Exploring the correlation between periodontal disease and serum biomarkers in haemodialysis patients.

BACKGROUND: Patients undergoing haemodialysis are more susceptible to infectious diseases, including periodontitis. This study aimed to investigate the Correlation between periodontal disease and serum markers in Yemeni haemodialysis patients. METHODS: A cross-sectional study was conducted on a sample of 70 haemodialysis patients. Patient interviews, clinical examinations, and laboratory tests were performed to collect data. Serum levels of albumin, calcium, phosphorus, haemoglobin, ferritin, and creatinine were measured, with separate measurements for cystatin C The association between categorical variables was assessed using the chi-square test and Pearson's correlation coefficient, considering a significance level of p < 0.05. RESULTS: Significant correlations were found between serum biomarkers and periodontal clinical parameters. Phosphorus, creatinine, albumin, ferritin, and creatinine levels correlated significantly with the Plaque Index (p < 0.001, p < 0.001, p = 0.015, p = 0.018, and p = 0.03). While the Ferritin level showed significant correlations with both the Plaque Index and Miller Classes (r = 0.281, p = 0.018 and r = 0.258, p = 0.031), respectively. The Calcium level showed a significant correlation with the Gingival Index (r = 0.266, p = 0.027). Cystatin C level was statistically correlated with mobility (r = 0.258, p = 0.031). Also, the result showed a significant correlation between Creatinine levels and Periodontitis (r = 0.26, p = 0.03). CONCLUSION: This study provides evidence of a strong association between periodontal disease and chronic kidney disease in Yemeni haemodialysis patients. The findings emphasize the significance of maintaining good oral health in the care of haemodialysis patients.

A comparative study of the effects of advanced platelet-rich fibrin and resorbable collagen membrane in the treatment of gingival recession: a split-mouth, randomized clinical trial.

AIM: This study aimed to assess the effectiveness of advanced platelet-rich fibrin (A-PRF) combined with the pinhole surgical technique (PST) for enhancing root coverage (RC) in individuals with Miller class I or II gingival recessions (GR). Additionally, it compared the clinical effect of A-PRF and resorbable collagen membrane (RCM). MATERIALS AND METHODS: A total of 18 patients, encompassing 36 treatment sides of 18 Miller class I or II, were randomly assigned to the PST + A-PRF side (18 sides) and the PST + RCM side (18 sides). Clinical assessments of various parameters, including plaque index (PI), clinical attachment level (CAL), keratinized tissue width (KTW), recession depth (RD), recession width (RW), and gingival thickness (GT) were conducted at baseline and three months after the surgical procedure. A numeric rating scale (NRS) was also evaluated during the 1st, 2nd, 3rd and 4th days. This study was formally recorded under the TCTR identification number TCTR20230613005 in the Thai Clinical Trials Register-Medical Research Foundation of Thailand (MRF) on 13/06/2023. Furthermore, it was ethically approved by Sana'a University's Ethical Committee for Medical Research. RESULTS: When comparing the values of 3 months follow-up with the baseline values, intra-side comparison of the PST + A-PRF group showed significant improvements in PI (P = 0.02), CAL (P = 0.01), and RD (P = 0.04), and GT values (P < 0.01). The improvements in the PST + A-PRF group were through the reduction of baseline values of PI, CAL, and RD; the mean reductions in PI, CAL, and RD were 0.44 ± 0.71, 0.33 ± 0.45, and 0.22 ± 0.43 respectively, and a significant increase in GT value (0.44 ± 0.24). While there was an insignificant increase in KTW value with no change in RW values (4.50 ± 0.71, P = 1). In contrast, intra- side comparison of PST + RCM side showed only a significant reduction in PI value (0.44 ± 0.71, P = 0.02) and a significant increase in GT value (0.42 ± 0.26, P = < 0.01). Meanwhile, there were insignificant improvements in CAL (2.89 ± 0.95), KTW (3.97 ± 0.74), and RD (1.94 ± 0.87) values. Regarding inter-side comparison, there were no statistically significant among all variables (p > 0.05). The pain scores of the numeric rating scale were significantly lower on the PST + A-PRF sides compared with the PST + RCM sides, especially on the 1st, 2nd, and 3rd days (P < 0.001). CONCLUSION: Both A-PRF and RCM showed not wholly satisfactory outcomes in gingival recession treatment. Interestingly, the combination of PST with A-PRF has proven more effective than combining PST with RCM. Additionally, the localized application of A-PRF has been shown to reduce post-operative pain following the pinhole surgical technique.

Relationship between Undernutrition and Periodontal Diseases among a Sample of Yemeni Population: A Cross-Sectional Study.

