INTRODUCTION: The quick spread of COVID-19 has caused part of the world's population to adopt quarantine protocols that have limited professional activities, including dental training programmes. This study aimed to explore the experiences of students and personnel at a Chilean dental school during the COVID-19 pandemic. MATERIALS AND METHODS: This phenomenological descriptive qualitative study reported staff and students' experiences during the pandemic through in-depth, semi-structured interviews. These were recorded on audio and video with a digital platform. Three researchers then transcribed and analyzed the recordings and codified the answers into categories to determine the emerging topics until a saturation point was reached. RESULTS: The core emerging themes among the staff group were (1) change in the personal/professional life balance, (2) online learning through digital platforms, (3) staff perceptions of students' learning experiences, and (4) concerns about the future. For students, the themes were (1) changes in the learning process, (2) online learning through digital platforms, (3) interpersonal relationships, and (4) concerns about the future. CONCLUSION: The COVID-19 pandemic has been a period of learning for our dental school staff and students. Even though online learning has been a useful tool for delivering didactic (theoretical) concepts, it has been unable to replace conventional education, including skills training. Students and teachers reported being overwhelmed at the beginning of the pandemic, but they have shown remarkable adaptability and resilience during this period.

AIM: To evaluate the impact of two non-surgical periodontal treatment modalities on metabolic and periodontal clinical parameters in subjects with type 2 diabetes mellitus (T2DM) and poor glycaemic control and chronic periodontitis. MATERIAL AND METHODS: A randomized controlled clinical trial was conducted. Ninety-three T2DM subjects with glycosylated haemoglobin (HbA1c) > 7% were randomly assigned to one of two groups receiving scaling with root planing in multiple sessions quadrant-by-quadrant (Q by Q) or within 24 hr (one stage). Periodontal parameters, HbA1c, glycaemia blood levels (FPG) and C-reactive protein (CRP) values were assessed at baseline and at 3 and 6 months post-therapy. RESULTS: At 6 months, HbA1c had decreased by 0.48% in the Q by Q group and by 0.18% in the one-stage group (p = 0.455). After therapy, subjects with an initial HbA1c < 9% showed an increase of 0.31% (p = 0.145), compared with a decrease of 0.88% (p = 0.006) in those with an initial HbA1c ≥ 9%. Periodontal parameters improved significantly (p < 0.0001) post-therapy, with similar results for both treatment modalities. CONCLUSION: Periodontal therapy had the greatest impact on HbA1c reduction on patients with an HbA1c > 9% regardless of treatment modality. Both modalities resulted in significant improvements in periodontal parameters.
