The preventive effect of chewing gum containing maltitol, xylitol, gum base, and sugar on remineralization were investigated. The clinical study consisted of 8 weeks' randomized, double blind, controlled, cross-over clinical trials including 24 healthy adults had chew gum. After each test week, remineralization effect was evaluated by measuring microhardness and scanning electron microscopy (SEM). Microhardness of experimental chewing gum containing maltitol or xylitol was significantly higher than that of sugar gum (p<0.005). Images of SEM showed the remineralization effect of gum containing gum base, maltitol, or xylitol compared with sugar gum. Maltitol and xylitol gums were more effective in remineralization than sugar gum. It was concluded that maltitol and xylitol can be used as sugar substitute to prevent dental caries.

솔비톨의 형태와 입자크기가 무설탕 츄잉껌의 텍스쳐에 미치는 영향을 살펴보기 위하여 두 가지 형태인 치밀한 구조를 지닌 P-type과 듬성한 구조를 지닌 S-type의 솔비톨과 50 mesh와 100 mesh의 솔비톨을 사용하였다. 츄잉껌에 사용한 솔비톨 형태는 S-type이 P-type보다 더 유연하였고, 50 mesh의 솔비톨 보다 100 mesh가 더 유연하였다. 솔비톨의 강도는 S-type보다 P-type에서 컸으며 50 mesh보다 100 mesh에서 크게 나타났다. 이것은 덜 치밀한 구조를 지닌 솔비톨이 사용된 무설탕 츄잉껌이 높은 유연성과 낮은 강도를 보여 줌을 의미하고 입자의 크기가 작은 솔비톨을 사용할수록 무설탕 츄잉껌의 유연성과 강도가 증가됨을 의미한다. 그러므로 본 실험에서는 유연성이 높고 강도가 상대적으로 낮은 S-type의 솔비톨을 무설탕 츄잉껌의 원료로 선택하였다. 선택한 S-type 솔비톨이 함유된 무설탕 츄잉껌의 솔비톨의 입자크기에 따른 유연성과 강도를 측정한 결과 80 mesh 입자가 츄잉껌의 고체상 원료로 적합하였다. 80 mesh의 S-type 솔비톨이 함유된 무설탕 츄잉껌의 온도변화에 따른 유연성과 강도를 측정하였다. 실험 결과 온도가 증가할수록 무설탕 츄잉껌의 유연성은 증가하였으나 강도는 감소하였다.

Objective: To compare the effectiveness of ibuprofen, acetaminophen, and chewing gum for orthodontic pain relief and to assess if chewing gum can be a non-pharmacological alternative for orthodontic pain relief. Methods: The study enrolled 106 patients of both sexes, aged ≥ 12 years, with body weight > 50 kg, and mild-to-moderate dental crowding in the upper arch. After randomization and allocation concealment, the intervention groups were either administered with ibuprofen (400 mg) or acetaminophen (500 mg) or chewed sugar-free chewing gum immediately after initial archwire placement and every 6 hours for 1 week if the pain persisted. The control group did not receive any pain relief. The pain was assessed on a 100-mm visual analog scale at rest and while biting down at T1 (2 hours), T2 (24 hours), T3 (2 days), T4 (3 days), T5 (7 days), and T6 (21 days). Statistical analyses were performed using the Kruskal-Wallis and post-hoc Mann-Whitney U tests (α = 0.05). Results: The chewing gum group experienced more pain relief than the ibuprofen group at while biting down at T3 (p = 0.04) and at rest at T4 (p < 0.001). The chewing gum group reported more pain relief than the acetaminophen and control groups while biting down at T3 (p = 0.03 and p = 0.0006, respectively) and T4 (both p < 0.001). Conclusions: Chewing gum can be a non-pharmacological alternative for orthodontic pain relief at 2 and 3 days after initial archwire placement.

Objective: The purpose of this study was to evaluate the effects of chewing gum and low-level laser therapy in alleviating orthodontic pain induced by the initial archwire. Methods: Patients with 3-6 mm maxillary crowding who planned to receive non-extraction orthodontic treatment were recruited for the study. Sixty-three participants (33 females and 30 males) were randomly allocated into three groups: laser, chewing gum, and control. In the laser group, a gallium aluminum arsenide (GaAlAs) diode laser with a wavelength of 820 nm was used to apply a single dose immediately after orthodontic treatment began. In the chewing gum group, sugar-free gum was chewed three times for 20 minutes-immediately after starting treatment, and at the twenty-fourth and forty-eighth hours of treatment. Pain perception was measured using a visual analog scale at the second, sixth, and twenty-fourth hours, and on the second, third, and seventh days. Results: There were no statistically significant differences between the groups at any measured time point (p > 0.05). The highest pain scores were detected at the twenty-fourth hour of treatment in all groups. Conclusions: Within the limitations of the study, we could not detect whether low-level laser therapy and chewing gum had any clinically significant effect on orthodontic pain. Different results may be obtained with a higher number of participants or using lasers with different wavelengths and specifications. Although the study had a sufficient number of participants according to statistical analysis, higher number of participants could have provided more definitive outcomes.
