Brief summary

The aim of this clinical trial is to evaluate the influence of presurgical patient's diagrammatic illustration of mandibular third molar (Wisdom tooth) surgery on degrees of psychological stress.

Detailed description

Psychological stress is a common factor accompanied with surgeries in most situations, and mandibular third molar (Wisdom tooth (WT)) surgery couldn't be an exception. Saliva was proven as a valid carrier that could be used to track the levels of cortisol representing the degree of patient's provoked stress. Patient orientation and presurgical diagrammatic illustration of the steps of WT surgery are very important aspects for patient preparation, yet, may be potential stress triggers as well. This study aims to figure out if patients are exposed to illustrations that shows the mandibular third molar surgery before having the surgery would aggravate their stress or may relieve it considering orientation and relative absence of fear of unknown.

Interventions

OTHERPresurgical Diagrammatic Illustration for Mandibular Third Molar Surgery

The handling surgeon will show the patient (in the study group) a diagrammatic illustration for surgical steps of mandibular third molar extraction. This diagrammatic illustration includes flap raising, bone guttering, coronal and radicular tooth sectioning, and flap closure.

Masking description

Both the participant and the surgeon are not blinded to the study predictor variable as they both witness the presurgical illustration (introduced to the study group). The laboratory chemist that will analyze the salivary cortisol is blinded to both arms. This means that the chemist does not know whether the saliva sample is drawn from a patient in the control or the study groups.

Inclusion criteria

* Healthy patients (American Society of Anesthesiologists Class I), * Patients demanding extraction of their mandibular third molar, * Mandibular third molars requiring flap raising, bone removal, coronal and radicular sectioning (Modified Parant Scale Class IV), * Patients accepting their saliva sampling prior to and after surgery.

Exclusion criteria

* Acutely painful mandibular third molars on clinical examination, * Pericoronal and/or active periapical and/or active periodontal pathologies on clinical and radiographic examinations, * Patients using steroids, * Psychiatric patients, * Smokers, * Pregnant patients, and/or those observing their menstruation, * Patients with conditions of altered cortisol secretion (such as Addison's disease, Cushing's syndrome, and congenital adrenal hyperplasia), * Patients with altered secretion of saliva (such as due to using atropine, calcium channel blockers, antidepressants, antihistamines, Sjogren's syndrome, and radiotherapy). * Patients who are overtly anxious about dental treatment (scoring \>19 on the Modified Dental Anxiety Scale).

Design outcomes

Primary

MeasureTime frameDescription
Salivary Cortisol Level (in ng/mL)45 minutes before surgery, and 30 minutes after surgery.Amount of salivary cortisol found in patients' saliva is considered directly proportional to degree of psychological stress.

Secondary

MeasureTime frameDescription
Duration of Surgery (in minutes)Same time of surgeryTime taken for each surgery will be recorded starting from flap incision to end of last closing suture knot.
