Background. The current study tested netrin1-as a reliable inflammatory marker of periodontal disease. Methods. Gingival crevicular fluid (GCF) samples were taken at baseline from 30 systemically healthy individuals. Fifteen subjects had stage II grade A or B periodontitis, and 15 were periodontally and clinically healthy. Whole-mouth periodontal parameters [probing depth (PD), clinical attachment loss (CAL), plaque index (PI), and gingival index (GI)] were recorded. The GCF samples were recollected, and clinical parameters were re-recorded after six weeks following full-mouth scaling and root planing (SRP) in the periodontitis group. Results. Netrin1-GCF levels were significantly lower in periodontitis patients than periodontally healthy individuals at baseline, with a significant increase in netrin1-GCF levels after SRP (P<0. 05). Conclusion. Netrin1-may have a significant role in the inflammatory process of chronic periodontitis,thus, it could be a promising anti-inflammatory marker in periodontal disease.

Background. The present study evaluated the prevalence of severe periodontitis (SP) and determined the possible relevant risk factors among patients referred to the Periodontology Department at the Dental Care Center of the Odontostomatology Training and Research Unit of Abidjan, in Cô, te d’, Ivoire. Methods. This retrospective observational study was based on 1087 patients data aged 18‒, 80 years, who were treated in the periodontology department from December 2008 to December 2018. Severe periodontitis (stages III or IV) was defined as interdental clinical attachment loss (CAL)>5 mm at two non-adjacent teeth. Two groups were considered: patients with severe periodontitis (test) or without severe periodontitis (control). Differences between the two groups were tested using the chi-squared test and ANOVA. Furthermore, logistic regression analysis was used to model the relationship between the severity of periodontitis and covariables as potential risk indicators. Results. 43. 4% of patients had severe periodontitis with a mean CAL of 6. 89 mm. SP was associated with age (P=0. 004), socioeconomic status (P=0. 005), smoking habits (P=0. 000), brushing frequency (P=0. 000), the number of mobile teeth (P<0. 001), and the number of lost teeth (P<0. 001). Logistic regression analysis showed that having at least five mobile teeth (OR= 4. 11, 95% CI: 2. 95‒, 5. 73) and/ or five missing teeth (OR=2. 60, 95% CI: 1. 85‒, 3. 66) were independent risk indicators for severe periodontal disease. Conclusion. This Ivorian sample presented a high prevalence of severe periodontal diseases. Therefore, proper public health measures would allow early detection, with targeted and effective treatment of the Ivorian population.

Background. Inferior alveolar nerve damage can lead to mild to severe paresthesia and even facial pain. One of the treatments considered today for the reconstruction and treatment of damaged peripheral nerves is the use of vitamin supplements. This study aimed to evaluate the effect of vitamin B complex supplementation on pain and sensory problems following mandibular implant placement surgery. Methods. In this single-blind clinical trial, 46 patients applying for implant placement, who were eligible for the study, were evaluated. All the patients were examined for sensory facial injury and inferior alveolar nerve injury within 24 hours after implant placement. The nerve damage was recorded by AI (asymmetry index) in the initial examination. Patients who reported clinical and radiographic signs of nerve damage due to implant or drill impingement of the nerve canal were excluded from the study and promptly treated with anti-inflammatory protocols. Then the patients were randomly divided into control (n=23) and intervention (n=23) groups. Patients in the control group received routine treatment after implantation, and patients in the intervention group received vitamin B complex pills in addition to routine treatment. A placebo was used to eliminate the inductive effect of the drug in the control group. Follow-up of patients was performed at intervals of 14 days and 1, 2, and 3 months after treatment. Data analysis was performed using SPSS 24 and Kruskal-Wallis, Wilcoxon, and chisquared tests Results. In both groups, a decreasing trend in pain intensity was observed for up to three months. There were no significant differences between the mean pain intensity in the intervention and control groups at all the follow-up intervals. In both groups, a decrease in the rate of paresthesia was observed during the-3month follow-up. The mean of paresthesia in the two groups was not significantly different at any follow-up interval. Conclusion. Vitamin B complex might not affect pain intensity and paresthesia after implant surgery.

Background. The maxillary palatine process (MPP) is an excellent source of autogenous bone transplants for anterior maxillary reconstruction. This research aimed to determine the quantity and quality of accessible MPP as a donor location. Methods. Cone-beam computed tomography (CBCT) scans of patients referred to the School of Dentistry were evaluated by a certified examiner. The harvestable MPP was defined as the space between the distal surfaces of maxillary first premolars. OnDemand 3D Imaging software was used to determine bone properties. SPSS software was used to investigate the following variables: Bone characteristics are correlated with age and gender, accessible volume, and palatal width and height. P<0. 05 was defined as the level of statistical significance. Results. This study was performed on CBCT scans of 81 subjects (41 females and 40 males). MPP volume and palatal heights were 0. 53±, 1. 33 cm3 and 5. 51±, 20. 86 mm, respectively. Maximum bone density was observed around lateral incisors. Palatal width was 2. 42±, 33. 81 mm between canines and 2. 66±, 41. 81 mm between premolars. The MPP volume was significantly greater in males (P<0. 001). Additionally, there was a positive correlation between the volume and palatal width (P<0. 05). Conclusion. Within the constraints of this research, there is a limited supply of MMP accessible for use as a graft source, and it is best suited for treating localized bone lesions. The favorable link between palatal breadth and harvestable volume aids the surgeon in estimating the quantity of bone accessible during the first evaluation.

