In dentistry, calculus or tartar is a form of hardened dental plaque. It is caused by precipitation of minerals from saliva and gingival crevicular fluid (GCF) in plaque on the teeth . This process of precipitation kills the bacterial cells within dental plaque, but the rough and hardened surface that is formed provides an ideal surface for ...
The non specific plaque hypothesis was introduced in the 1930s. Studies conducted were unable to identify a specific organism responsible for the formation of periodontal disease, and therefore was unable to support the specific plaque hypothesis. This new theory stated that all bacteria flora in plaque had a role in periodontal destruction ...
The Gompertz distribution is a flexible distribution that can be skewed to the right and to the left. Its hazard function = is a convex function of (;,).The model can be fitted into the innovation-imitation paradigm with = as the coefficient of innovation and as the coefficient of imitation.
Dental plaque is considered a biofilm adhered to the tooth surface. It is a meticulously formed microbial community, that is organised to a particular structure and function. [12] Plaque is rich in species, given the fact that about 1000 different bacterial species have been recognised using modern techniques. [13]
The following table compares general and technical information for a selection of common and uncommon Texas Instruments graphing calculators. Many of the calculators in this list have region-specific models that are not individually listed here, such as the TI-84 Plus CE-T, a TI-84 Plus CE designed for non-French European markets.
[2] [3] Life2vec is a transformer-based model, similar to those used in natural language processing (e.g., ChatGPT or Llama), trained to analyze life trajectories. The project leverages rich registry data from Denmark, covering six million individuals, with event data related to health, demographics, and labor, recorded at a day-to-day ...
The viscosity model for dilute gas, that is shown above, is widely used throughout the industry and applied science communities. Therefore, many researchers do not specify a dilute gas viscosity model when they propose a total viscosity model, but leave it to the user to select and include the dilute gas contribution.
Scaling and root planing, also known as conventional periodontal therapy, non-surgical periodontal therapy or deep cleaning, is a procedure involving removal of dental plaque and calculus (scaling or debridement) and then smoothing, or planing, of the (exposed) surfaces of the roots, removing cementum or dentine that is impregnated with calculus, toxins, or microorganisms, [1] the agents that ...
