Case Difficulty Assessment

Abstract Background A Case Difficulty Assessment Form was designed for use in endodontic curricula, and to assist practitioners with treatment planning, referral and recording. The aim of this study was to determine how endodontic case difficulty factors influence the operating time of single-visit nonsurgical endodontic treatments under general anesthesia. Methods Data on 198 single-visit endodontic treatments (80 anterior teeth, 43 premolars, and 75 molars) performed under general anesthesia by a specialized practitioner were obtained from 119 special needs patients (mean [SD] age = 30.7 [14.7] years). Total duration of operation was analyzed with relation to demographic and dental factors and American Association of Endodontists (AAE) Case Difficulty Assessment factors. Mann–Whitney U test, t-test, and Kruskal–Wallis test were used to assess relationships between operating time and confounding factors (p < 0.05). Results High difficulty cases required significantly longer time to complete operations than treatments of minimal-to-moderate difficulty regardless of tooth type (p < 0.05). Demographic factors of the patients rarely influenced operating time length. Among variables included in the AAE Case Difficulty Assessment Form, tooth position, crown morphology, root morphology, canal appearance, and periodontal condition were significantly associated with increased operating time (p < 0.05). Conclusions A higher level of case difficulty contributed to increased duration of endodontic treatment under general anesthesia indicating that Endodontic Case Difficulty Assessment Form is useful for predicting the duration of nonsurgical endodontic treatment. Among many factors, complicated anatomic features of the treated teeth increased case complexity and extended operating time.

Introduction: Laparoscopic inguinal hernia repair is a tension-free mesh repair that is based on pre-peritoneal approach of repair. It provides mechanical advantage to the surgeon, by being able to place a large piece of mesh and by using the natural force of the abdominal wall to disperse the intra-abdominal pressure over a large area to support the mesh. This retrospective study is aimed to study the demography of inguinal hernia and to compare operating time, complications and postoperative pain between patients undergoing Total Extrapritoneal (TEP) or Transabdominal Preperitoneal (TAPP) repair.Methods: A retrospective comparative study was conducted in patients with inguinal hernia who underwent laparoscopic repair by either TEP or TAPP, between April 2019 to July 2020 at Nobel Medical Collage Teaching Hospital, Biratnagar, Morang. Age, sex, type of hernia, duration of operation, post-operative complications, severity of pain and duration hospital stay were analyzed between two groups of patients undergoingsurgery by either TEP or TAPP.Results: One hundred and five patients underwent either TEP or TAPP during study period. There were 96 males and 9 females. There were 50 patients with right, 40 with left and 6 patients with bilateral inguinal hernia. Four patients had left sided irreducible inguinal hernia, 2 patients had bilateral recurrent inguinal hernia, 2 patients had right sided recurrent inguinal hernia and 1 patient had left sided recurrent inguinal hernia.There was significant difference in duration of operation (TEP 64.43min) / (TAPP 84.46min), p<0. 001. Total duration of hospital stay and postoperative pain were not significant between patients operated with TEPor TAPP. Accidental pneumoperitoneum was noticed in 8 cases, 10 cases of subcutaneous emphysema, 5 cases of seroma and 1 case of scrotal hematoma in TEP group. In TAPP group scrotal hematoma occurred in 4 cases and seroma in 5 cases which was not significantly different from TEP group.Conclusion: TAPP had significantly longer operating time as compared to TEP. However, there was no significant difference in post-operative pain and hospital stay in both group.

ABSTRACT Purpose The objective of this study was to compare postobturation flare-ups following single and two-visit endodontic treatment of molar teeth with periapical radiolucency. Materials and methods A total of 100 patients with asymptomatic molar teeth with periapical radiolucency were selected. They were randomly allocated into two groups. Fifty patients received complete endodontic treatment in one-visit. Fifty patients received treatment by debridement and instrumentation at the first visit followed by obturation at the second visit. Results 10% of patients had flare-ups in the single visit group and 8% of patients had flare-ups in the two-visit group. Number of visits did not affect the success of endodontic treatment (p > 0.05). Age, gender and tooth type had no effects on the occurrence of flare-ups regardless the number of visits (p > 0.05). Conclusion One-visit endodontic treatment was as successful as two-visit endodontic treatment as evaluated by rate of flareups in asymptomatic molar teeth with periapical radiolucency.

ABSTRACT Anterior crown fractures are common form of traumatic dental injuries that mainly affect the maxillary anterior teeth in children, teenagers as well as adult population. A trauma with accompanying fracture of anterior teeth is an agonizing experience for an individual requiring immediate attention, not only because of the physical disfigurement but also because of the psychological impact on the patient. Over time numerous techniques and materials have evolved for the restoration of the injured teeth, such as, resin composite with or without pin, orthodontic bands, resin crown, and ceramic crowns. Reattachment of fractured tooth fragments can provide good and long-lasting esthetics and function. Patient cooperation and understanding of the limitations of the treatment is important for good prognosis. This article reports management of complicated coronal tooth fracture treated by reattachment on tooth fragments on the palatal aspect and single visit nonsurgical endodontic treatment.

