Introduction: Special Care Dentistry (SCD) is a dentistry branch that advocates equal dental Patient with Special Care Needs (PSCN). In several countries, it is a separate specialty. In India, it is still in its infancy. Few studies have explored the dentists' perception regarding SCD.
Aim: To determine the knowledge and attitude about SCD, also the practice measures followed by the dentists in Chennai colleges.
Materials and Methods: This cross-sectional observational study was conducted in three dental colleges in Chennai from September 2019 to October 2019. A total of 230 dentists were enrolled using random sampling. A set of 20 close ended multiple choice questions were formulated and administered to dentists {Undergraduates (UGs) and Postgraduates (PGs)}. Descriptive statistics and Chi-square test was performed using MATLAB software (Mathworks, 2015), with p<0.05.
Results: A 78.8% of respondents got good scores of ≥7 in knowledge based questions, 25.6% of the participants showed overall positive attitude. Educational qualification did not affect respondents’ knowledge and attitude about SCD (p>0.05). Only 21.95% of UGs and 22.31% of the PGs have good self-confidence in treating patients with special needs. More than 80% have not administered Domiciliary Care (DC). A total of 65% of participants denied getting any training in their UGs/PGs curriculum.
Conclusion: Dentists in the present study are aware about SCD. Clinical measures adopted by dentists and their confidence in treating these patients are suboptimal. Training in SCD should become integral part of future dental education.
Disabled population, Domiciliary care, People with special care needs, Special children, Special needs dentistry
Special needs Dentistry/SCD is the management of oral health, especially for patients with special needs, by employing alternate methods (1). The Commission on Dental Accreditation (CODA) considers patients with special needs to be medically, physically, psychologically and socially incapacitated. It recommends specialised training for oral health professionals (2). The British Society of Disability and Oral Health (2006) advocates equal and DC for Special Care Needs (SCN) patients (3).
Census 2011 (updated 2016) shows that India houses 2% of the world’s disabled population (4). According to the Welfare of Differently Abled Tamil Nadu, Chennai’s disabled population is 90,064. The absence of proper oral health care for SCN in India can be attributed to the physical, geographical, and economic barriers accompanied by inadequate clinical infrastructure and sparse training among dentists (5),(6).
Despite the staggering number of dentists in India, World Health Organisation (WHO) 2014 data showed dentists’ ratio to population is 1:10000. Fewer still are trained in treating patients with special needs (5),(7). All India Institute of Medical Sciences (AIIMS) and WHO gave oral healthcare guidelines for PSCN; yet, more concrete initiatives are imperative. SCD is also not part of the academic curriculum given by the Dental Council of India for dental students (8).
Studies exploring the awareness and practice among dentists towards SCD are scarce. The present study is the first multicentric Knowledge, Attitude and Practice (KAP) survey conducted amongst dentists and students in academic settings. The current KAP survey aimed to assess the knowledge and practice measures adopted by dentists in Chennai and to know the various treatment modalities followed by dentists in treating PSCN.
The present cross-sectional observational study was conducted in SRM University, Ramapuram, Chennai, Tamil Nadu, India between September 2019 to October 2019, following the Institutional Review Board’s Ethical Committe approval (RMU/M&HS/SRMDC/2019/PG/007). The reporting of the study followed “STROBE Statement” (9), and a total of 230 participants were included in the study. The study was explained in detail and informed written consent was obtained from the study participants.
Questionnaire
A set of 20 multiple choices (close ended) questions were formulated after the literature search (1),(3),(10). The face and content validation (Content Validation Ration CVR= 0.60) of the questions were done by three oral medicine and two public health dentistry experts (11). Reliability was checked using the test-retest method. Based on the queries and suggestions received, few questions were revised and redistributed amongst the study sample. Overall reliability of the questionnaire was calculated using Cronbach’s alpha and was found to be 0.71 (12). The revised set of 20 questions, as shown in [Annexure 1], were divided into three groups Knowledge (5), Attitude (6), and Practice (9) based questions.
Sample size calculation: Sample size was manually calculated based on the previous survey with prevalance=6.44 Q=1-p 35.6 L precision of the estimate=6.44 Zα=standard normal variate 2=3.84 (13). The present study was conducted among dental students (UGs and PGs) and faculty of three different dental colleges in Chennai, based on the following inclusion and exclusion criteria:
Inclusion criteria: All dentists with at least one year of clinical experience, dentists who were working in colleges, interns attending clinics (UGs), Postgraduate students (PGs) were included in the study.
Exclusion criteria: Dentists with no clinical experience and not working in any institution, duplicate answers, incomplete answers and participants not willing to participate in the study were excluded from the study.
