RESUMEN
BACKGROUND: The study compared the clinical effectiveness of topical Tacrolimus (TAC) in patches or gel with Triamcinolone acetonide (TRI) gel for erosive/atrophic oral lichen planus (OLP) and investigated the influence of these therapies on Caspase-3 expression as a marker of apoptosis. METHODS: Thirty patients were randomly assigned into three equal groups to receive either topical TAC 0.1% patch twice daily, topical TAC 0.1% gel, or topical TRI 0.1% gel four times daily for 8 weeks. Each patient's clinical score (CS), visual analogue scale (VAS), and total atrophic area (TAA) of the marker lesion were measured at baseline, 2, 4, and 8 weeks of treatment, as well as after 4 weeks of treatment free period. Caspase-3 expression and lymphocytic counts (LC) were assessed in pre- and post-treatment biopsied stained sections. RESULTS: TAC patch resulted in a higher reduction in CS [- 14.00 (15.54%)] and VAS [- 70.21 (15.82%)] followed by TAC gel then TRI gel within the first two weeks. The reduction in VAS and TAA were significantly higher in TAC groups compared to TRI gel, although the difference between TAC treatment was not significant and this was observed throughout the treatment and follow-up periods. Caspase-3 expression increased in connective tissue in all groups. It decreased significantly within the epithelium in both TAC groups but increased in TRI gel. (LC) were significantly lowered with the TAC patch compared to other groups. The percentage change in Caspase-3 epithelial expression was significantly correlated to the CS, TAA, and LC. CONCLUSION: Both TAC patch and gel significantly decreased pain and lesion size than TRI gel, with a significant reduction in Caspase-3 expression within the epithelium in comparison to the increase seen with TRI gel. The study protocol was registered at www. CLINICALTRIALS: gov (NCT05139667) on 01/12/2021.

BACKGROUND: This study aimed to evaluate the effect of oral glutamine suspension on salivary levels of transforming growth factor beta 1 (TGF-ß1), a cytokine involved in inflammation and Tumor progression, and the severity of radiation-induced oral mucositis (RIOM) in head and neck cancer patients. This is the first study to investigate the impact of glutamine on TGF-ß1 levels in head and neck cancer patients with radiation induced oral mucositis (RIOM). METHODS: In this randomized controlled clinical trial, 50 HNC patients were enrolled and received either glutamine oral suspension or maltodextrin as a placebo from the baseline of RIOM to the end of radiotherapy. Salivary TGF-ß1 levels were measured at baseline and after treatment. Also, RIOM was assessed using the World Health Organization (WHO) Oral Toxicity Scale, the Oral Mucositis Assessment Scale (OMAS), the Pain Visual Analog Scale (Pain-VAS), the incidence of opioid use, and body mass index (BMI). RESULTS: Glutamine significantly reduced salivary TGF-ß1 levels and improved RIOM symptoms, such as pain, opioid use, and weight loss. The reduction of TGF-ß1 levels was associated with the improvement of RIOM severity. CONCLUSION: Glutamine may modulate the inflammatory response and enhance wound healing in RIOM by decreasing salivary TGF-ß1 levels. These findings support the use of glutamine as a potential intervention for RIOM and nutritional support for improving radiation sensitivity. TRIAL REGISTRATION: This study was registered on clinicalTrials.gov with identifier no. NCT05856188.

BACKGROUND: Taking into consideration the value of the oral health condition in geriatric people with end-stage renal disease (ESRD) associated with xerostomia and believing that salivary stimulants or substitutes could potentially be used to manage this condition. This study aimed to evaluate the clinical effectiveness of thyme honey as oral rinse in geriatric patients with ESRD using the subjective dry mouth score as a primary objective and to assess the effect of thyme honey on the salivary nitric oxide level, salivary flow rate, and salivary ph in addition to objective dry mouth score as a secondary objective. METHODS: This was a single blinded randomized controlled trial with two equal arms, the interventional arm (thyme honey oral rinse) and the control arm (saline). Twenty-eight geriatric patients with ESRD undergoing hemodialysis complained of xerostomia were recruited from the renal dialysis center. Patients in both arms followed the same administration protocol either with thyme honey oral rinse or saline. The following clinical parameters (the subjective and objective dry mouth scores, salivary flow rate, salivary ph, and salivary nitric oxide (NO) levels) were evaluated for both groups at different intervals (baseline, 1 week, and 1 month). RESULTS: In the current study, it was found that both the subjective and objective dry mouth scores were significantly lower after one month of using thyme honey oral rinse (1.86 ± 0.66B) and (2.21 ± 0.43B) respectively, than the control group (3.07 ± 0.73B) and (3.07 ± 0.83B), respectively with a (p < 0.001). Also, the salivary flow rate was significantly higher after one month of using thyme honey oral rinse (1.56 ± 0.51A), than the control group (0.78 ± 0.27A) with a (p < 0.001). For the NO levels, there was a significant increase in measured value after 1 month in the intervention group (p < 0.001), while for the control group the change was not statistically significant (p = 0.166). CONCLUSIONS: The results of the current study have revealed the efficacy of Thyme honey oral rinse in the management of xerostomia in geriatric patients with ESRD. Trial registration The ClinicalTrials.gov Identifier for this study is NCT05247008.

