    (2010) Abiodun-Solanke, I.M.F; .Agbaje,J.O.; Ajayi, D.M; Arotiba, J.T
    Dental health workers like other workers have occupation related health problems and hazards which include neck and low back pain. Previous studies have shown that the prevalence and location of pain may be influenced by posture and work habits and as well as demographic factors. The aim of this study was to determine the prevalence of neck and back problems among dentists and dental auxillaries in private and government dental hospitals in south western Nigeria. Structured self administered questionnaire was sent to dentist and dental auxillaries by randomly selecting 3 out of the 6 state capital from the southwestern Nigeria. Participants included those in private clinics, teaching hospitals and general hospitals. The questionnaire was composed of respondents biodata, questions about specific information on neck and back pain and routine practice posture while working at chairside. The total number of properly filled questionnaire was 210 with a male to female ratio of 1.04:1. Respondents included 147 dentists, 37 dental surgeon assistants (DSA), 14 dental therapists and 12 dental technologists. Prevalence of back and neck pain among the respondents was 88.1% and 81.9% respectively. Among the male respondents, the prevalence of back pain was 86.9% and 89.3% in female while for neck pain , the prevalence was 83.2% in male and 80.6% in female. Within the different professional groups, the prevalence of back pain was highest among the DSA(89.2%), closely followed by the dentists(88.4%), then therapists(85.7%) and least among the technologists(83.3%). For neck pain, the prevalence was highest among therapists followed by technologists , dentists and least among the DSA. More females missed work due to back and neck pain than males. There is therefore the need to address ergonomic issues and change the way dentistry is practiced.

    Survival of glass fiber post retained endodontically treated teeth preliminary report
    (2012) Gbadebo, S.O.; Ajayi,D.M.; Abiodun-Solanke, I.M.F; Sulaiman, A.O.
    Background: The use of fiber reinforced composite post in restoration of endodontically treated teeth have been found to prevent irreparable root fracture and the fact that the post is bonded to the root giving a monobloc restoration, also strengthens the tooth. This preliminary study aimed to evaluate the survival of endodontically treated teeth with compromised coronal tooth structure restored with glass-fiber posts after 6 months. Methodology: Twenty endodontically treated teeth with less than 50% coronal tooth structure, were assessed and restored with glass fiber reinforced post cemented with dual cure composite and porcelain fused to metal crown. Patients were recalled and the teeth re-assessed at 3 and 6 months to evaluate their survival. The criteria for success included post and core in situ with no displacement or detachment of the post, no crown or prosthesis decementation, no post, core, or root fracture and absence of periradicular conditions requiring endodontic retreatment. Result: Eighteen teeth were available for review at both 3rd and 6th months out of which none had postcore-crown fracture. One tooth (5%) had minimal crevice on probing the margin at 6 month’s review, while another tooth had < 1mm mobility of the crown during the same review period. Conclusion: Within the limitation of the study, there was an excellent performance of the teeth restored with glass fiber post with respect to post –core- crown and root fracture at the end of the 6months recall visit.
