“…Some studies suggested sex-related differences (17,20). However, our current study supported that the prevalence of the distolingual root according to sex showed no statistical significance, which was similar to the Taiwanese population (9,18).…”

“…This percentage was higher than the results of some studies on Asians (5,18,19) but lower than the studies on Korean children (33.1%) and Eskimo adults (32.0%) that used a two-dimensional radiograph (17,20). This variation could be attributed to the use of 3D image analysis, which provides more accurate determinations, leading to clearer conclusions about less common anatomic variations like the distolingual root in first molars.…”

“…The prevalence of a supernumerary root in mandibular primary first molars is estimated at 5% in Taiwanese [2] and 9% in Chinese [3] populations, whereas the occurrence of bilateral mandibular three-rooted primary teeth is only 1% [2]. According to Song et al [4], the probability of the tooth posterior to a mandibular primary first molar with three roots is greater than 94.3%, but in our cases the primary mandibular second molars had two roots.…”

Variations in dental development are not uncommon, however diagnosing such anomaly remains a challenge for the clinician. Tratman [1] stated that dental anomalies are rarer in primary dentition than in permanent dentition. Primary mandibular first molars usually have two roots -mesial and distal.The following are two case reports where the first molars had three roots and a broader occlusal table resembling a primary maxillary molar, which posed a challenge during the dental treatment and required certain modifications of the routine procedures. Case Report 1A 4-year-old male patient reported to the dental clinic with a complaint of multiple decayed teeth. The patient's medical and family histories were noncontributory. On clinical examination, the patient had deep dentinal caries in the lower molars. The first primary molars were broader in dimension than normally seen. Routine diagnostic radiographs were made which revealed deep dentinal caries approximating the pulp in 74 and 84. Both the first primary molars had three roots -mesial, distal and lingual ( Fig. 1, 2). AbstractThough variations in dental development are not uncommon, dental anomalies are rarer in primary dentition than in permanent dentition. Diagnosing such anomaly remains a challenge for the clinician. Primary mandibular first molars usually have two roots -mesial and distal. This article is a report of two cases with atypical crown and root morphology of the primary mandibular first molars. Both cases discussed had a bilateral crown and root variations where 3 roots were found in the primary mandibular first molars. All the teeth reported in this case report had a broader occlusal table resembling a primary maxillary molar, which posed a challenge during the dental treatment and required certain modifications from the routine procedures. The article focuses on diagnosis and modifications in the routine clinical procedures to be followed for such cases. The article also emphasizes the importance of preoperative radiographs in alerting the clinician to the presenting clinical challenge (Dent. Med. Probl. 2016, 53, 4, 566-569).
