Medical treatment by Muslim doctors will sometimes be influenced by Islamic law and ethics rather than solely medical consideration. Muslim patient’s sometimes need reassurance that modern medicine that offered to them is also acceptable by Islamic law. Orthognathic deformities are condition which associated with discrepancies of the jaw. These deformities resulted from different rates of growth of the maxilla, the mandible or both. Performing cosmetic surgery seems to change the creation of Allah and the original law of changing Allah’s creation is prohibited. In assessing the orthognathic surgery law for patients with this dentofacial defect, the researcher found that the main issues that need to be investigated are the difficulties existed (Masyaqqah) and the level of patient harm in addition to the intention or purpose of performing orthognathic surgery. However, according to the principles of the Islamic jurisprudence, orthognathic surgery is permitted based on the principles such as ad-darar yuzal, al-musyaqqah tajlibu al-taisir, al-darurat tuqaddiru biqadaruha, irtikab akhaf al-dhararain, al-darurat tubihu mahzurat and al-umur bimaqasidiha. Orthognathic surgery can be done because the purpose is to treat defects and restore function. This objective is very consistent with the fiqh rules that stated, every harm and distress should be eliminated.

Surgical extraction of the mandibular third molar is the most common surgical procedure in oral surgery clinic. Adequate postoperative instructions and good patient compliance are important to achieve positive clinical results and minimize complications. The objectives of the study were to determine the percentage of patient compliance towards postoperative care (POC) given by dental clinicians at USIM polyclinic and to identify the association between factors influencing patient compliance towards POC following the surgical extraction of mandibular third molar at USIM polyclinic and patient’s demographic characteristics. A set of questionnaires was disseminated to 16 patients which assessed the patients’ perception on swelling, bleeding, pain, diet, oral hygiene care, medication compliance, clinician’s factors, and patient’s level of understanding and their attitude towards POC. The percentages of patient compliance were represented by descriptive statistics, while the identification of possible factors influencing patient compliance were obtained by performing a Fisher Exact test. All factors give a high percentage of compliance which is more than 60% for all demographic characteristics. There is no association between all factors and demographic characteristics (p-value>0.05). Patient’s compliance is good and demographic characteristics do not appear to be key factors that ensure patient compliance towards POC following surgical extraction of the mandibular third molar.
