“…The formation of the accessory mental foramen was attributed by some authors to the occurrence of earlier separation of the mental nerve (Naitoh et al, 2009). Additionally, variations in the incidence of accessory mental foramen between ethnic groups are present (Toh et al, 1992;Sawyer et al). In the present study, we observed accessory mental foramina in 7.3 % of the cases.…”

SUMMARY:Accurate information regarding the vertical location and appearance of the mental foramen, and the presence of accessory foramina, can have clinical significance, such as reducing complications that may occur during many oral surgical procedures involving the mental area. Geographic variations were reported in these variables. The aim was to evaluate the above-mentioned variables in an Iraqi sample. Five hundred eighteen panoramic radiographs of a random Iraqi sample (257 males, 261 females, average age= 46.5 years) were evaluated with regard to the above-mentioned variables, as well as the symmetry of the foramen regarding these variables. The area below the apices of mandibular premolars, and the continuous type were the most frequent vertical location and appearance of the mental foramen, respectively. Age advancement was found to be associated with an increase in the frequency of more inferior positioning and continuous appearance. The vertical position and appearance were asymmetrical in 16.2 % and 20.1 % of cases, respectively. Symmetry in the vertical location was statistically significant between sexes (P= 0.035), and young and old ages (P= 0.000). Symmetry in the appearance was found statistically significant (P= 0.025) only between the two age groups. Accessory foramina were recorded in 7.3 % of cases. The most common vertical location and appearance of the mental foramen on panoramic radiographs in this group are below the apices of mandibular premolars, and continuous type, respectively. This is in consistence with the findings of previous studies on other populations. The mental foramen usually has symmetrical vertical location and appearance. Accessory foramina are recorded in a percentage lower than that recently reported in some regional countries.

“…Three accessory MFs were found in three Japanese cadavers and their diameters were 0.74 mm, 0.80 mm and 0.89 mm and were relatively smaller than normal MF [7]. Distances between MF and accessory MF were 0.67 mm, 2.1 mm and 5.74 mm [7].…”

“…In the study of sixty-nine adult Thai mandibles, the mean distance from the MF to the Symphysis Menti, lower border of the mandible and posterior border of the mandibular ramus was 28.83 mm, 68.85 mm and 14.88 mm respectively [6]. Three accessory MFs were found in three Japanese cadavers and their diameters were 0.74 mm, 0.80 mm and 0.89 mm and were relatively smaller than normal MF [7]. Distances between MF and accessory MF were 0.67 mm, 2.1 mm and 5.74 mm [7].…”

Introduction: Mental foramen (MF) is a small foramen situated in antero lateral aspect of the body of the mandible. It transmits mental nerve, artery and vein. Studying the position and its morphological variations of MF helps to localise the mental nerve which is a branch of the inferior alveolar nerve. It will help to prevent complications during invasive procedures at the mental region. The most common position of the MF is in-line with the longitudinal axis of the 2 nd pre-molar tooth followed by a location between the 1 st and the second pre-molar tooth. It is usually single and oval in shape.

“…Buccal foramina showing continuity without the MC are considered to be the so-called nutrient foramina (5). AMFs normally occur singly, but the number can range from 1 to 3 foramina per side (6)(7)(8).…”

A new sildenafil analogue was found to have been added illegally to a dietary supplement marketed for the enhancement of sexual function. The structure was determined as 5- (2-ethoxy-5-{[4-(3,5-Owing to the inclusion of a dimethyl group in acetildenafil, the detected compound was called dimethylacetildenafil. The sample was purified with column chromatography. The IR, LC/MS (ESI), and completely assigned NMR data of dimethylacetildenafil are reported for the first time. The structure was compared with that of acetildenafil and the results showed that the ethyl substitution at the 4-position of the piperazine ring had been replaced by a 3,5-dimethyl substitution. This new acetildenafil analogue was isolated and identified for the first time.
