Objectives: Anisakidosis is an emerging, cosmopolitan, and underdiagnosed parasitic disease caused by the accidental ingestion of third-stage anisakid larvae when consuming raw or improperly prepared seafood. Within hours to days of consuming infected raw seafood, patients may develop acute gastrointestinal symptoms including pain, nausea, vomiting, diarrhea and/or constipation, as live anisakid larvae attach to the gastric, or more rarely, the intestinal mucosa. Cases have been reported in which the nematodes succeed at migrating from the stomach upwards to the esophagus and then the oral cavity. Therefore, the purpose of the present literature review is to collect, analyze, summarize and present the relevant epidemiological, clinical, diagnostic, parasitological, therapeutic, and prognostic data concerning anisakidosis localized inside the oral cavity. Methods: An electronic search of the PubMed, Scopus, and Ovid databases was performed with them being accessed for the last time on 29 March 2025. Results: The present literature review identified 13 individual case reports of oral mucosa anisakidosis, which were published in the period 1971–2022. Conclusions: Our review aims to summarize the relevant epidemiological, clinical, diagnostic, parasitological, therapeutic, and prognostic data regarding the oral localization of anisakidosis, a helminthic infection caused by the accidental ingestion of live anisakid larvae and which manifests mainly with gastrointestinal symptoms. Its localization in the oral mucosa appears to be exceptionally rare and, in most cases, occurs with a characteristic clinical picture, defined by the onset of acute mouth or throat pain immediately after the consumption of raw seafood and by the observation of one or more larvae, either lying on or penetrating the oral mucosa. Despite its rarity, dental health professionals and other clinicians should be aware of this disease and the possibility of its intraoral localization, since environmental factors on the one hand, and the adoption of foreign dietary habits on the other, will likely make anisakidosis a much more common disease worldwide in the near future.

Objectives: Burning mouth syndrome (BMS) is a chronic, painful, idiopathic condition of the oral cavity, characterized by the absence of visible pathological changes on the oral mucosa and normal laboratory findings. Recent evidence from the literature supports the classification of BMS as a neuropathic condition. It has been proposed that oxidative stress may contribute to neuropathic pain. N-acetylcysteine (NAC) is an antioxidant that exhibits neuroprotective properties. The aim of the study was to evaluate the efficacy of N-acetyl cysteine in the treatment of burning mouth syndrome (BMS). Methods: Eighty female patients with previously diagnosed BMS were randomly assigned to one out of two groups. One group received N-acetyl cysteine (600 mg/twice a day) and the other received placebo, for an eight-week period. The outcome was measured by the Oral Health Impact Profile-14 (OHIP-14) quality of life questionnaire and Numeric Pain Rating Scale, for burning and discomfort, both before and after completing the therapy. Results: Both groups experienced a significant reduction in burning and discomfort sensations, along with a significant improvement in oral health-related quality of life. However, the difference between the treatment and control group was not statistically significant. Conclusions: NAC does not significantly improve the oral health-related quality of life, burning sensations, and discomfort in BMS subjects compared to placebo. Full article

Objective: Burning mouth syndrome (BMS) is a chronic and often debilitating orofacial pain condition characterized by a burning sensation in the oral mucosa without clear abnormal lesions. While its etiology is considered multifactorial, the underlying pathophysiology remains unclear. This narrative review aims to synthesize existing functional magnetic resonance imaging (fMRI) studies to shed light on the central neural mechanisms contributing to BMS. Methods: A focused electronic search was conducted across the PubMed and J-STAGE databases for relevant articles published in English from January 2000 to May 2025. The review prioritized studies investigating brain structure and function using fMRI in individuals with BMS. Results: Our synthesis of the literature consistently demonstrated that the brains of individuals with BMS exhibit augmented connectivity within the medial pain system and a diminished gray matter volume in the medial prefrontal cortex (mPFC). These findings suggest a crucial role for altered brain circuitry, particularly a reduction in the output of the basal ganglia dopamine system, in the experience of BMS pain. Conclusions: The consistent fMRI findings strongly indicate that BMS involves significant functional and structural brain alterations. The observed changes in the mPFC and its connections to the basal ganglia dopamine system highlight this pathway as a potential target for both pharmacological and non-pharmacological neurological interventions for individuals with BMS.

