    Influence of resilient obturator material on self reported obturator function in individuals with maxillectomies
    (2022) Ikusika O.F., Dosumu O.O., Ajayi D.M. and Sulaiman A.O.
    Removable maxillary obturators are the standard of care in rehabilitating individuals who have had maxillectomies in most specialist healthcare facilities in Nigeria. The rehabilitation of these individuals should emphasise quality of life rather than normative standards by the healthcare professional. This study sought to examine the relationship, if any, between the materials used for obturator fabrication and self- perceived quality of life as reported by the individuals rehabilitated. Materials and methods: Twelve individuals with maxillary defects participated in the trial. They were provided with two definitive obturators each after undergoing post surgical rehabilitation. One of the obturators had a hollow all acrylic bulb while the other had a hollow acrylic bulb with an outer layer of silicone resilient denture liner. The participants wore each prosthesis for a two - week period and crossed over to the other without wash out. The adapted Obturator Functioning Scale questionnaire was administered after the patient had worn each prosthesis. Paired t-test was employed to compare mean obturator functioning scores.

    Impact of tooth loss on the quality of life of patients seen in a Nigerian teaching hospital
    (2016) Ogunrinde, T.J.; Abiodun-Solanke, I.M.F.; Ajayi, D.M.
    Introduction. Tooth loss (edentulism) is an irreversible oral condition that has been described as a final marker of disease burden for oral health. It can impact the quality of life of an individual as it may affect speech and ability to chew properly. Aim of the study. To assess the effect of tooth loss on the quality of life of the Nigerian population using the Oral Health Impact (OHIP) questionnaire, and to determine factors that influence the severity of tooth loss impact. Material and method. A cross-sectional study was performed among partially edentulous patients at a Nigerian teaching Hospital. The Oral Health Impact (OHIP) questionnaire was used to obtain information from the participants. Data collected through the questionnaire were analysed using SPSS version 17 software. Chi square test was used to assess the correlation between the quantity and location of tooth loss and impact of tooth loss on the quality of life. The level of significance was set at P≤0.05. Result. One hundred and sixty five partially edentulous patients participated in the study. There were 80 (48.5%) males and 85 (51.5%) females. The highest mean impact score was 2.27 and was recorded for the question “Have you found it uncomfortable to eat any food because of your missing teeth”? Of the seven domains of OHIP, the highest mean score (4.2) was recorded for the physical pain domain. There was a statistically significant relationship between the location of missing teeth and the severity of impact on the quality of life of the participants. Conclusion. Missing anterior teeth had significant impact on the quality of life of the patients

    The dimensions of oral health–related quality of life (OHRQoL) Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact are the major areas where patients are impacted by oral diseases and dental interventions. The aim of this study was to evaluate whether dental patients’ reasons to visit the dentist fit the 4 OHRQoL dimensions. Dentists (N 5 1580) from 32 countries participated in a web-based survey. For their patients with current oral health problems, dentists were asked whether these problems were related to teeth, mouth, and jaws’ function, pain, appearance, or psychosocial impact or whether they do not fit the aforementioned 4 categories. Dentists were also asked about their patients who intended to prevent future oral health problems. For both patient groups, the proportions of oral health problems falling into the 4 OHRQoL dimensions were calculated. For every 100 dental patients with current oral health problems, 96 had problems related to teeth, mouth, and jaws’ function, pain, appearance, or psychosocial impact. For every 100 dental patients who wanted to prevent future oral health problems, 92 wanted to prevent problems related to these 4 OHRQoL dimensions. Both numbers increased to at least 98 of 100 patients when experts analyzed dentists’ explanations of why some oral health problems would not fit the four dimension. For the remaining 2 of 100 patients, none of the dentis tprovided explanations suggested evidence against the OHRQoL dimensions as the concepts that capture dental patients’ suffering. Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact capture dental patients’ oral health problems worldwide. These 4 OHRQoL dimensions offer a psychometrically sound and practical framework for patient care and research, identifying what is important to dental patients

