Afolabi AO, Olojede AC, Aregbesola SB, Ogundipe OK Prevalence and perception of self reported dentine hypersensivity among dentate populations in South-western Nigeria. Tanz Dent J 2010; 16(1):29-34 Abstract Aim: To determine by questionnaire the prevalence and perception of DH in general dentate populations in south western Nigeria. Study Design: A descriptive study of self reported dentine hypersensitivity among dentate populations selected by multistage sampling technique in south western Nigeria. Subjects and methods: A structured questionnaire was administered to 373 subjects [170males, 203females, mean age 37.1 (standard deviation +/-15.8years)] selected by multistage sampling technique in 4 dental clinics in Nigeria. Analysis was done using the Statistical Package for the Social Sciences (SPSS) version 12. Results: About 61% of the subjects (60.9%, n=227) reported to have experienced DH. Most of whom were of fifth decade, and significantly more in females (64.5%) and smokers (72.7%) than males (56.5%)[p<0.03] and non-smokers (59.7%) respectively. Approximately 62% (61.9%, n=231) could identify the nature of the pain experienced. Of these 38.1%, (n=88) perceived the condition as a severe problem, 30.3%, (n=70) perceived DH as a minor problem. Forty five percent of those who reported DH had sought professional treatment. Cold was the major stimulus (42.1%) for pain. Fifteen subjects (6%) used desensitising toothpaste (Sensodyne) during periods of discomfort. Of those who sought periodontal treatment (33.8%, n=126), only 23 (6.7%) reported discomfort after treatment. Conclusion: Self reporting of DH was similar to previous studies. However, a thorough clinical examination could determine a more accurate prevalence data.

Objective: To illustrate the problems of partial anodontia and replacement of missing teeth and bone in patients with ectodermal dysplasia. Method: The illustrative case is an 11year old boy with tuberculoid shaped 11, 21 and 16 as the teeth present in the upper arch with anodontia of lower arch. Result: Upper removable partial denture and lower removable complete denture was fabricated and fitted satisfactory. Conclusion: The psychological and social embarrassment suffered by children with ectodermal dysplasia associated with missing teeth can be greatly improved with early prosthetic rehabilitation with removable prostheses. Further management with fixed prosthesis may be undertaken as they grow older.