Objective:Burning mouth syndrome (BMS) is a chronic, intractable orofacial pain condition characterized by a burning sensation in the oral mucosa without discernible lesions. The syndrome predominantly affects menopausal and postmenopausal women and is considered a form of nociplastic pain, where the processing of pain stimuli is altered. Given the significant sex disparity, it is crucial to consider underlying neurobiological differences that may inform treatment. This review explores potential pharmacological targets by examining the pathological mechanisms of BMS. Method of Research: A narrative review approach was utilized to systematically explore and synthesize literature regarding the pathophysiology of BMS and to identify receptors implicated in the enhancement of sensory transmission and the altered processing of pain stimuli. Results: The mechanism of enhanced sensory transmission points to receptors such as TRPV1, P2X3, and CB2 as potential targets. However, considering the nociplastic nature of BMS and its prevalence in women, mechanisms involving altered central pain processing are paramount. Research indicates significant sex differences in glutamate transmission and plasticity within reward-related brain regions. This suggests that the N-methyl-D-aspartate (NMDA) receptor, a cornerstone of glutamate signaling and synaptic plasticity, is a primary therapeutic target. Furthermore, the altered processing of pain and reward, which is a key feature of chronic pain, implicates the brain’s dopaminergic system. A decrease in dopamine D2 receptor function within this system is believed to contribute to the pathology of BMS. Estrogen receptors are also considered relevant due to the menopausal onset. Conclusions: Based on the evidence, the most promising targets for pharmacotherapy in BMS are likely the NMDA receptor and the dopamine D2 receptor. The high prevalence of BMS in women, coupled with known sex differences in the glutamate and dopamine pathways of the reward system, provides a strong rationale for this focus. Effective treatment strategies should therefore aim to modulate these specific systems, directly or indirectly controlling NMDE receptor hyperactivity and addressing the decreased D2 receptor function. Further research into therapies that specifically target this sex-linked neurobiology is essential for developing effective pharmacotherapy for BMS. Full article

Purpose: The objective of this research was to compare the pain-reducing effects of two topical anesthetic agents, 10% atomized lidocaine spray and an EMLA, cream before needle injection applied at different time intervals using parameters of visual analog scale (VAS) score and heart rate (HR). Methods: The randomized split-mouth study included 30 patients (17 boys, 13 girls) aged 8.22 ± 1.8 years. The application of atomized lidocaine spray or cream was randomly used in the maxillary second premolar region. The parameters were measured prior to and following each needle insertion after being applied for 10, 30, 60, and 120 sec. Paired t-test and independent t-test were used for statistic analyses. Results: Compared with the first applications (10 s), atomized lidocaine and EMLA cream applications significantly decreased scores of VAS at the 30 and 120 s applications, respectively. Despite atomized lidocaine showing an early effect compared with EMLA, there were no significant differences in VAS scores between the atomized lidocaine and EMLA cream at the 60 and 120 s measurements. Although HR significantly increased at first anesthetic administration with the atomized lidocaine spray, HR significantly decreased at 30 and 120 s administrations. Conclusions: Atomized 10% lidocaine-based topical anesthetics significantly reduced pain more rapidly and better than EMLA from needle pricks in the buccal mucosa. Therefore, atomized lidocaine topical anesthesia could be used as a substitute for EMLA cream prior to buccal anesthetic administration. On the other hand, further comprehensive studies are required to explore the effects of several doses of atomized lidocaine in various areas of the oral cavity. Full article

