functional appliances are an excellent option in patients with growth potential. These appliances have the advantage of not depending on patient compliance, which may be related to more predictability. Aim: This article presents 2 case reports that compare the dentoskeletal changes of patients diagnosed with skeletal class II treated with Forsus fatigue resistant device (FFRD) and Powerscope class II corrector (PS). Conclusion: Power Scope Class II corrector and Forsus fatigue resistant device (FFRD) are promising appliances that is relatively simple to install and easy to maintain by patients this directly helps the orthodontist in maintaining patient compliance to achieve the predicted treatment outcome.

Surgical obturator to rehab patient with hemimaxillectomy-a case report

2024-06-02T09:17:38+0530

Congenital malformation, trauma and surgical treatment of benign or malignant neoplasms create maxillary defects. The size and location of the defects play an important role about the degree of impairment and difficulty in prosthetic rehabilitation. Maxillectomy patients suffer from lack of support, retention, and stability of prosthesis. An obturator is a prosthesis used to close a palatal defect in a dentate or edentulous mouth. The surgical maxillary obturator prosthesis helps in the restoration of normal speech and eating habits of the patient. It also prevents the soft tissue collapse on the affected side. Thus, the facial symmetry will be preserved. It also helps to retain the space for future interim and definitive prostheses. Thus, it improves the mental well-being of the patient considerably. This clinical report describes the prosthetic rehabilitation of a maxillary defects with a surgical obturator which was given immediately following surgery.

palatal obturator - a case report

2024-06-02T09:17:37+0530

Maxillary jaw abnormalities can be traumatic, acquired, congenital, developmental, or surgical, and they can have an impact on the mouth cavity and nearby anatomical tissues. If the soft palate and/or hard palate are lost whole or partially, the remaining tissues will have an inadequate structure or will no longer function as they once did. Defects can lead to nasal reflux during deglutition and influence speech production by affecting articulation and airflow. This study aims to explore postoperative oroantral or oral-nasal communication for patients who underwent partial maxillectomy and received prosthetic rehabilitation. The complete denture was fabricated with an extension into the defect. As a result, this permanent prosthesis improved the patient's masticatory function, speech clarity, and general quality of life.

The disease is characterized by premature synostosis of coronal and sagittal sutures which begins in the first year of life. It occurs in approximately 1 in 25,000 births worldwide. Here, we report a case of this rare entity. The patient presented with brachycephaly, maxillary hypoplasia, exophthalmos, and mandibular prognathism along with dental and orbital abnormalities.

PRF dressing as a boon for FGG donor site; a clinico-histopathologic case report.

2024-06-22T08:01:45+0530

Aims and objectives: FGG is a widely used mucogingival surgery for gingival recession, but it has some disadvantages such as longer healing time and painful donor site. Reduction of this discomfort is possible by using an autologous biomaterial,PRF. The objectives of this study are to describe the favourable effects of PRF on the recovery of FGG donor sites and to compare the donor site’s healing with or without PRF.

Materials and methods: Two systemically healthy 19-year-old female patients who needed gingival augmentation were included in study. Procedure was carried out involving the palate as donor sites, wherein one patient’s donor site was allowed to heal conventionally and the other site was coated with PRF membrane to analyse differences in healing process.

Results: The results showed better and faster healing along with significantly reduced post operative pain of the PRF donor site as compare to the conventional site.

Conclusion: By accelerating the healing process, reducing patient suffering, and addressing one of the key concerns associated with the use of this treatment, this case study demonstrates PRF is an effective method in FGG patients.

Full Mouth Rehabilitation in visually impaired children with modified behaviour management techniques: A Case Series

2024-06-02T09:17:37+0530

The prevalence of childhood blindness is 0.3 per 1,000 children in industrialized countries, 1.2 per 1,000 children in developing countries, and 1.7 per 1,000 children in India. In children with visual impairment, there are limitations to moving around in different surroundings and performing basic activities, due to which managing them becomes a challenging task for Paediatric Dentists. Therefore, there is a need to train the visually impaired child with the aid of customized behaviour management techniques, so that the outcome of the treatment can be optimized. ‘Audio-Tactile Performance technique’ (ATP) is a multisensory health education method, specially designed for training visually impaired children. The ‘Tell-feel-do’ and ‘Tell-Hear-Do’ techniques can be used instead of ‘Tell-show-do’ to acquaint the patient with the relevant procedures before actual execution. This case series aims to demonstrate successful full mouth rehabilitation in children with visual impairment, using these modified behaviour management techniques.

Veneers: A Perfect Solution to Imperfect Teeth

2024-06-02T09:17:38+0530

Porcelain laminate veneer is one of the most conservative and aesthetically pleasing methods we may use to restore the human dentition and enhance the appearance of an anterior tooth. In 1928, C.L. Pincus introduced the Hollywood Veneer. He used thin porcelain veneers to make movie stars teeth more aesthetically pleasing. Over the past few decades, laminate veneers have developed into one of the most widely used restorative procedures in esthetic dentistry. They are considered as the primary option to enhance the esthetics of anterior teeth and consequently quality of life. This purpose of this article is to review the literature and highlight crucial factors for the long-term effectiveness of porcelain veneers, including case selection, tooth preparation, provisionalization, cementation, and patient maintenance.

