narrow banded worm
segmented parasite

Explanation:

1. Periodontitis, Rigg's disease, and periodontoclasia are all forms or aspects related to pyorrhea, which is an old - term for advanced gum disease. Gingivitis is an earlier stage of gum inflammation, tartar is a contributing factor to gum diseases, and scurvy is a vitamin - C deficiency disease not directly related to these.
2. The word "tapeworm" is derived such that it is a segmented parasite. It has a segmented body structure, which is a key characteristic. "Narrow banded worm" is not the correct literal definition, "parasitic worm" is a general term, and "long host" is not relevant to the definition of tapeworm.

Answer:

1. pyorrhea
2. segmented parasite