Background/Objectives: Diabetic mouth ulcers are a pathological condition of the oral mucosa leading to increases in susceptibility to infection and prolonged wound healing time. Still, there is a lack of natural formulations for treating this condition. Our principal objective was to formulate solid lipid nanoparticles (SLNs) that contained Althaea officinalis (marshmallow) (M.) extract with clove oil (CO.), subsequently integrated into a collagen sponge for enhancing stability, solubility, sustained release, antimicrobial efficacy, and healing power when targeting diabetic oral ulcers. Methods: A factorial design of 34 trials was established to evaluate the influence of lipid concentration (A), SAA concentration (B), lipid type (C), and SAA type (D). The optimized M-CO-SLNs was selected using Design Expert^®, the based Poly dispersibility index (Y2), zeta potential (MV) (Y3), and encapsulation efficiency (%) (Y4). The optimized SLNs were integrated into a collagen sponge matrix and tested for their antibacterial and antifungal efficacy against Pseudomonas aeruginosa, Escherichia coli, and Candida albicans, respectively. Moreover, they were tested for their wound healing power in a diabetic mouth ulcer model. Results: The optimized formula (Run 16: 5% lipid concentration, 4% SAA concentration, capric acid) demonstrated P.S (110 ± 0.76 nm), ZP (−24 ± 0.32 mV), PDI (0.18 ± 0.05), and EE% (90 ± 0.65%.). The optimized M-CO-SLNs formula was incorporated into a cross-linked collagen sponge and showed superior antimicrobial efficacy, an increased swelling ratio, and was effective in an in vivo oral ulcer study, as evidenced by ELISA biomarkers, gene expression analysis, and histological analysis. Conclusions: M-CO-SLNs embedded in collagen sponges is a promising therapeutic formula for clinical application against diabetic mouth ulcers. Full article

Background: This study aimed to investigate the provision of dental care to patients admitted to a public tertiary hospital due to SARS-CoV-2 infection. Methods: A chart review was conducted using medical records of patients admitted with a confirmed diagnosis of SARS-CoV-2 infection at a public tertiary hospital. Patients hospitalized for at least 10 days were included, and data were collected on demographic variables, comorbidities, oral health status, and hospitalization outcomes. Results: A total of 295 patients were included (mean age 60.8 ± 17.4 years). Comorbidities were common, with 29.8% of patients diagnosed with diabetes and 53.3% with hypertension. Only 47.5% of patients received an oral health assessment upon admission, and 58% received oral hygiene care during hospitalization. Oral health evaluations revealed that older adults exhibited significantly higher rates of total edentulism, received more oral hygiene care during hospitalization, and were more likely to undergo oral evaluation at admission. Regarding clinical outcomes, patients with altered mouth opening had significantly lower Glasgow Coma Scale scores (p < 0.001), and those with altered oral mucosa showed reduced oxygen saturation levels (p = 0.006). Conclusions: These study findings highlight the importance of dental care in critically ill COVID-19 patients, particularly in ICU settings. It emphasizes the need for improved dental documentation and integration of dental professionals into hospital-care teams to reduce complications and enhance both oral and systemic health outcomes.

Oral Allergy Syndrome (OAS) is an allergic reaction that occurs upon contact of the mouth and throat with food, leading to symptoms primarily affecting the oral mucosa. In patients with allergic rhinitis, OAS may develop due to cross-reactivity between the pollen allergens responsible for allergic rhinitis, and specific plant-derived foods. This particular type of OAS is known as Pollen Food Allergy Syndrome (PFAS). The difference in prevalence of PFAS across different regions of the world is attributed to various factors, including environmental exposure and dietary habits. Southern Europe’s temperate climate favors the blooming of many allergenic plants, making respiratory allergies and PFAS significant public health concerns. There is a regional variation in pollen in Southern Europe, contributing to differences in the presence of panallergens—such as profilins, pathogenesis-related class 10 (PR-10) proteins and lipid transfer proteins (LTPs)—which mediate PFAS. In order to examine the epidemiology, pathogenesis, and diagnostic approaches of OAS and PFAS, focusing on their prevalence and impact in Southern European adults, a narrative review was performed. Data from Portugal, Spain, France, Italy, Albania, Greece, and Türkiye were retrieved. The main outcome of this review was that the frequency of PFAS varies across studies, not only between countries but also within the same country, due to vegetation variability across regions as well as methodological differences and the year of study. However, despite these differences, PFAS emerges as a common issue in Southern Europe, underscoring the need for effective diagnosis and management. Full article

