Because of their resilience, Time-of-Flight (ToF) cameras are now essential components in scientific and industrial settings. This paper outlines the essential factors for modeling 3D ToF cameras, with specific emphasis on analyzing the phenomenon known as "wiggling". Through our investigation, we demonstrate that wiggling not only causes systematic errors in distance measurements, but also introduces periodic fluctuations in statistical measurement uncertainty, which compounds the dependence on the signal-to-noise ratio (SNR).

- The study aims to compare the effectiveness of heat-activated NiTi (HANT) wires to traditional NiTi wires in orthodontic alignment through a systematic review and meta-analysis.
- A comprehensive search was conducted up to January 2024 across various databases, including MEDLINE and Cochrane's CENTRAL, with a focus on clinical studies and risk assessment for bias.
- Results showed no significant differences in the effectiveness of both wire types regarding tooth alignment, pain intensity, or root resorption, suggesting that the choice of wire should consider patient and clinician preferences despite HANT wires potentially being more expensive.
Objective: To assess the effect of the toothbrush handle on video-observed toothbrushing behaviour and toothbrushing effectiveness.
Methods: This is a randomized counterbalanced cross-over study. N = 50 university students and employees brushed their teeth at two occasions, one week apart, using either a commercial ergonomically designed manual toothbrush (MT) or Brushalyze V1 (BV1), a manual toothbrush with a thick cylindrical handle without any specific ergonomic features.
