Ubucwebe bezinyo zamaMaya ezenziwe nge-jade, igolide kunye nezinye izitye ezinqabileyo kunye namatye, mhlawumbi azizange zinike "igloss" kubanikazi bazo kuphela, kodwa zasebenza njengokuthintela i-caries kunye nesifo se-periodontal. Le propati yayinesamente, eyayincanyathiselwe kumazinyo abo bonke obu buhle, izazinzulu zaseMexico nase-United States zathi.
Abaphandi benkcubeko yamaMaya bayazi ukuba abameli bamandulo baba bantu babethanda kakhulu ukunika uncumo lwabo olongezelelweyo ubuhle, oko kukuthi, bagubungele amazinyo abo okanye baqhube imingxunya ukuze bafake "ukuzaliswa" kwe-jade, igolide, i-turquoise, i-jet okanye i-hematite. Oku kwenziwa kwakhona ngeenjongo zesithethe: ukuzaliswa kwagxininiswa kwi-incisors kunye ne-canines ekukhuleni kwabantu abadala, bahlala kunye nomntu ubomi kwaye mhlawumbi babenokubaluleka kokomoya.
Bonke obu bukhazikhazi babuncanyathiselwe emazinyweni ngoncedo lwesamente ekhethekileyo. Ubume bayo baphononongwa ngoososayensi abavela kwiYunivesithi yaseYucatan yase-Autonomous (eMexico), kunye neYunivesithi yaseHarvard kunye neBrown (USA). Babonise iziphumo zabo kwiphephancwadi i-Archaeological Science: Iingxelo. Amazinyo anqabileyo athathiwe kwiindawo zakudala eGuatemala, eBelize naseHonduras.
Kuphononongo, izazinzulu zichonge iimolekyuli ze-150 eziphilayo eziqhelekileyo ezifumaneka kwii-resin zezityalo. Ngokuxhomekeke kwindawo yemvelaphi yezinyo, i-samente, njengoko kwavela, yayinesethi eyahlukileyo yezinto, kodwa izithako eziphambili zifana.
Umxube wabo womelele ngokugqithisileyo. Kuyaqondakala, kuba amazinyo agqunywe ngamatye anqabileyo asekho nanamhlanje. Iingcali zenzululwazi zafumanisa ukuba amazinyo anjalo ayenziwa ngabantu abazizityebi kuphela, kodwa nabameli beeklasi ezingaphumelelanga kakhulu. Kwaye bobabini amadoda nabafazi.
Kodwa isiphelo esiphambili sababhali bomsebenzi sichaphazela iimpawu zonyango zesamente. Kwavela ukuba wayenempembelelo yokuphilisa kunye nococeko. Umxube we-adhesive, ngokutsho kwabaphandi, wakwazi ukunciphisa umngcipheko wokuvuvukala kunye nokusuleleka emlonyeni, ekubeni enye yezithako zayo eziphambili yayiyi-pine resin, enezinto ezilwa ne-antibacterial.
Izibilini ezisibhozo zokuzaliswa zitywinwe ngomxube oqukethe i-sclareolide, imveliso yendalo evela kwimithombo eyahlukeneyo yezityalo, kuquka i-sage kunye necuba. Le nto ineempembelelo ze-antibacterial kunye ne-antifungal. Ukongezelela, ivumba elimnandi, ngoko lisetyenziswa rhoqo kwi-perfumery. Ukongezelela, izazinzulu zifumene kwi-samente ioli ebalulekileyo yezityalo zentsapho ye-mint, nayo inefuthe elichasayo.
Ukugrunjwa kwenziwa ngobuchule kangangokuba kwakungafane kuchaphazele imithambo-luvo kunye nemithambo yegazi ekumbindi wezinyo. Ngendlela, abembi bezinto zakudala bayazi ukuba amaMayya ayenentlonipho malunga nokucoceka kwamazinyo, ngoko izigqibo zezazinzulu zibonakala zinyanisekile: umxube wesamente awunakusebenza nje ukulungisa isinyithi esinqabileyo kunye namatye, kodwa nokuthintela i-caries kunye nesifo se-periodontal.
