Restorative Dental Care and CO V ID -19 Pandemic: Reviewing the Treatment Guidelines and Evaluating Patients' Opinion Qualitatively in a Nigerian Tertiary Hospital.
(2020) Ajayi, D.M.,; Ogunrinde,T.J.; Gbadebo, S.O.,; Sulaiman, A.O.; Ogundare, T.
Objectives: The study aimed at reviewing the different measures and strategies put in place globally to ensure successful management of restorative dental patients during the COVID-19 era and to evaluate the knowledge and information on patients' opinion on the impact of the pandemic on their restorative care through a qualitative study design. Methodology: Search for articles on guidelines for restorative care through PUBMED using the keywords COVID-19, guidelines, protocols and restorative care was done. About 42 related articles were downloaded and appraised for necessary information as regards standard protocols in restorative care. The qualitative study involved individual interview of randomly selected 15 patients seeking restorative care that consented to participate in the study. The audiotaped interviews were transcribed verbatim and thematic analysis of data generated was done. Four themes were identified from the data and these included knowledge about COVID-19, view about the infection and infection control, the effects of the lockdown on treatment as well as the fear about contracting the disease. Result: Standard guidelines for different phases (pre, intra and post treatment) were carefully outlined. Fifteen patients, 8 females and 7 males between ages 19 and 72 years with mean age of 39.6 ±17.53 years were interviewed. All the patients had knowledge about COVID-19 infection but the majority were not familiar with the relationship between dentistry and spread of the infection. Repeated visits to dental clinic without being attended to, during the lockdown resulted in patients using self-medication. The fear of contracting the infection in dental clinic was low among the participants and the few that had the fear were those that showed good knowledge about the risk of contracting COVID-19 infection through restorative care. Conclusion: Strict adherence to standard protocols and guidelines should always be followed even after COVID-19 pandemic to ensure continual confidence of patients in the clinicians.
The influence of the design of mandibular major connectors on gingival health
(2014) Ogunrinde,T.J.; Dosumu, O.O.; Shaba,O.P.; Akeredolu, P.A.; Ajayi, D.M.
Background: The objective of this study was to assess the influence of lingual bar and lingual plate major connectors on plaque retention and gingival health among patients who presented in University College Hospital (UCH), Ibadan, Nigeria. Methods: This comparative intervention study was carried out among fifteen patients aged 28 to 60 years with Kennedy class III lower edentulous arch. Two metal dentures with different major connector designs (lingual plate and lingual bar) were fabricated for each patient. After professional scaling and polishing, a baseline score of the oral hygiene was done using the plaque index of Sillness and Loe and the gingival health using the gingival index of Loe and Sillness. Each patient was randomly assigned either a denture with the plate or bar design to use for three months and then recalled for reassessment of oral hygiene and gingival health. Professional scaling and polishing was done post removal and a new baseline assessment of oral hygiene and gingival health recorded. The dentures were now exchanged and the second major connector design inserted. Each patient was recalled for reassessment of the oral hygiene and gingival health after three months. The level of plaque accumulation and gingival inflammation with the use of lingual plate and bar dentures were determined and compared. Results: There was no statistically significant difference in the mean plaque index score for the lingual bar design at three months and the mean plaque index score at three months for the lingual plate (p>0.05). However, a statistically significant lower mean gingival index score was noted three months post insertion for lingual bar designs when compared to plate designs. Conclusion: Within the limitation of this study, better gingival health was noted with the bar designs when compared with the plate designs.
Causes and pattern of fracture of acrylic dentures among patients seen in a Nigerian teaching hospital
(2007) Ogunrinde,T.J.; Ajayi, D.M.; Dosunmu, O.O
There is little information on the causes and pattern o f fracture of acrylic dentures in Nigerian patients despite being the most frequently employed design in Nigeria. The aim of this study was to determine the average life span o f acrylic dentures before fracture, the causes and pattern of fracture o f acrylic dentures in a Nigerian population. A ll consecutive patients that presented with fractured acrylic dentures at the Dental Centre, University College Hospital, Ibadan between January and July 2006 and were willing to participate were recruited into the study. A structured interviewer-administered questionnaire was used to record data from the patients. The questionnaire focused on patients’ demographic data, age of acrylic denture as at the time of fracture, causes and pattern o f fractures. The data were analysed using SPSS Version 11. A total of sixty-two patients were included in the study. They presented with sixty-nine fractured dentures. Five were complete dentures while 64 were partial dentures. The average life span was 7.4years ± 6.6 (SD) years. Early fracture was seen in 9 (13.4%), intermediate fracture in 29 (42%), and late fracture in 3 1 (44.9%) cases. The commonest cause o f fracture was mastication as seen in 30.4% of the cases while the least cause was fight (4.3%). The commonest site of fracture (34.8%) was the palatal plate around the crest o f the edentulous ridge while fracture of wrought metal clasps was the least, occurring in 1.4% o f cases'. We recommend proper design with balanced articulation and more emphasis on compliance to post insertion instructions by patients to prevent early fracture of acrylic dentures. Also, reinforcing the acrylic denture base especially in stress bearing area may prolong the life span of these prostheses.
