However, if demanded, composite facings or composite strip crowns can be added for aesthetic reasons. Endodontics Treatment
Endodontic intervention can help conserve the existing health of affected permanent teeth. It is difficult to perform an endodontic therapy on teeth that develop abscesses as a resultant of obliteration of the pulp chambers and root canals. An alternative to conventional therapy would be retrograde filling and periapical curettage. However, these therapies are not recommended for teeth with roots that are too short. Removable dentures
Teeth with short thin roots and marked cervical constrictions are less favourable for indirect restorations such as crown placements. If endodontics treatment fails, and abscess develops around the root apex, extraction of the affected teeth would be the best treatment option. Dentures or over dentures can be considered, as rehabilitation until growth is completed. Cast partial dentures could also be an alternative treatment option and it only works if there are a few teeth that has enough root length to serve as retentive purpose. Dental implants
Dental implant is one of the treatment options that can be considered when growth is fully attained. For patients who experience maxillo-mandibular alveolar atrophy due to early loss of teeth, alveolar ridge augmentation procedure is recommended prior to the implant placement. Both onlay bone grafting and sinus lift techniques can be carried out together to accomplish implant placement. References

The former type is, for example, shift work sleep disorder, which affects people who work nights or rotating shifts. The intrinsic types include:
Advanced sleep phase disorder (ASPD) – A condition in which patients feel very sleepy and go to bed early in the evening and wake up very early in the morning
Delayed sleep phase disorder (DSPD) – Faulty timing of sleep, peak period of alertness, the core body temperature rhythm, hormonal and other daily cycles such that they occur a number of hours late compared to the norm, often misdiagnosed as insomnia
Non-24-hour sleep–wake disorder – A faulty body clock and sleep-wake cycle that usually is longer than (rarely shorter than) the normal 24-hour period causing complaints of insomnia and excessive sleepiness
Irregular sleep–wake rhythm – Numerous naps throughout the 24-hour period, no main nighttime sleep episode and irregularity from day to day

Physical illness
Sleepiness can also be a response to infection. Such somnolence is one of several sickness behaviors or reactions to infection that some theorize evolved to promote recovery by conserving energy while the body fights the infection using fever and other means.
