Are there associations between the occurrence of dental fluorosis and the experience of dentine hypersensitivity? A cross-sectional study.

Objectives: Associations between the occurrence of dentine hypersensitivity (DH) and dental fluorosis (DF) have been suggested. Testing this association requires studies among populations with both conditions. This study aimed to determine the association between DF and the experience of DH among a population endemic for DF. Methods: This was a cross-sectional study conducted in 2021 over 6 months among 428 adult patients. Participants' demographics were collected, followed by verbal screening for DH and oral examinations. Clinical assessment for DH was carried out by tactile and evaporative methods. The presence and severity of DF were also assessed using the Thylstrup and Fejerskov Index. Data analysis included Chi-square and correlation statistics to assess the presence and strength of associations. Results: The overall prevalence of DH was 31.1%. A higher proportion (41.1%, P < 0.001) of participants with DF had DH than those without DF. The association between DH and DF was minimal but statistically significant (r = 0.174, P < 0.001). Among those with DF, the prevalence of DH was highest in participants with severe fluorosis (50%, P = 0.740). The proportion of sensitive teeth to the teeth examined was significantly higher (P < 0.0001) for participants with DF (289/4167, 6.9%) than participants without DF (267/6758, 4%). This proportion was also highest for severe DF (20/254, 7.9%, P = 0.572) than the mild and moderate forms. Conclusion: DH was more prevalent among individuals with DF. The prevalence of DH was not dependent on the severity of DF.

Access to root canal treatment in a Nigerian sub-population: assessment of the effect of dental health insurance.

BACKGROUND: The final pathway of tooth mortality lies between tooth extraction, and the more expensive and less accessible root canal treatment (RCT). AIM: To determine the extent to which individuals' financial resources as measured by socioeconomic status and dental insurance coverage affects their access to RCT. METHODS: A hospital-based study that used a 15-item questionnaire to collect data among patients scheduled for RCT. All scheduled subjects (N = 291) over a one-year period constituted the sample for the study. Using the SPSS software, associations between the subjects' variables, and the dental insurance status were carried out with Chi square and independent t test respectively at 95% confidence interval. RESULTS: Two hundred and ninety-one subjects were to have 353 RCTs within the study period. A high proportion (79.7%, p < 0.001) of the subjects had dental health insurance, majority (95.3%) of which was government funded. 20.9% of those with previous tooth loss was due to inability to afford cost of RCT. The lowest socioeconomic group had the highest proportion (90%, p = 0.421) of insured that visited for RCT. CONCLUSION: Dental insurance increased access to RCT. Socioeconomic status did not affect dental insurance status and dental visit for RCT.

Workplace assault and its' impact to service delivery amongst dental professionals at Tertiary Hospitals in Northern Nigeria

Objective: The growing global public health concern of workplace assaults has necessitated that workers' health and safety be given same priority as patient's safety. The study assessed the prevalence of workplace assault and its' impact on service delivery among dental professionals at tertiary hospitals in Northern Nigeria. Methods: A cross-sectional survey of 60 dental professionals working in tertiary hospitals actively involved in undergraduate and postgraduate trainings for dental workforce in Northern Nigeria. Multi-stage sampling technique was used in selection of respondents and participation was voluntary. Data was collected using structured self-administered questionnaire. Statistical analysis was done using SPSS version 23.0 and p-value ≤ 0.05 was considered statistically significant. Ethical approval was received. Results: Sixty percent dentists and 40.0% dental auxiliaries participated in the study. Assault prevalence was 38.3% observed more among dental professionals (44.0%) in their first year in practice. Types of assaults experienced were; non-physical 19 (82.6%) with loud shouting and threats as most frequent, physical 3 (13.0%) with bullying and mobbing most frequent, and combination was 1 (4.4%). Patients (60.9%) and relatives (52.2%) were major culprits, and long appointment (65.2%) and treatment cost (60.9%) were main reasons for assault. Respondents (39.1%) expressed impact on their productivity and 69.6% respondents were ill-prepared to handle it. Conclusion: The prevalence of workplace assaults on dental professionals was fairly high and those in their first year in practice suffer more assault than others. Assault preventive programs should however specifically target this group in consideration with the unique nature and varied needs of each healthcare institutions

Beyond the Relief of Pain: Dentin Hypersensitivity and Oral Health-Related Quality of Life.

Pain is a constant symptom of dentin hypersensitivity (DH), which is a common condition that affects daily life and negatively affects the quality of life (QoL). Diagnosis and outcome measurements following the treatment of the disease require accurate pain assessment. The definition of pain underlies the complexity of its measurement as different factors modulate daily experience. The reproducibility of the prescribed stimuli for inducing DH pain clinically is difficult to achieve. This pain mevaasurement is made with unidimensional scales that are inadequate to capture the other dimensions of pain. The only specific QoL tool available for DH still requires testing in other populations and cultures. This article reviews the appropriateness of the current methods of DH pain assessment and the tools that consider the other pain dimensions. It also looks at its impact on the oral health-related quality of life (OHRQoL) of people with DH. The findings will create interest and facilitate research in this field of DH pain measurement and management.
