RESUMO
Major advances in the knowledge about the aetiopathogenesis of aggressive periodontitis (AgP) have been achieved. An ever increasing number of scientific articles related to AgP are published every year contributing significantly to the knowledge of this unique and complex disease. AgP has been classified into localised and generalised forms based on their extent and disease progression with distinct clinical and radiological features. A classification of AgP based on severity (mild, moderate and severe) exists; however, it is not easily applicable. Therefore, studies on AgP do not categorise the disease based on severity. A disease staging index for AgP is proposed based on clinical and radiological features, as well as risk factors. Based on the presence or absence of risk factors confirmed by longitudinal studies, cases of AgP can be divided into low risk, medium risk and high risk profiles for disease progression. Clinicians can devise a broad treatment plan for their AgP cases based on this staging. More frequent recall intervals are proposed for patients at medium and high risk for disease progression. Ten cases of AgP with 10-year follow-up were used to validate the staging index by retrospectively assigning prognosis and associating it with tooth loss. The use of this staging by researchers would increase external validity of research on AgP. Long-term analysis of AgP cases are needed to validate this staging index longitudinally.

BACKGROUND: Political crisis and worsening security situation in Egypt in late 2013 resulted in Malaysian students who were pursuing their dental education in Egypt being recalled home to Malaysia. The Ministry of Higher Education in Malaysia took steps to integrate these students into public and private universities in Malaysia. METHODS: We used a questionnaire and informal interviews to learn from students returning from Egypt about their experiences transitioning from dental schools in Egypt to Malaysia. RESULTS: We discuss the challenges students faced with regards to credit transfer, pastoral care, the differences in the curriculum between the dental faculties of the two nations, and the financial implications of this disruption of their training. DISCUSSION: We live in a fragile world where similar political situations will surely arise again. The approaches used by the Malaysian government and the lessons learned from these students may help others. The perspectives of these students may help educators reintegrate expatriate students who are displaced by political instability back into the education system of their own countries.

Successful long-term management of molars having advanced periodontal disease with secondary endodontic involvement is a challenge to the periodontist. Several treatment options exist for the periodontist based upon various factors. A patient with a deep periodontal pocket on the right mandibular first molar reported for dental treatment. Periapical radiographs revealed bone loss extending to the apex of the mesial root. The treatment plan included scaling, root planing, endodontic therapy and periodontal surgery for the involved tooth. During periodontal surgery, resective and regenerative treatment options were evaluated and explained to the patient. Considering the prognosis of the case, risk-benefit ratio and the patient's choice, regenerative periodontal therapy was performed. The case has been followed for two years, with gain in clinical attachment and radibgraphic bone fill. The authors discuss factors to be considered when choosing regenerative periodontal therapy over resective periodontal therapy.

As esthetics gain importance, periodontal plastic surgical procedures involving soft tissue grafts are becoming commoner both around natural teeth as well as around implants. Periodontal soft tissue grafts are primarily used for the purpose of root coverage and in pre-prosthetic surgery to thicken a gingival site or to improve the crestal volume. Soft tissue grafts are usually harvested from the palate. Periodontal plastic surgical procedures involving soft tissue grafts harvested from the palate have two surgical sites; a recipient site and another donor site. Many patients are apprehensive about the soft tissue graft procedures, especially the creation of the second/donor surgical site in the palate. In the past decade, newer techniques and products have emerged which provide an option for the periodontist/patient to avoid the second surgical site. MucoMatrixX, Alloderm(®), Platelet rich fibrin, Puros(®) Dermis and Mucograft(®) are the various options available to the practicing periodontist to avoid the second surgical site. Use of these soft tissue allografts in an apprehensive patient would decrease patient morbidity and increase patient's acceptance towards periodontal plastic surgical procedures.