ABSTRACT Objective: To evaluate the accuracy of Invisalign technology in achieving predicted tooth positions with respect to tooth type and direction of tooth movement. Materials and Methods: The posttreatment models of 30 patients who had nonextraction Invisalign treatment were digitally superimposed on their corresponding virtual treatment plan models using best-fit surface-based registration. The differences between actual treatment outcome and predicted outcome were computed and tested for statistical significance for each tooth type in mesial-distal, facial-lingual, and occlusal-gingival directions, as well as for tip, torque, and rotation. Differences larger than 0.5 mm for linear measurements and 2° for angular measurements were considered clinically relevant. Results: Statistically significant differences (P &lt; .05) between predicted and achieved tooth positions were found for all teeth except maxillary lateral incisors, canines, and first premolars. In general, anterior teeth were positioned more occlusally than predicted, rotation of rounded teeth was incomplete, and movement of posterior teeth in all dimensions was not fully achieved. However, except for excess posttreatment facial crown torque of maxillary second molars, these differences were not large enough to be clinically relevant. Conclusions: Although Invisalign is generally able to achieve predicted tooth positions with high accuracy in nonextraction cases, some of the actual outcomes may differ from the predicted outcomes. Knowledge of dimensions in which the final tooth position is less consistent with the predicted position enables clinicians to build necessary compensations into the virtual treatment plan.

Abstract Background Work-related musculoskeletal disorders (WMSDs) affect a significant percentage of the neurosurgical workforce. The aim of the current questionnaire-based study was to examine the prevalence of WMSDs amongst neurosurgeons, identify risk factors, and study the views of neurosurgeons regarding ergonomics. Methods From June to August 2020, members of the “European Association of Neurosurgical Societies,” the “Neurosurgery Research Listserv,” and the “Latin American Federation of Neurosurgical Societies” were asked to complete an electronic questionnaire on the topics of WMSDs and ergonomics. Results A total of 409 neurosurgeons responded to the survey, with a 4.7 male to female ratio. Most of the surgeons worked in Europe (76.9%) in academic public hospitals. The vast majority of the participants (87.9%) had experienced WMSDs, mainly affecting the shoulder, neck, and back muscles. The most common operations performed by the participants were “Craniotomy for convexity/intrinsic tumors” (24.1%) and “Open lumbar basic spine” (24.1%). Neurosurgeons agreed that ergonomics is an underexposed area in the neurosurgical field (84.8%) and that more resources should be spend (87.3%) and training curricula changes should be made (78.3%) in order to alleviate the burden of WMSDs on neurosurgeons. Univariate analysis did not reveal any associations between the development of WMSDs and age, gender, tenure, average duration of operation, operating time per week, type of operation, and surgical approach. Conclusions The problem of WMSDs ought to be more closely addressed and managed by the neurosurgical community. More studies ought to be designed to investigate specific ergonomic parameters in order to formulate practice recommendations.

ABSTRACT Management of non vital teeth with open apices isa challenge to the dental practitioners. In this clinical scenario, it is difficult to maintain the obturating material confine within the root canal without encroaching into periapical area. These kinds of cases cannot be managed by conventional endodontic treatment, and treatment of such cases with calcium hydroxide may take longer time for apical closure. But with this new material called BIODENTINE (Septodont) same treatment can be done in single visit with predictable result. Hence this case report present the use ofbiodentine to form an apical plug in open apex followed by complete root canal obturation using thermoplasticized guttapercha.

Chewing Behaviour

Dental microwear texture analysis (DMTA) is widely used for diet inferences in extant and extinct vertebrates. Often, a reference tooth position is analysed in extant specimens, while isolated teeth are lumped together in fossil datasets. It is therefore important to test whether DMT is tooth position specific, and if so, what the causes for wear differences are. Here we present results from controlled feeding experiments with 72 guinea pigs, which either received fresh or dried natural plant diets of different phytolith content (lucerne, grass, bamboo), or pelleted diets with and without mineral abrasives (frequently encountered by herbivorous mammals in natural habitats). We test for gradients in dental microwear texture along the upper cheek tooth row. Regardless of abrasive content, pelleted diets display an increase in surface roughness along the tooth row, indicating that posterior tooth positions experience more wear compared to anterior teeth. Guinea pigs feedings on plants of low phytolith content and low abrasiveness (fresh and dry lucerne, fresh grass) show almost no DMT differences between tooth positions, while individuals feeding on more abrasive plants (dry grass, fresh and dry bamboo) show a gradient of decreasing surface roughness along the tooth row. We suggest that plant feeding involves continuous intake and comminution by grinding, resulting in posterior tooth positions mainly processing food already partly comminuted and moistened. Pelleted diets require crushing, which exerts higher loads, especially on posterior tooth positions, where bite forces are highest. These differences in chewing behaviour result in opposing wear gradients for plant versus pelleted diets.

In this study, 120 teeth having periradicular pathosis were treated with single visit root canal treatment and then obturated with either calcium hydroxide containing sealer or mineral trioxide aggregate based sealer. The healing of periradicular pathosis was examined at 3, 6, and 12 months by clinical and radiological evaluation. Collected data were analyzed with standard statistical methods by using SPSS version- 20. The results showed that at 3 and 6 months, the differences between calcium hydroxide containing sealer or mineral trioxide aggregate based sealer were not statistically significant. However, the healing capability of periapical radiolucency at 12 months between two groups was statistically significant (P=0.03). The final outcome of the clinical and radiological investigation showed successful results of 96.6% and 98.1% in calcium hydroxide and mineral trioxide aggregate group, respectively. In conclusion, both calcium hydroxide and mineral trioxide aggregate based sealers are almost equally effective in single visit root canal therapy for the management of periradicular pathosis.

Structure of the anterior teeth after endodontic treatment usually become weak because of the extensive loss of toothstructure. It causes a big problem to an endodontically treatment tooth when considering its restoration, examplereduced strength of the remaining tooth structure. Restoration that covers the tooth crown can be used if aesthetic andfunctional problems factors have been considered. However, composite resins are also often the treatment of choice forthe restoration of endodontically treated tooth. In this literature review, it will be discussed the selection of the properrestoration of the anterior teeth that have been endodontically treated.
