This has led to the popular belief that necrotizing gingivitis is contagious, but this is not the case. The main features of necrotizing gingivitis are painful, bleeding gums and ulceration and necrosis of the interdental papilla. There may also be intra-oral halitosis, cervical lymphadenitis (swollen lymph nodes in the neck) and malaise.
Interdental papillae are ulcerated with dead tissue. [3] The papillary necrosis of NG has been described as "punched out". [2] Other signs and symptoms may be present, but not always. [2] Foul breath. Bad taste (metallic taste). [3] Malaise, fever and/or cervical lymph node enlargement are rare (unlike the typical features of herpetic ...
The interdental papilla, also known as the interdental gingiva, is the part of the gums (gingiva) that exists coronal to the free gingival margin on the mesial and distal surfaces of the teeth. The interdental papillae fill in the area between the teeth apical to their contact areas to prevent food impaction; they assume a conical shape for the ...
The milder form, necrotizing ulcerative gingivitis (also termed "trench mouth"), [9] is characterized by painful, bleeding gums and ulceration and necrosis of the interdental papilla. There may also be intra-oral halitosis , cervical lymphadenitis (swollen lymph nodes in the neck) and malaise .
The pain is deep and throbbing. The oral mucosa covering an early periodontal abscess appears erythematous (red), swollen and painful to touch. [3] The surface may be shiny due to stretching of the mucosa over the abscess. Before pus has formed, the lesion will not be fluctuant, and there will be no purulent discharge. There may be regional ...
The interdental gum lies between the teeth. They occupy the gingival embrasure, which is the interproximal space beneath the area of tooth contact. The interdental papilla can be pyramidal or have a "col" shape. Attached gums are resistant to the forces of chewing and covered in keratin.
Outside of the mouth, the sinuses, muscles of the face and neck, the temporomandibular joints, and cervical lymph nodes are palpated for pain or swelling. [10]: 9 In the mouth, the soft tissues of the gingiva, mucosa, tongue, and pharynx are examined for redness, swelling or deformity. Finally, the teeth are examined.
The interdental papilla does not fully enclose the space, leading to an aperture between adjacent teeth. [1] This gap has many causes including gingival recession, and gingival withdrawal post-orthodontic work. [2] Interdental "black triangles" were rated as the third-most-disliked aesthetic problem below caries and crown margins. [3]
