Can natural language processing serve as a consultant in oral surgery?

OBJECTIVE

In this comprehensive evaluation, ten experienced oral surgeon experts posed a total of twenty oral surgery-related questions, including dental implant and tooth extractions, to three distinct Natural Language Processing (NLP)-based chatbot platforms: ChatGPT, Microsoft Bing, and Google Bard. The study aimed to assess the effectiveness of these chatbots in responding to specialized medical questions.

MATERIALS AND METHODS

Two primary evaluation metrics were employed: a Likert Scale (LS) for measuring the accuracy and completeness of responses and a Global Quality Scale (GQS) for evaluating the clarity of responses. Statistical analyses, including one-way analysis of variance (ANOVA) and Post Hoc Tukey, were conducted to assess and compare the performance of the chatbots as rated by the experts.

RESULTS

The results of the study revealed significant differences in the performance of the chatbots. ChatGPT statistically achieved a better mean LS score of 1.4000±0.15986 than Microsoft Bing (1.8750±0.18143) and Google Bards (2.0500±0.12472) (P < 0.001). Additionally, ChatGPT statistically achieved a higher GQS score of 4.4200±0.30111 than Microsoft Bing (3.7550±0.28621) and Google Bards (3.5250±0.22392) (P < 0.001).

CONCLUSIONS

These findings showed the substantial advantage of ChatGPT in effectively addressing oral surgery-related questions with superior accuracy, completeness, and clarity. The study highlights the potential of advanced NLP platforms to enhance information retrieval and communication within the field of oral surgery, reinforcing the utility of such technologies in medical and surgical domains.

Does YouTube Provide High-Quality Information for Patients Regarding Night Guards, Especially for Over-the-Counter Ones?

The aim of this study was to evaluate the quality of the information on YouTube regarding night guards (NGs). YouTube was systematically searched using the keyword "night guards." Two independent reviewers examined the first 100 videos and exclusion criteria were applied. Descriptive characteristics of the remaining 60 videos were recorded. In addition, the purpose, target audience, and source of the included videos were collected. A 12-point content scale (CS) was used to evaluate video content, and the Global Quality Scale (GQS) was used to determine video quality. Statistical analyses were performed using the Kruskal-Wallis and Mann-Whitney tests, and the correlation between scores was evaluated using Spearman rho. Of the included videos, 50% were uploaded by dentists/health institutions, 26% by commercial sources and 24% by laypersons. The aim of 80% of the videos was to inform laypeople and 14% to inform professionals only. The content discussed the most (59.3%) was the production stages of NGs. The mean CS and GQS score of the videos were 2.06 ± 1.35 (poor) and 1.71 ± 0.88 (generally poor), respectively. A positive correlation was found between the CS and GQS scores (r = 0.447). YouTube videos were found to be poor in terms of both content and quality. Since NGs for treating bruxism will always be a trending topic for patients on social media, the content of YouTube videos should be checked and enriched by professionals so that patients can access accurate information, especially about NGs obtained over the counter.

The efficacy of hyaluronic acid in postextraction sockets of impacted third molars: A pilot study

OBJECTIVE

This study aims to evaluate the effectiveness of local hyaluronic acid (HA) administration to surgically remove impacted third molar sockets and measure pain, swelling, and trismus.

MATERIALS AND METHODS

The study included a total of 25 healthy patients aged 18-29 years with asymptomatic bilaterally impacted lower third molars. All cases have been performed under local anesthesia. In the study group, 0.8% HA (Gengigel®) was applied in the postextraction sockets of the right third molars and in the control group nothing was applied to the extraction sockets of the left third molars. Postoperative pain, trismus, and swelling were evaluated on the 1st, 3rd, and 7th postoperative days.

RESULTS

No difference was determined between groups in facial swelling and maximum mouth opening. However, the amount of pain significantly reduced in HA groups according to visual analog scale (P = 0.001).

CONCLUSION

The results of this study showed that HA can produce an analgesic action in postextraction sockets after surgical removal of impacted teeth and therefore it has a clinical benefit to reduce usage of nonsteroidal anti-inflammatory drugs after dentoalveolar surgery.

An evaluation of effects of platelet-rich-fibrin on postoperative morbidities after lower third molar surgery

OBJECTIVES

The aim of the present study was to assess whether the use of platelet-rich fibrin (PRF) decreased the pain, swelling, and trismus levels of postoperative third molar surgery.

MATERIALS AND METHODS

In a double-blinded, split-mouth randomized study, thirty patients (6 male/24 female, mean age 20.32 years) with bilateral symmetric impacted third molars were enrolled in this study to receive surgery. The PRF mass was randomly placed in one of the extraction sockets, whereas the other socket was left without treatment. The outcome variables were pain, maximum mouth opening (trismus), swelling (edema), and the presence of dry socket which were measured using a 10-point visual analog scale, manual calipers, and 3dMD facial imaging system which was used for the 1st time in the third molar surgery.

RESULTS

Statistical analyses revealed that there were no significant differences between the control and study groups regarding postoperative pain, swelling, and trismus (P > 0.05).

CONCLUSION

The results of this study suggest that PRF was not observed to have a positive effect on postoperative discomfort, so even though, PRF is presumed to have positive effects on healing and recovery processes.

Three-Year Clinical and Radiographic Implant Follow-up in Sinus-Lifted Maxilla With Lateral Window Technique

INTRODUCTION

The aim of this study was to evaluate retrospectively the 3-year outcome of implants placed in augmented maxillary sinuses with minimal residual alveolar bone heights (≤3 mm).

