Abstract

Background: The trend of studies on dental medicaments is increasing rapidly. Antibacterial or anti-inflammatory activity is most frequently studied. Ovalbumin is one of the proteins whose benefits have been studied, but these benefits are still limited because of ovalbumin's potential for proliferative bioactivity. Purpose: The aim of this study is to examine ovalbumin's potential as a woundhealing medicament through molecular docking analysis on a protein related to the extracellular signal-regulated kinases/mitogenactivated protein kinase (ERK/MAPK) signaling pathway. Methods: Ovalbumin was hydrolyzed through BIOPEP-UWM (The BIOPEPUWMâ„¢ database of bioactive peptides). Protein target and interaction were predicted using Similarity Ensemble Approach target prediction webserver, SuperPred webserver, STRING webserver, and Cytoscape version 3.9.1. Selected fragments were docked using Autodock Vina in PyRx 0.8 with Tukey's multiple comparison test and Biovia Discovery Studio version 19.1.0.18287 for visualization. Results: This study found that ovalbumin has the potential to positively regulate cell proliferation, angiogenesis, and fibroblast growth factor production. Six of the 131 fragments of ovalbumin could interact with 73 proteins, and the 20 proteins with the highest probability and score of betweenness centrality showed potential for bioactivity. Five fragments and povidone-iodine interacted inside the Adenosine triphosphate (ATP) phosphorylation site of ERK2, whereas fragment 1 (F1) and glycerin interacted outside the site. F1 could decrease the binding energy required for adenosine 5"²-[,-methylene]triphosphate or an ATP-analogue chemical compound to interact with ERK2 compared to the control, with a score that was not significant. Conclusion: Ovalbumin has the potential to induce cell proliferation by affecting ERK2-ligand interactions.

Abstract

Background: Although dental trauma has been reported at various frequencies worldwide, as far as we know there are few data regarding the frequency of dental trauma during the pandemic period. Purpose: This study aims to retrospectively evaluate the data of pediatric patients who were admitted to the Department of Pedodontics in a university hospital due to dental trauma during the COVID-19 pandemic. Methods: Between April 2020 and December 2020, the clinical records regarding admissions to the Harran University Faculty of Dentistry Pedodontics clinic due to dental trauma were examined. The age and gender of the patient, type of trauma, teeth affected by the trauma, and treatment methods applied after the trauma were recorded. The data obtained were analyzed using the independent sample t-test for intergroup comparisons and Pearson chi-square test for categorical variables with the help of Statistical Package for the Social Sciences version 23.0. Results: The data of 43 patients (27 males and 16 females) aged between 1–13 years (mean age: 9.13±3.20) who were admitted to the clinic with trauma complaints during an eight-month period were evaluated. It was determined that the most common trauma types in the pandemic period were simple crown fracture (25.6%) and subluxation/lateral luxation (23.3%). During the pandemic, 34.9% of all cases were "falling at home”, while "falling at school” was 14.0% (using the Pearson chi-square test). Conclusion: The COVID-19 pandemic period has affected many aspects of social life as well as the number of patients who were admitted for dental trauma and the causes of trauma. Multicenter studies are needed for more accurate results.

Abstract

Background: Oral cancer therapy, such as radiation or surgical treatment, has pernicious long-term effects that patients suffer throughout their life, the disability being considerable with delayed diagnosis. It is well known that many oral cancers develop from oral potentially malignant disorders (OPMDs). Patients diagnosed with OPMDs may have an increased risk of developing cancer anywhere in the oral cavity. Early detection and intervention could be essential prevention strategies to inhibit oral cancer progression. OPMDs may not immediately develop into carcinoma. However, this condition provides a "field” of specific abnormalities wherein evolving altered genetic cells can be explained with the "field cancerization” concept. Purpose: This review aims to describe the "field cancerization” concept in oral cancer and OPMD, which is expected to contribute to a better clinical management strategy for oral cancer prevention. Review: "Oral field cancerization” describes oral cancers that develop in multifocal areas of pre-cancerous changes. It can be found as histologically abnormal tissue surrounding the tumor, suggesting that oral cancer often consists of multiple independent lesions. Conclusion: The oral field cancerization concept should prompt healthcare professionals to remind their patients that frequent oral examination with histological studies and molecular testing is mandatory for those at high risk of developing malignancies.

