The teeth position in anterior open bite malocclusion depends on a balance of pressure between the tongue and lips and the treatment planning should include such variables. The objective of this study was to report an orthodontic case of an adult with maxillary protrusion and anterior open bite treated with skeletal anchorage and intermaxillary elastics. The patient presented a Class II malocclusion with anterior open bite, without a history of non-nutritive habits, and mandibular missing teeth at 54 years old. Mini-implants were inserted in the maxillary molars region to produce distal movement of the maxillary dentition while controlling molar extrusion, and in the mandibular anterior region on the left side to produce mesial movement of posterior teeth. Up and down intermaxillary elastics were worn in the area of the incisors to treat the open bite together with Class II intermaxillary elastics. Cleats were bonded in the lingual surface of the anterior teeth as spurs to the tongue posture. However, the best result on the anterior open bite treatment was coincident with the speech therapy. Normal relationships between the maxillary and mandibular occlusal plane of cusps, correct anterior overbite, and adequate proximal relationships were obtained at the end of treatment. The retention modality to the maxillary arch was daily wear of a removable standard wraparound and a night-time wraparound with the palatal crib. The new technology allows for more effective treatment in adults and speech therapy was helpful to achieve balanced pressure between the tongue and lips.

Orthodontists generally recommend avoidance of certain foods during fixed appliance (FA) treatment, based on anecdotal information. This study aimed to identify the dietary preferences and experiences of patients undergoing FA treatment as a step toward the preparation of evidence-based dietary guidelines. Questionnaires regarding dietary preferences and experiences of patients undergoing FA treatment were applied to a convenience sample of 38 adolescents (12 M; 26 F). Open-ended responses were summarized and visualized in a world cloud generator. 5-point Likert and Visual Analog Scales (VAS) were used to record the closed-ended responses. Descriptive statistics and multivariate analysis of variance were used to analyze questionnaire findings. Lollies, apples, and nuts frequently caused problems with FA. The most frequent reason for avoiding certain types of food was worry about appliance breakage, followed by pain and sensitivity. VAS scores indicated that toffee and caramel scored highest (65.1% F and 54.1% M) for discomfort followed by corn on the cob (64.4% F and 48.7% M) and apples (56.6% F and 55.3% M). VAS scores did not differ significantly between the sexes (P > 0.05). Nearly, a quarter of the sample reported that FA negatively affected their eating behaviors, causing pain and discomfort during eating. No sex differences (P > 0.05) were found for negative experiences with food. Dietary preferences and experiences of patients undergoing FA treatment were identified concerning a New Zealand diet profile. A future study with a larger sample size will help formulate evidence-based dietary guidelines during FA treatment.

Smile is a universal phenomenon, the effect of which is not discovered on the lower anterior facial height (LAFH). The objective of this study was to determine the influence of smile on different LAFH in frontal view as assessed by different panels of raters using visual analog scale (VAS) in a female subject. The frontal photographs (at rest and on smile) were taken at natural head position of a female subject aged 28 years old after taking informed consent. LAFH of the photographs was modified using a Photoshop software (Adobe Systems, San Jose, Calif.). Sixty raters equally divided into orthodontic residents, general dentists, and laypersons were given a VAS to make subjective assessments of facial attractiveness of the modified photographs. Comparison of raters’ scores was done using Kruskal–Wallis and Mann–Whitney U-tests. Wilcoxon Signed-Rank test was used to compare the esthetic scores of the subject at rest and with smile. The mean age of the all raters was comparable (early adulthood). All raters preferred normal or slightly shorter LAFH in both postures, that is, at smile and rest. Similarly, all raters disliked long face modifications. On comparing smile and rest photographs at various LAFH, we found less VAS scores for smile. Gender of raters played no role in difference of VAS scores. All the panels of rater found normal LAFH to be the most attractive; however, the panels disliked long face modifications on both smile and at rest. Smile had no positive influence on the VAS scores as assumed so the effect of “Smiloflage” must be investigated further to understand it properly.

