| Abstract|| |
Context: Molar-incisor hypomineralization (MIH) is a defect existing in the form of demarcated and opaque lesions and in severe cases with posteruptive enamel breakdown. There is a lack of knowledge, learning, and practice on MIH in pediatric dentistry. Aims: This study aimed to identify the knowledge, attitude, and practice on MIH among postgraduates and faculty members of K.M. Shah Dental College and Hospital, Vadodara, Gujarat, India. Settings and Design: A questionnaire-based study was conducted among the dental staff and postgraduate students of K.M. Shah Dental College. Subjects and Methods: The questionnaire was hand-delivered to all 142 participants, and they were asked to fill it within 5 working days. The questionnaire included demographic information, prevalence, incidence, and severity of MIH in Vadodara City. Statistical Analysis Used: Data analysis was done using SPSS version 20.0 (SPSS Inc., Chicago, IL, USA). The data were found to be normal by the Kolmogorov–Smirnov test. Intergroup comparison was done using the Chi-square test for proportions and percentages (qualitative data). Results: 43.3% of the respondents could not implement the clinical criteria to diagnose MIH, 92.5% of the respondents recommended to include MIH-associated case studies in the curriculum, 95% of the respondents recommended to conduct awareness programs, and 40.5% of the respondents indicated a lack of knowledge as a barrier for performing MIH management. Conclusions: There is a need for dentists to attend continuing dental education programs and various awareness programs on MIH and to introduce in-depth information on MIH-etiology and its treatment into the dental curriculum.

| Introduction|| |
Molar-incisor hypomineralization (MIH) has been coined byWeerheijm et al. (2001). In the form of demarcation and opaque lesions, it is basically a tooth deformity. MIH results in a posteruptive breakdown of the enamel in severe cases. MIH is an enamel defect of a qualitative type, distinguished primarily as a hypomineralized type. Clinically, it is observed that the hypomineralized enamel is soft, porous, and brittle due to which it can easily be peeled off under the forces of mastication. In some cases, enamel peeling (posteruptive enamel breakdown) is so rapid that it appears as if the enamel was not formed initially. This condition may be confused with hypoplasia; however, in hypoplasia, the boundaries to the normal enamel are smooth, contrary to the posteruptive enamel breakdown condition, where the boundaries to the normal enamel are irregular. The clinical appearance of the enamel defects may vary from white to yellow or brownish; however, the defects frequently depict an acute demarcation between the affected enamel and sound enamel. Moreover, the condition of MIH is also confused with fluorosis or amelogenesis imperfecta. This is because there is a lack of knowledge, learning, and practice on MIH in pediatric dentistry. Hence, the present study was conducted to identify the knowledge, attitude, and practice on MIH among postgraduates and faculty members of the institute.
Objectives of this study
- To evaluate knowledge, attitude, and practice regarding the MIH among the teaching faculty members and postgraduate students
- To compare the knowledge, attitude, and practice regarding the MIH among the teaching faculty members and postgraduate students.
| Subjects and Methods|| |
A questionnaire survey was conducted among the dental teaching staff, both faculties with basic degree and master's degree and postgraduates, after receiving approvals from the Human Research Ethics Committee of the institution. A group of subject experts were randomly selected and were assigned to validate the questionnaire which was checked by two ways, namely content validity and concurrent validity. The content validity confirms that all the aspects of the tool were covered and the concurrent validity confirms that the tool was valid with more than 95% confidence (t = 1.00 and P = 0.417). A package containing an information brochure about the study, the questionnaire, and a plain language statement describing the study was hand-delivered by the first author to all potential participants (n = 142). An envelope was also included to facilitate responses. Participants were asked to complete the questionnaire in their own time and return it in a sealed envelope within 5 working days. The questionnaire consisted of two sections. In the first section, respondents were asked to provide sociodemographic information including the type of qualification, both undergraduate and postgraduate degrees. The second section included questions regarding perception and recognition of the MIH condition in Vadodara city, prevalence, incidence and severity of the defect, represented by its clinical presentation, clinical experience of MIH, and knowledge of possible etiological factors. The questionnaire also included questions about the prevalence of MIH in the second primary molars, the confidence of the respondents in diagnosing MIH, and views on the need for clinical training on enamel hypomineralization.
The recorded data were compiled and entered into a spreadsheet computer program (Microsoft Excel 2007) and then exported to Data Editor page of SPSS version 20.0 (SPSS Inc., Chicago, IL, USA). The data were found to be normal by the Kolmogorov–Smirnov test. Intergroup comparison was done using the Chi-square test for proportions and percentages (qualitative data). The level of significance was set at 0.05, i.e., statistically significant.
| Results|| |
The sample size of this study was 142, of which 58 were staff members and 84 were postgraduate students. Of the total 142 participants, 22 did not respond (4 staff members and 18 postgraduate students), so total 120 participants were included in the study. The knowledge-based analysis was conducted based on five questions tabulated in [Table 1].

