ABSTRACT
BACKGROUND:
Molar incisor hypomineralisation (MIH) is a developmental enamel defect in the first permanent molars and frequently in the incisors. It poses a unique challenge to the dental practitioner because of its nature, clinical presentations and treatment strategies.AIM:
This study assessed the perception of Libyan dentists in Benghazi regarding MIH and its management.DESIGN:
Paper-based, self-administered questionnaires were distributed to dentists in Benghazi, Libya. The questionnaires investigated the awareness of MIH, knowledge of MIH aetiology, clinical challenges of MIH treatment and choices of restorative management. Descriptive statistics, chi-squared test and binary logistic regression analysis were performed at a significance level of ≤.05.RESULTS:
A total of 389 questionnaires were completed and analysed, giving an overall response rate of 76% (389/511). Most participants were female (85%, 332), with an average of 6.05 (SD = 6.24) years of experience. The majority of participants (67%) recognised MIH in their practice. Statistically significant differences in the awareness of MIH and its prevalence were observed according to the type of practice (p ≤ .001) and experience of dentists (p ≤ .001). Dentists working in public dental practice were less familiar with MIH and less likely to report it. Likewise, novice dentists were less aware of MIH than more experienced colleagues. The most reported aetiological factor in MIH was genetics by 60.2% of respondents, followed by environmental contamination (47.6%) and fluorides (42.9%). Most participants (92.3%) considered MIH a clinical problem. Aesthetics and diagnosis were the most reported challenging aspects (59.4% and 44.2%, respectively). The most commonly selected restorative options were high-fluoride glass ionomer cement (43.2%) and preformed metal crowns (41.6%).CONCLUSION:
The majority of participants reported awareness of the existence of MIH condition. Nevertheless, variations in estimating MIH prevalence and its proper treatment, as well as factors influencing its treatment and diagnosis, were recorded. It is recommended that the current dental curriculum is reviewed, and scientific evidence providing dental practitioners with updated information on the diagnosis and clinical management of MIH should be circulated.Key words
