RESUMEN
The transposition of teeth is an infrequent dental abnormality characterized by the exchange of position between two adjacent teeth. This report presents a unique case of transposition involving the maxillary right canine and lateral incisor in a 20-year-old female patient. Clinical assessment and radiographic evaluation revealed the unconventional positioning of the affected teeth. Treatment planning necessitated collaborative efforts between orthodontic specialists to achieve optimal esthetic and functional outcomes. The patient underwent a comprehensive treatment regimen, including orthodontic alignment by distal drifting of the canine and mesial shifting of the lateral incisor. Subsequent long-term follow-ups confirmed stable occlusion and satisfactory esthetics in a time period of 18 months. This case underscores the significance of precise diagnosis and a multidisciplinary approach in managing intricate dental anomalies such as tooth transposition.
RESUMEN
Porcelain laminate veneers (PLV) offer a conservative aesthetic solution for interdental space closure. However, space is typically not distributed symmetrically, and the mesiodistal width of the restored teeth may increase unless multiple teeth are prepared for conventional PLV to maintain appropriate individual tooth proportion. Ceramic fragments can be suggested to close the space without modifying tooth size and dental proportion. This article presents two cases where interdental gaps were closed using lingually placed porcelain laminate (LPPL). All stages of the restorative procedures, including treatment planning, temporization, tooth preparation, and cementation of these delicate restorations, are detailed. Based on the results of these clinical reports, we regard the use of LPPL as a successful treatment option in selected cases, as evidenced by 2- and 6-year follow-ups. The Modified United State Public Health Criteria is reported.
RESUMEN
The pigmented lesions of the oral cavity may be endogenous or exogenous. Among the options for depigmenting these areas, laser therapy stands out for being a minimally invasive procedure. This study aims to report a clinical case of the gingival depigmentation technique using a high-power diode laser in the anterior maxillary region, for the ablation of the pigmented tissue to improve gingival aesthetics. The patient had an aesthetic complaint of the darkened aspect of the gingiva in the anterior maxillary portions. After local anesthesia, we started depigmentation with a high-power diode laser and performed ablation from the attached gingiva toward the free marginal gingiva. The patient returned after 30 and 180 days presenting healthy gingiva and absence of melanin repigmentation. Thus, we concluded that the diode laser was a good alternative for melanin depigmentation because it is a procedure with lower morbidity and satisfactory results.
RESUMEN
Minocycline, the synthetic derivative of the antibiotic tetracycline, has been used for a variety of medical treatments. One such use for minocycline is for acne vulgaris. Although widely used, minocycline has a common side effect of discoloration of tissues, including bone, skin, and mucosa. This case report presents a 19-year-old female patient with a history of long-term minocycline therapy for acne vulgaris who presented for periodontal esthetic crown lengthening. The initial exam revealed a blue-gray discoloration of the mucosa. Upon surgical exploration, it was discovered that the discoloration originated from the underlying alveolar bone with minimal gingival involvement. Surgical removal and recontouring of the bony exostoses revealed that the bone remained deeply stained. Although the discolored bone was not fully removed, the patient was able to obtain an acceptable esthetic result.
RESUMEN
BACKGROUND: Nasolabial fold (NLF) depression can affect the facial appearance of patients to some extent and increase their psychological burdens. In recent years, autologous fat grafting (AFG) combined with botulinum toxin A (BTX-A) injection (AFG + BTX-A injection) has been gradually applied in the treatment of patients with NLF depression. Although studies have been conducted on the efficacy and safety of AFG + BTX-A injection in treating NLF depression, the experimental design, observational indicators, and sample enrollment criteria vary remarkably, making it difficult to draw convincing and consistent conclusions. Thus, further relevant research is warranted. AIM: To assess the esthetic improvement, efficacy, and safety of AFG + BTX-A injections in patients with NLF depression. METHODS: This study included 60 patients with NLF depression who were treated in our hospital from February 2019 to April 2021. These patients were categorized into control (n = 30) and observation (n = 30) groups. The observation group received AFG + BTX-A injection, whereas the control group underwent AFG only. All patients were evaluated using the wrinkle severity rating scale (WSRS) and global aesthetic improvement scale. The compactness of facial contours, skin evaluation indexes, adverse reactions, and satisfaction of the two groups were evaluated 3 months postoperatively. RESULTS: The WSRS scores of the observation group at 1, 3, and 6 months postoperatively were lower than those of the control group (P < 0.05). Three months postoperatively, facial fine lines and pores showed obvious improvement and the skin index score was higher in the observation group than in the control group (P < 0.05). The compactness of facial contours was better in the observation group than in the control group (P < 0.05). In addition, no remarkable differences were noted in the incidence of postoperative adverse reactions such as facial stiffness, facial asymmetry, facial bruising, and facial concavity inequality (P > 0.05). CONCLUSION: AFG + BTX-A injection is a highly safe, cost-effective, effective, and long-lasting treatment for NLF depression with high esthetic value, which should be promoted in the future.

