Avalanche Problems
There are nine different types of avalanche problems:
Storm slab
Wind slab
Wet slab avalanches
Persistent slab
Deep persistent slab
Loose dry avalanches
Loose wet avalanches
Glide avalanches
Cornice fall

Canadian classification for avalanche size
The Canadian classification for avalanche size is based upon the consequences of the avalanche. Half sizes are commonly used. United States classification for avalanche size
The size of avalanches are classified using two scales; size relative to destructive force or D-scale and size relative to the avalanche path or R-scale. Both size scales range from 1 to 5 with the D size scale half sizes can be used. Rutschblock Test
Slab avalanche hazard analysis can be done using the Rutschblock Test. A 2 m wide block of snow is isolated from the rest of the slope and progressively loaded. The result is a rating of slope stability on a seven step scale. (Rutsch means slide in German). Avalanches and climate change
Avalanche formation and frequency is highly affected by weather patterns and the local climate. Snowpack layers will form differently depending on whether snow is falling in very cold or very warm conditions, and very dry or very humid conditions. Thus, climate change may affect when, where, and how often avalanches occur, and may also change the type of avalanches that are occurring. Impacts on avalanche type and frequency
Overall, a rising seasonal snow line and a decrease in the number of days with snow cover are predicted.

Chronic periapical periodontitis
Chronic (or asymptomatic) periapical periodontitis. Related lesions
In addition to periapical abscesses, periapical periodontitis can give rise to various related lesions, including periapical granulomas and cysts. A periapical granuloma (also referred to as an apical granuloma or radicular granuloma) is a mass of chronically inflamed granulation tissue that forms at the apex of the root of a nonvital (dead) tooth. (Although not a true granuloma, given the absence of granulomatous inflammation, the term periapical granuloma is widely accepted.) Treatment
Treatment options may include antibiotic therapy (in the short term, augmented by chewing gum), root canal therapy, or extraction. Epidemiology
Periapical periodontitis of some form is a very common condition. The prevalence of periapical periodontitis is generally reported to vary according to age group, e.g. 33% in those aged 20–30, 40% in 30- to 40-year-olds, 48% in 40- to 50-year-olds, 57% in 50- to 60-year-olds and 62% in those over the age of 60. Most epidemiologic data has been generated in European countries, especially Scandinavia. While millions of root canal treatments are carried out in the United States alone each year, total numbers of such cases do not provide reliable indicators of frequency, even for symptomatic periapical periodontitis (given that root canal treatment is not always indicated or complied with, and may also be performed in the absence of periapacial periodontitis).
