Fistula in cleft lip and palate patients (2018)

Introduction: The cleft lip and palate congenital malformation is a common condition, which poses a large burden of care on the young patients and their caregivers. The World Health Organization reported the prevalence of cleft lip with or without cleft palate to be 10 in 10,000 births in the United States and worldwide and 12 in 10,000 births in Canada (IPDTOC, 2011). Post-operative palatal fistula is frequently encountered after the surgical repair of a cleft lip and palate deformity. A wide range of fistula occurrence rates, have been reported in the literature with significant variability. After conducting a systematic scoping review of the cleft palate literature we found that high quality studies were needed in this field. Additionally there were very few Canadian studies available on this subject. We recognized the need to investigate the incidence of palatal fistula at British Columbia’s Children’s Hospital (BCCH) to be able to compare our rates with other centers worldwide. As a result of our research, we realized a gap in the literature, which was the lack of a standardized assessment protocol for the follow up of cleft lip and palate patients.Methods: A retrospective chart review was performed at British Columbia’s Children’s Hospital to examine the incidence of palatal fistula in children with non-syndromic clefts and to identify determinants associated with higher fistula rates.In preparation for the protocol development we conducted electronic database searches and contacted 13 major cleft centers worldwide.Conclusion: The systematic review concluded that the research mainly focused on surgeries and fistula-related risk determinants. The level of evidence was low and the quality was poor. No consistent pattern was detected between fistula occurrence and any of the studied risk determinants. The medical chart audit determined that almost a quarter of patients at BCCH presented with a palatal fistula. The significant risk determinants were severity of the cleft, less experienced surgeons, and the time period in which surgeries were performed. The structured protocol was developed and it will help facilitate data collection of cleft patients prospectively and prevent deficiencies in current medical reporting.

A retrospective review of implant treatment outcomes placed between 2009 and 2018 by the graduate periodontics residents at the University of British Columbia, Dental Clinic (2020)

Objectives: This study was conducted to examine the rates and potentialpredictors of implant failures and peri-implant condition associated withtreatments provided by the periodontal residents at the graduate dental clinic atthe University of British Columbia (UBC).Materials and methods: A retrospective review of information from dentalcharts of patients who received dental implants at the UBC graduate clinic betweenJanuary 1st, 2009, and December 31st, 2018, by the graduate periodontics residents.Results: During the review period, 597 patients received a total of 1494 dentalimplants. The majority of potential risk indicators we examined did not havestatistically significant associations with either implant failures or peri-implantcondition.Conclusion: The implant failure rate was lower than the failure rate reported in aprevious retrospective study done in the same university setting. To ensure theproper documentation of all cases, the standardized protocol for informationrecording, including follow-ups, should be implemented.

A retrospective study of the population served by the Children’s Dental Program at the University of British Columbia Faculty of Dentistry (2020)

Objective: Many dental schools contribute to public health through free or reduced-fee treatment for underserved pediatric populations. Since the 1970s, the University of British Columbia (UBC) Faculty of Dentistry’s students provide dental treatment to pediatric patients through a bussing program known as the Children’s Dental Program (CDP), which transports children from areas outside of Vancouver city limits to UBC for free care. The purpose of this study was to quantify the scope of the CDP by reviewing the populations served and the dental treatment provided using digital records of the past twenty-one years. Methods: De-identified data was retrieved from UBC’s axiUm Dental Software database, including demographic information and treatment procedures performed. The twenty-one years were divided into 4 time periods (Period 1 to Period 4). The first three digits of the patients’ postal codes (i.e. their forward sortation area) were used to create choropleth maps using QGIS Software. The treatment procedures were organized into ten categories (including diagnostic, preventive, restorative, and oral surgery), and their proportions and means were calculated. A Standardized Treatment Provision Index (STPI) was also created to facilitate more detailed comparisons. Using SPSS Software, statistical analysis was done at three levels: procedure-, patient-, and student-level.Results: A total of 5,203 patients were treated between April 1997 and March 2018. Their mean age was 7.8 years. A majority were from the Vancouver suburbs of Surrey, Abbotsford, and Burnaby. Over each successive period, the mean number of procedures per patient decreased. All levels of analyses also revealed decreases in restorative and preventive procedures from Periods 1 to 4.Conclusions: The CDP has been providing dental care to children from many disadvantaged communities located in the Vancouver suburbs, with dental students gaining valuable experience working with pediatric patients. The decrease in restorative procedures may be due to decreases in the children’s caries experience. The program should advocate for more preventive procedures such as fluoride applications and fissure sealants. Last but not least, the Standardized Treatment Provision Index (STPI) has great potential in epidemiology as a measure of treatment provision in a population and as a proxy of its treatment needs.