BACKGROUND/OBJECTIVE: A contemporary concept states that dental midline deviation towards the direction of facial flow line (FFL) can mask the compromised smile esthetics. This study aimed to identify a range of midline deviations that can be perceived towards or away from the FFL influencing smile esthetics. MATERIALS AND METHODS: A cross-sectional study was conducted using a frontal smile photograph of an adult female. The photograph was altered on Adobe Photoshop software into six different photographs by deviating the dental midlines towards and away from the FFL. A constant deviation of chin towards the left side was incorporated in all the photographs. Forty-three laypersons (LP) and dental professionals (DPs) evaluated those photographs. Independent t-test was used to compare the perception of dental midline deviation between LP and DPs. Simple linear regression was run to identify the factors associated with the scoring. RESULTS: A statistically significant difference was observed for picture two with 4 mm towards FFL in the perception of midline deviation between LP and DPs. LP could not perceive the midline deviations up to 4 mm while DPs were able to perceive deviations above 2 mm. The greater the age the better the scores were and female raters had a greater inclination towards poor scores. CONCLUSIONS: From 2 to 4 mm of midline deviation towards the FFL can be tolerated by LP and DPs. CLINICAL SIGNIFICANCE: These findings underscore the importance of considering facial symmetry in orthodontic and cosmetic dental treatments to optimize smile esthetics.
RESUMEN
AIM: The objective of the present study was to evaluate the influence of different adhesive strategies regarding shear bond strength (SBS) of provisional resin--based materials bonded to the enamel surface as well as on the enamel surface roughness. MATERIALS AND METHODS: Bovine incisors were randomly divided into six groups (n = 10) according to the adhesive strategy used: BRControl (bis-acrylic resin); Spot-etch+BR (spot-etch + bis-acrylic resin); Spot--etchSB2+BR (spot-etch + adhesive + bis-acrylic resin); Spot-etchZ350Flow+BR (spot-etch + flowable composite resin + bis-acrylic resin); SBU+BR (universal adhesive + bis-acrylic resin); Spot-etchSBMP+Z350 (spot-etch + adhesive + composite resin). The enamel surface roughness was determined by a surface profil-ometer. An SBS test was performed in a universal testing machine, and failure modes were classified under magnification. The SBS data were analyzed by one-way analysis of variance (ANOVA). A paired t test was used for enamel surface roughness intragroup comparisons, and the Friedman one-way repeated meas-ures analysis of variance by ranks was used for differences in enamel surface roughness between groups, with the Tukey post hoc test (a = 0.05). RESULTS: BRControl had the lowest SBS values (MPa), with a significant difference (P ≤ 0.001) from the other groups. Spot-etch+BR had the highest SBS values but with no significant differences from the other groups in which the spot-etch technique was also used. Adhesive failure mode was predominant for all groups. BRControl had the lowest surface roughness difference, significantly different (P = 0.001) from all the other groups. CONCLUSIONS: Spot-etch and other adhesive strategies could be applied to increase the SBS values of provisional restorations to enamel compared with no surface pretreatment. However, the adhesive strategy may change the enamel surface roughness, revealing the importance of cleaning the tooth surface.

Background: The crown is considered the most effective restoration for the management of dental caries. It reproduces the morphology and contour of the damaged coronal portion of the tooth while maintaining its function. The esthetic needs of children and the demands of parents bring advancement in dentistry toward a new era of esthetic crowns. In this era of esthetic crowns, the newly introduced preformed BioFlx crown seems to be an effective esthetic treatment option. Case description: In the present case series, full coverage restoration for the management of carious and pulp therapy-treated primary molars was done by esthetic and flexible BioFlx crown (Kids-e-Dental, LLP, Mumbai, India). Over a 6 months period, the crowns have demonstrated good retention and esthetic results. Conclusion: Dealing with the esthetic needs of children and managing primary molars using BioFlx crowns would be practical and successful. Clinical significance: The treatment described in the case series is a new advancement in pediatric dentistry with promising esthetic alternatives.

