ABSTRACT
With the advent of implantology as an important means to rehabilitate the edentulous patients, the neglect over the years post extraction leads to severe bone loss. This can be corrected by grafting procedures. Grafting procedures are complex as it takes into account various factors such as the type of graft material, surgical site, surgeon's skill and the patient's compliance. Totally 20 patients ( male n=10 ; female n=10) were included in the study, 14 patients underwent GBR, 4 patients underwent direct sinus lifts and 2 underwent block grafts. The stress levels of the patient also is an important factor to consider as varying cortisol levels will be detrimental to the healing of the surgical site. Premedication with painkillers and corticosteroids can help patients comply with the treatment and feel less anxious. The stress levels of the patient were assessed using State trait anxiety index, 50.6± 6.9 was the pre-operative stress and 36.95± 9.3 was the post-operative stress. Stress levels were significantly greater before the procedure than after it, according to statistical analysis. The females were significantly having increased stress both pre and post-operatively. Also, the patients in the age group of 41-50 years showed increased amounts of stress.
ABSTRACT
One of the main drawbacks faced by the dental implant surgeons is to assess the healing of the tissues and implant success for patients who are smokers. It is of interest to evaluate inflammatory biomarkers to understand the soft and hard tissue healing between smokers and non-smokers based on levels of IL-6 and STAT-3. This study included totally 20 patients (Group 1 : smokers (n=10) and Group 2: non-smokers (n=10)) undergoing stage-1 implant surgery and collected a tissue sample for the patients to assess the levels of IL-6 and STAT-3. The results indicated that there is a pronounced increase in the biomarkers in patients who are smokers in comparison to non-smokers.
ABSTRACT
This study aimed to perform a cone-beam computed tomography (CBCT) analysis in the Chennai population to check for the prevalence of the canalis sinuosus and its terminal branches in the site of endosseous implant placement in the alveolar ridge of the anterior maxilla. A retrospective analysis was conducted in Saveetha Dental College, Chennai. One hundred (50 male and 50 female) CBCT images that included the maxilla of patients aged 18-65 years were selected at random from the archives of the Oral Implantology Department, which were taken in the period from December 1, 2019 to November 30, 2020. Two examiners assessed all the scans with special training to identify this structure. The CBCTs were examined carefully for the presence of accessory canals and the side of occurrence, gender, relation in proximity to the anterior teeth (central incisors to the first premolar). The diameter of the canal was also noted as either less than 1 mm or greater than 1 mm. Our study showed that accessory canals of the canalis sinuous were identified in a total of 18 patients (4 female, 14 male). This shows that in our study, the prevalence of this structure amongst male patients was 14% and for female patients, it was 4%. This study shows that although the accessory canals of the canalis sinuous in the site of endosseous implant placement are rare, it must not be taken lightly because its occurrence still poses a significant risk of iatrogenic nerve damage, especially during implant placement procedures. In some individuals, the terminal branches of this canal or its accessory canals can sometimes be present in the site of placement of endosseous implants placed in the anterior maxilla. Lack of knowledge and awareness of this structure and the fact that its occurrence is often overlooked due to its rare occurrence causes the potential for iatrogenic damage to the nerve resulting in complications.
