| Examination of the oral cavity is part of every general physical examination. Oral findings in many systemic diseases are unique, are sometimes pathognomonic, and may be the first sign of the disease.

| A dental history is obtained first. It may indicate a particular dental problem or neglect of dental care. A complaint of difficulty in chewing food suggests insufficient teeth for proper mastication, loose or painful teeth, poorly fitting dental appliances, or disorders of the temporomandibular joint or the masticatory muscles. Slight bleeding after brushing suggests mild gingivitis; frequent, spontaneous, or profuse bleeding may indicate a blood dyscrasia. Recurring oral infections may indicate diabetes mellitus (the most common cause), agranulocytosis, neutropenia, leukemia, immunoglobulin defects, or disorders of leukocyte function. Immunosuppressed persons may experience painful reactivation of oral herpes simplex or other infections, with pain, oral ulcerations, and consequent interference with food intake.  | 首先采集å�£è…”ç§‘ç—…å�²,å�¯æ��示一个特别的å�£è…”问题或被忽略的å�£è…”ä¿�å�¥.主诉咀嚼食物困难æ��示能行使咀嚼功能的牙齿缺失或疼痛,或颞颌关节å�Šå’€åš¼è‚Œç¾¤åŠŸèƒ½ç´Šä¹±.刷牙å�Žè½»åº¦å‡ºè¡€,æ��示轻度牙龈炎;ç»�常的,自å�‘çš„,大é‡�出血,表示血液病.å��å¤�出现的å�£è…”感染,å�¯èƒ½å˜åœ¨ç³–尿病(æ¤ä¸ºæœ€å¸¸è§�åŽŸå› ï¼‰,粒细胞缺ä¹�ç—‡,䏿€§ç²’细胞å‡�å°‘ç—‡,白血病,å…�ç–«ç�ƒè›‹ç™½ç¼ºä¹�病或白细胞功能紊乱.å…�疫抑制者å�¯ç»�历å�£è…”å�•纯疱疹的疼痛å��应,并伴有å�£è…”溃疡而导致妨ç¢�摄食.   |

| The examiner initially looks at the face for appreciable asymmetry, skin lesions, and other abnormalities, such as restricted movement during speech, as occurs in scleroderma or acromegaly. Numerous congenital syndromes produce characteristic facies. For example, a very thin upper lip suggests the fetal alcohol syndrome or Prader-Willi syndrome. Trauma in youth, particularly blunt trauma to the point of the chin, can damage growth centers in the condyles and lead to unilateral or bilateral impairment of mandibular growth. Idiopathic hypertrophy of one or both sides of the mandible or other parts of the face may distort the face, as may acromegaly or a salivary gland or jaw tumor. If the posterior teeth or dental prostheses are missing, the cheeks may be sunken, producing a prematurely aged or cachectic appearance. One or both cheeks may appear swollen due to cherubism, parotitis, Sjögren's syndrome, tumor, an excessively thick denture flange, or cellulitis from an abscessed tooth. Multiple basal cell carcinomas on the face may indicate the nevoid basal cell carcinoma syndrome, which alerts the examiner to look for multiple odontogenic keratocysts on x-rays.  | 检查者首先观察é�¢éƒ¨æœ‰æ— 明显的ä¸�对称,皮肤病æ�Ÿå’Œå…¶ä»–çš„ä¸�æ£å¸¸,如当说è¯�æ—¶è¿�动å�—é™�常出现于硬皮病或肢端肥大症.许多先天性综å�ˆå¾�å�‡äº§ç”Ÿç‰¹æ®Šçš„é�¢è²Œ.例如,很薄的上唇æ��示胎儿酒精综å�ˆå¾�或Prader-Willi综å�ˆå¾�,é�’少年时期的创伤,特别是颊部的é’�伤,能伤å�Šé«�状çª�的生长ä¸å¿ƒå’Œå¯¼è‡´ä¸‹é¢Œéª¨å�•侧或å�Œä¾§ç”Ÿé•¿å�‘育å�—æ�Ÿ.下颌一侧或å�Œä¾§è‡ªå�‘性肥大,或é�¢éƒ¨å…¶ä»–部分自å�‘性肥大,如肢端肥大症或涎腺肿瘤或颌骨肿瘤å�‡å�¯ç ´å��é�¢éƒ¨å¤–貌.如果å�Žç‰™æˆ–义齿缺失,颊部会凹陷而形æˆ�æ—©è€�的或æ�¶ç—…è´¨æ ·çš„é�¢è²Œ.由于颌骨增大症,腮腺炎,SjÖgren综å�ˆå¾�,肿瘤,过厚的义齿çª�缘,或牙槽脓肿引致的蜂çª�织炎,å�‡å�¯ä½¿ä¸€ä¾§æˆ–å�Œä¾§é¢Šéƒ¨è‚¿èµ·.é�¢éƒ¨å¤šå�‘性基底细胞肉瘤å�¯è¡¨çŽ°ç—£æ ·åŸºåº•ç»†èƒžè‚‰ç˜¤ç»¼å�ˆå¾�,è¿™å�¯ä½¿æ£€æŸ¥è€…留心地在X线片上寻找多å�‘性牙æº�性角化囊肿.  |
| The lips are palpated. With the patient's mouth open, the buccal mucosa and vestibules are examined using a tongue blade; then the hard and soft palates, uvula, and oropharynx are viewed. The patient is asked to extend the tongue as far as possible, exposing the dorsum, and to move the extended tongue as far as possible to each side, so that its posterolateral surfaces can be seen. If a patient does not extend the tongue far enough for the circumvallate papillae to be seen, the examiner uses a gauze pad to grasp the tip of the tongue and extend it to the desired position. The tongue is then raised to view the ventral surface and the floor of the mouth. The teeth and gingivae should be viewed.  | 对唇部作扪诊,å�Œæ—¶ä»¤æ‚£è€…å¼ å�£,用舌æ�¿æ£€æŸ¥é¢Šç²˜è†œå’Œå�£è…”å‰�åºï¼›ç„¶å�Žå·¡æ£€ç¡¬è½¯è…,悬é›�垂和å�£å’½éƒ¨.请患者尽快地伸出舌,暴露舌背,并且尽快地å�‘æ¯�侧移动舌,è¿™æ ·å°±å�¯çœ‹åˆ°èˆŒçš„å�Žä¾§è¡¨é�¢.如果患者ä¸�能将舌伸出足够以使轮状乳头能被看è§�æ—¶,检查者å�¯ç”¨çº±å¸ƒåž«æ‹‰ä½�舌尖,使其伸出到所需的体ä½�.ç„¶å�Žå·¡æ£€èˆŒè…¹éƒ¨è¡¨é�¢å’Œå�£åº•,å†�检视牙齿和牙龈.  |
| With gloved hand, the examiner palpates the vestibules and the area over the roots of the teeth with one finger and the cheek with two fingers. The index finger of the dominant hand is inserted inside the mouth, and the contents of the floor of the mouth are compressed gently between it and the fingers of the other hand. To make palpitation more comfortable, the examiner asks the patient to relax the mouth, keeping it open just wide enough to allow access. The cervical lymph nodes should also be palpated.  | 检查者用戴手套的手指对å�£è…”å‰�åºè¿›è¡Œæ‰ªè¯Šå¹¶ç”¨ä¸€ä¸ªæŒ‡å¤´æ‰ªæ‰€æœ‰ç‰™é½¿çš„æ ¹éƒ¨,ç”¨ä¸¤ä¸ªæŒ‡å¤´æ ¸å¯¹.主检手的示指放入å�£å†…,å�¦ä¸ªæ‰‹çš„å‡ ä¸ªæ‰‹æŒ‡ç½®äºŽå�£å¤–相当部ä½�,轻柔地触扪å�£åº•.为了使扪诊更舒适些,å�¯è¯·æ‚£è€…å°†å�£è…”放æ�¾,ç»´æŒ�一定的开å�£åº¦ä»¥ä½¿æ‰‹æŒ‡èƒ½è¿›å…¥å�£è…”.对颈部淋巴结也应作扪诊.  |
