Oral Health-Related Knowledge, Attitude and Practice among Patients in Rural Areas around Cluj-Napoca, Romania.

The intent of the KAP (knowledge, attitude, practices) survey is to collect information about a specific target group related to their knowledge, what they consider to be known, and what they do about a particular topic. The aim of this study was to identify the level of importance of oral health, especially the level of knowledge, attitude and practices of rural patients around Cluj-Napoca, Romania. MATERIAL AND METHODS: A questionnaire consisting of five parts was used, trying to assess the self-perception of oral health, knowledge and attitude towards oral health, dental hygiene practices and eating habits. A clinical examination was also performed in order to identify the number of missing teeth, the caries and the presence of calculus. RESULTS: The study revealed that most patients have an average and good self-perception of oral health, although three-quarters of them have calculus deposits, and about half of them have more than three carious lesions and at least one extracted tooth. There is also a discrepancy between declared knowledge of oral health, eating habits and dental practices. CONCLUSIONS: The basic knowledge of rural patients about oral health can be considered satisfactory, but the practices, unfortunately, do not reflect this knowledge.

The Influence of Hepatitis C Virus Infection on ORAL Health-Related Quality of Life in Patients with Oral Lichen Planus.

BACKGROUND: oral lichen planus (OLP) is a mucocutaneous disease that affects about 4% of the global population. Hepatitis C virus (HCV) was linked to lichen planus. The current study aimed to assess the impact of OLP associated or not with HCV infection on the oral health-related quality of life (OHRQoL). METHODS: The study included patients diagnosed with OLP who filled in the Romanian version of OHIP-14 questionnaire at their first appointment and 6 months later, after the OLP treatment. A control group of OLP-free subjects similar as age and sex was also included in the study. Results: 68 patients with OLP and 46 controls were included in the study. The OHIP scores are significantly higher on OLP group than controls (p-value < 0.0001) and significantly reduced at 6-month follow-up (p-values: < 0.0001 pre- vs. post-treatment in OLP group). Patients with and without HCV associated with OLP demonstrated a similar oral quality of life (p-values > 0.05). Conclusions: the OHRQoL for patients suffering from OLP is compromised but is improved after treatment. The HCV associated with OLP did not influence the overall OHRQoL, but the patients who associate HCV reported more frequently aching in the mouth and discomfort eating food at six-month follow-up.

Diagnostic Criteria of Oral Lichen Planus: A Narrative Review.

Oral lichen planus (OLP) is a disease with unclear etiology or pathogenesis, categorized by the World Health Organization as oral lichenoid lesions (OLL; interface mucositis or lichenoid mucositis) into a group of potentially malignant disorders. The diagnosis of OLP is challenging because the clinical and histopathologic features are frequently seen in OLP, OLL and/or other mucosal diseases with lichenoid characteristics. Furthermore, OLP has a dynamic nature. Finally, an early and precise diagnosis can play a decisive role, allowing timely treatment and thus improving the patient quality of life. This article summarizes the state-of-the-art regarding OLP and OLL and discusses the challenges faced on making an accurate diagnosis, aiming to provide a practical guideline for the postgraduates and oral physicians in reaching the diagnosis of these lesions.

Osseointegration of zirconium dental implants three months after insertion in rabbit femur. Histopathological study.

Implantology is a highly researched field with a constant concern in finding and studying new implant materials. Lately, zirconium has become a very attractive alternative to the detriment of titanium, but the research results were sometimes contradictory. Thus, we considered as opportune to study the osseointegration of zirconium dental implants in rabbit femur, three months after insertion. The biological material was represented by five rabbits and the experimental protocol was approved by the Ethics Committee of the University of Oradea, Romania. The implants (zirconium ceramic dental implants: 5 mm length, 2.6 mm diameter) were inserted in the femur under controlled conditions, after creating a bone defect. The animals received the appropriate postoperative care. Three months later, the implantation area was harvested and processed for histological examination. The assessment of the osseointegration process of the zirconium implants showed that they were very well tolerated by the host organism that did not trigger any rejection processes. Approximately 80% of the compromised bone was replaced with newly formed bone in advanced stages of remodeling and consolidation. The proliferated bone near the implants acquired a structure similar to the rabbit diaphyseal bone, but with higher density and size of the osteons. The stage reached by the osseointegration process three months after the insertion of the implants, ensures a good consolidation of the implants that supports the prosthetic structures, which are to be built on them.
