The purpose of this study is to evaluate the effects of OSTEON, PRP and the combination of both of them on the healing of experimentally induced bone defects in rabbits. Materials and Meth-ods: Fifteen domestic rabbits were used in this study; four bone defects were made in the tibia of each rabbit. The defects were filled with OSTEON, PRP, OSTEON / PRP and the other left unfilled as con-trol. Specimens were collected at one, two and four weeks after surgery. Radiographical and histologi-cal examinations were used to evaluate healing depending of the amount of new bone formed. Results: It was found that the OSTEON / PRP combination led to a significant healing compared to other groups at first week only. On the other hand PRP alone showed better result than OSTEON alone in the three periods. Conclusion: It was concluded that PRP plasma exert a beneficial effect on healing pro-cess when added to bone substitute material OSTEON.

Aims: The aims of the study are to find the incidences, types, sides and sites of mandibular fracture accompanied with head injuries in Ninavah Governorate. Materials and Methods: Data of trauma cases were collected from general, local, private hospitals and health sectors in Ninavah Governorate with a head injury and mandibular fracture for one year duration from June 2006 to May 2007. Age, etiology, types, hospitals, sides and sites, distribution were arranged in tables, chi square and P value used for statistic analysis. Results: The total number of head injury cases was (5828). The total num-ber of fractures mandible with and without head injury was (282) cases means (4.84%) of total number of head injury cases, while mandibular fracture with head injury cases incidence was (76) cases (1.3%) of total number of head injury cases . Conclusions: Children were the most common age group affect-ed by head injury, while geriatric age group was the least. Male showed high percentage than female in a ratio about 2:1. Low incidence of association between head injury and fracture mandible which means that there is no need for delaying maxillofacial treatment. Falls from height and bullet injuries were the common cause of head injury and fracture mandible (dentoalveolar fractures showed high incidence followed by body fractures).

This study was carried out to assess the success rate of
apicectomy of anterior and premolar teeth. Out of 336 patients,
who had undergone apicectomy in a private practice between
1997–2001, only 256 patients (76.2%) completed the two
years recall visits; which was the minimum time recommended
in this study to judge whether the operation was successful
or not. The age range of the patients was 12–67 years
(mean of 34.7 years), 136 were males and 120 were females.
The overall success rate of apicectomy in this study was
89.1%. Sex of the patient had no bearing on the success rate
(p > 0.05). Highly significant influence of the patient’s age on
the success rate was observed (p < 0.01); the success rate increased
proportionally with increased age. Highly significant
influence of the type of the apicectomised tooth on the success
rate was noted (p < 0.001); upper anterior teeth showed the
highest success rate (92.1%), whereas upper premolars showed
the lowest success rate (77.4%). Periapical condition of the
tooth prior to the operation, preoperative vs postoperative obturation
of the root canal, and orthograde obturation vs retrograde
obturation were not significant factors affecting the success
rate of apicectomy (p > 0.05).
