The number of patients undergoing a surgical resection of the maxilla for oncological reasons is constantly increasing, the most common complication of which remains the communication between oral and nasal cavities. On the basis of data arising from the literature regarding the treatment options of maxillary oncological post-surgical defects, obturator prosthesis remains the most used worldwide. We studied 25 patients (with at least 1-year follow up) rehabilitated by obturator prosthesis after maxillary resection leading to oro-nasal communication, providing data on the objective/subjective evaluation of such rehabilitation and mastication performance measured by a two-color chewing gum test. The type of defect was classified according to the classification system proposed by Aramany. Among the patients in our study, 72% rated a higher score for either stability and retention than for aesthetic appearance, as confirmed by the Kapur score rated by clinicians. The two-color chewing gum test shows similar results as only one patient had insufficient chewing function. Interestingly, we found no correlation between the masticatory function and residual denture, confirming that the maxillary obturator remains a predictable solution in such patients regardless of the anatomical alterations following surgery.
ObjectivesGrowing evidence exists about post‐COVID condition/syndrome as sequelae of Sars‐CoV‐2 infection in healed patients, possibly involving the lungs, brain, kidney, cardiovascular and neuromuscular system, as well the persistency of taste dysfunction. Such symptoms develop during or after infection and continue for more than 12 weeks with pathogenesis related to virus persistency but variable by organs or systems.Materials and MethodsWe recently observed six patients recovered from COVID‐19 and with negative RT‐PCR testing, showing oral mucosa lesions (mainly ulcers) overlapping those occurring in the acute phase, persisting up to 20 days and thus needing a biopsy with histological investigation and spike protein evaluation by immunohistochemistry.ResultsWe found epithelial ulceration, inflammatory infiltrate, vessels with increased diameter and flattened endothelium but no thrombi formation; also, we found a weak epithelial SARS‐CoV‐2 positivity limited to the basal/spinosum layers, progressively decreasing toward the periphery, and the intraepithelial lymphomonocytes, endothelium, and perivascular pericytes too.ConclusionsOur findings provide evidence that SARS‐CoV‐2 can persist, as for other organs/systems, also in the oral epithelium/mucosa after the acute phase and can be responsible for lesions, although by a pathogenetic mechanism that should be better defined but certainly referable as the oral mucosa counterpart of post‐COVID syndrome.
Background The study aims to describe the lingual laser frenotomy perioperative protocol for newborns with ankyloglossia with or without breastfeeding difficulties developed by Odontostomatology and Neonatology and Neonatal Intensive Care Units of the Aldo Moro University of Bari. Methods Authors carried out a prospective observational cohort study. Newborns with ankyloglossia (classified by using both Coryllos’ and Hazelbaker’s criteria) with or without difficult breastfeeding (according to Infant Breastfeeding Assessment Tool) underwent diode laser frenotomy (800 ± 10 nm; 5 W; continuous wave mode; contact technique; under topical anesthesia) and follow-up visits after seven and thirty days postoperatively. The authors analyzed as main outcomes the perioperative pain intensity measured by the C.R.I.E.S. scale, the occurrence of complications and quality of healing, the quality of breastfeeding, newborn’s postoperative weight gain, maternal nipple pain, and the presence of lesions as secondary outcomes. Results Fifty-six newborns were included in the current study. Intraoperative mean pain intensity was 5.7 ± 0.5 points, resolved within thirty postoperative minutes. Observed complications were mild punctuating bleeding, carbonization of the irradiated site, and transitory restlessness. All wounds were completely healed within the thirtieth postoperative day. During follow-up, a significant breastfeeding improvement was evident with satisfactory newborns’ weight gain and a significant reduction of nipple pain and lesions (p < .05). Conclusion Our lingual laser frenotomy protocol provided significant breastfeeding improvement in the mother-newborn dyads with low intraoperative pain and no significant complications.
Background: This study describes the management protocol for capillary-venous malformations in pediatric patients and reports the epidemiology of diagnosed and treated cases at the Unit of Odontostomatology of the Aldo Moro University of Bari from 2014 to 2022. Methods: The authors classified the intraoral and perioral capillary-venous malformations by superficial diameter (<1 cm, 1–3 cm, >3 cm) and ultrasonographical depth extension (≤5 mm, >5 mm). All patients underwent pulsed-mode diode laser transmucosal photocoagulation (8–12 W/cm2); those with malformations that were wide (>3 cm) and deep (>5 mm) received intralesional photocoagulation, too (13 W/cm2). The children received general anesthesia based on their compliance and lesions’ extension. The follow-up lasted six months. Results: A total of 22 females and 14 males (age range 4–18 years) presented 63 capillary-venous malformations. Five patients with Sturge–Weber syndrome, seven with hereditary hemorrhagic telangiectasia, and five with angiomatosis showed multiple malformations. The authors found no intraoperative or postoperative complications. Seventeen patients with lesions >1 cm and >5 mm deep required multiple laser sessions to heal. Conclusion: The results of the current study support diode laser photocoagulation as the gold standard for the treatment of intraoral and perioral capillary-venous malformations in pediatric patients.
Background: Zinc L-carnosine promotes the transition from the inflammatory to the proliferative phase of wound healing by reducing the expression of pro-inflammatory signals and enhancing the expression of anti-inflammatory signals. This prospective cohort study aims to test the effect of a zinc–L-carnosine mouthwash in promoting oral surgical wound healing. Methods: From October 2022 to February 2023, the authors enrolled healthy adult volunteers who needed the extraction of bilateral molars at the Unit of Dentistry of the University of Bari. The authors studied the baseline wound healing of each patient after the first extraction. Three months later, the patients underwent the second extraction and rinsed their mouths with zinc–L-carnosine mouthwash twice per day for the following 28 postoperative days. For a month after each extraction, the patients received weekly follow-up visits by an oral surgeon blinded about the study to record the modified healing index score of the wounds (range 0–6 points). For statistical analysis, we used the one-tailed t-test for paired samples with a significance level set at p < 0.05 to compare the baseline scores with those recorded during the exposure to the zinc–L-carnosine mouthwash. Results: The authors enrolled four women and six men (mean age = 44.60 ± 19.22 years). On the seventh and fourteenth postoperative days, the mean difference between the modified healing index scores obtained by using the zinc–L-carnosine mouthwash and the baseline was not significant. On the twenty-first postoperative day, the mean score obtained by using the mouthwash was 5.2 ± 1.3 points and was significantly higher than the 4.7 ± 1.8 points of the baseline (p = 0.026). On the twenty-eighth postoperative day, the mean difference was significant as well (5.9 ± 0.3 points and 5.4 ± 1.1 points, respectively). Conclusion: The preliminary results of this study showed that the zinc–L-carnosine mouthwash improved the quality of oral surgical wound healing.
