Musculoskeletal problems have become a significant issue in the profession of dentistry. There are currently no recommended effective disease-preventing and modifying remedies. High prevalence rates for musculoskeletal disorders (MSDs) among dentists have been reported in the literature. Complementary and alternative medicine can be helpful in managing and preventing the MSDs. The purpose of this study was to determine if dentists in the western part of India are using complementary and alternative medicine therapies for MSDs, and also to find if those who use complementary and alternative medicine therapies have greater job/career satisfaction compared to conventional therapy (CT) users. Dentists of western India registered under the Dental Council of India (N = 2166) were recruited for the study. Data were analyzed using univariate and bivariate analyses and logistic regression. A response rate of 73% (n = 1581) was obtained, of which 79% (n = 1249) was suffering from MSDs. The use of complementary and alternative medicine or CT was reported by 90% (n = 1124) of dentists with MSDs. Dentists using complementary and alternative medicine reported greater health (P < 0.001) and carrier satisfaction (P < 0.001) and were able to work as many hours they wanted (P < 0.001) compared to CT users. Complementary and alternative medicine therapies may improve the quality of life and enhance job satisfaction for a dentist who suffers from MSDs.

Acupuncture (針灸 Zhēn Jiǔ) (‘acus’ (needle) + ‘punctura’ (to puncture)) is the stimulation of specific points along the skin of the body involving various methods such as penetration by thin needles or the application of heat, pressure, or laser light. Acupuncture (針灸 Zhēn Jiǔ) aims to treat a range of medical and dental ailments, though is most commonly used for pain relief. This article reviews about the various possible roles of acupuncture (針灸 Zhēn Jiǔ) in clinical dental practice. Acupuncture (針灸 Zhēn Jiǔ) has potential in supplementing conventional treatment procedures by its diverse applicability outreach. Role of acupuncture (針灸 Zhēn Jiǔ) in dental practice has been well supported by clinical trials. Its role in alleviating facial pain, pre-operative and post-operative dental pain has led to its widespread application. Its role as sole analgesic for treatment procedure has to be tested. It's It is a thought that acupuncture (針灸 Zhēn Jiǔ) may prove an indispensible supplement to conventional treatment modalities and more of clinical trials and studies are required to prove the efficacy. Acupuncture (針灸 Zhēn Jiǔ) is not a miracle cure and is not going to replace the drill. However, the technique can be a supplement to conventional treatments in TMDs, facial pain, pain management Sjoegrens syndrome, and in phobias and anxiety. The application and use of Acupuncture (針灸 Zhēn Jiǔ) comes with some side effects. Proper training needs to be obtained before commencement of any procedure related to acupuncture (針灸 Zhēn Jiǔ). Various training programs are offered to train clinical practitioners the apt method to use acupuncture (針灸 Zhēn Jiǔ).

Introduction: There are numerous chances for pulpal irritation during the placement of a crown on a tooth. This study’s goal was to find and examine the variables that influence the prevalence of routine root canal therapy after the teeth were restored with full coverage crowns. Methods: The hospital records were retrospectively evaluated from 2000 to 2010 for a decade. The demographics as well as the various variables that caused for the intervention with the root canal therapy for the teeth with the full crowns were evaluated. The values were compared for the significance. Results: The total number of the teeth that were finalized in the study was 4308. Of the total teeth that were treated with full coverage crowns, 50% were metal ceramic, 42% were full ceramic, and 9% were full metal crowns. After 10 years, possibility that every tooth with a crown would survive was 91%. The most frequent adverse incident was the intervention with the RCT. Metal ceramic crowns had poor survival rates and needed the maximum intervention. Younger age-group had least survival rate than the older age-groups. Conclusions: Endodontic therapy is unlikely to be necessary after crown installation. As the patient’s age declines and all-ceramic or PFM crowns are used, this risk rises.

BACKGROUND: Advances in digital dentistry lead to use of three-dimensional (3D) printed resin denture teeth. Fracture toughness of these teeth must be assessed. OBJECTIVE: This study aimed to compare the chipping and indirect tensile fracture resistance of denture teeth fabricated by 3D printing technique with traditionally fabricated resin denture teeth. METHOD: Four groups (Gr) were made (n= 50/group): Gr-1 3D printed denture teeth (denture teeth; Formlabs Inc., Somerville, MA, USA), Gr-2 SR-Orthosit-PE (Ivoclar Vivadent AG), Gr-3 Portrait IPN (Dentsply Sirona), Gr-4 Pala Premium 8 (Heraeus Kulzer GmbH). Stereolithography 3D printing was used to create the methacrylate-based photopolymerized resin teeth models and remaining group teeth were collected commercially. A 1 mm/min chipping and indirect tensile fracture speed tests were carried out till fracture occurred. The data so obtained were statistically analysed using one-way analysis of variance with Tukey’s honestly significant difference multiple comparisons test (p< 0.05). At the end of the test, the fractured areas of the specimens were evaluated by the chief researcher to assess the fracture pattern of the teeth. RESULTS: The indirect tensile fracture values of the 3D printed teeth were more than that of Pala Premium-8 and SR-Orthosit-PE but it was lower than that of Portrait IPN teeth. In chipping test, buccal chipping of the loaded cusp was seen in 3D printed resin without distortion and in indirect tensile test in 3D printed resin teeth, line of fracture emerges near the loading point propagates from the inner incline of both cusps and extends cervically, unlike in other groups where first deformation occurs then fracture. CONCLUSION: Prosthetic teeth fabricated by the 3D printing technique using printable resin material provide adequate fracture resistance as denture teeth.

Introduction: The best treatment for the deeply carious tooth that cannot be restored is by the root canal therapy. This method has saved many patients from the loss of tooth. The common practice is either to deliver a full crown or close the access cavity with restoration. Hence in this study, the clinical longevity of the routine practice is tested for by analyzing the fracture toughness and the survival of the teeth that were restored endodontically with various materials. Materials and Methods: The hospital records were retrospectively evaluated from 2000 to 2010 for a decade. The demographics as well as the survival and the failure rates noted and compared for the various types of the restorations. The number of the walls of the teeth was also compared. Results: Thousand teeth were considered in the study. Less than 7% of teeth had coronal fractures. Of the 93% teeth that had survived, the most common restoration was Individual post (+ crown) followed by GIC, amalgams, and crowns. The mean survival of the crown+ bridge & gold restoration was highest. The mean survival was 10 ± 2 years for the restored teeth without any fractures at the coronal level. The failure was greatest for the GIC followed by amalgam, and the variations when compared with other restorations were significant. There was no significant difference for the number of the walls on the crown; however, the number of walls present was proportional to the survival rate. Conclusion: The teeth that were covered with a crown were comparatively fracture resistant and had a better survival rate compared to other restorations. GIC showed highest fracture, and the post core with crown had the best survival. Restoration of the lost crown architecture and the reinforcement are the best methods that can be followed for the survivals.
