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 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.
