RESUMEN

BACKGROUND: After tooth extraction, inevitable resorption of the postextraction socket occurs. Placing an immediate implant does not fully preserve the bone integrity of the socket. Preservation techniques cannot avoid alveolar resorption. In residual atrophies, bone augmentation techniques are necessary for subsequent rehabilitation with implants. The aim of this study was to propose a protocol of immediate loading in short implants as an alternative to bone augmentation techniques, comparing the immediate versus conventional loading, evaluating peri-implant bone loss, the biological and prosthetic complications, the survival of the implant and prosthesis and the patient satisfaction after one year. METHODS: This study consists of a randomized controlled clinical trial. For implant planning, periapical intraoral radiographs and Cone Beam Computed Tomography will be used. All patients will receive Straumann Group® (Basel, Switzerland) titanium-zirconia implants with a 4.1mm or 4.8mm diameter and a 4 mm or 6 mm length. RESULTS: The expected results show similar or even minor bone loss, biological and prosthetic complications, identical or even better survival of the short implants with immediate loading, and greater satisfaction. CONCLUSIONS: Short implants demonstrate similar survival to conventional length implants, with comparable or even minor biological and prosthetic complications and bone loss. Immediate loading gives satisfactory results similar to conventional loading, with similar biological and prosthetic complications, and generally depends on poor hygiene levels. Bone loss is even less, and the satisfaction increases.

RESUMEN

Sleep bruxism is both masticatory muscle activities characterized by repeated or prolonged tooth contact as well as bracing or thrusting of the jaw. This meta-analysis evaluates the differences between sexes and which therapy is most effective in treating bruxism. A literature search was performed on PubMed, Lilacs, Web of Science and Scopus, and articles published from 2000 to 2022 were considered according to the keywords entered. The term "Bruxism" has been combined with "Children" using the boolean connector AND. At the end of the research, 1462 studies were identified from the search conducted on the three engines. Only four were chosen to draw up the present systematic study. The Forrest plot found that photo biomodulation therapy has a higher efficacy (Odds Ratio (OR) 0.10; 95% Confidence Interval (CI) from 0.03 to 0.43), followed by treatment with hydroxyzine (OR 0.19; 95% CI from 0.03 to 1.04). The average between girls and boys with bruxism is 18.5 for boys and 19.5 for girls. This meta-analysis showed that treatment by photobiomodulation has more significant effects on bruxism, followed by treatment with hydroxyisalazine. However, this meta-analysis has limitations due to the diversity of treatment evaluation methods.

RESUMEN

INTRODUCTION: To systematically review existing scientific literature to determine, compare, and evaluate whether concentrated growth factors (CGF) or connective tissue grafts (CTG) is a better treatment alternative for patients with marginal tissue recession (MTR). METHODS: Electronic databases like PubMed, Embase, Scopus, and Google Scholar were screened from the last 20 years reporting treatment of MTR using CGF or CTG and other techniques. Periodontal parameters like probing depth, clinical attachment level, recession depth, recession width, keratinized tissue width, root coverage, increase in gingival thickness and plaque index, and gingival index were compared. Standardized mean difference was used as a summary statistic measure with a random effect model and P value <0.05 as statistically significant. RESULTS: Six studies fulfilled eligibility criteria and were included in qualitative synthesis, of which only 4 studies were suitable for meta-analysis. The pooled estimate through standardized mean difference signifies that CGF was superior to CTG in the reduction of probing depth, gingival index, and plaque index and gain in clinical attachment level while CTG was superior in reducing the recession depth and recession width. Both the procedures had an overall equal effect on keratinized tissue width and root coverage, but these differences were statistically insignificant (P>0.05). Publication bias through the funnel plot showed symmetric distribution without systematic heterogeneity. CONCLUSION: The present study suggests that treatment of MTR with CTG or CGF resulted in clinically favorable outcomes, but no statistically significant differences was observed between these 2 procedures regarding the outcome.