AIM: To report rare findings of oral and periodontal manifestations in a patient with Epidermal nevus syndrome (ENS). BACKGROUND: The ENS describes the rare association of an epidermal nevus with abnormalities of central nervous system,ocular and skeletal abnormalities. Reports of oral involvement have been few. Also, most of the intraoral lesions have been reported in patients with nevi that do not fulfill the criteria for the diagnosis of ENS. CASE DESCRIPTION: This report describes a case of ENS that, in addition to cutaneous manifestations showed skeletal involvement and intraoral manifestations such as the extension of the nevi on the face intraorally involving the labial mucosa, hypoplasia, hypodontia of teeth and severe periodontal destruction. CONCLUSION: Patients with extensive epidermal nevi and systemic abnormalities should be suspected of having the ENS. Evaluation and management of patients with ENS requires a multidisciplinary team approach involving the dermatologist, pediatrician, ophthalmologist, neurologist, genetist, plastic surgeon and orthopedic services. Although uncommonly described in association with ENS, significant intraoral lesions do occur. Periodontal manifestations as in our patient, which to our knowledge has not been described in association with ENS so far, may also be present. CLINICAL RELEVANCE: Alteration of the response of periodontal tissues to dental plaque in the presence of certain systemic diseases has been reported, but not in association with ENS. Severe periodontal destruction due to exaggerated response to dental plaque was seen in the present case. Hence, emphasis on oral hygiene maintenance in such patients is essential. Patients with ENS must be evaluated periodically as they show a persistent predisposition for the development of tumors.

BACKGROUND: An invasive dental procedure is considered one of the risk factors for osteonecrosis of the jaw, especially among patients on bisphosphonates. This study aimed to determine the awareness and perceptions of medical practitioners regarding bisphosphonate-related osteonecrosis of the jaw (BRONJ), and their attitude towards dental referrals of such patients. METHODS: This cross-sectional questionnaire-based study was conducted among medical practitioners in and around Mysore city, Karnataka, India, who commonly prescribe bisphosphonates. The sample included orthopaedic doctors, physicians, endocrinologists, and oncologists, divided based on the duration of practice and speciality. Data on the type of practice, awareness of BRONJ, referral to a dentist before/during therapy, and patient education about adverse effects, were collected and analyzed. A p-value ≤0.05 was considered statistically significant. RESULTS: Among 58 practitioners, 84.5% (49) were aware of the association between bisphosphonates and BRONJ, while 56.9% (33/58) believed dental procedure to be a risk factor, and 55.2% (32/58) did not recommend screening of the oral cavity by a dentist before initiation of bisphosphonate therapy. A majority (65.5%) of them educated their patients about adverse effects. Mean knowledge scores varied with specialization (post-graduation vs. super specialization = 1.43 vs. 2; p = 0.01) but not with the duration of practice (<= 10 years vs. >10 years= 1.57 vs. 1.4; p= 0.24). CONCLUSION: The practitioners in our study were oblivious to dental procedures' role in the osteonecrosis of the jaw, highlighting the need for continuing education programs regarding BRONJ for medical and dental professionals. Clinicians updated regarding evidence-based practices and working cooperatively in teams may reduce the incidence of medication-related osteonecrosis of the jaw.

The majority of current biofilm models or substrates are two-dimensional (2D) and support biofilm growth in the horizontal plane only. Three-dimensional (3D) substrates may support both horizontal and vertical biofilm growth. This study compared biofilm growth quantity and quality between highly porous 3D micrometric fibrous scaffolds and 2D film substrates fabricated from medical grade polycaprolactone (mPCL). Melt electrowriting (MEW), a high-resolution additive manufacturing technology, was employed to design orderly aligned fine (~12 µm) fibre-based 3D scaffolds, while 2D films were fabricated by a casting method. The 3D scaffolds with a controlled pore size of 100 and 250 µm and thickness of ~0.8 mm and 2D films were incubated in pooled saliva collected from six volunteers for 1, 2, 4, 7 and 10 days at 37 °C to facilitate polymicrobial biofilm formation. Crystal violet assay demonstrated greater biofilm biomass in 3D MEW scaffolds than in 2D films. Biofilm thickness in 3D scaffolds was significantly higher compared to the biofilm thickness in 2D films. Both biovolume and substratum coverage of the biofilms was higher in the 3D scaffolds compared to 2D films. Polymeric bridges, pores, and channels characteristic of biofilms could be demonstrated by scanning electron microscopy. 16S rRNA sequencing demonstrated that the polymicrobial biofilms in the 3D scaffolds were able to retain 60-70 % of the original inoculum microbiome after 4 days. The MEW-fabricated 3D fibrous scaffold is a promising substrate for supporting multidirectional biofilm growth and modelling of a polymicrobial microcosm.