Abstract

Background: Oral squamous cell carcinoma (OSCC) occurs in approximately 95% of people older than 40 years; usually, it is diagnosed at the age of 60 years. The etiology of OSCC is multifactorial. Chronic mechanical trauma due to sharp teeth has also been suggested as an etiology of oral squamous of the tongue. Purpose: This case report aimed to describe the etiology of OSCC resulting from mechanical trauma and to prevent further metastasis by correctly diagnosing the lesion earlier. Case: A 49-year-old female patient presented with painful and swollen stomatitis two months ago. No submandibular lymph nodes were palpable. An indurated ulceration and sharp teeth on the right region of the jaw were obtained from the intraoral examination. Malignancy was concluded from Histopathology Examination (HPE) and Magnetic Resonance Imaging (MRI) radiography results. Case Management: Multiple extractions were chosen to eliminate the etiology of mechanical trauma due to sharp teeth, and the patient underwent hemiglossectomy with the keyhole method. Postoperative, the histopathology examination revealed an OSCC of the tongue. The patient is currently in the second cycle of chemotherapy by hematologist-oncologists. Conclusion: The early appropriate diagnosis of a tongue ulcer can prevent metastasis, decrease morbidity, and increase quality of life.

Abstract

Background: Kalimantan's people consume Stenochlaena palustris leaf extract as food and for traditional medicine. The bioactive components of Stenochlaena palustris leaf extract are flavonoids, alkaloids, saponins, and tannins. An in vitro study shows that the leaf extract has no toxic effect, so it can be used as an alternative drug in oral health, such as in mouthwashes or topical ulcer drugs. Purpose: This study aims to analyze the toxic effects of Stenochlaena palustris leaf extract based on the bleeding and lesions resulting from necrosis in kidney by using histopathology examination. Methods: The Stenochlaena palustris leaves were extracted using 95% ethanol and then given to male Wistar strain (Rattus norvegicus) with a 2,000, 2,500, and 3,000 mg/kg/body weight two times a day for fourteen days. The kidneys were collected and subjected to histopathology examination. Results: There are higher bleeding and necrosis lesion rates in the 2,500 and 3,000 mg/kg/body weight of Stenochlaena palustris leaves extract group compared to the control and 2,000 mg/kg/body weight of Stenochlaena palustris leaves extract group (p<0.05). Conclusion: Stenochlaena palustris leaf extract showed no toxic effect at doses of 2,000 mg/kg/body weight.

Abstract

Background: A dentigerous cyst is the second-most frequently observed odontogenic cyst, and an ameloblastoma is one of the most frequently observed odontogenic tumors. Both are mostly associated with an impacted mandibular third molar and have similar characteristics. Diagnostic difficulties often result in misdiagnosis and remain a challenge to overcome. Comprehensive clinical, radiographic, and histopathological views are essential to correctly diagnose the problem and formulate the most suitable treatment plan. Purpose: This case report aims to present a thorough approach to the diagnostic and surgical procedures involved in treating a dentigerous cyst that resembles an ameloblastoma by using marsupialization followed by enucleation. Case: This article presents the case report of a 27-year-old male patient with an infected dentigerous cyst resembling a unicystic ameloblastoma associated with a totally impacted lower mandibular left third molar. The patient had a history of swelling, pain, and pus drainage in the retromolar area. Symptoms subsided after antibiotic and analgesic prescriptions, but the lesion remained and was slowly progressing. The diagnostic approach began with a fine-needle aspiration biopsy, and the result confirmed a benign cystic lesion that was suspected to be an odontogenic tumor. Then an incisional biopsy was conducted under local anesthesia, diagnosing an infected dentigerous cyst. Case Management: Marsupialization and decompression using an obturator was preferred, followed by enucleation. Nine months later, a radiographic examination revealed satisfactory bone regeneration without recurrence. Conclusion: An incisional biopsy plays a vital role in establishing a definitive diagnosis. Marsupialization followed by enucleation offers an excellent combination of treatments achieving complete cyst removal, anatomical structure preservation, and bone regeneration with minimal complications.

Abstract

Background: Using fixed orthodontic appliances inhibits oral hygiene, which can lead to the increased development of biofilms and Streptococcus mutans, a cariogenic bacterium that is well known for causing dental caries, derived from bacteria of the Streptococcus genus. In order to decrease biofilm and the degree of cariogenic bacteria in the oral cavity, a variety of herbal ingredients are used. Among these, mobe (Artocarpus lakoocha Buch. Ham) leaves are herbal ingredients with antibacterial properties. Purpose: This study aimed to investigate the antibacterial activity, antibiofilm, and leakage of DNA and protein from mobe leaves. Methods: The diffusion method was used to assess antibacterial activity and determine the minimum inhibitory concentration. The antibiofilm activity was evaluated with Ultraviolet–visible (UV-Vis) spectrophotometry (600 nm), using violet crystal staining. The detection of DNA and protein leakage was carried out by checking for absorbance values using the UV-Vis spectrophotometry (260 nm and 280 nm). An increase in the absorbance value in the measured cell indicated an increase in the level of cell content produced by the cell. One-way analysis of variance was used statistically analyze the results of this study (P < 0.05). Results: Mobe leaf (A. lakoocha) extract's minimum inhibitory concentration level was 3.125 mg/ml, the effective concentration of ethanol extract for inhibiting biofilm formation was 3.125 mg/ml, and the effective concentration of ethanol extract that could cause DNA and protein leakage was 50 mg/ml. Conclusions: Mobe leaf extract has good MIC for S. mutans.

