Orofacial granulomatosis: clinical features and long-term outcome of therapy.

BACKGROUND: Orofacial granulomatosis (OFG) is a chronic inflammatory disorder characterized by persistent or recurrent soft tissue enlargement, oral ulceration, and a variety of other orofacial features. There remain few detailed reports of the clinical features and long-term response to therapy of substantial groups of patients with OFG. OBJECTIVE: The aim of this study was to determine retrospectively the clinical, hematologic, and histopathological features of a large case series of patients with OFG. In addition the long-term response to therapy was examined. METHODS: Clinically relevant data of 49 patients with OFG who attended a single oral medicine unit in the United Kingdom were retrospectively examined. The analyzed parameters included diagnostic features, clinical manifestations, and outcomes and adverse side effects of therapy. RESULTS: Labial swelling was the most common presenting clinical feature at diagnosis (75.5%), followed by intraoral mucosal features other than ulceration such as cobblestoning and gingival enlargement (73.5%). Mucosal ulceration was observed in 36.7% of patients whereas extraoral facial manifestations such as cutaneous erythema and swelling were present in 40.8% of patients. Of the 45 patients who required treatment, 24 (53.3%) were treated with topical corticosteroids/immunosuppressants only, whereas 21 (46.7%) received a combined therapy (topical plus systemic corticosteroids/immunosuppressants and/or intralesional corticosteroids). The long-term outcome analysis showed complete/partial resolution of tissue swelling and oral ulceration in 78.8% and 70% of patients, respectively. LIMITATIONS: The main limitation of the current study was its retrospective design and methodology including differences in reporting clinical features and outcome. CONCLUSIONS: OFG can show multiple facial and mucosal clinical features. Long-term treatment with topical and/or combined therapy is needed in the majority of patients. Response to therapy is highly variable even though in the long-term complete/partial disease resolution can be obtained in the majority of patients. Mucosal ulceration tends to be more recalcitrant than orofacial swelling. Adverse side effects of therapy are rare.

Calcineurin inhibitors in oral medicine.

Topically applied calcineurin inhibitors have been suggested to be of some benefit in the treatment of immunologically mediated oral mucosal disorders, particularly oral lichen planus. This article reviews the current evidence of the efficacy and safety of topical calcineurin inhibitor agents in the management of different oral conditions. Current evidence suggests that topical tacrolimus and pimecrolimus may be of benefit (at least in the short term) in the treatment of immunologically mediated oral mucosal disease, especially oral lichen planus that has not responded to topical corticosteroids. Both tacrolimus and pimecrolimus are minimally absorbed through the oral mucosa and give rise to few clinically significant local or systemic adverse side effects. There is little evidence to indicate that topical cyclosporine is more effective than topical corticosteroids for the treatment of immunologically mediated oral mucosal disease. Currently, there is no objective evidence suggesting that topical tacrolimus or pimecrolimus increase the risk of oral malignancy associated with oral lichen planus. There is a need for well-designed randomized controlled trials to establish the precise efficacy of topical calcineurin inhibitors for the treatment of immunologically mediated oral mucosal disease.

Oral and Dental Health Status among Adolescents with Limited Access to Dental Care Services in Jeddah.

The purpose of this study was to assess the prevalence and associated factors of dental caries and periodontal diseases among 14⁻19-year-old schoolchildren with limited access to dental care services. A cross sectional study design was conducted during field visits to seven governmental schools in Al-Khomrah district, South Jeddah, over the period from September 2015 to May 2016. Clinical examinations and administered questionnaires were carried out in mobile dental clinics. The dentists carried out oral examinations using the dental caries index (DMFT), the simplified oral hygiene index (OHI-S), and the community periodontal index for treatment needs (CPITN). Statistical analyses were performed using SPSS 20. A total of 734 schoolchildren were examined. The prevalence of decayed teeth was 79.7% and was significantly higher among boys (88.9%) than girls (69.0%). About 11% of students had missing teeth, with a significantly higher figure among females than males (15.9% versus 7.3%); 19.8% of students had filled teeth. Moreover, a DMFT of seven or more was significantly more prevalent among males (43.3%) than females (26.8%), while the percentage of females with sound teeth was significantly higher than for males (20.4% and 9.6% respectively). The CPITN revealed 0, 1 and 2 scores among 14.6%, 78.2%, and 41.6% respectively. Males had a significantly higher percentage of healthy periodontal condition (23.8%) than females (3.8%). Dental caries prevalence was moderate to high, calculus and gingival bleeding were widespread among schoolchildren, and were more prevalent among students with low socioeconomic status.

Erythema multiforme and related disorders.

Erythema multiforme (EM) and related disorders comprise a group of mucocutaneous disorders characterized by variable degrees of mucosal and cutaneous blistering and ulceration that occasionally can give rise to systemic upset and possibly compromise life. The clinical classification of these disorders has often been variable, thus making definitive diagnosis sometimes difficult. Despite being often caused by, or at least associated with, infection or drug therapy, the pathogenic mechanisms of these disorders remain unclear, and as a consequence, there are no evidence-based, reliably effective therapies. The present article reviews aspects of EM and related disorders of relevance to oral medicine clinical practice and highlights the associated potential etiologic agents, pathogenic mechanisms and therapies.
