Purpose: The purpose of this study was to examine the effects of oral cryotherapy on oral mucositis, reactive oxygen series, inflammatory cytokines, and oral comfort in patients undergoing chemotherapy for gynecologic cancers. Methods: Participants were randomly assigned to the experimental group (n=25, receiving oral cryotherapy during chemotherapy) and the control group (n=25, receiving the usual care consisting of 0.9% normal saline gargles three times before meals). Oral mucositis was assessed using the oral assessment guide, while oral comfort was assessed using the oral perception guide. Reactive oxygen series was measured as total oxidant stress, and the level of two inflammatory markers, interleukin-6 (IL-6) and tumor necrosis factor-alpha ($TNF-{\alpha}$), were examined. The data were analyzed using t-test, chi-square test, Fisher's exact test, Mann-Whitney U-test, and repeated measures analysis of variance. Results: There was a significant difference in the oral mucositis score, reactive oxygen series score, $TNF-{\alpha}$ level, and oral comfort score between the two groups, and there were significant changes over time and in the group-by-time interactions. There was a significant difference in the IL-6 score between the two groups, but there were no significant changes over time or in the group-by-time interactions. Conclusion: The study results revealed that oral cryotherapy was more effective than the usual care regime of normal saline gargles for reducing oral mucositis, reactive oxygen series, and inflammatory cytokines and for improving oral comfort in gynecologic cancer patients undergoing chemotherapy.

Purpose: This study examined the prevalence and risk factors of peri-implant disease after at least 7 years of dental implant loading. Methods: A total of 111 patients with 218 dental implants were treated. The follow-up period for all implants was at least 7 years. The patients' dental records were collected and risk factors of peri-implant disease were investigated through logistic regression analysis. Results: The overall implant survival rate was 95.87%, because 9 of the 218 implants failed. The prevalence of peri-implant mucositis and peri-implantitis was 39.7% and 16.7%, respectively. As risk factors, smoking and prosthetic splinting showed significant associations with peri-implantitis (P<0.05). Conclusions: Within the limits of this study, no significant correlations were found between any risk factors and peri-implant mucositis, but a significantly elevated risk of peri-implantitis was observed in patients who smoked or had splinted prostheses in 2 or more implants.

Background: Oral mucositis is a common complication of anticancer chemotherapy. The sequelae of this consist of an increased risk of infection, moderate to severe pain, compromised oral function, and bleeding. This study was performed to evaluated the effects of the He-Ne laser and the Ga-Al-As laser on oral mucositis caused by anticancer chemotherapy in pediatric patients. Methods: There were 3 cases of osteosarcoma and 6 cases of leukemia. All patients received He-Ne laser (632.8 nm wavelength, power 60 mW) application on 400-600 Hz scanning for 5-20 minutes and Ga-Al-As laser (904 nm wavelength, power 40 mW) application by fiberoptic hand piece placed in immediate proximity to the tissue without direct contact with it for 30 seconds per point for 5 days per week. During the application patients wore wavelength-specific dark glasses and were instructed to keep their eyes closed. Results: The mean number of treatments with oral intake was $4.89{\pm}0.64$. The mean number of total treatments was $9.44{\pm}2.59$. There were no significant side effects during and after the laser treatments. Conclusions: He-Ne laser and Ga-Al-As (IR) laser treatment were well tolerated and reduced the severity and duration of chemotherapy-induced oral mucositis in pediatric oncologic patients.

The present study aimed to determine the effect of oral ${\beta}$-glucan on mucositis and leukopenia in 62 consecutive patients with colorectal cancer treated with an adjuvant FOLFOX-4 regimen. The patients were retrospectively evaluated in 2 groups: one group received ${\beta}$-glucan and the other did not (control group). Leucocytes, neutrophils, and platelets were evaluated before and 1 week after chemotherapy and oral mucositis and diarrhea were noted. Leucocyte and neutrophil counts after chemotherapy in the ${\beta}$-glucan group were $7,300/mm^3$ and $3,800/mm^3$, respectively, and the reductions, as compared to baseline, were not significant (p=0.673 and 0.784). The median platelet count was $264,000/mm^3$ after chemotherapy in the ${\beta}$-glucan group and the reduction, as compared to baseline, was borderline significant (p=0.048). In the control group, reduction in leucocyte, neutrophil, and platelet counts was statistically significant. Oral mucositis and diarrhea were less common in the ${\beta}$-glucan group. We conclude that ${\beta}$-glucan can be used to reduce the adverse effects of chemotherapy.