RESUMEN
Objective: Shared decision-making (SDM) is a collaborative process in which patients and healthcare providers jointly make a medical decision. This cross-sectional study aimed to identify the implementation status of shared decision-making among dermatologists engaging in medical esthetics in China and to identify factors associated with the good practice of SDM among them. Methods: From January to June 2023, a total of 1,287 dermatologists engaging in medical esthetics in China were recruited and completed the online interviews about their implementation of SDM based on the Shared Decision-Making Questionnaire for Doctors (SDM-Q-Doc). Logistic regression was used to calculate the odds ratio (OR) and 95% confidence interval (CI) to explore factors associated with the higher SDM score achievement among dermatologists with medical esthetic practice. Results: The median value of the total SDM score was 39, and 48% (621/1278) of dermatologists with medical esthetic practice achieved at least 40 out of 45 scores. Logistic regression indicated that dermatologists aged 40-49 or ≥ 50 years and those engaging in medical esthetic practice for ≥5 years were more likely to achieve at least 40 out of 45 scores compared to dermatologists aged <30 years with less than 5 years of medical esthetic practice. The ORs were 1.82 (95% CI: 1.13-3.12), 1.94 (95% CI: 1.13-3.61), and 1.76 (95% CI: 1.34-2.31), respectively. Conclusion: The SDM implementation level among Chinese dermatologists engaging in medical esthetics is high, especially for those who are older age and have more years of practice. Hence, it is highly recommended to promote and enhance SDM practice among younger dermatologists engaging in medical esthetics with less working experience.
RESUMEN
Enamel hypoplasia is an exclusive ectodermal disturbance, related to alterations in the organic enamel matrix which can cause white flecks, narrow horizontal bands, lines of pits, grooves, and discoloration of the teeth. It can result in compromised oral health that causes physiological and psychological disturbances. Management of enamel hypoplasia not only includes esthetic and functional rehabilitation of the patient but also requires a positive rapport building with the patient due to psychosocial issues. The present case reports elucidate step-by-step management of 16-year-old female patient who presented with localized enamel hypoplasia with severely decayed anterior teeth, poor dental esthetics, and oligodontia of the lower teeth.
RESUMEN
Unique anatomical deviations in canal structure are rare in anterior teeth, especially central incisors, and thus risk being overlooked. For successful intervention, a meticulous diagnostic procedure and treatment plan, significantly aided by cone-beam computed tomography (CBCT), are crucial. The case at hand explores the management of a maxillary left central incisor in a cleft palate patient, characterized by multiple developmental lobes, a bulbous crown, and an atypical root anatomy. The primary symptom was pain, accompanied by a history of trauma at age 8 years and ensuing tooth discoloration. Initial evaluations, augmented by CBCT, revealed pulpal necrosis in a single-rooted tooth with three distinct canals. Initial clinical examination was supplemented by electrical pulp testing, RadioVisioGraphy (RVG), and CBCT, after which the root canal therapy was initiated. Informed consent was obtained from the patient. The access cavity preparation resulted in a three-orifice cavity. Subsequently, the canals were enlarged and sufficiently debrided. Calcium-hydroxide was applied for 2 weeks before the commencement of apexification and obturation, followed by esthetic rehabilitation. This case highlights the importance of recognizing rare anatomical variations in anterior teeth and demonstrates the invaluable role of CBCT in both diagnosing and managing such complexities.
RESUMEN
Purpose: The aim of this study was to determine the relationship between the zygomaticomaxillary complex (ZMC) and infraorbital foramen region (IFR) with facial symmetry in patients with unilateral cleft lip and palate (UCLP) using cone beam computed tomography (CBCT). Materials and methods: In this retrospective study, CBCT images of 30 non-syndromic UCLP patients were included, along with 30 age- and sex-matched control individuals. ZMC symmetry was evaluated in the axial section by comparing the right and left sides. Similarly, symmetry in the IFR was assessed in the coronal section. The significance level was set at p<0.05 for statistical analysis. Results: The study group comprised 12 female and 18 male patients, with ages ranging from 10 to 18 years (mean age 14.1 years). Both ZMC and IFR measurements were significantly lower on the cleft sides of the study group compared to both the non-cleft sides of UCLP patients and the control group (p<0.001, p=0.022, and p=0.036, respectively). Furthermore, IFR measurements were significantly lower in the control group compared to the non-cleft sides of the study group (p=0.04). Conclusion: This study demonstrated that individuals with UCLP exhibit asymmetry in both the ZMC and the IFR. These findings suggest a negative impact on facial aesthetics.
