“…Based on the acceptable difference (about 2-3 mm) between the dental median line and the facial median line, the largest correlation between incisive papilla and facial midline was observed without a clear reference point in the maxillary median line [9] . The maxillary labial frenum, being a bridge between the facial median line and the dentition, plays a very important role in determining more accurately the relationship between the two [10] . Farahani et al [10] con rm that the labial frenum deviates less from the median line than the incisive papilla does.…”

Background: Infant labial frenum morphology will directly lead to the midline diastema between maxillary deciduous tooth，which locates in the facial aesthetic area。 facial aesthetic area causes family members' medical demands. Objective: To explore the correlation of infant labial frenum morphology and maxillary deciduous tooth eruption with the age of infants and provide theoretical support for clinical practice. Methods: 1,268 infants (730 males and 538 females) of 5-36 months old who had routine physical examinations in the Children’s Health Center of Maternal and Child Health Hospital of Ningxia Hui Autonomous Region in 2022 were selected. Multiple linear regression was used to assess the correlation of labial frenum morphology with age and the correlation of maxillary deciduous tooth eruption with age. The age discrimination equation between different genders was also established. Results: There was a negative correlation between labial frenum morphology and age (male: r=-0.567, female: r=-0.571, P<0.001) and a close relation between maxillary deciduous tooth eruption and age (male: r=0.769, female: r=0.803, P<0.00). Conclusion: The correlation of labial frenum morphology and maxillary deciduous tooth eruption with age can provide guidance to the aesthetic anxiety of infants’ family members.

Introduction: One of the main elements of facial esthetics is represented by the smile. A harmonious proportion between the elements of facial esthetics is an important subject of interest in dentistry. Aim of the study: This research aims to evaluate the impact of the gummy smile on future dental practitioners. Materials and Methods: A survey containing 16 questions was designed to find out the students’ perceptions about the ideal smile and if the gingival smile is considered youthful or unpleasing. The impact on their self-esteem, their willingness to change the gummy smile or not, the nonsurgical and surgical methods of treatment were also evaluated. Results: 212 answers were recorded and analyzed. Nearly three quarters (70.3%) of the respondents believe that having a gummy smile is unesthetic, while only 29.3% considered it to be a sign of youth. Self-esteem can be affected by having a gingival smile, but, according to the results, most of the students (45.8%) said that their daily lives have not been affected by it, 40.6% said that in a small amount, 10.4% said that their self-assurance has been very affected and only 3.3% admitted that the gummy smile distressed their confidence. When asked if they were willing to correct their gingival smile, 51.4% were open to improving it while 48.6% would not change it. Conclusions: Among dentistry students, excessive showing of the gums is believed to be unesthetic rather than a sign of youthfulness. The respondents are generally not affected in their daily life by having a gummy smile. Education regarding the methods of correcting it still needs to be addressed amongst future dental practitioners.

“…On the back of the casts, the last molars were marked by vertical lines through their buccal and palatal cusps to identify the arch form. [ 5 6 ] Later, teeth were cut with precision using a fine saw from the gingival side until just before the contact points. A clean line fracture was then produced by using small manual forces to propagate the cut through the contacts.…”

OBJECTIVE: A novel technique, named the MH setup (MH is an abbreviation for the author's name), was developed to provide an accurate yet simplified method to produce custom-made brackets without bonding errors. This setup aimed to simplify the treatment and eliminate the finishing phase, so that the orthodontist was able to provide better care with less time and lower costs. MATERIALS AND METHODS: The setup was performed in two major steps: direct bonding on the cast followed by cutting and setting the teeth into precise positions using brackets. The first set of brackets, bonded directly onto casts, oriented the teeth by setting them ideally into wax rims with full control over first-, second-, and third-order bends. The fully engaged archwire used allowed for precise control over the arch symmetry and form. Setting teeth in wax allowed the clinician to refine the occlusion and correct any minor errors that arose during the initial bonding. The second set of brackets, mounted on the fully engaged archwire, featured custom-made composite bases. The transfer tray combined the benefits of its soft inner and hard outer layers, providing control over bonding and later ease of peeling from the brackets. RESULTS: The patient was satisfied with a full bonding procedure lasting 15 min that remained simple without unnecessary stress. The clinician was confident that the procedure allowed the precise positioning of brackets and simple bonding for all teeth in the arch, combined with the elimination of the finishing phase. CONCLUSION: The MH technique offered a simple, precise, and inexpensive improvement to the Kesling wax setup. The process allowed for precise bonding without errors or expensive armamentarium. The brackets were transformed into custom-made prescriptions and could be used with labial or lingual techniques. The method allowed for teeth addition, trimming, or overcorrection according to the clinician's preferences. The MH setup facilitated visualization of the treatment objectives with precise locations and the opportunity to revise the treatment plan or to discuss further options with the patient.
