Dental caries results when there is an imbalance of pathogenic bacteria within these biofilms. Aim: This study sought to isolate and identify the bacterial species associated with extracted carious teeth and their susceptibility pattern towards commonly employed antimicrobial agents used at the Komfo Anokye Teaching Hospital (KATH). Methodology: A descriptive cross-sectional study carried out on thirty-three extracted carious teeth samples collected by convenient sampling from patients attending the Oral Health Directorate-KATH. All samples were collected from the 11th of March 2019 to the 6th of April 2019. Data was collected using 5 ml peptone water and a case study form. Analysis was done using SPSS version 25 and Microsoft Excel version 10. Results: Twenty (61%) samples were obtained from female patients and thirteen samples (39%) from male patients. Streptococcus spp had the highest occurrence (32.25%) with the least isolated being Pseudomonas and E. coli spp (6.45%). Antibiotic susceptibility test revealed Pseudomonas spp was resistant to all the eight antibiotics used in this study. All bacterial isolates were resistant to Cefuroxime and penicillin except Staphylococcus and Streptococcus spp. Conclusion: The commonest isolates associated with dental caries in KATH were Streptococcus, Bacillus and Staphylococcus spp. In this study most of the isolated species were resistant to common antibiotics employed in the Oral Health Directorate in KATH (amoxicillin/clavulanic, ampicillin and penicillin). From the current study the most effective antibiotic observed was meropenem (23%) with penicillin (3%) being least effective in treating infections of caries.展开更多

There was a shortfall in the supply of dental surgeons, especially in the northern half of the country. Aim/Objective: To seek for feedback from KNUST Dental school graduates over the past six about their overall assessment of the BDS courses taught during their clinical training and challenges faced in the course of their training. Methodology: A cross-sectional retrospective study of all KNUST Dental school graduates from 2012 to 2017. A structured goggle form questionnaire was developed. The Google form link was emailed to the representatives who in turn forwarded the link to their year mates. The questionnaire was filled online and submitted as requested. Results: This represented 63.0% of the entire graduates from KNUST Dental School. The male to female ratio was 1.3:1.0. The age range of our graduate was from 24 yrs (3.8%) to 32 years (1.9%). The average age was 26.3 years. 48.10% of respondents said their training was very good. The major challenges were inadequate clinical space (25.2%) and lack of materials and dental chairs for students’ clinic (27.3%). Conclusion: On the whole, the quality of the training was rated as very good even though some of the courses taught during the clinical training were rated as poor. Inadequate dental chairs, laboratory and clinic materials, supervision of student’s clinic were some of the major challenges expressed by the graduates.展开更多