Self-esteem, self-perception of malocclusion, and motivation to seek orthodontic treatment (2020)

Objectives: The study examined whether a relationship exists between self-esteem, self-perception of malocclusion and motivation to seek orthodontic treatment. Methods: 49 patients were recruited from the Graduate Orthodontics Department, Faculty of Dentistry, UBC. An online survey inquired about their self-esteem, motivation to seek orthodontic treatment, and self-perceived esthetics of their malocclusion. The objective severity of malocclusion was assessed by a single examiner. Subjectively and objectively measured malocclusion were compared and subsequently related to patient self-esteem and their motivation to seek orthodontic treatment. Self-esteem was measured by the Rosenberg Self-Esteem Scale; self-perception of malocclusion through the aesthetic component of the Index of Orthodontic Treatment need (IOTN-AC); and the objective malocclusion severity by the IOTN-AC, IOTN-DHC (Dental Health Component) and by the Index of Complexity and Orthodontic Need (ICON). Patients indicated their motivation for treatment on a scale 1-100%. Results: Self-esteem and motivation to seek orthodontic treatment did not differ significantly with age, gender, objectively assessed severity or malocclusion, or self-perceived severity of malocclusion. Self-esteem was not significantly different among participants with different motivations to seek orthodontic treatment. Objective measures of malocclusion (IOTN-AC, ICON, IOTN-DHC) were significantly associated. Higher and lower self-esteem were not significantly related to an underestimation, or overestimation of self- perceived malocclusion severity (self-perception discrepancy). Motivation to seek treatment was significantly higher in participants with severe, as compared to mild treatment need when the severity of malocclusion was measured objectively using the ICON scale. Self-esteem was not significantly related to motivation to seek treatment when compared among objectively assessed malocclusion groups, self-perception groups, or self-perception discrepancy groups. Conclusions: Self-esteem was not related to objectively measured severity of malocclusion, self-perception of malocclusion, or the discrepancy between self-perception and objectively determined malocclusion severity. Motivation to seek treatment was not related to self-esteem or self-perception of the severity of the malocclusion but was related to the objectively measured malocclusion severity.

Space maintenance treatment planning for pediatric patients (2020)

Objective: The current study examined differences in treatment planning for space maintenance between pediatric dentists and general dentists.Methods: Two online self-administered electronic questionnaires were developed and administered by the UBC Qualtrics Survey software. One was a 32-question questionnaire that was administered to 1640 general dentists, and the other was a 31-question questionnaire that was administered to 41 pediatric dentists registered with the College of Dental Surgeons of British Columbia, Canada. The questionnaires consisted of three clinical case scenarios regarding space management in pediatric patients. The assessments on space maintenance treatment planning were based on the following cases: 1. Extraction of tooth #7.4 in primary dentition; 2. Extraction of tooth #7.5 in primary dentition; and 3. Premature loss of tooth #7.3 in mixed dentition. The survey also acquired information about the practitioners` demographics and their knowledge, attitudes, and practices towards space maintenance for each specific case. Statistical analysis was conducted using the independent sample t-test, Mann Whitney U test, Chi-square test, and Fischer’s exact test. Results: The response rate for general dentists was 20.3% (n=320), and for the pediatric dentists it was 56.1% (n=23). The majority of general dentists (76.7%, n=244), and all pediatric dentists (100%, n=23) chose to place a band and loop appliance after extraction of tooth #7.4. The majority in both groups selected to place a distal shoe appliance after extraction of tooth #7.5 (59.2%, n=189 of general dentists and 78.3%, n=18 of pediatric dentists), and both general (59.6%, n= 189) and pediatric (69.6%, n=16) dentists selected that they would consider an orthodontic consultation for the case about the premature loss of tooth #7.3. Differences in attitudes about their dental school/residency training were the strongest determinant associated with treatment planning. There were no statistically significant differences in mean total knowledge scores between the pediatric and general dentists. Conclusions: Space maintenance treatment planning is multifactorial; however, differences in attitudes towards the practitioners’ training strongly associated with their decision making.