[Table 1] shows that the majority (68.3%) of the respondents showed higher awareness of the fact that MIH is a developmental defect of enamel and it differs from dental fluorosis and hypoplasia, higher percentage (47.5%) of the respondents were able to predict the prevalence between 5% and 10% of MIH in the community, higher percentage (57.5%) of the staff members and postgraduates identified genetic factor as an etiological factor causing MIH, majority (57.5%) of the respondents knew the clinical features of MIH, and higher percentage (43.3%) of the respondents could not implement the standard clinical criteria to diagnose MIH.
[Table 2] shows that higher percentage (45%) of the postgraduate students agreed that MIH represents a clinical problem next to dental caries, whereas 27.5% said no, 17.5% of the postgraduate students were “not very confident” and 17.5% of the staff were “not confident” in diagnosing MIH teeth, higher percentage (37.5%) of the respondents depicted preparedness to diagnose MIH, maximum respondents (92.5%) suggested to include MIH-associated case studies in the undergraduate dental curriculum, and 95% recommended to conduct awareness programs.

From [Table 4], it can be observed that there is a considerable variation regarding opinions and the clinical management of MIH. Hence, practice cannot be compared between both the groups, i.e., staff and postgraduates.

| Discussion|| |
In the present study, we examined the awareness of MIH among dentists in K.M. Shah Dental College and Hospital. The study conducted by Allazzam et al., in 2014, illustrates MIH as a significant clinical problem. The study has illustrated that demineralization of enamel makes the tooth sensitive, which, in turn, makes it vulnerable to caries.
It was observed that as many as 68% of the respondent dentists were able to differentiate MIH from dental fluorosis and hypoplasia. The findings of this study have shown a prevalence rate of MIH to be in between 5% and 10% in our community. The findings are substantiated by Bhaskar and Hegde in 2014 and Parikh et al. in 2012, showing a prevalence rate of 9.46% and 9.2% in their respective studies.
In the present study, dentists indicated that genetic factors cause MIH; also, recent studies indicate that genetic factors are likely to play a significant role in causing MIH (Jeremias et al. in 2013 and Kuhnisch et al. in 2014). On the contrary, Crombie et al. in 2008 reported maternal and child illness as a cause of MIH in their study. It was observed that 32.5% of the dentists reported MIH to be next to dental caries in public health terms and effectively placed it under other oral conditions, such as periodontal disease, dental trauma and oral cancers.
The present study illustrated that many dentists reported yellow/brown opacities as an indication of MIH. This result was found to be consistent with the study carried out by Hussein et al. in 2014. Furthermore, many dentists preferred using composite resin for the restoration of MIH-affected teeth. Bagheri et al. in 2014 reported that similar material has been indicated in the recent survey of Iranian dentists and academics for the restoration of MIH-affected teeth. The study conducted by Lygidakis et al. in 2010 suggests the use of metal as the best restorative option for moderately and severely affected teeth by MIH. It was found that many (37.5%) respondents lacked knowledge on MIH management and not a single patient with MIH was treated by 80% of the respondents.
After comparing knowledge and attitude among staff and PG, it was observed that knowledge on MIH was higher in staff as compared to that of PG [Table 4]. Similarly, after comparing attitude among staff and PG, it was observed that PG showed a more positive attitude in gaining information on MIH as compared to that of staff.
The findings from this study divulge that there is very less exposure to MIH in the undergraduate program of the dental curriculum. Furthermore, despite the growing awareness on MIH, it is yet not covered in depth in the undergraduate dental curriculum. The present study illustrates that without a comprehensive clinical exposure to MIH in the undergraduate training, future dentists will face similar challenges in terms of managing patients with MIH. Due to this, many dentists were found to be not confident enough in diagnosing teeth with MIH. From the findings of the present study, it can be recommended that MIH-associated case studies should be included in the undergraduate curriculum topics of the pediatric dentistry, and awareness program should be carried out to understand MIH by means of continuous dental education programs.
| Conclusions|| |
The present study concludes that dental teaching staff relatively possess a higher knowledge of MIH than the postgraduate students, who relatively showed a more positive attitude for gaining information on MIH. Furthermore, very less exposure to cases of MIH resulted in respondents facing difficulties in properly diagnosing the condition in their dental practice. Hence, it is recommended for the dental professionals to attend continuing dental education programs and various awareness programs based on MIH and to introduce in-depth information on MIH, its etiology, and its treatment into the dental curriculum at the undergraduate level.
