Brief Summary

Molar incisor hypomineralization (MIH) is one of the developmental enamel defect which is characterized by demarcated, qualitative defects of enamel of systemic origin affecting one to four first permanent molars (FPMs) and frequently associated with incisor involvement. Similar lesions can be seen in second primary molars and their presence has been reported as a predictive factor for developing MIH. Although the exact etiology of MIH is unclear, it is likely to be multi-factorial. Possible etiological factors of MIH are systemic conditions as pneumonia, upper respiratory tract infections, asthma, otitis media, hypoxia, high fever, hypocalcemia and exposure to antibiotics as amoxicillin. The prevalence of MIH has been reported from several studies to be between 2.8 and 40.2 %, with the mean approximately 15 %. MIH is considered as a common clinical problem by several epidemiological studies from many countries. Clinical presentation of MIH can include white, creamy and yellow-brown opacities, irregular areas of post eruptive breakdown, which can be mistaken diagnosed as hypoplasia or atypical caries. The condition is usually associated with a high disease burden, leading to pain, infection and tooth loss. Teeth affected by MIH are at high risk of rapid caries development and progression, rapid wear and enamel breakdown. Severely affected enamel disintegrates under masticatory forces resulting in post-eruptive breakdown (PEB), which is also a characteristic feature of MIH-affected teeth. These teeth require treatment, ranging from prevention to restorations and extractions, often under general anesthesia. A multidisciplinary cooperation among clinicians is often required, particularly for extractions of first permanent molars, when orthodontic consequences need to be considered. To evaluate the effect of this condition, questionnaires of dentists and dental professionals have been carried out in various countries, including those in Europe, Australia and New Zealand, Malaysia, Iraq, Iran and Saudi Arabian. These have generally revealed that MIH has been frequently encountered in clinical practice, particularly by dental professionals who treat children and that there is a need for further training for the condition. To date dental clinicians' concerns regarding MIH have not been extensively assessed in Egypt.

Keywords

Molar incisor hypomineralization; General dental practitioners; Perception; knowledge; Oral health

Outcome Measures

Primary Outcomes (1)

• knowledge of Egyptian dental practitioners regarding molar-incisor hypomineralization

  The tool used for measuring the primary outcome is a self-administered questionnaire that was fulfilled by the study participants

  1 year

Study Arms (1)

Dental practitioners (general, specialists or students)

Two self-administered questionnaires will be used in the study one to general practitioners and specialists and another one with a plain language describing the study will be distributed to the fifth year dental students in Egypt with total 1000 dentist to assess their knowledge, awareness and perception regarding MIH.

Other: self-administered questionnaire

Interventions

self-administered questionnaire OTHER

Self-administered questionnaires with plain language statements and brief description of the clinical features and photographs of MIH were used to determine the knowledge, awareness and perception regarding the prevalence, severity, etiology and treatment modalities of molar-incisor hypomineralization (MIH) among Egyptian fifth year dental students, general dental practitioners and dental specialists. There were two routes for delivering the questionnaire either as online questionnaire sent to the participants by email or as a hard copy that is hand delivered.

Dental practitioners (general, specialists or students)
