Dental erosion and caries are prevalent oral health issues that can have significant consequences. This study aims to evaluate the role of antioxidants (green tea extract, vitamin C, and vitamin E) in reducing dental caries and erosion. A total of 150 participants were divided into one control group and three treatment groups (green tea extract, vitamin C, and vitamin E). The study assessed BEWE (Basic Erosive Wear Examination), DMFT (Decayed, Missing, and Filled Teeth), and baseline demographics. Salivary samples were analyzed for oxidative stress markers and antioxidant levels, and changes in scores were evaluated for participants receiving specific treatments. Statistical significance was determined using a paired t-test. All treatment groups exhibited significant reductions in BEWE and DMFT scores compared to the control group. Specifically, the DMFT for Group A (vitamin C) decreased from 4.2 to 2.8, for Group B (vitamin E) from 4.0 to 2.9, and for Group C (green tea extract) from 4.1 to 3.0. The treatment groups also showed significant decreases in BEWE scores, while the control group exhibited minimal changes. Antioxidants have the potential to serve as effective preventive agents in dental care, significantly reducing dental caries and erosion. Further research is needed to confirm long-term benefits and explore optimal usage.

Introduction: The sinus lift technique is a widely used procedure for the rehabilitation of the atrophic maxilla in terms of height in the posterior regions. Initially, it was performed through a lateral approach with an open window, until a less invasive procedure, the transcrestal elevation, began to be used. Today, this approach is almost exclusively performed, with the lateral approach being reserved for extreme atrophies (1–2 mm in height). Regarding graft material, there have also been modifications over time, evolving from block grafts and particulate autologous bone to mixtures of different materials, and more recently, to graft-free techniques. In these cases, only the pressure from the implant apex and space maintenance contribute to new bone formation within the augmented space. This article presents cases treated with transcrestal sinus lift without graft material, with a follow-up period of up to 15 years. Materials and Methods: Patients who had undergone a transcrestal sinus lift without graft material and had a minimum follow-up of 10 years and a maximum of 15 years were consecutively recruited. Follow-up evaluations were conducted every six months, assessing bone gain over the implant apex and its stability over time, as well as mesial and distal crestal bone loss and implant survival. Results: A total of 27 patients who received 45 implants meeting the inclusion criteria were recruited. Among them, 44.4% were women, with a mean age of 68 years (±4.5). The mean initial bone height at implant placement sites was 5.75 mm (±1.11), ranging from 2.07 to 7.10 mm. At the end of the follow-up period, which had a mean duration of 12.8 years (±1.32), ranging from 10 to 15 years, the final mean bone volume at the implant site (implant length + bone gain) was 8.99 mm (±1.91). The mean bone gain over the apex across all implants was 4.21 mm (±1.89). Regarding bone loss, the mean mesial crestal bone loss across all implants was 0.66 mm (±0.46), with a range of 0 to 2.21 mm, while the mean distal crestal bone loss was 0.87 mm (±0.53 mm), ranging from 0 to 3.03 mm. Conclusions: Transcrestal sinus lift without graft material, using short and extra-short implants along with a specific drilling sequence, is a safe and predictable technique, even in the long term. The results of this study, with a follow-up period of 10 to 15 years, support its effectiveness and reliability.

A coral-pink gingiva reflects the normal health of blood vessels and the proper width of keratinized tissues, both of which are essential for dental and facial aesthetics. Gingival pigmentation is caused by melanin granules and manifesting as uneven brown, light brown, or deep purplish discoloration and may necessitate cosmetic therapy. Among the various treatment modalities, diode laser and bur ablation are commonly used for gingival depigmentation. Moreover, platelet-rich plasma (PRP), which delivers a supra-physiological dose of growth factors, has emerged as a promising adjunct to accelerate wound healing in periodontal aesthetic procedures. This article presents two case reports of two female patients with gingival pigmentation, who were treated at King Abdullah Medical City Specialist Hospital using a split-mouth approach. In one patient, diode laser ablation was performed on the lower anterior gingiva and bur ablation on the upper anterior region; in the other, laser and bur ablation were applied in different quadrants. Immediately after ablation, injectable PRP was administered into the depigmented areas. Healing was evaluated using the Healing Index on days one, three, seven, 14, and 30, and pigmentation was assessed preoperatively and on day 30 with the Dummett-Gupta Oral Pigmentation Index. The results of the two case reports suggest that adjunctive PRP may enhance wound healing following gingival depigmentation, necessitating further clinical trials with standardized protocols and larger sample sizes.

Maxillary lateral incisors agenesis (MLIA) is a common dental anomaly often managed through space opening to accommodate prosthetic replacement. This approach integrates orthodontic and prosthodontic techniques to restore function and aesthetics. This article explores advancements in space opening treatment, with an emphasis on prosthetic rehabilitation using implant and bridge, and highlights the role of digital dentistry in improving outcomes. Recent evidence-based studies provide insights into the clinical decision-making process and long-term success rates.
