Streszczenie

Wprowadzenie. W dostępnej literaturze nie odnaleziono badań określających, czy diagnoza bruksizmu w czasie snu (ang. sleep bruxism, SB) jest możliwa za pomocą folii BruxChecker®.
Cel pracy. Weryfikacja hipotezy badawczej, że u pacjentów z „prawdopodobnym” bruksizmem w czasie snu nasilenie zgrzytania rejestrowane na folii BruxChecker® jest większe niż w grupie kontrolnej.
Materiał i metody. Do udziału w badaniu zakwalifikowano 48 pacjentów (34 kobiety i 14 mężczyzn), których podzielono na dwie grupy – osoby z prawdopodobnym bruksizmem w czasie snu i pozostałych. Diagnoza prawdopodobnego bruksizmu w czasie snu opierała się na ankiecie badawczej, wywiadzie i badaniu klinicznym. Wszyscy pacjenci otrzymali 3 folie BruxChecker®. Pierwsze dwie użyto do eksperymentalnego zaciskania i zgrzytania zębami. Ostatnią pacjenci użytkowali w czasie snu przez jedną noc. Wykonano zdjęcia wszystkich folii BruxChecker® aparatem umieszczonym na statywie w celu porównania widocznych pól starcia barwnika. Ustalono wartości mniejszych i większych odpowiedników zgrzytania (OM i OW) po obu stronach łuku zębowego. Wyznaczono krzywe ROC obrazujące szanse wystąpienia SB w zależności od wartości OM i OW. Do analizy statystycznej użyto regresji logistycznej.
Wyniki. W grupie osób z prawdopodobnym bruksizmem w czasie snu mediana OM była większa niż w grupie kontrolnej: 300 (20–300) vs 50 (5–100), p = 0.033. Iloraz szans dla tej zależności wynosił 1,37 na 50 czynności zgrzytania (95% CI: 1,07–1,75; p < 0,014), a pole pod krzywą ROC wynosiło 0,69, 95% CI: 0,53–0,84. Czułość i swoistość dla punktu odcięcia na poziomie 300 zgrzytnięć wynosiła odpowiednio 53 i 83%.
Wnioski. Na podstawie analizy folii BruxChecker® potwierdzono hipotezę, że nasilenie zgrzytania u osób ze stwierdzonym bruksizmem „prawdopodobnym” jest większe niż w grupie kontrolnej.

Abstract

Background. There are no studies to determine if it is possible to diagnose sleep bruxism (SB) with the BruxChecker®.
Objectives. The aim of the study was to verify the hypothesis that grinding registered with the BruxChecker foils is more intense in “probable” sleep bruxers than in controls.
Material and Methods. Forty-eight patients (34 women and 14 men) were selected for the study. They were divided into two groups – probable sleep bruxers and the rest. Probable sleep bruxism diagnosis was based on a questionnaire, interview and clinical examination. All patients received 3 BruxChecker® foils. First two foils were used for experimental clenching and grinding and the last to wear during one night. Photographs of all BruxChecker® foils with a camera on a tripod were taken to compare visible ground areas. Smaller and bigger grinding equivalents (ES and EB) were estimated for two sides of the dental arch. ROC curves were generated for prediction of SB depending on ES and EB values. Logistic regression was used in statistical analysis.
Results. In probable sleep bruxers, median of ES was higher compared to control group, 300 (20–300) vs. 50 (5–100), p = 0.033. The odds ratio for the relation was 1.37 per 50 grindings (95% CI: 1.07–1.75; p < 0.014) and area under the ROC curve was 0.69, 95% CI: 0.53–0.84. Sensitivity and specificity for cut-off point of 300 grindings were 53% and 83%, respectively.
Conclusion. Based on BruxChecker analysis it was confirmed that grinding registered with the BruxChecker foils is more intense in “probable” sleep bruxers than in controls.
