Purpose The goal of this study was to evaluate the incidence of postoperative wound infection and timing of mandibular third molar removal in bilateral sagittal split osteotomy (BSSO). Materials and methods This wis a prospective, single-blinded, randomized, split-mouth clinical trial. All patients were divided into two groups: Group I, where pre-operative removal of the third molars were done 6 months prior to BSSO and Group II, where intra-operative removal of contralateral third molars were done for the same patients during the osteotomy. The primary outcome variable studied was postoperative infection rate and the secondary outcome variable was bad split during BSSO. Results Among the seventy five patients (150 sites), one site in group II developed infection whereas none of the sites in group I developed infection (p = 1.000). No sites had bad split in both the groups. Conclusion The results from the present study show that there is no difference between the presence or absence of mandibular third molars on post-operative wound infection following bilateral sagittal split osteotomy, and the authors hence suggest removing third molars during BSSO for patient comfort.

Implant therapy is a treatment option to ensure prosthesis survival rate and it is also done as a fixed dental prosthesis for replacing single and multiunit gaps. Posterior maxilla often has insufficient bone quality and quantity; for this reason it makes implant placement challenging in the site. Posterior edentulous maxilla presents special challenges to implant surgeons that are unique to this region compared to other regions of the maxilla. Thus, the aim of this study is to determine the common implant dimensions used in posterior maxilla. Completed case sheets were collected from a private dental hospital software system. Case sheets were taken from June 2019 to March 2020. Data was retrieved and evaluated by two reviewers. The parameters taken were patients, age groups, gender, teeth indicated for implants (maxillary premolars and molars), implant height, and implant width. Two-hundred fifty-four implants have been placed on the posterior maxilla of which 139 were premolars and 115 were molars. There was no statistical significance between the implants placed in both males and females (p value: 0.274). Between the age groups, the highest number of implants was seen in 41-60 years (n = 146) followed by 17-40 years (n = 78) and finally61 years (n = 30). The p value was 0.000, which was statistically significant. Various implant sizes for posterior maxilla have been introduced due to its challenging site. Thus in our study, we can see there is a difference in sizes for premolars and molars. Implant dimensions with increased height are used in the premolars compared to the molars. Implant dimensions with increased width are used in the molars compared to the premolars. In general, implant width and implant height can range from 3.6 to 4.5 mm and implant height ranging from 9.50 to 12.00 mm.

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.

Aim The aim of the current study is to assess and evaluate the effectiveness of concentrated growth factors on wound healing after implant placement procedures. Methodology Twenty-four patients who underwent implant placement were included in the study and were divided into two groups (group 1 = non-CGF group; group 2 = CGF group). Conventional implant placement was done in both the groups followed by placement of CGF membrane and closure using 3-0 silk in the CGF group and only closure using 3-0 silk sutures in the control group. The patients were asked to report on the 3rd and 7th day respectively and the wound healing was assessed using an early wound healing index given by Lorenzo Marini. Statistical analysis Shapiro-Wilk test was used to test the normality of the test, which was found to deviate from normal distribution and hence Mann-Whitney U test was employed to evaluate the statistical significance of the two independent samples. Results The mean ± SD was found to be 6.17 ± 2.04 for the control (group 1) and 5.67 ± 0.51 for CGF group (group 2) on the 3rd day. The mean and SD of control group and test group on the 7th day was 7 ± 1.55 and 9.33 ± 1.63, respectively. The difference between the groups on the 7th day was found to be statistically significant (P value Conclusion Concentrated growth factor application had positive effects on surgical wound healing after implant placement.

Rehabilitation with dental implants is, without doubt, an ordained technique. The clinical utilization of dental implants has accelerated in recent years, and new applications continue to emerge. This retrospective study aims to report the implant dimensions commonly used for the posterior mandibular region. It was done at Saveetha Dental College and Hospitals. A total of 391 patients with 670 implant sites within the 20-80 age group who had undergone implant placement were included in the study. The case sheets of patients were obtained from patient information archives. The data on each patient were obtained and tabulated. Out of the 391 patients, 52.2% were males and 47.8%% were females; 33.3% belonged to the35 age group, 34.5% belonged to the 35-46 age group, and 32.2% belonged to the46 age group. The prevalence rate of replacement for mandibular molars was 85.2%; for mandibular premolars, 14.8%. Implant dimensions for posterior mandibles were found to differ based on gender and age group. Males had a greater mean implant width compared to females. Implant dimensions with increased height were used in premolars compared to molars. Implant dimensions with increased width were used in molars compared to premolars. In general, implant width ranged from 3.3 to 5 mm and implant height ranged from 9.5 to 13 mm in the mandibular molar region.

