    Comparison of the dimensional stability of alginate impressions disinfected with 1% sodium hypochlorite using the spray or immersion method
    (Nig Quarterly J Hosp Med, 2007) Oderinu, OH; Adegbulugbe, IC; Shaba, OP
    Objective: To determine and compare the dimensional stability of alginate impressions disinfected with Sodium hypochlorite using the spray and immersion methods. Methodology: Alginate impressions of a master model of truncated metal cones were made and disinfected with 1% sodium hypochlorite constituted from 3.5% household bleach using the spray and immersion technique for 10;20 and 30 minutes. Impressions were cast in dental stone and the linear dimensional differences between the inter-abutment distances were measured with an electronic caliper. One sample T test and percentage differences were calculated. Result: There were no statistically significant differences in dimensions of alginate impressions of the control and those disinfected by either spraying or immersion methods when compared with the master model at 10 minutes. However, there was a statistically significant difference at 20 and 30 minutes. The spray technique showed the least percentage difference from the master model. Conclusion: Disinfection of alginate impressions with 1% sodium hypochlorite constituted from commercially available household bleach by the spray or immersion techniques for ten minutes will produce casts with minimal dimensional changes.

    Dens Invaginatus: Prophylactic Management
    (Nig Dental Journal, 2007) Oderinu, OH; Adegbulugbe, IC; Agbaje, LO
    Densinvaginatus is thought to be asa result of distortion of the enamel organ during tooth development and the subsequent protrusion of a part leading to the formation of a linear enamel canal that ends at the cingulum, or at the incisal border, producing an irregular crown shape. food debris may become packed in this area with resultant caries and pulp necrosis and periradicular inflammation. The permanent maxillary lateral incisors are the most commonly involvedteeth and bilateral involvement is not unusual. Case Report This is a report of bilateral involvement of the maxillary incisors with associated carious involvement of the coronal pits in a 43year old man with a high caries index. Composite filling of the palatal pits of the involved teeth was done as a prophylactic treatment to prevent carious exposure of the pulp and subsequent periradicular pathology. Conclusion. Prophylactic filling of the coronal pit is recommended to avoid pulpal and periradicular complications that may warrant extensive and expensive treatment or even loss of the involved tooth.

    Evaluation of Linear Dimensional Stability of Various Combinations of Dental Stone and Plaster
    (Nig Quarterly J Hosp Med, 2011) Adegbulugbe, IC; Oderinu, OH; Shaba, OP; Oremosu, OA
    Background: It has been observed that due to the cheaper cost of dental plaster compared to dental stone, casts on which most of the dental prostheses and appliances were being fabricated in various laboratories were often mixtures of dental stone and dental plaster in order to reduce production cost. Objective: To evaluate the dimensional stability of various combinations of Dental Stone and Dental Plaster mixtures used to make dental casts. Methods: Alginate impressions of a master model of truncated metal cones were made and casts were produced by pouring with various combinations of dental stone and dental plaster mixtures. The linear dimensional differences between the inter-abutment distances on the casts were measured with an electronic calliper. One sample t-test and percentage differences were calculated. Results: Dimensional variations for the distances measured using either 50% dental stone or 25% dental stone with plaster were statistically significant (p d" 0.05). Mixture of 75% dental stone and 25% dental plaster produced casts with no statistically significant dimensional variation from the master model (p en0.05). Conclusion: A mixture of 75% dental stone and 25% dental plaster could be used for procedures not requiring very accurate replica like mounting of teeth for dental training and for study models.

    Fixed Bridge Prostheses Management of Epileptic Patients.
    (Nig Quarterly J Hosp Med., 2012) Umesi, DC; Oderinu, OH; Adegbulugbe, IC; Oremosu, OA
    Background: Epileptic patients in the course of seizures may suffer damage to or loss of teeth and other oral tissues. Moreover, they are at great risk during their seizures from aspiration of foreign bodies such as removable dental prosthesis or fragments of prosthesis. It is therefore, necessary to provide them a tooth replacement option that would" be safe and not constitute a source of danger in the course of seizures. Case Reports: Two patients are presented in this report that lost teeth as a consequence of trauma sustained during seizures. They both had porcelain-fused-to-metal (ceramo-metal) fixed bridge prostheses fitted to replace the missing teeth. The fixed bridges have been in service for seven years without damage despite the fact that the patients still have seizures at the same frequency as prior to treatment that are often associated with trauma to oral' tissues. Conclusion: Fixed bridge prostheses are a viable tooth replacement option for epileptic patients that do not pose any additional danger of being dislodged, swallowed or aspirated in the course of a seizure.

    Prevalence of self reported hypersensitive teeth among a group of Nigerian undergraduate students
    (Niger Postgrad Med J, 2011) Oderinu, OH; Savage, KO; Uti, OG; Adegbulugbe, IC
    AIMS AND OBJECTIVES: To determine the prevalence of self reported hypersensitive teeth and relate this to the frequency and quantity of consumed carbonated drinks among a group on Nigerian dental and medical undergraduate students and the management of the condition by the students. MATERIALS AND METHODS: Self administered questionnaire was used to collect information on demography, consumption of carbonated drinks, hypersensitivity of teeth and its management from students. Students were chosen using stratified sampling method. Each level of study was taken as a stratum and students were then chosen from each stratum by systematic sampling. RESULTS: A total of 387 questionnaires were returned. Hypersensitivity of teeth was reported by 33.8% while 52.7% of them were bothered about the condition, half (50.0%) of those bothered by the condition had done nothing about it. About a third (29.7%) of the respondents, (16.3% consumed once daily and 13.4% consumed 2/more times daily) consumed carbonated drink at least once a day. A great majority (77.0%, 17.2%) either consumed 1-2 bottles (35cl/bottle) or 1-2(30cl/glass) of carbonated drinks per day respectively. Tooth sensitivity occurred more commonly among students who consumed carbonated drinks most frequently (i.e. 2 or more times a day) but there was no significant statistical association between frequency and quality of carbonated drink consumption and self-reported dentine hypersensitivity. (p>0.05) CONCLUSION: Hypersensitivity of teeth was common among the students studied but request for treatment was poor. There is need for increased public awareness on prevention and management of common dental conditions.
