UP Manila to Represent the Philippines in SEA Dental Student Research Competition

UP Manila to Represent the Philippines in SEA Dental Student Research Competition

MAKATI – Dentistry students from University of the Philippines (UP) Manila placed first and second last July 12 during the International Association for Dental Research – Southeast Asia (IADR-SEA) Dentsply Student Clinician Program (SCP) Country Level Competition.

Ten of twenty-three groups from different dental schools in the Philippines were chosen to compete. Third place was garnered by students from University of the East.
Two teams from UP Manila tied for second place: Nygel Shane Acosta with Effect of Phosphoric Acid Etching on the Shear Bond Strength of a Self-Etch Adhesive, whose fellow researcher was Carol May Llenado and advisers were Dr. Jessica Santos and Dr. Vicente Medina III; and Anne Margaret Cordero and Christeen Lim with Determinants of Dental Service Utilization among Public Elementary School Teachers in a Highly Urbanized City in the Philippines, whose adviser was Dr. Jessica Santos.

First prize was bagged by Beatrice April Alcantara and Priscilla Grace Dimacali with their research entitled Knowledge, Attitudes and Practices of Philippine Basketball Association Players on Mouthguard Use in Preventing Traumatic Dental Injuries. Their fellow researchers for the study were Diana Dela Pasion and Paul Adrian Soriano, and their research adviser was Dr. Arlene Alfaro. The winning group will represent the Philippines in the IADR-SEA/DENTSPLY SIRONA SCP Regional Competition to be held in Taipei, Taiwan this coming August.

TITLE: Knowledge, Attitudes and Practices of Philippine Basketball Association Players of Philippine Cup Season 2016-2017 on Mouthguard Use in Preventing Traumatic Dental Injuries

METHODS:  A cross-sectional descriptive study design utilizing self-administered questionnaires was used to obtain data on the knowledge, attitudes and practices of Philippine Basketball Association (PBA) players on mouthguards as a preventive measure against traumatic dental injuries (TDI). From a total enumeration of a study population of 201 players, 170 respondents (rr=84.6%) were obtained.

RESULTS: Among the players, 91.67% are knowledgeable on mouthguard use in preventing TDI, most commonly because of medical professionals. The most familiar mouthguard was the custom-made type. Only 34.55% of the participants have experienced using mouthguards during their PBA career, most frequently because of advice by a dentist or physician (42.19%) and for protection (43.75%). Reasons for not using are (1) never thought about it (44.04%) and (2) discomfort (43.12%). Among the players, 66.86% have experienced TDI in the PBA. Soft tissue lacerations were the most frequent type of injury, although the sum total of injuries confined to the teeth (n=104 of 113) outnumbered soft tissue lacerations (n=96 of 113). While only 38.41% have a positive attitude towards the PBA requiring mouthguard use, 79.63% have a positive attitude towards educating and promoting mouthguard use among PBA players regardless of history of TDI, preferably by either a dental professional (66.67%) or an athletic trainer (46.51%).

CONCLUSIONS: Almost all PBA players are knowledgeable on mouthguards in preventing TDIs; however, majority have no experience of using mouthguards. Most common reasons for wearing mouthguards are recommendation by a dentist or physician and protection. Most common reasons for not wearing mouthguards are not having thought about it and discomfort. While most of the players do not agree with the PBA requiring mouthguard use, majority are willing to be educated on mouthguard use by a dentist or an athletic trainer.

TITLE: Effect of phosphoric acid etching on the shear bond strength (SBS) of a self-etch adhesive (SEA).

OBJECTIVE: The objective of the study was to compare the shear bond strengths to enamel and dentin of a self-etch adhesive with and without acid etching.

METHODS: 40 bovine mandibular incisors were ground flat to obtain enamel and dentin substrates. A one-step SEA (3M Single Bond Universal Adhesive) was applied with and without preliminary acid atching to both enamel and dentin. The prepared specimens were equally and randomly assigned to 4 groups as follows: group 1 (enamel unetched), group 2 (enamel etched), group 3 (dentin unetched) and group 4 (dentin etched). Composite cylinders (3M Filtek Z250XT) were bonded onto the treated tooth structure. The shear bond strength was evaluated after 24 hours of storage (room temperature) with a testing machine (Shimadzu Autograph AG-X) at a speed of 1 mm/min. The data was analyzed using a one-way ANOVA with a significance level of p<0.05.

RESULTS: Preliminary acid etching resulted in higher mean SBS for both enamel and dentin substrates. The highest mean SBS was obtained from the samples with etched enamel (4.46 ± 1.28) while the lowest mean SBS was obtained from the samples with unetched dentin (3.47 ± 1.95). However, the One-way ANOVA (Table 4.2) analysis came up with a P-value greater than 0.05 (P-value = 0.81).   This means that the higher mean SBS values in the etched enamel and dentin groups were not statistically significant.

CONCLUSION: Preliminary acid etching of enamel and dentin prior to application of a one-step SEA could increase the mean SBS, but the increase is not statistically significant.

ObjectiveThis study aims to determine the factors that affect dental service utilization (DSU) of public elementary school teachers in Manila City, Philippines.

Materials and Methods: Data was collected via personal interviews with the participants.Visit with a private dentist within 12 months prior to the interview served as the dependent variable. Information was gathered on predisposing, enabling, and need factors for DSU based on Andersen and Newman’s Framework of Health Service Utilization. Stata SE version 13 software was used for data analysis. Quantitative variables were expressed as mean and standard deviation, while qualitative analysis as frequency and percentage. Logistic regression analysis was used to determine the factors associated with DSU.

Results: Of the 304 participants, 58.2% (n=177) have visited a private dental provider in the past 12 months. Oral health attitude, person to consult in case of a dental illness, number of contributors to household income, an OFW contributor to the household income, dental insurance, and a regular dental provider were the factors found to significantly affect DSU.

Conclusion: An increase in resources, i.e., additional income contributors, assist in overcoming the financial barrier to obtaining dental care. This study as with others before it has repeatedly associated dental insurance with increased DSU.Having a regular dental provider also significantly affects DSU, highlighting the importance of a dental home. Lack of time is another major barrier to DSU, but time can be set aside for matters perceived to be important enough. The two predisposing factors linked to DSU, Oral Health Attitude (OHA) and Self-medication in Case of Dental Illness, relate to the participant’s regard for oral health.
