Abstract
Objective: This article reports the case of a patient with oral manifestation of coronavirus disease 2019 (COVID-19) treated with photobiomodulation (PBM) and photodynamic therapy (PDT). Background: Some dermatological and oral mucosal lesions have recently been linked to severe acute respiratory syndrome coronavirus 2 infection. Methods: A 65-year-old female patient with a confirmed real-time reverse transcriptase-polymerase chain reaction diagnosis of COVID-19 presented with dry edematous lips, edema with mucosal desquamation, ulceration and blood crust on the inner aspect of the lips, gingival petechiae and erythematous and pseudomembranous lesions on the dorsum of the tongue. The treatment protocol was three sessions of antimicrobial PDT (aPDT) (660 nm diode laser + methylene blue) to the lips and tongue, every 24 h to control contamination, followed by PBM (low-power laser, 100 mW, 2 J/point) to the lips, tongue, and oral mucosa for additional four sessions every 24 h. Results: Therapy association promoted pain control and healing of oral mucosal lesions in 7 days of treatment. Conclusions: PBM and aPDT could be an interesting approach to manage COVID-19 patients.

Abstract
Photodynamic therapy (PDT) is a promising approach for the healing of ulcerative lesions. This study aimed to investigate the effect of PDT using indocyanine green (ICG) in the healing of the experimentally induced oral mucosal traumatic ulcer in rat. Sixty adult male Sprague-Dawley rats were recruited in this experimental study. The ulceration was surgically made in the left cheek mucosa, and the rats were randomly assigned into four equal groups (n = 15). Oral ulcers in groups 1 and 2 were treated with the sterile saline solution (0.9%) and ICG (1 mg/ml). In group 3, laser irradiation was applied using the 810 nm diode laser in the continuous-wave mode for 30 s (light dose: 55 J/cm2, power: 300 mW, spot size: 4.5 mm). Following the topical application of ICG (1 mg/ml) in group 4, laser irradiation was performed in the same way as the previous group. After 24 h, treatments were repeated once more in all groups. The healing process was histopathologically assessed at the 3rd, 7th, and 14th days after ulceration. Wound healing was significantly accelerated in the ICG-mediated PDT group in comparison to the control group at all sampling time points (p < 0.005). However, the other groups displayed a similar healing rate (p > 0.05). Data suggest that ICG-mediated PDT has the potential to accelerate wound healing and prevent clinical infection in oral mucosal traumatic ulcers. However, further studies are required to confirm whether our results can be generalized to other wounds.

Abstract
OBJECTIVES Various therapeutic approaches, including stem-cell-based strategies and tissue engineering, have been proposed for oral ulcerative lesions. We investigated the effects of adipose tissue-derived stem cells (ADSCs) seeded onto the curcumin-loaded collagen scaffold in the mucosal healing of oral ulcers in rats. MATERIALS AND METHODS The current experimental study was conducted on 40 male Sprague-Dawley rats. Oral ulcers were created over both sides of buccal mucosa, and the rats were randomly divided into four equal groups: 1) an untreated group (negative control); 2) Teriadent-treated group (positive control); 3) group treated with curcumin-loaded collagen scaffold; and 4) group received the ADSCs (3 × 106 cells) seeded onto the curcumin-loaded collagen scaffold. Rats were sacrificed on 3rd and 7th day after ulceration for histopathological examination as well as measurement of tissue levels of myeloperoxidase (MPO), superoxide dismutase (SOD), and Interleukin-1 beta (IL-1β) activity. RESULTS Compared with the negative control, the tissue levels of MPO and IL-1β were significantly decreased in all treated groups (P<0.0001); however, the SOD activity was elevated (P<0.0001). The highest SOD activity as well as the lowest MPO and IL-1β levels were observed in the ADSCs-curcumin-loaded collagen scaffold group. The ulcer healing process at 3rd and 7th day follow-up was much more progressed in the ADSCs-curcumin-loaded collagen scaffold group in comparison with the untreated group (P=0.037 and P=0.004, respectively). CONCLUSION According to the findings of this study, ADSCs seeded onto the curcumin-loaded collagen scaffold seems to have a promising potential for oral ulcer healing applications.