| The temporomandibular joint (TMJ) is assessed by looking for jaw deviation during opening and by palpating the head of the condyle, anterior to the ear. The examiner then places his little fingers intrameatally while the patient opens widely and closes three times. The patient should be able to comfortably open wide enough to fit three fingers between the incisors. Trismus, the inability to open the mouth, may indicate scleroderma, arthritis, ankylosis of the TMJ, dislocation of the temporomandibular disk, tetanus, or tonsillar abscess. Unusually wide opening suggests subluxation or type III Ehlers-Danlos syndrome.  | 颞下颌关节(TMJ)的检查为当开å�£æ—¶åœ¨è€³å‰�方扪诊é«�状çª�的头,检视颌骨的å��å�‘.ç„¶å�Žæ£€æŸ¥è€…å°†å°�指深入置于外耳é�“内,è¯·æ‚£è€…å¼ å¤§å�£å’Œé—å�£3次.æ‚£è€…èƒ½èˆ’é€‚åœ°å¼ å¤§å�£,足以使上下切牙之间能放进三个手指.ä¸�èƒ½å¼ å�£çš„ç‰™å…³ç´§é—æ��示å�¯èƒ½ä¸ºç¡¬çš®ç—…,关节炎,颞下颌关节强直,颞下颌关节盘脱ä½�,ç ´ä¼¤é£Žæˆ–æ‰�桃体脓肿.异常的大开å�£æ��示关节盘å�Šè„±ä½�或Ehlers-Danlos综å�ˆå¾�的Ⅲ型(先天性é�—ä¼ æ€§ç»¼å�ˆå¾�,特å¾�为关节过度伸长,皮肤弹性脆弱ç‰---译者注).  |
| Malodor of exhaled breath may have many causes. Fetor oris originates in the mouth. Most commonly, it is caused by volatile sulfur compounds resulting from bacterial metabolism, particularly when oral hygiene is poor or xerostomia is present. Halitosis may follow eructation from the GI tract or may be caused by systemic metabolic conditions--eg, an acetone odor with diabetes mellitus, a mousy odor with liver failure, and a urinous odor with kidney failure. Halitosis may also originate from the nose, sinuses, nasopharynx, and lungs, particularly when infections or necrotic neoplasms are present. A patient whose breath frequently smells of mouthwash may be masking halitosis or may have parosmia (a perversion of the sense of smell, usually involving smelling unpleasant odors that do not exist).  | 呼å�¸æ°”味的æ�¶è‡å�¯ç”±è®¸å¤šåŽŸå› å¼•èµ·.å�£è‡èµ·æº�于å�£è…”.æœ€å¤šçš„åŽŸå› æ˜¯æ�¥è‡ªäºŽç»†è�Œä»£è°¢äº§ç”Ÿçš„æ˜“挥å�‘的硫化物,尤其是å�£è…”å�«ç”Ÿä¸�良或å�£å¹²ç—‡æ—¶.å�£è‡ä¹Ÿå�¯éš�èƒƒè‚ é�“的嗳气而æ�¥æˆ–由系统性代谢性疾病引起,也å�³ä¸™é…®å‘³ä¸Žç³–尿病有关,é¼ è‡å‘³ä¸Žè‚�åŠŸèƒ½è¡°ç«æœ‰å…³,å°¿å‘³ä¸Žè‚¾åŠŸèƒ½è¡°ç«æœ‰å…³.å�£è‡ä¹Ÿå�¯èµ·æº�于鼻部,上颌窦,鼻咽部和肺,尤其当这些部ä½�有感染或å��æ»æ€§è‚¿ç˜¤æ—¶.ç»�常散å�‘ç�€æ¼±å�£æ¶²æ°”æ�¯çš„æ‚£è€…常感觉有潜在的å�£è‡æˆ–å�¯èƒ½æ˜¯ä¸ªå—…觉倒错者(嗅觉å��常,常自己感到ä¸�适的è‡å‘³,而事实上æ¤å‘³æ˜¯ä¸�å˜åœ¨çš„).  |
