Asian Journal of Dental Sciences, Page 1-11

Aims: To evaluate the academic stress and oral hygiene practices among students in health-related profession such as medicine and surgery, nursing, dentistry and pharmacy

Study design: This study was a cross sectional survey done among students in health-related professions

Place and duration of study: Faculties of Medicine and Surgery, Dentistry, Pharmacy and Nursing in College of Health Sciences, University of Port Harcourt between August and September, 2021.

Methodology: Four hundred and twenty-two participants in health-related professions (dentistry, pharmacy, medicine and surgery and nursing) in the penultimate and final year who gave their consents were recruited for the study (266 females, 156 males; age range= 17-37 years). Self-administered questionnaires were used to collect data on demographics, perception of course stress and oral hygiene practices. Data was analyzed using IBM SPSS (statistical package for the social sciences) version 25.

Results: Sample size was 422 and response rate was 100%. P value was set at <0.05.

About two-third of participants reported a high academic stress and said they spend between 9 and 15 hours daily on academic work (p=0.02).  Majority of the respondents cleaned their teeth with toothbrush and fluoridated toothpaste. 56.4% of the participants brush twice daily, 49.3% change their toothbrush every 3 months and 18.7% change their toothbrush when it lost its efficiency. 84.8% of the respondents were aware of interdental

Conclusion: The oral hygiene practice among the undergraduates was fair despite their high academic demands. There is however, still the need to motivate them for improved oral hygiene practice.

Implant supported prothesis are used in rehabilitation of cases with sever resorption of alveolar bone. However, the limitations due to the close proximity between critical anatomical structures (as maxillary sinus, inferior alveolar nerve)  and crest of the ridge sometimes lead to difficulties in implant placement. All on four technique was developed by placing four implants in the anterior maxilla or mandible, the two most distal implants was angulated to overcome bony deficiencies or anatomical structures and maximizing the available bone used without grafting. Biomechanical studies showed that the implants excess loading is the significant factor cause bone resorption. The goal of the Study was to evaluate the stress distribution of fixed implant-supported prostheses using “all-on-four” concept for the treatment of mandibular completely edentulous ridge “in vitro study”.

Materials and Methods: The finite element model components as the overdenture, mucosa, implants, angled base, abutment, cortical and cancellous bones were created in "Autodesk Inventor. The model was subjected to Six loading conditions of 100N, 50N vertically and oblique (antroposterior) at central incisors respectively. In addition to 200N and 100N unilaterally vertically and oblique (buccolingual) at molar region respectively, 200N and 100N bilaterally vertically and oblique (antroposterior) at molar regions respectively were investigated.

Results: All values of deformations and stresses appeared on the all model components were within physiological limits under all cases of load application.

Conclusion: tilted implants at molar area did not affect the system behavior (did not show beak of stresses or deformation).

Asian Journal of Dental Sciences, Page 23-31

Objective: The purpose of the study was to explore the experiences of parents and carers of adolescents with disabilities and learning difficulties in terms of their dental problems and their access to dental care. The study focused on exploring parents daily experiences when seeking dental care. The ultimate objective of the study was to identify ways to improve the quality of dental care for adolescents with disabilities and learning difficulties.

Methods: A qualitative study was conducted through twenty semi-structured interviews with parents of adolescents with disabilities and learning difficulties. The method of thematic analysis was employed by the researchers towards the analysis of the qualitative data collected from the interviews.

Results: The following themes emerged during the thematic analysis: 1) parents’ experiences from the shock of their child’s first diagnosis towards the process of acceptance of their child’s disability or learning difficulty. 2) Erosion of family cohesion. 3) High demands of parents’ daily life. 4) Bureaucracy. 5) Financial challenges and unfulfilled health needs.    6) Organizational weaknesses. 7) Underestimation of dental care needs. 8) Search for quality therapeutic relationships. 9) Emotional distress from stigma and bulling. 10) Need for an individualized approach depending on the type and severity of the disability and learning difficulty. 11) Anxiety about the future including the need for social protection. 12) Encouragement of children's progress.

Conclusions: Many challenges have emerged during the study towards parents’ search for quality primary and secondary dental care for their children. Some of these challenges include but are not limited to the lack of provision of information, barriers inaccessibility, long waiting lists, high private expenses, etc.