RESUMEN
PURPOSE: In this study, we examined the facial, dental, periodontal, and tomographic features associated with excessive gingival display (EGD) when smiling in young adults self-reporting a "gummy smile," categorized by potential etiology. METHODS: The study included 25 healthy adults (18-42 years old; 23 women and 2 men) who self-reported EGD. Participants completed a health questionnaire and underwent a periodontal examination assessing probing depth, clinical attachment level, keratinized gingival width, and gingival thickness (GT). Extraoral and intraoral photographs were taken for smile analysis and to determine facial and dental characteristics. Cone-beam computed tomography (CBCT), performed with a lip retractor in place, was used to measure the distance from the gingival margin (GM) to the cementoenamel junction (CEJ), the distance from the CEJ to the alveolar crest, buccal bone thickness, and GT. The extent of EGD when smiling was quantified as the distance from the GM at the upper central incisor to the upper lip edge when smiling fully. The smile was categorized into 4 types based on gingival exposure characteristics observed during full smile. RESULTS: Most participants were female (92%), with a mean age of 28.77±6.56 years. The average EGD was 4.2±2.44 mm, extending bilaterally from the anterior to the posterior maxilla. Two primary etiological factors were identified, alone or in combination: vertical maxillary excess (VME), predominantly indicated by an anterior maxillary height greater than 29 mm and a large interlabial gap; and altered passive/active eruption (APE), primarily characterized by square teeth (64%), upper central incisor width-to-height ratio (CIW:CIH) exceeding 87.5%, and GM-CEJ distance on CBCT exceeding 2 mm. CONCLUSIONS: These findings suggest a multifactorial etiology of EGD, primarily associated with VME and APE. Clinical periodontal examination, CBCT conducted with a lip retractor, CIW:CIH, and soft tissue facial cephalometric analysis may aid in identifying the etiological factors of EGD.
RESUMEN
BACKGROUND AND PURPOSE: Gingival depigmentation impacts patient self-confidence and quality of life. This study compares the Er,Cr:YSGG laser to the traditional scalpel technique for reducing gingival hyperpigmentation, assessing their effectiveness and other relevant factors. PATIENTS AND METHODS: We conducted a double-blind, randomized trial with a split-mouth design. Forty participants were selected from the university's dental clinic and randomly assigned to receive either the Er,Cr:YSGG laser (2780 nm) or surgical scalpel. Pain intensity and smile satisfaction were assessed post-surgery, and treatment duration was evaluated. The Dummett Oral Pigmentation Index (DOPI) was used to determine the initial severity of pigmentation and to track both reduction and potential repigmentation over time. The Gingival Melanosis Record (GMR) was used to evaluate the presence and extent of pigmentation and to monitor recurrence after 1 and 12 months. RESULTS: Both the Er,Cr:YSGG laser and surgical scalpel similarly reduced GMR and DOPI scores over time, without significant differences at 12 months (p > 0.05). A significant examiner variability was noted in GMR scoring (ß = -1.2 for Examiner 2; p < 0.001). Power analysis indicated a higher confidence for detecting treatment effects in DOPI (75%) compared to GMR (55%). Patient satisfaction with smile significantly improved (p < 0.001). Treatment type did not influence postoperative pain levels. The Er,Cr:YSGG laser required longer surgery times (p < 0.001). CONCLUSION: Under the conditions of the present study, both Er,Cr:YSGG laser and surgical scalpel were equally effective in reducing gingival hyperpigmentation. Although lasers offer better bleeding control and require less anesthesia than the scalpel technique, clinicians should also consider surgery duration, cost, and expertise when selecting a treatment method. Future research should focus on long-term outcomes and economic evaluations, utilizing standardized clinical measures.