    To determine the psychometric properties of the General Oral Health Assessment Index (GOHAI) in a sample of adult rural dwellers in Southwestern Nigeria
    (2020) Lawal, F.B
    This cross-sectional study was conducted among 395 adults attending dental outreach programs in Igboora, Nigeria. A translated interviewer administered questionnaire comprising socio demographic characteristics, GOHAI questions, self-rating of oral health and satisfaction with dental appearance was used to obtain data. Oral examination was also performed. The data obtained was analyzed for reliability and validity of GOHAI using SPSS and p value was set at <0.05%. The GOHAI score of respondents ranged from 5 to 60. Many 283 (71.6%) reported at least an impact of oral condition on quality of life (OHRQoL). The most reported impairment was the use of medication to relieve pain (221, 55.9%). GOHAI demonstrated excellent internal consistency with a Cronbach alpha of 0.97. Principal component analysis resulted in extraction of one factor; Kaiser-Meyer-Olkin measure was 0.96 and Bartlett’s test was significant (p<0.001). GOHAI was able to discriminate between those with periodontal treatment needs (p<0.001), missing teeth (p<0.001) or decayed teeth (p=0.001) and those without those oral findings. Higher GOHAI scores (less impact on OHRQoL) correlated negatively with poor selfrating of oral health (rs = -0.72, p<0.001) and dissatisfaction with dental appearance (rs = -0.70, p<0.001). More males (p=0.012) and divorced respondents (p=0.016) reported impacts on OHRQoL than others. GOHAI has acceptable psychometric properties and validity among underserved adults living in a rural Nigerian community

    Applicability and cross-cultural adaptation of the self-administered Child–OIDP in a rural Nigeria community
    (2017) Lawal, F.B.; Dauda, M.A
    The utilization of the Child Oral Impact on Daily Performances (Child–OIDP), one of the most widely used quality of life measures for children, in rural communities will require cross adaptation of the measure since rural communities in Africa are in no small way influenced by the prevailing cultural norms and values. The aim of this study was to assess the applicability of self administered Child–OIDP measure in a rural Community in Nigeria. A cross sectional study was conducted among 403 secondary school students in Igboora, Nigeria using self-administered Child–OIDP questionnaire translated into the local language. The mean age of the study participants was 12.4 (±0.7) years. The impact of oral health on their daily performances scores ranged from 0 to 66. Higher OIDP scores were significantly associated with perceived need for dental treatment (p < 0.001), satisfaction ratings of oral health condition (p = 0.001), satisfaction ratings of tooth appearance (p = 0.030) and pain (p < 0.001). The use of frequency or severity scales separately or combined exhibited similar and acceptable validity and reliability; however, the frequency scale alone had the highest Cronbach’s alpha value (0.876), while use of both frequency and severity scales was best for inter–item correlations (0.552-0.714). The translated version of the Child–OIDP measure is a valid and applicable tool in a rural community. Use of either the frequency or severity scale of this version of Child–OIDP is valid, cross-culturally adaptable and recommended

    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. The purpose of this paper was to review dentine hypersensitivity in view of causes, diagnosis and management. Articles used were found by searching the keywords: dentine hypersensitivity, tooth wear lesions, desensitization, gingival recession, treatment of hypersensitivity. 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. 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

    Impact of Oral Health on The Quality of Life of Elementary School Teachers
    (2015) Lawal, F.B,; Taiwo, J.O; Oke, G.A
    The success of preventive school health programs is largely dependent on teachers who are role models to pupils and pivotal to implementation. It is therefore important to understand the perception of school teachers about the impact of oral health on their daily activities. The aim of this study was to assess oral health related quality of life of elementary school teachers by evaluating the impact of oral conditions like dental caries and periodontal disease on their daily performances and school work. This was a descriptive cross sectional study in which 407 teachers were selected through multistage random sampling technique. Data were collected with structured interviewer-administered Oral Impact on Daily Performances (OIDP) questionnaires and by clinical oral examinations. Data were collated and analyzed with SPSS. The prevalence of reporting of impacts on daily performances was 39.1% with eating and enjoying food being the most commonly impacted activity. Impacts on daily performances were more likely to be reported by teachers with better education (p = 0.019). Teachers with caries had higher odds of reporting impacts as a result of oral health status (CI: 1.04, 5.64, p = 0.040). The severity of periodontal disease found on clinical examination was not related to reporting of impacts on quality of life (p > 0.05). The oral health status of school teachers impacted significantly on their daily performance and school work when they experienced pain. Painless but highly prevalent oral lesions were, however, not perceived to influence their quality of life
