OBJECTIVES: Necrotizing ulcerative gingivitis (NUG) has been seen in military populations throughout history. This study aims to determine the prevalence, treatment modality and risk factors associated with NUG in the British Armed Forces. MATERIALS AND METHODS: A whole population dataset of the British Armed Forces was searched to determine cases of NUG during the period 1 January to 31 December 2012. Individual case records were identified, and a case-control study undertaken with data gathered and analysed against a randomised control group, matched for age, sex and service. RESULTS: A prevalence rate for NUG of 0.11 % was determined against the whole military population. The majority of cases received (alone or in combination) the following: oral hygiene instruction (66.5 %), antibiotics (64.4 %) and a mouthwash (58.1 %). Of the cases, 48.7 % received debridement. Analgesics were only prescribed in 8.4 % of the cases, and smoking cessation advice was only given in 10.7 % of the cases. Analysis of risk factors against the control group showed an increase in odds ratios for diagnosis of NUG of 3.4 (95 % CI 2.0-5.7) for current smokers and 7.3 (95 % CI 1.9-28.0) for individuals with an overall Basic Periodontal Examination (BPE) score of 3. CONCLUSIONS: Whilst NUG is a rare disease, it is evident from this study that it still occurs within the British Armed Forces. A strong association was shown between NUG and current smokers and those cases with an overall BPE score of 3. CLINICAL RELEVANCE: This study provides prevalence data for NUG in the British Armed Forces and description of its treatment and associated risk factors. Oral hygiene and smoking must be addressed in patients with NUG and prescribing protocols should be carefully followed.