Data Collection
The printed forms were distributed among the voluntary participants. knowledge and attitude based questions were scored with minimum score for each question being 1 and maximum being 5. Opinion based questions were scored using Likert scale (1-5) (14). Scores of knowledge and attitude based questions were added to get an overall score. Overall score was then multiplied by 0.4 and was plotted using a cumulative graph on a scale of 1-10. Participants with score ≥7 was categorised as good knowledge score. Similarly, the scores ≥7 was considered as positive attitude.
Statistical Analysis
Descriptive statistics and Chi-square tests were performed using MATLAB Software (MathsWorks, 2015). Chi-square test was performed to assess the effect of educational qualification on knowledge and Attitude of respondents towards SCD (p-value ≤0.05).
Final data included 205 out of 230 data samples with a response rate of 89.13%. A total of 25 forms were excluded (13 incomplete records, and 12 duplicate answers). Out of 205 respondents, 121 were PGs and 84 were UGs.
Knowledge among Dentists about SCD
A 78.8% of the participants scored ≥7, for knowledge based questions, as shown in (Table/Fig 1). Around 52% UGs and 48% PGs were not aware of the colleges, which offer a course in SCD in India. Majority of the participants (34.15% UGs, 23.97% PGs) were unaware about the practice of DC, as shown in (Table/Fig 2).
Attitude about SCD
A 25.6% dentists scored ≥7 in attitude-based questions (Table/Fig 3). Both PGs and UGs (32.32%, 39.02%) were moderately satisfied with the disability confidence among the dentists in handling special needs patients. While PGs (39.67%) were willing to enroll in SCD course if offered in India, UGs (31.70%) were mostly indecisive. Maximum participants (71.95% UGs, 61.15% PGs) felt the clinical infrastructure for treating PSCN is of fair quality (Table/Fig 4).
Practices Followed by Dentists for PSCN
Most of the respondents (64.41% PGs, 63.41% UGs) answered they had not received any specific training for SCD. Most of the participants (81.70% UGs, 78.69% PGs) had never given DC. Dentists (68.30% UGs, 51.24% PGs), majorly don’t have any specialised equipment in their clinics for treating PSCN (Table/Fig 5).
Association between Educational Qualification and Awareness about SCD
Chi-square test showed no relation between educational qualification (UGs or PGs) and knowledge and attitude of the respondents towards SCD with p=0.519 and p=0.184, respectively (Table/Fig 6).
More elders and disabled people are retaining their natural dentition, which necessitates modifications in routine dental procedures which benefits them (15). Environmental and attitudinal factors are the main barriers that restrict disabled people from getting equal dental care (16). There is a need to have a patient-centric approach towards treatment planning preceded by evidence-based dentistry (10). Dental colleges and academia are the main source of information about SCD. They should include virtual workshops, CDEs, hands on training on SCD as integral part of education, thus empowering students with the confidence to treat PSCN (8).
There are several international surveys conducted among dental healthcare workers about SCD, but only few studies has been conducted in India (Table/Fig 7), especially in dental colleges (2),(13),(15),(17),(18),(19),(20),(21),(22),(23),(24),(25). There is a need to know the level of awareness among students and academicians about SCD.
The participants in the current study had good knowledge about SCD. Majority of the dentists showed neutral to positive attitude towards SCD. Despite this, there is a lack of appropriate clinical infrastructure and training among dentists, which hinders the proper oral healthcare opportunities for PSCN. In this study, knowledge and attitude of the participants were not affected by their educational qualification.
Majority of the participants have moderate level disability confidence in treating SCN patients and are willing to undergo training and attend CDEs if offered in India. The results are similar with that of a survey conducted by Watters AL et al., and Kapoor S et al., (22),(23).
Lack of training and education in the curriculum is the primary deterrent for building confidence among dentists (16). Participants in the present study scored good in knowledge based questions which is in contrast to study by Salama F et al., where only 5% of students had moderate knowledge about SCD (24).
Majority of the participants have limited clinical exposure and have never given DC to patients. Similar to the study by Chadha G et al., dentists in the present study have never attended any formal training during their academic curriculum for SCD and feel the need of more exposure to SCN patients in college life (13). This is in contrast to the study by Kapoor S et al., where students had attended lectures on SCD in their college (23). The participants, share neutral to positive attitude towards SCD, but physical barriers hinder them in providing better oral health care, as also seen by Dighole MS et al., in their study (25).
Limitation(s)
The study’s limitations include a cross-sectional study design, and the smaller sample size, which prevents the generalisation of the results. The close ended format of questionnaire might have lead to response bias.
Participants in the present study had good knowledge about SCD and are open to new information. They lacked practical experience and confidence. Inclusion of SCD in academic curriculum and more clinical exposure will ameliorate students’ attitude and help in building their confidence while treating patients with special needs. Further studies with larger sample size and with pre and posteducational training should be conducted. Studies with evidence-based treatment modifications pertaining to SCD should be encouraged.
