Item Prevalence and Distribution of Cracked Posterior Teeth among Adult Patients(2020) Ogundare, T.O.; Ajayi, D.M.; Idon, P.I.,; Bamise, C.T.,; Oginni, A.O.; Esan, T.A.Background: There are challenges in detection and prevalence of cracked teeth, especially in asymptomatic cases. This underestimates the actual prevalence and possibility of preventive restorative treatment. Objectives: To determine the prevalence and distribution of cracked posterior teeth among adult patients attending the dental clinic of OAUTHC, Ile-Ife, Osun State, Nigeria. Materials and Methods: A cross sectional study where consecutive patients aged 18 years and above were examined for the presence of cracked posterior teeth over a period of one year (May 2016-April 2017). The teeth were initially examined with the naked eye. Thereafter, transillumination, methylene blue dye and magnifying lens were used to aid detection of more cracks. Data was analyzed with the IBM Statistical Package for Social Sciences (SPSS) for Windows (version 21.0). Level of significance was set at p ≤ 0.05. Results: Out of the 64,370 posterior teeth examined for cracks in 3345 patients, 264 were diagnosed as cracked in 152 patients, giving a patient prevalence of 4.5% and tooth prevalence of 0.4%. Amongst the 152 patients, the prevalence was 9.1%. There was a slightly higher male preponderance while cracked tooth was observed to increase with age (p = 0.007). The skilled (56.6%) and those that attained tertiary education (77.6%, p = 0.023) had more cracked teeth. Mandibular first molar (19.7%) was the most frequently cracked tooth type. The cracks were usually centrally placed (91.7%) and run in a mesiodistal direction (61%). Transillumination (44.7%) detected more cracked teeth. Conclusion: Prevalence of cracked tooth was observed to be low with a slightly higher proportion in male and the figure increases with age. Mandibular first molar was the most frequently cracked tooth while transillumination was the most useful diagnostic tool. Most cracks ran in the mesiodistal direction and fracture lines were usually centrally placed.Item Self Reported Musculoskeletal Pain Among Dentists(2011) Abiodun-Solanke I.M.F; Ajayi, D.M.; Agbaje J.O.; Arotiba J.T.Background: Musculoskeletal complaint is an important health issue among dentists. Given the significance of this topic, we considered it necessary to investigate the prevalence and impact of musculoskeletal disease among Nigerian dentists Aim/Objectives: To assess the work- related complaints among dentists with the specific objective of finding out the prevalence of neck and back pain among dentists Materials and Methods: A structured questionnaire was sent to tivo hundred and fifty practising dentists in 3states capitals which were randomly selected from South - Western Nigeria. Participants were drawn from general hospitals, private clinics and teaching hospitals. Participants included general practitioners, specialists in restorative dentistry, oral and maxillofacial surgery, child oral health (pediatric and orthodontists), period ontology and oral pathology. Results: The response to participate in the study was 66.7% out of which 60% correctly filled questionnaire was analyzed. The mean age of participants was 32.8 ± 6.8years (SD) with a male to female ratio of 1.4:1. Prevalence of back pain was 89.6% while that of neck pain was 81.3%. Back pain was found to be higher in females (91.7%) compared to males (88.1%) while neck pain was higher in males (82.1%) compared with to females (80.0%). Back and neck pain were highest in those who worked 8-12 hours per day. Back pain was highest(94A%) in those who had practiced for 6-10 years while those who had practiced for more than 20 years reported *the highest percentage of neck pain. Respondents in restorative dentistry all had back pain at one time or the other over a period of twelve months, while neck pain was highest among respondents in child oral health(91.7%) . 43% of respondents perform their procedures standing, while 38% use the sitting position and 19% alternate between standing and sitting position. Other work related complaints reported by the dentists include headache, shoulder pain, pain around the wrists and paresthesia of the fingers of the dominant hand More respondents missed work due to back pain irrespective of the gender. 17 respondents sought medical help due to neck pain out of which 8(47.1%)) received only analgesics while among those who sought medical attention due to back pain, 7(63.7%) received analgesics only. Conclusions: Occupational related health problems among Nigerian dentists were common. There is a substantial need and demand for further training in occupational health and safety among dentists.
