Knowledge, attitudes, and practice related to tooth loss and dentures among patients with dental arch deficiencies.

BACKGROUND: Tooth loss is a common problem that affects many people worldwide. Exploring knowledge, attitude, and practice (KAP) among patients can identify barriers and challenges in following recommended practices, providing valuable insights for dental healthcare providers, policymakers, and researchers. This study aimed to explore the KAP of patients with dental arch deficiencies regarding tooth loss and dentures. METHODS: This web-based, cross-sectional study was conducted among patients with dental arch deficiencies using a self-designed questionnaire. RESULT: 3166 valid questionnaires were included. Participants' mean KAP scores were 6.84 ± 2.27 (possible range: 0 ~ 12), 39.4 ± 3.72 (possible range: 9 ~ 45), and 27.7 ± 4.36 (possible range: 8 ~ 40), respectively. Multivariable logistic regression analysis showed that knowledge (OR = 1.383), employed (OR = 1.805), family history (OR = 2.158), and treatment (OR = 1.683) were independently associated with attitude. Moreover, knowledge (OR = 1.239), attitude (OR = 1.250), female (OR = 0.619), age (OR = 0.967), college/bachelor (OR = 0.373), and master and above degree (OR = 0.418), employed (OR = 0.554) or student (OR = 0.434), with 10,001-20,000 Yuan household income per month (OR = 0.492), have been married (OR = 0.609), smoking (OR = 0.595), drinking (OR = 0.397), disease duration (OR = 0.972), with family history (OR = 1.676), and with treatment (OR = 3.492) were independently associated with practice (all P < 0.05). CONCLUSION: Patients with dental arch deficiencies have insufficient knowledge, positive attitudes, and moderate practice toward tooth loss and dentures, which might be affected by multiple demographic factors.

Knowledge, attitude, and practice of dental patients toward dental defects and dental fillings in Jinan, Shandong Province, China: a mediation analysis.

BACKGROUND: Dental filling is a prevalent method for treating dental defects. This study aimed to investigate the knowledge, attitude, and practice (KAP) toward dental defects and dental fillings among dental patients in Jinan, Shandong Province, China. METHODS: This cross-sectional study was conducted at the main campus and several branch campuses of Jinan Stomatological Hospital, and community locations within Jinan city between October 2023, and January 2024. Spearman correlation analysis and mediation analysis were used to assess the associations and interrelationships between KAP scores. RESULTS: In this study, 2529 dental patients participated, with 69.1% being females. Of these, 1711 had no dental defects, 551 had defects and fillings, and 267 had defects without fillings. Their median knowledge, attitude, and practice (Questions 1-6) scores were 8.00 [5.00, 12.00] (possible range: 0-18), 27.00 [26.00, 29.00] (possible range: 10-50), and 19.00 [15.00, 24.00] (possible range: 9-45), respectively. Mediation analysis revealed that in patients without dental defects, knowledge had a direct effect on attitude (ß = -0.983, 95% CI: -0.999, -0.966, P < 0.001). Additionally, attitude had a direct effect on practice (ß = -0.797, 95% CI: -1.490, -0.103, P = 0.024), while knowledge had an indirect effect on practice through attitude (ß = 0.783, 95% CI: 0.096, 1.470, P = 0.026). In patients with dental defects who had undergone dental fillings, significant direct effects were observed between knowledge and attitude (ß = -0.736, 95% CI: -0.821, -0.650, P < 0.001), knowledge and practice (ß = 0.396, 95% CI: 0.214, 0.577, P < 0.001), and attitude and practice (ß = -0.499, 95% CI: -0.683, -0.315, P < 0.001). Moreover, knowledge had an indirect effect on practice (ß = 0.367, 95 CI: 0.221, 0.513, P < 0.001). In patients with dental defects but without any fillings, direct effects were found between knowledge and attitude (ß = -0.929, 95% CI: -1.028, -0.829, P < 0.001). CONCLUSIONS: Dental patients had inadequate knowledge, attitude, and practices concerning dental defects and fillings. It is recommended that clinical interventions should focus on enhancing patient education and promoting positive engagement in dental care practices.

Knowledge, attitude, and practice toward self-control of dental plaque among patients with periodontal diseases: a cross-sectional study.