The intraoral use of commercial printable polymers in dental patients is still a challenge due to the unknown physical properties of the materials. The present study aimed to comparably evaluate the maximum load and deflection values of three-dimensional-printed resin blocks in different diameters that can be used intraorally in dental patients. Forty-five cylindrical resin blocks in diameters of 2 mm (Group 1, n = 15), 3 mm (Group 2, n = 15), and 4 mm (Group 3, n = 15) and lengths of 20 mm were designed and printed. The samples were placed in the universal testing device to conduct the 3-point bending test. According to the Shapiro–Wilk normality test results, Kruskal–Wallis and Mann–Whitney U tests were performed for the statistical analysis. The level of statistical significance was accepted as P < 0.05. The values for the maximum load (N) and deflection (mm) in the study groups were 218.4 ± 31.9, 2.96 ± 0.86 in Group 3; 77.05 ± 61.5, 3.91 ± 0.92 in Group 2; and 19.67 ± 2.63, 4.06 ± 1.02 in Group 1, respectively. The mean values of maximum load for Group 3 were superior to Group 2 (P = 0.020) and Group 1 (P = 0.00). Group 2 revealed higher maximum load results than Group 1 (P = 0.003). The mean values of maximum deflection in Group 3 were lower compared to Group 2 (P = 0.014) and Group 1 (P = 005). The results of this in vitro study encourage the use of resin-printed intraoral appliances in place of conventional treatment modalities.

The treatment plan for young patients with skeletal abnormalities is often selected by their parents. However, the treatment outcome should correspond with the patient’s preference to reduce the treatment need in the future. This study aimed to investigate the influence of post-treatment facial profiles in a skeletal Class II female subject on esthetic perceptions by laypeople of different age groups. Seven digitally adjusted profile images of predetermined nasolabial angle (NLA) and facial contour angle (FCA) were obtained from a female with skeletal Class II. These profile images were evaluated by 180 laypeople and were stratified according to three age groups (12–15, 22–32, and 44–54 years) using a visual analog scale and ranking order. The slightly convex profile with normal NLA (11° FCA and 91° NLA) was the most preferred by all age groups. The convex profile with the largest NLA (17° FCA and 115° NLA) was the least preferred by age group 12–15 and 44–54 years and the convex profile with normal NLA (17° FCA and 91° NLA) was the least preferred by age group 22–32 years. Sex was found to be significantly related to the rating score with females rated higher scores. The most attractive profile for all three age groups was a mandibular advancement-simulating profile. The least attractive profile for age groups 12–15 and 44–54 years was a most camouflage-simulating profile, while the least attractive profile for age group 22–32 years was an untreated most pronounced Class II profile.

Active vertical control is critical in the treatment of hyperdivergent skeletal Class II malocclusion. The mechanics have been well shown as successful in the fixed appliance system with temporary anchorage devices (TADs); however, there are few relevant case reports in clear aligner therapy (CAT). The present case report describes the treatment of a severe hyperdivergent skeletal Class II case using CAT with the extraction of four premolars. Active vertical control was performed with TADs, which was facilitated by intrusion bulbs (IBs), that is, digitally designed and preformed vacuum bulbs on clear aligners for wearing intrusive elastics. The challenging camouflage case was finished with an improved profile and occlusion; specifically, the upper central incisors were intruded for 3 mm and the first molars for 1.8 mm, with counter-clockwise rotation of the mandible for 2.2° and a decrease of the ∠ANB for 2.6°. After a 4-year follow-up (the latter 2 years without retainers), the treatment results remain stable on the whole. According to the case report, camouflage treatment of hyperdivergent skeletal Class II case can be successfully achieved with active vertical control using TADs, facilitated by preformed IBs on the clear aligners.

