The management of salivary gland infection Essay

The management of salivary gland infection - Essay Example The management of these two types of salivary gland infection is possible with certain preventive measures and treatments. In certain cases, treatment is not required for curing these infections. The acute bacterial infection of the salivary glands occurs because of two important physiological mechanisms. Firstly, there are certain bacteria present in the oral cavity. Due to poor oral hygiene, the salivary duct and parenchyma tissue inhabited by these bacteria is contaminated which results in the infection. Secondly, the obstruction of salivary gland results in the stasis of salivary flow through the ducts and parenchyma promotes acute suppurative infection. The bacterial infection can affect any of the three pairs of the salivary glands however the most commonly affected gland is the Parotid gland. Several physiological and anatomic factors attribute to the predilection of the Parotid gland's infection. The composition of the Parotid gland secretion is completely different from that of the submandibular and sublingual glands. The saliva secreted by the Parotid gland is serous while that of the other two glands have higher proportion of mucinous material. The kind of saliva secreted by the other two glands contains lysosomes and IgA antibodies, which serve an antimicrobial function in protecting these glands from the bacterial infection. Mucins also contain sialic acid, which agglutinates bacteria, preventing its adherence to host tissues. Finally, specific glycoproteins found in mucins bind epithelial cells, competitively inhibiting bacterial attachment to these cells. There are certain anatomic factors as well that contribute to the p redilection of the parotid gland's infection. Stensen's duct lies adjacent to the upper mandibular molars, whereas Wharton's ducts rests on the floor of the mouth near the tongue. Tongue mobility may prevent salivary stasis in the area of warton's ducts, reducing the rate of infections involving the submandibular gland. The submandibular gland is more prone to bacterial infection rather than the sublingual gland in spite of its composition. Sialothiasis can produce mechanical obstruction of the duct, resulting in salivary stasis and subsequent bacterial infection. Calculus formation is associated frequently with acute bacterial infections of the submandibular gland because Wharton's duct is far more likely to harbor a calculus than stensen's duct.85 % to 90% of salivary calculi is located in the submandibular duct. Submandibular secretions are more mucinous than parotid secretions and therefore more viscid. They are also more alkaline containing a higher percentage of calcium phosphates. These characteristics contributes to the formation of submandibular calculi, despite the submandibular gland's predisposition for calculus formation. The parotid gland remains the most common site of acute suppurative salivary infection. Sialography, a method used for diagnosis of the internal structure of the salivary gland can also result in the infection of the submandibular glands rather than sublingual glands. There are small and numerous sublingual ducts which may not allow the catheter to enter unless there are anatomic variations.[ Bailey, Byron , Healy, Gerald ., Johnson, Jonas , Jackler, Robert , Calhoun, Karen , Pillsbury, Harold ,
