Objective assessment of intra-oral suturing for certification of competency.

INTRODUCTION: Suturing is an essential skill for dental surgeons, yet there is limited evidence for objective measures of competence in this field, which can be applied to licensing or certification processes for dental surgeons to ensure patient safety. METHODS: In an objective structured clinical examination (OSCE), participants placed two simple interrupted sutures across a lower molar socket in different suturing environments: [A] commercial simulator, [B] suturing sponge mounted in a 3D printed model, [C] suturing sponge and [D] pig's jaw. Simulators [A] and [B] were mounted into phantom heads in dental chairs, and [C] and [D] were placed on bench tops. Performance indicators, overall task success, quality of sutures placed, length of suture remaining and time taken, were analysed against participants' characteristics such as previous suturing experience. RESULTS: Participants (n = 38) took significantly longer to successfully complete the sutures on models mounted in a phantom head. Time points at which each model differentiated between competent (n = 11) and novice (n = 27) participants were as follows: model A (3:26 min), B (2:41), C (2:05) and D (2:06). Model A showed a significant association between task completion and previous suturing experience (p = .006). CONCLUSION: Suturing simulators can be used to objectively differentiate between novice and competent dental surgeons. Model A demonstrated construct validity, as it reliably identified competence using time and task completion as objectively measurable parameters. Utilising model A, the candidate of unknown ability could be identified as appropriately skilled at intra-oral suturing. To ensure patient safety, further research is needed to identify other objective measures of competence in simulation environments.

Periodontal Disease, Dental Implants, Extractions and Medications Related to Osteonecrosis of the Jaws.

Patients taking bisphosphonates and other anti-resorptive drugs are likely to attend general dental practice. The term 'bisphosphonate'is often immediately associated with osteonecrosis of the jaws (ONJ). Risk assessment and subsequent management of these patients should be carried out taking into account all the risk factors associated with ONJ. The introduction of newer drugs, also shown to be associated with ONJ, demands increased awareness of general dental practitioners about these medications. CPD/CLINICAL RELEVANCE: This paper provides an update on medication-related ONJ and considers the effects of anti-resorptive drugs on the management of patients needing exodontia, treatment for periodontal disease and dental implant placement.

Treatment of a Crohn's disease-related cutaneous facial lesion with topical tacrolimus.

We report a case of an orofacial lesion in Crohn's disease successfully treated with tacrolimus ointment. A 22-year-old woman with Crohn's disease presented with a discharging lesion on the right side of her face. Intraorally, there was a resultant loss of the sulcal depth. She reported a 1-year history of variable right-sided facial swelling for which she had undergone extraoral incision and drainage, resulting in localized paresthesia and nonhealing of the incision site. Following exclusion tests, a treatment of twice-daily extraoral application of tacrolimus 0.1% ointment was commenced. Upon review, the lesion had reduced in size, with minimal discharge. Further improvement over 12 months of tacrolimus use resulted in a satisfactory cosmetic result as well as resolution of the intraoral features and reestablishment of the full sulcal depth. This case illustrates the successful use of topical tacrolimus to treat a cutaneous manifestation of Crohn's disease.
