RESUMEN
The oral cavity is a highly regenerative epithelial tissue that results in minimal scarring after injury. This protocol describes the preparation of a mouse palate wound model. The protocol includes steps to place an excisional wound on the mouse palate, followed by harvesting of wound tissue and bone decalcification. We detail how to overcome the technical challenge of limited anatomical space, avoid damaging the nasal cavity, manage bleeding, and collect tissue for downstream genomic or immunohistochemical analysis.

Pediatric cervical spine, blunt cerebrovascular, and penetrating palate injuries are rare but potentially life-threatening injuries that demand immediate stabilization and treatment. Balancing the risk of a missed injury with radiation exposure and the need for sedation is critical in evaluating children for these injuries. Unfortunately, effective clinical decision tools used in adult trauma cannot be uniformly applied to children. Careful risk stratification based on history, mechanism and examination is imperative to evaluate these injuries judiciously in the pediatric population. This article presents a review of the most up-to-date literature on pediatric neck trauma.

BACKGROUND/OBJECTIVE: Electrical stimulation (ES) has been used to treat chronic wound and other clinical applications, showing favorable results in wound closure. It was hypothesized that ES can present a positive effect on oral mucosa healing. The aim of this study was to investigate the effects of ES during the palatal mucosa early healing process in Swiss mice. METHODS: Ninety animals were divided into two groups: Control (C; nâ¯=â¯45), which received Sham ES applications, and Test (ES; nâ¯=â¯45), which received ES (100⯵A; 9â¯kHz; 660 mVpp) once a day for 3 days. A full thickness wound was performed with a 1.5â¯mm diameter biopsy punch in the hard palate. Histologically, the following parameters were evaluated: palatal wound closure and epithelial and connective wound edge distance (EED and CED). Furthermore, IL-1ß, IL-6, IL-10 TNF-α, and VEGF cytokine levels were evaluated by multiplex assay. The percentage of collagen fibers was assessed using the polarization method and the Smad proteins using the immunofluorescence method. RESULTS: Palatal wound closure presented a significant reduction on day 5 in the ES group (pâ¯=â¯0.01). Additionally, both EED and CED were shorter for all time points in the ES group (pâ¯<â¯0.05), and the inflammatory markers IL-6, IL-10, TNF-α, and VEGF were reduced (pâ¯<â¯0.05). There were no differences in collagen fibers and phospho-Smad2 between the groups. CONCLUSION: ES had a positive effect on early palatal wound closure outcomes, as well as on inflammatory markers.

Surgeons are always in a dilemma for the management of paediatric facial fractures due to distinctive nature of growing facial skeleton. The ultimate treatment goal for paediatric fractures should be as conservative as possible with least invasive surgical approach that will access the fracture and least invasive surgical fixation that will allow stable reduction and will prevent any growth disturbances. We are presenting a case of 4- year old with panfacial fracture managed according to this principle using transmucosal titanium plates with acylic splint for sagittal split of palate.

BACKGROUND AND OBJECTIVES: Subepithelial connective tissue graft (SCTG) from the palate has been considered as the "gold standard" for the treatment of deep gingival recessions. A single-incision technique was reported to allow primary wound healing. A palatal single incision was performed in a rat model. The present study assessed the histology and histomorphometry of palatal wound healing following surgical closure with primary intention. MATERIALS AND METHODS: Twenty-six 6-month-old male Wistar rats weighing 427-650 g. An incision was made on the maxillary palate. A full thickness flap was raised palatally, and then repositioned and sutured. Two experimental groups: S-Study group, I-Intact control group. Half of the animals were sacrificed 7 days and the remaining 14 days postoperatively. Outcome parameters included-epithelial gap; inflammatory infiltration; vascular fraction, expression of myofibroblasts and stem cell markers within the oral epithelium and stromal cells and physical properties of stromal collagen fibers. Investigations were performed at two time-points (7 and 14 days) during the wound healing process. RESULTS: The epithelial gap closed completely after 14 days. The inflammatory reaction and vascular fraction were relatively low. Surgical trauma downregulated the expression of cytokeratin (CK) 14 and CK 15, which returned to normal after 14 days. Epithelial differentiation was mediated through upregulation of connective tissue sex- determining-region-Y-box2 (SOX2). Epithelial SOX2, CD34, alpha smooth muscle actin (αSMA) and physical properties of stromal collagen fibers were not influenced by the surgical trauma. CONCLUSIONS: Surgical trauma followed by palatal wound healing with primary intention in a rat model heals within 14 days. It induces minimal inflammatory infiltration and vascular proliferation. Epithelization is exerted through promotion of epithelial differentiation from stem cells by connective tissue SOX2.

