Associations of oral health items of the Vanderbilt Head and Neck Symptom Survey with a dental health assessment

SummaryObjectivesThe Vanderbilt Head and Neck Symptom Survey (VHNSS) version 2.0 oral symptom subscale addresses underreported oral health issues. We report the associations of xerostomia, dental health, dentures and trismus questions with oral examination findings.Materials and methodsBetween May 2011 and April 2012, fifty head and neck cancer (HNC) patients treated with chemoradiotherapy completed the 50-item VHNSS survey, an oral health assessment by a dentist, salivary flow, and inter-incisal opening (IIO) measurements.ResultsPatient reported “problems with dry mouth” correlated with unstimulated salivary flow (−0.43, p = 0.002). “Cracked teeth” (0.55, p = <0.001) or “difficulty chewing due to teeth” (0.43, p = 0.004) correlated with urgent/emergent dental issues identified on clinical exam. Scores of >4 on any dental question identified 83% of patients with urgent or emergent needs. The ROC curve separated routine from urgent/emergent dental issues (0.89, p < 0.001). IIO correlated with reported jaw movement “limitations” (−0.43, p = 0.002). Small numbers of patients with dentures precluded meaningful analysis of this subsample.ConclusionsClinically significant oral health issues pertaining to xerostomia, dental health and trismus may be identified using the oral health subscale of the VHNSS version 2.0. MASCC guidelines should be followed by patients with xerostomia. The observation that a score of >4 is highly predictive of dental issues is important and needs further validation. If confirmed, this would be a useful screening tool for identifying and referring HNC patients for dental care. Patients with trismus should receive physical therapy.