BACKGROUND: This prospective cohort study aimed to evaluate the antibody responses in non-invasive gingival crevicular fluid (GCF) and unstimulated whole saliva to the SARS-CoV-2 Spike unit 1 receptor-binding domain (S1-RBD) protein following administration of the mRNA BNT162b2 vaccine. METHODS: This longitudinal study recruited 37 participants with no prior COVID-19 exposure (eight people recruited prior to the COVID-19 pandemic - labeled pre-COVID, 16 vaccinated and 13 non-vaccinated participants). An enzyme-linked immunosorbent assay (ELISA) was used to determine antibody levels against S1-RBD in saliva (n=90) and GCF (n=80) samples obtained at 1 and 3 weeks after dose 1, and 3 days, 7 days, and 3 weeks after dose 2. To determine previous SARS-CoV-2 infection status, anti-nucleocapsid (N) Ig levels were determined in samples from the pre-COVID (saliva as reference), non-vaccinated (saliva and GCF), and vaccinated (saliva and GCF) participants at 1-week post-dose 1 using ELISA. RESULTS: Salivary levels of anti-N antibodies measured in samples from vaccinated and nonvaccinated participants were comparable to those in pre-COVID saliva samples collected between October 2018 and September 2019, thus confirming that all study participants had no prior SARS-CoV-2 infection. Overall, the levels of anti-S1-RBD antibodies peaked at 3 weeks after dose 2 in both saliva and GCF for all three immunoglobulin isotypes. Notably, the concentration of anti-S1-RBD antibodies in GCF was significantly higher than in saliva at all time points. CONCLUSION: This study establishes GCF and saliva as viable alternative non-invasive sources to monitor levels of antibodies following vaccination, with GCF demonstrating feasibility as a biofluid source for the detection of antibodies against SARS-CoV-2 S1-RBD antigen.

Oral biofilms are three-dimensional (3D) complex entities initiating dental diseases and have been evaluated extensively in the scientific literature using several biofilm models and assessment techniques. The list of biofilm models and assessment techniques may overwhelm a novice biofilm researcher. This narrative review aims to summarize the existing literature on biofilm models and assessment techniques, providing additional information on selecting an appropriate model and corresponding assessment techniques, which may be useful as a guide to the beginner biofilm investigator and as a refresher to experienced researchers. The review addresses previously established 2D models, outlining their advantages and limitations based on the growth environment, availability of nutrients, and the number of bacterial species, while also exploring novel 3D biofilm models. The growth of biofilms on clinically relevant 3D models, particularly melt electrowritten fibrous scaffolds, is discussed with a specific focus that has not been previously reported. Relevant studies on validated oral microcosm models that have recently gaining prominence are summarized. The review analyses the advantages and limitations of biofilm assessment methods, including colony forming unit culture, crystal violet, 2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide inner salt assays, confocal microscopy, fluorescence in situ hybridization, scanning electron microscopy, quantitative polymerase chain reaction, and next-generation sequencing. The use of more complex models with advanced assessment methodologies, subject to the availability of equipment/facilities, may help in developing clinically relevant biofilms and answering appropriate research questions.

BACKGROUND: The aim of this study was to investigate an in vitro dynamic bioreactor model by evaluating the antimicrobial effect of clinically relevant amoxicillin doses on polymicrobial microcosm biofilms derived from subgingival plaque. METHODS: Biofilms from pooled subgingival plaque were grown for 108 hours in control and experimental dynamic biofilm reactors. Amoxicillin was subsequently infused into the experimental reactor to simulate the pharmacokinetic profile of a standard 500 mg thrice-daily dosing regimen over 5 days and biofilms were assessed by live/dead staining, scanning electron microscopy, and quantitative polymerase chain reaction. RESULTS: Following establishment of the oral microcosm biofilms, confocal imaging analysis showed a significant increase in dead bacteria at 8 hours (p = 0.0095), 48 hours (p = 0.0070), 96 hours (p = 0.0140), and 120 hours (p < 0.0001) in the amoxicillin-treated biofilms compared to the control biofilms. Nevertheless, viable bacteria remained in the center of the biofilm at all timepoints. Significant reductions/elimination in Campylobacter rectus, Tannerella forsythia, Aggregatibacter actinomycetemcomitans, and Peptostreptococcus anaerobius was observed among the amoxicillin-treated biofilms at the 96 and 120 hour timepoints. CONCLUSION: A novel in vitro dynamic model of oral microcosm biofilms was effective in modeling the antimicrobial effect of a pharmacokinetically simulated clinically relevant dose of amoxicillin.
RESUMO
UNLABELLED: This case report describes the management of an 18-year-old female who presented with generalized aggressive periodontitis, gingival enlargement and a mesiodens. Diagnosis for aggressive periodontitis was determined based on history, clinical findings and radiographic examination. Treatment included oral prophylaxis, extraction of the mesiodens and elimination of infectious microorganisms, using a combination of surgical intervention and antimicrobial therapy with long-term maintenance. CLINICAL RELEVANCE: Presence of gingival enlargement in cases of aggressive periodontitis may be clinically confusing; hence, the diagnosis should always be based on the patient's history as well as the clinical and radiographic findings.

