Objectives: This study aimed to assess the skeletal maturation by using salivary DHEAS levels and its correlation with existing skeletal maturity parameters represented by cervical vertebrae and MP3 region radiographs in adolescents in pre-pubertal and pubertal age groups.Methods: In this study, 80 children in the age range of 8 - 14 years were divided into two equal groups based on their chronological age as group I (pre-pubertal group) and group II (pubertal group). Pre-existing lateral cephalograms and medial phalanx of third finger (MP3) radiographs of their left hands were assessed. The levels of the DHEAS of each individual were analysed by ELISA kit. ANOVA with post-hoc Tukey’s test and student t-test were used for statistical analysis. P-value < 0.05 was considered significant. Results: The mean level of DHEAS values shown in the present study was 4.36 +/- 0.32 ng/mL in group I and 5.73+/-0.39 ng/mL in group II. This study showed that in group I, more subjects were in stage 1 of cervical vertebral maturation than stage 2 and there were significant differences between the two stages (P-value = 0.011); also, in group II, more subjects were in stage 3 than 4 and there were significant differences between the two stages (P-value = 0.017). This study revealed the highest salivary DHEAS levels to be in the F stage of pre-pubertal MP3 development in addition to the H stage of MP3 development in pubertal children. This study noted that there were significant differences for salivary DHEAS levels between males and females not only in pre-pubertal (P-value = 0.031), but also in pubertal stages (P-value < 0.001).Conclusions: Salivary DHEAS, like cervical vertebra and MP3 radiographs, can be used for growth assessment in young adolescents.

Introduction: Macrodontia or Megadontia or Megalodontia is simple enlargement of all tooth structures. Most of the literature regarding this condition belongs to 1970’s and 80’s and very recent clinical case reports in different ethinic groups are lacking. The etiology of unilateral versus bilateral macrodontia of premolars is unexplained till date. The prevalence of macrodontia of premolars in mandible is higher than in the maxilla. Isolated macrodontia of second premolars has been known by many synonyms like “Macrodont molariform premolars” and “Megadonts”.
Case Presentation: A 16 year old male adolescence patient had reported with a complain of forwardly placed upper front teeth. Routine clinical examination revealed a uniquely-appearing second premolar on the right side of the mandibular arch. The surface area of the crown was two to three times greater than that of normal premolars. There was crowding of the lower anterior teeth with labial placement of lower canines. The intraoral periapical radiograph showed a huge premolar tooth with a single, short, stunted and tapering root. The Model analysis favours expansion of the mandibular arch and extraction of the premolar teeth in maxillary arch for contraction of the arch.
Conclusions: For proper space management, any developmental anamoly involving the shape of the tooth such as a macro premolar or an erupted odontome has to be extracted as early as possible, as part of the orthodontic treatment plan and fixed appliance therapy initiated. Treatment of macropremolars is a challenging task for the orthodontist, as it requires accurate space analysis and space management.
