SummaryDeinococcus radiodurans R1 recovering from acute dose of γ γ γ γ radiation shows a biphasic mechanism of DNA double-strand break repair. The possible involvement of microsequence homology-dependent, or nonhomologous end joining type mechanisms during initial period followed by RecA-dependent homologous recombination pathways has been suggested for the reconstruction of complete genomes in this microbe. We have exploited the known roles of exo-

Odontogenic anomalies of teeth can be encountered frequently in dental practice. Fusion and gemination are developmental anomalies leading to eruption of joined elements as double teeth. These anomalies pose a challenge even to the most experienced clinician in treating these teeth. This article highlights the importance of clinical and radiographic correlation in arriving a definitive diagnosis.
