BACKGROUND
The complex presentation, associated co-morbidities and multi-disciplinary requirements dictate the requirement for in-depth knowledge in order to effectively manage patients with cleft lip and palate (CLP). We aimed to develop a validated questionnaire for cleft lip and palate knowledge assessment and to evaluate the knowledge of cleft lip and palate among a group of recently-graduated dentists.
MATERIALS AND METHODS
A multiple-site, cross-sectional questionnaire-based study was conducted. The study population included recently graduated dentists involved in a dental internship program. A bespoke questionnaire was developed and validated, with internal consistency assessed using Cronbach's alpha and factor analysis performed. A 47-item prototype was distilled into a 15-item questionnaire. This was distributed to the participants with a response rate of 67% obtained.
RESULTS
The overall proportion of correct responses among dental interns was moderate (73%). The best results were found in relation to CLP treatment including the effect of unfavorable surgical outcomes on speech (89.5%) and the impact of CLP on the occlusion (87.6%). The lowest rate of correct responses (26.7%) was identified in relation to the association between CLP and smoking.
CONCLUSION
A validated CLP questionnaire was developed, permitting evaluation of the knowledge of cleft lip and palate and its management among recently graduated dentists. There is limited appreciation among dental interns of the risk factors for CLP as well as post-surgical complications. Given that general dentists are often the gatekeepers for the management of patients with cleft lip and palate, it is important that the findings of this survey are used to inform the curriculum and teaching of cleft lip and palate.

Observational Study
OBJECTIVE
The aging of the occlusion and tooth wears influence the smile design This study aimed at evaluating the aging changes of maxillary anterior teeth in nontreated subjects.
METHODS
The sample comprised dental models of 23 subjects (13 male, 10 female) with normal occlusions, taken at 13 (T1), 17 (T2) and 61 (T3) years of age. The following variables were measured in the maxillary anterior teeth using digital dental models: crown width/height proportion, anterior view width, crown angulation, gingival and incisal steps between central/lateral incisors and central incisors/canines. Interphase comparisons were evaluated using repeated measures analysis of variance followed by Tukey tests or Friedman tests. Sexual differences were evaluated using t tests (P < 0.05).
RESULTS
From 13 to 61 years of age, a decrease of crown width/height proportion (P = 0.008 and P = < 0.001, for the lateral incisor and canines, respectively) and mesiodistal angulation (P = < 0.001, P = 0.001 and P = 0.025 for the central incisor, lateral incisor and canines, respectively) of the maxillary anterior teeth were observed. The steps of the gingival margin and the incisal steps decreased with aging.
CONCLUSIONS
From adolescence to late adulthood, untreated individuals with normal occlusions demonstrated changes in the maxillary anterior teeth that may impair the smile esthetics and attractiveness.

UNLABELLED
Cystic Fibrosis (CF) is an autosomal recessive disease characterized by the production of thick and viscous mucus progressively affecting various organs and systems, with recurrent respiratory infections. The aim of this study was to learn about the oral health characteristics in CF patients.
METHODOLOGY
Data, such as sociodemographic, general and oral health, were collected from the medical records of CF patients aged 0 to 18 years old. The number of patients with tooth decay, prevalence of developmental defects of enamel (DDE), classification of dental occlusion, sialometry, salivary pH and oral microbial profile and respiratory secretions evaluations were recorded.
RESULTS
Most patients had pancreatic insufficiency (84.2%), malnutrition (60%), respiratory problems (75.4%) and genotyping of the F508del (66.7%). Regarding the medications used, 96.5% used vitamins and electrolyte replacement, 84,02% used pancreatic enzymes, 64.9% used dornase alfa and 47% were using antibiotics. The percentage of patients with tooth decay was 19.3%, 47% had DDE, low salivary flow and basic salivary pH. The most prevalent microorganisms found on tongue biofilm and respiratory secretions were and PA. There was a positive association between the presence of bacteria and fungi found on both the tongue and respiratory secretions. The presence of fungi on the tongue biofilm was significantly associated with the use of antibiotics.
CONCLUSIONS
These findings underscore the importance of dentists focusing on prevention and on the specific needs of the patient as well.