Fibroblast injury and autophagy dysfunction have been shown to contribute to the persistence of oral wounds. Recently, microRNAs have emerged as vital regulators and fine tuners of various pathophysiological cellular processes that influence the wound healing process. This study explored the biological function and regulatory mechanism of miRNA-21 (miR-21) in the healing of oral wounds by interfering with autophagy. Healthy gingival cells derived from wild-type (WT) and from miR-21KO mice were characterized by immunocytofluorescence, and changes in wound healing were subsequently assessed using an in vitro scratch wound healing assay. The roles of critical proteins required for autophagy, autophagy related 5 (ATG5) and Bcl-2 interacting coiled-coil protein 1 (Beclin1) were evaluated by immunohistochemistry. Human gingival fibroblasts (HGFs) were transfected with a miR-21 mimic and a miR-negative control, and the relative expression of miR-21, ATG5, Beclin1 and LC3-I/II was characterized by qRT-PCR and Western blot. Pathological changes were observed in a palatal wound healing model using WT and miR-21KO mice. Immunohistochemistry was used to examine extracellular matrix (ECM) proteins and autophagy markers. Cell migration was delayed in gingiva-derived mesenchymal stem cells (GMSCs) from miR-21KO mice compared with WT mice. The expression of ATG5 and Beclin1 was significantly up-regulated in miR-21KO gingiva. Transfection of a miR-21 mimic into HGFs inhibited autophagy and up-regulated miR-21 expression. Knockdown of miR-21 suppressed the expression of fibronectin and CTGF, enhanced the autophagy effect of fibroblasts, suggesting that autophagy is involved in miR-21 regulated palatal wound healing. Taken together, these results suggest that miR-21 promotes oral wound healing by increasing ECM production through the inhibition of autophagy and facilitates clinical management of wound healing.

The aim of the study was to study the effect of the gel on the basis of recombinant human angiogenin on the rate of regeneration of donor palatal wounds. The study involved 20 patients (8 men and 12 women) aged 32 to 55 years. Patients were divided into two groups: the 1st group is a study group (n=10), whose patients in the postoperative period used a gel based on recombinant human angiogenin, the 2nd group is a control group (n=10) in which a gel based on recombinant human angiogenin was not used. Patients in both study groups underwent vestibuloplasty with simultaneous plasty of the attached keratinized gingiva with a free gingival graft from the area of the hard palate. The operations were carried out at the stage of disclosing dental implants, simultaneously with the installation of healing abatements or 4 weeks before dental implantation. For histological examination, tissue samples were obtained from the region of the edge of the donor's wounds of the palate at the 7th and 14th days after surgery. As a result of the study, significant differences were found in the comparison groups when assessing the processes of inflammation, angiogenesis and epithelization. The local application of the gel containing recombinant human angiogenin resulted in a rapid decrease in the intensity of inflammation in lamina propria mucosae and a significant decrease in the bulk density of cell infiltrates, accelerating regeneration. This is primarily due to the stimulation of the development of epidermal growth factor (EGF), vascular endothelial growth factor (VEGF) and increased blood supply to the affected area, as well as an increase in the proportion of fibroblasts. The most important observation was the increase in the rate of epithelialization of donor wounds of the hard palate.

