RESUMEN
BACKGROUND: Qualitative sensory testing (QualST) is a simple, standardised, chairside method for evaluating somatosensory function; however, testing focuses on detection of cold, touch and pain with no recognition of perceptions of pleasantness and unpleasantness. OBJECTIVES: The study aimed to utilise the stimuli in QualST, with the addition of a soft brush, to investigate stimulus-evoked perceptions of pleasantness and unpleasantness on the facial skin and if any side-to-side differences. Additional aims were to determine the inter- and intra-rater reliability using the modified QualST protocol and in the side-to-side differences. METHODS: Thirty healthy adult female participants underwent three sessions of sensitivity testing as per the modified QualST protocol. Stimuli were applied bilaterally to the facial skin, and participants provided separate yes/no responses for presence of stimulus-evoked pleasantness, unpleasantness and/or differences between sides. RESULTS: The stimuli were able to evoke sensations of pleasantness and unpleasantness with little differences in responses between the Q-tip and goat hair brush for the perceptions. Side-to-side differences in evoked perceptions were observed and greatest, when evaluating for pinprick-evoked unpleasantness (range between sessions = 18-19 participants). Acceptable percentage (≥90%) and excellent Cohen's Kappa (≥0.762) inter- and intra-rater agreements were identified for one or more positive responses for each stimulus modality and the targeted perception. CONCLUSION: The modified QualST protocol provides a simple, reproducible method for the investigation of perceptions of pleasantness and unpleasantness, with readily accessible instrumentation to dental professionals and allowing for a more holistic approach in somatosensory testing.

OBJECTIVES: To evaluate variation in treatment plans and pathological findings related to maxillary second and third molars based on panoramic (PAN) images and cone beam CT (CBCT) among Danish and Dutch oral and maxillofacial surgeons. STUDY DESIGN: This web-based "paper" clinic contained 10 cases of impacted maxillary third molars comprising clinical information, PAN, and CBCT. Treatment plan and pathological findings were established based on clinical information and PAN, thereafter, based on CBCT by 28 surgeons. Options for treatment plan for third molars were no treatment, or tooth removal. Options for treatment plan for second molars were no treatment, tooth removal, or endodontic and/or filling therapy. The surgeons assessed external root resorption, marginal bone loss, and follicular space. RESULTS: A change in treatment plan between PAN and CBCT was registered between 0% and 43% of the surgeons among the cases. The surgeons did not agree completely on the treatment plan in any of the cases. Variation was present among the surgeons evaluating pathological findings. In several cases, severity of root resorption was rated worse in CBCT than in PAN. CONCLUSIONS: Variation in treatment plan and pathological findings was observed among surgeons. No correlation between change in pathological findings and change in treatment plan was found.
RESUMEN
Objectives: Dentofacial deformity following juvenile idiopathic arthritis with temporomandibular joint involvement is associated with functional, aesthetic, and psychosocial impairment. Surgical treatment may involve combinations of orthognathic surgery. The aims of this retrospective study were to assess orofacial symptoms, functional and aesthetic status, and stability after orthognathic surgery. Material and Methods: Nineteen patients with juvenile idiopathic arthritis of the temporomandibular joint (TMJ) and dentofacial deformities were included. All patients were treated with combinations of bilateral sagittal split osteotomy, Le Fort I and/or genioplasty, between September 10, 2007 and October 17, 2017. Analysis of patient symptoms and clinical registrations, and frontal/lateral cephalograms was performed pre- and postoperative and long-term (mean: 3.8 and 2.6 years, respectively). Results: Patients experienced no changes in orofacial symptoms or TMJ function, and stable normalisation of horizontal and vertical incisal relations at long-term (horizontal overbite; vertical overbite: P < 0.05). Mandibular lengthening was achieved postoperatively (from mean 79.7 to 87.2 mm; P = 0.004) and was stable. Sella-nasion to A point (SNA) and sella-nasion to B point (SNB) angles increased postoperatively (SNA, mean 79.9° to 82.8°; P = 0.022 and SNB, mean 73.9° to 77.8°; P = 0.003), however, largely reverted to preoperative status at long-term. Conclusions: Orthognathic surgery normalized incisal relations while providing stable mandibular lengthening without long-term deterioration of temporomandibular joint function or orofacial symptoms. No long-term effect on jaw advancements was observed.