How to ensure dental stability in new positions and reduce the likelihood of relapse is a major clinical concern in the orthodontic field. Occlusal contacts between arches may affect the transmission of masticatory forces, thereby influencing the biological response of the periodontal and the oromandibular system. Occlusion factors that may influence the stability after orthodontic tooth movement (OTM) remain largely unknown. Hence, this research was conducted in order to investigate the influence of different occlusal contact patterns on tooth stability and oromandibular system including the masseter muscle and the temporomandibular joint following OTM. By modifying the occlusal surfaces, in vivo animal study models with distinct occlusal patterns corresponding to clinical circumstances were established. The relapse distance of teeth and the level of inflammatory factors in the gingival cervical fluid were analyzed. We also closely observed the histological remodeling of periodontal tissue, masseter tissue, and joint tissue after one week of relapse. Moreover, genes expression in the alveolar bone was analyzed to illustrate the potential biological mechanisms of relapse under the influence of different occlusal contact patterns following OTM. Different occlusal contact patterns after OTM in rats were established. The intercuspation contact between cusp and fossa group exhibited the lowest level of relapse movement, inflammatory factors and osteoclast activity (P < 0.05). On the other hand, groups with interferences or inadequate contacts exhibited more relapse movement, and tend to promote inflammation of periodontal tissue and activate bone resorption (P < 0.05). Adequate occlusal contacts without interference may enhance tooth stability and reduce the likelihood of relapse. After active orthodontic treatment, necessary occlusal adjustment should be made to achieve the desired intercuspation contact relationship and ensure adequate contact between the arches. The elimination of occlusal interferences is crucial to achieving optimal stability and promoting overall healthy condition of the oromandibular system.

Review
Clinical problem solving evolves in parallel with advances in technology and discoveries in the medical field. However, it always reverts to basic cognitive processes involved in critical thinking, such as hypothetical-deductive reasoning, pattern recognition, and compilation models. When dealing with cases of acute abdominal pain, clinicians should employ all available tools that allow them to rapidly refine their analysis for a definitive diagnosis. Therefore, we propose a standardized method for the quick assessment of abdominopelvic computed tomography as a supplement to the traditional clinical reasoning process. This narrative review explores the cognitive basis of errors in reading imaging. It explains the practical use of attenuation values, contrast phases, and windowing for non-radiologists and details a multistep protocol for finding radiological cues during CT reading and interpretation. This systematic approach describes the salient features and technical tools needed to ascertain the causality between clinical patterns and abdominopelvic changes visible on CT scans from a surgeon's perspective. It comprises 16 sections that should be read successively and that cover the entire abdominopelvic region. Each section details specific radiological signs and provides clear explanations for targeted searches, as well as anatomical and technical hints. Reliance on imaging in clinical problem solving does not make a decision dichotomous nor does it guarantee success in diagnostic endeavors. However, it contributes exact information for supporting the clinical assessments even in the most subtle and intricate conditions.

INTRODUCTION
Dental implantation has emerged as an efficient substitute for missing teeth, which is essential for restoring oral function and aesthetics. Compared to traditional denture repair approaches, dental implants offer better stability and sustainability. The position, angle, and depth of dental implants are crucial factors for their long-term success and necessitate high-precision operation and technical support.
METHOD
We propose an integrated dual-arm high-precision oral implant surgery navigation positioning system and a corresponding control strategy. Compared with traditional implant robots, the integrated dual-arm design greatly shortens the preparation time before surgery and simplifies the operation process. We propose a novel control flow and module for the proposed structure, including an Occluded Target Tracking Module (OTTM) for occlusion tracking, a Planting Plan Development Module (PPDM) for generating implant plans, and a Path Formulation Module (PFM) for controlling the movement path of the two robot arms.
RESULT
Under the coordinated control of the aforementioned modules, the robot achieved excellent accuracy in clinical trials. The average angular error and entry point error for five patients who underwent implant surgery using the proposed robot were 2.1° and 0.39 mm, respectively.
CONCLUSION
In essence, our study introduces an integrated dual-arm high-precision navigation system for oral implant surgery, resolving issues like lengthy preoperative preparation and static surgical planning. Clinical results confirm its efficacy, emphasizing its accuracy and precision in guiding oral implant procedures.

AIM
This study examines the effects of juvenile idiopathic arthritis (JIA) on the oral health and detectability of inflammatory biomarkers IL-17, tumour necrosis factor-alpha (TNF-α) and total antioxidant status (TAS) in the saliva of children with JIA.
PATIENTS AND METHODS
This study included 117 participants (39 patients with JIA and 78 systemically healthy subjects aged 8-12 years). Demographic data, responses to an oral health-related questionnaire, saliva samples, periodontal parameters [plaque index (PI), gingival index (GI) and bleeding on probing (BOP)] and dental recordings [facial profile (FP) and dental occlusion relationship (DOR)] were obtained. Enzyme-linked immunosorbent assays were used to determine the levels of salivary IL-17, TNF-α and TAS.
RESULTS
The Caries Assessment Spectrum and Treatment (CAST) index, FP and DOR distributions did not change between groups (P > 0.05). JIA patients had more temporomandibular joint (TMJ) discomfort than gingivitis patients and healthy subjects (P < 0.05). JIA patients had greater salivary IL-17 levels than healthy subjects (P < 0.05). The healthy group's TAS was higher than that of the JIA and gingivitis groups (P < 0.05). Saliva TNF-α levels were similar between groups (P > 0.05). PI, GI, BOP and TNF-α were positively associated with salivary IL-17 (P < 0.001).
CONCLUSION
Elevated salivary IL-17 and TAS levels could be used as biological markers for discriminating the clinical health status of children with JIA and gingivitis.

