Aim: To review the pattern of failure and the associated factors of the post retained restorations done over ten years.Method: A retrospective cross-sectional study, which audited the record of post-retained restorations. Data including biodata, tooth type, post type, post size, luting cement, and failure were extracted and analyzed. Statistical significance was set at p value ≤0.05. Results: There were 210 participants (M=106, F=104). Stainless steel para posts mainly were used (91.8%); with size three (3) being the highest (23.8%) recorded. Dual cure composite was mainly (78.1%) used for the post cementation. There were 27 (12.8%) cases of failure of post retained restorations of which post-fracture combined with post and crown dislodgement had the highest (52%), with the tooth fracture being the least reported (14.8%). Post fracture only was commoner in males (66.7%). The majority (81.5%) of the failure was seen in the para post group, with no tooth fracture reported for the fibre post. Conclusion: Post and core placement is a common procedure for restoring endodontically treated teeth with a reduced coronal structure for the main purpose of retaining the core and, ultimately, the restoration. Stainless steel post was the commonest used, and post-fracture combined with dislodgement of post and crown constituted the most prevalent failure reported.

Background: Dentine hypersensitivity is a common presentation of cause of pain and or discomfort with mastication which has been shown to affect the quality of life of the affected individual. It is also a common cause of presentation at the dental clinics. However, the cause, diagnosis and possible management to give relief can be a dilemma for the clinician who at times may wonder if the sensation the individual is presenting with, is real or imagined.Aim: The purpose of this paper was to review dentine hypersensitivity in view of causes, diagnosis and management.Methodology: Articles used were found by searching the key words: dentine hypersensitivity, tooth wear lesions, desensitization, gingival recession, treatment of hypersensitivity.Result: There are a variety of causes of dentine hypersensitivity with a variety of ways to manage and provide adequate treatment, but the condition must be well understood.Conclusion: Many options of treatment are now available to eliminate the pain from dentine hypersensitivity and thus improving the quality of life of these patients because the sensitivity they experience is real.Keywords: dentine, hypersensitivity, tooth wear, desensitization, quality of life

Tooth discoloration is an aesthetic problem that is linked to a variety of causes and it could be a source of embarrassment, leading to reduced self-esteem.To determine the prevalence of self reported tooth discoloration and the distribution of the different intrinsic tooth discolorations.A retrospective study that reviewed the distribution of tooth discoloration reported by patients that presented for treatment of tooth discoloration at conservation clinic of the dental centre University College Hospital, Ibadan between December 2011 and December 2014. Data collected from patients' case files included patients' demographics, type of tooth discoloration as diagnosed by attending consultant and treatment offered. Data were analyzed using SPSS version 20. Frequencies and means were used for continuous variables while chi square was used to compare the categorical variables. P value was set at ≤ 0.05.One hundred and thirty six patients reported tooth discoloration as their major reason for presentation at the clinic. The patients were between age 16-75 years with mean age of 35.62±14.31 years and male to female ratio of 1:1.13. Prevalence of reported tooth discolouration during the study period was 9.8%. Pulpal necrosis was the most reported cause of (86.8%) tooth discolouration, while fluorosis was the least (0.7%) reported. Non vital tooth bleaching was the most common treatment (72.1%) offered for tooth discoloration. No significant comparison was observed between gender and type of tooth discoloration, p=0.088.Pulpal necrosis is a major cause of discoloration which leads to reduced self esteem. There is need to improve on dental awareness on causes of tooth discoloration for prevention and early presentation for management.