Background: Postoperative complications occur after periodontal plastic surgeries, but an ideal treatment to overcome them has not been found yet. Aims: To evaluate the effects of topically applied Oral-norm gel on the healing of excisional wounds. Study Design: Animal experiment. Methods: Excisional wounds with a diameter of 3 mm were made in the center of the palatal mucosa of 63 Sprague Dawley rats. Seven animals were sacrificed at time 0. The remaining rats were divided into two groups: a test group in which the topical Oral-norm gel was applied three times a day and a control group in which nothing was applied. Seven animals in each group were sacrificed at 3, 7, 14, and 21 days. Mean wound surface area was measured photographically, while wound healing and width were evaluated microscopically. Results: The mean wound surface area decreased significantly after 3 days in both groups (p<0.001). Between days 3 and 7, the mean wound surface area decreased from 6.62 (2.85) to 0.83 (1.62) mm2 in the control group and 5.07 (0.88) to 1.42 (1.67) mm2 in the test group. The wound width decreased significantly on day 7 in both groups (p<0.001), with no further changes by day 14. Both groups had a significant increase in inflammation and vascularization on day 3 (p<0.001), with a reduction thereafter. No significant differences in macroscopic and microscopic measurements were observed between the groups at any time point (p>0.05). Conclusion: The Oral-norm gel has no positive healing effects in the palatal mucosa of rats.

From time to time, severe or fatal injuries caused by small caliber air rifle projectiles are seen. In forensic sciences, the theoretical wounding potential of these weapons and projectiles is widely known. Usually, shots against the skull were reported and, in these cases, penetrating the eyes or thin bone layers of the temporal region. Amongst a huge number of different projectiles available for air guns, sub-caliber 4.4-mm (.173) caliber steel ball projectiles were used in an unusual suicide case. This case led to fundamental questions concerning wound ballistics. An 82-year-old man shot once against his right temporal region and twice into his mouth with a 4.5-mm (.177) caliber air rifle. Because of the exceptionally deep penetration of the base of the skull and the use of spherical-shaped sub-caliber air rifle projectiles, terminal ballistic features were analyzed and compared to results published in forensic literature. Test shots using the same weapon and similar projectiles were fired into ballistic gelatin to measure and calculate basic wound ballistic variables of cal. 4.4-mm (.173) steel balls. In comparison, further test shots with cal. 4.5-mm (.177) steel balls BB (ball bearing), flat-headed and pointed air rifle pellets ("diabolos") were carried out. The theoretical penetration depth in solid bone was calculated with 36.4 mm, and test shots in gelatin from hard contact produced an on-average wound track of 120 mm underlining the potential wounding effect. Furthermore, spherical projectiles could roll back and forth within the barrel, and an air cushion between projectile and breechblock can reduce muzzle velocity by more than half, explaining the retained missile in the temporal region.

Purpose: Assess how pediatric dentists (PD) and general practitioners (GP) manage after-hours pediatric dental emergencies according to perceived urgency. Methods: A survey was e-mailed to PD and GP in North Carolina. Participants responded to management of 18 cases (primary and permanent dentition) according to perceived urgency. Repeated-measures logistic regression was used to analyze factors influencing perception of clinical scenarios. Results: Response rates for PD and GP were 45.5% and 36.3%, respectively. Perceived urgency varied by clinical scenarios, dentition (primary vs. permanent), and practitioner (PD vs. GP) (P<.001). Practitioners with fewer years in practice or seeing fewer pediatric patients managed more cases as urgent. Traumatic injuries in primary dentition (intrusion, pulp exposure, palatal displacement, avulsion) were managed as more urgent by GP than PD (P<.001). Emergencies related to infection and permanent dentition were perceived similarly by PD and GP. Conclusions: Clinical scenarios highlighted disagreement in the management of after-hours pediatric dental emergencies between GP and PD, especially trauma in primary dentition. General practitioners tended to refer to an ED or see urgently, and PD tended to defer care. By identifying needs for improved education in dental trauma management, we can increase utilization of the dental home, avoiding use of overburdened EDs.

