(2011) Ajayi,D.M.; Abiodun‑Solanke,I.M.; Sulaiman, A.O; .Ekhalufoh, E.F.
Background: Various aspects of dental trauma have been studied worldwide. Most of these were among children and adolescents. However, studies involving the adult population with traumatized anterior teeth are few. Objectives: The objectives of this study were to report the pattern of trauma to anterior and posterior teeth among the late adolescent and adult patients seen at the Dental Centre, University College Hospital, Ibadan, Nigeria, the time lapse between trauma and patient presentation, reasons for dental consultation, and the type of treatment received. Materials and Methods: Data were extracted from the dental records of 146 patients with dental trauma that presented between May 2001 and June 2006. Results: One hundred and forty six patients were studied (87 males, 59 females) Males sustained injury more than females. The highest occurrence of trauma was in the age group of 25-34 years and least in the >65 years. Falls accounted for 34.3% of causes followed by RTA (19.2%). Enamel-dentine fracture was the most common type of injury, seen in 73 (38.6%) of the traumatized teeth, 5 were avulsed and 20 posterior teeth had cuspal fracture. All the cases of avulsion and most (83.3%) of root fracture presented within 1 week of injury while teeth that presented late had pulpal necrosis. 22% of the patients presented within 1 week of injury while 13.7% came after 10 years. Conclusion: There was late patients’ presentation with average duration of trauma before presentation being 4.6 years; however the more severe the outcome of trauma, the earlier the presentation. Poor esthetics followed by pain were the main complaints at presentation.
Dental caries prevalence and bilateral occurrence in premolars and molars of adolescent school children in Ibadan, Nigeria
(2015) Denloye, O.O.; Ajayi,D.M.; Popoola, B.O.
The aim of the study was to determine the prevalence of dental caries in premolars and molars of adolescent school children in Ibadan, Nigeria with a view of comparing findings from this study with previous African studies. A cross section of 12-19 year-old school children from the five local government areas in Ibadan were examined over a period of three months by two examiners (OD and DA), using the WHO criteria for diagnosing dental caries. Only premolars and molars were examined but the third molars were excluded because they were not fully erupted in most children. The mean age of the children under study was 16.2 ± 0.83 years. Dental caries was detected in 10.8% of the children. Overall, 225 teeth had dental caries, out of which 13.3% were premolars while 86.67% were molars. Among the molars, first molars were mostly affected by caries (68.72%) while 31.28% second molars were affected. Second premolars were more affected by caries among the premolars. Also bilateral caries occurrence was highest in the mandibular first molars. In conclusion since the first molars were the most vulnerable teeth to decay, caries preventive programs on them need to be drawn up.
Randomized clinical study comparing metallic and glass fiber post in restoration of endodontically treated teeth
(2014) Gbadebo, O.S.; Ajayi,D.M.; Dosumu,O.O.; Shaba, P.O.
Background: Post-retained crowns are indicated for endodontically treated teeth (ETT) with severely damaged coronal tissue. Metallic custom and prefabricated posts have been used over the years, however, due to unacceptable color, extreme rigidity and corrosion, fiber posts, which are flexible, aesthetically pleasing and have modulus of elasticity comparable with dentin were introduced. Aim: To compare clinical performance of metallic and glass fiber posts in restoration of ETT. Materials and Methods: 40 ETT requiring post retained restorations were included. These teeth were randomly allocated into 2 groups. Twenty teeth were restored using a glass fiber-reinforced post (FRP) and 20 others received stainless steel parapost (PP), each in combination with composite core buildups. Patients were observed at 1 and 6 months after post placement and cementation of porcelain fused to metal (PFM) crown. Marginal gap consideration, post retention, post fracture, root fracture, crown fracture, crown documentation and loss of restoration were part of the data recorded. All teeth were assessed clinically and radio-graphically. Fisher’s exact test was used for categorical values while log-rank test was used for descriptive statistical analysis. Results: One tooth in the PP group failed, secondary to documentation of the PFM crown giving a 2.5% overall failure while none in the FRP group failed. The survival rate of FRP was thus 100% while it was 97.5% in the PP group. This however was not statistically significant (log-rank test, P = 0.32). Conclusion: Glass FRPs performed better than the metallic post based on short-term clinical performance.
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.
The fluoride content of drinking water and caries experience in 15 – 19 year old school children in Ibadan, Nigeria
(2008) Ajayi,D.M.; Denloye O.O; Dosumu O.O.
Fluoride, a trace element with anticariogenic benefit may either occur naturally or be added to drinking water sources. This study aimed at determining the fluoride level of the different drinking water sources in Ibadan, Oyo State, Nigeria and to relate this with the caries experience of secondary school children in the city. Sixteen samples of the drinking water sources from various locations in the five local government areas of the city were analysed for fluoride concentration. The locations were selected around the vicinities of the secondary schools used for caries study. Nine hundred and fifty five students aged 15-19 years randomly selected from eleven secondary schools in Ibadan metropolis were examined for dental caries over a period of 4-5 months. Only teeth with obvious cavitations were recorded as being carious using the WHO standard method. Teeth grossly covered with calculus and third molars were excluded. No radiograph was taken. The fluoride level of the different water sources was between 0.02 and 0.03ppm. Forty-four (4.6%) of the children had dental caries. There was no statistically significant difference between either DMFT and gender (t = 0.67, p = 0.91) or DMFT and age (F=1.488, p=0.224). However, females had a slightly higher mean DMFT than males and the highest mean DMFT (2.67 + 1.15) was found among the 19- year- old children. Twenty-three (52.3%) of the students with caries had only one carious tooth while only two had four carious teeth each. In conclusion, both the fluoride level and caries prevalence were low.