Authoritative parenting model for improving oral self-care skills in orthodontic patients (2019)

Objectives: This blinded randomized controlled clinical trial assessed the effectiveness of an authoritative parenting model in improving the oral hygiene skill level of adolescent orthodontic patients. Methods: The sample consisted of patients aged 10-16 years undergoing orthodontic treatment at the UBC’s graduate orthodontic clinic. Patients were randomized into two study groups: an intervention group receiving oral health promotion material and a template of a parent-child contract, and a control group that received conventional dental instructions provided by orthodontic graduate students. Oral hygiene skill levels were assessed by measuring percentage of total plaque (after best brushing) at three observation periods (baseline, 1-3-month follow-up, and 3-7-month follow-up). Plaque scores were calculated from the photographs of teeth with disclosed plaque, employing the manual for the standardized digital estimation of dental plaque scores. Results: Overall, patients had high plaque scores with large within-group variations indicating deficiency in oral self-care skills (OSCS). Although skills improved from the baseline in both study groups, there was no statistically significant difference (p>0.05) between the intervention group and the control group. The parental compliance rate with the intervention was low (~30%); however, within the compliant group, there was a non-significant trend for OSCS improvement. The baseline plaque level was the only significant predictor of future OSCS. Conclusions: The authoritative parenting model did not result in greater improvements of OSCS of orthodontic patients in comparison to the conventional dental instruction. Parental compliance with the intervention was low; therefore, it is important to identify reasons for non-compliance.

Waiting room time : an opportunity for caregiver oral health education (2018)

The UBC Children’s Dental Program (CDP) has provided free basic dental treatment for high caries risk children, from marginalized populations, since the mid-1970s. Children are referred to the program by Health Authority Staff in metro Vancouver. Treatment is provided by senior dental students under the supervision of UBC Pediatric Dentistry instructors. However, the students have limited time to provide health education to the accompanying caregivers. Therefore, this project developed a ʺwaiting-room basedʺ dental health education program (DHEP) to engage the caregivers of participating children. Our main objectives were to assess the feasibility and acceptability of the DHEP and its short term effectiveness in changing parental dental health related behaviours.A situational analysis using structured interviews was performed with the caregivers and other stakeholders of the CDP: Health Authority Staff, UBC Pediatric Dentistry instructors and participating dental students. After the assessment of caregivers’ dental knowledge, dental behaviours, attitudes as well as preferences about a dental educational program, the DHEP was developed and implemented in the waiting rooms at UBC’s two children’s dental clinics. Follow-up phone calls with the caregivers assessed their short term self-reports of changes in dental health related behaviours. Comparisons before and after being exposed to our DHEP were made using Chi-square tests; significance was set at P

The oral health-related lifestyle of Vancouver inner-city elementary school-aged children (2013)

Objectives: To describe the oral health-related lifestyle of Vancouver inner city elementary school-aged children and relate different aspects of their oral health-related lifestyle with demographic and socioeconomic factors. Methods: This cross-sectional study used a structured questionnaire with some open-ended items to survey 424 school-aged children in Vancouver inner city elementary schools (53.3% boys and 46.7% girls). There were two versions of the questionnaire: the shortened version was used for grades 1-3 and included only multiple choice questions while the comprehensive version for grade 4-7 comprised both structured and open-ended questions. In the questionnaire, different items were used such as ordinal, interval and qualitative to acquire information about different aspects of oral health-related knowledge, attitudes and behaviours. Results: Overall, there was a deficiency in oral-health related knowledge and corresponding behaviours in all age groups and both genders. Thus awareness about oral health in this cohort of children needs to be improved. The oral health-related lifestyle did not differ between boys and girls except for the interdental cleaning behaviour (P=0.033). Oral health-related lifestyle did not differ according to socio-demographic characteristics except for the difference in consumption of sugar-containing drinks among age groups (P

Dental health needs and related factors in inner-city Vancouver elementary school aged children (2013)

Objectives: The aims of the study were: to describe the dental health and treatment needs of inner-city Vancouver elementary-school-aged children and to examine differences in dental health between socioeconomic and ethnic groups. Methods: Principals of all 10 elementary schools in inner-city Vancouver were approached. Principals of 7/10 inner-city Vancouver elementary agreed to have their schools participate in this project. Consent letters were sent to parents/guardians. The clinical data included assessment of dental health and treatment needs. Self-reported data comprised information about ethnicity, gender, place of birth, years lived in Canada, dental insurance, family education and income. Results: A total of 561 children of age 5-12 year were examined (kindergarten and grades 1-7). Of the children from ethnic minorities, 20% were Filipino, 18% south Asia and 14% Vietnamese. Overall, 57% of children had experienced caries. The mean number per child of decayed, missing or filled teeth was 2.67. In total, 32% of children needed dental treatment. Overall, there were no statistically significant differences among different demographic groups regarding dental treatment needs or dental health status, except that children born outside Canada had more decayed teeth as compared to their Canadian born counterparts.Conclusion: With the information from this study it is possible to conclude that there is a difference in dental health status between children born in Canada and foreign born children. On average, foreign born children present with poorer dental health status than their native counterparts. Further research should also aim to determine the cause of the disparity, so that a more targeted approach can be taken to improve dental health status.