Biomimetic And Regenerative Considerations In Endodontics: A Review

2024-06-02T09:17:37+0530

Biomimetics, literally means to mimic or copy what is life-like from nature. Biomimetics provides a new technique for improving our understanding of natural designs and functions, as well as new promising paths for mimicking natural processes. The first part of biomimetic dentistry is the restoration of destroyed or degenerated dental tissue, resulting in the full restoration of both functionality and appearance to the tooth. Additionally, the material utilized can repair, reproduce, or simulate missing dental tissue. This concept is very wide and has been applied in dental materials, for the regeneration of lost dental tissue from the stem cells. Regeneration approach is a form of biomimetics that promotes for the restoration of damaged tissue using tissue technology rather than the conventional method. The purpose of this review is to increase our understanding of biomimetics and regeneration factors related to lost tooth tissue in the field of endodontics.

2024-06-02T09:17:37+0530

Title: “Digital Workflow in Maxillofacial Prosthodontics: An Insight”

ABSTRACT

From its inception to now dentistry has made its way covering great milestones in terms of invention and precision to provide us with better working conditions and increased comfort for both clinicians and patients. To add up, is the remarkable innovation: CAD-CAM technology, which allow the dentists to provide a better and quality care to their patients. While restoring a facial defect the prosthesis should ideally be customized to put back the anatomy as accurately as possible. This process is difficult and time consuming & demands a high level of artistic skill to form a mirror image & achieve a good aesthetic match. The present time evolution of CAD/CAM is focused on methodical and swift integration and automation of the elements of design and manufacturing along with the development of new algorithms. This article reviews the development and availability of various digital technologies for the designing and manufacturing of different maxillofacial prostheses.

Periodontal Microbiology: The Emergence

2024-06-02T09:17:38+0530

There has been an undeniable relationship between microorganisms and the human body, both in terms of health and disease. One such genre is periodontal microbiology and diseases. The aetiology of a disease refers to the causal trigger(s), whereas pathogenesis refers to the mechanism(s) through which the illness advances. Periodontitis has a microbiological aetiology and an inflammatory pathophysiology, although the coordination of the contributing variables for the disease's onset and course may differ from an epidemiological standpoint (1). There has been extensive research on this disease and most of them pointed out the relationship between an unbalanced oral flora and the disease itself. Many newer technologies have helped elaborate the microbiome, from identifying native and novel bacteria to theories explaining how disturbance of oral phylogeny can lead to precipitation of this disease and paradigms based on which different treatments have been formulated. This review of pertinent literature online and offline was conducted, and data and information were then extracted, modified, and arranged under the appropriate headings. The monograph tries to compile the primitive concepts, the eventual shift of paradigms, the latest advances in treatment modalities and futuristic expectations. From a simpler PCR to new generation sequencing, this manuscript covers it all.

Internally weighted denture for management of severely resorbed mandibular ridges : A case report.

2024-06-02T09:17:38+0530

Rehabilitation of patients with severely resorbed mandibular ridges can be a clinical challenge where implants could not be a treatment of choice. Weighted mandibular dentures have been one of the treatment modality for the management of severely resorbed mandibular ridges. However in cases where the supporting edentulous alveolar mucosa is not appropriate for loading with a cast metal base, an internally weighted mandibular denture can be used. This article reports a case of severely resorbed mandibular ridge for which an internally weighted mandibular denture was fabricated with a customized weighted metal base using plaster index of the tooth arrangement as a guide. It is one of the non-invasive treatment option which provide stability, retention and function without altering the aesthetics of the denture.

Indirect sinus lift without graft placement and with immediate implant placement - a systematic review

2024-06-21T12:30:53+0530

Background: Due to persistent ridge resorption and maxillary sinus pneumatization, the maxillary posterior region has historically been difficult to implant in. To overcome these challenges various techniques have been developed. Among which sinus lift procedures; either direct or indirect are most commonly used. This systematic review investigates the success of immediate implant placement combined with indirect sinus lift without grafting in the maxillary posterior region. Specifically, it evaluates the rates of implant survival and endosinus bone formation.

Aim: To review the literature on indirect sinus lift without graft placement and with immediate implant placement following the PRISMA Guidelines.

Methodology: A systematic search was conducted on two electronic databases, PubMed and Cochrane Central, for studies published between 2010–2020. The search terms included "sinus augmentation," "sinus lift," "sinus elevation," and "indirect technique." The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed for data collection.

Results: In the initial search, 1361 articles in total were located. A total of 20 papers were chosen for full text review after duplicates were removed and titles and abstracts were screened. In this systematic review, 8 articles were chosen; 12 publications were rejected for a variety of reasons.

Conclusion: The studies included in this review evaluated the efficacy of indirect sinus elevation without grafting material, combined with immediate implant placement, for augmenting bone volume in the maxillary posterior region. All studies reported evidence of endosseous bone formation, with implant survival rates ranging from 90% to 100%.
