“…As seen from the results, the majority of observed measurements were significantly less than calculated values, which means that Pont’s Index in general overestimates the dental arch widths values in Lithuanian individuals. This is in agreement with results of other studies, where overestimation of values were found [6,10,12-14]. Nimkarn et al [12] found that Pont’s Index overestimated interpremolar arch width by 4.7 mm and intermolar arch width by 2.5 mm.…”

“…Al-Omari et al [6] in a recent study reported low (r = 0.25 to 0.39) correlation between calculated and measured dental arch widths in Jordanians. In addition, Hong et al [10], in their study on Nepalese population, have found very low correlation (r = 0.07 to 0.29). On the other hand, studies, approving use of Pont’s Index are present as well.…”

ObjectivesA variety of diagnostic indices in orthodontics have been proposed to help in diagnosis and treatment planning. Pont’s Index was established to predict ideal maxillary dental arch width from the sum of mesiodistal widths of four upper incisors. The aim of this study was to assess the applicability of Pont’s Index to Lithuanian individuals.Material and MethodsThe sample comprised 52 subjects (age range from 18 to 35 years) with normal occlusion. Measurements were obtained directly from plaster casts using a digital calliper. Ideal arch widths were calculated for each subject according to Pont’s formulae, and the correlation coefficients were calculated between the measured and the calculated arch width values.ResultsCorrelation between the measured width values and the corresponding values calculated according to Pont’s Index was moderate in all cases, with correlation coefficients values ranging from 0.59 (mandible) to 0.64 (maxilla) in first premolar’s area and 0.49 in both maxilla and mandible in first molar’s area (P < 0.05). Appropriate index values for Lithuanian individuals were assessed to be 85.57 in premolars and 66.24 in molars area.ConclusionsAccording to the results of this study, there was no strong evidence to suggest that Pont’s Index could be reliably used to predict ideal arch width values in Lithuanian individuals.

“…Poznata je činjenica da se veličina zuba razlikuje između polova i populacija 1,[6][7][8][9]22 . Zbog toga je klinička primena Pontovog indeksa bila tema brojnih studija sa namerom da se odredi da li se može koristiti u predviđanju idealne širine zubnog luka kod pripadnika razičitih naroda [15][16][17][18]20,[23][24][25] .…”

Primena Pontovog indeksa u ortodontskoj dijagnostici koristi se za predviđanje idealne širine zubnog luka, neophodne za smeštaj zuba bez teskobe, pravilnu okluziju i postizanje stabilnih rezultata terapije. Cilj : ove studije bio je utvrditi primenljivost Pontovog indeksa u srpskoj populaciji i uporediti dobijene rezultate sa rezultatima ispitivanju u drugim populacijama. Materijal i metode: Analizirano je 200 studijskih modela osoba srpskog porekla (100 osoba muškog pola i 100 osoba ženskog pola). Svi ispitanici su bili sa klasom I po Angleu, bez prethodnog ortodontskog tretmana. Merenje je izvršeno pomoću digitalnog nonijusa (preciznost od 0,01 mm). Izmerene su meziodistalna širina maksilarnih stalnih sekutića, kao i interpremolarna i intermolarna širina maksilarnog luka. T-testom je uporedjena vrednost standardnog Pontovog indeksa i Pontovog indeksa dobijenog u istraživanju, kao i razlike dobijenih vrednosti izmedju polova. Određen je Pearsonov koeficijent korelacije između izmerenih i vrednosti širine zubnih lukova dobijenih korišćenjem Pontove formule. Rezultati: Rezultati ispitivanja pokazali su da su vrednosti za interpremolarnu i za intermolarnu širinu luka, izmerene na studijskim modelima pacijenata kod oba pola, manje nego vrednosti koje su dobijene primenom Pontove formule (p<0,001). Pearsonov koeficijent korelacije izmedju izmerenih vrednosti širine luka i vrednosti širine luka prema Pontovoj formuli pored visoke korelacije pokazuje statitički značajnu razliku (p<0,001). Zaključak: Dobijeni rezultati ukazuju da Pontov indeks nije primenljiv u srpskoj populaciji, te da su potrebni prilagodjeni populaciono specifični standardi za ovu dijagnostičku metodu.

The aim of this study was to determine the maxillary expansion index (MEI) for Pakistani population. Also to determine the sexual disparities in sum of incisors perimeter, arch width and expansion indices of maxillary arch. Hirox digital stereomicroscope was used for the fabrication of the digital models. The estimated sample size was 128 Pakistanis (64 females and 64 males; age range from18 -24 years). The perimeters of the maxillary permanent incisors, as well as intercanine, interpremolar, and intermolar arch widths, were measured on digital dental models. Significant sexual disparities were observed (***p < 0.001). There was significant difference observed in arch length and arch perimeter group of maxilla. For the prediction of ideal arch width in intercanine, interpremolar, and intermolar region to be achieved at the finishing stage, orthodontist can forecast the arch width before the initiation of orthodontic treatment. The new formula and the new indexes of arch width can be a helpful adjunct in the orthodontic treatment.