Background and Aim: Although the functional consequences of MDR-1 polymorphisms have been the subject of numerous studies, to the best to our knowledge, associations with clinical side effects of anticancer drugs have yet to be assessed. Our aim was to clarify any role of the C3435T polymorphism of the MDR1 gene in oral mucositis and its relation with elevated reactive oxygen species (ROS) levels, in children with acute lymphoblastic leukemia (ALL). Materials and Methods: The distribution of the MDR-1 C3435T polymorphism in 47 patients with ALL was determined by RFLP and compared with that of 68 healthy controls. Results: There were no association in distribution of genotypes of MDR-1 C3435T polymorphism and the risk of ALL. Oral mucositis were detected in 78.7% (n=37) of the patients and significantly related to the MDR-1 CT genotype (p=0.042), as confirmed by logistic regression analysis. Conclusion: Our preliminary data suggest that children carrying the CT genotype are more prone to develop oral mucositis, which might mean that the heterozygous genotype leads to accumulation of more reactive oxygen species. Since a limited number of patients was investigated, further studies are needed to confirm these findings.

Background: Propolis based preparations have a wide range of applications in various specialties of dentistry. The aim of this clinical trial was to test the efficacy of propolis as a mouthwash in the reduction of chemotherapy induced oral mucositis (OM) in a single center. Materials and Methods: In this randomised, controlled study patients undergoing chemotherapy were included consecutively and randomised to an experimental group receiving propolis mouthwash (n = 20) and a control group receiving diluted water (n=20). Oral mucositis, erythema and eating and drink ability were assessed at baseline and after 3 and 7 days using the World Health Organization (WHO) scale and the oral mucositis assessment scale (OMAS). Results: There were significant differences in OM, wound and erythema in propolis group compared to placebo, but no significant difference in eating and drink ability. However, it was interesting that 65% of the patients in the propolis group were completely healed at day 7 of the trial. No significant adverse events were reported by the patients. Conclusions: This study found that oral care with propolis as mouthwash for patients undergoing chemotherapy is an effective intervention to improve oral health. Our findings shouldlencourage health practitioners to apply propolis mouth rinse for the oral care of patients under chemotherapy.

Purpose: The significance of keratinized tissue for peri-implant health has been emphasized. However, there is an absence of clinical evidence for the use of a xenogeneic collagen matrix (XCM) to manage peri-implant mucositis and peri-implantitis. Therefore, the purpose of this study was to investigate outcomes after keratinized tissue augmentation using an XCM for the management of peri-implant diseases. Methods: Twelve implants (5 with peri-implant mucositis and 7 with peri-implantitis) in 10 patients were included in this study. Non-surgical treatments were first performed, but inflammation persisted in all implant sites. The implant sites all showed a lack of keratinized mucosa (KM) and vestibular depth (VD). Apically positioned flaps with XCM application were performed. Bone augmentation was simultaneously performed on peri-implantitis sites with an intrabony defect (>3 mm). The following clinical parameters were measured: the probing pocket depth (PPD), modified sulcular bleeding index (mSBI), suppuration (SUP), keratinized mucosal height (KMH), and VD. Results: There were no adverse healing events during the follow-up visits (18±4.6 months). The final KMHs and VDs were 4.34±0.86 mm and 8.0±4.05 mm, respectively, for the sites with peri-implant mucositis and 3.29±0.86 mm and 6.5±1.91 mm, respectively, for the sites with peri-implantitis. Additionally, the PPD and mSBI significantly decreased, and none of the implants presented with SUP. Conclusions: Keratinized tissue augmentation using an XCM for sites with peri-implant mucositis and peri-implantitis was effective for increasing the KMH and VD and decreasing peri-implant inflammation.

Peri-implant diseases are inflammatory lesions, which include peri-implant mucositis and peri-implantitis. Peri-implant mucositis is described as the presence of inflammation in the mucosa around implants without any bone loss. By contrast, in peri-implantitis, besides the inflammation in the peri-implant mucosa, loss of supporting bone is also seen. Diagnosis of peri-implant diseases require the use of gentle probing(0.2 ~ 0.3N) to identify the presence of bleeding on probing, probing depth and suppuration, both signs of clinical inflammation. Radiographs are required to detect loss of supporting bone. Baseline probing measurements and high quality, long cone periapical radiographs should be obtained once the restoration of the implant is completed to make possible longitudinal monitoring of peri-implant tissue.

Purpose: This study was conducted to develop and evaluate an oral care protocol for cancer patients receiving chemotherapy. Methods: The participants in this study were cancer patients in Severance hospital in Seoul. A total of 31 patients were assigned to the experimental group, and 29 patients to the control group. Data were collected from August 1 to October 5, 2010. The protocol included definition and symptom of oral mucositis, self-check method of oral status, prophylactic method of oral mucositis (oral care, eating habits, and gargling) and management of oral mucositis. Oral Assessment Guide (OAG) was used as the measurement tool of oral mucositis in this study, Oral Care Performance Scale was used as the measurement tool of oral care performance status. Data were analyzed with a $x^2-test$ and t-test, and repeated measures ANOVA, using SPSS/WIN 18.0 program. Results: Patients in the experimental group receiving the oral care protocol had a significant difference (t=-2.938, p=.005) in the oral care performance compared to the control group. However, there was no significant difference (F=1.255, p=.274) in the oral mucositis status between two groups. Conclusion: This study showed that the oral care protocol could improve oral care performance status for the patients under chemotherapy.
