Lichen sclerosus et atrophicus manifesting with localized loss of periodontal attachment.

Lichen sclerosus et atrophicus (LSA) is a chronic mucocutaneous inflammatory disorder of uncertain aetiology that is clinically characterized by the appearance of well delimited white plaques or papules, preferentially affecting the skin and genitals, and more rarely the oral cavity. We present the case of a woman with LSA limited to the oral cavity in the form of a well delimited, flat whitish lesion affecting the vestibular gingiva of the right upper incisors and left central incisor, and extending towards the vestibular fundus and frenulum of the upper lip. Widening of the periodontal space was observed, with gingival recession and attachment loss limited to these teeth. Local corticosteroid injections caused the mucosal lesion but not the periodontal alterations to resolve. Emphasis is placed on the importance of knowledge of this condition in relation to establishing a diagnosis, and on its periodontal repercussions.

Renal hemodialysis patients: oral, salivary, dental and periodontal findings in 105 adult cases.

OBJECTIVES: A study of the dental, periodontal, oral mucosal and salivary condition of adult patients with chronic renal failure (CRF) receiving hemodialysis (HD). MATERIAL AND METHODS: A total of 105 patients on HD were studied, together with 53 healthy age and sex-matched controls. Indices employed included carious, absent and obturated teeth index (CAO index), plaque index, calculus index and loss of periodontal attachment. Whole and parotid salivary secretions were also measured. RESULTS: The CAO index was not significantly higher among HD patients than controls (14.9 +/- 8.7 vs 13.3 +/- 7.9, respectively; t = 1.1; P = 0.3). However, plaque and calculus indices were significantly higher in HD patients (2.1 +/- 0.8 and 2.3 +/- 0.6, respectively) than controls (1.3 +/- 0.8 and 1.6 +/- 0.9) (P < 0.001). Loss of periodontal attachment was similar in both groups (4.9 +/- 2.5 vs 4.2 +/- 2.5 in the HD patients and controls, respectively) (t = 1.8; P = 0.07). There was no more oral mucosal pathology in HD patients than in controls (chi-square = 5.8; P = 0.3). Stimulated salivary secretion was significantly higher in controls than HD patients for both whole (t = -5.2; P < 0.001) and parotid (t = -2.6; P = 0.01) salivas. CONCLUSIONS: The results show significantly higher plaque and calculus indices and lower salivary secretion among the HD patients than in healthy controls.

Peripheral ameloblastoma.

A 73-year-old male ex-smoker of 10 cigarettes/day (up until 10 years ago) with a history of hypertension treated with Diovan 80 (Valsartan) was referred by his dentist. For the past 6 months the patient has presented an ulcer located in the right retromolar trigone region. In the last 2 months the patient has used chlorhexidine rinses, and is not wearing his dentures; the lesions fail to heal, however. Intraoral examination showed an ulcer in the right retromolar trigone area (Fig. 1-2), with a fibroelastic consistency. No regional lymph nodes were palpable. A panoramic X-ray study (Fig. 3), biopsy (Fig. 4-6) and CT exploration were requested.