Abstract
BACKGROUND Photodynamic antimicrobial chemotherapy (PACT) is a promising modality for eradication of microorganisms from the wound. This study aimed to investigate the effectiveness of PACT using indocyanine green (ICG) for reduction of bacterial load of oral ulcers in rats and its impact on the healing process. METHODS In this experimental study, 50 adult male Sprague Dawley rats were recruited. Oral ulcers were surgically made on the left cheek mucosa, and animals were randomly assigned into five groups (n = 10). Wound site in groups 1, 2, and 3 was irrigated with the sterile saline (0.9%), chlorhexidine (CHX; 0.2%), and ICG solutions (1 mg/mL), respectively. Group 4 was exposed to laser irradiation using 810 nm diode laser on continuous-wave mode for 30 seconds (fluence: 55 J/cm2 , power: 300 mW, spot size: 4.5 mm). In group 5, PACT was performed using topical application of ICG followed by laser irradiation in the same way as the previous group. Bacterial load of oral ulcers was assessed before and after each treatment modality. Besides, rats were sacrificed on the 5th day post ulceration and histological features of healing were evaluated. RESULTS Bacterial load was significantly reduced merely in the PACT-ICG-treated group by one log (P < .0001). Animals in the PACT-ICG-treated group also showed an accelerated healing in comparison with others on the 5th day of an experiment. CONCLUSION Photodynamic antimicrobial chemotherapy using topical application of ICG has a potential to reduce the bacterial load of oral ulcers and accelerate wound repair. Therefore, it can be considered as an alternative to currently available modalities for wound management.

Abstract
Syphilis, a sexually transmitted disease, can be categorized as acquired syphilis and congenital syphilis, manifesting diverse lesions involving multiple sites. Oral manifestations at the primary stage of acquired syphilis are usually characterized by its short period and non-specific varied presentations. And oral ulcers as initial and the only presentation of syphilis oral lesions are infrequent and occur in less than 2% of patients. Because of its transient nature and variable manifestations which could mimic other oral ulcerative lesions, oral syphilis presenting as sole ulceration at early stage can be easily neglected and rather difficult to diagnose. Herein, we report a 35-year-old female patient manifested a sole atypical ulceration on her upper lip for approximately 1 month. We highlighted the importance of early and accurate diagnosis, focused on the characteristics of oral chancre, and gave an insight to the differential diagnoses, which would be enlightening and useful in clinical practice.

Abstract
Introduction: Necrotizing sialometaplasia (NS) is a rare locally destructive inflammatory benign disease that commonly affects the minor salivary glands. It is frequently associated with the glands located in the posterior portion of the hard and soft palates. Low-level laser therapy (LLLT), also called photobiomodulation therapy (PBMT), has been deemed a substantial method for the regenerative wound process. Case Presentation: A 32-year-old male patient was referred with a chief complaint of two asymptomatic crater-like ulcers measuring approximately 1.5 cm wide on the right side of the hard and soft palates, and another measuring 0.3 cm wide on the left side of the hard palate. The lesion had two weeks of evolution followed by a previous infectious "sore throat" event that kept the patient hospitalized for 4 days. A clinical diagnosis of NS was made. LLLT was applied during 2 sessions per week, favoring the total wound healing within 2 weeks. At 3 months of clinical followup, the patient did not present any complication or relapse and was thus released. Conclusion: This is, to our knowledge, the first clinical report of LLLT applied for the management of NS. Large palatal ulcers caused by NS usually have long healing periods. The shortened healing period observed in this case encourages the inclusion of LLLT in any treatment protocol for similar lesions.

Abstract
Nowadays, the heavy burden of oral diseases such as dental caries, periodontitis, endodontic infections, etc., and their consequences on the patients' quality of life indicate a strong need for developing effective therapies. Bacterial infections played an important role in the field of oral diseases, in-depth insight of such oral diseases have given rise to the demand for antibacterial therapeutic strategies. Recently, microporous frameworks have attracted tremendous interest in antibacterial application due to their well-defined porous structures for drug delivery. In addition, intensive efforts have been made to enhance the antibacterial performance of microporous frameworks, such as ion doping, photosensitizer incorporation as building blocks, and surface modifications. This review article aims on the major recent developments of microporous frameworks for antibacterial applications against oral diseases. The first part of this paper puts concentration on the cutting-edge researches on the versatile antibacterial strategies of microporous materials via drug delivery, inherent activity, and structural modification. The second part discusses the antibacterial applications of microporous frameworks against oral diseases. The applications of microporous frameworks not only have promising therapeutic potential to inhibit bacterial plaque-initiated oral infectious diseases, but also have a wide applicability to other biomedical applications.

