Teledentistry is an examination and consultation of patients to the dentist without going through face-to-face visits, but with the help of an online application. The purpose of the activity is to help and facilitate Co-ass students of the Faculty of Dentistry, Andalas University, to fulfill the requirements for oral diagnosis via online (teledentistry) during the covid 19 pandemic. The activity is carried out in the form of examination/screening of patients carried out by Co-ass students whom Hospital Precept accompanies at the Faculty of Dentistry, Andalas University (Lecturer). Activities to be carried out consist of counseling, coordinator, mentoring, and monitoring of implementation and evaluation. The results of this activity can meet the patient's need for dental and oral examinations and expand access to dental care. Dental and oral health is essential for every individual, especially for carrying out functions such as eating, speaking, aesthetics, and feeling comfortable throughout the day. The Covid-19 pandemic limits the community's social conditions, including their need to get dental and oral services from dentists. In addition, dentistry is one of the jobs most at risk of contracting Covid-19 from patients. Through teledentistry activities, a dentist takes anamnesis to patients, clinical examinations are carried out through consultation through pictures and videos, diagnosis as initial information in planning further treatment, and supportive care such as patient education.

Background: Gingivitis in stunted children represents a unique pathological entity driven by a compromised mucosal barrier and systemic zinc deficiency. These children exhibit a phenotype of acquired immunodeficiency, where standard mechanical debridement often fails to resolve inflammation, leading to a phenomenon known as dysbiotic rebound. This study investigated the biomolecular efficacy of systemic Zinc supplementation combined with scaling and root planing (SRP) in modulating the oral microbiome of nutritionally vulnerable children. Methods: A randomized, single-blind, pre-post test controlled clinical trial was conducted in Padang, Indonesia, involving 30 stunted children (Height-for-age Z-score < -2 SD) diagnosed with generalized gingivitis. Participants were randomized into a Control group (SRP + Placebo, n=15) and an Intervention group (SRP + 20mg Zinc Sulfate Monohydrate daily, n=15) for a duration of 14 days. Microbial profiling was performed on unstimulated saliva utilizing high-throughput 16S rRNA gene sequencing (V3–V4 region). Bioinformatics processing utilized the DADA2 pipeline to generate Amplicon Sequence Variants (ASVs). Results: Results indicated that SRP alone resulted in a pathogenic recolonization dominated by Firmicutes (+49.6%). Conversely, Zinc supplementation induced a significant Gram-negative crash, reducing Proteobacteria by 50.6%. Most notably, the key periodontal pathogen Prevotella was suppressed to undetectable levels in the Zinc group (p<0.05). Conclusion: Systemic zinc acts as a potent biological scaffold in the enterosalivary cycle, likely repairing the epithelial barrier and starving hemin-dependent pathogens. It is strongly recommended as a therapeutic adjuvant to prevent the ecological recurrence of gingivitis in nutritionally vulnerable pediatric populations.
