Dentine hypersensitivity and associated factors: a Nigerian cross-sectional study.

Introduction: Prevalence of dentine hypersensitivity (DH) may be on the increase as a result of changing lifestyles. This study aimed to assess the prevalence of DH and relative importance of associated factors in 18-35 year old Nigerians and compare to findings from a similar European study.

Methods: Following ethical approval, 1349 subjects from the six geopolitical zones in Nigeria participated in this cross sectional study.

Knowledge, diagnosis and management of dentine hypersensitivity: a national survey of dentists in Nigeria.

Aim: To assess the knowledge of Nigerian dentists regarding dentine hypersensitivity (DH) and their methods of diagnosis and management.

Methods: A cross-sectional questionnaire-based study of dentists practicing in all six geopolitical zones of Nigeria was conducted. The questionnaire focussed on participant's demography, exposure to patients with DH, knowledge-based questions, diagnosis and management of DH.

Pattern of traumatised anterior teeth among adult Nigerians and complications from late presentation.

Background: The objectives of this study were to determine the prevalence and pattern of traumatic dental injury (TDI) among adults presenting in a tertiary health care facility in Nigeria, the time interval between injury and presentation in the hospital, the reasons for seeking treatment, and the complications arising due to late presentation.

Methods: Information obtained from history taking and clinical examination included Patient's demographics, the when, where, and how of the injury, previous history of trauma, time elapsed between injury and presentation at the hospital, reason for seeking treatment, tooth/teeth involved, sensibility, tenderness to percussion, mobility, presence of discolouration, swelling, sinus tract, and mobility. Radiographic findings such as periapical radiolucency, pulp canal obliteration, and root resorption were also documented.

Comparison of pattern of failure of resin composite restorations in non-carious cervical lesions with and without occlusal wear facets.

Objectives: Many studies have reported the clinical problems associated with resin composite restorations in NCCLs. None has compared these clinical problems in NCCLs with and without occlusal wear facets. The present study sets out to determine the proportion of NCCLs that presents occlusal wear facets, and to compare the failure pattern of resin composite restorations in NCCLs with and without occlusal wear facets.

Root canal treatment and prevalence of apical periodontitis in a nigerian adult subpopulation: a radiographic study.

Purpose: To evaluate the frequency, distribution and quality of root canal treatment in an adult Nigerian subpopulation and to determine the prevalence of apical periodontitis.

Materials And Methods: The periapical status and length of root fillings of 756 patients attending Obafemi Awolowo University Teaching Hospital, Ile-Ife, Nigeria for the first time were evaluated using full mouth periapical radiographs. The length of the root canal filling was considered 'adequate' if it was ≤ 2 mm from the radiographic apex, 'under-filled' if it was > 2 mm short of the apex, and 'overfilled' if filling material extended beyond the radiographic apex.

Perception of patients with amalgam fillings about toxicity of mercury in dental amalgam.

Objective: The objective of this study is to evaluate the awareness of patients with dental fillings about the toxicity of mercury in dental amalgam.

Materials And Methods: Adult patients having at least one amalgam filling in their mouth were recruited in the Oral Diagnosis Department of OAUTHC, Ile-Ife Dental Hospital. Participants were recruited consecutively as they report in the clinic.

Evaluation of radiographs, clinical signs and symptoms associated with pulp canal obliteration: an aid to treatment decision.

Pulp canal obliteration (PCO) is a sequela of tooth trauma. The dental clinician faced with this condition has to make a difficult decision. The aim of this study was to evaluate the clinical signs and symptoms associated with teeth with PCO and to assess the status of the periapical tissues using the periapical index (PAI) as an aid in making a treatment decision.

Prevalence and causes of fractured permanent incisors in 12-year-old suburban Nigerian schoolchildren.

The aim of the study was to assess the prevalence and causes of traumatic dental injuries to the permanent dentition of 12-year-old school children in Ile-Ife, a suburban population in the south west of Nigeria. A dental trauma cross-sectional survey was carried out through clinical examination of upper and lower permanent incisors and interviews with 415 (212 boys, 203 girls) 12-year-old children attending private and public secondary schools in Ile-Ife, in 2004/2005 by one calibrated examiner. Garcia-Godoy's classification was used.

An analysis of the etiological and predisposing factors related to dentin hypersensitivity.

Aim: To determine the prevalence of different etiological factors of dentin hypersensitivity in patients and to provide information on their association with dentin hypersensitivity.

Methods And Materials: Twenty-nine patients (17 male, 12 female) suffering from pain of dentin hypersensitivity were recruited to participate in the study. A relevant history was taken and dentin hypersensitivity confirmed by using air-blast and tactile stimuli.

Short-term clinical evaluation of four desensitizing agents.

Aim: To evaluate the effectiveness of four topical desensitizing agents in providing short-term relief of dentin hypersensitivity.

Methods And Materials: One hundred sixteen hypersensitive teeth with a positive response to intraoral testing for dentin hypersensitivity were included in this study. The four desensitizing agents tested were Duraphat, 2% fluoride iontophoresis, copal varnish (CV), and Gluma Comfort Bond Plus Desensitizer.

Pulpal sequelae after trauma to anterior teeth among adult Nigerian dental patients.

Background: Epidemiological studies show that about 11.6% to 33.0% of all boys and about 3.

The prevalence of dentine hypersensitivity among adult patients attending a Nigerian teaching hospital.

Purpose: The purpose of this study was to determine the prevalence of dentine hypersensitivity and to examine some associated factors such as initiating stimuli among adult patients attendingthe Dental Clinic of the Obafemi Awolowo University Teaching Hospital, Ile-Ife, Nigeria.

Materials And Methods: All consecutive adult patients that presented at the oral diagnosis unit over a period of 13 months, from March 2003 to March 2004, were included in the study. Relevant history, such as nature of the pain, initiating stimulus, frequency of episode, interference with eating, drinking and toothbrushing were taken.

Failures related to crowns and fixed partial dentures fabricated in a Nigerian dental school.

The purpose of this investigation was to document the failure rate and length of service of crowns and fixed partial dentures (FPDs) fabricated in a Nigerian dental school. The reasons for failure of the initial restorations and their length of service were also ascertained. Also, the numbers of retainers, pontics, and the types of restoration were recorded.

Dental anxiety among patients undergoing various dental treatments in a Nigerian teaching hospital.

The aim of the present study is to evaluate the levels of dental anxiety among patients undergoing various dental treatments and to compare the anxiety levels with those of similar studies conducted with subjects from different socio-cultural backgrounds. Dental anxiety was evaluated by the administration of a questionnaire based on the Corah's Dental Anxiety Scale (DAS). Student t-test and analysis of variance (ANOVA) with Bonferoni correction was employed to compare the mean DAS scores.

The prevalence of dental erosion in Nigerian patients with gastro-oesophageal reflux disease.

BACKGROUND: In various people of the Western world, gastro-oesophageal reflux (GOR) has been reported to be a common problem. Various studies have also assessed the relationship between GOR and dental erosion. The authors are not aware of such studies in Nigerians.

Endodontic flare-ups: comparison of incidence between single and multiple visit procedures in patients attending a Nigerian teaching hospital.

BACKGROUND: Until recently the most accepted technique of doing root canal treatment stresses multiple visit procedure. Most schools also concentrated upon teaching the multi-visit concept. However, it has now been reported that the procedure of single visit treatment is advocated by at least 70% of schools in all geographical areas.
