Knowledge and awareness of oral health issues are essential for prevention of dental and other associated systemic diseases. This study explores among visually impaired subjects living in Jazan region, with the respect to frequency and quality of use and the effect of type of blindness on the distribution of oral health related knowledge and behavior. Supervisors taking care of visually impaired subjects of different degrees were informed about the aim of the study. A total of 92 questionnaires were distributed randomly to be completed by the consent participants from each age group, gender and categories of blind situation. First, a consent letter was carefully read to the participants by the interviewer and data collected, and then processed and analyzed by means of the Statistical Package for Social Sciences. In total, 71.5% total blinds and 63.6% partial blinds scored high in the knowledge of caries. The corresponding rates regarding the knowledge of gingivitis were 61.2 and 41.4%, respectively. The scores of knowledge of oral infection in relation to systemic disease were 31.1% total blinds and 29.3% partial blinds. Tooth brushing ≤2 times a day was confirmed by 44.2% total blinds and 42.4% partial blinds, respectively. Awareness of oral health issues is high among the study subjects, but specific misconceptions exist. There is equality in knowledge and practice of oral hygiene among the types of blind subjects.

The advancement of new technologies for the creation of biomaterials has been inspired by the demand for materials, capable of bearing new specifications and applications. Ceramic materials based on alumina (Al2O3) and zirconia (ZrO2) is used as material of choice for fixed dental prosthesis due to their excellent properties, such as strength, corrosion resistance and biocompatibility. Full coverage zirconia-based ceramic crowns with knife edge preparations can offer a good esthetic result with minimum tooth preparation combining strength and could be considered as a treatment option in selected clinical cases. All-ceramic frameworks are fabricated from zirconium oxide and veneered in the layering technique. Additional advantages of the zirconia based all ceramic restorations are the esthetic characteristics, the biocompatibility and durability. They also show increased abrasion resistance, color and contour stability, appropriate translucency and excellent tissue response due to minimal plaque accumulation.

The coronal seal in root canal-treated teeth may be compromised depending on the accuracy of post space preparation and post cementation along with remaining gutta-percha. Root canal treatment can be compromised by endotoxins released by the coronal bacteria as a result of microleakage. The study was conducted by undergraduate students to measure the gap between the cemented post and residual gutta-percha. In total, 217 endodontically treated teeth were evaluated with intraoral peri-apical radiographs. Based on the intraoral periapical radiographic examination in the CS-R4 program, Group I had no gap, Group II had a gap of >0 to 2 mm, and Group III had a gap of more than 2 mm between the end of the cemented post and the remaining gutta-percha. In total, 40% (n = 87) of the teeth had no gap, 59% (127) had a gap of >0 to 2 mm, and 1% (n = 3) had a gap of more than 2 mm between the cemented post end and remaining gutta. Chi square test revealed a significant difference in the gap between the post and remaining gutta-percha between males and females students (p < 0.001). In terms of the gap between the cemented post end and the residual gutta-percha, the root canal treated teeth with post and core by undergraduates were clinically acceptable.

The aim of this retrospective study was to determine the prevalence of implant failure and its associated risk factors using a single implant system in our clinical setting Method: Patients who received implant treatment with a single implant system (MIS, Confident India

The placement of implants in a prosthetically driven position depends on the quantity and quality of available bone especially in the anterior region of maxilla. Implant placement and its restoration becomes clinically challenging when the alveolar ridge lacks sufficient bone volume. Additional surgical procedures are required to augment the bone deficiency in such clinical situations. Advanced procedures such as guided bone regeneration provides a conducive environment for successful placement of implants, where non-osseous cells are inhibited and osteoblast derived from the periosteum and the bones are induced to form new bone. This article presents a case report of simultaneous approach of guided bone regeneration and implant placement in the maxillary anterior with narrow ridge defect. After six months of healing period implant was aesthetically restored.
