When looking at a cross section of the periodontium, which tissue is visible adjacent to the crown of the tooth?, Periodontal ligament, Gingiva, Cementum, Alveolar bone, A dental hygienist inserts a calibrated periodontal probe into a healthy sulcus until the tip reaches the base of the sulcus.

Which anatomical area of the gingiva is “missing,” resulting in the open spaces?, Attached gingiva, Interdental gingiva, Gingival sulcus, Interdental col, A dentist extracts a third molar tooth because it is crowding the adjacent teeth and is difficult for the patient to clean.

The interdental gingiva has one papilla on the facial and one papilla on the lingual., Both statements are true., Both statements are false., The first statement is true; the second is false., The first statement is false; the second is true., The depth of a clinically normal gingival sulcus is no greater than:, 1 mm., 3 mm., 5 mm., 7 mm., Which of the following is not a function of the periodontal ligament?, Suspends the tooth in its socket, Houses nerve endings that provide feeling to the tooth, Builds and maintains cementum, Prevents food from becoming packed in the sulcus, The interdental col is a space between the tooth surface and the free gingiva. It lies directly apical to the contact area., Both statements are true., Both statements are false., The first statement is true; the second is false., The first statement is false; the second is true., The periodontal ligament can remodel alveolar bone in response to pressure. The periodontal ligament contains blood vessels that provide nutrients to cementum and bone, Both statements are true., Both statements are false., The first statement is true; the second is false., The first statement is false; the second is true., Which tissue is a thin layer of yellow, hard, mineralized tissue that is attached to dentin of the root?, Alveolar bone, Cementum, Periodontal ligament, Enamel, Without cementum, the tooth would fall out of the socket. Cementum anchors the ends of periodontal ligament fibers to the tooth., Both statements are true., Both statements are false., The first statement is true; the second is false., The existence of alveolar bone is dependent on the presence of teeth. When teeth are extracted alveolar bone resorbs, Both statements are true., Both statements are false., The first statement is true; the second is false., The first statement is false; the second is true., Which of the following is not one of the layers of the alveolar process?, Alveolar bone proper, Cortical bone, Ramus, Cancellous bone, The lattice-like bone that fills the interior portion of the alveolar process is called the:, cortical bone., cancellous bone., periosteum., cribriform plate., The thin layer of bone that lines the socket that surrounds the root of the tooth is called the, cancellous bone., periosteum., alveolar bone proper., compact bone., The alveolar crest follows the contours of the cementoenamel junctions of teeth. In health, the alveolar crest covers the cementoenamel junctions of the teeth., Both statements are true., Both statements are false., The first statement is true; the second is false., The first statement is false; the second is true., The nerve supply to the periodontium is derived from branches of the _____________ nerve., transseptal, trigeminal, transoral, trigingival, Innervation of the teeth and periodontal ligament of the maxillary arch is from the _______ alveolar nerves, and innervation of the teeth and periodontal ligament of the mandibular arch is from the _______ alveolar nerves., superior, inferior, nasopalatine, buccal, infraorbital, mental, supramaxillary, inframandibular, Blood vessels can anastomose with nerves to create a vascular system that carries oxygen to tissues and feeling to the pulp of the tooth. The major function of the vascular supply is to carry carbon dioxide and other nutrients to tissues, Both statements are true., Both statements are false., The first statement is true; the second is false., The first statement is false; the second is true., Lymph from the periodontal tissues is drained to the lymph nodes of the:, armpits and neck., groin and head., head and neck., Dneck and groin., Which lymph nodes drain most of the periodontal tissues?, Deep cervical, Submental, Jugulodigastric, Submandibular, Which of the following is not filtered out by the lymph nodes?, Bacteria, Food debris, Fungi, Viruses, The width of attached gingiva is narrowest in which area?, Incisors, Canines, Premolars, Molars, Physiologic pigmentation appears:, light to dark coral pink., only in unhealthy gingiva., in anterior regions only., more frequently in dark-skinned people., Stippling is present in the majority of periodontally healthy individuals. Stippling is commonly observed on the free gingiva., Both statements are true., Both statements are false., The first statement is true; the second false., The first statement is false; the second true.