Numerous in vitro studies highlight the role of quorum sensing in the pathogenicity and virulence of biofilms. This narrative review discusses general principles in quorum sensing, including Gram-positive and Gram-negative models and the influence of flow, before focusing on quorum sensing and quorum quenching in cariogenic and periodontopathic biofilms. In cariology, quorum sensing centres on the role of Streptococcus mutans, and to a lesser extent Candida albicans, while Fusobacterium nucleatum and the red complex pathogens form the basis of the majority of the quorum sensing research on periodontopathic biofilms. Recent research highlights developments in quorum quenching, also known as quorum sensing inhibition, as a potential antimicrobial tool to attenuate the pathogenicity of oral biofilms by the inhibition of bacterial signalling networks. Quorum quenchers may be synthetic or derived from plant or bacterial products, or human saliva. Furthermore, biofilm inhibition by coating quorum sensing inhibitors on dental implant surfaces provides another potential application of quorum quenching technologies in dentistry. While the body of predominantly in vitro research presented here is steadily growing, the clinical value of quorum sensing inhibitors against in vivo oral polymicrobial biofilms needs to be ascertained.
RESUMO
This study evaluated the effect of alloplastic bone grafts in osseous defects following surgical removal of horizontally impacted third molars by comparing the periodontal measures distal to the second molar in grafted and nongrafted third molar extraction sites. Materials and Methods: A double-blind, randomized, controlled clinical trial was designed on subjects with bilateral horizontally impacted mandibular third molars. Grafting consisting of alloplasts at the third molar extraction sites was compared with nongrafted sites. This study assessed 54 randomized sites in 27 patients who were selected using a split-mouth design. The predictor variable included the change in pocket depth distal to the mandibular second molar and associated dentin hypersensitivity around the second molar, assessed preoperatively and at 3 and 6 months after third molar surgery. The data regarding pocket depth reduction was statistically analyzed using paired t-test. The data concerning reduction in dentin hypersensitivity was statistically analyzed using chi-square test. Results: Six months after third molar surgery, mean pocket depth distal to mandibular second molar decreased significantly at the grafted sites compared to the nongrafted sites. The reduction in dentin hypersensitivity of mandibular second molar was statistically significant for the grafted sites at 6 months, compared to the nongrafted sites.

Shisha is a centuries-old traditional smoking habit rapidly gaining popularity among the students and young adults in Malaysia. The present study evaluated secondhand smoke exposure (SHS) and characteristics of 25 indoor and 25 outdoor shisha centers (SC) operating around the educational institutes such as universities in Petaling Jaya, Malaysia. We observed a significantly higher particulate matter (PM)2.5 concentration in indoor than outdoor SC (3595.28 µg/m3 and 65.12 µg/m3, p < 0.001, respectively). SCs are offering different flavors to attract clients and exposing students and young professionals to a significantly high concentration of SHS. Such exposures may pose a serious health risk. Therefore, policymakers need to strengthen tobacco guidelines and eliminate loopholes in the sale of shisha by enforcing comprehensive and strict smoke-free laws.