Journal of Dentistry Jul 2024This study evaluated the reliability of a face scanner in measuring the vertical dimension of occlusion (VDO).
OBJECTIVE
This study evaluated the reliability of a face scanner in measuring the vertical dimension of occlusion (VDO).
METHODS
Fully dentate volunteers (n = 20; mean-age = 30.0 ± 10.7 years) were recruited. Clinical facial measurements were obtained using a digital caliper and a face scanner (Obiscanner, Fifthingenium, Italy). The scans were imported into a mesh-processing software, and the distances were measured digitally. Measurements were obtained for each participant with the jaws positioned in maximal intercuspation (MI) and with increased vertical distances of 2, 4, and 6 mm. Vertical and horizontal measures were obtained using facial anatomical landmarks: Glabella (GL), Pronasale (PrN), Subnasale (SbN), inferior border of the right and left Alare, Labiale superius (Ls), right and left Cheilion (Ch), Soft Pogonion (SPg), right and left Tragus of the ear (Tr), for all selected vertical positions. Data analysis included intra-class correlation coefficient (ICC), pairwise comparison tests, Bland-Altman plots, and Passing-Bablok regression.
RESULTS
120 VDO measurements (clinical=60, digital=60) were recorded by two independent evaluators. Mean differences between digital and clinical measurements ranged from 0.054 ± 0.14 mm to 0.203 ± 0.13 mm. All parameters were strongly correlated (r > 0.93; p < 0.001). ICC estimates revealed excellent reliability, and the measuring procedure yielded the same results on repeated trials irrespective of the raters and measurement methods. Bland-Altman plots revealed a difference, between digital and clinical measurements, of 1.7 % for the vertical measurements. Regression analysis revealed no significant proportional difference between the two methods, so both can be used interchangeably.
CONCLUSIONS
The findings of this study demonstrate that VDO can be measured accurately from face scans using 3D mesh-processing software and that even small changes in the VDO could be detected using the digital methods.
CLINICAL SIGNIFICANCE
Findings provide evidence about the reliability of a digital method for jaw relation registrations and may be applied towards incorporating this method into clinical workflows for computer-aided-design/ computer-assisted-manufacturing (CAD-CAM) dentures.

This article describes a chairside technique of addition of teeth to a patient's existing acrylic partial denture at the extraction appointment without the need for dental laboratory intervention. This maintains aesthetics, function, phonation, biologic integrity, patient confidence, and psychological well-being. An immediate denture is any fixed or removable dental prosthesis fabricated for placement immediately after the removal of a natural tooth/teeth [1,2]. Immediate dentures have many advantages over conventional dentures including conservation of patient's integrity, aesthetics, functionality, soft tissue support and occlusion [2-4]. Immediate dentures require several visits with associated costs and the patient has a period of adjustment to the new prosthesis. This clinical report describes a simple and fast technique of chairside immediate tooth addition to an existing denture avoiding some of these issues.

We present the clinical course of a 9-year-old female patient with Bloch-Sulzberger syndrome and severe neurological deficit that met the major (classic cutaneous signs) and minor (dental anomalies and retinal pathology) diagnostic criteria of Landy and Donnai. Longitudinal multidisciplinary follow-up was carried out from birth to adulthood. Neurological involvement was assessed with electroencephalographic (EEG) and neuroimaging tests at different times during the patient's life. Cranio-maxillofacial involvement was evaluated using lateral skeletal facial and cephalometric analyses. The right and left facial widths were measured through frontal face analysis and using the vertical zygomatic-midline distance. Oral rehabilitation was performed through orthodontic treatment and major dental reconstruction using composite resins. This treatment aimed to improve the occlusion and masticatory function, relieve the transversal compression of the maxilla, and reconstruct the fractured teeth. We believe that, due to significant neurological and cognitive impairment, orthognathic surgery was not the best option for restoring function and improving oral health-related quality of life.