RESUMEN
This case report exhibits a heavy smoker female patient with a localized stage III periodontitis who has been under the smoking cessation program during the pre-surgical period, followed by a strict maintenance program for the past twelve years, after being treated with guided tissue regeneration techniques and restored with zirconia prosthetic crowns. A 50-year-old, heavy smoker (> 40 cigarettes per day), systemically healthy female patient presented complaining of mobility and pain in the upper right central incisor, which was temporarily splinted to the left central incisor using resin composite. After clinical and radiographic examination, significant damage of the attachment apparatus, deep periodontal lesions extending the middle portion of the root, and severe infrabony defect were noted. Following the initial hygienic phase, a guided tissue regeneration surgery using xenograft bone substitute covered by a resorbable collagen membrane was performed. After six months of healing, four zirconia crowns were cemented on the central and lateral incisors based on patient esthetic compliance. During the 12-year follow-up period, neither residual pockets nor gingival recession were observed, and perfect marginal bone stability, and esthetic and functional results were noted. This case shows the predictability of a conservative surgical technique, the guided tissue regeneration, based on appropriate treatment planning and a strict maintenance program. It also demonstrates the importance of at least a 6-month healing period after such surgeries, allowing complete tissue maturation and a re-establishment of the supra osseous gingival tissues in order to locate the prosthetic margins without interfering with the soft tissues integrity.
RESUMEN
Aesthetics are one of the primary goals of restorative care. Teeth that are traumatized in the anterior maxilla usually avulse or require extraction due to fractures. Rehabilitation is challenging in such a therapeutic state since it presents several anatomical and aesthetic issues. There are circumstances in which traditional implant placement is problematic. There must be enough bone for implant placement to be uneventful and successful. Other surgical therapies may be necessary in addition to implant placement for certain operations, such as extensive grafting, direct or indirect sinus lifts, and nerve lateralization. Certain procedures are required for these operations but are not always achievable. Because single-piece basal implants provide immediate temporization and loading while receiving adequate anchoring from the basal cortical bone, they have been extensively used to rehabilitate resorbed ridges. This case report demonstrates the placement of the basal implant in the anterior zone.
RESUMEN
OBJECTIVE: The aim of the present study was to provide recommendations in order to facilitate communication between dental professionals and surgeons who are collaborating in the field of dentofacial esthetics. CLINICAL CONSIDERATIONS: Smile esthetics are beyond the scope, both of the surgeons who are collaborating with facial esthetics and of the dentists, as a wide range of treatment options from both sides is available. It can be difficult for the surgeon or the dentist that first comes in contact with the patient to conduct an individualized global treatment plan, in order to find out how the various phases of the treatment can be sequenced, as a workflow for an efficient interaction between facial surgery and dentistry still does not exist in the scientific literature. CONCLUSIONS: Facial cosmetic procedures and dental treatment have to be planned as individual elements of the whole dentofacial esthetic rehabilitation. The treatment has to be initiated with the design of the smile and the intraoral mock-up, followed by the required surgical interventions, and to be finished with the delivery of the definitive dental restoration. CLINICAL SIGNIFICANCE: Dentofacial esthetics require comprehensive communication between surgeons and dentists. Following the proposed recommendations, an individualized interdisciplinary treatment plan can be conducted, defining the role of each specialty.
RESUMEN
Background/purpose: Many patients pursue attractive smiles, and surgical-orthodontic treatment is a common method. We aimed to analyze the changes in smile parameters after surgical-orthodontic treatment in patients with skeletal Class III pattern and identify factors influencing postoperative outcomes. Materials and methods: This retrospective study comprised 34 patients with skeletal Class III malocclusion and pure mandible prognathism who received surgical-orthodontic treatment. Hard and soft tissue parameters were assessed through lateral cephalometry, and smile esthetics were evaluated through extraoral photography. Postoperative changes in smile parameters and between-parameter correlations were analyzed. Random forest and decision tree deep learning models were used to identify factors influencing postoperative changes. Results: Substantial postoperative changes were observed in the buccal corridor, upper lip height, and smile index. Significant between-sex differences were noted in the upper midline and right chelion. Strong, positive correlations were found between upper lip height and upper lip ratio and between lower lip height and lower lip ratio. By contrast, strong negative correlations were observed between lower teeth exposure and smile index and between interlabial gap and smile index. The highest degrees of postoperative changes were noted in asymmetry-associated smile parameters: lower lip area, interlabial gap, smile index, buccal corridor, and arc ratio. Conclusion: Considerable changes were noted in skeletal, dental, and soft tissue parameters after surgical-orthodontic treatment. However, the changes in smile esthetics were less prominent from the frontal view. As for chin asymmetry, the most to least prominent changes were in the lower lip area, interlabial gap, smile index, buccal corridor, and arc ratio, respectively.