Undernutrition is an inadequate supply of energy and nutrients. Periodontal diseases (PDs) are defined as a broad form of chronic inflammatory disease of the gingiva, bone, and ligaments supporting the teeth. This study aimed to reveal the relationship between undernutrition, using body mass index (BMI) and serum albumin level (Alb), and PDs in a sample of Yemeni population. A cross-sectional study was conducted at dental teaching clinics at the Faculty of Dentistry, Sana'a University. Of 1920 patients who attended clinics, only 229 matched the study criteria. Oral examination was performed to assess the periodontal clinical parameter measurements. BMI and Alb were measured. Participants of both genders were involved, with a slight increase in males (n = 134, 58.5%), and most of the study sample was in the age group of 18-35 years (n = 209, 91.3%). Regarding habits, only 18.2% (n = 43) of patients were smokers and about half of the participants (n = 136, 59.4%) were khat chewers. Most cases had mild undernutrition according to BMI (n = 139, 60.7%) and normal Alb level (n = 213, 93%). Regarding the periodontal diagnosis, most of the participants were diagnosed with gingivitis (n = 186, 81.2%). BMI and albumin level were nonsignificantly associated with PDs. PDs were statistically significant with the participant's age, gender, level of education, and smoking (P > 0.05). However, BMI, khat chewing, and albumin level were nonsignificant factors of periodontal diseases among Yemeni participants (P > 0.05). In both genders, variables such as age of the patients, smoking, khat chewing, and PDs were nonsignificantly associated with BMI. This study showed that the majority of the participants had been diagnosed with gingivitis, but there was not an association between PDs and undernutrition.

Risk factors for periodontal diseases among Yemeni type II diabetic patients: a case-control study

BACKGROUND: chronic periodontal diseases are one of diabetes mellitus complications. The present study aims to compare the periodontal status of type II diabetic patients to a control group and assess the role of risk factors in both groups. MATERIALS AND METHODS: A case-control study was conducted of 270 individuals (132 type II diabetics and 138 non-diabetics). Full mouth periodontal examination including plaque index, gingival bleeding, gingival recession, clinical attachment loss (CAL), tooth mobility, furcation involvement and the number of missing teeth. The case group was subdivided according to glycosylated hemoglobin (HbA1c) status (poorly controlled HbA1c >8 and well controlled HbA1c≤8) Likewise, the duration of diabetes mellitus as short or long duration (DM≤10 or >10). The diabetic group was also subdivided according to smoking and Khat chewing habits. RESULT: The severity of periodontal disease among type II diabetic patients were significantly higher compared to the control group regarding the plaque index 2.6 (1.6-4.3), bleeding on probing 3.5 (2.3-13.0), gingival recession 2.0 (1.2-3.4), furcation involvement 4.0 (2.3-6.7), clinical attachment loss 5.7 (3.1-10.5), tooth mobility 2.0 (1.2-3.4), and number of missing teeth 4.4 (2.3-8.5). In addition, poorly controlled type II DM and long duration had higher CAL and number of missing teeth than well-controlled DM and short duration. No significant differences were found between smokers/nonsmokers and Khat chewers/non-chewers among the diabetic group. CONCLUSION: Type II diabetic patients have severe periodontal destruction and tooth loss compared to non-diabetic people and there were no differences within the diabetic group in regards to smoking and Khat chewing habits.(

Tongue lesions and anomalies in a sample of Yemeni dental patients: a cross-sectional study

Background: Tongue examination helps considerably in diagnosing the underlying health state of the patient, especially in the cases of chronic diseases. The aim of this study is to determine the prevalence and association of tongue lesions with risk factors among Yemeni dental patients. Materials and methods: An oral medicine specialist examined all 713 patients attending the dental polyclinics at the University of Sciences and Technology (Sana’a, Yemen). The examination sheet was designed to include information related to patient characteristics, medical history, dental history, habits, and tongue lesions. Results: The prevalence of tongue lesions among the examined participants was 76.5 percent. The prevalence rate was 83.4 percent for males and 69.2 percent for females. Fissured tongue was the most common condition. Logistic regression analysis indicated that older age (p<0.001), gender (p=0.007), khat chewing (p<0.001), and smoking (p=0.001) were associated with fissured tongue; gender (p<0.001), khat chewing (p<0.001), and smoking (p<0.001) were associated with hairy tongue; and older age (p<0.001), khat chewing (p=0.001), and smoking (p=.021) were associated with coated tongue. Conclusion: The prevalence of tongue lesions among this sample of Yemeni population was 76.5 percent; fissured tongue and hairy tongue were the most prevalent lesions. Khat chewing, smoking, and older age were the associated risk factors for many of studied lesions and anomalies.
