Injectable platelet rich fibrin effect on laser depigmented gingiva: a clinical randomized controlled split mouth trial with histological assessment

Abstract Objective To determine whether intra-mucosal injection of injectable platelet-rich fibrin (i-PRF) can promote healing after Diode Laser Gingival Depigmentation (DLGD). Methodology A total of 20 arch sites of hyperpigmented gingiva of 10 patients underwent DLGD. For each patient, two arch sites were randomly assigned for either intra-mucosal injection of i-PRF (G1-i-PRF) (n=10 sites) or no treatment (G2-Control): (n=10 sites). Wound Healing Score (WHS), patient satisfaction, and Pigmentation Index (DOPI) were measured at 1 week and 1 and 3 months postoperatively. Histological assessment of tissue specimens was performed at baseline and 1 week. Results The percentage change in WHS at 1 week was significantly higher in G1 (58.34±15.43) compared to G2 (37.50±11.79). At day 1, 50% of patients in G1 were pain free compared with 75% in G2, who had mild pain. Mean DOPI decreased significantly at 3 months in both groups (P-value <0.001), without significant differences between groups. G1 specimens showed significantly higher epithelial thickness (P-value <0.001), as well as a higher number of blood vessels and less percentage of inflammatory cells. Conclusions i-PRF demonstrated better clinical and histological healing potential and less patient discomfort compared to sites without treatment after DLGD.

Awareness of medical emergencies among dental practitioners in three Egyptian dental schools: A cross-sectional study / Conscientização sobre emergências médicas entre dentistas em três Faculdades de Odontologia Egípcias: um estudo transversal

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)

Oral Health Status and Habits among 6 - 13 Years Old Children with Limited Access to Dental Care in South Jeddah

The objective of this research was to assess oral health status and habits and to explore potential risk factors for dentalcaries among 6-13 years old children with limited access to dental care. A cross-sectional design was used to screen asample of 563 intermediate school children with limited access to oral health care in the Al-Khomrah district, south Jeddah,Saudi Arabia. A stratified random sample was selected and data was collected using an interview questionnaire withextraoral and intraoral examination. The examination aimed at detection of oral health conditions regarding oral hygienestatus, habits, decayed, missing and filled teeth and treatment needs. Treatment of simple and emergency cases wasperformed in the mobile clinic and severe cases were referred to King Abdulaziz University, Faculty of Dentistry (KAUFD).The study included 262 males (46.5%) and 301 females (53.3%) with a mean age of 10.99 + 2.07 years. The prevalence ofdecayed, missing or filled primary teeth was 59.1%, 2.5%, and 3.4%, respectively. The corresponding values for permanentteeth were 65.9%, 4.3% and 7.6%, respectively. Males had significantly higher prevalence of caries than females. Theyounger age groups, in case of primary teeth and the older age groups, in case of permanent teeth had significantly higherprevalence of dental caries. The median dmft (95% CI) was 2 (1-2) and the median DMFT (95% CI) was 2 (2-3).Multinomial multiple logistic regression indicated that intensity of primary teeth caries decreased with increasing age andbrushing teeth at least once a day and increased with male gender, living in rented house or having poor oral hygiene. Asregards permanent teeth, the likelihood of having more severe caries increased by child’s age, below secondary schooleducated fathers and/or mothers, being a male, and with poor oral hygiene. Dental caries prevalence and intensity weremoderate among the examined group. Males had significantly higher caries prevalence and intensity than females.
