| 释义 |
Salivary gland aplasia (also termed salivary gland agenesis) is the congenital absence of salivary glands. Usually the term relates to the absence of some or all of the major salivary glands. It is a rare condition, and most known cases have been in association with syndromes of the ectodermal tissues,[1] particularly the lacrimal apparatus.[2] Example syndromes which have been reported with salivary gland aplasia include hereditary ectodermal dysplasia, mandibulofacial dysostosis and hemifacial microsomia.[1] The main significance of the condition is a lack of saliva, causing xerostomia (dry mouth), with accompanying susceptibility to dental caries (tooth decay), infections of the mouth,[2] and upper respiratory tract infections (e.g., candidiasis, ascending sialadenitis, laryngitis and pharyngitis).[3] Patients with salivary gland aplasia typically require regular application of topical fluoride to prevent tooth decay.[1] References1. ^1 {{cite book|author=Purkait SK|title=Essentials of Oral Pathology|url=https://books.google.com/books?id=fDRtoGmVGQQC&pg=PA199|year=2011|publisher=JP Medical Ltd|isbn=978-93-5025-214-7|page=199}} {{Oral pathology}}2. ^1 {{cite journal|last1=Taji|first1=SS|last2=Savage|first2=N|last3=Holcombe|first3=T|last4=Khan|first4=F|last5=Seow|first5=WK|title=Congenital aplasia of the major salivary glands: literature review and case report.|journal=Pediatric Dentistry|date=2011|volume=33|issue=2|pages=113–8|pmid=21703060}} 3. ^1 {{cite journal|last1=Kwon|first1=SY|last2=Jung|first2=EJ|last3=Kim|first3=SH|last4=Kim|first4=TK|title=A case of major salivary gland agenesis.|journal=Acta Oto-Laryngologica|date=February 2006|volume=126|issue=2|pages=219–22|pmid=16428204|doi=10.1080/00016480500314139}} 1 : Salivary gland pathology |
