References此疾病可以單獨出現，也可能是某些更廣泛健康問題（如維生素 B12 或鐵缺乏所致貧血）或局部感染（如皰疹、口腔念珠菌病）的一部分。唇炎亦可能因對刺激性或過敏性物質的反應而發生，或由陽光（actinic cheilitis）或某些藥物（尤其是類維生素A）引起。已報告的唇炎形式包括：angular、contact（allergic and irritant）、actinic、glandular、granulomatous、exfoliative 以及 plasma cell cheilitis。
The disease may appear as an isolated condition or as part of certain systemic diseases/conditions (such as anemia due to vitamin B12 or iron deficiency) or local infections (e.g., herpes and oral candidiasis). Cheilitis can also be a symptom of a contact reaction to an irritant or allergen, or may be provoked by sun exposure (actinic cheilitis) or drug intake, especially retinoids. Generally, the forms most commonly reported in the literature are angular, contact (allergic and irritant), actinic, glandular, granulomatous, exfoliative and plasma cell cheilitis.

口角炎相當常見，估計影響約 0.7% 的人口，最常見於 30 歲至 60 歲的成人，兒童中亦相對常見。
口角炎可由感染或刺激引起，感染源包括真菌與細菌。在發展中國家，缺鐵或維生素缺乏亦可能是成因。
○ 治療 - 非處方藥
將非處方抗生素軟膏塗抹於病變部位，每日兩次，持續數天。嘴唇反覆出現的濕疹常是嘴唇乾裂的主要原因，同時治療濕疹可預防復發。在已開發國家，營養不良較少成為原因。
