histological status, periodontal health

In the fabrication of any fixed prosthesis, it is very important to determine the — and — of the involved abutment tooth

biological width

preservation of the health of the dental tissues, especially the —, is one of the critical aspects in tooth restoration

calcified tissues

these are the hard tissues/ structures of the oral cavity

enamel

a calcified tissue composed primarily of carbonate substituted hydroxyapatite crystallites

carbonate substituted hydroxyapatite crystallites

enamel is a calcified tissue composed primarily of —

amelogenesis

the process of enamel development is called —

ameloblasts

the cells that create enamel are —

oral ectoderm

ameloblasts are derived from the —

dentin

a calcified tissue that is the main supporting structure of the tooth and is the second hardest tissue in the body after enamel

70% mineral and acellular (as hydroxyapatite crystals), 30% organic (as water, collagen and mucopolysaccharide)

dentin is composed of — and —

cementum

a calcified tissue that is a hard layer of tissue that helps the periodontal ligament attach firmly to a tooth

cementoblasts

cells that form cementum

cementum

a calcified tissue that slowly forms over a lifetime

cementum

is a hard, calcified layer of tissue that covers the root of the tooth

periosteum, dense compact bone, cancellous bone, cribriform plate

alveolar bone is consists of four layers:

cribriform sockets

The fourth layer of alveolar bone, which lines the alveolar sockets

lamina dura

Radiographically, cribriform plate appears as a fine radiodense line called the—

pulp

is a mass of connective tissue that resides within the center of the tooth, directly beneath the layer of dentin

endodontium

referred to as part of the dentin-pulp complex also known as —, these two tissues are closely interrelated and dependent on each other’s development and survival

periodontal ligaments

is a soft connective tissue embedded between the cementum and the inner wall of the alveolar bone socket to help support teeth

stem cells

periodontal ligament harbors a small population of — that are responsible for maintaining and repairing periodontal ligament tissues and function

gingiva

is the tissue that surrounds and protects the teeth and underlying bone

seal

the gingiva is attached to the tooth, forming a — that protects the underlying bone and helps provide a barrier against infection