RESUMEN

A 65-year-old Caucasian male was referred to an endodontic specialist practice in a private clinic in December 2019 for the management of an asymptomatic, radiolucent lesion located at the cervical level of the distal root of his right lower first molar, noticed during a routine periapical radiograph. After an accurate evaluation with cone-beam computed tomography (CBCT), the subgingival lesion was diagnosed as a supracrestal external cervical resorption (ECR), with a circumferential spread ⩽90°, confined to dentine without pulp involvement. The lesion was treated with the following sequence: (1) a full flap accessed the ECR, (2) the granulomatous tissue was removed from the root area, (3) the cavity was refreshed and filled with a well-refined and polished resin composite, (4) the flap was sutured at the cemento-enamel junction. A mandibular CBCT scan was performed before treatment, right after treatment, and 3 years postoperatively. Compared to the 3-year posttreatment CBCT scan, the immediate posttreatment one, revealed the absence of bone loss and an unexpected coronal bone remodeling with new bone formation over the treated lesion.

RESUMEN

Dental anxiety, linked to avoiding dental treatment and heightened medical and surgical risks, prompted this systematic review. The objective is to synthesize existing evidence on conscious sedation techniques employed for managing dental anxiety in patients scheduled for third molar extraction surgery, aiming to identify optimal approaches and address knowledge gaps. This systematic review followed the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" checklist and the population, investigation, comparation, outcome framework. The protocol still needs to be registered. A thorough search was conducted, incorporating MEDLINE/PubMed, EMBASE, SCOPUS, clinicaltrials.gov, and the Cochrane Database of Systematic Reviews until February 2024. Only randomized controlled trials were considered, following "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" guidelines. The risk of bias was evaluated following the Cochrane Handbook for Systematic Reviews of Interventions. Eighteen randomized controlled trials involving 2081 patients were included. Certain factors limited the feasibility of a meaningful meta-analysis, leading to a narrative synthesis. Conscious sedation with virtual reality showed an association with improved dental anxiety in 4 studies. One study reported reduced cortisol levels with midazolam compared with a placebo, whereas another noted significant variations in perioperative renin levels with remifentanil versus placebo. This review reveals inconclusive and conflicting findings regarding the role of conscious sedation in managing dental anxiety during third molar extraction surgery. Persistent uncertainties arise due to a need for consistent, standardized outcome measures. Addressing these limitations in study design is crucial for future research.

RESUMEN

BACKGROUND: This study aims to evaluate the differences in terms of Quality of life and the degree of satisfaction with the result obtained between the two groups of patients treated with the orthodontic first approach and surgery first approach, through administered questionnaires inserted in the post-operative phase. METHODS: A total of 40 patients who previously underwent orthognathic surgery were included in this study, 20 treated with the orthodontic first approach and 20 treated with the Surgery First Approach. The impact of orthognathic surgery on patients' quality of life was recorded through the administration of the OHIP-14 test, FACE-Q test scale and FACE-Q test. Comparison between the two groups was done using a nonparametric inferential statistical test, the Mann-Whitney U-test. RESULTS: The results showed no significant differences in terms of quality of life between the two groups. Patients treated with orthodontic first approach presented greater psychological distress and perceived their faces as unattractive. CONCLUSIONS: A worsening of the aesthetics of the face determined by the orthodontic approach before surgery, may not be decisive in the quality of life of patients, which will certainly be better after surgery. SFA and OFA determine in both cases a marked improvement in the patient's quality of life.

RESUMEN

OBJECTIVE: This study aimed to evaluate the effects of sterile saline solution irrigation (lavage) performed after mandibular third molar extraction on postoperative complications, utilizing a split-mouth randomized clinical trial design. METHODS: Seventeen healthy participants requiring bilateral mandibular third molar extraction were enrolled in this single-center study. In each participant, one impacted third molar was designated as the experimental group and subjected to saline lavage at 4 °C. In contrast, the control group was the other impacted third molar, undergoing saline lavage at 25 °C. Various parameters, including postoperative pain, mouth opening, and facial swelling, were assessed using standardized measures and three-dimensional facial scanning at multiple time points. RESULTS: The average age of participants was 26.66 ± 4.1 years, with no postoperative complications observed in either group. The duration of surgery did not significantly differ between groups. Postoperative pain was significantly reduced in the experimental group during the immediate postoperative period compared with the control group, but this difference diminished over time. No significant differences were observed in mouth opening or facial swelling between groups at any time. CONCLUSION: In site 4 °C, sterile saline solution irrigation after mandibular third molar extraction may effectively reduce early postoperative complications, particularly pain, without prolonging surgical duration.