Background. Peri-implantitis is an infectious disease that affects the tissues around dental implants, with clinical signs of inflammation and irreversible loss of supporting bone. This study aimed to compare the effect of sterile topical tetracycline ophthalmic ointment as an adjuvant to mechanical debridement with mechanical debridement alone in the treatment of peri-implantitis. Methods. In this single-blind randomized clinical trial, 32 patients (16 patients in each group) with peri-implantitis were treated topically using sterile tetracycline ophthalmic ointment. Four clinical parameters, including modified bleeding index (mBI), modified plaque index (mPI), probing depth (PD), and clinical attachment level (CAL), were measured at baseline and at 3-and 6-month follow-up intervals. Results. PD reduction was statistically significant after 3 and 6 months in the test and control groups (P=0. 001). Also, mPI and mBI reduction rates were significant in the test and control groups (P=0. 001) after 3 and 6 months. However, in all the samples in the two groups, the mean of CAL before and after treatment was constant, with no significant difference (P>0. 05). Conclusion. Using sterile ocular tetracycline ointment could be an adjunctive treatment in improving and enhancing the therapeutic effects of mechanical debridement in the treatment of peri-implantitis.

Background. This clinical trial evaluated the effect of coenzyme Q10 supplementation along with scaling and root planing (SRP) on periodontal and gingival indices in controlled diabetic patients. Methods. Forty-two diabetic patients (controlled type), referred to the Department of Periodontics with chronic periodontitis and eligible for the study, were included in the study. Patients suffering from chronic periodontitis with a probing pocket depth of ≥, 5 mm in different quadrants of the oral cavity with radiographic evidence of bone loss were included in the present randomized, double-masked, placebo-controlled clinical trial. The subjects were instructed to take one capsule of coenzyme Q10 or a placebo every day for 30 days following SRP. Clinical parameters, i. e., plaque index (PI), gingival index (GI), bleeding on probing (BOP), clinical attachment level (CAL), and probing pocket depth (PPD), were recorded at baseline and four weeks after treatment by two masked and calibrated examiners. The study results were reported as (mean ±,standard deviations) and frequencies (percentages). Results. One month after the intervention, PPD, CAL, BOP, and PI indices in the intervention group were significantly lower than those in the control group. One month after the intervention, the GI was similar in both groups. A significant decrease was observed in the GI in both groups after the intervention. Conclusion. The results of the present study showed that Q10 orally with scaling and root planing in patients with controlled diabetes with chronic periodontitis might accelerate the treatment process and significantly reduce the pocket depths.

Periodontitis can lead to the loss of hard and soft tissues of the oral cavity. Dental implants have become a reliable treatment modality in recent times, especially with the evolution of digital technology such as CBCT, implant planning software, computer-assisted manufacturing, and guided implant surgery. Documentation of such advancements and their clinical implications would add to the existing knowledge on implant dentistry, encouraging dentists to approach complex implant surgeries confidently. This paper discusses the rehabilitation of missing teeth by applying computerassisted guided implant placement in two cases with deficient bone volume anteriorly and posteriorly in the maxilla, respectively. Digital planning and careful execution have resulted in precise implant placement and complete osseointegration. In these cases, we could devise treatment plans with both anatomical and prosthetic considerations while being minimally invasive and more predictable, with shorter treatment time and greater patient comfort.

Chloroform is used widely in endodontic treatments for solving gutta-percha points, but it can have destructive effects if it comes in to contact with oral mucosa. This article presents a case of necrotic ulcer of palatal and buccal mucosa due to injudicious use of chloroform in endodontic treatment, which has caused severe destruction in maxilla. A conservative treatment method of repeated curettage and irrigation was used and although the lesion healed completely, it had major effects on the patient’, s quality of life including loss of two teeth. It is important that dentist be aware of the devastating effects of imprudent application of various chemicals used in dentistry. The conservative treatment used for this case can be helpful option for similar cases.

Many traumatic events lead to bone loss in different areas of the dental ridge. These traumatic events include tooth loss, sinus pneumatization, periodontal disease, etc. 1 Bone deficiency in different areas is problematic in terms of implant placement, necessitating horizontal bone augmentation and socket preservation methods to improve hard tissue conditions in the area. 2 Changes in histological, histomorphometric, and radiographic properties of hard tissue in the area of implant placement affect many parameters of implant success. 3 Improving characteristics such as alkaline phosphatase enzyme activity and the rate at which new living bone is formed and its pattern of mineralization and trabeculae are essential for achieving a high success rate for implants placed in the area. 3 Many destructive processes in dental ridge areas, in addition to microbial etiology, involve the response of host cells through inflammatory mediators. As a potent inflammatory mediator, IL-1 is involved in many of the body’, s inflammatory processes and is responsible for many restorative outcomes of therapeutic interventions in the implant area. 4 This mediator is released in physiological amounts from different cells such as macrophages in the area and affects the progression of inflammation and ultimate tissue repair. 5 However, in high amounts, it causes more inflammation and destructive processes, including bone loss...