OBJECTIVE: To investigate the effectiveness of pimecrolimus treatment in patients not responding to corticosteroid treatment and to investigate its effect on Fas expression on keratinocytes in oral lichen planus (OLP). SUBJECTS AND METHODS: Twenty patients with OLP were recruited from the Oral Medicine Clinic at the School of Dentistry, Ain Shams University, Egypt. Pimecrolimus 1% cream with a hydrophilic adhesive gel base was applied to the oral lesions, four times daily, for a total of 2 months. A marker lesion was identified and assessed by clinical scoring (CS). The symptomatology score was obtained using a visual analog scale (VAS). Pre-treatment and post-treatment specimens were immunohistochemically stained for detecting Fas. RESULTS: The results of clinical scores showed statistically high significant improvement (P = 0.0001). The mean VAS decreased significantly over time as well as the mean of Fas expression (P < 0.05). The overall percentage of reduction from baseline to week 8 was 87%, 93%, and 67% for clinical scores, visual analog score, and Fas expression, respectively. CONCLUSIONS: Topical pimecrolimus reduced Fas expression, and it appears to be a promising alternative treatment for OLP.

The purpose of this study was to assess the prevalence and associated factors of dental caries and periodontal diseases among 14â»19-year-old schoolchildren with limited access to dental care services. A cross sectional study design was conducted during field visits to seven governmental schools in Al-Khomrah district, South Jeddah, over the period from September 2015 to May 2016. Clinical examinations and administered questionnaires were carried out in mobile dental clinics. The dentists carried out oral examinations using the dental caries index (DMFT), the simplified oral hygiene index (OHI-S), and the community periodontal index for treatment needs (CPITN). Statistical analyses were performed using SPSS 20. A total of 734 schoolchildren were examined. The prevalence of decayed teeth was 79.7% and was significantly higher among boys (88.9%) than girls (69.0%). About 11% of students had missing teeth, with a significantly higher figure among females than males (15.9% versus 7.3%); 19.8% of students had filled teeth. Moreover, a DMFT of seven or more was significantly more prevalent among males (43.3%) than females (26.8%), while the percentage of females with sound teeth was significantly higher than for males (20.4% and 9.6% respectively). The CPITN revealed 0, 1 and 2 scores among 14.6%, 78.2%, and 41.6% respectively. Males had a significantly higher percentage of healthy periodontal condition (23.8%) than females (3.8%). Dental caries prevalence was moderate to high, calculus and gingival bleeding were widespread among schoolchildren, and were more prevalent among students with low socioeconomic status.
RESUMEN
Objective: To evaluate the awareness of medical emergencies among dental practitioners in three dental schools. Material and methods: The study group included 384 dental practitioners, including dental staff members, post-graduate students, and dental interns. These professionals were attending three dental educational institutions in Egypt. Two of them were governmental and one was a private school. The educational model is almost the same in most Egyptian dental schools. Results: The response rate was 100%. Most of the participants worked in private academia (44.16%) or practice (42.34%) and 65.20% of them were females. The participants who recorded the medical history and filled a form (91.17%, 80.52 % respectively) while only 41.82% obtained the vital signs. Among the participants, 48.57 % were confident about handling medical emergency and 74.29 % reported their capability of intramuscular injection while only 25.71 % for intravenous injection and 49.35% knew about emergency kits. Management knowledge of airway obstruction and prosthetic heart valve patients was reported by 80.27 % and 71.94 % respectively, while less percentage for activation of EMS, chest compression, CPR ratio, and infant rescue breathing. The mean preparedness percent score was 54.57% and it was inversely correlated to the years of experiences and directly correlated to the degree of confidence in their ability to manage the dental emergency. Conclusion: The current study results reflected a deficiency in the dental practitioner awareness about the medical emergency especially the practical part. (AU)
Objetivo: Avaliar a consciência das emergências médicas entre os dentistas de três faculdades de odontologia. Material e Métodos: O grupo de estudo incluiu 384 dentistas, abrangendo membros da equipe odontológica, alunos de pós-graduação e estagiários de odontologia. Esses profissionais frequentavam três instituições de ensino de odontologia no Egito. Duas eram governamentais e uma era uma instituição particular. O modelo educacional é similar na maioria das escolas de odontologia egípcias. Resultados:A taxa de resposta foi de 100%. A maioria dos participantes trabalhava na área acadêmica (44,16%) ou clínica privadas (42,34%) e 65,20% deles eram do sexo feminino. Os participantes registraram o histórico médico e preencheram um formulário (91,17%, 80,52% respectivamente) enquanto apenas 41,82% obtiveram os sinais vitais. Entre os participantes, 48,57% estavam confiantes para lidar com emergências médicas e 74,29% relataram sua capacidade de injeção intramuscular, enquanto apenas 25,71% para injeção intravenosa e 49,35% sabiam sobre kits de emergência. O conhecimento do manejo de pacientes com obstrução das vias aéreas e válvula cardíaca protética foi relatado por 80,27% e 71,94%, respectivamente, enquanto menos porcentagem para a ativação do serviço de emergência médica (SEM), compressão torácica, índice de reanimação cardiorrespiratória (RCP) e respiração de resgate infantil. A pontuação percentual média de preparação foi de 54,57% e foi inversamente correlacionada aos anos de experiência e diretamente correlacionada ao grau de confiança em sua capacidade de gerenciar a emergência odontológica. Conclusão: Os resultados do presente estudo refletiram uma deficiência na conscientização do dentista sobre a emergência médica principalmente a parte prática (AU)