RESUMEN

New surgical techniques using narrow, tilted implants positioned through a magneto-dynamic tool in guided surgery for a Toronto restoration. A 69-year-old woman wanted fixed rehabilitation to replace her removable complete dentures. A cone-beam computed tomography showed significant bone resorption in both the maxillary and mandibular regions. The plan was to load the entire upper arch with six implants immediately, while removable partial dentures were recommended for the lower jaw. The guided surgery project was aligned with the new dentures, and the laboratory created a printed cast with dental implant analogues in planned positions. A metal-reinforced denture was constructed, and surgery was performed to place six narrow implants using the magneto-dynamic instrument. The denture was directly screwed onto multi-unit abutments. Final rehabilitation was completed after 6 months. Narrow implants can be a good option for fixed, full-arch rehabilitations. Further research is needed to confirm these findings on a larger scale.

RESUMEN

Background: Digital technologies enable the accurate replication of occlusion, which is pivotal for stability in maximum intercuspation and dynamic occlusion. CAD softwares generates standardized occlusal morphologies requiring significant adjustments. The consideration of individual mandibular movements during restoration leads to better functional integration. This pilot study evaluates the efficacy of a novel, fully digital protocol for occlusal analysis recording in prosthodontics. Methods: Patients needing single or multiple metal-free restorations were included. Teeth underwent horizontal finish line preparation, while restorations on implants were either directly screwed or used multi-unit abutments. A digital impression (Trios 3 Intraoral Scanner) captured the mouth's elements. Dynamic occlusion was recorded via Patient Specific Motion (PSM). After the placement and functionalization of temporary restorations, subsequent scans included various elements, and CAD software (Dental system) was used for the restoration design. Restorations were milled in monolithic zirconia, pressed from CAD/CAM-milled wax, and sintered. Results: An evaluation of 52 restorations in 37 patients indicated high accuracy in restorations manufactured via the fully digital workflow. Monolithic zirconia was predominantly used. Subtractive (17.3%) and additive (7.7%) occlusal adjustments were mainly chairside. Conclusion: This study underscores the efficacy of meticulous verification measures and a centric contact system in reducing the need for clinical occlusal refinements in prosthetic restorations.

RESUMEN

This experimental anatomic study aimed to investigate the correlations between the mesio-vestibular canal (MB1) and the second mesio-vestibular canal (MB2) of the mesio-vestibular root of the upper sexts using cone-beam computed tomography (CBCT) imaging. A total of 24 extracted maxillary first molars were collected and subjected to CBCT imaging. The presence, location, and morphology of MB1 and MB2 canals were evaluated using axial, coronal, and sagittal CBCT sections. The interrelation between MB1 and MB2 canals was assessed, including their separate canals, merging, and division points. Among the 24 maxillary first molars examined, 86.5% demonstrated the presence of an MB2 canal in addition to MB1. The MB2 and MB1 were confluent in 80% of the cases with a confluent height of 4,16 mm. The mean distance between MB1 and MB2 canals was 1.85 mm. This study provides detailed information on the anatomic correlations between MB1 and MB2 canals of the mesio-vestibular root in the upper sexts using CBCT imaging. The high prevalence of MB2 canals suggests their significance in endodontic procedures and emphasizes the importance of thorough exploration and identification during root canal treatment. The knowledge of the location and morphology of these canals can aid in successful endodontic therapy and enhance treatment outcomes.

RESUMEN

The importance of oral health for overall health makes it critical to establish proper oral hygiene practices in children early on. The traditional approaches to teaching children about dental health may not be successful since they may not be able to keep their interest. Metaverse technology offers a promising alternative, allowing for the design of engaging and immersive worlds that can effectively educate children about oral health. Despite the growing interest in the use of metaverse technology in healthcare, there is a lack of comprehensive reviews on its potential for oral health promotion in children. This review aims to fill this gap by providing an overview of the current state of metaverse-based oral health promotion for children, discussing its benefits and challenges, and highlighting its potential for improving children's oral health. By conducting this review, the authors hope to provide new information on the potential of metaverse-based oral health promotion for children and to contribute to the ongoing discussion on the use of metaverse technology in healthcare. This review may also provide valuable insights for dental organizations and practitioners interested in using metaverse technology to promote oral health and healthy living among children.