This study aimed to determine the efficacy of platelet-rich fibrin (PRF) injection on orthodontic pain perception during the 1st week of the alignment and leveling process. The study sample included 18 patients (11 females and 7 males). The patients were randomly divided into two groups, the PRF group (9 patients) and the control group (9 patients). The mean age of the sample members was 21.9 ± 2.5 and 20.8 ± 2.4 in the control and the PRF group, respectively. Conventional brackets were applied for both groups. PRF was injected into the six upper front teeth at a rate of 0.6 mm for each point before starting the primary wire insertion process. The pain parameters of each patient were evaluated for both groups during the 1st week of the alignment and leveling process by application of the Visual Analog Scale (VAS) at the durations of (2 h, 6 h, 1 day, 2 days, and 7 days) and all patients were followed up until the end of the alignment and leveling process. PRF injection can reduce pain perception in orthodontic patients, overall (P < 0.05), with an effect size of approx. 53 ± 0.13%. The biggest effect was observed 2 h after exposure (P < 0.1) which showed a 50% reduction in pain in the PRF group. No significant effects were observed at later times (P > 0.1). The present study concludes that PRF injection can be an effective alternative for decreasing pain perception levels; however, its efficacy needs to be leveraged immediately after the injection of PRF.

Patients frequently use social media platforms to obtain information on dental treatment. This study aimed to evaluate the quality of the content prepared for patients seeking information on laser-assisted surgical treatment of the gummy smile on the YouTube platform. Videos were searched on YouTube using the keyword “fix gummy smile” in Google Trends. Considering the exclusion criteria, 30 out of 119 videos were selected for the study. Videos were analyzed in terms of general characteristics, video uploader, video content quality (VCQ), video information and quality index (VIQI), and Global Quality Scale (GQS). Statistical significance was established at P < 0.05. The average VCQ of the videos was 3.07 ± 1.39 out of a maximum of 30. Most videos (46.7%) were uploaded by dentists and 23.3% by healthcare institutions. Considering the video uploader, no significant difference was found in VCQ, VIQI, and GQS (P > 0.05). There was a positive correlation among the interaction index, the number of likes, and the reliability score (P < 0.05). Moreover, reliability score showed a positively directed association with GQS, total VIQI score, and total VCQ score (P < 0.01). Clinicians who upload content to YouTube should consider the importance and potential of YouTube to provide information to communities and create videos with more intellectual content to facilitate access to accurate information, especially related to health.

The eruption of the second molars may delay the therapy and lengthen the treatment time. To minimize excessive treatment prolongation, the principle of resistance factor elimination was applied to the unerupted second lower molar through a surgical incision on the occlusal gingival tissue. The 3.7 was successfully erupted and easily bonded the following month, to allow the archwires sequence.

The purpose of this study was to evaluate the relationship between psychosociocultural factors and dental malocclusion, facial appearance, and body perception. The study was carried out with the participation of 112 female and 113 male individuals between the ages of 18 and 25. Individuals were asked to answer the Rosenberg Self-Esteem Scale, Physical Appearance Comparison Scale Revised, and Sociocultural Attitudes Towards Appearance Questionnaire 4-Revised questionnaires. Individuals were divided into three groups Class I, Class II, and Class III according to dental molar relationships. Standard facial and profile photographs of individuals in all groups were taken and soft-tissue measurements were performed. There was no significant psychosociocultural difference between male and female individuals. However, individuals with Class III dental malocclusion compare their physical appearance more than other malocclusion groups and more experience body dissatisfaction (P > 0.05). Individuals with Class III dental malocclusion have higher lower face height, lower lip height, mentolabial angle, facial convexity angle, total facial convexity angle values, and lower forehead height/lower face height, nose height/lower face height ratio, and projection of the upper lip relative to the chin. Individuals with Class II dental malocclusion have lower chin height and anterior mandibular height/lower face height ratio, higher upper lip height/lower face height ratio, and upper lip height/anterior mandibular height ratio. Individuals with Class I dental malocclusion have a lower upper face height/lower face height ratio. Dental malocclusion groups have different facial soft tissue properties. Dental malocclusion and the facial appearance of individuals affect their lives in terms of psychosociocultural aspects.
