Brief Summary:
It is a randomized clinical trial in which two different types of full coverage restoration in used to restore hypomineralized first permanent molar and protect the remaining tooth structure in patients with molar incisor hypomineralization one group is covered with CAD-CAM milled poly methyl methacrylate crowns and the other group is covered with cast metal copings CAC using nickel chromium alloy and there will be a nine months follow up
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
Patients 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
Patients 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
Patients 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
Patients 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
1 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
2 Behavior management of the patient preparation and administration of local anesthesia is done
3 Preparation For PMMA crowns Removal of any caries associated to the molar and then reduction of the molar 1mm all round the molar and 15mm 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 05 07 mm all round the molar and 1 15mm occlusally and impression is taken for upper and lower jaws after reduction for crown fabrication
4 Temporary crown are fabricated and cemented using zinc oxide and eugenol
5 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
6 Evaluation of quality of both crowns is checked by patients satisfaction comfort and function proper occlusion and proximal contact margins of the crowns and coverage of all surfaces adequately
7 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 patients 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
