Detailed Description
STUDY POPULATION Sixty (60) hypomineralized molars in patients suffering from molar incisor hypomineralization (MIH) will be randomly selected to share in this study from the out-patient clinic of pedodontics department, Faculty of dentistry, Ain Shams University.
Patient's approval :
All patients and parents will be informed in details about the nature of the investigation and the purpose of the study. They will agree to take part in the study and the parent will sign an informed consent form and the child will have an assent form.
All reasonable steps to protect the security of the personal information and privacy of the patient protected health information will be taken.
All patients will be notice about their privacy practices, their legal duties and their rights.
All patients will be informed about their benefits from research that will be obtaining a restoration to restore and protect the hypomineralized first permanent molars.
Patient's history:
Precise medical, dental and family histories will be taken from all patients through a direct interview and diagnostic sheet.
Parent will be asked about all the possible causes that might cause the molar incisor hypomineralizaion since pregnancy and during the first three years of his life (prenatal, perinatal and postnatal).
Patient's Examination:
- Extra-oral examination: it will be performed following routine procedures to detect any facial abnormality, temporomandibular joint abnormality, any sign of inflammation, pathology or any soft or hard tissue abnormalities.
- Intra oral examination: it will be performed following routine procedures to examine the sound and affected teeth, soft tissue swelling or fistulae, the occlusion and occlusal relation and proximal contacts, the periodontal status and any other anomalies.
Radiographic Evaluation:
Panoramic and peri-apical radiograph for the molar which is indicated to be included on the trial will be taken to the patients preoperatively to evaluate the pulp status, the supporting bone and to ensure that the patients are free from any pathological lesions and to evaluate the position and development of the second permanent molars.
Patient's Grouping:
Selected patients will be randomly divided into two groups:
- Group (I): patients will receive CAD-CAM milled PMMA crown.
- Group (II): patients will receive cast metal coping using nickel chromium alloy.
STUDY PROCEDURE
Clinical steps:
Half of the molars will receive CAD-CAM milled PMMA crown and the other half will receive cast adhesive metal coping using nickel chromium alloy randomly.
- After proper intraoral and radiographic examination impression of upper and lower arches was made for fabrication of temporary crowns to protect the teeth till fabrication of crowns are finished and the crowns are delivered to the patient.
- Behavior management of the patient, preparation and administration of local anesthesia is done.
Preparation For PMMA crowns Removal of any caries associated to the molar and then reduction of the molar (1mm) all round the molar and (1.5mm) occlusally and impression is taken for upper and lower jaws after reduction for crown fabrication.
For Cast Adhesive Coping (CAC) Removal of any caries associated to the molar and then reduction of the molar (0.5: 0.7 mm) all round the molar and (1: 1.5mm) occlusally and impression is taken for upper and lower jaws after reduction for crown fabrication.
- Temporary crown are fabricated and cemented using zinc oxide and eugenol.
Delivery and Cementation For PMMA crown After crown is fabricated, the tooth is cleaned, dried and isolated and cementation is done using Self Etch Resin Cement.
For Cast Adhesive Coping (CAC) After crown is fabricated, the tooth is cleaned and dried and then etched for 30 seconds and then washed and dried to give chalky white appearance, and then the crown is cemented using dual composite cement.
- Evaluation of quality of both crowns is checked by patient's satisfaction, comfort and function, proper occlusion and proximal contact, margins of the crowns and coverage of all surfaces adequately.
- The patient will be instructed to maintain good oral hygiene and to avoid eating sticky food.
Then the patient will have 1, 3, 6 and 9 months follow up to evaluate the crowns by clinical examination to evaluate margins and clinical performance of the crowns and gingival hygiene, and bitewing radio graph to evaluate margins of the crowns and any recurrent caries, and questionnaire about related quality of life of the patient to evaluate patient's satisfaction and comfort then data is collected and recorded.
The study is expected to be done in 12 months.
STATISTICAL ANALYSIS A proper statistical method will be carried out to compare between CAD-CAM milled PolyMethyl Methacrylate (PMMA) and Cast adhesive metal coping (CAC) for management of extensive first permanent molar defects in patients suffering from MIH.