Abstract
BACKGROUND Diagnosis of oral ulceration is always challenging and has been the source of difficulty because of the remarkable overlap in their clinical presentations. AIM The objective of this review article is to provide updated knowledge and systemic approach regarding oral ulcers diagnosis depending upon clinical picture while excluding the other causative causes. METHODS For this, specialised databases and search engines involving Science Direct, Medline Plus, Scopus, PubMed and authentic textbooks were used to search topics related to the keywords such as oral ulcer, oral infections, vesiculobullous lesion, traumatic ulcer, systematic disease and stomatitis. Associated articles published from 1995 to 2019 in both dental and medical journals including the case reports, case series, original articles and reviews were considered. RESULTS The compilation of the significant data reveals that ulcers can be classified according to (i) duration of onset, (ii) number of ulcers and (iii) etiological factors. Causation of oral ulcers varies from slight trauma to underlying systemic diseases and malignancies. CONCLUSION Oral manifestations must be acknowledged for precise diagnosis and appropriate treatment.

Abstract
Diagnosis of oral ulcerative lesions might be quite challenging. This narrative review article aims to introduce an updated decision tree for diagnosing oral ulcerative lesions on the basis of their diagnostic features. Various general search engines and specialized databases including PubMed, PubMed Central, Medline Plus, EBSCO, Science Direct, Scopus, Embase, and authenticated textbooks were used to find relevant topics by means of MeSH keywords such as “oral ulcer,” “stomatitis,” and “mouth diseases.” Thereafter, English-language articles published since 1983 to 2015 in both medical and dental journals including reviews, meta-analyses, original papers, and case reports were appraised. Upon compilation of the relevant data, oral ulcerative lesions were categorized into three major groups: acute, chronic, and recurrent ulcers and into five subgroups: solitary acute, multiple acute, solitary chronic, multiple chronic, and solitary/multiple recurrent, based on the number and duration of lesions. In total, 29 entities were organized in the form of a decision tree in order to help clinicians establish a logical diagnosis by stepwise progression.

Abstract
The aim of the present study was to evaluate the effects of photobiomodulation (PBM) on cytokine levels and angiogenesis during oral wound healing. Ulcers were made on the dorsum of the tongue in 48 Wistar rats. Irradiation with an indium-gallium-aluminum-phosphide (InGaAlP) laser (660 nm; output power, 40 mW; spot size, 0.04 cm(2)) was performed once a day on two points of the ulcer for 14 days. Two different energy densities were used: 4 J/cm(2) (energy per point 0.16 J, total energy 0.32 J) and 20 J/cm(2) (energy per point 0.8 J, total energy 1.6 J). Tissue levels of interleukin (IL)-1β and tumor necrosis factor (TNF)-α were investigated by enzyme-linked immunosorbent assay (ELISA). Image analysis of CD31-immunostained sections was used to investigate microvessel density (MVD). PBM increased the tissue levels of IL-1β at the early stage of oral wound healing (p < 0.01) and increased the tissue levels of TNF-α during all stages of oral wound healing (p < 0.05). PBM at a dose of 4 J/cm(2) produced more significant results regarding cytokine modulation and was associated with higher MVD at day 5. Collectively, these findings indicate that cytokine modulation and increased angiogenesis are among the basic mechanisms whereby PBM improves oral wound repair.