BACKGROUND: The development of periodontal disease is closely linked to individual oral healthcare behaviors. This study aimed to investigate the knowledge, attitude, and practice (KAP) toward the self-control of dental plaque among patients with periodontal diseases. METHODS: This cross-sectional study was conducted at Jinan Stomatological Hospital between July 2022 and September 2022 through a self-administrated questionnaire for patients with periodontal diseases. RESULTS: A total of 563 participants were included. Among them, 147 (26.11%) had gingivitis and 416 (73.89%) had periodontitis. Participants' knowledge, attitude, and practice scores were 8.71 ± 2.81 (range 0-12), 39.82 ± 3.69 (range 10-50), 33.13 ± 5.91 (range 11-55), respectively. The multivariate logistic regression analysis showed that the knowledge [odds ratio (OR) = 1.212, 95% confidence interval (CI): 1.097-1.339, P < 0.001], attitude (OR = 1.132, 95% CI: 1.070-1.198, P < 0.001), occupation, especially in the commercial and service industry (OR = 0.488, 95% CI: 0.221-1.080, P = 0.007), and income of 10,000-20,000 yuan (OR = 0.476, 95% CI: 0.258-0.877, P = 0.017) were independently associated with good practice. CONCLUSIONS: Chinese patients with periodontal diseases demonstrated satisfactory knowledge and attitudes regarding oral hygiene, but the practical aspects need more promotion and training, especially in daily brushing frequency, usage of oral irrigator and interdental brush. Individualized approach should consider patients' knowledge, attitudes, occupation and income level.

To Explore and Analyze the Safety and Clinical Efficacy of Periocline-Assisted Periodontal Basic Therapy on Chronic Periodontitis.

Objective: This study aimed to investigate and analyse the clinical efficacy and safety of periocline-assisted periodontal foundation in the therapy of chronic periodontitis. Methods: From May 2018 to January 2021, 108 patients with chronic periodontitis were treated at our institution and randomly assigned equally to either the control or the experimental group. The plaque index (PLI), sulcus bleeding index (SBI), probing depth (PD), and periodontal attachment level (AI) were evaluated before and after periodontal basic therapy in the control group and periocline as an adjunct in the experimental group. Lactobacillus (LB) and Porphyromonas gingivalis (PG) concentrations in saliva were measured before and after therapy, and adverse responses during treatment were noted. Results: The levels of PLI, SBI, PD, and AI in the two groups were significantly lower in both groups at 1 and 3 months posttreatment compared to baseline; the levels of PLI and SBI were higher, and the levels of PD and AI were lower at 3 months after treatment compared to 1 month after treatment; compared with the control group at 1 month and 3 months after treatment, the levels of PLI, SBI, PD, and AI in the experimental group were lower than those in the control group (P < 0.05). The LB level was higher and the PG level was lower in both groups compared to baseline at 1 and 3 months posttreatment. The LB level was higher and the PG level was lower at 3 months posttreatment compared to 1 month after treatment. Compared with the control group at 1 month and 3 months after treatment, the LB level was higher, and the PG level was lower in the experimental group (P < 0.05). No significant adverse effects were observed in either group during the treatment period. Only 1 patient in the experimental group had mild gastrointestinal reactions, mainly nausea, without obvious neurological symptoms or abnormal blood changes, which did not affect the treatment. Conclusion: Periodontal fundamental therapy with perioclines may be a potential treatment for persistent periodontitis. It improves the primary clinical indicators, increases dysbacteriosis control, and has a strong safety profile. It could effectively control the development of clinical symptoms of periodontitis and reduce tissue destruction, with obvious clinical treatment effects. It could be used as the first choice for topical treatment of chronic periodontitis. It is recommended for further study by a wide range of researchers.

LncRNA LUADT1 Promotes Oral Squamous Cell Carcinoma Cell Proliferation by Regulating miR-34a/GAS1 Axis.

INTRODUCTION: The oncogenic role of lncRNA LUADT1 has been investigated only in lung cancer. This study aimed to investigate the role of LUADT1 in oral squamous cell carcinoma (OSCC). PATIENTS AND METHODS: The expression levels of LUADT1 in paired OSCC and non-tumor tissues from OSCC patients were determined by RT-qPCR. A 5-year follow-up study was performed to analyze the prognostic value of LUADT1 for OSCC. Dual-luciferase assay and overexpression experiments were performed to assess the interactions among LUADT1, miR-34a and GASL1. Cell proliferation was analyzed by cell proliferation assay. RESULTS: In this study, we found that LUADT1 was upregulated in OSCC and predicted poor survival. LUADT1 was predicted to interact with miR-34a, which was confirmed by dual-luciferase activity assay. However, overexpression experiments showed that they did not affect the expression of each other. Interestingly, overexpression of LUADT1 resulted in upregulation of GAS1, a target of miR-34a. Cell proliferation assay revealed that overexpression of LUADT1 and GAS1 resulted in promoted cell proliferation. MiR-34a played an opposite role and reversed the effects of LUADT1 overexpression. CONCLUSION: LUADT1 may promote OSCC proliferation by regulating miR-34a/GAS1 axis.
