BackgroundIn contemporary dental care, an increasing number of adult patients are now seeking orthodontic treatment with the primary motive of improvement in appearance and achievement of esthetic smile. Proper recognition of the dental and facial defects at the outset of treatment is the most important key to esthetic success and is essential in satisfying the patient’s needs. By following the rules of Golden proportion smiles can be made attractive, harmonious, symmetrical, and proportionate.MethodologyConsisted of 22-year-old girl who came for treatment of crowding in maxillary and mandibular arches, abnormal overjet and overbite and had unesthetic peg lateral.ResultsNon-extraction therapy was carried out since the patient had good soft tissue drape, alignment was achieved by expanding the arches and moving teeth in ideal axial inclination. Esthetic smile was attained using composite buildup of upper right peg lateral and minor adjunctive surgery (full thickness periodontal graft) on lower right central incisor.ConclusionThe present case report orchestrates interrelationship between various branches of dentistry and orthodontics. It exhibits how multidisciplinary approach can be used to achieve ideal dental esthetics in a 22-year-old girl who was successfully treated for peg shaped lateral incisor, gingival recession, and unesthetic smile.

Aim: To determine the co-relationships of the root crown length and occlusal contacts in patients with Class-III skeletal relationship, anterior open-bite, and high mandibular plane angle. Materials and Methods: Study group consisted of 10 untreated Class-III patients with reverse over jet of minimum-2 or more and an anterior open-bite. Control group consisted of untreated patients with average 0-4 mm of over jet and overbite. Dental casts, orthopantomograms, and lateral cephalograms were recorded for measuring the root and crown lengths, occlusal contacts, and mandibular plane angle readings and were analyzed. Results: The root length and the root-crown ratios were reduced from incisors toward the pre-molars in the study group. Occlusal hypofunction was seen associated with the study group. Short dental roots were observed specifi cally with the anteriors. Conclusion: Patients with Class-III skeletal relationship, high mandibular plane angle, and an anterior open-bite have a tendency toward developing short dental roots that can be associated with occlusal hypofunction that is associated with the condition.

Objectives: This in vitro study aimed to compare the resistance to enamel demineralization after banding with three orthodontic cements, namely Zinc Phosphate, Zinc Polycarboxylate and Resin Modified Glass Ionomer Cement [RMGI] (Fuji Ortho Band Pak, GC). Materials and Methods: 80 premolars were selected, cleaned, dried and divided into four groups. Group A was a Control group. Group B, C and D were banded with the stainless steel bands using the respective cements. The teeth were then placed in deionized water for one month. They were debanded, cleaned and placed in artificial demineralizing solution for four weeks. Afterwards, they were cleaned and placed in methylene blue for 24 hours to check the amount of demineralization. The teeth were cut buccolingually and observed under the Motic Image Digital microscope. For analysis, the depth of dye penetration was measured in µm, which was considered as the depth of sub superficial demineralization. Results: RMGI cement showed significantly lower amount of demineralization (6.68 ±3.02µm) compared to the Zinc Polycarboxylate cement group (18.08± 5.83µm). The Zinc Phosphate cement group(55.36±8.67µm) and the Control group(76.72±18.83µm) demonstrated the greatest depth of enamel demineralization. Overall comparison showed a statistically significant difference (F=187.97, p<0.001). Conclusions: RMGI used for banding achieves the greatest resistance against enamel demineralization in comparison with zinc phosphate and zinc polycarboxylate cements.
