The prevalence of gingival physiologic pigmentation in three ethnic groups of a total of 2,465 Israeli Jews were determined. The distribution of this gingival pigmentation, according to anatomic parts and divisions, was examined. Results showed the presence of gingival pigmentation in 57.9% of the Eastern group, 49.3% of the Sephardic group, and 21.1% of the Ashkenazi group. No indication of sex predilection was found. The most common site of pigmentation was the labial part of the gingiva, and the attached gingiva was the most common pigmented anatomic division. The group of Eastern Jews showed the highest prevalence of physiologic pigmentation in each of the anatomic parts and divisions of the gingiva.

Physiologic pigmentation of the oral mucosa in Israeli Jews of different ethnic origin.

The prevalence of oral physiologic pigmentation in three ethnic groups of a total of 2465 Israeli Jews was determined, and the relationship of oral pigmentation to age and sex within the groups was noted. Results showed the presence of oral pigmentation in 63.6% of the Eastern group, 54.8% of the Sephardic group, and 24.9% of the Ashkenazi group. No indication was found of sex predilection, and no significant trend was evident in the prevalence of pigmentation with relation to age. The leading site of pigmentation among the entire sample was the gingiva, and this finding did not vary with ethnicity.

Severe infraclusion ankylosis: report of three cases.

Tooth ankylosis may occur at any time during eruption and may show varying degrees of infraclusion. Cases of fully erupted teeth subsequently becoming totally embedded in bone are rare. The three reports described here show cases of severe infraclusion ankylosis; the etiology and related problems are discussed. Associated periodontal, prosthetic and orthodontic problems can be avoided with early diagnosis and treatment.