Abstract
Oral ulcers are a common symptom in clinical practice. Among various causative factors, different types of ulcers in oral cavity exist. Among this, traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) appears to be quite neglected by the clinicians due to the limited knowledge and awareness. On reviewing with a detailed approach to titles and abstracts of articles eliminating duplicates, 40 relevant articles were considered. Randomized studies, review articles, case reports and abstracts were included while conference papers and posters were excluded. Of importance, TUGSE cases been reported only to a minimal extent in the literature. Lack of its awareness tends to lead clinicians to a misconception of cancer. Thus, this particular lesion needs to be differentiated from other malignant lesions to provide a proper mode of treatment. The present article reviews various aspects of the TUGSE with emphasis on the clinical manifestation, pathogenesis, histological, and immunohistochemical study. This study provides the clinician contemporaries, a humble expansion to their knowledge of the disease, based on the searched literature, enabling a more comprehensive management of this rare occurrence.

Oral manifestations of allergic, infectious, and immune-mediated disease. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2014; 2:686-96.

Abstract
Patients often have oral symptoms, and physicians frequently identify lesions during routine oral examination. Being able to associate these concerns and findings with systemic disease is important to providing effective management of these conditions. This review summarizes the etiology, presentation, and treatment of many oral lesions associated with systemic diseases and infections. The primary focus was on lesions associated with allergic, infectious, and immune-mediated disease; however, other common concerns are addressed as well as lesions that may be misinterpreted as disease and how to address unknown lesions.

JOURNAL OF BIOMEDICAL OPTICS 2013; 18:128002. [PMID: 24337496 PMCID: PMC4019369 DOI: 10.1117/1.jbo.18.12.128002] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/28/2013] [Revised: 10/04/2013] [Accepted: 11/05/2013] [Indexed: 06/03/2023]
Abstract
The aim of the present prospective study was to evaluate the impact of laser phototherapy (LPT) on the healing of oral ulcers. Different power densities were used on oral wounds in Wistar rats (n=72) randomly divided into three groups: control (0 J/cm2), 4 J/cm2 laser, and 20 J/cm2 laser. Ulcers (3 mm in diameter) were made on the dorsum of the tongue with a punch. Irradiation with an indium-gallium-aluminum-phosphide laser (660 nm; output power: 40 mW; spot size: 0.04 cm2) was performed once a day in close contact with the ulcer for 14 consecutive days. A statistically significant acceleration in healing time was found with wounds treated with 4 J/cm2 LPT. Moreover, striking differences were found in the ulcer area, healing percentage, degree of reepithelialization, and collagen deposition. The most significant changes occurred after 5 days of irradiation. Based on the conditions employed in the present study, LPT is capable of accelerating the oral mucosa wound-healing process. Moreover, faster and more organized reepithelialization and tissue healing of the oral mucosa were achieved with an energy density of 4 J/cm2 in comparison to 20 J/cm2.

Use of endoscopy with narrow-band imaging system in detecting squamous cell carcinoma in oral chronic non-healing ulcers. Clin Oral Investig 2013; 18:949-59. [PMID: 23835583 DOI: 10.1007/s00784-013-1027-y] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2012] [Accepted: 06/26/2013] [Indexed: 12/26/2022]
Abstract
OBJECTIVES This study seeks to analyze the factors associated with the occurrence of squamous cell carcinoma in oral non-healing ulcers for more than 3 weeks and investigate the role of endoscopy with narrow-band imaging system (NBI) in detecting carcinoma in these lesions. METHODS The demographic and clinicopathological data of patients receiving surgical interventions for chronic oral non-healing ulcers, and the intraepithelial papillary capillary loop patterns shown by NBI were retrospectively reviewed and analyzed. RESULTS A total of 63 patients (41 males and 22 females) with mean age of 57.9 ± 16.7 years were enrolled. In univariate analysis, ulcers with induration, history of oral cancer, and intraepithelial microvasculature of NBI were factors associated with the occurrence of squamous cell carcinoma in oral non-healing ulcers. Multivariate analysis showed that the intraepithelial microvasculature of NBI was the only independent factor predicting the occurrence of carcinoma in oral chronic non-healing ulcers with sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 93.75 %, 91.49 %, 78.95 %, 97.73 %, and 92.06 %, respectively. CONCLUSIONS Morphology of intraepithelial microvasculature of NBI, or twisted, elongated, and destructive pattern of intraepithelial papillary capillary loop, is the only independent factor associated with the occurrence of squamous cell carcinoma in oral chronic non-healing ulcers. Endoscope with NBI is a rapid, safe, and promising tool in detecting squamous cell carcinoma in oral chronic non-healing ulcers.
