Behandeling van patiënten met ernstige kokhalsproblematiek :Een evaluerend onderzoek binnen het Centrum Bijzondere Tandheelkunde in het UMCG

(2017) Vries, J.J. de

Background: Gagging is a natural, protective reflex that occurs when a foreign object threats to come into the oropharynx. The gag reflex can be induced by different types of stimuli and the intensity differs for each individual. A disfunctional, extreme gag reflex can cause problems during the dental treatment or the wearing of a conventional denture. In the literature there is no agreement about the aetiology and prevalence from such a reflex. There is a lack of useful, valid measurement instruments and no consensus about the treatment method of preference.
Objective: The objective is to survey the patient population, treatment results and satisfaction among patients with gagging problemacy in a center for special dental care (CBT) in a hospital (UMCG) in Groningen, the Netherlands. Based on this, recommendations can be done to improve the treatment of patients with gagging problemacy.
Methods: It is an observational study that has been performed retrospectative. The patient list from the CBT in the UMCG was used. In the first part of the study, the patient dossiers from all patients that visited the CBT because of gagging problems from the 1st of January 2010 to the 1st of May 2016 were observed. This was followed by a structured interview with the patients who actually had been treated, provided that a VLEK (question list extreme gagging problemacy) was carried out during the intake. The structured interview contained several questions, including questions about the treatment effect on short-term and long-term, the satisfaction about treatment and positive/ negative elements of it.
Results: 116 patient dossiers were observed, of which 51 patients were selected for a structured interview. In 39 cases, a structured interview was actually performed. The majority of the referred patients consisted of male in the age of 40-60. More than half of the patients was referred by a general dental practioner. The self-reported short-term treatment effect was 4,95 on a scale from 0 (no effect) to 10 (gagging completely disappeared). The long-term effect differed not significantly (T = 94,50,
p= .180). The practioners recorded more often a positive effect for edentulous patients than for dentate patients, while not significant (U = 121, z= -2,027, p= .063). The mean rating for satisfaction about treatment was 7,95 on scale 0-10. Edentulous patiens were significant more satisfied than dentate patients (U = 97, z = -2,633,
p= .010).
Conclusions: Edentulous patiens are more satisfied about treatment for gagging problemacy at the center for special dental care in the UMCG than dentate patients.. This could be explained by the fact that the practioners recorded more often a positive effect for this group. Recommendations are improvement of the information provision (concerning treatment and treatment costs) and the administration with respect to appointments.