Background/Objectives: This double-blinded study aimed to evaluate the clinical performance of a giomer restorative material in comparison to a nanotechnology-based restorative system for the restoration of non-carious cervical lesions over a period of 48 months. Methods: A 48-month randomized, controlled, split-mouth trial was conducted with 49 subjects at its baseline, which was reduced to 34 subjects at follow-up, yielding a statistical power of 69.55%. Cervical lesions were restored using either BEAUTIFIL II LS (BL) or 3M/ESPE Filtek Supreme Universal Restorative (FS). Clinical assessments were performed by blinded examiners, excluding the one who placed the restorations. Evaluations were based on the Hickel criteria, covering esthetic, functional, and biological properties, with comparisons made using the Wilcoxon signed-rank test. Results: Hickel scores were analyzed with the Mann–Whitney U test to compare BL and FS groups within subjects. Changes in median Hickel scores, sensitivity, and the gingival index were assessed via Friedman’s test, followed by Wilcoxon signed-rank tests with a Bonferroni correction for post-hoc comparisons. The p-values under 0.05 were considered significant, except with the Bonferroni correction. Statistical analysis showed no significant differences between materials across most Hickel parameters (p > 0.05), though BL exhibited a trend of better surface staining (76.5% excellent with BL vs. 76.5% excellent with FS) and adjacent mucosa, while FS showed slight advantages in surface luster and color match. Conclusions: The clinical evaluation of restorations for non-carious cervical lesions using giomer and nanotechnology-based restorative systems revealed no statistically significant differences according to the Hickel criteria, indicating a similar clinical performance for both restorative materials.

Objectives: Mandibular tori (bilateral, asymptomatic, lingual mandibular protuberances) often remain untreated. When considering surgical resection, understanding the shape, size, and position of the tori at the bone level is crucial. However, collecting accurate information regarding these characteristics is challenging in cases where the oral mucosa is prominent on the floor of the mouth. Methods: We conducted retrospective surveys at Fukuoka Dental College Medical and Dental General Hospital using computed tomographic (CT) image analysis software (Simplant Pro 18.0). The specific aims of this study were to evaluate the appearance rate of mandibular tori by morphological type, size, location, and CT values and their relationship with the remaining teeth in 1176 patients. These patients underwent simple mandibular CT tomography. We used t-tests to analyze the data. Results: Approximately 10% of the identified tori were pedunculated and difficult to diagnose through visual inspection alone. In all the age groups > 30 years, patients with mandibular tori had a lower rate of tooth loss and a higher rate of remaining occlusal support than healthy subjects. The mean CT value of the mandibular tori was >1350 Hounsfield units (HU). Conclusions: These findings provide insights into future classification and treatment planning for mandibular tori, including that in regard to mandibular ridge resection and factors that may contribute to mandibular torus development or progression, and validate the use of excised bone tissue as a bone graft material.

Background: The study aimed to compare the effectiveness of photodynamic therapy (PDT) and topical clobetasol therapy in treating oral lichen planus (OLP). To address the absence of commercially available drug carriers, innovative proprietary solutions were developed. These carriers were designed to enhance the therapies: one for the photosensitizer to reduce its contact time with the mucosa, and another for the steroid to prolong its contact duration. Methods: A randomized, single-blind clinical trial lasting three months was conducted on 29 patients with bilateral oral lichen planus using a full contralateral split-mouth design. The authors utilized proprietary carriers containing 5% methylene blue and 0.025%. Lesion size, as well as scores on the Thongprasom, Abisis, and VASs, were assessed during the study. Results: Relatively low rates of complete remission of lichen were demonstrated immediately after treatment, 10.3% after PDT and 3.4% after clobetasol, but after 3 months, 79% after PDT, and 62% after CLO. After 3 months of treatment, a reduction of 79.88% for PDT and 56.3% for CLO in the area of the evaluated lesions was achieved. Conclusions: PDT emerges as an equally effective method for treating OLP in terms of clinical outcomes, with the added advantage of avoiding many complications associated with conventional therapy.