RESUMEN

Caries experience of children and complex clinical circumstances are an actual challenge for any healthcare professional. To investigate the early childhood caries (ECC) in autistic and non autistic children (≤4 years of age) evaluating the amount of dental damage and the treatments carried out in both groups. Data regarding the oral health status of 40 patients (≤4 years of age) were assembled. The sample group was constituted of 20 autistic children (12 males with a mean age of 2.5 years and 8 females with a mean age of 3.2 years) whereas 20 patients without the autistic spectrum represented the control group (11 males with a mean age of 3 and 9 females with a mean age of 3.3 years). There were no significant differences between the two groups as regards both the extent of dental damage and the treatments carried out. About the frequency, in the autistic group, the most frequent caries were the white spots and enamel proximal lesions (2.2%), followed by only white spots (1.2%) and brown-black cavities and root stumps (0.6%). In the control group, the brown-black cavities and root stumps represented the most frequent findings (2.2%), followed by white spots and enamel proximal lesions (1.4%) and white spots (0.4%). Regarding the treatments, the most repeated management of dental damage among autistic patients was composite restorations (2.2%) while in nonautistic patients were tooth extractions (2%).

RESUMEN

Nasal septal deviation (NSD) is one of the most common abnormalities impacting the maxillofacial development of children. Herein, we investigated the impact of orthopedic rapid maxillary expansion (RME) on the nasomaxillary complex and NSD in pediatric patients. The study sample consisted of a total of 40 patients divided into two groups. The experimental group included 26 patients (13 females and 13 males) with skeletal maxillary transversal constriction and NSD greater than 1 mm, while the control group comprised 14 patients (6 females and 8 males) with skeletal maxillary transversal constriction but no NSD. All the patients were treated for approximately 15 days with the tooth-tissue born RME device. The activation procedure was to turn the transversal Hyrax screw a quarter turn, twice a day. After that, the device was left in place for a period of five months to facilitate passive retention. Radiographic analysis was performed on posteroanterior (PA) cephalometric radiographs taken at pre-expansion (T1) and post-expansion (T2). The data were evaluated using the Mann-Whitney U and Wilcoxon Sign tests. The experimental group showed a statistically significant decrease (p < 0.05) in the distance from the axis of symmetry to middle of nasal septum (SNM-mid) and to inferior part of the nasal septum (SNI-mid) measurements, indicating a reduction in NSD. Additionally, both experimental and control groups showed a statistically significant increase (p < 0.05) in maxillofacial measurements, including the distance between the nose length (X-SNM and SNM-SNAC), width of the nasal cavity (Pir L-R), basal maxillary width (Mx L-R), vestibular cuspid of upper first molars (CVM + L-R) and lower first molars (CVM-L-R). Based on the study findings, RME was considered effective in achieving craniofacial improvement in pediatric patients with NSD, which positively impacted their healthy growth and development. The improvement in the nasomaxillary complex was similar between genders.

RESUMEN

OBJECTIVES: Sterilization eliminates microbial viability by decreasing the biological load, but likewise have the ability to deteriorate the mechanical properties of an implant material. This study intended to evaluate the effect of repeated moist heat sterilization on implant-abutment interface using two different implant systems. MATERIALS AND METHODS: Forty screw-retained titanium implant-abutment combinations (fixture 3.5 ×10 mm, abutment 2 mm diameter), twenty each from Genesis (Aktiv Implant Systems, United States) and Bredent (SKY, Germany), were divided into four different groups (n = 10) and placed in a computer-aided diagnostic model. The abutments from each group were exposed to first and second autoclave cycle (121°C for 30 minutes), connected back to the fixture and analyzed under scanning electron microscope for marginal gap and surface roughness. RESULTS: Genesis group showed higher marginal gaps on both sides (buccal/mesial [2.8 ± 0.47]; lingual/distal [2.8 ± 0.33]), while Bredent implant-abutment system (IAS) did not show any changes in marginal gaps after autoclaving. Differences within and between the group were found to be statistically significant. Surface roughness for Genesis (243.7 ± 70.30) and Bredent groups (528.9 ± 213.19) was highest at second autoclave, with Bredent implant-abutment showing higher values for surface roughness than Genesis IAS. CONCLUSION: Marginal vertical gap increased with autoclaving for Genesis IAS, while Bredent implant abutments were more stable. Surface roughness increases with autoclaving for both Genesis and Bredent group of IAS.

