Activated Charcoal-based Dental Products: Awareness, Knowledge and Opinion of Dental Practitioners in a Tertiary Hospital in Nigeria.

BACKGROUND: Recently, there is a resurgence in the practice of oral hygiene with charcoal-based oral hygiene products such as charcoal based dentifrices, toothbrushes and mouthwashes. Dental professionals need to be aware of these products to rightly educate patients on acclaimed merits and demerits. OBJECTIVE: To elicit the awareness, knowledge and opinion of dental professionals on the use of activated charcoal oral health products. METHODS: A cross-sectional study carried out among dental professionals. Data was collected using a pretested, self-administered questionnaire that sought information on respondents' demography, their awareness, knowledge and opinion on charcoal-based oral health care products. Descriptive and comparative analyses were done using SPSS version 21.0. and statistical significance were set at p <0.05. RESULTS: One hundred and three dental professionals participated with a slight female predominance and a F:M of 1,1:1. Forty-six (44.7%) and 10 (9.7%) respondents respectively were aware of charcoal-based toothpaste and toothbrush (p= 0.02, p=0.04). Sixteen (15.5%) of those who were aware got information from friends/colleagues. Only 19 (54.3%) of dentists knew that charcoal-based toothpaste can be used in tooth whitening and in the prevention of dental caries and periodontal diseases (p=0.01). There was generally a low knowledge about the uses, side effects and sequalae of the use of charcoal toothpastes and toothbrushes among all dental professionals. Attitude to use and willingness to recommend these products was also poor among them. CONCLUSION: There was a low awareness and knowledge of the uses and sequalae of charcoal-based oral health products among dental professionals.

Bad-breath: Perceptions and misconceptions of Nigerian adults.

OBJECTIVE: To provide baseline data about bad-breath perception and misconceptions among Nigerian adults. METHODS: Multi-center cross-sectional study of individuals aged 18-64 years using examiner-administered questionnaires. Age comparisons were based on the model of emerging adults versus full adults. Data were recoded for statistical analyses and univariate and secondary log-linear statistics applied. RESULTS: Participants had lopsided perceptions about bad-breath. While 730 (90.8%) identified the dentist as the expert on halitosis and 719 (89.4%) knew that bad-breath is not contagious, only 4.4% and 2.5% associated bad-breath with tooth decay and gum disease respectively. There were no significant sex differences but the older adults showed better knowledge in a few instances. Most respondents (747, 92.9%) would tell a spouse about their bad-breath and 683 (85%) would tell a friend. CONCLUSIONS: Participants had lop-sided knowledge and perceptions about bad-breath. Most Nigerian adults are their "brothers' keepers" who would tell a spouse or friend about their halitosis so they could seek treatment.

Association between periodontal disease and pregnancy outcomes.

OBJECTIVE: To evaluate the association between periodontal disease and pregnancy outcomes like preterm birth and low birth weight. PATIENTS AND METHOD: Interviewer-administered questionnaires were completed by the subjects who attended the antenatal clinic of the Lagos University Teaching Hospital, Lagos. Information obtained included; maternal age, gestational age, marital status, educational status, occupation and expected date of delivery. After delivery, the questionnaire was completed with baby's weight at birth and the actual date of delivery. Clinical assessment of the periodontium was done using Oral Hygiene Index (OHI) and Community Periodontal Index of Treatment Needs (CPITN). Participants were divided into three groups: Test, Control I and Control II groups. Scaling and polishing were done for all patients with periodontal disease before (Test group) and after delivery (Control I). All Control II participants (those without periodontal disease) were given Oral hygiene instructions. Descriptive and comparative analyses were done using Epi info version 2008. RESULTS: Four hundred and fifty women received the questionnaire but the response rate was 94%, giving an actual sample size of 423 participants. Maternal age range was between 18 and 34 years with mean age of 29.67 (± 3.37). Gestational age at the point of recruitment was between 10 weeks and 26 weeks with mean of 23.34 (± 4.05). The prevalence of periodontal disease among the study group was 33.38%. About 71% of the participants attained tertiary level of education; only 0.7% had no formal education. There was 9.9% use of alcohol among the participants. The mean oral hygiene score for the participants was 1.94 (± 1.31). The prevalences for preterm deliveries, low birth weight and spontaneous abortion were 12.5%, 12.1% and 1.42% respectively. CONCLUSION: This study confirms periodontal disease as a probable risk for adverse pregnancy outcomes such as preterm delivery and low birth weight. Therefore, health workers should be encouraged to promote good oral health among women.

Partial edentulism and unmet prosthetic needs amongst young adult Nigeria.

INTRODUCTION: Treatment options for missing tooth/teeth which are mostly commonly caused dental caries, periodontitis and trauma include partial dentures, bridge and implant. In developing countries, missing tooth/teeth replacement constitutes a high unmet dental need. The objective of the study was to determine the prevalence of partial edentulism and prosthetic unmet dental needs among young adults in Nigeria. MATERIALS AND METHODS: A total of 244 medical students of college of medicine were recruited and studied using interviewer administered questionnaire which elicited information on sociodemographic, tooth loss and replacement. Data was analyzed with SPSS version 16.0 statistical software for windows. RESULTS: There were 98 males (40.2%) and 146 females (59.8%). A total of 35 participants out of the 244 studied participants had missing tooth/teeth giving a prevalence of 14.3%. The major reason of tooth loss was caries (48.6%). The upper left (16.7%) and right (16.7%) had the highest tooth mortality. Of the 35 participants with missing teeth, 4 (11.4%) of had replacement while 31 (88.6%) did not have any form of replacement. The teeth replaced were upper right, left anterior (75%) and upper right posterior (25%). Reasons for non-replacement were not being bothered--14 (45.2%), ignorance of replacement therapy-- 7 (22.6%), misinformation--1 (3.2%) and lack of money--2 (6.5%). Those that replaced 4/42 (9.5%) did so with removable partial dentures (100%). The majority that replaced were females 3/4 (75%). Half (50%) of those that replaced were satisfied and the reasons for non-satisfaction were pain from denture and unnatural feel of denture. CONCLUSION: Data from this study revealed low prevalence of tooth loss with high unmet tooth replacement needs among the participants. Tooth/teeth replacement options should be incorporated in postoperative instructions after extraction and dental awareness should be improved among medical students.

Periodontitis & sub-fertility; opinions and practices of Nigerian specialists.

BACKGROUND: Increasing evidence in the emerging field of periodontal medicine continues to stimulate research to verify the association between chronic periodontitis and general health. The link between chronic periodontitis and sub-fertility has not been well-investigated except for a handful of reports spanned over several decades. METHODS: As a prelude to a series of observational and interventional studies, 119 specialists and doctors participated in an online survey to ascertain their practices and opinions about this link. Our main exposure variables were dental history taking, periodontal/dental referrals and knowledge of possible link between chronic periodontitis and sub-fertility. RESULTS/FINDINGS: Our findings showed that dental history taking and periodontal/dental referrals were not part of sub-fertility management protocols of Nigerian specialists and doctors. These findings proved true irrespective of basic and postgraduate experience. Specialty was the only explanatory variable that accounted for statistical significance with the main exposure variables but the figures of members of different specialties were too low for any meaningful comparisons. CONCLUSIONS: The findings confirmed our suspicion of an almost complete lack of knowledge of this unlikely yet plausible association which deserves further research.