Background: This investigation focused on the influence of collagen on the integrity of the Schneiderian membrane during maxillary sinus augmentation in a rabbit model. The aim of this study was to elucidate the relationship between membrane integrity and bone regeneration in augmented maxillary sinuses using collagenated and non-collagenated grafts, through detailed histological and histomorphometric analyses. Methods: In this forward-looking, randomized, split-mouth design, bilateral maxillary sinus augmentation was conducted on 12 rabbits. One sinus was filled with deproteinized bovine bone material (DBBM) as the grafting material (non-collagenated; control), while a combination of DBBM particles integrated with 10% porcine-derived type I collagen was used in the contralateral sinus (collagenated; test). Histological analyses were carried out following healing periods of 2 and 12 weeks. Results: At the 2-week time point, six sites of thinned mucosa (<40 µm) and no perforations were observed in the collagenated group, while twenty-one thinned mucosa sites (p = 0.027 between test and control) and two perforations (p = 0.175 between test and control) were found in the non-collagenated group. After 12 weeks of healing, the number of sites with thinned mucosa was 20 in the collagenated group and 19 in the non-collagenated group, with four perforations observed in each group. These perforations were distributed across three sinuses in the collagenated group and two sinuses in the non-collagenated group. No statistically significant differences were found between the groups. Conclusions: The addition of 10% collagen to deproteinized bovine bone mineral initially provided protection against mucosal thinning and perforation after 2 weeks of healing. However, by week 12, this protective effect diminished, resulting in similar rates of mucosal thinning and perforations in both groups. Full article

Background/Objectives: Films in the mouth offer a promising alternative drug delivery system for oral administration, with several advantages over traditional oral formulations. Furthermore, their non-invasive nature and easy administration make them conducive to increasing patient compliance. The use of active agents in these films can further improve their drug delivery properties, making them an even more useful drug delivery system. Methods: In this research, carrageenan was used as a polymer, while glycerine was added as a plasticizer, furthermore, lidocaine hydrochloride and diclofenac sodium were used as the active agents. The prepared films were characterized by analytical techniques. Results: The results showed that glycerine reduced the mucoadhesivity and breaking hardness of the films and increasing the temperature made the films brittle. These results are also confirmed by the statistical analysis. Based on the FTIR results, glycerine can be used in films without structural changes. Conclusions: Based on the findings, films prepared from a solution with a concentration of 1.5% carrageenan and 1.5% glycerine at 70 °C are suitable as a drug delivery system for use on the buccal mucosa when combined with active agents. Carrageenan was successfully used as a carrier for two different types of active agents. Full article

Background: Inflammatory bowel disease (IBD), encompassing ulcerative colitis and Crohn’s disease, is a heterogeneous chronic condition characterized by periods of relapse and remission. Ulcerative colitis involves inflammation of the colon and rectum mucosa, while Crohn’s disease causes deeper, transmural inflammation affecting all four gut layers from the mouth to the anus and can lead to complications such as fistulation. IBD significantly impacts patients’ physical and psychological well-being, thus reducing their quality of life (QoL). We aimed to evaluate the effectiveness of nursing intervention facilitated through telephone and email support in improving the quality of life (QoL) of Inflammatory Bowel Disease (IBD) patients. Methods: A pilot comparative observational design with pre-test and post-test assessments was employed, involving 50 participants assigned to either an intervention group (Group A, n = 26) or a control group (Group B, n = 24). Group A received regular telephone consultations and prompt email responses from trained nurses; Group B received standard care. Data were collected at baseline and six months post-intervention (T1) using the Patient-Reported Outcomes Measurement Information System (PROMIS^®) and Pittsburgh Sleep Quality Index. Results: Group A showed significant improvements in anxiety, depression, fatigue, and sleep quality, with p-values indicating the significance of these findings. Conclusions: Tailored nursing support via remote communication significantly benefits IBD patients by alleviating psychological distress and enhancing their overall well-being, underscoring the importance of integrating such interventions into standard IBD care practices.

It is challenging to deliver therapeutics in the oral environment due to the wet surfaces, the nature of the mucosa and the potential for saliva washout. In this study, the development of a mucoadhesive dimethicone-based oral carrier system for adhesion to the hard tissue and mucosa in the mouth was examined. This study reports the viscosity and mucoadhesion of dimethicone based polymer blends. The viscosity of the materials was measured using a rheometer. The mucoadhesion of these materials was determined as the work of adhesion and peak tack force using the tensile test method with a texture analyzer. Materials were prepared with either calcium and phosphate salts or sodium fluoride as potential therapeutics for promoting remineralization and treating dentin hypersensitivity by mechanical occlusion. Scanning electron microscopy was used to look at mineral deposition on the surface of dental hard tissue after the application of the dimethicone-based formulations. The results of this study confirm the potential for using these dimethicone-based materials as mucoadhesive therapeutic delivery systems in the oral environment. Full article