BACKGROUND AND OBJECTIVE: To the best of our knowledge, the healing time for toothbrush-induced gingival abrasions in humans has not yet been explored. The aim of this study was to evaluate the time needed to heal for toothbrush-induced abrasions of the keratinized mucosa of the palate. MATERIAL AND METHODS: In patients without, with mild periodontitis or with periodontitis, gingival abrasion lesions were induced at the keratinized mucosa of the palate by brushing up to 2 minutes. Healing as observed clinically was followed via calibrated digital photographs of the lesion after staining, every 24 hours until the lesion had resolved. In patients without or with only mild periodontitis, the healing time of lesions caused by 30 seconds and 1 minute of brushing was also recorded. RESULTS: Thirty-one participants (11 without or with mild periodontitis, 20 with periodontitis) met the inclusion criteria. In patients without or with mild periodontitis, the lesions induced by brushing for 2 minutes diminished by 48.7% of their original surface area within 24 hours. In patients with periodontitis the respective outcome was 45.4% (P = .87). Abrasions caused by 2 minutes of brushing needed more than 24 hours to heal completely. When decreasing the time exposed to trauma, fewer lesions were visible at baseline and the time needed to heal decreased. The subgroup of smokers was too small to evaluate any effect. CONCLUSION: The longer the exposure time of the keratinized mucosa of the palate to trauma, the more lesions were visible, the larger the abrasions were and the more time they needed to heal completely. More studies are needed to investigate the role of smoking, gingival biotype and to link these findings with gingival recessions.

IMPORTANCE: The sequelae of palate trauma vary from minimal discomfort to major neurovascular injury. Infrequency of palate trauma and clinician unfamiliarity with the disease process may lead to variation in evaluation, treatment, and disposition in the emergency department (ED). OBJECTIVES: To measure the incidence of primary palate trauma visits to US emergency departments with analysis of demographics, disposition, and repair and to determine frequency and factors associated with head and neck imaging. DESIGN, SETTING, AND PARTICIPANTS: A retrospective analysis using the Healthcare Cost and Utilization Project Nationwide Emergency Department Sample was performed of 22â¯094 patients presenting to US emergency departments from 2006 to 2010 with a primary diagnosis of palate trauma. Data analysis was conducted from March 29, 2016, to November 18, 2017. MAIN OUTCOMES AND MEASURES: National estimates of palate trauma were calculated from weights available within the database. Palate repair was identified by International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes. Imaging was calculated from reliable Current Procedural Terminology coding facilities identified using a previously published method. Logistic models were calculated to identify clinical associations for admission, imaging, and palate repair. RESULTS: A total of 22â¯094 patients (13â¯967 male and 8121 female patients, 6 missing data on sex; median age, 2.8 years [interquartile range, 1.1-6.1 years]) with primary palate trauma presented to US emergency departments during the study period. Total hospital visits decreased from 4715 (1.58 per 100â¯000 people) to 3915 (1.26 per 100â¯000 people) during the 5-year study period. A total of 19â¯819 patients (89.7%) had routine discharge from the hospital, while palate repair (965 [4.4%]) and mortality (34 [0.2%]) were rare. Complicated palate trauma (odds ratio [OR], 5.32; 95% CI, 3.10-9.15), male sex (OR, 1.57; 95% CI, 1.11-2.21), codiagnosis status (OR, 2.75; 95% CI, 1.84-4.12), and residence in the Northeast vs South (OR, 2.73; 95% CI, 1.11-6.71) increased the likelihood of admission, which was infrequent (1027 patients [4.6%]). After restriction to reliable Current Procedural Terminology coding facilities, head and neck imaging occurred in 823 of 6897 patients (11.9%). Factors associated with head and neck imaging included living in a medium vs large metropolitan area (OR 1.62; 95% CI, 1.04-2.55), while living in the Midwest vs South region (OR, 0.43; 95% CI, 0.25-0.74) had a negative association with imaging. CONCLUSIONS AND RELEVANCE: Although it is often suggested in the otolaryngology literature to perform imaging, primary palate trauma usually results in a routine discharge home without imaging or repair. Imaging frequency should be noted since palate trauma could have life-threatening neurovascular sequelae, which presents an opportunity to define and promote optimal management for potential neurologic sequelae in the patients who were not imaged.

