Tooth loss in the very old: 13-15-year incidence among elderly Iowans.

OBJECTIVES: Very few studies have reported tooth loss incidence over a period of 10 years or more, and fewer have reported tooth loss occurrence in subjects aged 80 and older, so that the long-term pattern of tooth loss in the very old is largely unknown. This study assessed 13-15-year tooth loss incidence among a cohort of Iowans, aged 65 and older at baseline. METHODS: Oral examinations were conducted on 520 subjects beginning in 1983, and periodically until 1988, with another round of examinations conducted on surviving members of the initial cohort during 1996-98. RESULTS: Of the 73 remaining subjects, 45 subjects lost a total of 153 teeth during the period (mean=2.1 teeth lost), with a maximum of 17 teeth lost. Molars were the most commonly lost teeth, while canines and maxillary incisors were the least commonly lost. Bivariate analyses found that tooth loss was associated with untreated decay at baseline and level of periodontal attachment loss at earlier examinations. Logistic regression identified only greater severity of attachment loss as a significant risk factor for tooth loss (Adjusted odds ratio=2.4, P=0.006). The impact of tooth loss on subjects' lives was assessed using OHIP and other questions. The occurrence of tooth loss over the study period had little impact, but the number of remaining teeth significantly impacted subjects' ability to eat or chew food, swallow, or their willingness to smile. CONCLUSIONS: These results suggest that tooth loss continues in the very old, that periodontal attachment loss is associated with tooth loss in this age group, and that loss of teeth over one's lifetime does affect certain quality-of-life measures.

Endodontic management of an impacted premolar.

This report demonstrates a simple endodontic solution to an interdisciplinary case of a patient with multiple gene deficiencies. An adolescent patient presented with an impacted premolar that could not be extracted due to high-risk conditions. A suspicious degree of radiolucency around the crown was clinically diagnosed as dentigerous cyst. The treatment dilemma and implementation are discussed. This case report offers a different treatment option for impacted teeth when significant differential diagnosis of a pericoronal lesion dictates treatment.

Treatment of ectopic mandibular second molar with titanium miniscrews.

The use of a Cizeta titanium miniscrew (Cizeta Surgical, Bologna, Italy) for treating an impacted mandibular second molar is presented in this report. The surgical procedure for placing the miniscrew and the subsequent orthodontic management are described, including orthodontic traction with a nickel-titanium closed-coil spring exerting 50 g of force. We concluded that the titanium miniscrew for skeletal anchorage is effective in treating deeply impacted mandibular second molars.

Keeping your eye on the ball.

Dentigerous cysts develop from unerupted and impacted permanent teeth. Very rarely, supernumerary teeth are associated with dentigerous cysts and constitute about 5-6% of all dentigerous cysts. Although these cysts are not common in the first decade of life, regular thorough inspection of radiographs is of importance, as indicated by this case report. This case shows how an impacted supernumerary canine developed a dentigerous cyst, engulfing the whole of the maxillary antrum.

Diagnosis and prevention of maxillary cuspid impaction.

Early diagnoses and prevention of maxillary cuspid impactions can save much time when treating patients orthodontically. Effective recognition and interception requires initial diagnosis at the dental age of about eight years. When a cuspid bulge is absent, diagnosis with oriented lateral and frontal radiographs is advocated and has been shown to aid in the positive recognition of lingually positioned unerupted maxillary cuspids at risk for impaction. Recommended treatment is early removal of maxillary deciduous cuspids and perhaps deciduous first premolars. Lateral and frontal radiographs should be taken at six-month intervals to follow the intra-bony eruptive movement of the permanent cuspids until they have entered the oral cavity. Failure to diagnose and intercept the potentially impacted cuspid often leads to serious malpositions that require extensive mechanical therapy for proper alignment and good function.

Inverted impaction of a mesiodens: a case report.

Dental, radiological, dermatoglyphic and genetic findings of a patient showing inverted impaction of a mesiodens are presented. It is probable that the inversion of the mesiodens was caused by contact of the incisal edge of the crown of the mesiodens by the apex of the root of the erupting right maxillary central incisor tooth.

[Eruption of canines through alveolar bone grafts in cleft lip and palate].

62 patients with clefts of the alveolus who had received alveolar bone grafts (iliac crest) at ages 8.6 to 12.8 years (mean 10.1 years) were studied. The eruption of 73 canines from 11 bilateral and 51 unilateral cleft patients could be evaluated. The postoperative observation period ranged from 2 to 16 years (mean 9 years). Spontaneous eruption occurred for 77% of the canines, 20% required surgical uncovering either bony or/and soft tissue. One canine had to be removed and one canine is still impacted.
