Spectrophotometric Evaluation of Color Change in Tooth Enamel Defects Using Resin Infiltrate: An In Vivo Study.

AIM: To analyze the comparative change in pretreatment and posttreatment La*b* values of color in initial nonpitted white spot lesions of fluorosed teeth after resin infiltration with DMG-Icon spectrophotometrically with VITA easy shade. MATERIALS AND METHODS: A total of 30 maxillary and mandibular permanent anterior teeth with mild, nonpitted white spot lesions (atleast one) of fluorosis [till grade IV of Thylstrup and Fejerskov (TF) index] in patients between 6 years and 14 years of age were included in the present study. Shade of selected tooth and its white spot lesion area was recorded using VITA 3D shade guide, both pre and postoperatively, i.e., after application of DMG Icon. This was followed by recording the change in corresponding La*b* values of tooth shade and white spot lesion spectrophotometrically using VITA Easy Shade. Results obtained were analyzed statistically. RESULTS: ΔE value of color change was found to be less than 3.7 in most of samples after resin infiltration and esthetically color change to naked eye was statistically significant (p value < 0.00001) postoperatively. CONCLUSION: Resin infiltration with DMG Icon can improve the color of non-cavitated white spot lesions. The esthetic effect of this treatment was evident immediately after treatment. Moreover, no cavitation occurred after etching, even when the surface layer had been eroded completely. CLINICAL SIGNIFICANCE: Achievement of esthetic results without loss of tooth structure and postoperative sensitivity. HOW TO CITE THIS ARTICLE: Dogra S, Goyal V, Gupta A, et al.

Hemifacial microsomia managed by distraction osteogenesis: A clinicoradiological report.

Hemifacial microsomia (HFM) is a congenital malformation in which there is hypoplasia of hard and soft tissues on one side of the face. It is considered the second most common congenital syndrome of the head-and-neck region. The hypoplasia manifests in all the structures derived from the first and second branchial arches and therefore, growth and development of these structures is affected in this condition. The present case is a variant of HFM in a 5-year-old Indian male child, which has been diagnosed based on clinical and radiological findings and managed successfully by surgical technique known as distraction osteogenesis.

Experience with Anterior Maxillary Osteotomy Techniques: A Prospective Study of 20 Cases.

AIM: This prospective study aimed at studying the complications associated with different techniques of anterior segmental maxillary osteotomy. MATERIAL AND METHOD: The study was conducted on 20 cases diagnosed with anteriorly prognathic maxilla with class 1 molar relation. The patients were followed up for a period of at least 1 year. The clinical and demographic data along with the intraoperative and postoperative complications associated with different treatment techniques were recorded. RESULTS: In five cases, Wassmund technique was followed with average time span of 32 min. Wunderer and Cupar technique took average time span of 23 min. Two patients presented with four non-vital teeth in a follow-up period of 1 year and one patient treated with Cupar's technique had complication of palatal tear. Only one patient reported with relapse in a follow-up period and none of the patients had any complication associated with hemorrhage, neurosensory alteration or requiring plate removal. The findings of our study recommend ASMO as treatment modality of choice in patients with bimaxillary and/or dentoalveolar protrusion with Cupar's technique providing more ease of operation.
