DeepTMH: Multimodal Semi-supervised framework leveraging Affective and Cognitive engagement for Telemental Health

To aid existing telemental health services, we propose DeepTMH, a novel framework that models telemental health session videos by extracting latent vectors corresponding to Affective and Cognitive features frequently used in psychology literature. Our approach leverages advances in semi-supervised learning to tackle the data scarcity in the telemental health session video domain and consists of a multimodal semi-supervised GAN to detect important mental health indicators during telemental health sessions. We demonstrate the usefulness of our framework and contrast against existing works in two tasks: Engagement regression and Valence-Arousal regression, both of which are important to psychologists during a telemental health session. Our framework reports 40% improvement in RMSE over SOTA method in Engagement Regression and 50% improvement in RMSE over SOTA method in Valence-Arousal Regression. To tackle the scarcity of publicly available datasets in telemental health space, we release a new dataset, MEDICA, for mental health patient engagement detection. Our dataset, MEDICA consists of 1299 videos, each 3 seconds long. To the best of our knowledge, our approach is the first method to model telemental health session data based on psychology-driven Affective and Cognitive features, which also accounts for data sparsity by leveraging a semi-supervised setup

Evaluation of root dentin damage during retreatment procedure using various engine-driven retreatment file systems—A micro-CT study

Aim: The aim of this research was to assess the damage to root dentin that arises from retreatment with different engine-driven NiTi retreatment files employing micro-computed tomography. Materials and Methods: Sixty mandibular premolar teeth having a single root and root canal that were recently extracted were gathered and stored. The specimens were de-coronated at the cementoenamel junction under water irrigation to achieve a homogeneous root length of 16 millimeters. Gutta-percha cones were coated with sealants and placed within the radicular canal till the WL. All sixty premolars were randomly assigned to one of the following three groups, with every group comprising 20 sample teeth each. Group 1: MTwo Retreatment files, Group 2: ProTaper Universal Retreatment files, Group 3: Edge File XR Retreatment rotary files. The quantity of root dentinal injury was estimated by deducting the dentin volume (mm3) in the pre- and post-therapy micro-CT scans at apical, middle, and cervical 3rd points. Results: An intra-group comparative scrutiny showed that lower radicular dentinal injury was noted at apical 3rd (0.31 ± 0.16, 0.62 ± 0.02) in Edge File XR Retreatment file system and MTwo Retreatment file system in that order. The statistically significant disparity was seen amid the MTwo Retreatment file, Edge File XR Retreatment file system and ProTaper Universal Retreatment file, Edge File XR Retreatment file system with P value of 0.001on intergroup assessment. Conclusion: In spite of the limitations that this research had, it was inferred that each assessed file system proficiently eradicated the obturated material through the retreatment procedure performed. In addition, it was seen that the Edge File XR group showed lesser root dentin damage in contrast to MTwo and ProTaper Universal file systems

Comparative assessment of changes in microflora in delayed and immediately placed implant: A clinical study

Aim of the present study was to assess the changes in microflora in delayed and immediately placed implant. In this study, a total of 30 implant areas in 30 patients were analyzed. The study group consists 14 male and 16 female participants in the age range of 20-40 years. The patients were randomly divided into two groups (15 patients in each group). Group A: Immediate Implant Placement, Group B: Delayed Implant Placement. Implant placement done accordingly. The materials and media used for the study were sterilized. One day before, sample collection and implant placement, complete mouth scaling, and polishing were done. Sites to be sampled were isolated with sterile cotton rolls. Bacterial culture media used in the study include blood agar, Kanamycin blood agar, and Kanamycin‑vancomycin blood agar. The samples were collected in the following stages- preoperative stage, After 24 hrs postoperative, After 7 days postoperative, on the day of prosthesis placement, 1st month follow‑up, 2nd month follow‑up. These following samples were tested to calculate the growth of the following pathogenic microorganisms: Aggregatibacter actinomycetemcomitans, Streptococcus, Porphyromonas gingivalis, Prevotella intermedia