RESUMEN

BACKGROUND: The treatments with clear aligners (CA) showed an exponential higher percentage in the last years being almost invisible with major patient acceptability and a resulting improvement in quality of life. CA are composed of thermoplastic polyurethane not inert but subjected to changes due to heating and humidity, chewing forces, and prolonged exposure to enzymes in saliva in the oral cavity and external factors. Cigarette smoke (CS) and the aerosol produced by tobacco products with reduced health risks may be considered among the external factors affecting CA. The purpose of this study was the assessment of optical properties (absorbance and transmittance) and roughness of CA after in vitro aging due to exposition to CS and THS2.2, compared to controls. The secondary objective will be the investigation of CS and THS2.2 effects on resin composite inside aligners used for attachments during treatment with CA. METHODS: A total number of 60 CA units will be used and equally divided in three different groups (20 in each): CS group exposed to reference cigarettes smoking, THS2.2 group exposed to aerosol from 20 heat-not-burn sticks, and control group, CG to pure air only. The aligners will present ten introflection for the attachments on the anterior part. In accordance with ISO standard 3402, 3R4F cigarettes and THS2.2 tobacco sticks must undergo conditioning for a minimum of 48 hours and a maximum of 21 days at a temperature of 22±1 °C and a relative humidity of 60±3%. RESULTS: Using spectrophotometry, the optical characteristics (absorbance and transmittance) of each aligner will be evaluated after aging (Jasco UV-vis V630PC, Tokyo, Japan). Each aligner will be cut with a rotating saw from canine to canine prior to the measurements in order to lop off the lingual region and displaying the labial barrier. The absorbance and transmittance measurements will be collected and statistically analyzed with a significance of P<0.05. CONCLUSIONS: Surface roughness of the aligners and attachments inside them will be assessed by 3D scanning microscopy (Infinite Focus G4h). Color of resin composite will be assessed using the (CIE Lab) Commission Internationale de l'Eclairage L*a*b* color space by means of Olympus CrystalEyef dental spectrophotometer. Clinicians should advise patients to refrain from smoking and drinking coffee or tea while wearing aligners for two reasons: first, the color change is unacceptably noticeable when wearing aligners, and second, the material's chemical composition may be slightly altered, which could affect the intended dental movements.

RESUMEN

The present study evaluates the efficacy and clinical outcomes of crestal sinus lift techniques used to elevate the sinus floor simultaneously with bone grafting and implant placement as a possible and reproducible alternative to lateral sinus lift. Patients underwent different crestal sinus elevation techniques. The heterologous biomaterial was used as graft material, and multiple implants were placed simultaneously after sinus augmentation. Radiographic and clinical examinations were performed during follow-up. All procedures were successfully performed without any apparent perforation of the Schneider membrane. The sinus floor was augmented with an average height of 5 mm (range: 2.8-7.4 mm). The implants healed smoothly with healing screws. Peri-implant marginal bone was stable with a mean follow-up of 50 months (range: 33-71 mo). No complications were observed during the follow-up. Based on the limited data collected in this study, the new crestal sinus elevation approach can effectively raise the sinus floor and reduce the incidence of postoperative complications. Other cases with long-term follow-up are needed to confirm and improve this crestal sinus lift technique.

RESUMEN

OBJECTIVES: Orthodontic treatment with clear thermoplastic aligners is in great demand by patients especially for aesthetics. Any alterations in the chemical composition of the thermoplastic material for aligners, subjected to the oral environment and exposure to various commonly used substances, could influence the desired orthodontic movement decreasing the predictability of the treatment. The objective of this study was to determine the chemical-physical characterization by micro-Raman spectroscopy of a thermoplastic material based on polyethylene terephthalate glycol (PET-G) used for the manufacture of Lineo aligners (Micerium Lab, Avegno, Italy) subjected to different staining beverages and cleaning agents. MATERIALS AND METHODS: Twenty-two thermoformed PET-G samples were immersed to various substances of daily use for 10 and 15 days (coffee, tea, Coca-Cola, red wine, colloidal silver disinfectant, nicotine, artificial saliva, cigarette smoke, and different combinations of saliva with some of the previous solutions). Subsequently, the chemical-physical characterization was investigated by micro-Raman spectroscopy. RESULTS: The analysis of the spectra acquired for all the specimens showed no difference in the exposure to the different solvents at 10 and 15 days. Furthermore, having ascertained the heterogeneous surface morphology of the PET-G material due to thermoforming, various deposits were present on all the samples whose consistency and concentration depended on the substance used. CONCLUSION: The spectroscopic investigations have provided a precise and detailed analysis of the qualitative and structural data of the PET-G material under examination. No significant structural modifications of the thermoplastic polymer were found after immersion in different solutions in the exposure times adopted.

