Aim: The aim of this study were to assess the oral hygiene knowledge and practice among secondary school students in Owerri Municipal Area, Imo State, Nigeria. Study Design: This study employed a descriptive survey design. Place and Duration of Study: This study were carried out in Secondary Schools in Owerri Municipality, Imo State, Nigeria within September 2014 and June 2015.  Methodology: Data were collected using structural pretested questionnaire administered to 500 randomly selected consenting respondents (students) with 251 female and 249 male students. Data were analyzed descriptively and inferentially using SPSS version 20. The hypotheses were tested at 0.05 level of significance and data generated were subjected to percentage findings presented by the use of tables. Results: The results affirmed that 84% of the respondents had oral hygiene knowledge, 78% were of the opinion that major source of oral hygiene knowledge were parents/guardians, and 20% of the respondents acquiring information through their school teachers. It was noted that 44% of the respondents had good oral hygiene practices in Secondary School in Owerri Municipal Area, Imo State, Nigeria. The result of the statistical analyses shows that there was a significant relationship (342.624; P = .001) between the age of the students and the knowledge of oral hygiene, there was significant relationship (337.910; P = .001) between major source of oral hygiene information and the knowledge of oral hygiene and there was a significant relationship (390.988; P = .001) between major source of oral hygiene information and the practice of oral hygiene. The study therefore provided information on oral hygiene knowledge and practice in secondary school in Owerri Municipal Area, Imo State, Nigeria. Conclusion: It can be recommended to Students/Parents/Government and School Teachers to embrace the idea that oral diseases can be prevented or mitigated by individual action of daily brushing and other oral hygiene related practices to pervert the negative oral health consequences.

Aim: This study is aimed at ascertaining the level of knowledge and challenges associated with the practice of dental implants among dental practitioners in selected hospitals in South East, Nigeria. Study Design: the study employed cross sectional study design. Place and Duration of Study: The research was carried out within six months (September 2018 to March 2019) in selected hospitals and clinics in South-East, Nigeria. Methodology: Data were collected using structural pretested questionnaire administered to 117 purposefully selected consenting respondents (Dental Professionals). Data were analyzed descriptively and inferentially using SPSS version 20. The hypotheses were tested at 0.05 level of significance and data generated were subjected to percentage findings presented by the use of tables. Data collected were analyzed and discussed. Result: the result affirmed female respondents were more than male with 59.0%, indicating Dental Therapist as majority in proportion with 64%. On quality of implant shows 64.9% and 56.4% on comfort and function which indicates it as a good quality, 64.9% poor availability and 49.6% awareness and knowledge. While inferentially, using Pearson Chi-Square showed a significant relationship of 177.552; df = 16 @ P=0.05 between profession of respondents and knowledge of dental implant materials/devices types while using ANOVA showed a significant relationship with F =42.147; df =4 @ P=.05; knowledge of dental implant materials and assessment of dental implant to aesthetics on oral cavity, F =77.760; df =4 @ P=.05 and  knowledge of dental implant materials and assessment of dental implant to retention on oral cavity, F =54.985; df =4 @ P=.05. Conclusion: from the results obtained, accredited dental implant as an appliance capable of obviating most of dentures shortcomings which depends on contra-indication and indication of it, and its challenges in the profession. Although there are challenges associated with dental implant awareness and application in Nigeria. Recommendations and tips on successful further studies were given.

Dental inlay wax is a mixture of several waxes, usually containing paraffin wax, ceresin wax, beeswax and other natural and synthetic waxes. It is used to prepare patterns for gold or other metallic materials in the fabrication of inlays, crowns and bridges. Inlay wax is used for the same purpose as casting wax in the formation of pattern mostly for metallic casting in Dental technology. This study aimed at producing dental inlay wax using locally sourced materials in Enugu, Nigeria. The research was carried out between July to September, 2018 in Enugu, Nigeria. The study adopted a three phased experimental approach using the same procedures but different weight compositions. Structured, pretested Product Evaluation Data Sheet was used to evaluate the product by selected Practicing Dental Technologists in Enugu State, Nigeria. The resultant wax from experiment III with the following composition: 60g Paraffin wax, 5g Beeswax, 25g Carnauba wax, 10g Ceresin wax and (35g) of green ketchup colorant gave the best result. Its properties are comparable to the conventional Dental Inlay wax. There was significant agreement among the respondents in the smoothness of the product (40%); excellent dimensional stability and product effectiveness (40%); flow and burnout of the product (35%), and color stability of the product (45%). These findings suggests that dental inlay waxes can be produced locally in Enugu, Nigeria. Therefore, more attention needs to be paid in the production process, which will facilitate easy practice of Dental Technology, and also conserve huge foreign exchange being spent in the importation of inlay wax in Nigeria.