Self-inflicted injury to oral mucosa is a rare entity. These injuries can be premeditated, accidental, or can result from an abnormal habit. These uncommon gingival injuries can sometimes test the clinician's diagnostic abilities as well as treatment planning skills. In conventional treatment, removal of etiology and application of topical drugs is usually sufficient for healing. However, some cases require alternative or adjunctive wound healing methods. Low-level laser therapy (LLLT) has been reported to be effective in pain management and improvement in wound healing through promotion, fortification, and commissioning of cellular cycle to generate productive and substitute cells. This report presents a case of 25-year-old female with complaints of a painful, nonhealing wound on the palate for last 6 months. She had an unusual habit of keeping burning matchsticks in her mouth. Although she had quit the habit 2 months ago after psychiatric counseling, the wound on her palate did not show any improvement in symptoms. Based on the history and clinical findings, diagnosis of chronic wound by self-inflicted thermal injury was made. LLLT was administered on the wound every 48 hours for next 10 days. The burn wound healed completely after five applications of LLLT.

Graphite tattoo, a rare finding in children, is characterized by a localized blue-grey macule of variable sizes and shapes. Intraoral graphite implantation may cause this pigmentation through accidental injury with a graphite pencil. The purpose of this paper is to report an unusual case of graphite tattoo involving the anterior palate region in a seven-year-old girl. A diagnosis was made based on clinical and radiographic examinations and histopathology features. This report also highlights the importance of differential diagnosis and management of oral benign and malignant pigmented lesions in children.

We carried out an in vivo study to evaluate the potential usefulness of a novel bioengineered bone substitute for the repair of palate defects in laboratory rabbits, using tissue-engineering methods. Our results showed that the use of a bioengineered bone substitute was associated with more symmetrical palate growth as compared to the controls, and the length and height of the palate were very similar on both sides of the palate, with differences from negative controls 4 months after artificial bone grafting for bone length. The histological analysis revealed that the regenerated bone was well organized and expressed osteocalcin. In contrast, bone corresponding to control animals without tissue grafting was immature, with areas of osteoid tissue and remodelling, as determined by MMP-14 expression. These results suggest that bone substitutes may be a useful strategy to induce the formation of a well-structured palate bone, which could prevent the growth alterations found in cleft palate patients. This opens a door to a future clinical application of these bone substitutes. Copyright © 2015 John Wiley & Sons, Ltd.

INTRODUCTION: Over the last few years, oral and pharyngeal signs and symptoms due to oral sex have increased significantly. However, no review articles related to this subject have been found in the medical literature. The objective of our study was to identify otorhinolaryngological manifestations associated with orogenital/oroanal contact, both in adults and children, in the context of consensual sex or sexual abuse. METHODS: We performed a review of the medical literature on otorhinolaryngological pathology associated with oral sex published in the last 20 years in the PubMed database. RESULTS: Otorhinolaryngological manifestations secondary to oral sex practice in adults can be infectious, tumoral or secondary to trauma. The more common signs and symptoms found in the literature were human papillomavirus infection (above all, condyloma acuminata and papilloma/condyloma), oral or pharyngeal syphilis, gonococcal pharyngitis, herpes simplex virus infection and pharyngitis from Chlamydia trachomatis. The incidence of human papillomavirus -induced oropharyngeal carcinoma has dramatically increased. In children past the neonatal period, the presence of condyloma acuminatus, syphilis, gonorrhoea or palatal ecchymosis (the last one, unless justified by other causes) should make us suspect sexual abuse. CONCLUSIONS: Sexual habits have changed in the last decades, resulting in the appearance of otorhinolaryngological pathology that was rarely seen previously. For this reason, it is important for primary care physicians to have knowledge about the subject to perform correct diagnosis and posterior treatment. Some sexual abuse cases in children may also be suspected based on the knowledge of the characteristic oropharyngeal manifestations secondary to them.