Sensitive detection of immunoglobulin antibodies against SARS-CoV-2 during the COVID-19 pandemic is critical to monitor the adaptive immune response after BNT162b2 mRNA vaccination. Currently employed binding antibody detection tests using 2D microplate-based enzyme-linked immunosorbent assays (ELISA) are limited by the degree of sensitivity. In this study, a 3D antibody test was developed by immobilizing the receptor-binding domain on Spike subunit 1 (S1-RBD) of SARS-CoV-2 onto engineered melt electrowritten (MEW) poly(ε-caprolactone) (PCL) scaffolds (pore: 500 µm, fiber diameter: 17 µm) using carbodiimide crosslinker chemistry. Protein immobilization was confirmed using X-ray photoelectron spectroscopy (XPS) by the presence of peaks corresponding with nitrogen. Self-developed indirect ELISA was performed to assess the functionality of the 3D platform in comparison with a standard 2D tissue culture plate (TCP) system, using whole unstimulated saliva samples from 14 non-vaccinated and 20 vaccinated participants (1- and 3- weeks post-dose 1; 3 days, 1 week and 3 weeks post-dose 2) without prior SARS-CoV-2 infection. The three-dimensional S1-RBD PCL scaffolds, while demonstrating a kinetic trend comparable to 2D TCP, exhibited significantly higher sensitivity and detection levels for all three immunoglobulins assayed (IgG, IgM, and IgA). These novel findings highlight the potential of MEW PCL constructs in the development of improved low-cost, point-of-care, and self-assessing diagnostic platforms for the detection and monitoring of SARS-CoV-2 antibodies.
RESUMO
Zinc (Zn) has recently been identified as an auspicious biodegradable metal for medical implants and devices due to its tunable mechanical properties and good biocompatibility. However, the slow corrosion rate of Zn in a physiological environment does not meet the requirements for biodegradable implants, hindering its clinical translation. The present study aimed to accelerate the corrosion rate of pure Zn by utilizing acid etching to roughen the surface and increase the substrate surface area. The effects of acid etching on surface morphology, surface roughness, tensile properties, hardness, electrochemical corrosion and degradation behavior, cytocompatibility, direct cell attachment, and biofilm formation were investigated. Interestingly, acid-treated Zn showed an exceptionally high rate of corrosion (â¼226-125 µm/year) compared to untreated Zn (â¼62 µm/year), attributed to the increased surface roughness (Ra â¼ 1.12 µm) of acid-etched samples. Immersion tests in Hank's solution revealed that acid etching accelerated the degradation rate of Zn samples. In vitro, MC3T3-E1 cell lines in 50 and 25% conditioned media extracts of treated samples showed good cytocompatibility. Reduced bacterial adhesion, biofilm formation, and dispersion were observed for Staphylococci aureus biofilms cultured on acid-etched pure Zn substrates. These results suggest that the surface modification of biodegradable pure Zn metals by acid etching markedly increases the translation potential of zinc for various biomedical applications.

The authors report a case of a 16-year-old male with peripheral odontogenic fibroma (POF) in the anterior maxilla associated with dilaceration of a tooth in its vicinity. A solitary, exophytic and sessile growth was present between the maxillary right central and lateral incisors and extended from the labial mucosa to the palatal gingiva. A periapical radiograph of the maxillary right central incisor revealed a shortened and dilacerated root. The growth was excised and sent for histopathologic examination. A diagnosis of POF (World Health Organization type) was rendered. The clinical and microscopic features are discussed.

Peripheral ossifying fibroma (POF) is a common solitary gingival overgrowth thought to arise from the gingival corium, periosteum, and periodontal ligament. Commonly used synonyms for POF include calcifying fibroblastic granuloma, peripheral fibroma with calcification, peripheral cementifying fibroma, and calcifying or ossifying fibrous epulis. Because it is possible to misdiagnose POF as pyogenic granuloma, peripheral giant cell granuloma, or odontogenic tumors, histopathological examination is, therefore, essential for accurate diagnosis, and differential diagnosis is important because of POF's tendency to recur. This article presents a case of peripheral ossifying fibroma in a 15-year-old female along with the clinical, histopathologic, and radiographic features and treatment details.

The periodontal pocket, one of the definitive signs of periodontal disease, is the most common parameter to be assessed by dental clinicians. Periodontal probes have been the instruments most commonly used to locate and measure these pockets. Regular use of periodontal probes in routine dental practice facilitates and increases the accuracy of the process of diagnosing the condition, formulating the treatment, and predicting the outcome of therapy. Advances in the field of periodontal probing have led to the development of probes that may help reduce errors in determining this parameter used to define the state of active periodontal disease. One such advance is the emergence of probes that purportedly assess periodontal disease activity noninvasively. The selection of periodontal probe depends on the type of dental practice: a general dental practitioner would require first- or second-generation probes, while third- through fifth-generation probes generally are used in academic and research institutions as well as specialty practices.
