Background: In developing countries, there is an increase in awareness among the population regarding dental implant treatment. However, there is paucity in studies on the relationship between patients' biographic information, and different aspects of dental implant treatment. Aims: This study's purpose is to determine the influence of Iraqi patients' age and gender on various clinical aspects in dental implant treatment. The recorded data included: patient age, gender, implant zone, implant timing, implant side, dental implant system, sinus lift, bone augmentation, implant length, and implant diameter. SPSS Ver. 25 was used to perform the statistical analysis. Methods and Materials: Biographic data of 196 Iraqi patients who attended a private dental implant center in Baghdad from 7.1.2016 to 30.4.2020 was recorded. During this period 348 dental implant procedures were completed. Results: There was a highly significant negative relationship (p=0.006) between implant length and patient's age, and a significant positive relationship (p=0.028) between implant size and patient's age. A statistically significant relationship (p=0.013) was found between the patient's age and dental implant zone and dental implant timing (p=0.016). A significant difference was found between the two genders in terms of dental implant timing (p=0.017). Conclusion: females are better candidates for dental implant treatment. Older patients seem to benefit more from shorter, and, subsequently, wider dental implants. Also, older patients tend to have lower anterior dental implants.

Oral infections are usually caused by poly bacterial. Approximately 60% of oral infections are caused by joint aerobic and anaerobic bacteria; 35% caused by anaerobic bacteria and 5% due to aerobic bacteria. When aerobic bacteria are involved, Gram positive aerobic cocci are the most common aerobic species involved in oral cavity infection (e.g., Streptococci (e.g., Streptococci "species" (spp), Staphylococci spp). In cases of anaerobic and/ or mixed infection Streptococci spp, Peptostreptococci spp and gram-negative anaerobic bacilli (Prevotella spp, Porphyromonas spp, Bacteroides spp, and Fusobacterium spp) are involved. [1,2].It has been hypothesized that synergism between more than one type of bacteria in a particular infection plays a key role in their pathogenicity. Accordingly the target of the antimicrobial control Local application of natural antimicrobial products on oral infection site can be considered useful alternative to common antibiotics. Cinnamomum zeylanicum (C.Z) has been found to be effective against both types of bacterial (Gram-negative and Gram-positive bacterial), which play roles in human infections responsible for human infectious diseases. This study aimed to assess the efficacy of (C.Z) antibacterial activity on isolates from orofacial infections. The antibacterial activity of crude (C.Z) ethanol extracts on four types of oro-facial infection microorganisms was studied; ciprofloxacin an antibiotic was used as positive control. The Results showed All four bacterial isolates (Staphylococcus aureus, Escherichia coli, Peptococcus and S. Mutans) were sensitive towards the ethanol extract of Cinnamomum. However, the maximum antimicrobial activity has been shown against Staphylococcus aureus. This study is the first of a series of studies to produce Cinnamon extract for local control of oral facial infections. Conclusion and clinical significance is Crude (C.Z) ethanol extract effective against aerobic, anaerobic, gram positive and gram negative oral pathogens. The extract might be employed to make an effective spray or ointment for orofacial infection.for such infection will be the synergism between key offending organisms and there is no need for specific medication for every involved bacteria in the infection process [1,3].Recently there has been more focus natural materials, more specifically aromatic plants with wide biological medicinal applications [4][5][6]. Among them is Cinnamon, which is a spice, commonly used in food. The aroma its oil has makes it useful in food industry [7]. One of Cinnamon species is C. zeylanicum. C. zeylanicum contains eugenol [8][9][10], in addition to it Antimicrobial property of C. zeylaincum is attributed to the presence of cinnamyl acetate, methoxy cinnamaldehyde (MOCA) and other volatile compounds [11,12]. Among cinnamon extracts, essential oils and components have been identified for their activity against

Introduction: The role of the lower third molars in the lower incisors crowding has been debated for more than a century. Significant disagreement exists among practitioners, including both orthodontists and oral and maxillofacial surgeons whether the third molar causes mandibular anterior crowding. Aim of study: The purpose of this study is to ascertain whether the lower third molars can contribute to the occurrence or aggravation of crowding. Materials and methods: A sample of 131voluneteer (67 males and 64 females) aged 18-25 years were included in the 1st ,2nd, ,3rd ,4th and 5th stage of college of dentistry /Tikrit University was chosen, the sample was divided into three main groups consisted subjects who had mandibular third molars that were either impacted, erupted into function or agenesis. Results: The study showed that 70(53.4%) volunteer s out of the 131 have impacted lower 3rd molar, 52(39.7%) volunteers have erupted lower 3rd molar, while 9(7.6%) volunteer have agenesis of the 3rd molar. Conclusion: The crowded group revealed a higher percentage of impacted third molar while lowest percentage of third molar agenesis.
