ABSTRACT Objective: The aim of this study was to evaluate the skeletal and dental effects of rapid maxillary expansion (RME) in cleft patients using two types of expanders. Methods: Twenty unilateral cleft lip and palate patients were randomly divided into two groups, according to the type of expander used: (I) modified Hyrax and (II) inverted Mini-Hyrax. A pretreatment cone-beam computed tomographic image (T0) was taken as part of the initial orthodontic records and three months after RME, for bone graft planning (T1). Results: In general, there was no significant difference among groups (p > 0.05). Both showed a significant transverse maxillary expansion (p < 0.05) and no significant forward and/or downward movement of the maxilla (p > 0.05). There was greater dental crown than apical expansion. Maxillary posterior expansion tended to be larger than anterior opening (p < 0.05). Cleft and non-cleft sides were symmetrically expanded and there was no difference in dental tipping between both sides (p > 0.05). Conclusions: The appliances tested are effective in the transverse expansion of the maxilla. However, these appliances should be better indicated to cleft cases also presenting posterior transverse discrepancy, since there was greater expansion in the posterior maxillary region than in the anterior one.

Research objective. The study aimed to evaluate cone-beam computed tomography (CBCT) capabilities in diagnostics of cystic masses of the jaw.Methods. Over a period of 2015–2016 32 patients age 6 to 67 underwent both panoramic tomography and CBCT (using panoramic tomographic scanner STRATO 2000 and cone-beam computed tomographic scanner i-Cat respectively). 47% (n = 15) of the participants were women, 53% (n = 17) – men. Radiation exposure for a single procedure amounts to 0,05 mSv for panoramic tomography, 0,07 mSv for CBCT (FOV =13 cm), 0,06 mSv for CBCT (FOV =8 cm).Results. Comparative analysis of obtained results demonstrates that CBCT showed 54% (n = 27) more cystic masses of the jaws than panoramic radiography could. CBCT additionally showed the following pathologies: granulomas smaller than4 mm diameter – 85% (n = 23), 83% (n = 23) of said granulomas were found on maxilla, radicular cysts of maxilla – 11% (n = 3), incisive canal cyst – 4% (n = 1). Additionally panoramic tomography analysis misdiagnosed 5 granulomas (80% (n = 4) on mandibular premolar and molar areas) that were not found during CBCT analysis.Conclusion. The low effective dose and high informativity of CBCT enables the method to be used instead of intraoral radiography, panoramic tomography and MSCT as a screening procedure in diagnostics of dento-facial system pathologies, including cystic masses of the jaw.

Objective: The complex root canal anatomy is inherently colonised by microbial flora. Endodontic treatment success is always related to adequate disinfection of the root canal space, which ultimately affects the treatment outcome. A thorough understanding of the external and internal root canal anatomy by using adequately imaging modalities is essential before planning any treatment. The aim of this study was to investigate the number and morphology of the root canals of maxillary and mandibular premolars in Chennai population. Material and Methods: Full-size cone-beam computed tomographic images were randomly collected from 100 patients, resulting in a total of 200 first and 200 second maxillary premolars as well as 200 first and 200 second mandibular premolars. All the eight premolars were analysed in single patients, who underwent cone-beam computed tomography scanning during pre-operative assessment (before implant surgery, orthodontic treatment, diagnosis of dental-alveolar trauma or difficult root canal treatment). Total number of roots and root canals, frequency and correlations between men and women were recorded and statistically analysed by using chi-square tests. The root canal configurations were rated according to the Vertucci’s classification. Results: In the maxillary first premolar group (n = 200), 36.3% had 1 root, 56.7% had 2 roots and 7.0% had 3 roots, with most exhibiting a type IV canal configuration. In the maxillary second premolar group (n = 200), 60% had 1 root, 29.8% had 2 roots and 10.2% had 3 roots, with the majority of single-rooted second premolars exhibiting a type I canal configuration. In the mandibular first premolar group (n = 200), 80.5% had 1 root, 9.8% had 2 roots and 5% had 3 roots. In the mandibular second premolar group (n=200), 90.1% had 1 root, 6.4% had 2 roots and 3.5 % had 3 roots, with most exhibiting a type I canal configuration. No statistical correlation was found between number of roots, gender and tooth position. Conclusion: This cone-beam computed tomographic study confirmed previous anatomical and morphological investigations. Therefore, the possibility of additional root canals should be considered when treating premolars. Keywords: Cone-beam computed tomography; Mandibular; Maxillary; Premolar; Root canal; Morphology.