RESUMEN

A meta-analysis of scientific literature was conducted to ascertain the superiority between allografts and other regenerative grafts for maxillary sinus floor augmentation (MSFA). Review was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines and registered in PROSPERO-CRD42023392766. Electronic databases like PubMed, Google scholar and Ebsco Host were searched from 2000 to December 2022 for studies reporting MSFA using allografts or other regenerative grafts. Quality assessment of included studies was evaluated using the Cochrane risk of bias (ROB)-2 tool for randomized controlled trials through its domains. Risk of bias summary graph and ROB summary applicability concern were plotted using RevMan software version 5.3. The standardized mean difference was used as a summary statistic measure with random effect model and P value <0.05 as statistically significant. Four studies fulfilled the eligibility criteria and were included in qualitative synthesis, of which all 4 studies were suitable for meta-analysis. Pooled estimate through standardized mean difference signifies that new bone formation was more or less similar for both graft materials, whereas regenerative grafts showed more residual bone grafts (P>0.05). Publication bias through funnel plot showed symmetric distribution with the absence of systematic heterogeneity. Both allografts and other regenerative grafts are equally effective in the MSFA in terms of new bone formation, whereras regenerative grafts showed more residual bone grafts. Furthermore, randomized controlled trials are required to establish evidence in outcomes involving sinus floor augmentation and different graft materials.

RESUMEN

Objective: The present study investigated the clinical potential of managing anxiety during dental procedures to reduce acute attacks in patients with hereditary angioedema (HAE). HAE is a rare disease, little known to physicians and dentists, but with an increased hospitalization rate over the years. HAE is due to a deficiency/dysfunction of the C1 esterase inhibitor, leading to increased vascular permeability. Recommendations for HAE management include long-term and short-term prophylaxis and treatment of acute attacks, but the importance of anxiety control is underestimated. Materials and methods: The authors reviewed the literature to provide the scientific community with an overview of possible protocols for managing anxiety in dental practice and their effectiveness. Management can be used in prosthetics, periodontal and implant surgery, endodontics, and oral surgery. Discussions: Our analysis shows that although there are few articles in the indexed literature, protocols for managing anxiety in HAE patients in dentistry will become increasingly prevalent in the daily clinical practice of dentists due to its benefits. Conclusions: The benefits and better control of intraoperative complications and risks may lead clinicians to use sedation, assessment, or anxiety control techniques in daily clinical practice to reduce such attacks. Clinical relevance: This study suggests that controlling and managing anxiety can help prevent and reduce acute angioedema attacks.

RESUMEN

BACKGROUND: The aim of this study was to investigate oral mucosal changes in patients with confirmed moderate-scale severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. METHODS: We analyzed 85 COVID-19 patients (50 males, 35 females) with an average age of 53.6 years, treated at the prehospital infectious disease center and Aldent University Clinic in Tirana, Albania, from May 2021 to June 2022. RESULTS: Elevated C-reactive protein levels were observed in 82 patients (±44.20), with 20 patients showing significant fibrinogen increase (mean ± 5.85 g/L), and 22 patients having elevated D-Dimer (mean ± 336.6 mg/mL). Despite the absence of anticoagulant history, 13 patients exhibited bleeding. Xerodermia, xerostomia, and angular cheilitis were noted, with 41 patients displaying angular cheilitis. In 82 patients, oral mucosal and tongue examinations revealed color changes from white to bright yellow, with brown edema. Pigmentation in the fixed gingiva of upper and lower front teeth was observed in 35 patients. CONCLUSIONS: Oral mucosal changes during COVID-19 appear more influenced by drug treatment and disease progression than the infection itself, suggesting that secondary factors play a significant role. Despite the oral cavity's potential for viral entry, these changes seem connected to other underlying causes.