Abstract

Background: Regenerative periodontal surgical therapy faces significant challenges due to the limited ability of the body to regenerate damaged periodontal tissue. One of the primary goals in regenerative periodontal therapy is regaining periodontal tissue attachment after destruction by periodontal disease. Currently, stem cells, harnessing three pivotal components”cells, biomaterials, and growth factors”are widely used in periodontal regeneration. Stem cells can be obtained from various sources, either by isolating cells from bone marrow, teeth, and muscles or through the somatic cell programming method (reprogramming) known as induced pluripotent stem cells (iPSCs). Purpose: This review aims to describe the potential use of iPSCs in the treatment of periodontal defects. Review: Search strategies were developed using the PubMed, LILACS, Scielo, and Wiley online databases during the period of 2012–2022. Ten articles met the inclusion criteria. iPSCs were obtained by inducing somatic cells from both dental and non-dental sources with factors Oct3/4, Sox2, Klf4, and c-Myc. Periodontal tissue regeneration procedures can be augmented with iPSCs. Unlike tooth-based stem cells, iPSCs offer several advantages, such as unlimited cell sources and the capability to differentiate into any cell type, including periodontal tissue. The potential of iPSCs extends to correcting periodontal bone defects and forming new periodontal tissues, such as alveolar bone, cementum, and periodontal ligament. However, iPSCs do have limitations, including the need for clinical trials, cell programming production facilities, and optimization of differentiated-cell functionality. Conclusion: The combined use of iPSCs in cell-based tissue engineering holds vast potential for future periodontal treatment strategies.

Abstract

Background: Class II discrepancies were primarily perceived as sagittal problems. Class II malocclusions usually cause aesthetic and functional problems, depending on the degree of anterior-posterior mismatch and interaction with adjacent soft tissues. Purpose: This case report aimed to evaluate the effect of modified sagittal guidance twin-block (SGTB) for Class II Skeletal and Dental Changes in a growing patient. Case: A 10-year-old patient presented with her parents and complained mainly of aesthetic problems. Diagnosis showed skeletal Class II pattern (ANB 6º) with retrognathic mandible, angle Class II molar relationship, convex facial profile, lower dental midline shift, crowding in the lower anterior teeth, and incompetent lips. Case Management: A growth modification treatment plan was considered for the patient, using modified SGTB. Both bonded and removable had the same design. In the SGTB, the bite block was angled at 70º, pushed toward the occlusal plane to maximize horizontal force toward the mandible. As a result, the mandible is guided forward and optimally positioned during occlusion. Conclusion: An ideal overjet and slight correction on lower anterior crowding teeth were achieved after full-time wear of a modified SGTB for 12 months. A modified SGTB appliance is effective in treating skeletal Class II with a retrognathic mandible.

Abstract

Background: Formalin-fixed paraffin-embedded (FFPE) specimen archives are a valuable source of sample material for molecular biological analysis. However, the DNA isolated from FFPE samples is usually low in concentration and fragmented. Thus, it is necessary to optimize the FFPE DNA extraction protocol to obtain the best results. Proteinase K incubation is undoubtedly crucial in DNA extraction procedures, but this step is often not well explained in the manufacturer's manual. Purpose: This study aimed to find the optimal duration for proteinase K incubation protocols to achieve the highest DNA yields. Methods: Fifteen paraffin blocks of Oral Squamous Cell Carcinoma (OSCC) specimens were obtained, and the cancerous areas were microdissected into smaller cuts for DNA extraction. The samples were randomly divided into three groups (n=5) and subjected to three different proteinase K incubation protocols: one-hour incubation at 56ºC as per the manufacturer's instructions (Group I), 24-hour incubation at 56ºC (Group II), and 48 hours at room temperature with an additional four hours at 56ºC (Group III). The extracted DNA was then quantified using a Nanodrop spectrophotometer. The recorded data were analyzed using ANOVA-LSD. Results: The highest DNA concentration was found in Group III (107.74 ± 41.92), which was significantly higher compared to Group II (59.46 ± 30.32) and Group I (6.46 ± 1.97) (p<0.05). Conclusion: In conclusion, modifying the duration of proteinase K incubation protocols can lead to different DNA yield results. In this study, the most optimized protocol for proteinase K incubation, resulting in the highest DNA yields, was 48 hours at room temperature with an additional four hours at 56ºC.