MATERIALS AND METHOD

A total of 28 sinus floors were augmented with xenograft, and 58 implants were placed. The outcome measures were implant success based on implant stability and the absence of periimplantitis, and marginal and apical bone resorption on periapical radiograph and prosthesis survival.

RESULTS

Fifty-seven of 58 implants with their prostheses remained functional with a success rate of 98.28%. None of the implants showed any signs of mobility or periimplantitis. Both apical and cervical bone resorption around the implants were highest by the end of the first year.

CONCLUSIONS

The success rate of the implants placed with staged approach in augmented maxillary sinuses with the residual alveolar bone height of ≤3 mm was high in a 3-year term. Bio-Oss is an acceptable substitute autogenous bone and can be used as an augmentation material during the maxillary sinus lift procedure.

Effects of Ankaferd BloodStopper on bone healing in an ovariectomized osteoporotic rat model

Bone defects resulting from oncological surgical resections, congenital facial anomalies, trauma or infection represent a significant and common clinical problem. The present study aimed to evaluate the effects of a commercially-available medicinal plant extract product, Ankaferd BloodStopper (ABS), on bone healing. The present study was performed on 24 female ovariectomized (OVX) rats. A defect on each rat calvarium was created using a trephine burr prior to the rats being divided into two groups. Defects were grafted with a gelatin sponge soaked with normal saline (control group) or plant extract (experimental group). Half of the animals were sacrificed after 2 weeks and the others after 4 weeks. In the control group, the defects were not filled with regenerated bone. By contrast, in the experimental group, all defect areas had an increased amount of regenerated bone and connective tissue. Osteoblastic activity appeared to be greater in the experimental group however, osteoclastic activity was observed to be higher in the control group. At 2 and 4 weeks, there was a significant difference in the amount of newly regenerated bone observed in the experimental group compared with the control group (P<0.05). Therefore, the results of the present study indicated that local ABS application had a positive effect on bone healing in the OVX rat model.

Effect of caffeic acid phenethyl ester on bone formation in the expanded inter-premaxillary suture

BACKGROUND

Narrow maxilla is a common problem in orthodontics and dentofacial orthopedics. To solve this problem, a procedure called rapid maxillary expansion (RME) has been used. However, relapse tendency is a major problem of RME. Although relapse tendency is not clearly understood, various treatment procedures and new applications have been investigated. The present study aimed to investigate the possible effectiveness of caffeic acid phenethyl ester (CAPE) on new bone formation in rat midpalatal suture after RME.

MATERIALS AND METHODS

Twenty male Sprague Dawley rats were used in this study. The animals were randomly divided into two groups as control and CAPE group. In the CAPE group, CAPE was administered systemically via intraperitoneal injection. RME procedure was performed on all animals. For this purpose, the springs were placed on the maxillary incisors of rats and activated for 5 days. After then, the springs were removed and replaced with short lengths of rectangular retaining wire for consolidation period of 15 days. At the end of the study, histomorphometric analysis was carried out to assess new bone formation.

RESULTS

New bone formation was significantly greater in the CAPE group than the control group (P<0.05). CAPE enhances new bone formation in midpalatal suture after RME.

CONCLUSION

These results show that CAPE may decrease the time needed for retention.

Mandibular bone mineral density in patients with Behçet's disease

OBJECTIVES

Behçet's disease (BD) is a chronic, recurring vasculitis of unknown etiology. Patients with BD may use a lot of medications associated with the clinical symptoms. Drugs that are used in the treatment of BD may cause bone loss. The aims of the current study were to compare the bone mineral density (BMD) values between BD and healthy volunteers and describe the effect of disease duration on mandibular BMD.

MATERIALS AND METHODS

The study comprised 30 healthy volunteers (15 males and 15 females, mean age 35.50±6.80 years) and 45 patients with BD (24 males and 21 females, mean age 38.93±8.93 years). The BD group was subdivided according to disease duration (0-5, 6-10, and >10 years). The BMD value of the mandibular body was determined by the dual energy X-ray absorptiometry technique.

RESULTS

The mean mandibular body BMD values were 1.294±0.21 g/cm(2) in the control group and 1.216±0.22 g/cm(2) in the BD patients, although there was no statistically significant difference. The BMD was observed to decrease with increased disease duration but not to a statistically significant degree.

CONCLUSION

The results of this study showed that although the BMD value decreased as the duration of the disease increased, no statistically significant difference was found between the BD patients and the healthy control group.

Comparison of a new flap design with the routinely used triangular flap design in third molar surgery

The aim of this study is to introduce a new flap design in the surgical removal of impacted mandibular third molars - a lingually based triangular flap - and to compare this flap design with the routinely used triangular flap. This randomized, prospective, split-mouth study involved 22 patients with impacted bilateral mandibular third molars that were symmetrically positioned, mesially angulated, and retained in bone. The impacted teeth were removed in two sessions, using two different flap designs: the new alternative flap and the traditional triangular flap. Postoperative complications (pain, swelling, trismus, alveolar osteitis, and wound dehiscence) were recorded on days 2, 7, 14, and 21. The data obtained were analysed using the χ(2) test, the Mann-Whitney U-test, and Pearson's correlation. In terms of the severity of postoperative facial swelling and trismus, there were no statistically significant differences between the flap designs (P>0.05). The alternative flap exhibited higher pain scores at 12h post-surgery (P<0.05). In addition, the alternative flap group exhibited less wound dehiscence, although this was not statistically significant. Moreover, all wound dehiscence in this group occurred on sound bone. In conclusion, these results show that this new flap design is preferable to the routinely used flap for impacted third molar surgery.
