However, it cannot be used for fabrication of dental implants due to its inertness, low biocompatibility and weak resistance to corrosion. A composite coating of titanium oxide /graphene oxide has been prepared for stainless steel to improve its biological properties. Stainless steel discs were polished, cleaned and pre-treated with a mixture of HNO3 and HF acid for 15 min. The composite coating composed of TiO2 produced by sol-gel technique and doped with 0.75 wt% graphene oxide. XRD, SEM-EDX and AFM were employed to characterize the composite coating. The anti-bacterial action of the composite coating was investigated against S. aureus and E. coli. The corrosion resistance of coated and noncoated samples was assessed in SBF using electrochemical technique. Cytotoxicity was assessed using osteoblast-like cells. The wettability was determined by contact angle, and bioactivity assessed by immersion in SBF. The results revealed that the composite coating was dense with few micro-cracks, and was not cytotoxic to osteoblast-like cells. The composite coating reduced bacterial colonies and the corrosion rate of the steel was improved. The wettability of the sample was increased with the composite coating and apatite formation appeared after 21 days.

However, PEEK lacks bioactivity and antibacterial action. In a series of experiments designed to enhance the surface properties of PEEK, we present a nanohydroxyapatite (nHA) and graphene oxide (GO) composite as a coating for PEEK‐based dental implants to improve biological properties and antibacterial action. PEEK discs were polished, cleaned, and coated with the composite consisting of nHA particles doped with 0.75 wt% graphene oxide by a micro‐emulsion technique according to patent US8,206,813. X‐ray diffraction, field emission scanning electron microscopy‐energy dispersive spectroscopy, and atomic force microscopy were utilized to characterize the composite coating. The wettability of the coated and non‐coated samples was assessed by optical contact angle measurement. Antibacterial action of the composite coating was explored against S. aureus and E. coli and cytotoxicity deter...

Successive patients with impacted mandibular wisdom tooth were recruited. Winter's classification was used to classify impacted teeth. Surgical removal of impacted teeth was done using local anesthesia. The effect of age, duration of surgical operation and pattern of impaction on post-operative pain and trismus was studied after 3 and 7 days. Visual analogue score (VAS) was used to assess pain, trismus was measured as the inter-incisal distance using manual caliper and duration of surgical procedure was defined as the period between incision and finishing of suturing. Seventy nine patients with age ranged 15 to 41 years were recruited. The highest percentage were male gender (57%). The highest pain VAS score was recorded in the age group (30-41) after 3 days and the lowest mouth opening was seen in the sa...

This lesion has a tendency to reoccur after surgical excision. Materials and Methods: A total of 28 patients underwent surgical excision of pyogenic granuloma in the period from September 2014 to May 2016. Two surgical techniques were used to remove pyogenic granuloma: simple excision with root planing and modified excision with deep curettage. Results: Females (54%) were slightly more predominant than males (46%). The upper and lower jaws were almost equally affected by the lesion with more predilection toward the posterior region. The size of the lesion ranged from 0.5 to 3 cm in diameter with slow-growing rate. Rural residents were more affected (57%) than urban people. The lesion appears clinically as a small red mass with sessile base, and these clinical features were similar in pregnant and nonpregnant women. The recurrence rate was 14.8% and seen only in patients treated by simple excision. Histop...

Patients and methods: A total of 317 students (140 males and 177 females) age ranged 20-25 years were recruited in this study. Each student was asked to open his/her mouth as wide as possible. The distance between the incise edge of upper right central incisor and the opposing tooth of the lower jaw was measured using a manual caliper. Results: The maximum mouth opening was 58 mm ±7.21 and 42 mm ±6.98 for males and females, respectively. The maximum mouth opening of males is significantly larger than that of female (P= 0.000). For males the highest value of mouth opening was observed in the age 23 years and a negative and insignificant (P=0.472) correlation was seen in the ages (24 and 25 years). For females the maximum mouth opening was noticed in the age of 20 years and a significant decreased (P=0.000) of ...

However, there is considerable debate about its effect on wound healing and inflammatory response. Materials and Methods: PubMed, Google Scholar, Scopus data base, and manual search were performed to find out articles on the use of PRP in dental and oral surgery using keywords such as PRP , oral surgery, dental surgery, lower wisdom teeth, periodontal pocket, dental implant, tooth socket preservation, dry socket, cystic lesion, and ridge augmentation. These articles discussed the use of PRP (after surgical removal of wisdom teeth, treatment of periodontal pocket, ridge preservation, implant stability, prevention of dry socket, treatment of bony defect after cystic removal, and ridge augmentation). Results: Twenty-seven articles were found on the usage of PRP in dental and oral surgery. Six articles on the use of PRP after surgical removal of lower wisdom teeth, five articles in the treatment of periodontal pocket and implant stability, four article in ridge preservation, three articles in prevention of dry socket and two articles on the use of PRP after cystic removal and ridge augomentation. Conclusion: PRP enhanced bone regeneration and soft-tissue healing aftery lower wisdom tooth surgery. It decreased the depth of periodontal pocket, maintained implant stability, preserved ridge height and prevented dry socket. However, PRP had no effect on pain, swelling, and bleeding. There is no justification for the impact of PRP on bone augmentation and healing of bony defect after cystic removal of the jaws. More studies should be carried out to support the usage of PRP in oral and dental surgery.