The aim of this study was to evaluate the accuracy/dimensional stability of High-rigid vinyl polysiloxane, polyvinyl siloxane, and polyether impression materials in full arch implant-supported prosthesis. Custom acrylic trays were made on a stone replica of the reference die. Two groups were present in this study: splinting and nonsplinting. A total of 30 samples of 15 for each group were made. Impressions were made and poured with type IV dental stone to obtain experimental casts and were evaluated for dimensional stability and accuracy by measuring with a coordinate measuring machine (CMM) in three dimensions (X, Y, and Z), and a verification jig was fabricated to check the accuracy both clinically and radiographically. Differences in measurements were analyzed using independent t-tests, analysis of variance, and chi-square tests. In terms of dimensional stability, the lowest mean deviation was found in casts made from open tray splinting and nonsplinting and within the impression materials (p > 0.05). But, significant differences (p > 0.05) were obtained with splinting over nonsplinting in terms of accurate fit of the verification jig. This study concludes that polyether material showed less deviation from the reference model, followed by High-rigid VPS and PVS. As results were statistically not significant, all the three impression materials can be used for making full-arch implant-supported prostheses. Splinting obtained more accurate casts over nonsplinting.

Osteoplasty is a surgical procedure for reshaping or recontouring bone. As dental implants are the most commonly preferred treatment for prosthetic rehabilitation, adequate bone height and width are important prerequisites for a successful implant. There is continuous resorption of the alveolar crestal region after extraction of the tooth, which may form sharp edges or sharp bony margins. Osteoplasty is required in such cases to remove the sharp bony margins and flatten the alveolar bone so as to provide increased stability of the implant in the socket. The aim of this retrospective, university-based study was to assess the requirement of osteoplasty in dental implant surgery. Data of patients who underwent implant surgery were collected. A total of 554 patients (331 males and 223 females) with 1,044 implant sites were included. The data were further sorted with respect to age, gender, implant site, and requirement of osteoplasty, and analyzed using SPSS software. The mean age of the patients was 42.70 ± 13.03. A chi-square test assessed association and correlation. The requirement of osteoplasty was higher in the mandibular posterior region (42.2%) than in any other clinical site. In comparison with gender, the requirement was significantly higher in males than in females.

To assess the frequency of self-reported oral cancer and associated factors among individuals with type 2 diabetes (T2D) at a tertiary care diabetes centre in South India.Individuals with T2D who reported that they had oral cancer were included from the Diabetes Electronic Medical Records (DEMR) database. To assess the association of oral cancer with T2D, a retrospective nested case-control study design was adopted. Individuals with T2D and oral cancer diagnosed after the diagnosis of T2D (n = 78) were considered 'cases', while T2D without oral cancer were considered 'controls' (312) [in a ratio of 1:4 for cases and controls]. The cases and controls were matched for age, gender and duration of diabetes. Logistic regression was used to model predictors of oral cancer in T2D patients.Oral cancer was reported in 78 out of 379,138 (0.02%) individuals with T2D registered at the centre. Logistic regression analysis showed that a HbA1c value ≥ 9% had a significant association with oral cancer with an odds ratio of 2.3 (95% CI: 1.2-4.6) after adjusting for confounding factors. Among individuals with T2D, higher frequency of oral cancer prevalence and risk was observed among those who used any form of tobacco (32.6%, OR = 2.52, 95% CI: 1.5-4.3), consumed alcohol (29.2%, OR = 2.01, 95% CI: 1.2-3.3), and those with hypertension (23.9%, OR = 2.05, 95% CI: 1.2-3.6) and hypertriglyceridemia (24.7%, OR = 1.66, 95% CI: 1.01-2.7). Significant independent predictors of oral cancer among T2D were tobacco use (OR = 2.06, 95% CI: 1.1-4.00), high HbA1c (OR = 1.3, 95% CI: 1.03-1.5), hypertension (OR = 2.3, 95% CI: 1.3-4.2) and insulin use (OR = 1.8, 95% CI: 1.03-3.2).Regular dental check-ups as part of the follow-up for individuals with T2D will identify and diagnose oral cancer earlier. Further research is required to assess the physiological and biological mechanisms leading to oral cancer in individuals with T2D.

Oral cancer and diabetes are highly prevalent among the Indian population and are part of the top four non-communicable diseases responsible for mortality and morbidity. Their numbers are so great that they pose a unique burden to the socioeconomic growth of the country. In recent years, there has been an increase in the number of studies examining the role of diabetes in oral cancer reporting co-existence of diabetes and cancer. There is also growing evidence of a higher risk for developing a number of cancers among individuals with diabetes, including pancreatic, liver, gynecologic, colorectal, oral and breast cancer, and consequently 'diabetic oncopathy' is emerging as one of the complications of diabetes. Diabetes may lead to the development of cancer through oxidative damage leading to accumulation of DNA mutations and/or through immune dysfunction, which predisposes to viral infection. Cancer and diabetes may co-occur due to shared risk factors such as increased insulin-like growth factor-1 and obesity, but there is no clear biologic link between the two disorders. This literature review aims to review the evidence showing the current burden of two non-communicable diseases, diabetes and oral cancer and their potential association, with particular reference to India.
